Groundwater Monitoring Plan: Old Salisbury Road C&D Landfill ��� Introduction 1 Introduction This Groundwater Monitoring Plan for the Old Salisbury Road Construction and Demolition Debris (C&D) Landfill (OSR), is intended to update and replace the plan approved in April of 2015 as part of the previous permit renewal process. 1.1 Facility Background The OSR landfill is permitted for 56 acres and is situated within a 140-acre tract north of Friedberg Church Road and west of Old Salisbury Road in Forsyth County, North Carolina. The site is accessed via Old Salisbury Road (State Road 3011). The Davidson County line borders the site to the south. The location of the OSR landfill is illustrated on Figure 1. 1.2 Regulatory Authority The site is operated under North Carolina Department of Environmental Quality (NCDEQ) facility permit number 34-12. The facility was first issued a permit to operate on July 3, 1996 and opened in August of the same year. The monitoring requirements for this site are addressed by North Carolina Solid Waste Management Rule 15A NCAC 13B .0544. This plan addresses the monitoring requirements for groundwater and surface water. Landfill gas is addressed in a separate monitoring plan. 1.3 Geologic Characteristics This section paraphrases the descriptions provided in the July 2003 Ground Water Monitoring Plan and the 2003 Design Hydrogeologic Investigation Report. 1.3.1 Regional Geologic and Hydrogeologic Frame Work According to the 1985 Geologic Map of North Carolina, OSR is located in the Charlotte belt of the Piedmont Physiographic Province. This province contains metamorphic and igneous plutonic rocks, which in some areas have been extensively weathered and eroded forming an undulating and well -dissected topography. The area is underlain by granite rock, which is commonly megacrystic to equigranular in texture. The bedrock is typically fractured and is overlain by highly weathered bedrock called saprolite. The saprolite varies in thickness from a few feet near bedrock outcrops to over 100 feet. The saprolitic material retains some of the original (relict) structural features of the parent rock. The nearer surface residual soils are formed by the in -place physical and chemical weathering of the saprolite and usually do not retain the relict structural features. Subsurface conditions generally consist of a veneer of topsoil underlain by residual soils, saprolite, partially weathered rock, and fractured rock. There is generally a gradual transition from one material type to the next with varying thickness of each. In the Piedmont Physiographic Province, groundwater is present within the openings created by fractures and joints within the bedrock and within the pore spaces of the overlying-saprolite. The saprolite/bedrock aquifers are primarily recharged by precipitation in the inter -stream areas, which infiltrates through the unsaturated zone to the water table. The depth to ground water is Winston-Salem/Forsyth County Utilities I Groundwater Monitoring Plan: Old Salisbury Road C&D Landfill ��� Introduction generally deeper beneath uplands than beneath valleys. The water table is commonly close to the top of bedrock and is more often than not, located within the saprolite. Groundwater moves laterally and downward through the saprolite and bedrock toward streams, springs, and surface water bodies. The water table surface is generally a subdued reflection of the surface topography. 1.3.2 Site Specific Topography and Drainage Surface drainage at the subject site is primarily controlled by a north -northwesterly trending ridge within the property. Construction of the landfill generally mimics and replaced the natural ridge that existed prior to the landfill. This ridge directs runoff northeast, west and southwest into tributaries of South Fork Muddy Creek. The majority of surface runoff within this site is directed to South Fork Muddy Creek on the north. A small area in the extreme southeasterly section of the site appears to drain south into Miller Creek. Both the South Fork Muddy Creek and Miller Creek flow to the west where they converge with Muddy Creek. Muddy Creek flows to the south and converges with the Yadkin River. 