In addition to the sampling and analysis of the wells, tables will be prepared to provide data associated with the sampling event, outlining the numeric values resulting from the analyses, and figures will be prepared depicting the groundwater hydraulic gradient and contaminant/geochemical characteristics. Data generated from the sampling and analysis of groundwater from the Site will be used to monitor and evaluate the Site groundwater contaminant plume, augment data from previous Site groundwater sampling and analysis events, and to provide additional information for use by NCSU as to the attenuation of the plume by natural processes. This S&A Plan provides the sampling and analysis objectives, sampling and analysis methods to be utilized by the contractor and subcontractors, data quality and assurance goals for methods used, and health and safety concerns. 1.1 Site Background 1.1.1 Overview The Site and surrounding area is shown in Figure I, and a site map is provided in Figure 2. The NCSU Lot 86 Superfund Site received solvents, pesticides, heavy metals, acids, and some low-level radioactive laboratory wastes from 1969 to 1980. Chemical wastes were placed in trenches located in the northwest portion of the Site. Groundwater in the area of the Site contains volatile organic compounds (VOCs), including chloroform, methylene chloride, benzene, carbon tetrachloride, tetrachloroethene, and trichloroethene. Contaminant concentrations are highest in shallow groundwater adjacent to the Site and decrease with depth and with distance from the source area. NCSU's Department of Marine, Earth, and Atmospheric Sciences (MEAS) began monitoring the Site in 1981. The Site was proposed for listing on the National Priorities List (NPL) in October 1984 and was listed on the NPL in June 1986. The U. S. Environmental Protection Agency (EPA) began investigating the Site in 1987, and NCSU began a remedial investigation/feasibility study (RI/FS) of the Site in 1992. 4 I I I I I I I m I I I • I I u Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 The RI (Brown and Caldwell, 1994) focused on confirming the findings of earlier groundwater investigations. The FS (NCSU, 1996) examined a range of relatively conventional Site remediation approaches. For groundwater, approaches included institutional action, containment and capping, soil vapor extraction, incineration, and low-temperature thermal desorption. The evaluation of alternatives in the FS did not demonstrate that one alternative was preferable to the others. Following completion of the RI/FS, NCSU undertook an additional investigation to evaluate the content of the waste in the trenches, obtain updated groundwater quality data, and model the transport and biodegradation of four primary groundwater contaminants. The investigation determined that: 1) the depth of the trenches was 6 to 8 feet; 2) free and containerized liquid-phase chemical wastes remained in the trenches; 3) the wastes in the trenches continued to serve as a significant source of contaminants that can be released to groundwater; and 4) after the source ·materials were removed or stabilized, it is possible that the groundwater contaminant plume would be adequately controlled by natural biodegradation processes; and 5) the extent of the plume would be significantly larger than observed if not for the attenuating effects of contaminant biodegradation. Based on these findings, NCSU in 1996 evaluated natural attenuation as a remedial approach (N CSU, 1996) and prepared a revised FS that examined, among other alternatives, in-place stabilization of the trench materials and natural attenuation of groundwater contaminants. The earlier FS did not examine either of these alternatives, and the revised FS ranked these alternatives highest amongst all the alternatives. EPA issued its Record of Decision (ROD) for the Site in September 1996 (EPA, 1996). The selected remedy for source control consisted of treatment of the buried chemical waste and shallow soils impacted by the chemical waste, through in-situ mixing and encapsulation. The goal of the source remedy was to stabilize and solidify the chemical waste and shallow impacted soils into an impermeable and encapsulating matrix thus eliminating additional mass of chemical contaminants from subsurface transport processes . The presence of the impermeable monolith at the surface should eliminate vertical infiltration of storm water through the untreated and unsaturated soils beneath it. As such, new dissolution into water or displacement by water of residual contaminant mass held in the unsaturated soils beneath the monolith should be eliminated from subsurface transport dynamics. I The ROD for containment and/or treatment of the Site's residual risk after source removal is groundwater extraction and treatment until the following Remedial Action Objectives for impacted groundwater are reached. 5 I I I I I I I I I I • I I I I I I Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 Compound Benzene Carbon tetrachloride Chloroform Methylene chloride Tetrachloroethene Acetone Bromodichloromethane 1,2-Dichloropropane I, 1,2-Trichloroethane Trichloroethene Manganese Arsenic April 15, 2004 Remedial Action Objective (ug/L) I I I 5 I 700 I I I 2.8 370 10 The ROD allows deferral of the remedy to allow time for NCSU to develop and provide EPA with evidence demonstrating that "reduction of groundwater contamination is occurring at the Site by natural processes. If analytical results, such as but not limited to, a decrease of groundwater contamination or the existence of breakdown products of the original contaminants is presented, EPA will consider a change in remedy." The North Carolina Division of Waste Management concurred with this approach, provided that natural attenuation is evaluated using appropriate guidance. NCSU completed the ROD-mandated source remediation in September 1999. Evaluation of monitored natural attenuation as the sole remediation approach for groundwater contamination has shown the need for a groundwater extraction and treatment system to remove the highly contaminated groundwater close to the site. Based upon this assessment, the NCSU has restarted work on the design engineering for a groundwater extraction and treatment system. Concurrent with evaluating a monitored natural attenuation remedy for groundwater restoration, NCSU completed in September 1999 the source control measures specified in the ROD. In accordance with the Consent Decree, ROD, and EPA guidance identifying the components required of a natural attenuation demonstration, NCSU has concurrently initiated design engineering of a groundwater extraction and treatment system that could be implemented in the event that monitored natural attenuation is found to be not applicable for groundwater restoration at the Site, or does not progress as expected. 1.1.2 Waste Disposal History and Source Characterization NCSU reported on its CERCLA 103(c) Hazardous Waste Notification form filed with EPA on June 8, 1981, that it had disposed of approximately 300,000 cubic feet (11,000 cubic yards) of chemical waste at the Site. Chemical waste disposed by NCSU included waste solvents, pesticides, heavy metals, acids, and some low-level radioactive laboratory wastes. The chemical wastes were placed in trenches up to 8 feet deep from 1969 to 6 I I I I I I I I I I I I I I I I I I Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 1980. Chemical wastes disposed in the trenches were both solids and liquids, generally contained in metal, glass, or plastic containers. Some liquid wastes were reportedly poured directly to the trench. In January 1996, analytical characterization of soil samples from the waste disposal trenches was conducted. Six soil samples were analyzed for VOCs. Part per thousand concentrations (g/kg) of acetone, methylene chloride, benzene, and xylenes were variously reported. Other chlorinated and light aromatic VOCs, as well as semivolatiles, were detected in the trench soil samples. The impacted soils were described as generally fine-grained, low permeability silts and clays. In February 1998 NCSU conducted additional Site investigation to evaluate the nature and extent of buried waste. Under observation by Marshall Miller & Associates, six test pits were excavated with a backhoe to depths of 4 to 6 feet at locations throughout the waste burial area. Materials observed in the test pits included vials, bottles, and cans, many containing liquid; stained soils; intact drums and drum carcasses; powders; and sludge-like waste. The horizontal and vertical distribution of the materials was highly variable over the area of the test pits. An area of concentrated buried drums was identified in the northwest comer of the Site. In September 1999, the source control measures, consisting of the encapsulation of the upper ten feet of soil in the waste burial area, were completed. 1.1.3 Site Characterization The Site consists of 1.5 acres of land located in west Raleigh, North Carolina, directly south of Wade Avenue Extension and approximately 3,500 feet west of the interchange with Blue Ridge Road (Figure 1 ). The Site and the property abutting the Site are owned by the State of North Carolina. Land to the west of the Site is used for access and parking for Carter-Finley Stadium and the Entertainment and Sports Arena, which are located within 1,500 feet of the Site to the southwest and west, respectively. Land to the south of the Site is undeveloped wooded land. Land directly north of the Site consists of a wooded, steeply sloped (approximately 3.75:1) embankment down to the Wade Avenue Extension right-of-way. Groundwater flows from the Site in a predominantly west-northwest direction and is inferred to discharge to Richland Creek. Some component of groundwater flow may be to the north and east toward two tributary streams of Richland Stream. Current land uses and foreseeable land use changes in the area of the site are described as follows. • Wade Avenue Extension right-of-way is a divided, limited access highway that conveys a large daily volume of traffic between Raleigh to the east and Interstate 7 I I I I I I I I I I I I I I a g Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 40 to the west. The use of this highway right-of-way is not expected to change in the foreseeable future. • South of Wade Avenue Extension and east of Edwards Mill Road consists of woods, open fields, and drives and parking lots for Carter-Finley Stadium and the Entertainment and Sports Arena. Use of this area is not expected to change in the foreseeable future. • North of Wade Avenue Extension consists of woods and open fields with no improvements. This area is designated in a State of North Carolina 25-year development plan for development of a complex of State office buildings. The Site lies within the upland division of the Piedmont Physiographic Province of the Eastern United States. The Piedmont occurs as a wide belt extending along the eastern margin of the Appalachian Mountains extending from Alabama to the southern Hudson Valley ofNew York. Overburden soils, referred to as Saprolite, are described as typical Piedmont materials including silts, clays, sandy/clayey silts, and sandy/silty clays with minor amounts of fine to medium gravel. The generalized lithology is described as several feet of silty clay that transitions into micaceous sandy silt with depth. Materials become increasingly harder and denser with increasing depth, eventually transitioning into weathered rock then competent crystalline bedrock. Saprolite retains aspects of the parent bedrock, such as fractures and foliations. The residual soil/saprolite stratum at the Site has been described to range in thickness from 70 to 87 feet, although bedrock has been encountered at depths as shallow as 3 feet. Bedrock has been mapped in the area of the site as felsic gneiss and schist. The unit consists of felsic metamorphic rocks interlayered with mica-garnet schist, biotite gneiss, and hornblende gneiss. The rocks are described as occurring in a northeast-trending band approximately 4 miles wide in the west Raleigh area. Groundwater in the area of the Site occurs in the overburden soils and the underlying bedrock, generally under water-table (unconfined) conditions. Shallow groundwater is recharged by infiltration of precipitation through the ground surface. Recharge varies seasonally, with most occurring in the winter months when evapotranspiration losses are lowest. Groundwater in bedrock occurs along zones of secondary porosity, such as fractures, bedding planes, and foliations. The transmissivity of bedrock is dependent on the size and interconnectivity of these features. Bedrock is recharged primarily by the overlying soil/saprolite. 8 I I I I I I I I I I I I I I I g g a R Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April I 5, 2004 Groundwater flows at the Site predominantly toward the west-northwest in the shallow, intermediate, and bedrock strata. Measured depths to groundwater in the shallow, water- table, monitoring wells are typically 30 to 40 feet below grade in the former source area. A summary of Site monitoring well construction details is provided in Table I. The Site monitoring wells may be classified as shallow, intermediate, and deep monitoring wells by the following convention. CI 'ti f ass1 1ca 10n o om ormg e S IV en1 fM ·t .

To the extent possible, procedures and analyses conducted in the performance of the sampling and analysis of groundwater samples from the Site should: I) be representative of the conditions at the Site during the sampling event, 2) be consistent with the methods employed at the Site to conduct previous sampling events, 3) provide defensible data consistent with quality assurance and quality control plan(s) associated with the analyses, and 4) conform to the U.S. Environmental Protection Agency (US EPA) November 2001 Region TV Environmental Investigations Standard Operating Procedures and Quality Assurance Manual, the Draft EPA Region IV Suggested Practices for Evaluation of a Site For Natural Attenuation (Biological Degradation) of Chlorinated Solvents, and the Technical Protocol for Evaluating Natural Attenuation of Chlorinated Solvents in Groundwater (EPA/600/R-98/J 28)1• 1 Note: Any discrepancies noted to exist between the U.S. Environmental Protection Agency (US EPA) November 2001 Region IV Environmental Investigations Standard Operating Procedures and Quality Assurance Manual, the Draft El' A Region IV Suggested Practices for Evaluation of a Site For Natural Attenuation (Biological Degradation) of Chlorinated Solvents and the Technical Protocol for Evaluating Natural Attenuation of Chlorinated Solvents in Groundwater (EPA/600/R-98/128) will weigh in favor of the Technical Protocol. 9 I I I I I I I I I I I I I g g Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 Further objectives of the sampling and analysis of groundwater samples from the Site include the assurance of the safety of the persons conducting the sampling event, and the mitigation of any potential for additional damage to the environment through the improper performance of the tasks associated with the sampling and analysis. 3.0 HEAL TH AND SAFETY A Health and Safety Plan (H&S Plan) for the performance of the sampling event is presented in Appendix A. The H&S Plan outlines the methods to be employed to protect personnel from potential hazards associated with well sampling at the Site. Personnel to be involved in the conduct of the groundwater-sampling event will have been trained in accordance with the Occupational Safety and Health Administration ( OSHA) Title 29, Code of Federal Regulations (CFR) 1910.1200. The H&S Plan includes provisions for personnel protective equipment (PPE) to be utilized during the performance of the sampling event and precautions necessary to ensure a safe work environment. 4.0 GROUNDWATER SAMPLING AND ANALYSIS Groundwater sampling and analysis will be conducted in accordance with procedures described in the EPA Region IV Environmental Investigations Standard Operating Procedures and Quality Assurance Manual (EISOPQAM)(November 200 I). 4.1 Preparations for Groundwater Sampling 4.1.l Water Level Measurements The locations of the wells targeted for sampling are depicted on Figure 2. The initial activity to be conducted in the performance of groundwater sampling at the Site will entail the measurement of static water levels within each well targeted for sampling under this ·s&A Plan. Each well targeted for sampling during this event will be inspected, including notation of the condition of the outer protective casings, seals, well caps and locks. Any discrepancies observed to exist will be noted, and recommended corrective actions to repair the discrepancies will be forwarded to NCSU. Scheduling and performance of corrective actions to correct discrepancies will be performed at the discretion and direction of NCSU. Prior to the measurement of static water levels, each well will be opened and sufficient time will be allowed for groundwater levels to stabilize. At the time of opening, the air within the headspace of each well will monitored for volatile vapors utilizing an organic vapor analyzer (OVA). Values obtained in the performance of OVA measurements will be recorded in a field book and later integrated into an Excel® spreadsheet for use by NCSU. Water level measurements 10 I I I I I I I I I I I g a u D Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 will be collected first from the historically "clean" wells (i.e., wells that have not indicated the presence of targeted contaminants) and subsequently from contaminated wells (i.e., wells that have previously indicated the presence of contaminants). In the case of contaminated wells, measurements will proceed from wells showing the least contaminants to wells with the most contaminants. This procedure for measuring water levels is intended to decrease the potential for cross-contamination between wells located at the Site. Subsequent to stabilization, each well will be gauged with a conductive water level indicator. Measurement of static water levels will be accomplished though lowering of the indicator probe into the well(s). The water level measurement (relative to the top of casing of the well or a reference mark on the well previously established/ will be recorded for each well, for later use in the data package and hydraulic gradient calculations. If not already known the total depth of each well, e.g.-"depth to bottom" will be measured and recorded for use in calculating the purge volume(s) for each well. Between measuring locations, the water level indicator will be decontaminated in accordance with the decontamination procedures outlined in Appendix B of the EISOPQAM, a copy of which is provided in Appendix B of this workplan. At the conclusion of the groundwater sampling activities, data obtained in the measurement of water level elevations will be entered in to an Excel® spreadsheet for use byNCSU. 4.1.2 Well Purging Well purging at the Site will be performed in accordance with the provisions of Section 7 of the ElSOPQAM. Purging is the process of removing stagnant water from a monitoring well, immediately prior to sampling, causing its replacement by ground water from the adjacent formation, which is representative of actual aquifer conditions. In order to determine when a well has been adequately purged, field investigators will: 1) monitor the pH, specific conductance, temperature, and turbidity of the ground water removed during purging; and 2) observe and record the volume of water removed. Prior to initiating the purge, the amount of water standing in the water column (water inside the well riser and screen) will be determined. To do this, the diameter of the well will be determined and the water level and total depth of the well will be measured and recorded. Prior to the collection of groundwater samples at the Site, each of the 34 wells slated for sampling will be purged of a minimum of three (3) volumes of water, based on the well 2 In the event that no reference mark is available for a well or wells, the water level measurement will be performed to the highest vertical point of the well casing. 11 I I I I I I I I I I g 0 Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 volumes as calculated with the static and "depth to bottom" measurements obtained through Water Level Measurements. Volumes of groundwater to be purged from each of the wells will be based the following formula: V = 0.041 d2h Where:h = depth of water in feet d = diameter of well in inches v = volume of water in gallons Additional information related to purge techniques is available m Section 7 of the EISOPQAM, a copy of which is presented in Appendix C. Monitoring well purging will be accomplished using in-place plumbing and dedicated pumps or, by using portable pumps/equipment if dedicated systems are not present. The equipment may consist of a variety of pumps, including peristaltic, large and small diameter turbine ( electric submersible), bladder, centrifugal, gear-driven positive displacement, or other appropriate pumps. The use of any of these pumps will be a function of the depth of the well being sampled and the amount of water to be removed during purging. Bailers may also be used for purging in appropriate situations. However, the use of hailers will be discouraged. Bailers tend to disturb any sediment that may be present in the well, creating or increasing sample turbidity. If a bailer is used, it will be a Teflon® or PVC bailer. Purging with Pumps When peristaltic pumps or centrifugal pumps are used, the intake line only will be placed into the water colunm. The line placed into the water will be either standard-cleaned (see Appendix B) Teflon® tubing, for peristaltic pumps, or standard-cleaned stainless steel pipe attached to a hose for centrifugal pumps. When submersible pumps (bladder, turbine, displacement, etc.) are used, the pump itself will be lowered into the water column. The pump will be cleaned as specified in Appendix B. Purging with Bailers Standard-cleaned (Appendix B) Teflon® or PVC hailers, or dedicated, disposable, polyethylene hailers, with dedicated, disposable, nylon rope will be lowered into top of the water column, allowed to fill, and removed. The water will either be discarded or contained and managed as investigation derived waste. It is critical that hailers be slowly and gently immersed into the top of the water column, particularly during final stages of purging, to minimize turbidity and disturbance of volatile organic constituents. The use of hailers for purging and sampling will be discouraged because the correct technique is highly operator dependent. 12 I I I I I I I I I I I I Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 Field Care of Purging Equipment Regardless of which method is used for purging, new plastic sheeting will be placed on the ground surface around the well casing to prevent contamination of the pumps, hoses, ropes, etc., in the event they need to be placed on the ground during the purging or they accidentally come into contact with the ground surface. It is preferable that hoses used in purging that come into contact with the ground water be kept on a spool or contained in a plastic-lined tub, both during transporting and during field use, to further minimize contamination from the transporting vehicle or ground surface. Purging Entire Water Column The pump/hose assembly or bailer used in purging will be lowered into the top of the standing water column and not deep into the column. This will be done so that the purging will "pull" water from the formation into the screened area of the well and up through the casing so that the entire static volume can be removed. If the pump is placed deep into the water column, the water above the pump may not be removed, and the subsequent samples, particularly if collected with a bailer, may not be representative of the ground water. No more than three to five feet of hose will be lowered into the water column. If the recovery rate of the well is faster than the pump rate and no observable draw down occurs, the pump will be raised until the intake is within one foot of the top of the water column for the duration of purging. If the pump rate exceeds the recovery rate of the well, the pump will be lowered, as needed, to accommodate the drawdown. After the pump is removed from the well, all wetted portions of the hose and the pump will be cleaned as outlined in Appendix B. Careful consideration will be given to using pumps to purge wells that are excessively contaminated with oily compounds, because it may be difficult to adequately decontaminate severely contaminated pumps under field conditions. When wells of this type are encountered, alternative purging methods, such as hailers, should be considered. General Low Flow/Low Stress Method Preference The device with the lowest pump or water removal rate and the least tendency to stress the well during purging will be selected for use. For example, if a bailer and a peristaltic pump both work in a given situation, the pump will be selected because it will minimize turbidity, providing a higher quality sample. If a Fultz® pump or a Grundfos Redi- Flo2® could both be used, the Redi-Flo2® may be given preference because the speed can be controlled to provide a lower pump rate, thereby minimizing turbidity. Purging of groundwater from each well targeted for sampling, excepting those wells with "slow" recovery rates and short water columns (a described below), will be accomplished through the use of a Grundfos Redi-Flo 2® electric submersible pump (or equivalent). Wells with "slow" recovery rates and short water columns will be purged as outlined below. Dedicated tubing (1/2-inch diameter polybutylene) already existing in each well will be utilized for purging. Well purging will be collected first on the historically "clean" wells (i.e., wells that have not indicated the presence of targeted contaminants) and subsequently from contaminated 13 I I I I I I I I I I I I I I I Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 wells (i.e., wells that have previously indicated the presence of contaminants). In the case of contaminated wells, purging will proceed from wells showing the least contaminants to wells with the most contaminants. This procedure for well purging is intended to decrease the potential for cross-contamination between wells located at the Site. Between locations, the pump and controlling leads will be de-contaminated in accordance with the decontamination procedures outlined in Appendix B. Purging of those wells with appreciable recovery rates will be conducted through the lowering of the pump into the well, ensuring that the pump intake is situated in the upper portion of the screened section of the well. The pump will then be energized, and the discharge flow rate will be adjusted to ensure proper recharge of the well. Purge water generated during the process will be contained as outlined in 4.1.2.1, below. During the purge procedures to be conducted for each well, monitoring of the following "field parameters" will be conducted: a) b) c) d) e) pH (standard units), Conductivity, Temperature, Dissolved Oxygen3, and Oxidation-Reduction Potential Prior to sampling, each monitoring well will be purged a minimum of three static well volumes and until field parameter measurements stabilize within the following limits, or until a maximum of five static well volumes are removed. • pH: ±0. J units; • Turbidity: ±IO nephelometric turbidity units; • Specific conductance: ±I 0%; • Temperature: constant (±<I° C) for three consecutive measurements. Field parameter measurements are discussed further in 4.3.1, below. Monitoring wells MWl3, MW15, MW-27 and MW29 are low yielding that could not be purged without going "dry" during previous sampling events. For these wells, and potentially for wells MW3, MWII, MW-16, MWl61, MW17, MW35S, MW38 and MW4 l (wells which also in the past have demonstrated "slow" recovery), alternate methods for the purging and sampling may be anticipated. 3 Measurement of dissolved oxygen for those wells purged utilizing an electric pump will be performed utilizing a flow through chamber. 14 I I I I I I I I I I I I I I g u u Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 Wells, which have been historically slow in recovering (i.e., have been purged dry during previous sampling event) and contain more than a 3-foot column of groundwater will be purged using a submersible pump as described above for higher-yielding wells. In purging these wells, the flow rate of the submersible pump will be adjusted to the lowest setting possible to sustain flow. In order to avoid damage to the submersible pump due to pumping from a short, and potentially turbid, water column, low yielding monitoring wells containing less than a 3-foot column of groundwater will be purged utilizing (new) disposable hailers and (new) nylon line. Water will be removed from these wells by lowering the bailer into the water column within the well, and extracting the bailer when full. This procedure will be repeated in these wells until the purge criteria described above are met or the well is purged dry. In the event of the latter condition, a groundwater sample will be collected from the well upon at least 80% recovery of the static groundwater level or within 24 hours of the completion of purging, whichever occurs first. Additional information related to purge techniques is available in Section 7 of the EISOPQAM, a copy of which is presented in Appendix C of this workplan. 4.1.2.1 Purge Water Containment Purge water extracted from the wells will be removed through dedicated tubing or hailers (as described in 4.1.2, above) and temporarily stored in truck-mounted polyethylene tank(s). Water will be transferred from the polyethylene tank(s) into 55-gallon IA2-UN or I H2-UN DOT approved drums to be located at Lot 86 within the fenced area. It is anticipated that twelve (12) 55-gallon drums will have to be utilized in the performance of each sampling event, all of which will be impounded at the Lot 86 location. Purge water will be handled according to the well from which the water was generated; water generated in the purging of historically clean wells MW-13, MW-13D, MW-16D, MW-27, MW29, MW33, MW34SR, MW-34DR, MW-35S, MW35D, MW40, MW-41, MW-411, MW-41D, MW-42, MW-42I, MW43, MW45, MW46, and MW-47 will be discharged directly to the surface in the area surrounding the well location 4. Spill containment supplies will be maintained on all vehicles in use at the location for the implementation of spill response, if necessary. Each drum of waste generated during the process will be labeled in accordance with EPA and Department of Transportation (DOT) guidelines and will bear the designation for each well from which the purge water was generated. Purge water contained in 55-gallon drums and stored at the fenced location of Lot 86 will, subsequent to the sampling event, be disposed of by, and at the discretion of NCSU. 4 In a meeting with Mr. Duane Knudson (NCSU) and Mr. David Mattison (NCDENR-DWM) on March 20, 200 I, Mr. Mattison staled that it would be acceptable for the disposal of purge water from historically "clean" wells in this manner. 15 I I I I I I I I I I I I I I n 4.1.2.2 Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 Decontamination Procedures Cleaning procedures in this section are intended for use by field personnel for cleaning sampling and other equipment in the field. Emergency field sample container cleaning procedures are also included; however, they should not be used unless absolutely necessary. Sampling and field equipment cleaned in accordance with these procedures must meet the minimum requirements for Data Quality Objectives (DQO) definitive data collection. Deviations from these procedures should be documented in the approved study plan, field records, and investigative reports. These are the materials, methods, and procedures to be used when cleaning sampling and other equipment in the field. Specifications for Cleaning Materials Specifications for standard cleaning materials referred to in this S&A Plan are as follows: • Soap shall be a standard brand of phosphate-free laboratory detergent such as Liquinox®. Use of other detergent must be justified and documented in the field logbooks and inspection or investigative reports. • Solvent shall be pesticide-grade isopropanol. Use of a solvent other than pesticide-grade isopropanol for equipment cleaning purposes must be justified in the study plan. Otherwise its use will be documented in field logbooks and inspection or investigation reports. • Tap water may be used from any municipal water treatment system. Untreated potable water supply will not be substituted for tap water. • Analyte free water (deionized water) is tap water that has been treated by passing through a standard deionizing resin column. At a minimum, the finished water will contain no detectable heavy metals or other inorganic compounds (i.e., at or above analytical detection limits) as defined by a standard inductively coupled Argon Plasma Spectrophotometer (ICP) (or equivalent) scan. Analyte free water obtained by other methods will be acceptable, as long as it meets the above analytical criteria. • Organic/analyte free water is defined as tap water that has been treated with activated carbon and deionizing units. A portable system to produce organic/analyte free water under field conditions is available. At a minimum, the finished water will meet the analytical criteria of analyte free water and contain no detectable pesticides, herbicides, extractable organic compounds, or volatile organic compounds above minimum detectable levels as determined by the Region 4 laboratory for a given set of analyses. Organic/analyte free water obtained by other methods will be acceptable, as long as it meets the above analytical criteria. • Other solvents may be substituted for a particular purpose if required. For example, removal of concentrated waste materials may require the use of either pesticide-grade hexane or petroleum ether. After the waste material is removed, the equipment will be subjected to the standard cleaning procedure. Because these 16 I I I I I I I I I I • I u n H D Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 solvents are not miscible with water, the equipment will be completely dry prior to use. Solvents, laboratory detergent, and rinse waters used to clean equipment shall not be reused during field decontamination. Handling and Containers for Cleaning Solutions Improperly handled cleaning solutions may easily become contaminated. Storage and application containers will be constructed of the proper materials to ensure their integrity. Following are acceptable materials for storage of the specified cleaning solutions: • Soap will be kept in clean plastic, metal, or glass containers until used and will be poured directly from the container during use. • Solvent will be stored in the unopened original containers until used. Solvents will be applied using the low-pressure nitrogen system fitted with a Teflon® nozzle, or using Teflon® or plastic squeeze bottles. • Tap water will be kept in clean tanks, hand pressure sprayers, squeeze bottles, or applied directly from a hose. • Analyte free water will be stored in clean glass, stainless steel, or plastic containers that can be closed prior to use and may be dispensed from plastic squeeze bottles. • Organic/analyte free water will be stored in clean glass, Teflon®, or stainless steel containers prior to use and may be dispensed using Teflon® squeeze bottles or the portable system. Note: Hand pump sprayers generally are not acceptable storage or application containers for the above materials (with the exception of tap water). This also applies to stainless steel sprayers. All hand sprayers have internal oil coated gaskets and black rubber seals that may contaminate the solutions. Disposal of Solvent Cleaning Solutions Investigation derived waste (IDW), including used wash water, rinse water, and spent solvents will be transferred to a 55-gallon I A2-UN or I H2-UN DOT approved drum. The drum will be labeled in accordance with EPA and Department of Transportation (DOT) guidelines and will bear a description of the generation process. The drum will be stored at the fenced location of Lot 86 and will, subsequent to the sampling event, be disposed ofby, and at the discretion ofNCSU. Equipment Contaminated with Concentrated Wastes Equipment used to collect samples of hazardous materials or toxic wastes or materials from hazardous waste sites, RCRA facilities, or in-process waste streams will be field cleaned before returning from the study. At a minimum, this will consist of washing with soap and rinsing with tap water. More stringent procedures may be required at the discretion of the field investigators. 17 I I I I I I I I I I I I n n H 0 Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 Safety Procedures for Field Cleaning Operations Some of the materials used to implement the cleaning procedures outlined in this S&A Plan may be harmful if used improperly. All field investigators shall exercise caution and all applicable safety procedures shall be followed. At a minimum, the following precautions will be taken in the field during these cleaning operations: • Safety glasses with splash shields or goggles, and latex gloves will be worn during all cleaning operations. • Solvent rinsing operations will be conducted in the open (never in a closed room). • No eating, smoking, drinking, chewing, or any hand to mouth contact will be permitted during cleaning operations. Handling of Cleaned Equipment After field cleaning, equipment will be handled only by personnel wearing clean nitrile or equivalent gloves to prevent re-contamination. In addition, the equipment will be moved away (preferably upwind) from the cleaning area to prevent recontamination. If the equipment is not to be immediately re-used it will be covered with plastic sheeting or wrapped in aluminum foil to prevent re-contamination. The area where the equipment is staged prior to re-use will be kept free of contaminants. "Classic Parameter" Sampling Equipment "Classic Parameters" are analyses such as oxygen demand, nutrients, certain inorganics, sulfide, flow measurements, etc. For routine operations involving classic parameter analyses, water quality sampling equipment such as Kemmerers, buckets, dissolved oxygen dunkers, dredges, etc., will be cleaned with the sample or analyte-free water between sampling locations. A brush may be used to remove deposits of material or sediment, if necessary. Flow measuring equipment such as weirs, staff gages, velocity meters, and other stream gauging equipment will be cleaned with tap water between measuring locations, if necessary. The previously described procedures are not to be used for cleaning field equipment to be used for the collection of samples undergoing trace organic or inorganic constituent analyses. Sampling Equipment used for the Collection of Trace Organic and Inorganic Compounds The following procedures will be used for all sampling equipment used to collect routine samples undergoing trace organic or inorganic constituent analyses: I. Clean with tap water and soap using a brush, if necessary, to remove particulate matter and surface films. Equipment may be steam cleaned (soap and high pressure hot water) as an alternative to brushing. Sampling equipment that is steam cleaned should be placed on racks or saw horses at least two feet above the floor of the decontamination pad. PVC or plastic items will not be steam cleaned. 18 I I I I I I I I I I I I I g u 0 D 0 Groundwater Sampling and Analysis Plan Nonh Carolina State University Lot 86 Site Version 1.0 April 15, 2004 2. Rinse thoroughly with tap water. 3. Rinse thoroughly with analyte free water. 4. Rinse thoroughly with solvent. Do not solvent rinse PVC or plastic items. 5. Rinse thoroughly with organic/analyte free water. If organic/analyte free water is not available, equipment should be allowed to completely dry. Do not apply a final rinse with analyte water. Organic/analyte free water can be generated on-site utilizing the portable system. 6. Remove the equipment from the decontamination area and cover with plastic. Equipment stored overnight will be covered with clean, unused plastic. Well Sounders or Tapes Well sounders or tapes used to measure well levels and depths will be cleaned prior to each use and between each monitoring well as follows. I. Wash with soap and tap water. 2. Rinse with tap water. 3. Rinse with analyte free water. Redi-Flo2® Pump The Redi-Flo2® pump will be cleaned prior to use and between each monitoring well using the following procedure. CA UT/ON -Make sure the pump is not plugged in. I. Using a brush, scrub the exterior of the pump, electrical cord and garden hose with soap and tap water. Do not wet the electrical plug. 2. Rinse with tap water. 3. Rinse with analyte free water. 4. Place the equipment in a clean plastic bag. To clean the Redi-Flo2® ball check valve: I. Completely dismantle ball check valve. Check for wear and/or corrosion, and replace as needed. 2. Using a brush, scrub all components with soap and tap water. 3. Rinse with analyte free water. 4. Reassemble and re-attach the ball check valve to the Redi-Flo2® pump head. Additional information related to decontamination procedures are presented in Appendix B. 19 I I I I I I I I I I I I I a g u D 0 4.2 Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 Groundwater Sampling 4.2.1 Standard Sample Collection Procedures Groundwater sampling from each Site monitoring well (totaling 39) will be performed subsequent to proper purging of the well. Samples retained from each well will be submitted for fixed based analysis by a North Carolina Department of Environment and Natural Resources (NCDENR) Division of Water Quality (DWQ) certified laboratory. Additional laboratory information is provided in 4.3.2, below. Fixed based parameters will be measured for each well sampled through the analysis of groundwater samples. Fixed-base parameters for these samples will include the analysis of the sample(s) for: a) Aromatic and Chlorinated hydrocarbons by EPA Method 6230 D, b) Nitrate, c) Dissolved Iron (II), d) Sulfate, e) Methane, ethane, ethene, t) Alkalinity, g) Major cations (RCRA Metals) including Manganese (Mn), h) Chloride, and i) Total organic carbon Samples retrieved from each well will be contained in pre-cleaned laboratory grade containers to be provided by the Laboratory. As described in 4.3.2.1, sample containers requiring chemical preservation will be preserved in advance by the Laboratory. The QA Package for the laboratory will include a Method Blank, Matrix Spike/Matrix Spike Duplicate, Laboratory Fortified Blank and Surrogate Standard % Recoveries. If possible, each well will be sampled immediately upon completion of purging. If the well is evacuated dry during the purging procedures, the groundwater sample will be collected from the well upon at least 80% recovery of the static groundwater level or within 24 hours of the completion of purging, whichever occurs first. Following purging, samples may be collected using a peristaltic pump, a Teflon®/stainless steel bladder pump, Teflon® or PVC hailers with dedicated, disposable nylon rope, and/or dedicated, disposable, polyethylene hailers with dedicated, disposable nylon rope. These techniques are described below. Bladder Pumps/Peristaltic Pumps After purging has been accomplished with a bladder or peristaltic pump, the sample may be obtained directly from the pump discharge. The pump discharge rate will be reduced 20 I I I I I I I I I I u 0 n D 0 Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 to <l 00 ml/minute prior to collecting samples to mm1m1ze sample disturbance, particularly with respect to samples collected for volatile organic compounds analysis. Bailers When bailing, new plastic sheeting will be placed on the ground around each well to provide a clean working area. The nylon rope may be attached directly to the bailer or through a Teflon® coated stainless steel wire. The coated wire will be decontaminated for reuse with the bailer. The bailer will be gently immersed in the top of the water column until just filled, carefully removed, and the contents emptied into the appropriate sample containers. 4.2.2 Special Sample Collection Procedures Trace Organic Compounds and Metals Special sample handling procedures will be instituted when trace contaminant samples are being collected. All sampling equipment, including pumps, hailers, water level measurement equipment, etc., which comes into contact with the water in the well will be cleaned in accordance with the cleaning procedures described in Appendix B. Pumps will not be used for sampling, unless the interior and exterior portions of the pump and the discharge hoses are thoroughly cleaned. Blank samples will be collected to determine the adequacy of cleaning prior to collection of any sample using a pump. Filtering As a standard practice, ground water samples will not be filtered for routine analysis except for the samples to be analyzed for dissolved iron. Filtering will only be performed to determine the fraction of major ions and trace metals passing the filter and used for flow system analysis and for the purpose of geochemical speciation modeling. Filtration will not be allowed to correct for improperly designed or constructed monitoring wells, inappropriate sampling methods, or poor sampling technique. When samples are collected for routine analyses and are filtered, such as under conditions of excessive turbidity, both filtered and non-filtered samples will be submitted for analyses. Samples for organic compounds analysis will not be filtered. Prior to filtration of the ground water sample for any reason other than dissolved iron analysis or geochemical speciation modeling, the following criteria must be demonstrated to justify the use of filtered samples for inorganic analysis: I. The monitoring wells, whether temporary or permanent, have been constructed and developed in accordance with the provisions of the EPA Region IV ElSOPQAM. 2. The ground water samples were collected using sampling techniques in accordance with this section, and the ground water samples were analyzed in accordance with US-EPA approved methods. 3. Efforts have been undertaken to minimize any persistent sample turbidity problems. These efforts consist of the following: 21 I I I I I I I I I I I I I I I I I I I Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 • Redevelopment or re-installation of permanent ground water monitoring wells. • Implementation of low flow/low stress purging and sampling techniques. Groundwater turbidity measurements will be taken during purging and sampling to demonstrate stabilization or lack thereof. These measurements should be documented in the field notes. If the groundwater sample appears to have either a chemically-induced elevated turbidity, such as would occur with precipitate formation, or a naturally elevated colloid or fine, particulate-related turbidity, filtration will not be allowed. If filtration is necessary for purposes of geochemical modeling or other pre-approved cases, the following procedures will be used: • In-line filtration through the use of disposable, high capacity filter cartridges (barrel-type) or membrane filters in an in-line filter apparatus. The high capacity, barrel-type filter will be preferred due to the higher surface area associated with this configuration. If a membrane filter is utilized, a minimum diameter of 142 mm is suggested. • 5 µm pore-size filter for the purpose of determining the colloidal constituent concentrations. A 0.1 µm pore-size filter should be used to remove most non- dissolved particles. • Cartridge or barrel-type filter will be flushed with 500 milliliters of the solute (ground water to be sampled) prior to collection of sample. If a membrane filter is · used, it will be rinsed with 100 milliliters of solute prior to sample collection. Potential differences could result from variations in filtration procedures used to process water samples for the determination of trace element concentrations. A number of factors associated with filtration can substantially alter "dissolved" trace element concentrations; these include filter pore size, filter type, filter diameter, filtration method, volume of sample processed, suspended sediment concentration, suspended sediment grain-size distribution, concentration of colloids and colloidally-associated trace elements, and concentration of organic matter. Therefore, consistency is critical in the comparison of short-term and long-term results. Further guidance on filtration may be obtained from the following: 1) Metals in ground Water: Sampling Artifacts and Reproducibility (3); 2) Filtration of Ground Water Samples for Metals Analysis (4); and 3) Ground Water Sampling - A Workshop Summary (5). Specific Sampling Equipment Quality Assurance Techniques All equipment used to collect ground water samples shall be cleaned as outlined in Appendix B and repaired, if necessary, before being stored at the conclusion of field studies. Cleaning procedures utilized in the field (Appendix B), or field repairs shall be thoroughly documented in field records. · In the case of wells for which purging is performed with an electric submersible pump, samples will be retrieved from a sample port to be located on the flow through chamber used in the collection of field measured parameters. In the case of wells requiring 22 I I I I I I I :I I I I I I I I I I I I I Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 purging utilizing a disposable bailer, samples will be collected from the bailer. Samples for fixed base analyses will be contained in pre-washed, laboratory grade containers to be provided by the laboratory. A listing of containers and required preservatives (if applicable) are discussed in 4,3,2, below. Subsequent to the collection of groundwater samples, the containers in which samples have been contained will be placed on ice in a cooler, pending transportation to the lab for analysis. All chain-of custody protocol and outlined in 4,3,2,3 will be strictly adhered to in the performance of this sampling event.