1.3.3 Site Specific Hydrogeology As documented in the Design Hydrogeological Investigation Report submitted by HDR on December 2, 2003, the uppermost unconfined aquifer underlying the facility is comprised of three units. The stratigraphic downward progression of the three units is saprolite transitioning into partially weather bedrock, then competent bedrock. Ground water flow through the saprolite and partially weathered bedrock is through the soil matrix, while groundwater flow through the bedrock is primarily fracture flow. The average effective porosity of the saprolite stratum is 17, while the saprolite transition zone has an effective porosity of 25. The effective porosity of the bedrock is significantly less at 2. The calculated hydraulic conductivity (K) for the saprolite is 0.259 feet per day (ft/day) (9.1 x 10-1 cm/sec). The calculated average hydraulic conductivity for the transition zone is 0.466 ft/day (1.65 x 10-4 cm/sec). The calculated hydraulic conductivity of the bedrock aquifer was slower than either the saprolite or transition zone units with a K value of 0.043 ft/day (1.5 x 10-1 cm/sec). Detailed calculations of the hydraulic conductivity, flow rates, and porosity were provided in the 2003 Design Hydrogeological Investigation Report. Based on historical field observations (i.e., soil boring records) and laboratory test results from the 2003 Design Hydrogeological Investigation Report, the uppermost unconfined aquifer beneath the facility predominantly exists within the unconsolidated saprolitic soil and transition zone units that have been classified as micaceous silty sands and sandy silts produced by the in -situ weathering of the granodiorite parent rock. Groundwater flow within the uppermost aquifer is predominantly porous flow through the unconsolidated units. There is no evidence of discrete flow patterns within the saprolite and transition zones of the uppermost aquifer resulting from relict quartz veins, dikes, healed fractures, or strong preferential alignment of minerals (i.e., foliation). In general, the flow of groundwater occurs for the facility is from higher elevations onsite to lower elevations onsite under unconfined (water table) conditions regardless of the unit in which it resides. As such, the static water table generally mimics the topography. 7 8 PROJECTMANAGER M. PLUMMER, P.E. P. BROWNSON, P.E. E. TUCKER, E.I.

Winston-Salem/Forsyth County Utilities I Groundwater Monitoring Plan: Old Salisbury Road C&D Landfill ��� Monitoring Network 1.4 Monitoring History A groundwater monitoring plan was originally prepared by S&ME and submitted by HDR with the Site Plan Application in 1995. HDR has subsequently revised this plan multiple times by letter: August 1999, October 1999, October 2002, April 2003, July 2003, and April 2015. The plan with the amending letters was last approved by NCDEQ in the April 2015 operating permit amendment. OSR is in assessment monitoring due to exceedances of groundwater quality standards, as specified in 15 NCAC 02L .0202 (2L Standards), for benzene and tetrachloroethene (PCE) detected in well MW-2R during 2011. On December 9, 2011, an assessment monitoring plan for MW-2R was submitted in accordance with 15A NCAC 13B. This plan was approved with two exceptions on January 17, 2012. The first exception required the location of MW-15 to be in the same flow path as MW-2R; the second required all wells to be sampled for 40 CFR Part 258 — "Appendix II List of Hazardous Inorganic and Organic Constituents" (Appendix II) constituents. In February 2014, Winston-Salem/Forsyth County Utilities requested, and NCDEQ approved, the following modifications to the facility's assessment monitoring plan. • Groundwater monitoring wells MW-1 R, MW-2R, MW-4R and MW-15 will be sampled semi-annually for Appendix I and the previously detected Appendix II constituents • All 14 groundwater monitoring wells (including MW-1 R, MW-2R, MW-4R and MW-15) will be sampled during every other fall event (odd years) for the entire Appendix II constituent list • Additional Appendix II constituents detected during these events will be added to the sampling program for subsequent semiannual events. In January 2016, HDR recommended changes to the semi-annual sampling schedule. NCDEQ approved sampling for additional detected parameters. The request to remove selected parameters from the sampling schedule was denied. On May 29, 2018, NCDEQ added 1,4- Dioxane (p-Dioxane) to the sampling plan for all wells on a semi-annual basis with a 2L Standard of 3 pg/L. 2 Monitoring Network The 18 ground and surface water monitoring locations are depicted on Figure 1. Groundwater monitoring well MW-1 R is located hydraulically upgradient of the landfill and is the background well for the site. MW-6R was abandoned. Upstream surface water (SW-1) and downstream surface water (SW-2) samples are obtained from the stream that flows east of the landfill unit. Surface water samples (SW-3 and SW-4) are intermediate samples obtained from the drainage channel in the vicinity of MW-2R. SW-3 is located south of the entrance road near MW-2R; SW- 4 is located on the north side of the entrance road, downstream of SW-3.