Any samples collected using out-of- protocol procedures will be discarded, and replacement samples will be collected. Any QNQC issues and corrective actions will be documented by the project leader for the project file. 4.3 Groundwater Analysis 4.3.1 Field Base Measurements During the purge procedures to be conducted for each well, monitoring of the following field parameters will be conducted: a) pH (standard units), b) Conductivity, c) Temperature, d) Dissolved Oxygen, e) Oxidation-Reduction Potential, and f) Turbidity. Measurement of the field parameters will be conducted during the purging of each well, after sufficient volume(s) of groundwater have been removed from the well(s) to provide reliable data. Dissolved oxygen measurements will be performed utilizing a flow through chamber. Operation and maintenance manuals for the instruments to be utilized in the performance of this sampling event are presented in Appendix D. Field measurements obtained during the performance of this project will be noted in a field book, and later entered into an Excel® spreadsheet for submittal to NCSU. 25 I I I I I I I I I I I I I I I I I I I Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 Additional information related to Field Measurable Physical/Chemical Characteristics is available in Section 16 of the EPA Region IV EISOPQAM, a copy of which is presented in Appendix E. 4.3.1.1 Hydrogen Ion Concentration (pH) The pH is defined as the negative logarithm of the effective hydrogen-ion concentration or hydrogen-ion activity in grams equivalents per liter used in expressing both acidity and alkalinity on a scale which ranges from Oto 14 with 7 representing neutrality. Meters available: • Orion Model 399A • Orion SA 250 or 230A • Hydrolab Surveyor II • YSI 3530, 3500 Water Quality Monitoring System • I-loriba U-10 or U-22 • Cole-Parmer Model 10 Calibration: Follow manufacturer's instructions with the following as a minimum. Note: The pH of the sample to be tested should be estimated either from historical data or by using a four- color pH indicator paper or equivalent. Using this information, the two buffering points for calibration can be determined. I. Remove the meter from storage and allow it to equilibrate to ambient temperature. 2. Measure and record the temperature of the buffering solutions. 3. Select either pH 4 and pH 7 or pH 7 and pH 10 solutions as described above. 4. Rinse the probe with analyte-free water and calibrate to the first buffer (pH 7). 5. Rinse the probe with analyte-free water and calibrate to the second buffer. 6. Rinse and store the probe in a container filled with analyte-free water. Sample Measurement Procedure: 1. Collect a sample. Measure the temperature prior to measuring the pH. Note: If the temperature of the sample differs by more than 2°C or approximately 4°F, refer to the manufacturers instructions on how to adjust for temperature variations. Note: When the pl-I meter response is slow, unstable, or non-reproducible, it may be necessary to check the conductivity. If the conductivity is lower than 20 to 30 mhos/cm then add I ml of IM potassium chloride solution per I 00 mis of sample. Recheck the pH and record. 2. Immerse the probe in the sample keeping it away form the sides and bottom of the sample container. Allow ample time for the probe to equilibrate with the sample. 3. While suspending the probe away from the sides and bottom of the sample container, record the pH. 4. Rinse the probe with analyte-free water and store it in analyte-free water filled container until the next sample is ready. 26 I I I I I I I I I I I I I I I I I I I Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 Operational check: I. While in use, periodically check the pH by rinsing the probe with analyte-free water and immersing it into the pH 7 buffer solution. 2. Perform a post calibration at the end of the day and record all findings. Units: Units of pH are Standard Units (SU) and should be read in one-hundredths (0.01) and recorded in tenths (0.1 ). Note: If the pH measurements are to be used for RCRA regulatory purposes and when the pH approaches the alkaline end (pH > I 1.0) of the scale, the pH measurements should be made by a qualified analyst using laboratory quality equipment to control the sample at 25°C ± I °C. 4.3.1.2 Specific Conductance (Conductivity) Conductivity is defined as the quality or power of conducting or transmitting. Meters available: • Wheatstone bridge meters. • Horiba U-10 or U-22. • Cole-Parmer Model I 0. Calibration: The meter should be calibrated in accordance with the manufacturer's instructions. A two-point standard should be used to insure the accuracy of the meter. Conductivity may be affected by temperature; therefore, temperature should be read first so that appropriate adjustments can be made in accordance to the manufactures instructions. I. Check and record the temperature of the standard solutions. 2. Rinse the probe with analyte-free water before immersing it in the standards solution. 3. Immerse the probe in the first standard solution and record the results. Note: Make sure the meter is "ON". 4. Rinse the probe and immerse it into the second standard solution and record results. Note: If the meter is not accurate to within± 10% of the standards, correct the problem before proceeding. Sample Measurement Procedure: I. Collect the sample and check and record its temperature. 2. Correct the instruments temperature adjustment to the temperature of the sample. 3. Immerse the probe in the sample keeping it away from the sides and bottom of the container. It is important that the entire portion of the probe be wetted by the sample. This will be evident when some of the sample water is seen coming out of the small weep hole. 27 I I I I I I I I I I I 11 I I I I I I I Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 4. Record the results in a log book. 5. Rinse probe. Units: Conductivity units are measured in milliSiemens per centimeter (mS/cm) at 25°C. Results should be reported to the nearest 0.1 mS/cm for readings below IO mS/cm @ 25°C and to the nearest l mS/cm for reading above IO mS/cm @ 25°C. 4.3.1.3 Temperature Temperature is a measure of hotness or coldness on a defined scale. Meters available: • Digital (thermo-couple) thermistor. • Glass bulb mercury filled. • Bi-metal strip/dial indicator. • Horiba U-l O or U-22. • Cole-Parmer Model I 0. • YSI Model 95. Calibration: Whichever type of thermometer is used, it should be calibrated semi-annually against a National Instrumentation Standards and Technology (NIST) certified thermometer. Note: Them1istors should be checked against a mercury bulb thermometer prior to use and should agree within± 0.5°C. Inspection: All thermometers should be inspected for leaks, cracks, and/or function prior to use. Note: A broken glass bulb-mercury filled thermometer can contaminate samples by the release of mercury vapors. Sample Measurement Procedure: I. Clean the probe end with de-ionized water and immerse into sample. 2. Swirl the thermometer in the sample. 3. Allow the thermometer to equilibrate with the sample. 4. Suspend the thermometer away from the sides and bottom to observe the reading. 5. Record the reading in the log book. Report temperature readings to the nearest ±0.5°C. Note: Always clean the thermometer prior to storage and/or use. Units: Degrees Celsius (°C) or Degrees Fahrenheit(°F) Conversion Formula: °F = (9/5°C) + 32 or °C = 5/9 (°F -32). 28 I I I I I I I I I I I I I I I I I I I 4.3.1.4 Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April I 5, 2004 Dissolved Oxygen (DO) · The most common meters for determining the DO in water are dependent upon electrochemical reactions. Under steady-state conditions, the current or potential can be correlated with DO concentrations. Interfacial dynamics at the ME/sample interface are a factor in probe response and a significant degree or interfacial turbulence is necessary. For precision performance, turbulence should be constant. Meter available: • Membrane/electrode (ME) DO meter ( or equivalent). • YSI Model 95. Inspection: 1. Prior to field use, the membrane of the DO meter should be inspected for air bubbles and/or holes. If air bubbles or holes exist, replace the membrane. 2. The membrane should be checked for dryness. If the membrane is dry, replace and soak it in analyte-free or analyte-free water prior to calibration of the meter. Calibration: I. Air calibrate according to the manufacturer's instructions, either in air saturated water or in a water saturated air environment. 2. The ME meter may be checked and/or calibrated against the Winkler method. Sample Measurement Procedure: I. When making measurements, be sure that the meter stirring apparatus is working. 2. Adjust the temperature and salinity compensators (if equipped). 3. Read the dial to the nearest 0.1 mg/I and record the measurement. To Collect a Sample: I. When possible, measure the DO in-situ with a field probe; otherwise, 2. Collect the sample in a 300-ml BOD bottle and measure the DO with a laboratory type probe. Note: Special care should be exercised to avoid entrainment of atmospheric oxygen or loss of DO. The sample should be collected with a DO Dunker (APHA- type) for depths less than five feet below water surface (BWS). A Kemmerer type sampler is recommended for depths greater than five feet BWS. 3. If an API-IA-type DO Dunker is not available and a shallow depth sample is needed, a bucket may be used to collect a sample of water. A siphon tube should be coiled into the bucket such that the fill end is nearest the bottom. Using a 300-ml BOD bottle, allow the siphoning sample to fill and overflow the bottle for a minimum of three volumes. 4. If a Kemmerer sampler is used, the BOD sample bottle should be filled to overflowing by inserting the outlet tube of the sampler to the bottom of the bottle. The tube should be withdrawn slowly as the bottle is allowed to overflow three times its volume. Care 29 I I I I I I I I I I I I I I I I I I I Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 must be exercised to prevent turbulence or the formation of bubbles when filling the bottle. Duplicate analyses should agree within± 0.1 mg/I. Units: Units are reported in mg/I. Limitations: • • • Dissolved inorganic salts are a factor with the performance of DO probes. Note: The presence of inorganic salts must be determined. Reactive gases which pass through the ME probes may interfere with the DO analysis. For example, chlorine will depolarize the cathode and cause a high probe output. Long-term exposures to chlorine will coat the anode with the chloride of the anode metal and eventually desensitize the probe. Hydrogen sulfide will interfere with the ME probes if the applied potential is greater than the half-wave potential of the sulfide ion. Dissolved oxygen ME probes are temperature sensitive, and temperature compensation is normally provided by the manufacturer (see manufacturers instructions). 4.3.1.5 Oxidation/Reduction Potential (ORP) The Oxidation/Reduction (redox) potential of groundwater is a measure of electron activity and is an. indicator of the relative tendency of a solution to accept or transfer electrons. Redox reactions in groundwater are usually biologically mediated and therefore, the redox potential of a groundwater system acts upon and influences rates of biodegradation. Meters available: • Oakton meters (or equivalent) are typically used for measuring conductivity. • Horiba U-10 or U-22 • Digi-sense Model 5938-00 Calibration: The meter should be calibrated in accordance with the manufacturer's instructions. A two-point standard should be used to insure the accuracy of the meter. Redox measurements may be affected by aeration; therefore, use of a flow through chamber is recommended. I. Check and record the temperature of the standard solutions. 2. Rinse the probe with analyte-free water before immersing it in the standards solution. 3. Immerse the probe in the standard solution and record the reading. Note: If the meter is not accurate to within± 10% of the standard, correct the problem before proceeding. 30 I I I I I I I I I I I I I I I I I Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 Sample Measurement Procedure: 1. Collect the sample with minimal turbidity and aeration. 2. Immerse the probe in the sample keeping it away from the sides and bottom of the container. It is important that the entire portion of the probe be wetted by the sample. This is evident when sample water is seen coming out of the small weep hole. 3. Record the results in a log book. 4. Rinse pro be. Units: Units are reported in millivolts (mV). Results should be reported to the nearest ten mV. 4.3.1.6 Turbidity Turbidity is a measurement of suspended solids in groundwater samples and is a general indicator of sample quality and representativeness. Meters available: • HF Scientific Inc. MicroTPI field portable turbidimeter. Calibration: The meter should be calibrated in accordance with the manufacturer's instructions. A four-point standard (0.02 NTU, 10.0 NTU, 100 NTU, 1000 NTU) is used. Follow the manufacturer's instructions in Appendix D. Sample Measurement Procedure: 1. Collect the sample with minimal turbidity and aeration. 2. Fill clean and dry cuvette with 10 ml of sample. Place cap on top of cuvette and rinse thoroughly. 3. Upon completion discard rinse water and repeat twice. 4. Completely fill rinsed cuvette with remaining portion of sample (approximately 15 ml) and cap cuvette. Ensure that outside of cuvette is dry, clean, and free from smudges. 5. Place cuvette in instrument and press down until cuvette snaps fully into the sample well. 6. Index cuvette by holding the index button on meter while rotating cuvette to obtain the lowest reading on display. 7. Release index button to display turbidity. 8. Record the results in a log book. 9. Rinse cuvette with DI water and allow to air dry. Units: Units should be reported in nephelometric turbidity units (NTUs). Results should be reported to the nearest hundredth NTU for low resolution samples. 31 I I I I I I I I I I I I I I I I I n 10 I Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 4.3.2 Fixed Based Analyses Analysis of groundwater samples obtained from the wells at the Site will include fixed- based parameters. Fixed based parameters will be measured for each well sampled through the analysis of groundwater samples including the following: a) Aromatic and Chlorinated hydrocarbons by EPA Method 6230 D, b) Nitrate, c) Dissolved Iron (II), d) Sulfate, e) Methane, ethane, ethene, f) Alkalinity, g) Major cations (RCRA Metals) including Manganese (Mn), h) Chloride, and i) Total organic carbon These analyses will be performed by Environmental Science Corp. of Mt. Juliet, Tennessee, an NCDENR-DWM certified laboratory. The laboratory maintains Certification No. 375 with the NCDENR-DWM and is presently in good standing. Fixed-based analysis for volatile organic compounds will be conducted employing EPA Method 62300, rather than the EPA Method 8260. The EPA 62300 analysis is to be performed in lieu of the EPA Method 8260 due to the lower detection limit available with the 62300 analysis. Use of this analysis will enable greater accuracy in determining the presence or absence of volatile organic compounds. Resulting data will be submitted in a Contract Laboratory Protocols (CLP) data set. 4.3.2.l Sample Containers and Preservatives Sample containers and preservatives for the fixed based parameters outlined in the S&A Plan are presented as follows. 32 I I I I I I I I I I I I I I I I I I Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 G d roun water s ample on amers, I C t . p reservatives, an 0 mi: 1mcs d H Id' T' Parameter Method(s) Cont.

Chemical preservatives will be added to sample containers in advance of sampling by the laboratory. 4.3.2.2 Sample Identification and Designation The method of sample identification used will depend on the type of sample collected. Samples collected for specific field analyses or measurement data will be recorded directly in bound field logbooks or recorded directly on the Chain-of-Custody Record, with identifying information, while in the custody of the samplers. Examples include pH, temperature, and conductivity. Samples collected for laboratory analyses will be identified by using standard, sequentially numbered and traceable, sample tags/labels, which will be attached to the sample containers. The following information shall be included on the sample tag using waterproof, non-erasable ink: • Project number; • Field identification or sample station number; • Date and time of sample collection; • Designation of the sample as a grab or composite; • Type of sample (water, wastewater, leachate, soil, sediment, etc.) and a very brief description of the sampling location; 33 I I I I I I I I I I I I I I I 0 Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 • The signature of either the sampler(s) or the designated sampling team leader and the field sample custodian (if appropriate); • Sample preservatives. • Analyses to be performed ( checked on front of tag); and • Relevant comments (such as readily detectable or identifiable odor, color, or known toxic properties). Tags/labels for blank or duplicate samples will be marked "blank" or "duplicate," respectively. This requirement does not apply to blind-spiked or blank samples which are to be submitted for laboratory quality control purposes. Blind-spiked or blank samples shall not be identified as such. This identifying information shall also be recorded in the bound field logbooks and on the Chain-Of-Custody Record. 4.3.2.3 Sample Chain-of-Custody Documentation Chain-of-custody procedures will comprise the following elements; I) maintammg sample custody and 2) documentation of samples for evidence. To document chain-of- custody, an accurate record must be maintained to trace the possession of each sample from the moment of collection to its introduction into evidence. A sample or other physical evidence will be in custody if it is: • In the actual possession of an investigator. • In the view of an investigator, after being in their physical possession. • In the physical possession of an investigator and then secured to prevent tampering. • In a designated secure area. Chain-of-Custody (COC) forms will be provided by the laboratory. Each COC will be separately numbered for each ten (I 0) or less samples noted on the document. COC records will bear: • Project name ("NCSU-Lot 86"). • Sampler Name and Signature. • Point of Contact and Phone Number. • Client Address. Sample information documented on the COC will include: • Sample IDs. • Sampling Dates and Times. • Sample Matrix. • Sample Preservatives. • Notation as to whether the samples were filtered. 34 I I I I I I I I I I I I I I I n n D Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Site Version 1.0 April 15, 2004 • Number of sample containers. • Requested fixed-based analyses. Additional information related to the groundwater samples will be included in the "Remarks/Comments" section of the COC. Further information related to Sample Control, Field Records and Document Control are available in Section 3 of the EPA Region IV EISOPQAM, a copy of which is presented in Appendix F. 4.3.2.4 Sample Storage and Transport Sample shipments for the project will occur as necessary to maintain established holding times associated with the fixed-based sample analyses. Samples will be packed on ice subsequent to collection, and will be transported from the Site to the laboratory by either sampling or laboratory personnel. As per Chain-of-Custody requirements, all samples transported to the laboratory will be identified in accordance with 4.3.2.2 and 4.3.2.3. Subsequent to the collection of a sample from any given location (well), each container will be placed on ice in a cooler within minutes of collection. Samples will be secured in coolers with a sufficient amount of ice to ensure proper preservation, and shall, if necessary, be secured within the cooler(s) utilizing bubble wrap or foam packing, at the discretion of the sampling personnel or the laboratory. Care will be taken to ensure that no samples reach a temperature that will cause the sample(s) to freeze. 5.0 REFERENCES Brown & Caldwell, June 1994, Remedial Investigation Report: NCSU Lot 86 Site.