All groundwater wells will be labeled "MW-##" where the ## is the next available number. A suffix of "R#" will be added for replacement wells, where # is the sequence of replacement. The use of R and R1 will be considered synonymous. 2.1.2 New and Replacement Wells New and replacement monitoring wells will be added to the system as needed and will be installed per NCDEQ requirements and Rule 15A NCAC 2C. Well labels shall include all pertinent construction data including name, date and depth. New wells will be sampled on the same schedule as existing wells. A well will be considered a replacement well if the original well is or will be abandoned and the well will be located in the same vicinity as the well it is replacing. Formerly, the location of the replacement well was not a criterion for labeling the well as a replacement and wells that were not in the same vicinity have been labeled as replacement wells. Whenever possible, replacement wells will be installed before abandonment of the well to be replaced, so that Winston-Salem/Forsyth County Utilities I Groundwater Monitoring Plan: Old Salisbury Road C&D Landfill Waste Acceptability J samples and measurements may be obtained for comparison purposes. Otherwise a well will be considered new. 2.1.3 Abandonment of Wells All damaged or replaced wells shall be abandoned in accordance with NCDEQ requirements for well abandonment and Rule 15A NCAC 02C .0113. 2.2 Surface Water The surface water system currently consists of one upstream point (SW-1) and three downstream points (SW-2, SW-3 and SW-4). Upstream surface water and downstream surface water samples are obtained from the adjacent stream to the east. Surface water samples (SW-3 and SW-4) were obtained from the drainage channel in the vicinity of MW-2R. SW-3 is located south of the entrance road near MW-2R; SW-4 is located on the north side of the entrance road, downstream of SW-3. 3 Waste Acceptability Waste acceptability is addressed in the Permit Application's Operations Plan (Appendix C). Please refer to Sections 2 Standard Operating Procedures and 3 Waste Screening Procedures of the Operations Plan for further information. 4 Sampling Schedule Data will be collected from the 14 on -site groundwater wells and four surface water sampling locations. Table 2 provides a list of the sample locations and the sample frequency for the associated analytical parameters. The sampling schedule is based on the solid waste list of regulated parameters. The monitoring wells and surface water sampling locations listed in Table 1 will be sampled semi-annually. 5 Sampling Procedures The NCDEQ Guidelines for Groundwater, Soil, and Surface Water Sampling will be strictly followed during field sampling events. These guidelines are found in Appendix 1. i Static Groundwater Level and Total Depth Measurements The depth from the top of the polyvinyl chloride (PVC) casing to groundwater is measured to the nearest 0.01 foot prior to purging each well. This depth to water, when subtracted from the reference datum, provides a groundwater surface elevation. Record a complete set of water -level measurements within a 24-hour period for use in generating a potentiometric surface map. Water level measurements should also be recorded immediately prior to purging, along with a measurement of the total well depth. This data is required to determine the current hydraulic surface, to calculate the volume of water to be purged, and to check well integrity. All measurements are to be made in reference to the surveyed reference notch made on the top of the PVC well casing (TOC), and are recorded in the field log book to the nearest 1/100th of a foot. In order to avoid any possibility of well Winston-Salem/Forsyth County Utilities I Groundwater Monitoring Plan: Old Salisbury Road C&D Landfill ��� Sampling Procedures cross -contamination, the water level indicator probe will be rinsed with a laboratory -grade, phosphate -free detergent, rinsed with tap water, and then finally rinsed with deionized water after each well is measured. Perform the measurement to static groundwater will be performed using an electronic water level indicator. Electronic water level indicators generally consist of a probe attached to a spool of dual conductor wire and an indicator. When the probe is lowered into the well and comes into contact with the water, it completes the circuit and registers the contact and will light and/or sound. Total well depth should be determined for each sampling event by lowering a water level indicator probe until the weighted end is felt to be on the bottom. The total depth can then be read off the indicator cable. 