HAZARD IDENTIFICATION EMERGENCY OVERVIEW: Benzene is a colorless, flammable, toxic liquid with a characteristic aromatic odor. Benzene is a confirmed human cardnogen and a possible human mutagen. Inhalation of vapors of Benzene can cause serious, pem,anent damage to the· blood system. Skin and eye contact can be irritating. This liquid is very flammable; vapors are heavier than air and may travel long distances to source of ignition and flashback. If involved in a fire Benzene will decompose to produce toxic gases (e.g., carbon monoxide, carbon dioxide, irritating aldehydes and , ketones). Persons responding to fires or emergencies involving Benzene must have adequate fire protection and wear oersonal orotective equipment to protect aqainst the siqnificant health hazards nosed by Benzene. SYMPTOMS OF OVEREXPOSURE BY ROUTE OF EXPOSURE: Benzene is a serious poison by all routes of exposure. The symptoms HAZARDOUS MATERIAI.INFORMATlON of each route of exposure are described below.

There are reports that exposure to low levels (10 ppm) over an extended time period (24 weeks) of Benzene vapors can damage the bone marrow and blood systems. This damage can result in the development of serious health disorders (including anemia and leukemia). Adverse effects on the immune system have also been reported. Refer to ~Other Health Effects·· in this section for further information. CONTACT WITH SKIN or EYES: Contact with the skin can cause irritation and redness. Repeated or prolonged contact can also cause dermatitis, resulting in dry, itchy, cracked skin .as Benzene is a defatting agent, removing oils from the skin. Contact with the vapors of Benzene and the eyes will be irritating. Direct contact of the liquid with the eyes can cause irritation, pain; prolonged contact may result in tissue damage. SKIN ABSORPTION: Benzene poisoning through skin contact has been reported. although skin absorption is not considered as significant a route of exposure as via inhalation or ingestion. Symptoms of absorption may be similar to those described in "Ingestion". INGESTION: Ingestion of Benzene will cause a burning sensation in the mouth and stomach, nausea, vomiting, excess salivation and vomiting of blood. Benzene is readily absorbed into the body following ingestion exposures. producing symptoms of central nervous system depression and other symptoms similar to those described in "Inhalation". If ingested, Benzene presents a potential asp·1ration hazard. Asp·1ration of even small amounts of Benzene into the lungs can result in immediate pulmonary edema (a potentially fatal accumulr1tion of fluid in the lungs), chemical pneumonitis and hemorrhage of pulmonary tissue. INJECTION: Injection is not anticipr1ted to be a significant route of overexposure for Benzene. If Benzene is ~injectedn (as may occur through punctures by con_taminated, sharp objects). symptoms described in .. lnhalationn can occur.

HAZARD IDENTIFICATION (Continued) OTHER HEAL TH EFFECTS: The chief target organ affected by serious Benzene exposure is the blood and bone marrow system. Chronic Benzene exposure eventually leads to pancytopenia (abnormal decrease of all three formed elements of the blood: hemoglobin. disease-fighting leukocytes and blooc-clotling thrombocytes). followed by thrombocytopenia (problems with the blood-clotting properties of the blood) and anemia. These syndromes can lead to sudden, oveiwhelming infections. After exposure to Benzene, bleeding from the nose, gums, or mucous membranes and development of small bruises can occur. Benzene is a confirmed human carcinogen and can produce forms of leukemia. Direct contact with the liquid with mucous membranes will result in the development of hemorrhagic lesions. HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms. Overexposure to may cause the health effects described on the following page. ACUTE: Acute inhalation overexposure to Benzene will initially act as a narcotic, possibly leading to coma in extreme cases. Following exposure to high con_centrations. victims may be unconscious, and if exposure continues, death can follow from respiratory failure and circulatory collapse. Contact with the skin can cause irritation and dermatitis. Contact with the eyes·is irritating, causing burning and watering of the eyes. Ingestion of Benzene will cause gastric distress, hemorrhage and possible severe depression of the central nervous system. Aspiration of Benzene into the lungs, following ingestion, can result in severe damage to the lungs; death may result. CHRONIC: Chronic exposure to Benzene causes serious damage to the health by all routes of exposure. Chronic oral and inhalation exposure causes severe effects on the blood system, including damage to the bone marrow, leading to a decrease in production or changes to the cells of hemoglobin, hematocrit, red and white blood cells. Effects can occur with an exposure level as low as 10 ppm for 24 weeks. Benzene also causes harmful changes to the iriimune system, decreasing the prOOuction of mature 8-and T-white bloOO cells. Benzene is a confirmed human carcinogen, which can prOOuce Hodgkin's Disease, leukemia and lymphomas by inhalation. Human mutation data are reported for Benzene. See Section 11 (Toxicological Information) for further inform.:1tion. Symptoms of chronic exposure by most routes can be delayed for months to years after exposure hr1s ceased. TARGET ORGANS: Respiratory system, central nervous system, blood and immune systems, bone marrow, heart, liver, kidneys, skin, eyes, and reproductive system. PART II What should I do if a hazardous situation occurs? 4. FIRST-AID MEASURES RESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF EXPOSURE TO BENZENE WITHOUT ADEQUATE PERSONAL PROTECTIVE EQUIPMENT. If necessary, a Self-Contained Breathing Apparatus should be worn. INHALATION: If vapors, mists, or sprays of Benzene are inhaled, remove victim to fresh air. Only trained personnel should administer supplemental oxygen and/or cardio-pulmonary resuscitation if necessary. Remove or cover gross contamination to avoid exposure to rescuers. SKIN EXPOSURE: If Benzene contaminates the skin, Immediately begin decontamination with running water. Minimum flushing is for 15 minutes. Remove exposed or contaminated clothing, taking care not to contr1minate eyes. Victim must seek medical attention if any adverse reaction occurs. EYE EXPOSURE: If Benzene or its vapors enter the eyes, open victim's eyes while under gentle running water. Use sufficient force to open eyelids. Have victim "rotl'' eyes. Minimum flushing is for 15 minutes. Victim must seek immediate medical attention. INGESTION: If Benzene is swallowed, CALL PHYSICIAN OR POISON CONTROL CENTER FOR MOST CURRENT INFORMATION. If professional advice is not available, do not induce vomiting. Victim should drink milk, egg whites, or large quantities of water. If vomiting occurs naturally, have victim lean forward to reduce risk of aspiration. Never induce vomiting or give diluents (milk or water) to someone who is unconscious having convulsions, or who cannot swallow. Victims of chemical exposure must be taken for medical attention. Rescuers should be taken for medical attention, if necessary. Physicians should refer to ~Recommendations to Physicians" in Section 11 (Toxicological Information). Take copy of label and MSDS to health professional with victim. BENZENE C,H, MSDS (Oocun~nt • 10621 PAGE 3 OF 11 5.

NFPA RATING FLAMMA.BIUTY 3 2 0 11:1:ACTIVITY OTlifll: UNUSUAL FIRE AND EXPLOSION HAZARDS: Benzene is a Class 18 flammable liquid and presents a serious fire hazard to firefighters. Due to the low flash point, vapors can fom, explosive mixtures with air, at room temperature. When involved in a fire, this material may decompose and See Section 16 for Definition of Ratings produce toxic gases (e.g., carborl monoxide, carbon dioxide, irritating aldehydes and ketones). The vapors of Benzene are heavier than air and may spread long distances: distant ignition and flash-back are possible. Benzene can float on water; therefore, water contaminated with Benzene can spread the flammable liquid and can spread fire. Containers of Benzene, when involved in fire, may rupture or burst in the heat of the fire. Explosion Sensitivity to Mechanical Impact: Not sensitive. Explosion Sensitivity to Static Discharge: Benzene can accumulate static charge by flow or agitation; vapors can be ignited by static discharge. SPECIAL FIRE-FIGHTING PROCEDURES: In the event of fire. cool containers of Benzene with water to prevent failure. Use a water spray or fog to reduce or direct vapors. Water may not be effective in actually extinguishing a fire involving Benzene, due to its low flash point. Stop the leak or discharge, if possible. For small releases, if it is not possible to stop the leak, and it does not endanger personnel, let the fire burn itself out. Incipient fire responders sl1Q_uld wear eye protection. Structural firefighters must wear·Self-Cont;:iined Brer1thing Apparatus and full protective equipnant, including chemical resistant clothing. Large fires should be fought from a distance with an unmanned hose holde_r or monitor nozzles. /f Benzene is involved in a fire. fire runoff water should be contained to prevent possible environmental damage. If necessary, decontaminate fire-response equipment with soap and water solution. For large releases, consider evacuation. Refer to the North American Emergency Response Guidebook (Guide #130) for additional guidance. 6. ACCIDENTAL RELEASE MEASURES SPILL AND LEAK RESPONSE: Evacuate immediate area. Uncontrolled releases should be responded to by trained personnel using pre-planned procedures. Proper protective equipment should be used. In case of a release, clear the affected area, protect people, and respond with trained personnel. Minimum Personal Protective Equipment should be Level B: triple-gloves (rubber gloves and nitrile gloves, over latex gloves), chemical resistant suit and boots, hard-hat, and Self-Contained Breathing Apparatus. Monitor the surrounding area for combustible vapor levels. Combustible vapor levels must be below 10% of the LEL for Benzene (LEL = 1.3%) before personnel are penmitted to enter the area. If necessary. ventilate area. Monitoring should be done for the levels of Benzene and oxygen. Colorimetric tubes are available to detect the presence of Benzene. Levels of Benzene should be below levels listed in Section 2 (Composition and Information on Ingredients) and the atmosphere must have at least 19.5 percent oxygen before personnel can be allowed in the area without Self-Contained Breathing Apparatus. Eliminate all sources of ignition before clean-up operations begin. Use non-sparking tools. Absorb spilled liquid with activated carbon, polypads or other suitable absorbent materi~ls. Prevent material from entering sewer or confined spaces. Decontaminate the area thoroughly. Place all spill residue in an appropriate cont;:iiner and seal. If necessary, decontaminate spill-response equipment with soap and water solution. Dispose of in accordance with Federal, State, and local hazardous waste disposal regulations (see Section 13. Disposal Considerations). THIS IS AN EXTREMELY FLAMMABLE. TOXIC LIQUID: Protection of all personnel and the area must be maintained. All responders must be adequately protected from exposure.

Note: Refer to the OSHA Benzene Slandard (29 CFR 1910.1028) for specific requirements associated with the use of Benzene. The Action Level for Benzene is 0.5 ppm as an 8-hour, time-weighted average. In workplaces where employees are exposed above the Action Level, the OSHA requirements for monitoring, establishment of regulated areas, methods of compliance, respiratory protection, emergency response protocol, medical surveillance, training and record keeping must be followed. STORAGE AND HANDLING PRACTICES: Entrances to regulated areas (as defined by the OSHA Benzene Standard) must be posted with signs which reads as follows: DANGER BENZENE CANCER HAZARD FLAMMABLE-NO SMOKING AUTHORIZED PERSONNEL ONLY All employees who handle this material should be trained to handle it safely. Avoid breathing vapors or mists generated by Benzene. Use in a well-ventilated location. Cylinders of Benzene must be properly labeled. If Benzene is used in other types of containers, only use portable containers and dispensing equipment (faucet, pump, drip can) approved for flammable liquids. Store cylinders of Benzene in a cool, dry location, away from direct sunlight, sources of intense heat, or where freezing is possible. Do not allow area where cylinders are stored to ~xceed 52"C (125°F). Material should be stored in secondary containers, or in a diked area, as appropriate. Store containers away from incompatible chemicals. Keep cont~er tightly closed when not in use. Storage areas should be made of fire.resistant materials. Inspect all incoming containers before storage, to ensure containers are properly labeled and not damaged. Refer to NFPA 30, Flammable and Combustible Liquids Code, for additional infonnation on storage. Empty containers may contain residual flammable liquid or vapors. Therefore. empty containers should be handled with care. Do not expose yempty~ containers to welding touches, or any other source of ignition. SPECIAL PRECAUTIONS FOR HANDLING CYLINDERS: Protect cylinders of Benzene against physical damage. If appropriate, cytinders should be stored in an up•right position. Cylinders should be finnly secured to prevent falling or being knocked over. Cylinders can be stored in the open, but in such cases, should be protected against extremes of weather and from the dampness of the ground to prevent rusting. Never t.::imper with pressure relief devices in valves and cylinders. Electrical equipment should be non.sparking or explosion proof. The following rules are .applicable to situations in which cylinders are being used: Before Use: If appropriate, move cylinders with a suitable hand•trnck. Do not drag, slide or roll cylinders. Do not drop cylinders or pem,it them to strike each other. Secure cylinders firmly. Lertve the valve protection cap in•place until cylinder is ready for use. During Use: Use designated CGA fittings and other support equipment. Do not use adapters. Do not heat cylinder by any means to increase the discharge rate of the product from the cylinder. Use check valve or trap in discharge line to prevent hazardous backflow into the cylinder. Do not use oils or grease on gas•handling fittings or equipment. · After Use: Close main cylinder valve. Replace valve protection cap. Mark empty cylinders ~EMPTY". NOTE: Use only DOT or ASME code containers. Earth-ground and bond all lines and equipment associated with Benzene. Close valve after each use and when empty. Cylinders must not be recharged except by or with the consent of owner. For additional information refer to the Compressed Gas Association Bulletin SB·2 ~oxygen Deficient Atmospheres". PROTECTIVE PRACTICES DURING MAINTENANCE OF CONTAMINATED EQUIPMENT: Follow practices indicated in Section 6 (Accidental Release Measures). Make certain applicalion equipment is locked and tagged- out safely. Always use Benzene in areas where adequate ventilation is provided. Decontaminate equipment using soapy waler before maintenance begins. Collect all rins~les and dispose of according to applicable Federal, State, or local procedures. BENZENE C,H, MSDS (Document• 10621 PAGE 5 OF 11 8. EXPOSURE CONTROLS -PERSONAL PROTECTION VENTILATION AND ENGINEERING CONTROLS·. Use with adequate ventilation. Use a mechanical fan or vent area to outside. Where appropriate, use a non-sparking, grounded ventilation system separate from other exhaust ventilation systems. Ensure eyewash/safety shower stations are available near areas where Benzene is used. RESPIRATORY PROTECTION: Maintain exposure levels of Benzene below the levels listed in Section 2 (Composition and Information on Ingredients) and oxygen levels above 19.5% in the workplace. Use supplied air respiratory protection if Benzene levels exceed exposure limits and if oxygen level is below 19.5% or during emergency response to a release of Benzene. If respiratory protection is required, follow the requirements of the Federal OSHA Respiratory Protection Standard (29 CFR 1910.134), or equivalent Slate standards.

TOXICOLOGICAL INFORMATION (Continued) SUSPECTED CANCER AGENT: Benzene is listed as follows: BENZENE: ACGIH-A2 (Suspected Human Carcinogen): EPA-A (Human C;:ircinogen)·. IARC-1 (Carcinogenic to Humans): MAK-A1 (Capable of Inducing Malignant Tumors/Experience with Humans); NIOSH-X (Carcinogen): NTP-1 (Known to be a Carcinogen); OSHA-X {Carcinogen); Cal-OSHA (Carcinogen). IRRITANCY OF PRODUCT: Benzene is irritating to the skin, eyes, and other contaminated tissue. SENSITIZATION OF PRODUCT: Benzene is not known to cause respiratory system or skin sensitization in humans. Cardiac sensitization to stimulants (e.g., epinephrine, ephedrine) is a possible result of severe or chron·1c overexposure. REPRODUCTIVE TOXICITY INFORMATION: Listed below is information concerning the effects of Benzene on the human reproductive system. Mutagenicity: Human mutation data are available for Benzene. These data were obtained from individuals who were exposed at levels which produced changes in the blood system. Embryotoxlcity: Benzene is not reported to cause embryotoxic effects in humans. Teratogenicity: Benzene is not reported to cause teratogenic effects in humans. Teratogenic data are available from clinical studies involving test animals exposed to relatively high doses of Benzene. Fetotoxic effects (e.g., reduced birth weight and/or minor skeletal variations) were observed at exposures above 50 ppm. Reproductive Toxicity: Data on reproductive effects on ovaries and testes are available from clinical studies involving test animals exposed to relatively high doses of Benzene. These data were obtained at doses which caused toxic effects on other organs. A mutagen is a chemical which causes permanent changes to genetic material (DNA) such that the changes will propagate through generational lines. An embryotnxin is a chemical which causes damage to a developing embryo (i.e. within the first eight weeks of pregnancy in humans). b11t the damage does not propagate across generational lines. A ferafogen is a chemical which causes damage to a developing fetus. but the damage does not propagate across generational lines. A reproductive toxin is any substance which interferes in any way with the reproductive process. MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Pre-existing blood system disorders, respiratory conditions, central nervous, liver, kidney, and cardio-vascular conditions may be aggravated by severe or chronic overexposUFe to Benzene. Skin disorders may also be aggravated by exposures to Benzene. • RECOMMENDATIONS TO PHYSICIANS: The following guidelines are derived from "Clinical Toxicology of Commercial Chemical Products" (5th edition, 1984 ). • Check for signs of impending pulmonary edema. • Because of the aspiration hazard, avoid emetic drugs. whenever practical. • For overexposures in which emesis is advisable: If the patient is not drowsy. comatose. or in respiratory difficulty, induce vomiting. If necessary, as an alternative treatment, remove Benzene from the stomach via gastric lavage. One or two ounces of mineral oil may be instilled and left in the stomach at the completion of lavage. • Avoid epinephrine because of its possible adverse effect on the sensitized myocardium. Avoid all digestible fats, oils and alcohol., which may promote the absorption of Benzene in the intestinal system. • If eyes or skin are affected, wash thoroughly and apply a bland analgetic ointment. • Because of the possibility of _ventricular fibrillation. monitor the ECG continuously and be prepared to administer external cardiac massage. Refer to the OSHA Benzene Standard [29 CFR 1910.1028; paragraph(i) and Appendix CJ for specific information on Medical Surveillance requirements (i.e. for the general physical exam, medical history, specific tests, and re-examination protocol).

ECOLOGICAL INFORMATION ENVIRONMENTAL STABILITY: Benzene will be degraded over time into other organic compounds. The following environmental data are available for Benzene. BENZENE: Kow = 2.13. Water Solubility= 1791 mg/L. BCF (Anguillajaponica. eels)= 3.5. BCF (C/upea harengus Pallasi, pacific herring)= 4.4. BCF (goldfish)= 4.3. BCF, benzene= 24 (estimated). !f benzene is relP.ased into 1he soit, it will be volatilized near the surface or it will leach to the groundwater. No degradation of benzene (800) was repor1ed in co;use-fillered lake Superior harbor water incubated at 21"C for 12 days. In the marine eco-system, biodegradation occurs from 2 days to 2 weeks in the summer and spring. respectively. The half-life of Benzene in estuarine water was 6 days, as measured by 14C02 produced. Biodegrnd,ilion half-lives of 28 and 16 days were repor1ed in die-away tests for degradation of up lo 3.2 UUL benzene using groundwater and Lester River water. respectively. under aerobic conditions. In a base-rich para- brownish soil, 20 ppm benzene was 24% degraded in one week. 44% in 5 weeks and 47% in 10 weeks. It is not expected lo adsorb to sediment nor bioconcentrate in aquatic organisms. EFFECT OF MATERIAL ON PLANTS or ANIMALS: Benzene may be harmful or fatal to contaminated plant and animal-life (especially if large quantities of Benzene are released). Refer to Section 11 (Toxicology Information). Additional information is available on the effects of Benzene on plants as follows: Benzene is lethal to plants at high concentrations (GT 15600 ppm in air) and short {30 minutes) exposure times. In all species studied recovery was complete upon ~ernoval from exposure to sub-lethal concentrations. Plant growth and rooting is stimulated by aqueous solutions of low benzene concentrations (0.01-0.10 saturated). Aqueous solutions containing high concentrations (0.10-0.15% Benzene) inhibit growth and interfere with metabolism and cell division. EFFECT OF CHEMICAL ON AQUATIC LIFE: Benzene can be harmful or fatal to contaminated aquatic plant and animal life. Benzene floats on water, and can potentially fom, slicks which are capable of creating oxygen-deprived waterways which can contaminate coastal and shore life. The following aquatic toxicity data are available for Benzene.

HAZARD IDENTIFICATION EMERGENCY OVERVIEW: Toluene is a colorless, flammable. toxic liquid, with gasoline-like odor. Inhalation of vapors of Toluene can affect the central nervous system. Symptoms of central nervous system overexposure can include headache, drmvsiness. dizziness, fatigue, nausea and weakness. Skin and eye contact can be irritating. This liquid is very flammable; vapors are heavier than air and may travel long distances to source of ignition and flashback. If involved ln a fire Toluene will decompose to produce toxic gases (e.g., carbon monoxide. carbon dioxide, reactive hydrocarbons and aldehydes). T o1uene is not reactive under normal circumstances. Persons responding to releases of this product must have adequate fire protection for the specific emergency situation. SYMPTOMS OF OVEREXPOSURE BY ROUTE OF EXPOSURE: The most significant routes of occupational overexposure for Toluene are by inhalation, and contact with skin or eyes. The following paragraphs describe symptoms of exposure by route of exposure. INHALATION: Exposures to high concentrations of vapors of Toluene can cause central nervous system effects. Symptoms of central nervous system effects are related to exposure concentrations. The effects associated with various levels of Toluene vapors are as follows: CONCENTRATION SYMPTOMS OF EXPOSURE -50 ppm: Slight drowsiness and headache. 50-100 ppm: Irritation of the nose, throat and respirntory Above 100 ppm: Over 200 ppm: Over 500 ppm: 10,000 ppm (est) tract. Fatigue and dizziness. Symptoms similar to drunkenness, giddiness, numbness. and mild nausea. Mental confusion and incoordination. loss of appetite, a bad taste. At this concentration Toluene causes visual disturbances and further depression of the central nervous system which can result in unconsciousness and death. In an industr\al setting, the most serious overexposures have occurred when vapors of Toluene have accumulated in small, confined spaces or other poorly-ventilated areas. Liver and kidney damage as well as disturbances to the heart have been reported from overexposure to HAZARDOUS MATERIAL INFORMATION SYSlEM (Bll.E) I FLAMMABILl1Y (RED\ I REACTIV11Y !YELLOW\ I PROTECTIVE EQUIPMENT IC I Sec Section 8 t For routirM:"! industrial ;:ipplicatia"ls ,...p. Sec Section 8 See Section 16 for Definition of Ratings vapors of Toluene, in cases of sniffing abuse of glues. Sniffing of glues containing Toluene can lead to the three sets of symptoms, as descriherl helow: I I I I I I I I I I I • Severe muscle weakness leading to limb paralysis, associated with hypokalemia (deficiency of ~tassium in the blood) due to renal tubular acidosis. Cardiac arrhythmias often accompany the hypoka!emia . I • Gastrointestinal complaints, including abdominal pain, nausea, vomiting, and hematemesis (vomiting of blood). • Neuropsychiatric complaints including: a) lethargy, hallucinations, coma, or I b) headache, dizziness, syncope (loss of consciousness due to sudden lack of blood supply to brain), or c) paresthesias (morbid sensations) and peripherril neurop;,ithy (tingling in the extremities), or d) cerebellar ataxia (incoordination of voluntary muscular movements) and other cerebellar signs. The symptoms described above may potentially occur after long-term inhalation overexposures to Toluene in occupational settings, as well as inhalation of fumes from glues. CONTACT WITH SKIN or EYES: Initial contact with the skin can cause mild irritation. Prolonged contad can result in a burning sensation and reddening of the skin. T o!uene is a defatting agent. removing oils from the skin and causing red cracked and dry skin. Prolonged or repeated contact with the skin will cause dermatitis. Very short ex~sure (3-5 minutes) to the eyes of vapors of Toluene c1t a concentration of 300 ppm causes slight irritation. Longer exposures (6-7 hours) to levels above 100 ppm will cause irritation. Contact of the liquid the eyes will be irritating, but will not cause permanent damage. SKIN ABSORPTION: Toluene can be somewhat absorbed through the skin. which may result in irritation at the site of absorption. Symptoms similar to those described for "Inhalation" m.=iy also occur. especially in cases of severe overex~sure. TOLUENE· C,H, MSDS tDocument # 1063) PA~F? ()I: 10 I I I I I I I I I I I I I I I I I I I I I I I I I 3. HAZARD IDENTIFICATION (Continued) INGESTION: Toluene is readily absorbed by the tissues of the digestive system, producing symptoms of central nervous system depression similar to those described in "Inhalation". If ingested. Toluene presents a potential aspiration hazard. The aspiration of Toluene into the lungs can result in severe lung irritr:ition, leading to lung damage; death may result. INJECTION: Injection is not anticipated to be a significant route of oven~xposure for Toluene. If Toluene is "injected" (as may occur through punctures by contamlnated, sharp objects), symptoms described in "Inhalation" can occur. OTHER HEAL TH EFFECTS: Toluene poisoning can lead to anemia and leukopenia (deficiency of blood corpuscle which protects against disease), which, upon biopsy, has shown bone m;:irrow hypoplasia (failure of new bone marrow to mature}. Exposure to other solvents (such as benzene and ethanol) slows the rate of clearance from the body, enhancing the toxicity of Toluene. For further information, see Section 11, Toxicological Information. In rare cases, repeated overexposure to very high concentrations of Toluene has lead to enlargement of the liver. HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms. Overexposure to may cause the health effects described below. ACUTE: Acute inhalation overexposure to Toluene will initially act as a narcotic, possibly leading to coma in extreme cases. Following exposure to high concentrations, victims may be unconscious, and if exposure continues, death can follow from respiratory failure. Contact with the skin can cause irritation and dermatitis. Contact with the eyes is irritating, causing burning and watering of the eyes. Ingestion of Toluene will cause gastric distress and possible severe depression of the central nervous system. Aspiration of Toluene into the lungs, following ingestion can result in severe damage to the lungs; death may result. CHRONIC: In rare cases, chronic poisoning has lead to anemia ,rnd other problems with the blood and bone marrow. Chronic Toluene overexposure may also result in a variety of health problems (e.g., headaches, fatigue, loss of coordination, memory loss, and optic nerve disorders). See Section 11 (Toxicology Information) for additional data. TARGET ORGANS: Respiratory system, central nervous systems, heart , kidneys, bone marrow, skin, eyes, reproductive system. and liver. PART II What should I do if a hazardous situation occurs? 4 .. FIRST-AID MEASURES RESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF EXPOSURE TO TOLUENE WITHOUT ADEQUATE PERSONAL PROTECTIVE EQUIPMENT. If necessary. a Self-Contained Breathing Apparatus should be worn. INHALATION: If vapors, mists, or sprays of Toluene are inhaled, remove victim to fresh air. Only trained personnel should administer supplemental oxygen and/or cardio-pulmonary resuscitation if necessary. Remove or cover gross contamination to avoid exposure to rescuers. SKIN EXPOSURE: If Toluene contaminates the skin, immediately begin decontamination with running water. Minimum flushing is for 15 minutes. Remove exposed or contaminated clothing, taking care not to contaminate eyes. Victim must seek medical attention if any adverse reaction occurs. EYE EXPOSURE: If Toluene or its vapors enter the eyes, open victim's eyes while under gentle running water. Use sufficient force to open eyelids. Have victim "roll" eyes. Minimum flushing is for 15 minutes. Victim must seek immediate medical attention. INGESTION: If Toluene is swallowed, CALL PHYSICIAN OR POISON CONTROL CENTER FOR MOST CURRENT INFORMATION. If professional advice is not available, do not induce vomiting. Victim should drink milk, egg whites, or large quantities of water. If vomiting occurs naturally, have victim le<1n forward to reduce risk of aspiration. Never induce vomiting or give diluents (milk or water) to someone who is unconscious, having convulsions, or who cannot swallow. Victims of chemical exposure must be taken for medical attention. Rescuers should be taken for medical attention, if necessary. Physicians should refer to ~Recommendations to Physici<ms" in Section 11 (Toxicological Information). Take copy of label and MSDS to health professional with victim. 5.