5.2 Well Purging Purging and sample collections activities will begin at the background well(s) and generally progress from the upgradient areas to the downgradient areas and from wells that are the least impacted to those that are the most impacted. Purge each well will be purged to remove any stagnant water that may not be representative of actual groundwater quality prior to sampling. Purging three well volumes is generally adequate to reach a stabilized condition as described below. A well volume can be calculated by the following formula. Z V = 7.480527rh (2) Where: V= volume of water (gallons) 7.48052 = the number of gallons in 1 cubic foot 7r = 3.14159 h = height of water column (feet) D= inside diameter of pipe (feet) Wells that are purged dry shall be allowed to recover sufficiently to allow complete sampling of the required parameters, using the protocol outlined below. The stability of temperature, specific conductance, and pH will be checked immediately after well recovery against the previous indicator parameter measurements. No smoking, use of insect repellents, or the running of motor vehicles should occur in the immediate vicinity during purging or sampling. Decontaminate all purging/sampling equipment prior to placement into each well and handle in a manner to prevent interwell contamination. Equipment shall not be placed in contact with unclean surfaces. Do not place sample bottles and field instrumentation directly on the ground surface. Place plastic sheeting on the ground around the well casing to reduce the possibility of contamination. Samplers shall wear a clean pair of new, disposable gloves each time a different well is sampled, and gloves will be donned immediately prior to purging and shall be changed prior to sampling, if necessary. Winston-Salem/Forsyth County Utilities I Groundwater Monitoring Plan: Old Salisbury Road C&D Landfill ��� Sampling Procedures Purge water from wells with contaminant levels greater than 10 times the maximum contaminant level (MCL), based on the previous sampling event, will be containerized for disposal at a wastewater treatment plant (WWTP). Purge water from other wells shall be disposed of upgradient of the wells being sampled or to a WWTP. 5.3 Field Analysis Perform the field analyses by using field test meters that are calibrated prior to beginning well purging, following the calibration procedures specified for each instrument. Carry out calibration for the pH/temp meter using standard buffer solutions (pH 7 and pH 4) and a laboratory thermometer. Calibrate the conductivity meter to two standards. The standards shall bracket the average conductivity expected for the landfill, once the site's average conductivity has been determined. Measure Redox reduction —oxidation reaction (redox) and turbidity at each well. Field analysis will be performed throughout the well purging process to determine temperature (°C), pH, and specific conductivity (pmhos/cm) as indicators of groundwater quality stabilization. Water stabilization is achieved when specific conductance and temperature variance is within ±10 percent on three successive measurements and pH variance is within ±0.2 SU over three successive measurements. Turbidity should be less than 5 NTU or within ±10 percent on three successive measurements. Redox should be ±10 percent on three successive measurements and ORP oxidation-reduction potential should be ± 10 millivolts on three successive measurements. Sample field data sheets are provided in Groundwater Monitoring Plan Appendix D43. 5.4 Sample Withdrawal Use a variable speed micro -purge pump to evacuate groundwater from each well until stabilization of measured field parameters (pH, conductivity, redox, temperature, turbidity, and dissolved oxygen) has occurred. Following completion of purging activities, sample the wells using the same pump and record field parameters (pH, specific conductance, redox, turbidity, dissolved oxygen, and temperature) on field sampling logs. Copies of these logs are provided in Appendix D2. Pumping rates should not exceed 500 mL/minute. Sample collection will be performed in a manner to ensure that agitation and aeration of the groundwater will be minimized. Fill the containers in the following sequence of decreasing volatility: volatile organics, metals, chloride, nitrate, pH, and specific conductivity. Place the samples directly into the appropriately prepared container, as supplied by the laboratory. Collect sufficient sample volume to perform all required analyses and to provide for quality control samples. Do not overfill sample bottles containing preservatives. Consult the laboratory scheduled to perform the analysis prior to the sampling event to confirm volume and analysis requirements. Fill all preserved samples to nearly full, only so as not to flush the preservative from the bottle. Gently fill volatile organic compound (VOC) vials gently to near the top, and then fill the remainder of the vial by placing a small amount of the groundwater into the vial cap and 10 Winston-Salem/Forsyth County Utilities I Groundwater Monitoring Plan: Old Salisbury Road C&D Landfill ��� Sampling Procedures transferring this water to the sample vial until a convex meniscus is formed. Once the cap is placed onto the vial, the sample will be inverted and lightly tapped by hand to verify that air bubbles are not present. Immediately place the samples on ice for transport to the laboratory. 5.5 Equipment Decontamination Decontaminate the non -dedicated down hole equipment prior to use or reuse. Decontaminate water level meters and other auxiliary equipment should be decontaminated using a laboratory - grade, phosphate -free detergent, rinsed with tap water, and a final rinse with deionized water. Decontamination solutions are prepared and transported to the field for cleaning the sampling equipment. The decontamination procedure for sampling equipment includes the following steps. Clean equipment will be cleaned with dilute laboratory -grade phosphate -free detergent and tap water using a brush to remove particulate matter and surface films. 1. Rinse with tap water. 2. Rinse with a 10 percent nitric acid solution. 3. Rinse thoroughly with deionized water. 4. Rinse twice with isopropanol. 5. Rinse thoroughly with organic -free water and air dry. 6. If organic -free water is not available, allow equipment to air dry, do not rinse again with deionized or distilled water. 7. Wrap equipment with aluminum foil (shiny side out), if appropriate, to prevent contamination during storage or transportation. 5.6 Sample Preservation and Handling This section addresses the preservation methods and handling of samples. 5.7 Sample Containers Use sample containers supplied by the contracted laboratory based on the analyses required. Take care to prevent contamination of the containers in the field. 5.8 Sample Preservation Field preservation of samples is generally accomplished by pH control, the addition of chemicals, temperature control, and protection from light. Sample containers are received from the laboratory pre -labeled with the analysis to be performed and with preservatives added as necessary. Once properly capped, the container is inverted once to mix the preservative and sample. The containers are then securely packed into an insulated cooler with ice packs. Upon completion of the sampling event, the containers are transported to the laboratory for analysis in the most efficient manner. Overnight delivery services are typically employed to transport samples to the laboratory. The laboratory shall be certified by the state of North Carolina.