NFPA RATING FL.I.MMA!MLITY 3 2 0 REACTIVITY OTHER UNUSUAL FIRE AND EXPLOSION HAZARDS: Toluene is a Class 18 flammable liquid and presents a serious fire hazard to firefighters. When involved in a fire, this material ignite and produces tox·1c gases (e.g., carbon monoxk'Je, carbon dioxide, reactive hydrocarbons and aldehydes). The vapors of Toluene are heavier than air and may spread long distances; distant ignition and flash-back are possible. Toluene can float on water; therefore, water contaminated with this product can spread the flnmmable liquid and can spread fire. Containers of Toluene, when involved in fire. may rupture or burst in the heat of the fire. See Section 16 for Definition of Ratings Explosion Sensitivity to Mechanical Impact: Not sensitive. Explosion Sensitivity to Static Discharge: Toluene can accumulate static charge by flow or agitation: vapors can be ignited by static discharge. SPECIAL. FIRE-FIGHTING PROCEDURES: Eliminate sources of ignition. In the event of fire, cool containers of this product with water to prevent failure. Use a water spray or fog to reduce or direct vapors. Water may not be effective in actually extinguishing a fire involving Toluene. due to its low flash point. Stop the leak or discharge, if possible. For small releases, if it ls not possible to stop the leak, and it does not endanger personnel. let the fire burn itself out. Incipient fire responders should wear eye protection. Structural fire fighters must wear Self-Contained Breathing Apparatus and full protective equipment. Large fires should be fought from a distance with an unmanned hose holder or monitor nozzles. If Toluene is involved in a fire, fire run-off water should be contained to prevent possible environmental damage. If necessary, decontaminate fire-response equipment w·1th soap and water solution. For large releases, consider evacuation. Refer to the North American Emergency Response Guidebook (Guide #130) for additional guidance. 6. ACCIDENTAL RELEASE MEASURES SPILL AND LEAK RESPONSE: Evacuate immediate area. Uncontrolled releases should be responded to by traled personnel using pre-planned procedures. Proper protective equipment should be used. In case of a leak, clear the affected area, protect people, and respond with trained personnel. Minimum Personal Protective Equipment should be Level B: triple-gloves (rubber gloves and nitrile gloves, over latex gloves), chemically resistant suit and boots, hard~hat, and Self-Contained Breathing Apparatus. Monitor the surrounding area for combustible vapor levels. Combustible vapor levels must be below 10% of the LEL for Toluene (LEL = 1.2%) before personnel are pemiitted to enter the area. If necessary, ventilate area. Monitoring should be done for the levels of Toluene and oxygen. Colorimetric tubes are available to detect the presence of Toluene. Levels of Toluene should be below levels listed in Section 2 (Composition and Information on Ingredients) and the atm0sphere must have at least 19.5 percent oxygen before personnel can be allowed in the area without Self-Contained Breathing Apparatus. Eliminate all sources of ignition before clean~up operations begin. Use non-sparking tools. Absorb spilled liquid with activated carbon, polypads or other suitable absorbent materials. Prevent material from entering sewer or confined spaces. Decontaminate the area thoroughly. Place all spill residue in an appropriate container and seal. If necessary, decontaminate spill-response equipment with soap and water solution. Dispose of in accordance w·1th Federal, State, and local hazardous waste disposal regulations (see Section 13, Disposal Considerations). THIS IS A TOXIC, FLAMMABLE LIQUID: Protection of all personnel and the area must be maintained. All responders must be adequately protected from exposure.

Refer to "Teratogenicity" for additional information. Jeratooenicity: Toluene is not reported to cause teratogenic effects in humans. Many studies have been conducted on rats, nice, and rabbits {primarily through inhalation exposure). Toluene did not cause birth defects, but exposures of pregnant rats to concentrations greater than 500 ppm resulted in fetotoxicity effects (e.g., reduced birth weights, delay in bone fomnalion). Reproductive Toxicity: Data on reproductive effects are available from clinical studies involving test animals exposed to relatively high doses of Toluene, A mutagen is a chemical which causes permanent changes to genetic material (DNA) such that the changes wifl propagate through generation lines. An embryotoxin is a chemical which causes damage to a developing embryo (i.e. within the first eight weeks of pregnancy in humans), but the damage does not propagate across generational lines. A teratoqen is a chemical which causes damage to a developing fetus. but the damage does not propagate across generational fines. A reproductive toxin is any substance which interferes in any way with the reproductive process._ MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Pre-existing respiratory conditions, central nervous sy~, liver, kidney, and cardio-vascular conditions may be aggravated by severe or chronic overexposure to this product. Skin disorders may also be aggravated by exposures to Toluene. RECOMMENDATIONS TO PHYSICIANS: The following guidelines are derived from "Clinical Toxicology of Commercial Chemical Products" (5th edition, 1984). • Check for signs of impending pulmonary edema. • Because of the aspiration hazard. avoid emetic drugs. whenever practical. • For ingestion overexposures in which Toluene contains cmother toxic comix>nent and induction of emesls is advisable: If the patient is not drowsy, comatose. or in respiratory difficulty, induce vomiting. If necessary, as an alternative treatment. remove Toluene from the stomach via gastric lavage. One or two ounces of mineral oil may be instilled and left in the stomach at the completion of lavage. • Avoid epinephrine because of its possible adverse effect on the sensitized myocardium. Avoid all digestible fats, oils and alcohol, which may promote the absorption of Toluene in the intestinal system. • If eyes or skin are affected. wash thoroughly and apply a bland analgetic ointment. • Because of the possibility of ventricular fibrillation. monitor the ECG continuously and be prepared to administer external cardiac massage. • In chronic solvent abusers, correct dehydration, acidosis, hypokalemia and hypophosphatemia. Usually toxic signs and symptoms (except those due to neuropathies and to cerebell;ir lesions) disappear within a few days after fluid and electrolyte abnormalities are corrected. BIOLOGICAL EXPOSURE INDICES {BEls}: The following Biological Exposure Indices (BEls) are currently applicable for Toluene.

ECOLOGICAL INFORMATION ENVIRONMENTAL STABILITY: Toluene will be degraded over time into other organic compounds. The following environmental data are available for Toluene. TOLUENE: Koc= 2.73. Water Solubility= 534 mg/L. Biological Hnlf-Life = 0.083 days. Bioconcen!ration Factors = 13.2 (eels, Anguilla japonica); 1.67 (Manila dam (Tapes semidecussata); 4.2 (mussel. Myhlus edulis): 380 (algae. Chorel!a fusca): 90 {golden ide fish). Toluene is rapidly volatilized from wat~r and undergoes moderate biodegradation. The half-life in water is on the order of days to weeks. EFFECT OF MATERIAL ON PLANTS or ANIMALS: Toluene may be hamnful or fatal to contaminated plant and animal- life (especially if large quantities of Toluene are released). Refer to Section 11 (Toxicology lnfomnation) for infomnation on test animals. The following information is available for Toluene's effects on plant-life. STUDY# 1: Suspensions of sunflower leaves were prepared from 3-5 week old plants. Two ml of ·toluene was applied to 5 grams of the fresh sunflower leaves. The rate of electrolyte loss caused by this treatment was 435 (min -1 x E-4). while the rate of electrolyte loss in the control groups ranged from 16-21 (min -1 x E-4). STUDY# 2: Three tomatoes. 20 carrots, and 12 barley seedlings were tested 32, 32. and 14 days after planting. Plants were exposed to 6.4, 12.0, or 24.1 mg/1 Toluene for 1/4, 1/2, 1, and 2 hours. Toluene was observed to toxic at concentrations of 6.4 to 12.0 mg/I after 15 minutes of exposure. Fifteen minutes of exposure at 12 mg/I toluene produced 50. 0. and 60% injury lo fOfTlato. carrot, and barley, respectively. For lethality to occur at 12.0 mg/1, barley required 1 hour, lomalo 2 hours, and carmt over 2 hours. At 6.4 mg/1 toluene, percenlage of injury to bar1ey after a 2-hour exposure was reduced from 100% to 15% (lethal). Toluene entered the plant rapidly through the cuticle and stomata Symptoms of injury induded a darkening of the tips of the youngest leaves. This darkening spread to the older leaves. There was a loss of turgor, with draping stems and leaves. In bright sunlight, chlorophyll was destroyed. STUDY# 3: Toluene was mixed with Lakeland sand or Davidson soil al rates or O ppm, 200 ppm. 2.000 ppm, and 20.000 ppm. The soils were immediately planted with 4 corn, 6 soybean. and fescue seed. Plants harvested al the end of 3 weeks. A 10% yield reduction on the Lakeland soil was evident at 200 ppm for com, 800 ppm in soybe:m ;md 2.000 ppm in fe'.';r.ue. At 2.000 ppm or morn. there was at least 50% or more reduction in the fresh weight of all three crops. There were no visible symptoms of toluene! toxicity above the critical levels. The critical phytotoxic limit on Lakel<ind sand was 200 to 2,000 ppm of toluene v.-hile on the Oavirlson soil the was 2,000 to 20,000 ppm toluene. EFFECT Of CHEMICAL ON AQUA TIC LIFE: Toluene can be hamnful or fatal to contaminated aquatic plant and animal life. Toluene floats on water, and can potentially form slicks which are capable of creating oxygen-deprived waterways which can contaminate coastal and shore life. The following aquatic toxicity data are available for Toluene. ECso (Pimephales prome/as. fathead minnow embryos/larvae/minnows)= 55-72 rng/L/25-36 mg/U26-31 mg/L -96 hours.

EXPOSURE LIMITS IN AIR: ACGIH -American Conference of Governmental Industrial Hygienists, a professional association which establishes exposure limits. TLV - Threshold Limit Value -an airborne concentration of a substance which represents conditions under which it is generally believed that nearly all workers may be repeatedly exposed without adverse effect. The duration must be considered. including the 8-hour Time Weighted Average (TWA), the 15-minute Short Term Exposure Limit. and the instantaneous Ceiling Level (C). Skin absorption effects must also be considered. OSHA -U.S. Occupational Safety and Health Administration. PEL • Permissible Exposure Limit -This exposure value means exactly the same as a TLV. e)(cept that it is enforceable by OSHA. The OSHA Permissible Exposure limits are based in the 1989 PELs and the June. 1993 Air Contaminants Rule (Federal Register: 58: 35338-35351 and 58: 40191). Both the current PELs and the vacated PELs are indicated. The phrase, MVacated 1989 PEL." is placed next to the PEL which was vacated by Court Order. IOLH • lmmedia!ely Dangerous to Life and Health -This level represents a concentration from which one can escape within 30- minutes without suffering escape-preventing or permanent iniury. The OFG • MAK is the Republic of Germany·s Maximum Exposure Level. similar to the U.S. PEL. NIOSH is the National tnshtu1e of Occupational Safety and Health, which is the research arm of the U.S. Occupational Safety and Health Administration (OSHA). NIOSH issues exposure guidelines called Recommended Exposure Levels (RELs).

I I I I I Groundwater Sampling and Analysis Plan North Carolina State University Lot 86 Sampling Site Version 1.0 April 15, 2004 APPENDIXB ST AND ARD FIELD CLEANING PROCEDURES From Appendix B of: US. Environmental Protection Agency November 2001 Region JV Environmental Investigations Standard Operating Procedures and Quality Assurance Manual I I I I I I I I I I I I I I I I I I I I APPENDIX II STANDARD FIELD CLEANING PROCEDURES PERFORMANCE OBJECTIVE: • To remove contaminants of concern from sampling, drilling and other field equipment to concentrations that do not impact study objectives using a standard cleaning procedure. B.1 Introduction Cleaning procedures in this appendix are intended for use by field personnel for cleaning sampling and other equipment in the field. Emergency field sample container cleaning procedures are also included; however, they should not be used unless absolutely necessary. Cleaning procedures for use at the Field Equipment Center (FEC) are in Appendix C. Sampling and field equipment cleaned in accordance with these procedures must meet the minimum requirements for Data Quality Objectives (DQO) definitive data collection. Deviations from these procedures should be documented in the approved study plan, field records, and investigative reports. 1l1ese are the materials, methods, and procedures to be used when cleaning sampling and other equipment in the field. B.1.1 Specifications for Cleaning Materials Specifications for standard cleaning materials referred to in this appendix are as follows: • Soap shall be a standard brand of phosphate-free laboratory detergent such as Liquinox®. Use of other detergent must be justified and documented in the field logbooks and inspection or investigative reports. • Solvent shall be pesticide-grade isopropanol. Use of a solvent other U1an pesticide-grade isopropanol for equipment cleaning purposes must be justified in the study plan. Otherwise its use must be documented in field logbooks and inspection or investigation reports. • Tap water may be used from any municipal water treatment system. Use of an untreated potable water supply is not an acceptable substitute for tap water. • Analyte free water (deionized water) is tap water that has been treated by passing U1rough a standard deionizing resin column. At a minimum, the finished water should contain no detectable heavy metals or other inorganic compounds (i.e., at or above analytical detection limits) as defined by a standard inductively coupled Argon Plasma Spectrophotometer (lCP) ( or equivalent) scan. Analyte free water obtained by other methods is acceptable, as long as it meets the above analytical criteria. ElSOPQAM B - 1 November 2001 I I I I I I I ' ; I I I I I I ' I , I I I D D • Organic/anal ytc free water is defined as tap water that has been treated with activated carbon and deionizing units. A portable system to produce organic/analyte free water under field conditions is available. At a minimum, the finished water must meet the analytical criteria of analyte free water and should contain no detectable pesticides, herbicides, or extractable organic compounds, and no volatile organic compounds above minimum detectable levels as determined by the Region . 4 laboratory for a given set of analyses. Organic/analyte free water obtained by other methods is acceptable, as long as it meets the above analytical criteria. • Other sol vents may be substituted for a particular purpose if required. For example, removal of concentrated waste materials may require the use of either pesticide-grade hexane or petroleum ether. After the waste material is removed, the equipment must be subjected to the standard cleaning procedure. Because these solvents arc not miscible with water, the equipment must be completely dry prior to use. Solvents, laboratory detergent, and rinse waters used to clean equipment shall not be reused during field decontamination. B.1.2 Handling and Containers for Cleaning Solutions Improperly handled cleaning solutions may easily become contaminated. Storage and application containers must be constructed of the proper materials to ensure their integrity. Following are acceptable materials used for containing the specified cleaning solutions: • Soap must be kept in clean plastic, metal, or glass containers until used. It should be poured directly from the container during use. • Solvent must be stored in the unopened original containers until used. They may be applied using the low pressure nitrogen system fitted with a Teflon® nozzle, or using Teflon® squeeze bottles. • Tap water may be kept in clean tanks, hand pressure sprayers, squeeze bottles, or applied directly from a hose. • Analyte free water must be stored in clean glass, stainless steel, or plastic containers that can be closed prior to use. It can be applied from plastic squeeze bottles. • Organic/analyte free water must be stored in clean glass, Teflon®, or stainless steel containers prior to use. It may be applied using Teflon® squeeze bottles, or with t11e portable system. Note: Hand pump sprayers generally are not acceptable storage or application containers for the above materials (with the exception of tap water). This also applies to stainless steel sprayers. All hand sprayers have internal oil coated gaskets and black rubber seals that may contaminate the solutions. B.1.3 Disposal of Solvent Cleaning Solutions Procedures for the safe handling and disposition of investigation derived waste (IDW), including used wash water, rinse water, and spent solvents are in Section 5.15. B.1.4 Equipment Contaminated with Concentrated Wastes Equipment used to collect samples of hazardous materials or toxic wastes or materials from hazardous waste sites, RCRA facilities, or in-process waste streams should be field cleaned before returning from the study. At a minimum, this should consist of washing witl1 soap and rinsing with tap water. More stringent procedures may be required at the discretion of the field investigators. EISOPQAM B-2 November 2001 I I I I I I D I I I I I I I I I B.1.5 Safety Procedures for Field Cleaning Operations Some of the materials used to implement the cleaning procedures outlined in tllis appendix can be harmful if used improperly. Caution should be exercised by all field investigators and all applicable safety procedures should be followed. At a minimum, the following precautions should be taken in the field during tl1ese cleaning operations: • Safety glasses with splash sllields or goggles, and latex gloves will be worn during all cleaning operations. • Solvent rinsing operations will be conducted in the open (never in a closed room). • No eating, smoking, drinking, chewing, or any hand to mouth contact should be permitted during clearling operations. B.1.6 Handling of Cleaned Equipment After field clearling, equipment should be handled only by personnel wearing clean gloves to prevent re-contamination. In addition, tl1e equipment should be moved away (preferably upwind) from the clearling area to prevent recontamination. Iftl1e equipment is not to be immediately re-used it should be covered with plastic sheeting or wrapped in aluminum foil to prevent re-contamination. The area where the equipment is kept prior to re-use must be free of contaminants. B.2 Field Equipment Cleaning Procedures Sufficient clean equipment should be transported to the field so that an entire study can be conducted without the need for field cleaning. However, this is not possible for some specialized items such as portable power augers (Little Beaver®), well drilling rigs, soil coring rigs, and other large pieces of field equipment. In addition, particularly during large scale studies, it is not practical or possible to transport all of the precleaned field equipment required into tlle field. In these instances, sufficient pre-cleaned equipment should be transported to tl1e field to perform at least one days work. 1l1e following procedures are to be utilized when equipment must be cleaned in the field. B.2.1 Specifications for Decontamination Pads Decontamination pads constructed for field clearling of sampling and drilling equipment should meet the following minimum specifications: • The pad should be constructed in an area known or believed to be free of surface contamination. • The pad should not leak excessively. • If possible, tl1e pad should be constructed on a level, paved surface and should facilitate the removal of wastewater. lllis may be accomplished by either constructing the pad with one comer lower than the rest, or by creating a sump or pit in one comer or along one side. Any sump or pit should also be lined. • Sawhorses or racks constructed to hold equipment while being cleaned should be high enough above ground to prevent equipment from being splashed. • Water should be removed from the decontamination pad frequently. • A temporary pad should be lined with a water impermeable material with no seams within the pad. This material should be eitller easily replaced (disposable) or repairable. EJSOPQAM B-3 November 200 I I I I I I I I i I ' i I I I i I I I I I I I I At the completion of site activities, the decontamination pad should be deactivated. The pit or sump should be backfilled with the appropriate material designated by the site project leader, but only after all waste/rinse water has been pumped into containers for disposal. No solvent rinsates will be placed in the pit. Solvent rinsates should be collected in separate containers for proper disposal. See Section 5.15 of this SOP for proper handling and disposal of these materials. If the decontamination pad has leaked excessively, soil sampling may be required. B.2.2 "Classic Parameter" Sampling Equipment "Classic Parameters" are analyses such as oxygen demand, nutrients, certain inorganics, sulfide, flow measurements, etc. For routine operations involving classic parameter analyses, water quality sampling equipment such as Kemmerers, buckets, dissolved oxygen dunkers, dredges, etc., may be cleaned with the sample or analyte-frec water between sampling locations. A brush may be used to remove deposits of material or sediment, if necessary. If analyte-free water is unavailable the samplers should be flushed at the next sampling location with the substance (water) to be sampled, before the sample is collected. Flow measuring equipment such as weirs, staff gages, velocity meters, and other stream gaging equipment may be cleaned with tap water between measuring locations, if necessary. The previously described procedures are not to be used for cleaning field equipment to be used for the collection of samples undergoing trace organic or inorganic constituent analyses. B.2.3 Sampling Equipment used for the Collection of Trace Organic and Inorganic Compounds TI1e following procedures arc to be used for all sampling equipment used to collect routine samples undergoing trace organic or inorganic constituent analyses: 1. Clean with tap water and soap using a brush if necessary to remove particulate matter and surface films. Equipment may be steam cleaned (soap and high pressure hot water) as an alternative to brushing. Sampling equipment that is steam cleaned should be placed on racks or saw horses at least two feet above the floor of the decontamination pad. PVC or plastic items should not be steam cleaned. 2. Rinse thoroughly with tap water. 3. Rinse thoroughly with analytc free water. 4. Rinse thoroughly with solvent. Do not solvent rinse PVC or plastic items. 5. Rinse thoroughly with organic/analyte free water. If organic/analyte free water is not available. equipment should be allowed to completely dry. Do not apply a final rinse with analytc water. Organic/analyte free water can be generated on-site utilizing the portable system. 6. Remove the equipment from the decontamination area and cover with plastic. Equipment stored overnight should be wrapped in aluminum foil and covered with clean, unused plastic. B.2.4 Well Sounders or Tapes I. Wash with soap and tap water. 2. Rinse with tap water. 3. Rinse with analyte free water.

EISOPQAM B - 5 November 2001 I I I I I I I I I I I I I I I I n u n B.3 Downhole Drilling Equipment These procedures arc to be used for drilling activities involving the collection of soil samples for trace organic and inorganic constituent analyses, and for the construction of monitoring wells to be used for the collection of groundwater samples for trace organic and inorganic constituent analyses. B.3.1 Introduction Cleaning and decontamination of all equipment should occur at a designated area (decontamination pad) on the site. The decontamination pad should meet the specifications of Section B.2.1. Tap water (potable) brought on the site for drilling and cleaning purposes should be contained in a pre-cleaned tank A steam cleaner and/or high pressure hot water washer capable of generating a pressure of at least 2500 PSI and producing hot water and/or steam (200°F plus), with a soap compartment. should be obtained. B.3.2 Preliminary Cleaning and Inspection The drill rig should be clean of any contaminants that may have been transported from another hazardous waste site, to minimize the potential for cross-contamination. Further, the drill rig itself should not serve as a source of contaminants. In addition, associated drilling and decontamination equipment, well construction materials, and equipment handling procedures should meet these minimum specified criteria: • All downhole angering, drilling, and sampling equipment should be sandblasted before use if painted, and/or there is a buildup of rust, hard or caked matter, etc., that cannot be removed by steam cleaning (soap and high pressure hot water), or wire brushing. Sandblasting should be performed prior to arrival on site, or well away from the decontamination pad and areas to be sampled. • Any portion of U1e drill rig, backhoe, etc., that is over the borehole (kelly bar or mast, backhoe buckets, drilling platform, hoist or chain pulldowns, spindles, cathead, etc.) should be steam cleaned (soap and high pressure hot water) and wire brushed (as needed) to remove all rust, soil, and other material which may have come from other hazardous waste sites before being brought on site. • Printing and/or writing on well casing, trcmie tubing, etc., should be removed before use. Emery cloth or sand paper can be used to remove the printing and/or writing. Most well material suppliers can supply materials without the printing and/or writing if specified when ordered. • 111e drill rig and other equipment associated wiU1 the drilling and sampling activities should be inspected to insure that all oils, greases, hydraulic fluids, etc., have been removed, and all seals and gaskets are intact with no fluid leaks. • PVC or plastic materials such as tremic tubes should be inspected. Items that cannot be cleaned arc not acceptable and should be discarded. B.3.3 Drill Rig Field Cleaning Procedure Any portion of the drill rig, backhoe, etc., that is over the borehole (kelly bar or mast, backhoe buckets, drilling platform, hoist or chain pulldowns, spindles, cathead, etc.) should be steam cleaned (soap and high pressure hot water) between boreholes.

I I- I I I I I I I I I B.3.4 Field Cleaning Procedure for Drilling Equipment The following is the standard procedure for field cleaning augers, drill stems, rods, tools, and associated equipment. This procedure does not apply to well casings, well screens, or split-spoon samplers used to obtain samples for chemical analyses, which should be cleaned as outlined in Section B-2.3. I. Clean with tap water and soap, using a brush if necessary, to remove particulate matter and surface films. Steam cleaning (high pressure hot water with soap) may be necessary to remove matter that is difficult to remove with the brush. Drilling equipment that is steam cleaned should be placed on racks or saw horses at least two feet above the floor of the decontamination pad. Hollow-stem augers, drill rods, etc., that are hollow or have holes Uiat transmit water or drilling fluids, should be cleaned on the inside with vigorous brushing. 2. Rinse thoroughly with tap water. 3. Remove from the decontamination pad and cover with clean, unused plastic. If stored overnight, the plastic should be secured to ensure that it stays in place. When there is concern for low level contaminants it may be necessary to clean this equipment between borehole drilling and/or monitoring well installation using the procedure outlined in Section B.2.3. B.4 Emergency Disposable Sample Container Cleaning New one-pint or one-quart mason jars may be used to collect samples for analyses of organic compounds and metals in waste and soil samples during an emergency. These containers would also be acceptable on an emergency basis for the collection of water samples for extractable organic compounds, pesticides, and metals analyses. These jars cannot be used for the collection of water samples for volatile organic compound analyses. l11e rubber sealing ring should not be in contact with the jar and aluminum foil should be used, if possible, between U1e jar and the sealing ring. If possible, the jar and aluminum foil should be rinsed with pesticide-grade isopropanol and allowed to air dry before use. Several empty bottles and lids should be sub1nitted to U1e laboratory as blanks for quality control purposes.

To reduce the potential bias caused by the sampling equipment used to obtain the sample. Ground water sampling may be required for a variety of reasons, such as examining potable or industrial water supplies, checking for and/or tracking contaminant plume movementin the vicinity of a land disposal or spill site, Resource Conservation Recovery Act (RCRA) compliance monitoring, or examining a site where historical information is minimal or non-existent but where it is thought that ground water contamination may have occurred. Ground water samples are usually obtained from eithertemporarily or permanently installed ground water monitoring wells. They can also be obtained, however, anywhere ground water is present, such as in a pit or a dug or drilled hole. Occasionally, the ground water source may not be in U1e ideal location to meet a particular objective (e.g., to track a contaminant plume). In that case, either a temporary or permanent monitoring well should be installed. An experienced and knowledgeable person will need to locate the well and supervise its installation so that samples will be represent_ative of the ground water. Additional guidance is given in RCRA Ground-Water Monitoring: Technical Guidance (I) and Chapter 11 of SW-846 (2). The ground water sampling procedures described in this SOP will meet or exceed the requirements of these documents. Ground water sampling procedures can be sub-divided into two areas, purging and sampling, each of which has different goals and objectives. Within the topic of purging, it is necessary, because of the inherently different characteristics of the two types of wells, to address permanent and temporary wells separately. The procedures and techniques which follow in this section reflect these differences. 7.2 Purging 7.2.1 Purging and Purge Adequacy Purging is the process of removing stagnant water from a monitoring well, immediately prior to sampling, causing its replacement by ground water from the adjacent formation, which is representative of actual aquifer conditions. In order to determine when a well has been adequately purged, field investigators should: I) monitor the pH, specific conductance, temperature, and turbidity of the ground water removed during purging; and 2) observe and record U1e volume of water removed. EISOPQAM 7 - I November 2001 I I I I I I I I I I I I I I I I I m I Prior to initiating the purge, the amount of water standing in the water column (water inside the well riser and screen) should be determined. To do this, the diameter of the well should be determined and the water level and total depU1 of the well are measured and recorded. Specific methodology for obtaining these measurements is found in Section 15.5 of this SOP. Once this information is obtained, the volume of water to be purged can be determined using one of several methods. One is U1e equation: V = 0.041 d2h Where: h = depth of water in feet d = diameter of well in inches V = volume of water in gallons Alternatively, the volume may be determined using a casing volume per foot factor for the appropriate diameter well, similar to U1at in Table 7.2.1. The water level is subtracted from Ule total depth, providing the length of the water column. Tilis length is multiplied by the factor in the Table 7.2.1 which corresponds to Ule appropriate well diameter, providing the amount of water, in gallons, contained in the well. Other acceptable methods include the use of nomographs or other equations or formulae. With respect to volume, an adequate purge is normally achieved when three to five times the volume of standing water in the well has been removed. The field notes should reflect the single well volume calculations or determinations, according to one of Ule above methods, and a reference to the appropriate multiplication ofUlat volume, i.e., a minimum three well volumes, clearly identified as a purge volume goal. With respect to the ground water chemistry, an adequate purge is achieved when the pH, specific conductance, and temperature of the ground water have stabilized and the turbidity has either stabilized or is below 10 Nephelomelric Turbidity Units (NTUs) (twice the Primary Drinking Water Standard of 5 NTUs). Although ten NTUs is normally considered the minimum goal for most ground water sampling objectives, I NTU has been shown to be easily achievable and reasonable attempts should be made to reach Ulis level. Stabilization occurs when pH measurements remain constant within 0.1 Standard Unit (SU), specific conductance varies no more that IO percent, and the temperature is constant for at least three consecutive readings. There are no criteria establishing how many sets of measurements are adequate for the determination of stability. If the calculated purge volume is small, the measurements should be taken frequently to provide a sufficient number of measurements to evaluate stability. If the purge volume is large, measurements taken every 15 minutes may be sufficient. · If, after three well volumes have been removed, the chemical parameters have not stabilized according to the above criteria, additional well volumes (up to five well volumes), should be removed. If the parameters have not stabilized within five volumes, it is at the discretion of the project leader whether or not to collect a sample or to continue purging. If after five well volumes, pH and conductivity have been stabilized and Ule turbidity is still decreasing and approaching an acceptable level, additional purging should be considered to obtain the best sample possible. The conditions of sampling should he noted in the field log.

In these situations, this generally constitutes an adequate purge and the well can be sampled following sufficient recovery (enough volume to allow filling of all sample containers). It is not necessary that the well be evacuated three times before it is sampled. 1l1c pH, specific conductance, temperature, and turbidity should be measured, during collection of the sample from the recovered volume, as the measurements of record for the sampling event. Attempts should be made to avoid purging wells to dryness. This can be accomplished, for example, by slowing the purge rate. If a well is pumped dry, it may result in the sample being comprised partially of water contained in the sand pack, which may be reflective, at least in part, of initial, stagnant conditions. In addition, as water re-enters a well that is in an evacuated condition, it may cascade down the sand pack or the well screen, stripping volatile organic constituents that may be present and/or introducing soil fines into U1e water column. It is particularly important that wells be sampled as soon as possible after purging. If adequate volume is available, the well must be sampled immediately. If not, sampling should occur as soon as adequate volume has recovered. Equipment Available Monitoring well purging is accomplished by using in-place plumbing and dedicated pumps or, by using portable pumps/equipment when dedicated systems arc not present. 1l1e equipment may consist of a variety of pumps, including peristaltic, large and small diameter turbine (electric submersible), bladder, centrifugal, gear-driven positive d_isplaccmcnt, or other appropriate pumps. 1l1e use of any of these pumps is usually a function of the depth of U1e well being sampled and the amount of water that is to be removed during purging. Whenever the head difference between the san1pling location and the water level is less than the limit of suction and the volume to be removed is reasonably small, a peristaltic pump should be used for purging. Appendix E of this SOP contains the operating instructions for all pumps commonly used during Branch ground water investigations. EISOPQAM 7-3 November 2001 I I I I I I I ' ; ' I ' ' I I I I I I I I g u Bailcrs may also be used for purging in appropriate situations, however, their use is discouraged. Bailcrs tend to disturb any sediment that may be present in the well, creating or increasing sample turbidity. If a bailer is used, it should be a closed-top Teflon® bailer. 7.2.2 Purging Techniques (Wells Without Plumbing or In-Place Pumps) For permanently installed wells, the depth of water and depth of the well should be determined (if possible) before purging. Electrical water level indicators/well sounders can be used for tl1is purpose. It is standard practice to mark the top of casing, providing a point of reference from which these measurements will be consistently made. Field investigators should look for these markings when taking these measurements. Extreme caution should be exercised during this procedure to prevent cross-contamination of tl1e wells. This is a critical concern when samples for trace organic compounds or metals analyses are collected. At a minimum, the well sounding device should be cleaned by washing in a laboratory detergent solution, followed by rinses with tap water and analyte-frce water. After cleaning, it should be placed in a clean plastic bag or wrapped in foil. Purging with Pumps When peristaltic pumps or centrifugal pumps are used, only the intake line is placed into the water column. The line placed into tl1e water should be either standard-cleaned (see Appendix B) Teflon® tubing, for peristaltic pumps, or standard-cleaned stainless steel pipe attached to a hose for centrifugal pumps. When submersible pumps (bladder, turbine, displacement, etc.) are used, the pump itself is lowered into the water column. The pump must be cleaned as specified in Appendix B. Purging with Bailcrs Standard-cleaned (Appendix B) closed-top Teflon® bailers with Teflon® leaders and new nylon rope arc lowered into top of the water column, allowed to fill, and removed. It is critical that bailers be slowly and gently immersed into the top of the water column, particularly during final stages of purging, to minimize turbidity and disturbance of volatile organic constituents. The use of bailers for purging and sampling is discouraged because the correct technique is highly operator dependent. Field Care of Purging Equipment Regardless of which method is used for purging, new plastic sheeting should be placed on the ground surface around the well casing to prevent contamination of the pumps, hoses, ropes, etc., in the event they need to be placed on the ground during the purging or they accidentally come into contact with the ground surface. It is preferable that hoses used in purging that come into contact with the ground water be kept on a spool or contained in a plastic-lined tub, both during transporting and during field use, to further minimize contamination from tl1e transporting vehicle or ground surface. Purging Entire Water Column 1l1e pump/hose assembly or bailer used in purging should be lowered into the top of the standing water column and not deep into the column. lllis is done so tliat the purging will "pull" water from the formation into the screened area of the well and up through tl1e casing so that the entire static volume can be removed. If the pump is placed deep into the water column, the water above tl1e pump may not be removed, and the subsequent samples, particularly if collected witl1 a bailer, may not be representative of the ground water. It is recommended that no more than three to five feet of hose be lowered into the water column. If tl1e recovery rate of the well is faster than U1c pump rate and no observable draw down occurs, tl1e pump should be raised until the intake is witl1in one foot oftl1c top of the water column for tl1e duration of purging. EISOPQAM 7-4 November 2001 I I I I I I I I I I I I I I I I I I I If the pump rate exceeds tl1c recovery rate of the well, the pump will have to be lowered, as needed, to accommodate the draw down. After the pump is removed from the well, all wetted portions of t11e hose and the pump should be cleaned as outlined in Appendix B of this SOP. Careful consideration shall be given to using pumps to purge wens which arc excessively contaminated with oily compounds, because it may be difficult to adequately decontaminate severely contaminated pumps under field conditions. When wens of this type arc encountered, alternative purging methods, such as bailers, should be considered. General Low Flow/Low Stress Method Preference The device with the lowest pump or water removal rate and the least tendency to stress the well during purging should be selected for use. For example, if a bailer and a peristaltic pump both work in a given situation, the pump should be selected because it will greatly minimize turbidity, providing a higher quality sample (Section 7.2.4 contains a description of low flow purging and sampling with a peristaltic pump used in a temporary well). If a Fultz® pump or a Grundfos Redi-Flo2® could botl1 be used, the Redi-Flo2® may be given preference because the speed can be controned to provide a lower pump rate, thereby minimizing turbidity. Low Flow/Low Volume Purging Techniques/Procedures Alternatives_ to the low now purging procedures exist and may be acceptable. The low flow/low volume purging is a procedure used to minimize purge water volumes. The pump intake is placed within the screened interval at tile zone of sampling, preferably, tile zone with the highest flow rate. Low flow rate purging is conducted after hydraulic conditions within the well have re-stabilized, usually within 24 to 48 hours. Flow rates should not exceed the recharge rate of the aquifer. This is monitored by measuring the top of the water column with a water level recorder or similar device while pumping. 111csc techniques, however, arc only acceptable under certain hydraulic conditions and are not considered standard procedures. 7.2.3 Purging Techniques -Wells with In-Place Plumbing Wells with in-place plumbing are commonly found at municipal water treatment plants, industrial water supplies, private residences, etc. Many permanent monitoring wells at active facilities are also equipped witil dedicated, in-place pumps. The objective of purging wells witl1 in-place pumps is tile same as witil monitoring wells witilout in-place pumps, i.e., to ultimately collect a sample representative of the ground water. Among the types of wells identified in this section, two different approaches are necessary. The permanent monitoring wells with in-place pumps should, in all respecL~, be treated like the monitoring well witilout pumps. They generally are sampled.only occasionally and require purging as described for wells without in-place pumps, i.e., 3 to 5 well volumes and stable parameters. In the case of the ot11er types of wells, however, not enough is generally known about the construction aspects of the wells to apply the same criteria as used for monitoring wells, i.e., 3 to 5 well volumes. The volume to be purged in these situations, t11erefore, depends on several factors: whether the pumps arc running continuously or intermittently and whether or not any storage/pressure tanks arc located between tlie sampling point and tl1e pump. The following considerations and procedures should be followed when purging wells witil in-place plumbing under the conditions described. EISOPQAM 7-5 November 200 I I I I I I I I ' I I I I I I I I I I I I Continuously Running Pumps If the pump runs more or less continuously, no purge (0U1cr than opening a valve and allowing it to flush for a few minutes) is necessary. If a storage tank is present, a spigot, valve or 0U1er sampling point should be located between the pump and the storage tank. If not, locate the val vc closest to the tank. Measurements of pH, specific conductance, temperature, and turbidity are recorded at the time of sampling. Intermittently Running Pumps If the pump runs intermittently, it is necessary to determine, if possible, the volume to be purged, including storage/pressure tanks that arc located prior to the sampling location. The pump should then be run continuously until the required volume has been purged. If construction characteristics are not known, best judgement should be used in establishing how long to run the pump prior to collecting the sample. Generally, under these conditions, 30 minutes will be adequate. Measurements of pH, specific conductance, temperature and turbidity should be made and recorded at intervals during the purge and the final measurements made at t11c time of sampling. 7.2.4 Purging Techniques -Temporary Monitoring Wells Temporary ground water inonitoring wells differ from permanent wells because temporary wells are installed in the ground water for immediate sample acquisition. Wells of this typcmayinclude standard well screen and riser placed in boreholes created by hand angering, power angering, or by drilling. TI1ey may also consist of a rigid rod and screen that is pushed, driven, or hanunered into place to the desired sampling interval, such as the Direct Push Wellpoint®, the Geoprobe® and the Hydropunch®. As such, the efforts to remove several volumes of water to replace stagnant water do not necessarily apply in these situations, because generally, stagnant water is non-existent. It is important to note, however, that the longer a temporary well is in place and not sampled, the more appropriate it may be to apply, to the extent possible, standard permanent monitoring well purging criteria to it. In cases where the temporary well is to be sampled immediately after installation, purging is conducted primarily to mitigate U1e impacts of installation. In most cases, temporary well installation procedures disturb the existing aquifer conditions, resulting primarily in increased turbidity. Therefore, the goal of purging is to reduce the turbidity and remove the volume of water in the area directly impacted by the installation procedure. Low turbidity samples in these types of wells are typically and routinely achieved by U1e use of low-now purging and sampling techniques. TI1e following low-flow purging technique using peristaltic pumps has been used routinely to achieve acceptably low NTU values in a variety of temporary monitoring well applications. In purging situations where the elevation of the top of the water column is no greater than approx-imately 25 feet below the pump head elevation, a peristaltic pump may be used to purge temporary wells. Enough tubing is deployed to reach the bottom of the temporary well screen. At the onset of purging, the tubing is slowly lowered to the bottom of the screen and is used to remove any formation material which may have entered tl1c well screen during installation. This is critical to ensuring rapid achievement of low turbidity conditions. After U1e formation material is removed from the bottom of the screen, the tubing is slowly raised through the water column to near the top of the column. The tubing can be held at this level to determine if the pump is lowering the water level in the well. If not, secure the tubing at U1e surface to maintain tllis pumping level. If the water column is lowered, and the pump is not variable speed, continue to lower t11e tubing as the water column is lowered. If a variable speed peristaltic pump is being used and draw down is observed on initiation of pumping, reduce U1e pump speed and attempt to match the draw down of U1e well. Sustained pumping at U1esc slow rates will usually result in a relatively clear, low turbidity sample. If the draw down stabilizes, maintain that level, however, if it continues to lower, "chase" tl1e water column until tl1e well is EISOPQAM 7-6 November 2001 I I I I I I I I I g I n D I I I I I evacuated. In t11is case, t11c recovered water column may be relatively free of turbidity and can be sampled. It may take several episodes of recovery to provide enough volume for a complete sample. With many of the direct push sampling techniques, purging is not practical or possible, therefore, no purging is conducted. TI1c sampling device is simply pushed to the desired depth and opened and the · sample is collected and retrieved. 7.2.5 Investigation Derived Waste Purging generates quantities of purge water or investigation derived waste (IDW), the disposition of which must he considered. What is appropriate for the disposition of the water is, in part, dependent on the nature of the investigation. If the IDW is generated at a RCRA facility, it will generally be contained and disposed on site in an on-site treatment facility. IDW generated during Superfund or other investigations may, at the discretion of the field project leader or the program manager (remedial project manager), be discharged to the ground, away from the well, or be containerized for later disposal or other appropriate action. 7:3 Sampling Sampling is the process of obtaining, containerizing, and preserving the ground water sample after the purging process is complete. Non-dedicated pumps for sample collection generally should not be used. Many pumps are made of materials, such as brass, plastic, rubber, or other elastomer products which may cause chemical interferences with the sample. Their principle of operation may also render them unacceptable as a sample collection device. The pump may be turbine driven, which may release volatile organic constituents. It is recognized that there are situations, such as industrial or municipal supply wells or private residential wells, where a well may be equipped with a dedicated pump from which a sample would not normally be collected. Discretion should always be used in obtaining a sample. 7.3.1 Equipment Available Because of the problems with most pumps described in the preceding paragraph, only three devices should he used to collect ground water samples from most wells. These are the peristaltic pump/vacuum jug assembly, a stainless steel and Teflon® bladder pump, and a closed-top, Teflon® bailer. Other monitoring equipment used during sampling includes water level indicators, pH meters, thermometers, conductivity bridges, and nephelometers (turbidity meters). 7.3.2 Sampling Techniques -Wells Wit11 In-Place Plumbing Samples should be collected following purging from a valve or cold water tap as near to the well as possible, preferably prior to any storage/pressure tanks that might be present. Remove any hose that may be present before sample collection and reduce the flow to a low level to minimize sample disturbance, particularly with respect to volatile organic constituents. Samples should be collected directly into t11e appropriate containers (see Standard Sample Containers, Appendix A). It may be necessary to use a secondary container, such as a clean 8 oz. sample jar or a stainless steel scoop, to obtain and transfer samples from spigots with low ground clearance. Also, refer to the Potable Water Supply discussion in Section 2.2. All measurements for pH, specific conductance, temperature, and turbidity should be recorded at the time of measurement. 7.3.3 Sampling Techniques -Wells without Plumbing Following purging, samples should be collected using a peristaltic pump/vacuum jug assembly, a Teflon®/stainless steel bladderpuinp, or a closed-top Teflon® bailer. These techniques are described below. EISOPQAM 7-7 November 2001 I I I I I I a I I I I I I I I I I Peristaltic pump/vacuum jug The peristaltic pump/vacuum jug can be used for sample collection because it allows for sample collection without the sample coming in contact with the pump tubing. This is accomplished by placing a Teflon® transfer cap assembly onto the neck of a standard cleaned 4-liter (I-gallon) glass container. Teflon® tubing (¼-inch O.D.) connects the container to both the pump and the sample source. 111e pump creates a vacuum in the container, thereby drawing the sample into the container without it coming into contact with the pump tubing. Samples for volatile organic compound analysis should be collected using a bailer or by filling the Teflon® tube, by one of two methods, and allowing it to drain into the sample vials. The tubing can be momentarily attached to the pump to fill the tube with water. After the initial water is discharged through the pump head, the tubing is quickly removed from the pump and a gloved thumb placed on the tubing to stop the water from draining out. The tubing is then removed from the well and the water allowed to either gravity drain or be reversed, by the pump, into the sample vials. (Note: When reversing the pump, make sure the discharge tubing is not submerged in purge water. This will prevent introducing potentially cross- contaminated purge water into the sample.) Alternatively, the tubing can be lowered into the well the desired depth and a gloved thumb placed over the end of the tubing. This method will capture the water contained in the tubing. It can then be removed from the wen and the water collected by draining the contents of the tubing into the sample vials. Under no circumstances should the sample for volatile organic compound analysis be collected from the content of any other previously filled container. All equipment should be cleaned using the procedures described in Appendix B. Also, refer to the Potable Water Supply discussion, Section 2.2, for additional information. When sampling for metals only, ii is also pennissible lo collect the sample directly from the pump discharge tubing after an adequate purge has been demonstrated. When collecting samples in this manner there are several considerations to be aware of. 111e pump head tubing (silastic, etc,) must be changed after each well and a rinsate blank must be collected of a representative piece of the pump head tubing (only one blank per investigation). Also, precautions must be taken to ensure that the end of tl1e discharge tubing is not allowed to touch the ground or other surface to ensure the integrity of the sample collected in this manner. Bladder Pumps After purging has been accomplished with a bladder pump, the sample is obtained directly from the pump discharge. If the discharge rate of the pump, during purging, is too great, so as to make sample collection difficult, care should be taken to reduce U1e discharge rate at the onset of actual sample collection. This is necessary to minimize sample disturbance, particularly with respect to samples collected for volatile organic compounds analysis. Bailers Wllen bailing, new plastic sheeting should be placed on the ground around each well to provide a clean working area. New nylon rope should be auached to the bailer via a Teflon® coaled stainless steel wire. This coated wire is semi-permanently attached to the bailer and is decontaminated for reuse as U1e bailer is cleaned. The bailer should be gently immersed in the top of the water column until just filled. At this point, the bailer should be carefully removed and l11e contents emptied into l11e appropriate sample containers. 7.3.4 Sample Preservation Immediately after colleclion, all samples requiring preservation must be preserved witll the appropriate preservative. Consult Appendix A for U1e correct preservative for the particular analytes of ElSOPQAM 7-8 November 2001 I I I I I I I I I I I I I I I interest. All samples preserved using a pH adjustment (except VOCs) must be checked, using pH strips, to ensure that U1ey were adequate] y preserved. TI1is is done by pouring a small volume of sample over the strip. Do not place the strip in the sample. 7.3.5 Special Sample Collection Procedures Trace Organic Compounds and Metals Special sample handling procedures should be instituted when trace contaminant samples arc being collected. All sampling equipment, including pumps, bailers, water level measurement equipment, etc., which comes into contact with the water in the well must be cleaned in accordance with the cleaning procedures described in Appendix B. Pumps should not be used for sampling, unless the interior and exterior portions of the pump and the discharge hoses are thoroughly cleaned. Blank samples should be collected to determine the adequacy of cleaning prior to collection of any sample using a pump. Order of Sampling with Respect to Analytes In many situations when sampling permanent or temporary monitoring wells, an adequate purge, with respect to turbidity, is often difficult to achieve. Removal and insertion of equipment after U1e purge and prior to actual sampling may negate the low turbidities achieved during purging and elevate turbidity back to unacceptable levels. For Ulis reason, it is important that special efforts be used to minimize any disturbance of the water column after purging and to collect the aliquot for metals first. Filtering As a standard practice, ground water samples will not be filtered for routine analysis. Filtering will usually only be performed to determine the fraction of major ions and trace metals passing the filter and used for now system analysis and for U1e purpose of geochemical speciation modeling. Filtration is not allowed to correct for improperly designed or constructed monitoring wells, inappropriate sampling methods, or poor sampling technique. When samples are collected for routine analyses and are filtered, such as under conditions of excessive turbidity, both filtered and non-filtered samples will be submitted for analyses. Samples for organic compounds analysis should not be filtered. Prior to filtration of the ground water sample for any reason other than geochemical speciation modeling, the following criteria must be demonstrated to justify the use of filtered samples for inorganic analysis: I. 2. 3. 4. The monitoring wells, whether temporary or permanent, have been constructed and developed in accordance with Section 6. The ground water samples were collected using sampling techniques in accordance with Ulis section, and the ground water samples were analyzed in accordance with US-EPA approved methods. Efforts have been undertaken to minimize any persistent sample turbidity problems. These efforts may consist of the following: • • Redevelopment or re-installation of permanent ground water monitoring wells . Implementation of low flow/low stress purging and sampling techrliques . Turbidity measurements should be taken during purging and sampling to demonstrate stabilization or lack thereof. These measurements should be documented in the field notes. If the ground water sample appears to have either a chemically-induced elevated turbidity, such as EISOPQAM 7-9 November 2001 I I I ;g D I I I I I I I I I I would occur with precipitate formation, or a naturally elevated colloid or fine, particulate-related turbidity, filtration will not be allowed. If filtration is necessary for purposes of geochemical modeling or other pre-approved cases, the following procedures are suggested: 1. 2. Accomplish in-line filtration through the use of disposable, high capacity filter cartridges (barrel-type) or membrane filters in an in-line filter apparatus. The high capacity, barrel-type filter is preferred due to the higher surface area associated with this configuration. If a membrane filter is utilized, a minimum diameter of 142 mm is suggested. Use a 5 µm pore-size filter for the purpose of determining the colloidal constituent concentrations. A 0.1 µm pore-size filter should be used to remove most non-dissolved particles. 3. Rinse the cartridge or barrel-type filter with 500 milliliters of the solute (ground water to be sampled) prior to collection of sample. If a membrane filter is used, rinse with 100 milliliters of solute prior to sample collection. Potential differences could result from variations in filtration procedures used to process water samples for the determination of trace element concentrations. A numberof factors associated with filtration can substantially alter "dissolved'; trace element concentrations; these include filter pore size, filter type, filter diameter, filtration method, volume of sample processed, suspended sediment concentration, suspended sediment grain-size distribution, concentration of colloids and colloidally-associated trace elements, and concentration of organic matter. Therefore, consistency is critical in the comparison of short-term and long-term results.

Bacterial Sampling Whenever wells (normally potable wells) are sampled for bacteriological parameters, care must be taken to ensure the sterility of all sampling equipment and all other equipment entering tile well.

Water and Wastes (8). 7.3.6 Specific Sampling Equipment Quality Assurance Techniques All equipment used to collect ground water samples shall be cleaned as outlined in Appendix Band repaired, if necessary, before being stored at the conclusion of field studies. Cleaning procedures utilized in the field (Appendix B), or field repairs shall be thoroughly documented in field records. 7.3.7 Auxiliary Data Collection During ground water sample collection, it is important to record a variety of ground water related data. Included in the category of auxiliary data are water level measurements, well volume determinations, pumping rates during purging, and occasionally, drillers or boring logs. Titis information should be documented in the field records. Well volume determinations are described in Section 7.2.1. Water Level Measurements Water table measurements from the top of the well casings (referenced to National Geodetic Vertical Datum) in permanent wells, and ground surface elevations in temporary wells should be made to assist in EISOPQAM 7 -10 November 2001 I I I I I I D I I I ' I I I I I I I I detennining the general direction of ground water flow and gradient. TI1e methodology to be used to determine well water levels are given in Section 15.5. Tracer dyes and radioactive and thermal detection methods can be used to determine direction and velocities of flow (9). Also, a study of the general topography and drainage patterns will generally indicate direction of ground water flow. The ground surface elevation and top of casing elevation at U1e wells should be detennined by stand- ard engineering survey practices as outlined in Section 15. Well Pumping Rate -Bucket/Stop Watch Method The pumping rate for a pump can be detennined by collecting the discharge from the pump in a bucket of known volume and timing how long it takes to fill the bucket. The pumping rate should be in gallons per minute. lhis method shall be used primarily with pumps with a constant pump rate, such as gasoline-powered or electric submersible pumps. Care should be taken when using this method with some battery-powered pumps. AF, the batteries' charge decreases, the pump rate also decreases so that pumping rate calculations using initial, high pump rates may be erroneously high. If this method is used with battery- powered pumps, the rate should be re-checked frequently to ensure. accuracy of the pumping rate calculations.

Should any of this solution come In contact with your clothing or skin, wash ii away immediately with plenty of water. Be especially careful not to allow any of the liquid in the DO sense~ to gel in your eyes. The Dissolved-Oxygen (DO) sensor has a delicate membrane that can easily be ruptured. For safety's sake, the U-1 O Is shipped to you with the DO sensor packed separately. You should insert the DO sensor when you unpack your U'1 o unit. 1. Make sure that the DO sensor has the correct O-ring, as shown. 2. First, fit the DO sensor lightly Into Its socket, and then put on the probe guard to align it correctly. 3. Then, tighten the DO sensor securely to the probe body. When doing this, be especially careful not to damage the membrane, which is located In the front of the DO sensor. 0-ring--~ DO sensor --- ~-e-. \___)>/ Reference sensor --· Probe guard ll!!ll!!!!I 11!!1!!!11!!1 ------ Setting up Inserting the battery The_ U-1 O is shipped from the factory with the battery packed separately.

Just turn on the power and place the probe in the sample or water you wish to measure. All six -parameters are measured simultaneously. These parameters may be stored In memory, printed .out, or viewed one-by-one on the LCD readout. For printing and data storage, see the appropriate sections following this one. To view the parameters one-by-one on the readout. use the SELECT Key to toggle the upper cursor through them. . While the U-10 is_ both rugged and precise, the key to accurate measurements is cleanliness and frequent. cilibration. It Is essential to clean the U-10 thoroughly after each measurement, and it is recommended that you re-calibrate your U-1 O as frequently as possible. For best results, you should recalibrate it before each measurement session. Cleaning and calibration procedures are described below In this section and in the following one.

Note the line on the beaker. Fit the probe over the beaker, as illustrated. Note that the beaker is specially shaped to prevent the DO sensor from being immersed in the standard solution. This is because the DO auto•calibration is done using atmospheric air. ! ~ Calibration beaker With the power on, press the MODE Key to put the unit Into the MAINT mode. The lower cursor should be on the AUTO Sub-Mode; if it Is not, use the MODE Key to move the lower cursor to AUTO. · With the lower cursor on AUTO, press the ENT Key. The readout will show C Al. Walt a moment, and the upper cursor will gradually move across the four auto- calibration parameters one-by-one: pH, COND, TURB, and· DO. When the calibration Is complete, the readout will br'1efly show E,,d and then will switch to the MEAS mode. The upper cursor will blink while the auto-calibration is being made. When the auto-calibration has stabilized, the upper cursor will stop blinking. ------ f~:/t ;ili§i:f::::::; •:· ;::.;~::·,;:.-~f-:::,::::; :;, .