Items included in the chain of custody program are: sample labels, sample seals, field log book, and chain of custody record. 5.9.1 Sample Labels Each sample container is affixed with a durable label which will be filled out using a waterproof pen or marker. Information to be shown on the label includes, but is not limited to, the following. • Sample number • Date and time of collection • Location • Name of collector • Parameter to be analyzed • Type of preservative 5.9.2 Sample Seal 12 Winston-Salem/Forsyth County Utilities I Groundwater Monitoring Plan: Old Salisbury Road C&D Landfill ��� Sampling Procedures To ensure that samples have not been disturbed during shipment, a seal will be placed on individual containers or the entire package. 5.9.3 Field Log Book All observations and field activities will be recorded in a project -dedicated log book or on field sheets, which are placed into the project files. Field personnel, date, time, weather, results of in field analysis, and other pertinent data shall be recorded. 5.9.4 Chain of Custody Record Each sample will be documented on a chain of custody record; a sample form is provided in Appendix D43. The form is to be completed in black or blue (reproducible) ink. The following information shall be recorded. • Project number. • Project name. • All samplers' signatures in the designated block. • The sampling station number, date, and time of sample collection, grab or composite sample designation, and a brief description of the type of sample and the sampling location are included on each line (no more than one sample is included on each line of the sample record). • The total number of sample containers is given in the indicated space for each sampling location medium. The total number of individual containers is also given for each type of analysis under the indicated medium or miscellaneous columns. The type of container and required analyses is circled as indicated on the record. • The tag numbers for each sample and any needed remarks are supplied in the indicated column. • The remarks column at the bottom of the form is used to record airbill numbers or registered or certified mail serial numbers or other pertinent information as needed. • The field investigator and subsequent transferee(s) documents the transfer of the samples listed on the record in the space provided at the bottom of the record. One of the samplers documented under the sampler(s) section of the record is the person that originally relinquished the samples. Usually, the last person receiving the samples or evidence is a laboratory sample custodian or other evidence clerk. The chain of custody record is a serialized document. Once the record is completed, it is maintained in the project file. A completed copy of the chain of custody record is submitted to NC DENR NCDEQ along with the analytical reports during each routine reporting period. 5.9.5 Field Quality Assurance/Quality Control Sample Blanks To demonstrate the quality of the laboratory data, quality control (QC) samples are collected. DUPLICATE A duplicate sample shall be obtained from a different well for each event. The associated well ID will be noted on the field logs. The sample will only be identified on the chain of custody record and jar labels as "Duplicate". 13 Winston-Salem/Forsyth County Utilities I Groundwater Monitoring Plan: Old Salisbury Road C&D Landfill ��� Data Evaluation TRIP BLANK At least one trip blank will be included for each VOC sampling event. The trip blank is prepared by the contracted laboratory by filling one container with deionized water. This container is then transported to the sampling site and handled as if it were a collected sample. EQUIPMENT BLANK At least one equipment (rinsate) blank shall be collected for each sampling event that requires field decontamination. The blank shall be collected from the equipment after use on a contaminated well. The equipment blank is prepared by filling the decontaminated sampling device with deionized water and then transferring it to an appropriate sample container. This container is then handled in the same manner as other samples. Equipment decontaminated in both the field and the office will be utilized as candidates for equipment blanks. FIELD BLANK A field blank will be collected in the event that weather or environmental conditions are unstable in the vicinity of the well while it is being sampled (i.e., heavy winds, rain, dust, and heavy equipment operation). 5.9.6 Laboratory Quality Assurance/Quality Control The contracted laboratory is given the flexibility to use any QA/QC program appropriate for the specified analysis. The laboratory shall provide verification of this program's use with the results of the sample analyses. A North Carolina certified groundwater laboratory shall perform the required testing. 5.9.7 Visual Inspection A visual inspection of the wells will be conducted in conjunction with the monitoring events.

An excerpt of the bill is provided below and the entire bill can be viewed at the below link. https://www.ncleg.net/Sessions/2017/Bills/House/PDF/H573v5.pdf "SECTION 5.(c) Implementation. —Notwithstanding sub -subdivision (b)(1)(D) of the Monitoring Plans and Requirements for C&DLF Facilities Rule, the Commission shall not require semiannual monitoring frequency for required groundwater sampling but shall only require such sampling on an annual basis " For the purpose of clarification, the Solid Waste Section (SWS) presents the following assertions. • The above applies to active and closed "stand alone" CDLF facilities and CDLF units at Municipal Solid Waste Facilities where monitoring can be done separately; and excludes CDLF over MSWLF facilities. • Annual sampling frequency is only allowed for those CDLF facilities in detection monitoring. The sampling frequency at CDLF facilities conducting assessment or corrective action activities shall be on at least a semi-annual basis or according to the CDLF facility's approved Assessment or Corrective Action Work Plan. CDLF facilities with State of North Carolina I Environmental Quality I Waste Management 217 West ]ones Street 1 I646 Mail ServiCe Center I Raleigh, North Carolina 27699-1646 9l9 707 8200 documented groundwater protection standard exceedances that have not initiated assessment or corrective action should also conduct semi-annual groundwater monitoring. • Annual basis shall be perceived as a calendar year meaning January 1st to December 31 st CDLF owners and operators should communicate with their respective assigned SWS hydrogeologist to determine the appropriate season for sampling (i.e. spring or fall). • Due to possible changes in prescribed site -specific sampling seasons and/or the potential for assessment activities, the SWS recommends CDLF owners and operators to continue to budget for semiannual groundwater sampling each fiscal year. • Water Quality Monitoring Plans (WQMP) at active CDLF facilities do not need to be amended at this time. Appropriate amendments to the WQMP can be completed during the next permit modification or permit renewal process at each active CDLF facility. For closed CDLF facilities owners and operators should communicate with their respective assigned SWS hydrogeologist to determine the appropriate WQMP modifications, if warranted.