Wash the probe thoroughly with tap water. Be sure to flush off all of sample solution from the probe. Storing the U-10 for brief periods, I.e., about 1 week or Jess: Fill the calibration·beaker with tap water and fit the probe over it. For longer storage The pH sensor must always be kept moist. Fill the small rubber cap with water and use it to cover the pH sensor. The KC! internal solution In the reference sensor may seep out overtime. Place vinyl tape around the O-ring portion to prevent this. If you are going to store the U-10 for a prolonged period without using it, remove the battery from the main unit. , -~t~J }t.·:~ ------ .. ... •.. . _.!:~i~/it:.:.-:: > '· .:_ .. , .. _.;:•::~:-:::::;:i;:-.•.: :-.. ~•'.,"'.•:· -· Section 3 Calibrating the U-1 O The U-1 o Water Checker may be calibrated either manually or automatically. The 4-parameler auto-calibration procedure Is quite handy and should be sufficient for most measurement operatio,ns. Manual calibration for each of the four parameters ls more accurate but, of course, also more time-consuming. ,-.his method should be used for more precise measurement. The manual calibration procedure is explained below in detail, following the description of the auto-calibration procedure. The auto-calibration procedure is extremely simple. The U-10 Water Checker uses just a single solution to do a simultaneous calibration of four parameters: pH. COND. TURB. and DO. Your U-10 comes with a.bottle of sta~dard phthalate pH solution a~d a calibralion beake~ for this purpose. _Auto-calibration procedure ······································• 20 Manual (2-polnl) calibration procedures ..................... 23 pH Calibration ························•··•······················· 24 1.Zero calibration · ·•··· ·•··•·•···· ·· · ·· ·· ·•·· ··•·· · ·· ······ 24 2.Span calibration · ·•· ·· ·· ·••··· ·· · ·· · · ··· ·· ·· · ·· ·· · ·· ·· ··•· 25 COND Calibration •····•···········•·•··················•·•·····•· 26 1.Zero calibration ·········•·•········•···•················· 28 2.Span calibration ··· · ·· ··· ·· · ·· ·· ··· · ·· · ·•· ··· ······· ·· · · · · 29 TURB Calibration :··············································· 30 1.Zero calibration ········································;· 31 2.Span calibration .. : .....•..............................•.. 31 DO Calibration · ··· · · · · ·· ·· · ·· · ·· · ·· ·· · ·· · · ··· ·· ·· · ... · ·· ·· · · ····· 32 1.Zero calibration · ·· ··· ·•· ·· ·•· ·· · ·· ·· ·· · · ·•········ · · ··•·· 33 2.Span calibration ··· ·· ··· ··· ·· ··· ·•· ·· ·· ·· · ····· ······ ·· ··· 33 - · 22 .Auto-calibration .

Salts dissolved in water are separated Into cations and anions. Such a solution Is called an electrolytic solution. An electrolytic solution has the property of allowing the flow of current according to Ohm's law. This property Is referred to Ionic conductivity, since current flow Is due to Ion movement In an electrolytic solution. Metals, on the other hand, allow the flow of current by means of electrons. This property Is called electronic conductivity, which is distinguished from Ionic conductivity. A cube 1 cm on each side, as each shown In Fig, 1, Is used to demonstrate an electrolytic solution. Two electrode plates are placed on opposite sides, and the cube Is filled with a solution. If the resistance between these two electrode plates represented by r{n), the conductivity of the solution L (S.cm:') Is· L-1/r. S stands for Siemens, a unit of measurement of conductance. Fig. 1 Definition of conductivity The most general method for measuring conductivity Is based on the above principle, and Is called the 2-electrtlde method. In this method, to take a measurement, It Is necessary to allow flow of alternating current between the two electrode plates. .1,.

Conductivity iction 6 rm Let ~~ assume that the current, !(A), flows In a sample of conduct1v1ty L -under automatic control of the voltage-applying electrodes-so that the .voltage at the voltage deiectlng- electrodes, £(VJ, remains constant at all times. Theh, the resistance ?f_ the sample, R (_n), across the voltage-detecting electrodes 1s Ra£//. The resistance, R, of the sample fs Inversely proportional to Its conductivity, L. That Is, the conductivity, L, Is proportional to the current, /. Accordingly, calibration of a standar? ~olutlon of known conductivity, Ls, enables calculation of conduct1_v1ty of a sample according to the formula L-Ls(/1/s) from the relation of L:Lsa/:ls. Even In the 4-electrode method, pola,izatlon occurs, since AC curr_en_t flows In the voltage-applying electrodes. The voltage- detect1n~ electrodes are, however, free from the effects of polarlzat1on, since they are separated from the voltage-applying electrodes, and furthermore, current flow Is negllglble. Therefore, the 4-electrode method Is an excellent method to enable measurement of conduct_ivity covering a very high range. · .

The conductivity of a solution depends on Ionic conductivity, described earlier. As the temperature rises, conductivity becomes higher, since Ions begin to move more actively. The temperature coefficient shows the change In % of conductivity per •c, with a certain temperature taken as the reference temperature. This Is expressed In units of %/°C. The temperature coefficient assumes the preml!le that the conductivity of a sample changes linearly according to (emperature. Strictly speaking, with actual samples, however, conductivity changes along a curve. . Furthermore, these curves form different shapes depending on the type of sample. In the ranges of smaller temperature changes, however, samples are said to have the temperature coefficient of 2%/"C; this holds for most samples, except In certal_n special cases. The U-t O Water Checker uses an automatic temperature conversion function to calculate conductivity at 25°C at a temperature coefficient of 2%/"C, based on the measured value of the temperature. Results are displayed on the readout. The U-10's temperature conversion function Is based on the following formula. Lu=Lt / ll+0.02(t-25)1 Where, Lu: t: Lt: Conductivity of solution converted to 25°C {value displ_aled on U-10) Temperature of solution at time of measurement {°C) Conductivity of solution at t (°C) . ---- - == ·--liiili ~-:-.,:,::·,:: . · ....... · .·.,·,,,,:;'..~.-~•V'., tf(': .. ;.. ,t:rr•:iit~-~--~~~~,•,«»'~'H"i~~~~.~~;'fl~ !. ..... , ~ . .-.. ,9;>+?. .~.,..,h.,.,•,,•.z ;a TurtJldity :tion 6 Turbidity {TURB) Prlnclple of measurement _From among several types of turblditfmeasurlng methods available, t~e U-1 O uses the light-absorption-scattering method ~=m~~ ' Irradiation of a beam of light onto a sample brings about sepa:allon of the beam Into (1) the light transmitted by the solution and (2) the light scattered by turbidity components In the sample. In the lig_ht-absorption-scattering method, the Intensity of both transmitted light and the scattered light are measured using se~arate receptors, and the turbidity is obtained based on the ratio of the two. . With the U-10, the light source is a pulse-lighting Infrared- emission diode. The scattered light is measured at a point 30• offset from the light source. This light-absorption-scattering method has several advantages, including the fact that (1) the actual color of the sample fluid has little effect on the · ,:neasurement of tur~idity, (2) fluctuations In light quantity from the light source are easily compensated for, and (3) JI allows the U-1 o to be operated with relatively low-power consumption, Scattered llgh_t rece_P.!~r Light source Transmitted light receptor Sample fluid Fig. 3 Principle of the light-absorption-scattering method 1 WU -.

Kaolin has been the conventional standard solution for mariy years. However, the composition of kaolin solutions often vary depending on the country of origin, and turbidity varies with the degree of purify, Furthermore, there Is often Individual error In preparing the solution. Kaolin Is thus known for brl~glng about very large disparity In measurement results. As a turbidity standard solution; formazine standard solution is now Increasingly being used Internationally. In view of these facts, the U-1 ll-uses the formazine standard solution for its calibration of turbidity.,• In addition, the U· 10 uses NTUs as the unit of turbidity. Other units conventlonaliy used are formazlne degrees and FTUs. When the measurement of turbidity is based on the phenomenon of scattering, the use of NTUs is preferable, and In fact, these are being used increasingly. It should be noted that NTUs used as turbidity units of the formazine standard solution are equivalent to formazlne degrees and to FTUs.

There is a constant relation between conductivity and salinity at certain temperatures. _Therefore, if data on the conductivity and temperature are av~1f~ble, the corresponding salinity Is known. In other words, the salinity measurement of the U-1 o is based on the principle of calculating the salt content, making use of the measured values of conductivity and temperature. Note carefully, therefore, that measured results of all substances whose conductivity is detected are displayed as salinity, For · example, the measured result Is displayed as NaCl concentration, ev_en If In fact the sample component Is, for example, hydrochloric acid (HCI). · Temperature Temperature changes in water have extreme biological effects o~ the life cycles of fish and seaweed, as well as on that of the minute organisms that cleanse lhe water of organic pollutants. Jn general, as the temperature of water increases the amount of oxygen dissolved in the water decreases and there Is a tendency for the amount of pollutants to increase. -. The U-10 uses a thermistor to measure temperature. A thermistor also measures the change in electrical resistance accompany changes In temperature; these changes in resistance. are measured by the thermistor and are used to calculate the · temperature. · This temperature data is used by the U-1 o· In four different · ways: (1) in pH temperature compensation, (2) In conductivity temperature conversion, (3) in the calculallon of salinity and (4) In dissolved-oxygen temperature compensation.

Dissolved-Oxygen 61 Dissolved-Oxygen (DO) Principle of measurement The "DO" referred to here means the concentration of oxygen · dissolved in water. Fig. 4 shows the principle of measurement using a DO sensor. Cathode (silver) .... - Fig. 4 -+ Current __:, Anode (lead) . , -Alkaline electrolyte . -Oxygen-permeable membrane Principle of DO sensor A noblB'.metat' (silver) is filled closely to an oxygen-permeable diaphragm to make the cathode: a base metal (lead) is used as the anode. Both are immersed in an alkaline electrolyte with the anode-to-cathode external circuit complete. Oxygen diffusing througl1 the oxygen-permeable membrane causes a reduction reaction at the calhode; this allows flow of current in the external circuit: 02 + 2H20 + 4e· = 40H" At the anode, oxidation reaction occurs as follows: 2Pb = 2Pb2+ + 4e· The current is proportional to the quantity of oxygen diffusing through the oxygen-permeable diaphragm. Accordingly, measuretnent of the current makes the DO in a sample known. The DO measuring method based on this principle is called the membrane-electrode method. This method allows convenient measurement of DO, especially when compared with chemical- analysis methods, which need complicated pre-treatment to eliminate the effects of oxidizing or reducing substances. Section 6 raa_ aa --.. '::;: ::::t~::: 62 Dissolved-Oxygen section 6 DO correction for salinity When a solution and air are in contact and In complete equilibrium (saturated), DO:C[mg/1] in the solutfon, and the oxygen partial-pressure:Ps[MPa] in air are In the following relation:· C = Ps/H H [MPa!(mgll )1 is referred to as Henry's constant, which depends on the composition of the solution. In general, C becomes smaller as the salinity in the solution increases, since H . becomes larger. A DO sensor is intended to detect .Ps In the above expression. Therefore, the DO m·easurement of an aqueous solution containing salt would be in error if the DO electrode were standardized either on alr,saturated pure water or on air. To settle this problem, it is necessary to correct the DO reading based on the salinity of the sample. Conventional DO meters make this salinity correction by inputting a known salinity value. This poses no problems if the salinity of the sample is known. In practice, however, the salinity of the sample is usually nol known, unless measured by a device such as the U-10. Therefore, until now, DO meters have not been practical, even if they were provided with a salinity-correcting function. · The U-1 o is capable of measuring the salinity of a sample and automatically correcting the DO reading for the amount salinity measured in the sample. ------- ....... , .. ~·'.;\:•}:·:·>. · ..

The MEA sensor eliminates the need for stirring in most environmental applications allowing measurement of DO in the field without an external stirring device. It also reduces measurement errors caused by insufficient or inconsistent stirring. The YSI Model 95 has the following features: • Microprocessor control • Minimal stirring dependence • Low maintenance MEA DO probe • Push-button calibration • · Cap membranes for easy membrane replacement • Simultaneous display of temperature and DO in % air saturation or mg/L • Automatic salinity compensation with manual entering of salinity value • Automatic temperature compensation • Data storage for 50 sets of readings with on screen recall • Waterproof case (IP65) The YSI Model 95 has a non-detachable, combination sensor available with cable lengths of 10, 25, 50 or 100 feet. The Model 95D has a detachable cable. The probe utilizes easy to install cap membranes and the probe body has been manufactured with stainless steel to add rugged durability and sinking weight. The silver anode of the MEA DO sensor requires no servicing for up to 10,000 hours (four years) of operation under normal operating conditions (no sulfite contamination). The Model 95' s micro-processor allows the system to be easily calibrated with the press of a few buttons. Additionally, the micro-processor performs a self-diagnostic routine each time the instrument is turned on. The ~If-diagnostic routine provides useful information about the function of the instrument and probe. For a list of these diagnostic codes, see Section 8, Troubleshooting. A probe calibration/storage chamber is built into the instrument case. A small moist sponge in the chamber provides a water-saturated air environment that is ideal for air calibration of the dissolved oxygen probe. This chamber also provides a convenient place to store the probe when the system is not in use. The Model 95 case is waterproof (rated to IP65) allowing operation in the rain without damage to the instrument. Six AA-sized alkaline batteries power the Model 95. A new set of alkaline batteries will provide approximately 150 hours of continuous operation. When batteries need to be replaced, the LCD will display a ''LO BA 'P' message. The YSI Model 95 is designed for use in environmental, aquaculture, and industrial applications where accurate dissolved oxygen and temperature measurements are desired with minimal stirring. YSI Incorporated Model 95 !1 l SECTION 2 PREPARING THE METER 2.1 UNPACKING When you unpack your new YSI Model 95 Handheld Dissolved Oxygen and Temperature System for the first time, compare the packing list with the contents of the shipping box. If there is anything missing or damaged, call the dealer from whom you purchased the Model 95. If you do not know which authorized dealers sold the system to you, call YSI Customer Service at 800-765-4974 or 937-767-7241, and we1! be happy to help you. 2.2 WARRANTY CARD Please complete the Warranty Card and return it to YSI. The warranty card allows the entry of your purchase of this instrument in our computer system. Once your purchase is recorded, you will receive prompt, efficient service if any part of your YSI Model 95 needs repair during the warranty: period. 2.3 BAmRIES There are a few things you must do to prepare your YSI Model 95 for use. First, locate the six AA-sized alkaline batteries that were included. Use a screwdriver or a small coin to remove the thumbscrew on the bottom of the instrument (see figure below). This thumbscrew holds the battery-chamber cover in place. The battery-chamber cover is marked with the words "OPEN" and "CLOSE." NOTE: On some models, the battery cover thumbscrew may be unscrewed by hand (a screwdriver may not be required). Battery chamber cover Thwnb screw YSI Incorporated Model 95 2 I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I Preparing the Meter Section 2 there is a small molded insert inside each of the two battery-chamber sleeves. These labels illustrate the correct way to install the batteries into each sleeve of the battery-chamber. tAUTION: It is very important that ihe batteries be installed ONLY as illustrated. The instrument will not function and may be damaged if the batteries are installed incorrectly. Turn the instrument on by pressing and releasing the ON/OFF button on the front of the instrument. The liquid crystal display (LCD) should come on. Allow a few seconds for the instrument to complete its diagnostic routine. If the instrument does not operate, consult Section 8, Troubleshooting. You may also want to take the instrument into a dark room and with the instrument ON, hold down the LIGHT button. The instrument back light should illuminate the LCD so that the display can be easily read. 2.4 CALIBRATION/STORAGE CHAMBER The Model 95 has a convenient calibration/storage chamber built into the instrument's side. This chamber provides an ideal storage area for the probe during transport and extended non-use. If you . look into the . chamber, you should notice a small round sponge in the bottom. Carefully put about IO drops of clean w;i.ter into the sponge. Turn the instrument over and allow any excess water to drain out of the chamber. The wet sponge ·creates a I 00% water saturated air environment for the probe that is ideal for dissolved oxygen calibration. 2.5 HAND STRAP Figure I The hand strap (see figure on previous page) is designed to allow comfortable operation of the Model 95 with minimum effort. If the hand strap is adjusted correctly, it is unlikely that the . instrument will be easily dropped or bumped from your hand. To adjust the hand strap on the back of the meter, unsnap the vinyl cover and pull the two Velcro strips apart. Place your hand between the meter and the strap and adjust the strap length so that your hand is snugly held in place. Press the two Velcro strips back together and snap the vinyl cover. back into place. 2.6 METER CASE The meter case is sealed at the factory and is not intended to be opened, except by authorized service technicians. Do not attempt to separate the two halves of the meter case as this may damage the instrument, break the water-proof seal, and may void the manufacturer's warranty. YSI Incorporated Model 95 3 ! : SECTION 3 PREPARING THE PROBE The YSI Model 95 dissolved oxygen probe is shipped wet with a shipping membrane installed. This protective membrane cap on the probe tip must be removed and replaced with a new membrane cap filled with MEA probe solution before using the probe. Follow the instructions below to install the new membrane cap. 3.1 CHOOSING THE CORRECT MEMBRANE CAP Two different membrane caps are available for the Model 95. The YSI Model 9501 Membrane Cap Kit is supplied with the Model 95. This kit contains six 0.5 mil (.0005") membrane caps and a bottle ofMEA probe solution (KC]). NOTE: YSI 9501 Membrane Caps offer the fastest response to changes in DO and are recommended by YSI for most applications. For conditions with low flow or stagnant water, a 1 mil (.001 ") membrane is available (YSI Model 9502 Membrane Cap Kit). This membrane requires less stirring than the 9501, but has a much slower response. Use this membrane when minimal stirring (<2."/sec) is available. I 3.2 MEMBRANE CAP INSTALIATION WARNING: Use only YSI MEA probe solution in the membrane cap. Any other solution will damage the MEA sensor. To ins4,ll a new membrane cap on your YSI Model 95 dissolved oxygen probe: I. Unscrew and remove the probe sensor guard (see Figure 2 ). 2. 3. 4. 5. Unscrew and remove the old membrane cap. Thoroughly rinse the sensor tip with distilled water. Hold the membrane cap and add 8 to 9 drops of MEA probe solution (about half full). Tap the bottom of the cap with your finger a few times to remove any trapped air bubbles. CAUTION: Do not touch the membrane surface. 6. Screw the membrane cap onto the probe tightly by hand (to prevent leakage of electrolyte). A small amount of probe solution should overflow. 7. Shake off any excess probe solution and rinse the stainless steel thoroughly with distilled water to prevent corrosion. YSI Incorporated Model95 4.

The instrument will activate all segments of the display for a few seconds, which will be followed by a self test procedure which will last for several more seconds. During this power on self test sequence, the instrument's microprocessor is verifying that the system is working properly. If the instrument were to detect a problem, a continuous error message would be displayed. See the section entitled Troubleshooting for a list of error messages. NOTE: It is normal for an error to be displayed for a second or two when the system is first · turned on. 4.2 CALIBRATION Dissolved oxygen calibration must be done in an environment with a known oxygen content. Since the amount of oxygen in the atmosphere is known, it makes an excellent environment for calibration (at 100% relative humidity). The calibration/storage chamber contains a moist sponge to create a 100% water saturated air environment. Before calibrating the YSI Model 95, complete the procedures discussed in the Preparing the Meter and Preparing the Probe sections of this manual. To accurately calibrate the YSI Model 95 you will need to know the following information: • The approximate altitude of the region in which you are located. • The approximate salinity of the samples that you will be measuring. Fresh water has a salinity of approximately zero. Sea water has a salinity of approximately 35 (parts per thousand, ppt). If you are not certain what the salinity of the sample water is, use a YSI Model 30 Salinity-. Conductivity-Temperature system to determine it. l. Ensure that the sponge inside the instrument's calibration chamber is wet. Insert the probe into the calibration chamber. 2. Tum the instrument on by pressing the ON/OFF button. Wait for the dissolved oxygen and temperature readings to stabilize (usually 15 minutes is required after turning the instrument on). If the instrument was already on, press the MODE button until dissolved oxygen is displayed in mg/L or % air saturation. To enter the calibration menu, use two fingers to press and release both the UP ARROW and DOWN ARROW buttons at the . same time (DOWN ARROW slightly ahead). YSI Incorporated Model 95 Figure4 7 'I ; i Operation Section 4 3. The LCD will prompt you to enter the local altitude in hundreds of feet. Use the arrow keys to increase or decrease the altitude. When the proper altitude appears on the LCD, press the ENTER button once. EXAMPLE: Entering the number 12 here indicates 1200 feet. 4. The LCD will prompt you to enter the salinity of the sample(s) that you will be measuring. You can enter any number from Oto 80 (ppt). Use the arrow keys to increase or decrease the salinity setting. When the proper salinity appears on the LCD (zero for fresh water), press the ENTER button. 5. The Model 95 should now display CAL in the lower left of the display, the calibration value should be displayed in the lower right of the display and the current DO reading (before calibration) should be on the main display. Make sure that the DO reading (large display) is stable, then press the ENTER button. The display should read SA VE then should return to the Normal Operation Mode. For best results: • Each time the Model 95 is turned off, re-calibrate before taking measurements. • Calibrate at a temperature within ±10°C of the sample temperature. 4.3 MAKING MEASURMENTS The Model 95 has four modes: ► Dissolved Oxygen % -A measurement of oxygen in_ percent of air saturation (partial pressure). ► Dissolved Oxygen mg/L -A measurement of oxygen solubility in mg/L. ► Recall -Allows previously stored data to be displayed. ► Erase all -Allows ALL previously stored data to be deleted. Temperature is displayed in both dissolved oxygen modes. · NOTE: When you tum the Model 95 off, it will "remember" which DO mode you used last and will return to that mode the next time the instrument is turned on. To change between the Model 95 modes, simply press and release the MODE button. The Model 95 will cycle through the modes as follows: Dissolved Oxygen Dissolved Oxygen Recall -E~se all in o/o with°C ~ in mg/L with •c --.. I YSI Incorporated . Model 95 8 I I I I I I I I I I I I I I I I I I I I I I I I I I I I I n I I I I I I I I I Operation Section 4 4.4 STIRRING It is important to realize that even a small amount of stirring will improve the DO and temperature response times in stagnant water, because the transfer process of heat and oxygen wiU be facilitated by convection. Also, the MEA dissolved oxygen probe is not totally stirring independent due to the consumption of oxygen at the sensor tip during measurement. When taking dissolved oxygen measurements in totally stagnant samples, the probe must be moved through the sample at a rate of 2 inches per second to provide adequate stirring. 4.5 SAVING DATA The Model 95 is equipped-with a non-volatile memory that is capable of storing up to 50 different sets of readings. Non-volatile means that you do not need to worry that your data will be lost due to a power failure or interruption, such as when the batteries are removed. Each set consists of dissolved oxygen in percent, dissolved oxygen in mg/L and temperature. The Model 95 will also assign a site identity number to each set of readings to allow easy review of the data. This feature is useful in situations where transcribing data is difficult or not available. While dissolved oxygen is displayed on the screen (in % or mg/L), depress the ENTER button and hold it for· approximately 2 seconds. The meter will flash SA VE on the display along with the current site identity (I through 50) being used. When all 50 sites are full, the display will flash FULL on the screen. This message will remain on the screen (even after power down) until a button is pushed. Once you have acknowledged the memory is full, any subsequent saved data will begin overwriting existing data starting with site#!. No additional warning will be displayed. 4.6 RECALLING STORED DATA I. To put the Model 95 into the RECALL mode, depress the MODE button repeatedly until "rel" is displayed on the screen along with the site ID number in the lower right comer. 2. Depress the ENTER button to review the last set of data that was saved. The Model 95 will display the dissolved oxygen hi % air saturation and temperature. Another press of the ENTER button will display the dissolved oxygen in mg/L and the temperature. 3. Depress the UP ARROW button to move up YSI Incorporated Model 95 9 Operation Section 4 through the saved sets of data. 4. Depress the DOWN ARROW button to move down through the saved sets of data. 5. When you have finished recalling data, press MODE two times to return to normal operation. NOTE: The Model 95 will recall data as a list. When the UP ARROW is depressed the Model 95 will display the Site ID# for the previously recorded date. For example: If you are reviewing Site ID# 5 and the UP ARROW is depressed the Model 95 will display Site ID#4. If you are reviewing Site ID# 5 and Site ID# 5 was the last set of data stored the DOWN ARROW button will display Site ID# 1. Here is an example of the Model 95 memory. Site ID #1 Site ID #2 Site ID #3 .ikhe UP ARROW button was pressed the Model 95 would display Site ID #2 SiteID#4 SiteID#S 4.7 ERASING STORED DATA 1. To erase the data that is stored in the Model 95's memory, depress the MODE button until the Model 95 displays ErAS on the screen. 2. Depress and hold the DOWN ARROW and ENTER buttons simultaneously for approximately 5 seconds. 3. When the Model 95 has successfully erased data, the display reads DONE for I to 2 seconds. The instrument will automatically change to normal operation after completion and the next saved data will be stored in site ID# 1. ™PORTANT: Using the erase function forever and completely erases data in all 50 site ID's. Do not use the erase function until all recorded data has been transcribed to an archive outside the Model 95.

Press the UP ARROW key to toggle the DO reading between %-air saturation and mg/L. 4.9 DISSOLVED OXYGEN FILTER The Model 95 is equipped with a DO filter to help filter out instability and high frequency noise. This feature is useful when measuring dissolved oxygen in an unstable environment such as a fast moving stream or an aeration tank. The default option for the filter is off. To activate the filter, enter the filter option irenu by pressing both the DOWN ARROW and MODE keys together (V key slightly ahead). Operation procedures: • Press both the _DOWN ARROW and MODE keys together (V key slightly ahead). The current status of the filter is displayed, On or OFF, with a smaller "FIL"· displayed in the bottom right comer of the screen. • Press the UP ARROW or DOWN ARROW key to change the current status· of the filter option. • Press ENTER to confirm the change . . • To abort any changes and exit the filter menu, press the MODE key (instead of ENTER). 4.10 DISPLAY BACKLIGHT At titres it may be necessary to take measurements with the Model 95 in dark or poorly lit areas. To help in this situation, the Model 95 comes equipped with a backlight that will illuminate the display so that it can be easily read. To activate the backlight, press and hold the LIGHT button. The display will remain lit as long as the button is depressed. When you le\ it up, the light goes out to preserve battery life. YSI Incorporated Model 95 11 1'" ':j, ! j . I 'I ' i : I . I . I -, ! SECTION 5 PRINCIPLES OF OPERATION 5.1 MEA ClARK OXYGEN SENSOR I I I I The MEA (microelectrrode array) is a steady-state Clarlc type polarographic (voltammetric) dissolved oxygen sensor. The sensor is made of a silver anode and a gold cathode ( consisting of I 00 I very small electrodes, each measuring approximately 8 micrometers in diameter) and is separated from the measured medium by a semi-penneable Teflon membrane. The small dimensions of each individual micro surface consume a very small amount of oxygen. Large spacing between adjacent I microsurfaces allo~s for minimal overlap of diffusion layers from adjacent cathode surfaces. This design produces the minimal stirring dependence of the MEA probe. The temperature sensing ~ Temperature sensor Anode (silver) ~---MEACathode (gold) Figure 5 element (thermistor assembly) is mounted next to the oxygen sensor vertically (see Figure 1), providing temperature readings for the DO system. The membrane selectively allows oxygen to penneate into the ~nsor; but prevents most interfering molecules and fouling materials from entering. Upon permeating through the membrane, oxygen is reduced at the gold cathode. The current resulting from this reduction is diffusion-limited and is proportional to the partial pressure of oxygen in the sample. The counter reaction is the oxidation of silver at the anode/reference electrode that completes the overall electrolytic reaction in the chloride medium (KCI electrolyte) behind the membrane. These reactions, at the cathode and· the anode, are as follows: YSI Incorporated Cathode reaction: . Anode reaction: 02 + 2Hi<) + 4e-=> 40If Ag+Cr >AgCI+e- Model 95 12 I I I I I I I I I I I I I Ii Ir It I I I I I I I I I I I I i ' I : ! Principals of Operation Section 5 5.2 DO READINGS FROM THE CATHODE REDUCTION The oxygen reduction current is sampled and processed, by the meter, and displayed as either %-air saturation or mg/L. While the parameter of %-air (partial pressure) is independent of temperature and salinity, mg/L (solubility of oxygen) is a function of temperature and salinity. The same %-air reading (same partial pressure) would give a higher mg/L reading at a lower temperature than at a higher temperature. The higher the salinity, the lower the solubility (mg/L) is for the same %-air reading at the same temperature. 5.3 FORMATION OF AgCI AT THE ANODE While the oxygen reduction current passes through the internal circuit to be reported as the DO reading, it also passes through the anode oxidizing the silver and forming a thin layer of silver chloride. Furthennore, the oxidation of silver at the chloride medium provides a stable potential that the cathode potent/al is referenced to (for instance, the polarization potential of the cathode is -1.0 V versus the potential of the Ag/AgCl redox couple at the silver anode). Since the current of the MEA sensor is so small, .there should not be any significant accumulation of AgCl at the anode for 3 to4years. 5.4 FUNCTION OF THE ELECTROLYTE There are two main functions for the electrolyte: 1. Supply the chloride (Cr) to the anode/reference electrode for the counter reaction of the oxygen reduction at the cathode. 2. Provide the ionic conduction of electricity inside the cell, especially in the thin layer between the gold cathode and the membrane. Under normal operating conditions, such as measuring oxygen around 100%-air saturation (8.27 mg/L) at 25°C, the electrolyte should last up to 500 hours. This translates into about 62.5 working days at 8 hours per day operation. The actual electrolyte life, however, may be shorter since, in most environmental applications, membrane fouling determines the life of the electrolyte/membrane. YSI Incorporated Model95 13 1· i i i • , I • SECTION 6 MAINTENANCE OF THE MEA SENSOR 6.1 ANODE SERVICE Warning: Under no circumstances should ammonium hydroxide be used to clean the silver anode. Ammonium hydroxide will permanently damage the condition of the MEA surface. The MEA oxygen sensor is, in principle, the same as the conventional Clark oxygen sensor in that the sensor is made of.a silver anode and a gold cathode, but the cathode is a microelectrode.array. Since the current of the MEA oxygen sensor is so much smaller (on average 100 times smaller) than the current of YSI conventional oxygen sensors, consumption of the silver anode, due to the fonnation of AgCl, is minimal during the lifetime of the probe. There should not be any significant build-up of silver chloride at the surface of the anode for 3 to 4 years, therefore, the anode should not require chemical cleaning. However, if the surface of the silver anode has become fouled, gently wet sand it using 400 grit wet/dry sandpaper, rinse thoroughly with deionized or distilled water and wipe with a wet paper towel until the dark layer is removed. The directions are as follows: Anode Oeaning Procedures (See figure 6) ✓ Rinse the sensor thoroughly after removing the membrane cap. ✓ Use wet 400 grit sandpaper to sand away the top layer of the anode by wrapping the sandpaper around the anode and gently rotating it until the dark layer is removed. ✓ ✓ Rinse the anode thoroughly with deionized or distilled water and wipe with a wet paper towel. Rinse the anode again with deionized or distilled water. Figure6 6.2 CATHODE SERVICE Anode Wet microcloth \ Press lightly against sensor smface Warning: Under no circumstances should the gold cathode surface (the MEA surface) be sanded. Sanding will permanently damage the condition of the MEA surface. If the MEA oxygen sensor exhibits erratic behavior, such as a current rise at a rate of 1 %/hour or very jumpy readings, it can be serviced by buffing. You can use a few light twists against the surface with the wet microcloth mounted on the buffing tool provided in the 9503 reconditioning kit. YSI Incorporated Model 95 14 I I I I I I I I 6 I I I I I I I I I I I I I • ~ I I I I n 0 I I I I I I I Maintenance of the MEA Sensor Section 6 Note: The MEA sensor does not require buffing (cleaning) every time the membrane cap is changed. Under normal operating conditions, the MEA sensor should be buffed no more than two times per year. Cathode Cleaning Procedures ✓ Remove the membrane cap and rinse the sensor thoroughly with deionized or distilled water . ✓ Place the microcloth on the buffing tool (self-adhesive). Wet the microcloth thoroughly with deionized or distilled water. ✓ Twist the buffing tool back and forth three times in opposite directions while lightly pressing the buffing tool against_the sensor surface (see figure 6). ✓ Rinse the sensor surface well with deionized or distilled water after buffing. 6.3 DISSOLVED OXYGEN PROBE PRECAUTIONS Membrane life depends on usage. If the probe is properly maintained, one membrane cap should last two to four weeks depending on how often the probe is used and the type of samples measured. It is recommended that membrane caps not be re-used. 1. To keep the electrolyte from drying out, store the probe in a moist environment, such as the calibration chamber with the wet sponge inside. 2. Erratic readings are a result of loose, wrinkled, damaged, or fouled membranes, or from large (more than 1/4 of the circumference of the probe) bubbles in the electrolyte reservoir. If erratic readings or evidence of membrane damage occurs, you should replace the membrane cap and the KCl solution. The average replacement interval is two to four weeks. 3. If the membrane is coated with oxygen consuming (e.g. bacteria) or oxygen evolving organisms (e.g. algae), erroneous readings may occur. 4. Chlorine, sulfur dioxide, nitric oxide, and nitrous oxide can affect readings by behaving like oxygen at the probe. If you suspect erroneous readings, it may be necessary to determine if these gases are the cause. 5. Avoid any environment that contains substances that may attack the probe materials. Some of these substances are concentrated acids, caustics, and strong solvents. The probe materials that come in contact with the sample include FEP Teflon, stainless steel, epoxy, polyetherimide and the polyurethane cable covering. 6. Do not allow the probe to strike hard objects. The membrane or sensor inside may be damaged. 6.4 PROBE STORAGE For long term storage (4 weeks), remove the membrane cap, thoroughly rinse the MEA sensor with deionized or distilled water and install a new membrane cap filled with MEA probe solution. Store the sensor in a humid environment such as the calibration chamber with the wet sponge inside. Do NOT store the probe dry. YSI Incorporated Model 95 15 SECTION 7 DISCUSSION OF MEASUREMENT ERRORS There are three basic types of dissolved oxygen errors. Type 1 errors are related to limitations of instrument design and tolerances of instrument components. These are primarily the meter linearity and the resistor tolerances. Type 2 errors are due to basic probe accuracy tolerances, mainly background signal, probe linearity, and variations in membrane temperature coefficient. Type 3 errors are related to the operator's ability to determine the conditions at the time of calibration. If calibration is performed against more accurately known conditions, type 3 errors are appropriately reduced. Type 1 Errors A. Meter linearity error: ±0.5% of full scale reading, or ±0.04 mg/1 at 25°C whichever is greater. B. Component and circuitry error: ±0.04 mg/1 Type 2 Errors A. DO errors caused by temperature compensation for measurements at ± !0°C from calibration temperature: ±1 % of 25° C (±0.08 mg/1) B. DO errors caused by temperature measurement errors: A maximum ±0.2°C temperature error is equal to ±0.5% (0.04mg/L at 25°C). Type 3 Errors A. Altitude: The maximum DO error caused by calibrating to altitude in increments of l 00 feet: ±0.18% (< 0.015 mg/1 at 25°C) B. Humidity: Errors occur if calibration is performed at less than l 00% humidity. The worst possible case would be calibration at 0% humidity. The. error varies with the calibration temperature as follows: . Temperature Calibration Error at 0% humidity 0°C 0.09mg/l 10°c 0.14 mg/1 20°c 0.21 mg/1 30°c 0.33 mg/1 40°c 0.50 mg/1 Approximating The Error It is unlikely that the actual error in any measurement will be the maximum possible error. A better error approximation is obtained using a root mean squared (r.m.s.) calculation: r.m.s. error= ±[la2 + lb2 +2a2 + 2b2 + 3a2 + 3b2]" mg/1 NOTE: This calculation is for a near extreme set of conditions. If the probe is calibrated in water-saturated air, then type 3B errors (humidity), the largest error of all types, is virtually eliminated and the maximum possible error is in the order of 0.1 mg/L for the case of calibrating around 25°C.

I CJ • I. 8 m!I mm ;;a lliilli lilii iiiill llliii 4; Calibration Ill Important Information on Meter Calibration When you recalibrate your meter, old pH and conductivity calibration data are replaced on a point by point basis. For example, if you previously calibrated your meter at pH 4.0, 7.0, and 10.0, and yuu recalibrate.at pH 7.0, the meter retains the old calibration data at pH 4.0 and pH 10.0. To completely recalibrate your meter, or when you use a replacement probe., it is best to set the meter to its factory defaults and recalibrate the meter at all points. To reset the meter to it~ factory defa1ts: 1 • \rVhile in Measurement mode, press CAL/MEAS and hold for 3 seconds. 2. The meter will prompt RST in the upper display and CAL in the l.ower display . . See figure 0 3. Press ENTER to reset your meter to its factory defaults. If you do not want to erase existing calibration data, press CAL/MEAS to escape this mode. ,!, For information on how to calibrate your meter: • See section 4.3 on pages 10-11 for pH calibration r • See section 4.4 on pages 12-13 for conductivity calibration • See s~on 4.5 on pages 14-15 for temperature calibration lfJ Preparing the Meter for Calibration ,-,._ ,._ _, ,._ c,qL ~ The pH/conductivity/temperature probe included with thiS meter is designed for use with this meter only. Do not substitute other types of probes or electrodes. For a I'eplacement probe, see the "Accessories" section, page 22. Be sure to remove the protective rubber cap of the probe before calibration or measurement Wet the probe in tap water for 10 minutes before calibrating or taking : rea~ings to saturate the pH electrode surface an~ minimize drift. Wash yo\.lr probe in deionized water after use, and store in pH 4.0 or 7.0 electrode · storage solution. Do not reuse buffer solutions after calibration. Contaminants in the solution can affect the calibration, and eventually the accuracy of the measurements. 9 ID pH_ calibration .. This instrument is c~pable of up to 3-point pH ~alibration tO ensure accuracy across the entire pH range of the meter._You can perform-1-, 2-, or 3-point calibration with standard pH buffers 4.00; 7.00 and 10.00. We recommend that you perform at least a 2-point calibration using standard buffers that bracket (one above and.one be~ow) the expected sample range. You can also perform a 1-point calibration, but make sure that the buffer value is close to the sample value you are measuring. This meter features three preprogrammed pH buffers (pH 4.00, 7.00 and 10.00). The meter automatically recognizes and calibrates to these standard buffer values, which makes pH calibration faster and easier. See pages 22-23 for information on our high-quality Cole-Parmer pH buffers. Calibrating for pH: 1. If necessary, press the MODE key to select p!i mode. The pH indicator appears in the upper right hand comer of the display. 2. Rinse the probe thoroughly with de-ionized water or a rinse solution. Do not wipe the probe; this causes a build-up of eled:rostatic charge on the glass surface. 3. Dip the probe into the calibration buffer. The end of the probe must be completely immersed into the sample. Stir the probe gently to create a homogeneous sample. 4. Press CAUMEAS to enter pH calibration mode. The primary display will show the measured reading while the smaller secondary display will indicate the pH standard buffer solution. See figure 0 NOTE: If using a pH buffer other than pH 7, press the A or T keys to scroll up or down until the secondary display value is the same as your pH buffer value (pH 4.00, 7.00 or 10.00). 10 r CAL -; I l I pH ·I, I I ·,nn pH ~ · .. 1,U,U ATC 4·. i • 5.

A confirming indicator (CON) flashes and disappears. The meter.is now _calibrated at the buffer indicated in the secondary display. Seefi G gure . The secondary display automatically scrolls to the next buffer calibration option. • If you are performing multipoint calibration, go to step 7. • If you are performing one-point calibration, go to step 10. 7. Press the A or T keys to select the next buffer value you want to calibrate (pH 4.00; 7.00 or 10.00). · See figure 8 8. Rinse the probe with <:le•ionized water or a rinse solution, and place it in the next pH buffer. 9. Follow steps 5 to 8 for additional calibration points (up to 3 values). 10. When calibration is complete, press CAUMEAS to return io pH measurement mode. Notes To exit from pH Calibration mode without confirming calibration, DO NOT p~ ENTER in step 6. Press CAL/MEAS instead. If the selected buffer value is not Within . ±0.50 pH frorri the measured pH value: the electrode and buffer icon blink and the ERR annunciator appears in the lower left comer of the display. These indicators also flash if the buffer used is not the same as the buffer value on .the secondary display. f READY ( READY ◄• ~.:.:i ◄·• ~ 1!!!11!!!!!!1· / , CAL I.

The next best method "is to chooSe a calibration solu:. tion value that is approximately½ the full scale value of the measurement range. For example, in the Oto 1999 µS range, use a 1413 µS solu~ion for calibra- tion. See "Sp~cifications", page 21. Preparing the Meter for Conductivity Calibration You can calibrate at one point per range of the meter (a total of up to four cali- bration points). However, only the ranges_ that have been. calibrated have. maximum ±1 % fall-scale conductivity ticcuracy. If a range was not calibrated, the meter automati- cally detects the closest range calibrated and uses that calibratio_n information. To maintain ±1% F.S. accuracy, you need to calibrate your meter a! least once a week if: • you take measurements at extreme temPeratures • you are measuring in conductivity ranges lower than 100 µS To maintain ±1 % F.S. accuracy, you need to calibrate your meter at least once a month if: · • yoll are measuring in mid range solutions, and you wash the celI in deionized water between usages. The conductivity of solution varies gre.itly with temperature. The automatic temperature compensatioh (ATC) fea·ture adjusts. the fluctuations of cOndti.ctivity readings in varying temperatures· to a standard temperature. These cond~ctivity meters feature a temperature coefficient of 2.00% per °C and normalize the readings at 25°C. I Calibrating for Conductivity: 1. Pour out two separate portions of your calibration standard and one of ~eionized water into ~eparate clean containers. 2. If necessary, press the MODE key to select Conductivity Mode. The µSor mS indicator will appear on the right side of the display. 3. Rinse your probe with deionized water, then rinse.the probe in One of the portions of calibz:ation standard. 4. Immerse the probe into the second portion of calibration standard. The meter's autoranging function selects the appropriate conductivity range (four ranges are possible). Be sure to tap the probe to remove air bubbles. Air bubbles will cause"e,rors in calibration. · 12 ----- - 5. Wait for_the reading to stabilize. The READY indicator lights when the reading · is stable. See figure() 6. Press the CAIJMEAS key. The CAL indi- cator appears above the primary display. The primary display shows the measured reading and the secondary display shows · the temperature. See figure 8 7. Press the A or T keys to scroll to the value of your conductivity standard. Press · and hold the A or T keys to scroll faster. The meter automatically compensates for_ temperature differences using a factor of 2.00% per ~C. Seefigureo 8. Press the ENTER key to confirm calibration. Upon confirmation, the CON indicator appears briefly. The meter automatically switches back into Measurement mode. The display now shows the calibrated, tempera- ture compensated conductivity value. s.e figure 8 9. For calibration in other ranges (rnaxiinum: four ranges) repeat steps I through 9 with the appropriate calibration standards. See pages 22-23 for our selection of high-quality Cole-Parmer conductivity cali~ration solutions. Notes To exit from Conductivity Calibration mode without confirming calibration, DO NOT press ENTER in step 8. Press CAL/MEAS instead.

In extreme applications, the probe may we.ir out sooner. Proper care and·mai!lte~ance will help you receive the·maximum probe life and ensure more accurate readiii.gs. · Keep the probe clean. Before use, rinse the probe hvice. For the best-accuracy, soak your probe in electrode storage solution, pH 4.0 buffer, or tap water for at least 5 to 10 minutes before calibration. Gently swirl the probe in the solution while_ you take readings. Tap the probe gently against the bottom and sides of your container to remOve any air bUbbles, which may interfere with accuracy. Clean the probe thoroughly by immersing it in an agitated mild detergent bath. To clean the conductivity ,cell, use a cotton swab soaked in isopropyl alcohol and c;lean the steel pins. Wipe the steel pins with a soft tissue paper. DO NOT wipe the pH· · bulb with tissue·as it may cause static build-up. After cleaning the probe, wash the probe with deionized or tap water before storing it. Recalibrate the meter after cleaning the probe. Store the probe in its cap filled with electrode storage solution. Do.not strike the probe against any hard surface. Do not immerse the probe in o'ily solutions.

I.' I ' ,,, : ~ GENERAL DESCRIPTION This portable, Digital pH Meter is designed with solid state electronics providing highly reliable operation. The _LCD display enables you tci read even under bright ambient conditions. It is designed for pH (manual), millivolt and ORP. determination. OPERATING TIPS For fast response, the glass bulb of the probe should always be kept moist. A rubber cap is supplied with the probe to store a small amount of solution and to cover the glass bulb. Before use, remove the cap. If the cap has been left off and the tip of the probe is dry, dip the probe in KCL solution for 30 minutes or soak in tap water for 2 hours. When the electrode is not in use, replace the cap which should be filled with KCL or equivalent probe storage solution. If a solution is not available, use tap water. NOTE: Do not use distilled or deionized water for storing, under any circumstances. Front Panel Controls The features on the front panel are: 1. ON/OFF key 2. (pH/mV) key 3. SLOPE adjustment 4. Manual temperature adjustment 5. Standardize control 6. pH probe input 7. LCD display 2 pH Calibration Calibration with manual temperature compensation. 1. Press ON/OFF key to turn meter on. 2. Connect the pH probe to the meter. 3. Immerse the probe in buffer 7.00. 4. Press the pH/mV key to select pH. 5. Adjust temp °C control to the temperature of buffer 7.00. NOTE: A separate thermometer is needed to measure the temperature of the buffers. Both buffers should be at the same temperature. 6. Adjust the standardize control to read 7.00 pH on the display. 7. Rinse the probe with distilled water and blot dry. 8. Immerse the probe in the second buffer (4.00 or 10.00). 9. Adjust the temp °C control to the temperature of the second buffer. 10. Allow the reading to stabilize, then adjust the SLOPE control to the value of the second buffer. 11. Rinse the probe with distilled water. Calibration is now complete. OPERATION 1. Push the ON/OFF key to turn the meter on. 2. Push the pH/mV key until the annunciators indicate the desired mode. For pH ·measurement: Rinse the probes with distilled water, then immerse the probe in the solution to be measured. The pH value will stabilize after a few· seconds. Do not rub the bulb as this will cause static build-up on the bulb resulting in faulty readings. · Temperature Compensation Temperature compensation can be set manually by the temperature °C adjustment over a iange of 0° to 100° C. For millivolt or ORP measurement: Press the pH/mV key until the display shows· millivolts. Verify the probe connection, then rinse the probe with distilled water and blot dry. Immerse the probe in the sample to be measured. Allow the displayed reading to stabilize, then take the reading. 3, ';' ,1 Battery Replacement The pH meter uses a 9 volt battery with a life of 2000 hours. If the low battery indicator is on, stop operation and replace the internal battery with a new 9 volt battery. · Cleaning the Probe The glass bulb is the sensitive part of the probe, it should always be kept clean .. Rinse the probe with distilled water after use. Before storage, rinse the probe with tap or distilled water, shake dry and place the probe in the protective cap which should be filled with a KCL solution or equivalent probe storage solution. If KCL or equivalent storage solution is not available, use a 4.00 pH buffer, 7.00 pH buffer or tap water. NOTE: Distilled or deionized water should never be used.

The order in which the measurements are made may be important in some field investigations. The parameters will be discussed in the most applicable order. References for each parameter can be found at the end of the section. Numerous meters/instruments arc commercially available. Some meters are capable of multiple measurements which may include: pH, temperature, conductivity, DO, salinity, and turbidity; therefore, individual meters discussed here are not necessarily the only ones available. However, the setup and use of all instruments should follow a basic format to ensure consistency. Quality Control All equipment should be maintained and operated in accordance with the manufacturer's instructions. Regardless of the meter used, it should be properly calibrated or verified prior to use. All field meters with thermistors are verified against a National Institute of Standards and Technology (NIST) traceable thermometer, the Hanna Instruments ChcckTemp I or equivalent, at least semi-annually. Titis includes, but is not limited to, the pH, conductivity, and DO meters. These verification checks are documented in a logbook and maintained at the Federal Equipment Center (FEC). Labels arc placed on the field instruments to indicate when the next verification check is required. Additionally, the CheckTcmp 1 is NIST Certified at least annually and documented. The thermistors for all pH, conductivity, and DO meters should be verified in the field with one of the NIST traceable Fisher brand stem-type digital thermometers. All data for U1e field verifications should be documented in the inspector's logbooks. The turbidimeter is calibrated with Formazin Primary Standards semi-annually and a record of the calibration is maintained on file at the FEC. The Gclex secondary standards will be standardized against U1e Formazin Primary Standards by the FEC. 111c turbidimcter should be verified with U1e Gclex secondary standards before each use. These verifications should be documented in the inspector's logbook. Standard Methods requires that the conductivity meter's electrode cell be verified by comparing against a laboratory meter wiU1 a platinum-electrode type conductivity cell. The FEC will perform and document this quality control check at least annually, especially if the meter is used for NPDES monitoring activities. A label will be placed on the field instruments to indicate when the next verification check is required. 16.2 Temperature EISOPQAM 16 -1 November 2001 I I I I I I I I I I I I I I I I I I Normally, temperature measurements may be made with any good alcohol-filled thermometer or a NIST traceable digital ti1ermometer. As a minimum, the thermometer should be capable ofreading or have a scale marked in 0.1 °C. For field operations with glass thermometers, a thermometer having a metal case to prevent breakage should be used. Calibration: Calibrate any temperature measurement device by checking annually against a National Institute of Standards and Technology (NIST) certified thermometer. Clearly indicate whatever correction must be applied to the thermometer. Note: Thermistors should be checked against a NIST traceable thermometer prior to use and should agree witilin ± 4.0 °C. Corrections must be applied for measurements up to± 4.0 °C, but the instrumentation must be repaired or replaced beyond that range. Inspection: All thermometers should be inspected for leaks, cracks, and/or function prior to use. Procedures: (Make measurements in-situ when possible) Units: I. Clean the probe end with de-ionized water and immerse into sample. 2. Swirl the thermometer in the sample for mixing and equilibration. 3. Allow the thermometer to equilibrate with the sample for at least one minute. 4. Suspend the thermometer away from the sides and bottom to observe the reading. 5. Record the reading in ti1e log book. Report temperatures readings to the nearest 0.5 °C for most applications. Note: Always clean the thermometer prior to storage and/or use. Degrees Celsius (°C) or Degrees Fahrenheit (0 F) Conversion Formulas: °F = (9/5 °C) + 32 or °C = 5/9 (°F -32) EISOPQAM 16 - 2 November 2001 I I I I I I I I I I I I g D D u I I I I 16.3 Conductivity (Specific Conductance) Conductivity is a measure of the ability of an aqueous solution to conduct an electric current. Conductivity is customarily reported in micromhos per centimeter (µmhos/cm) at 25 °C. It is important to note that if the conductivity measurements are for NPDES reporting purposes, the meter and conductivity cell should be verified by comparing against a laboratory meter with a platinum-electrode type conductivity cell. Equipment available: • Orion Model 140 conductivity meter Calibration: The meter is calibrated in accordance with the manufacturer's instructions by the FEC before it is taken into the field. A two-point calibration verification should be used to ensure the accuracy of the meter. The cell constant of the 014000 series cell is automatically set (0.0609/cm) by the meter. All field conductivity meters are verified against a National Institute of Standards and Technology (NIST) traceable thermometer, the Hanna Instruments CheckTemp 1 or equivalent, at least semi-annually. 111ese verification checks are documented in a logbook and maintained at the Federal Equipment Center (FEC). Labels are placed on the conductivity meters to indicate when the next temperature verification check is required. Conductivity is affected by temperature; therefore, temperature should be read first so that appropriate adjustments can be made in accordance with the manufacture's instructions and the method. Fresh standards should be obtained and used for each field trip. Discard standard solutions after each calibration verification. 1. Make sure the meter is warmed up as per manufacturer's directions. Verify the meter's internal temperature sensor against a NIST traceable Fisher brand stem-type digital thermometer, or equivalent, and note any differences in your logbook. If the temperature readings agree within ± 4 ° C, apply any necessary correction factor and proceed with measuring the temperature of the standard solutions within 0.5 °C. If the temperatures do not agree within± 4 ° C, the unit must be repaired or replaced. Substitute the NIST traceable thermometer for temperature readings and apply necessary corrections. Check and record the temperatures of the standards and the samples. 2. Rinse U1e probe with de-ionized water and blot dry before immersing it in the standard solution. One standard should be close to 1412 µmhos/cm (0.01 M KCL) and the other standard should be in the expected range of the samples being measured. 3. Immerse the probe in the first standard solution (0.01 M KCL) and record the results. The difference between the standard and U1e measured result is how the cell constant is determined. Document the measurement in U1e logbook to calculate the cell constant to be used in the calculations if necessary. 4. Rinse the probe, blot dry and immerse it into the second standard solution and record results. If the meter is not accurate to within± 10% of the second standard, the cell should be repaired or replaced if possible. If this is not possible, the cell constant can be adjusted by pressing the °C.TC.C key until the cursor in right LCD display indicates "TC". Adjust TC to 0.00 by using the up/down scroll keys. Press the °C.TC.C key to select the C mode. Inunerse cell into a solution of known conductivity (e.g. 445 µmhos/cm @ 25 °C). Press the up/down scroll keys until the meter indicates the known conductivity of the solution in the left LCD display. The new cell constant will now be shown in the meter C display (right LCD display). Document the readings before proceeding. EISOPQAM 16 - 3 November 2001 I I I I I I I B D I I I I I I I I I Procedures: Units: I. Collect ll1e sample, check and record its temperature. If possible, allow the sample to come to room temperature (23 to 27 °C). 2. Correct the instrument's temperature adjustment to the temperature of the sample (if required). 3. Immerse the probe in the sample keeping it away from the sides and bottom of the container. It is important that the center portion of the probe be wetted by the sample. 4. Allow meter to stabilize. Record the results in a log book. 5. Rinse probe with de-ionized water. The Orion Model 140 conductivity meter has automatic temperature compensation and will read out directly in µmhos/cm corrected to 25 °C. If another meter is used that is not temperature correcting, a correction must be applied. If the sample temperature is below 25 °C, add 2% of the reading per degree. If the temperature is above 25 °C, subtract 2% of the reading per degree. Results should be reported to the nearest ten (I 0) units for readings below 1,000 µmohs/cm @ 25 °C and to the nearest one hundred (100) units for reading above 1,000 µmohs/cm @ 25 °C. 16.4 Hydrogen Ion Concentration (pH) The pH is defined as the negative logarithm of the effective hydrogen-ion concentration. For routine work use a pH meter accurate and reproducible to 0.1 pH unit with a range of 0 to 14 and equipped with a temperature-compensation adjustment. Meter{s) available: • Orion Model 230A or 290A • Hydrolab Surveyor II • YSI 3530, 3500 Water Quality Monitoring System Calibration: Because of the wide variety of pH meters and accessories, detailed operating instructions cannot be incorporated into this method. Each analyst should become acquainted with the operation of the meter used and follow manufacturer's instructions. The following calibration guidelines are minimum requirements. The meter is calibrated in accordance with the manufacturer's instructions by the FEC before it is taken into the field. A two-point calibration verification should be used to ensure the accuracy of the meter. All field pH meters are verified against a National Institute of Standards and Technology (NIST) traceable thermometer, l11e Hanna Instruments ChcckTemp I or equivalent, at least semi-annually. These verification checks are documented in a logbook and maintained at the FEC. Labels are placed on the pH meters to indicate when the next temperature verification check is required. EISOPQAM 16 - 4 November 2001 I I I I I I I H D I I i I I I ' I I I I I I Note: I. Make sure the meter is warmed up as per manufacturer's directions. Verify the meter's internal temperature sensor against a NIST traceable Fisher brand stem-type digital U1ermometer, or equivalent, and note any differences in the logbook. If the temperature readings agree wiUtin ± 4 ° C, apply any necessary correction factor and proceed with measuring the temperature of the standard solutions witltin 0.5 °C. If the temperatures do not agree witltin ± 4 ° C, the unit must be repaired or replaced. Substitute the NIST traceable thermometer for temperature readings and apply necessary corrections. Check and record the temperatures of the standards and the samples. 2. The pH of the sample to be tested should be estimated either from ltistorical data or by using a four-color pH indicator paper or equivalent. Using Utis information, calibrate the pH meter with the two buffers that bracket the expected pH range. Select either pH 4 \lfld 7 or pH 7 and 10 buffer solutions. 3. Rinse the probe with de-ionized water, blot dry and immerse it into the first buffer (pH 7) and calibrate the meter to read the correct pH. 4. Rinse the probe with de-ionized water, blot dry and immerse it into the second buffer and calibrate the meter to read the correct pH. Record the buffer values/ temperatures used to calibrate the meter. 5. Rinse the probe with de-ionized water, blot dry and immerse it into the original buffer (pH 7) and read as a sample. If the meter reads within± 0.1 pH unit of the known value of the buffer, record the value returned by the meter. 6. Rinse the probe with de-ionized water, blot dry and immerse it into the second buffer used (pH 4 or 10) and read as a sample. If the meter reads witltin ±·0.1 pH unit of the known value of the buffer, record the value returned by the meter. Procedures: 7. Rinse the probe with de-ionized water and store it in the manufacturer's recommended storage solution. Leave the meter on until all sample measurements are perfoffiled and the results are recorded. It is recommended that the meter be checked periodically against the known buffer values if used for extended periods (> 4 hrs). 8. If the meter is turned off, it must be recalibrated. I. Collect a sample. Measure the temperature prior to measuring the pH. Note: When U1e pH meter response is slow, unstable, or non-reproducible, it may be necessary to check the conductivity. If the conductivity is lower than 20 to 30 µmhos/cm then add I ml of lM potassium chloride solution per 100 mls of sample. Recheck the pH and record. 2. Immerse the probe in the sample keeping it away from the sides and bottom of the sample container. Allow ample time for the probe to equilibrate wiU1 the sample wltile gently stirring the sample. 3. While suspending U1e probe away from the sides and bottom of the sample container, record EISOPQAM 16 -5 November 2001 I I I I I I n D I I I I I I I I I I the pH. 4. Rinse the probe wiU1 de-ionized water and store itin a de-ionized water filled containeruntil the next sample is ready. Operational check: 1. While in use, periodically check U1e pH by rinsing U1e probe with de-ionized water, blot dry and immerse it into the pH 7 buffer solution. 2. Perform a post calibration verification at the end of the day and record all measurements. Units of pH are Standard Units (SU) and should be read in one-hundredths (0.01) and recorded in tenU1s (0.1 ). Note: If the pH measurements are to be used for RCRA regulatory purposes and when the pH approaches the alkaline end (pH ~ 11.0) of the scale, the pH measurements should be made by a qualified analyst using laboratory quality equipment to control the sample at 25°C ±l°C. 16.5 Turbidity A nephelometer/turbidimeter is used in comparing the turbidity of liquids by viewing light through U1em and detennining how much light is eliminated. Meter(s) available: • Hach 21 OOP Portable Turbidimeter Calibration: 1. The turbidimeter is calibrated with Formazin Primary Standards semi-annually by the FEC and a record of the calibration is maintained on file at the FEC. Labels are placed on the turbidimeters to indicate when the next calibration is required. The turbidimeter should be verified with the Gelex secondary standards in the field before each use. The Gclex Secondary Standards are supplied with the instrument, but must be assigned values before use after U1e formazin calibration.. If the instrument readings do not agree within ± 10 % of U1e Gelex standards, the unit must be recalibrated, repaired or replaced. TI1ese verifications should be documented in the inspector's logbook. 2. Tum the meter "ON". 3. Rinse the sample cell 3 times wiU1 organic free or de-ionized water. 3. Fill the cell to the fill line with organic free or de-ionized water and then cap the cell. 4.