It is primarily used as a stabilizer for chlorinated solvents, however also used in many products including paint strippers, dyes, greases, varnishes and waxes. Additionally, it is found in a variety of consumer products such as detergents, shampoos, deodorants, and cosmetics. The current 15A NCAC 02L .0202 Standard for 1,4- Dioxane is 3.0 µg/1. Due to the potential health hazards associated with 1,4-Dioxane, the Section has determined that all landfills should begin analyzing groundwater and surface water samples for 1,4-Dioxane to ensure protection of human health and the environment. A USEPA Technical Fact Sheet for 1,4-Dioxane is provided in Appendix A of this Memorandum. Solid Waste Section Limits & Laboratory Analytical Methods In 2006, the Solid Waste Section made a policy decision to develop and use Solid Waste Section Limits (SWSLs). The purpose for this policy decision was to ensure that low level analytical data was consistently being reported for the purpose of making the correct choices when designing site remediation strategies, alerting the public to health threats, and protecting the environment from toxic contaminants. Over the past 12 years, technologies have advanced such that the majority of the SWSLs are outdated. Given the rapid pace of technology, the need for the Section to attempt to continuously update and/or maintain the SWSLs is not warranted. State of North Carolina I Environmental Quality I Waste Management 217 West ]ones Street 1 I646 Mail ServiCe Center I Raleigh, NOrth Carolina 27699-1646 9l9 707 8200 Although the use of the SWSLs will be discontinued, facilities should choose EPA approved analytical methods sufficiently sensitive to quantify the presence of a pollutant at or below applicable standards. Consistently achieving low level data is key for the continued purpose of making the correct choices when designing site remediation strategies, alerting the public to health threats, and protecting the environment from toxic contaminants. Facilities should communicate and coordinate with their analytical laboratory(s) to use sufficiently sensitive analytical methods to achieve analytical results with detection limits below the applicable groundwater standards and surface water standards. For guidance purposes, the Section recommends the use of the following analytical methods for groundwater and surface water samples. Volatile Organic Compounds SW 846 Method 8260 1,4-Dioxane SW 846 Method 8260 SIM SW 846 Method 8270 SIM Semi -Volatile Organic SW 846 Method 8270 Compounds Metals, Pesticides, PCBs, SW 846 Methods, USEPA Dioxins, Cyanide, methods, or method published Formaldehyde, and any other in Standard Methods for the constituents not covered by Examination of Water and above methods Wastewater having the lowest detection limits or having detection limits below applicable standards Notes: • The analytical methods should be the most recent versions of the analytical methods tabulated above. For SW- 846 Methods, the latest edition of SW-846, including any subsequent updates which have been incorporated into the edition, must be used. Sampling must be planned so that required holding times for analytical methods are met. • Select Ion Monitoring (SIM) is recommended when analyzing for 1,4-Dioxane in order to achieve applicable detection limits. SIM may be useful for other VOCs/SVOC constituents. • SW-846 Method 1610 does not have detection limits below the 1 SA NCAC 2L standards for all of the hazardous substance list metals. • The Section considers "J" flag values valid and relevant in the decision making process and hence all "J" flag values should be reported.