Periodically check the turbidity meter during the day by using the gelex secondary standards provided. 2. Preform a post calibration at the end of the day and record all measurements. Turbidity measurements are reported in nephelometric turbidity units (NTUs). It is important to note that if the turbidity measurements are for NPDES reporting purposes, all values above 40 NTU must be diluted with turbidity free water and calculated by multiplying by a dilution factor. EISOPQAM 16 - 7 November 2001 I I I I I I u u B I I ' I I I I I I 16.6 Salinity Salinity is the measure of salts of the alkali metals or of magnesium found in water. This measurement is based on the direct proportionality between the magnitude of an induced electric current and the electrical conductivity of the water in which it is induced. Salinity is the total amount of salts (in grams) in 1 Kg of sea water expressed as parts per thousand. Meters available: • Beckman Model RS5-3 Portable Salinometer • Hydrolab Surveyor II • Scout • Datasone Salinometer Calibration/Maintenance: • Follow the manufacturer's instructions. • Routinely check the Beckman meter against a resistor matched to the meter. Procedures: Units: • The Beckman has an accuracy of± 0.3 parts per thousand (ppt) salinity,± 0.05 °C temperature, and ± 0.5 millimhos/cm specific conductance. • The Hydrolab Surveyor 11, Scout, and Datasone Salinometer have an accuracy of± 0. 7 ppt at I% full scale conductance at± 0.1 °C. • These meters are suited for use in brackish to saline waters having a salinity range of0 to 40ppt. Units are reported as salinity in the nearest tenth of a ppt (0.1 ppt). 16.7 Dissolved Oxygen (DO) Meter available: • YSI Models 55, 57 or 58 membrane-covered electrode (ME) DO meter Inspection: Membrane-covered electrode systems utilize a sensing element that is protected by an oxygen- permeable membrane t11at serves as a diffusion barrier against impurities. The meters for determining tlle DO in water are dependent upon electrochemical reactions. Under steady-state conditions tlle current is directly proportional to the DO concentration. Interfacial dynamics at the ME/sample interface are a factor in probe response and a significant degree or interfacial turbulence is necessary. For precision performance, turbulence should be constant. • Prior to field use, the membrane of the DO probe should be inspected for air bubbles and/or holes. If air bubbles or holes exist, replace the membrane. • The membrane should he checked for dryness. If the membrane is dry, replace and soak it in analyte-free water prior to calibration of the meter. EISOPQAM 16 - 8 November 2001 I I I I R D I I I I I I I ' I I I I I I Calibration: • Air calibrate according to the manufacturer's instructions, eiU1er in air saturated water or in a water saturated air environment. • The ME meter can be calibrated against the Winkler me01od as a QC check if desired. Procedures: I. When making measurements, be sure that the ME stirring apparatus is working. 2. Adjust the temperature and salinity compensators (if equipped). 3. Read the dial to the nearest 0.1 mg/I and record 01e measurement To Collect a Sample: Units: I. When possible, measure the DO in-situ with a field probe; otherwise, 2. Collect the sample by completely filling a 300-ml BOD botOe, stopper and measure the DO with a laboratory type probe. Note: Special care should be exercised to avoid entrainment of atmospheric oxygen or loss of DO. The sample should be collected with a DO Dunker (APHA-type) for depths less than five feet below water surface (BWS). A Kemmerer type sampler is recommended for depths greater 0ian five fe.et BWS. 3. If an APHA-type DO Dunker is not available and a shallow depth sample is needed, a bucket may be used to collect a sample of water. A siphon tube should be coiled into the bucket such that 01e fill end is nearest the bottom. Using a 300-ml BOD bottle, allow the siphoning sample to fill and overflow the bottle for a minimum of three volumes. 4. If a Kemmerer sampler is used, 01e BOD sample bottle should be filled to overflowing by inserting the outlet tube of the sampler to the bottom of the bottle. The tube should be withdrawn slowly as the bottle is allowed to overflow tlrree times its volume. Care must be exercised to prevent turbulence or the formation of bubbles when filling the bottle. Duplicate analyses should agree within± 0.1 mg/I. Units should he reported in mg/I. Limitations: • • Dissolved inorganic salts arc a factor with the performance of DO probes. Note: Make note if inorganic salts arc present in levels tliat may represent possible interferences. Dissolved oxygen ME probes are temperature sensitive, and temperature compensation is normally provided by the manufacturer (see manufacturer's instructions).

Inspection: Note: The Hach reagents and colorimeter or spectrophotometer are accepted by the US-EPA for NPDES monitoring if used in accordance with approved procedures. The pre- printed calibration scales provided by the manufacturer are based on factors developed under ideal conditions and are only acceptable if verified. The calibration scale must be initially verified using multiple (4-5) standards and a blank. The calibration scale or curve must be verified at least daily using a blank and one high and one low standard representative of the linear working range. These standard checks must agree within ±10% of the original scale or a new curve must be prepared. Verification data should be recorded and maintained on file (See Standard Methods). Use either 1-cm or 2.5-cm cells depending upon concentration range of the sample. • Each meter should be visually inspected before and after each use. Report any problems to the FEC. • Check the battery strengU1. • Insure that the reagents are fresh before field trips. Calibration: • The calibration scales must be calibrated onsite with a minimum of three points: a blank and two known standards that bracket the expected sample concentrations. Note: If the DPD kit is used, the method must adhere to the requirements set forth in Standard Methods. Reagents/Standards: • DPD total residual chlorine powder packets. • Note: 111e packets deteriorate in the presence of moisture or high temperature. The packets should be discarded if they have caked or have turned brown. Always wear gloves when handling the DPD oxalate. Do not ingest the DPD oxalate.

Present standard procedures for sample control. Present standard procedures for chain-of-custody . • Present standard procedures for maintenance of field records and document control. 3.1 Introduction Sample identification, chain-of-custody records, receipt for sample forms, and field records (with the exception of surveying notes) should be recorded with waterproof, non-erasable ink. If errors are made in any of these documents, corrections should be made by crossing a single line through the error and entering the correct information. All corrections should be initialed and dated. If possible, all corrections should be made by the individual making the error. If information is entered onto sample tags, logbooks, or sample containers using stick-on labels, the labels should not be capable of being removed without leaving obvious indications of the attempt. Labels should never be placed over previously recorded information. Corrections to information recorded on stick- on labels should be made as stated above. Following are definitions of terms used in this section: Project Leader: The individual with overall responsibility for conducting a specific field investigation in accordance with this SOP Field Sample Custodian: Individual responsible for maintaining custody of the samples and completing the sample tags and Chain-of-Custody Record Sample Team Leader: An individual designated by the project leader to be present during and responsible for all activities related to the collection of samples by a specific sampling team. Sampler: The individual responsible for the actual collection of a sample. Transferee: Any individual who receives custody of samples subsequent to release by the field sample custodian. Laboratory Sample Custodian: Individual responsible for accepting custody of samples from the field sample custodian or a transferee. One individual may fulfill more than one of the roles described above. EISOPQAM 3 - I November 2001 I I I I I I D D I I I I I I I I I I 3.2 Sample arid Evidence Identification PERFORMANCE OBJECTIVE: • To accurately identify samples and evidence collected . 3.2.1 Sample Identification The method of sample identification used depends on the type of sample collected. In-situ field samples are those collected for specific field analysis or measurement where the data are recorded directly in bound field logbooks or on the Chain-of-Custody Record, with identifying information, while in the custody of the sampling team. Examples of such in-situ field measurements and analyses include pH, temperature, dissolved oxygen and conductivity. Samples other than those collected for in-situ analysis are identified by using a standard sample tag (Figure 3-3) which are attached to the sample container. In some cases, particularly with biological samples, the sample tag may have to be included with or wrapped around the sample. Sample tags are sequentially numbered and are accountable documents after they are completed and attached to a sample or other physical evidence. The following information shall be included on the sample tag using waterproof, non-erasable ink: • project number; • field identification or sample station number; • date and time of sample collection; • designation of the sample as a grab or composite; • a very brief description of tile sampling location; • the signature of either the sampler(s) or the designated sampling team leader and the field sample custodian (if appropriate); • whether the sample is preserved or unpreserved; • U1e general types of analyses to be performed (checked on front of tag); and • relevant comments (such as readily detectable or identifiable odor, color, or known toxic properties). Samples or other physical evidence collected during criminal investigations arc to be identified by using the "criminal sample tag." 1his tag is similar to the standard sample tag shown in Figure 3-3, except that it has a red border around the front and.a red background on the back of the tag. If a criminal sample tag is not available, the white sample tag may be used and should be marked "Criminal" in bold letters on the tag. If a sample is split with a facility, state regulatory agency, or other party representative, the recipient should be provided (if enough sample is available) with an equal weight or volume of sample (see Section 2.3.6). 3.2.2 Photograph, Digital Still Image and Video Identification EISOPQAM 3-2 November 2001 I I I • I I D m i i I I I I ' I I I i I I I I Photographs and DiQital Still Images When photographs or digital images are taken, a record of each exposure or image shall be kept in a bound field logbook. The following information shall be recorded in the logbook: • • • an accurate description of what the photograph or image shows, including the name of the facility or site and the specific project name and project number; the date and time that the photograph or image was taken; the name of the individual who took the photograph or digital image . When photographs arc.used in technical reports or placed in the official files, the film shall be developed with the negatives supplied uncut. The identifying information that was recorded in the field logbook shall be entered on the back of the prints. For criminal investigations, the negatives must be maintained with the bound field logbook in the project file and stored in a secured file cabinet. When digital images are used in technical reports or placed in the official files, the disk with the original, unaltered file of the images or a printed copy of the unaltered images shall be placed in the official files as well. If printed copies of the images are used, each image shall be identified using the information that was recorded in the field logbook. For enforcement cases, it is imperative that the individual who took the image be identified in the field logbook in the event their testimony is required. Video When a video tape is made for use as evidence in an enforcement case, the following information should be recorded in a bound field logbook: • the date and time that the video was recorded;. • a brief description of the subject of the video tape; • the person recording the video. Video records shall include a visual notation (placard) at the beginning of the of the video with the appropriate information (i.e., location, date, time). An audio record may also be included in U1c video tape with the above logistical information as well as a narrated description of the video record. A label shall be placed on U1e video tape with the appropriate identifying information (i.e., project name, project number, date, location etc.). In the event testimony regarding a video tape recording is required for an enforcement case, one individual should be responsible for recording the video for each case. The original, unaltered tape shall be placed in the official files. 3.2.3 Identification of Physical Evidence Physical evidence, other than samples, shall be identified by using a sample tag or recording the necessary information on the evidence. When samples are collected from vessels or containers which can be moved ( drums for example), the vessel or container should be marked with the field identification or sample station number for future identification, when necessary. The vessel or container may be labeled with an indelible marker (e.g., paint stick or spray paint). The vessel or container need not be marked if it already has a unique marking or serial number; however, these numbers shall be recorded in the bound field log- EISOPQAM 3-3 November 2001 I I I I I I I I B D I I I I I I I hooks. In addition, it is suggested that photographs of any physical evidence (markings, etc.) he taken and the necessary information recorded in the field logbook. · Occasionally, it is necessary to obtain recorder and/or instrument charts from facility owned analytical equipment, flow recorders, etc., during field investigations and inspections. Mark the charts and write the following information on these charts while they are still in the instrument or recorder : • • • Starting and ending ti_me(s) and date(s) for the chart . An instantaneous measurement of the media being measured by the recorder shall be taken and entered at the appropriate location on the chart along with the date and time of the measurement. A description of the location being monitored and other information required to interpret the data such as type of flow device, chart units, factors, etc. After the chart has been removed, the field investigator shall indicate on the chart who the chart (or copy of the chart) was received from and enter the date and time, as well as the investigator's initials. Documents such as technical reports, laboratory reports, etc., should be marked with the field investigator's signature, the date, the number of pages, and from whom they were received. Confidential documents should not be accepted, except in special circumstances such as process audits, hazardous waste site investigations, etc. 3.3 Chain-of-Custody Procedures PERFORMANCE OBJECTIVE: • To maintain and document the possession of samples or other evidence from the time of collection until they or the data derived from the samples are introduced as evidence. 3.3.1 Introduction Chain-of-<:ustody procedures are comprised of the following elements: I) maintaining custody of samples or otl1er evidence, and 2) documentation of the chain-of-custody for evidence. To document chain- of-custody, an accurate record must be maintained to trace the possession of each sample, or other evidence, from the moment of collection to its introduction into evidence. 3.3.2 Sample Custody A sample or other physical evidence is in custody if: • it is in the actual possession of an investigator; • it is in the view of an investigator, after being in tl1eir physical possession; • it was in U1e physical possession of an investigator and then they secured it to preventtampering; and/or • it is placed in a designated secure area. 3.3.3 Documentation of Chain-of-Custody EISOPQAM 3-4 November 2001 I I I I I I :1 I ' u I I I I I I I I I I I Sample Tag A sample tag (Figure 3-3) should be completed for each sample using waterproof, non-erasable ink as specified in Section 3.2. Sample Seals Samples should be sealed as soon as possible following collection using 01e EPA custody seal shown in Figure 3-5. The sample custodian should write Ole date and Oleir initials on Ole seal. Except for criminal investigations, Ole use of custody seals maybe waived if field investigators keep Ole samples in Oleircustody as defined in Section 3.3.2 from Ole time of collection until Ole samples are delivered to the laboratory analyzing Ole samples. Custody seals will always be used for criminal investigations. Chain-of-Custody Record TI1e field Chain-Of-Custody Record (Figure 3-1) is used to record Ole custody of all samples or oilier physical evidence collected and maintained by investigators. All physical evidence or sample sets shall be accompanied by a Chain-Of-Custody Record. This Chain-Of-Custody Record documents transfer of custody of samples from Ole sample custodian to another person, to the laboratory, or other organizational elements. To simplify the Chain-of-Custody Record and eliminate potential litigation problems, as few people as possible should have custody of the samples or physical evidence during the investigation. This form shall not be used to document Ole collection of split samples where there is a legal requirement to provide a receipt for samples (see Section 3.4). The Chain-Of-Custody Record also serves as a sample logging mechanism for the laboratory sample custodian. A separate Chain-of-Custody Record should be used for each final destination or laboratory used during the investigation. · All information must be supplied in Ole indicated spaces (Figure 3-1) to complete the field Chain- Of-Custody Record. TI1e reverse side of the Chain-of-Custody Record (Figure 3-2) describes Ole requirements for station ID, sample ID and media codes • All samplers and sampling team leaders (if applicable) must sign in the designated signature block. • • • • • One sample should be entered on each line and not be split among multiple lines . If multiple sampling teams are collecting samples, the sampling team leader's name should be indicated in the "Tag Number" column (or adjacent to this column) for the appropriate sample(s). If the individual serving as 01e field sample custodian is different from Ole individual serving as Ole project leader, the field sample custodian's name and the title of the sample custodian (e.g., Jane Doe, Sample Custodian) should be recorded in t11e "Remarks/Air bill" block at Ole top of the Chain-of-Custody Record. The "Remarks/ Air bill" block may also be used to record Air bill numbers or registered or certified mail serial numbers. The total number of sample containers for each sample must be listed in the "Total Containers" column. The number of individual containers for each analysis must also be listed in the respective column. Required analyses should be circled or entered in the appropriate location as indicated on the Chain-of-Custody Record. The tag numbers for each sample and any needed remarks should be in the "Tag Numbers" column. EISOPQAM 3-5 November 2001 I I I I I I D I I I I 1• I I I I I I • • 1l1e sample custodian and subsequent transferee(s) should document the transfer of the samples listed on the Chain-of-Custody Record. 1l1e person who originally relinquishes custody should be U1e sample custodian. Both U1e person relinquishing the samples and U1e person receiving them must sign the form. The date and time U1at U1is occurs should be documented in the proper space on the Chain-of-Custody Record. Usually, the last person receiving U1e samples or evidence should be the laboratory sample custodian or their designcc(s). The Chain-of-Custody Record is a serialized document. Once the Record is completed, it becomes an accountable document and must be maintained in the project file. The suitability of any other form for chain-of-custody should be evaluated based upon its inclusion of all of the above information in a legible format. · If chain-of-custody is required for documents received during investigations, the documents should be placed in large envelopes, and the contents should be noted on the envelope. The envelope shall be sealed and an EPA custody seal placed on the envelope such that it cannot be opened without breaking the seal. A Chain-Of-Custody Record shall be maintained for the envelope. Any time the EPA seal is broken, that fact shall be noted on the Chain-Of-Custody Record and a new seal affixed. The information on tile seal should include tile sample custodian's initials and the date. Physical evidence such as video tapes or other small items shall be placed in Zip-Loe® type bags or envelopes and an EPA custody seal should be affixed so that they cannot be opened without breaking the seal. A Chain-Of-Custody Record shall be maintained for tilese items. Any time the EPA seal is broken, that fact shall be noted on the Chain-of-Custody Record and a new seal affixed. The information on U1e seal should include the sample field custodian's initials and U1e date. EPA custody seals can be used to maintain custody of other items when necessary by using similar procedures as U1ose previously outlined in this section. Samples should not be accepted from other sources unless U1e sample collection procedures used are known to be acceptable, can be documented, and the sample chain-of-custody can be established. If such samples are accepted, a standard sample tag containing all relevant information and the Chain-Of-Custody Record shall be completed for each set of samples. 3.3.4 Transfer of Custody with Shipment • Samples shall be properly packaged for shipment in accordance with the procedures outlined in Appendix D. • All samples shall be accompanied by the Chain-Of-Custody Record. The original and one copy of the Record will be placed in a plastic bag inside the secured shipping container if samples are shipped. When shipping samples via common carrier, the "Relinquished By" box should be filled in; however, the "Received By" box should be left blank. The laboratory sample custodian is responsible for receiving custody of the samples and will fill in the "Received By" section of the Chain-of-Custody Record. One copy of the Record will be retained by the project leader. The original Chain-of-Custody Record will be transmitted to the project leader after the samples are accepted by the laboratory. This copy will become a part of the project file. • If sent by mail, U1e package shall be registered with return receipt requested. If sent by common carrier, an Air Bill should be used. Receipts from post offices and Air Bills shall be retained as part of the documentation of the chain-of-custody. The Air Bill numberor registered mail serial number shall be recorded in the remarks section of the Chain-Of-Custody Record. EISOPQAM 3-6 November 2001 I I I I I I 0 I I I I -I I I I I I 3.4 Receipt for Samples Form (CERCLA/RCRAfl'SCA) PERFORMANCE OBJECTIVE: • To assure that staff comply wiU1 environmental laws which require providing a Receipt for Samples Form. 3.4.1 Introduction Section 3007 of the Resource Conservation and Recovery Act (RCRA) of 1976 and Section 104 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund) of 1980 require that a "receipt" for all facility samples collected during inspections and investigations be given to the owner/operator of each facility before the field investigator departs the premises. The Toxic Substances Control Act (TSCA) contains similar provisions. The laws do not require that homeowners or other off-site property owners be given this form. 3.4.2 Receipt for Samples Form The Receipt for Samples form (Figure 3-4) is to be used to satisfy the receipt for samples provisions of RCRA, CERCLA, and TSCA. The form also documents that split samples were offered and either "Received" or "Declined" by the owner/operator of the facility or site being investigated. All information must be supplied in the indicated spaces to complete the Receipt for Samples form. • · The sampler(s) must sign the form in the indicated location. If multiple sample teams are collecting samples, the sample team leader's name should be indicated in the "EPA Sample Tag No./Remarks" column. • Each sample collected from the facility or site must be documented in the sample record portion of the form. The sample station number, date and time of sample collection, composite or grab sample designation, whether or not split samples were collected (yes or no should be entered under the split sample column), the tag numbers of samples collected which will be removed from the site, a brief description of each sampling location, and the total number of sample containers for each sample must be entered. • The bottom of the form is used to document the site operator's acceptance or rejection of split samples. TI1e project leader must sign and complete the information in the "Split Samples Transferred By" section ( date and time must be entered). lf split samples were not collected, the project leader should initial and place a single line through "Split Samples Transferred By" in this section. The operator of the site must indicate whether split samples were received or declined and sign the form. The operator must give their title, telephone number, and t11e date and time they signed tl1e form. lf the operator refuses to sign the form, the sampler(s) should note tl1is fact in the operator's signature block and initial Ulis entry. TI1e Receipt for Samples form is serialized and becomes an accountable document after it is completed. A copy of the fonn is to be given to U1e facility or site owner/operator. The original form must be maintained in the project files. 3.5 Field Records EISOPQAM 3-7 November 2001 I I I I I I I D I I I I I I I I ' I I I PERFORMANCE OBJECTIVE: • To accurately and completely document all field activities . Each project should have a dedicated logbook. l11e project leader's name, the sample team leader's name (if appropriate), the project name and location, and the project number should be entered on the inside of the front cover of the logbook. It is recommended that each page in the logbook be numbered and dated. The entries should be legible and contain accurate and inclusive documentation of an individual's project activities. At the end of all entries for each day, or at the end of a particular event, if appropriate, the investigator should draw a diagonal line and initial indicating the conclusion of the entry. Since field records are the basis for later written reports, language should be objective, factual, and free of personal feelings or other terminology which might prove inappropriate. Once completed, these field logbooks become accountable documents and must .be maintained as part of the official project files. All aspects of sample collection and handling, as well as visual observations, shall be documented in the field logbooks. The following is a list of information that should be included in the logbook: 3.6 • sample collection equipment (where appropriate); • field analytical equipment, and equipment utilized to make physical measurements shall be identified; • · calculations, results, and calibration data for field sampling, field analytical, and field physical measurement equipment; • property numbers of any sampling equipment used, if available; • sampling station identification; • time of sample collection; • description of the sample location; • description of the sample; • who collected the sample; • how the sample was collected; • diagrams of processes; • maps/sketches of sampling locations; and • weather conditions that may affect the sample (e.g., rain, extreme heat or cold, wind, etc.) Document Control EISOPQAM 3-8 November 2001 I I I I I I D R I I I I I I I I I I PERFORMANCE OBJECTIVE: • To assure that project files are maintained in accordance with Divisional guidelines . Document control refers to the maintenance of inspection and investigation project files. All information below shall be kept in project files. Investigators may keep copies of reports in their personal files, however, all official and original documents relating to inspections and investigations shall be placed in the official project files. The following documents shall be placed in the project file, if applicable: • request memo from the program office; • copy of the study plan; • original Chain-Of-Custody Records and bound field logbooks; • copy of the Receipt for Sample forms; • records obtained during the investigation; • complete copy of the analytical ·data and memorandums transmitting analytical data; • official correspondence received by or issued by the Branch relating to the investigation including records of telephone calls; • photographs and negatives associated with the project; • one copy of U1e final report and transmittal memorandum(s); and • relevant documents related to the original investigation/inspection or follow-up activities related to the investigation/inspection. Inappropriate personal observations and irrelevant information should not be ·placed in the official project files. At the conclusion of the project, the project leader shall review the file to ensure that it is complete. EISOPQAM 3-9 November 2001 I I I I I I I H I I I I I I I I I I I 3.7 Disposal of Samples or Other Physical Evidence PERFORMANCE OBJECTIVE: • To ensure Uiat proper disposal procedures are used for samples or other evidence . Disposal of samples or other physical evidence obtained during investigations is conducted on a case- by-case basis. Before samples which have been analyzed are disposed of, the ASB sample custodian shall contact the project leader via E:mail, indicating that the samples will be disposed of by a certain date unless the project leader dictates otherwise. If the sample custodian does not receive a message from the project leader within the time specified in the E:mail, the samples will be disposed of. Personnel should check with the EPA Program Office requesting the inspection or investigation before granting pcnnission to dispose of samples or other physical evidence. The following general guidance is offered for the disposal of samples or other physical evidence: 3.8 • No samples, physical evidence, or any other document associated with a criminal investigation shall be disposed of without written pcnnission from EP A's Criminal Investigations Division. • Samples associated with routine inspections may be disposed of following approval from U1e project leader. Sample tags will be discarded along with the samples. Field Operations Records Management System (FORMS) PERFORMANCE OBJECTIVE: • To introduce the procedure for streamlining sample documentation FORMS is a computer program designed to streamline the documentation required by SESD and/or the Contract Laboratory Program (CLP) for sample identification and chain-of-custody. Once the appropriate information is entered into the computer, FORMS will generate stick-on labels for the sample tags and sample containers (CLP), and will generate sample receipt forms and chain-of-custody records for the appropriate laboratory. The advantages to this system include faster processing of samples and increased accuracy. Accuracy is increased because U1e information is entered only once, and consequently, consistent for the tags, bottle labels, sample receipt forms and chain-of-custody records. Operating instructions are available for use with the FORMS program.