EPA United States Environmental Protection Agency Technical Fact Sheet — 1,4-Dioxane January 2014 Introduction This fact sheet, developed by the U.S. Environmental Protection Agency (EPA) Federal Facilities Restoration and Reuse Office (FFRRO), provides a summary of the contaminant 1,4-dioxane, including physical and chemical properties; environmental and health impacts; existing federal and state guidelines; detection and treatment methods; and additional sources of information. This fact sheet is intended for use by site managers who may address 1,4-dioxane at cleanup sites or in drinking water supplies and for those in a position to consider whether 1,4-dioxane should be added to the analytical suite for site investigations. 1,4-Dioxane is a likely human carcinogen and has been found in groundwater at sites throughout the United States. The physical and chemical properties and behavior of 1,4-dioxane create challenges for its characterization and treatment. It is highly mobile and has not been shown to readily biodegrade in the environment. What is 1,4-dioxane? ❖ 1,4-Dioxane is a synthetic industrial chemical that is completely miscible in water (EPA 2006). ❖ Synonyms include dioxane, dioxan, p-dioxane, diethylene dioxide, diethylene oxide, diethylene ether and glycol ethylene ether (EPA 2006; Mohr 2001). ❖ 1,4-Dioxane is unstable at elevated temperatures and pressures and may form explosive mixtures with prolonged exposure to light or air (DHHS 2011; HSDB 2011). ❖ 1,4-Dioxane is a likely contaminant at many sites contaminated with certain chlorinated solvents (particularly 1,1,1-trichloroethane [TCA]) because of its widespread use as a stabilizer for chlorinated solvents (EPA 2013a; Mohr 2001) ❖ It is used as: a stabilizer for chlorinated solvents such as TCA; a solvent for impregnating cellulose acetate membrane filters; a wetting and dispersing agent in textile processes; and a laboratory cryoscopic solvent for molecular mass determinations (ATSDR 2012; DHHS 2011; EPA 2006). ❖ It is used in many products, including paint strippers, dyes, greases, varnishes and waxes. 1,4-Dioxane is also found as an impurity in antifreeze and aircraft deicing fluids and in some consumer products (deodorants, shampoos and cosmetics) (ATSDR 2012; EPA 2006; Mohr 2001). Disclaimer: The U.S. EPA prepared this fact sheet from publically-available sources; additional information can be obtained from the source documents. This fact sheet is not intended to be used as a primary source of information and is not intended, nor can it be relied upon, to create any rights enforceable by any party in litigation with the United States. Mention of trade names or commercial products does not constitute endorsement or recommendation for use. United States Office of Solid Waste and EPA 505-F-14-011 Environmental Protection Agency Emergency Response (5106P) January 2014 1 What is 1,4-dioxane? (continued) ❖ 1,4-Dioxane is used as a purifying agent in the manufacture of pharmaceuticals and is a by- product in the manufacture of polyethylene terephthalate (PET) plastic (Mohr 2001). ❖ Traces of 1,4-dioxane may be present in some food supplements, food containing residues from packaging adhesives or on food crops treated with pesticides that contain 1,4-dioxane as a solvent or inert ingredient (ATSDR 2012; DHHS 2011). Exhibit 1: Physical and Chemical Properties of 1,4-Dioxane (ATSDR 2012; Howard 1990; HSDB 2011) Property Value Abstracts Service (CAS) Number 123-91-1 Physical Description (physical state at room temperature) Clear, flammable liquid with a faint, pleasant odor Molecular weight (g/mol) 88.11 Water solubility Miscible Melting point (°C) 11.8 Boiling point (°C) at 760 mm Hg 101.1 °C Vapor pressure at 25°C (mm Hg) 38.1 Specific gravity 1.033 Octanol-water partition coefficient (log Kow) -0.27 Organic carbon partition coefficient (log Kos) 1.23 Henry's law constant at 25 °C (atm-m3/mol) 4.80 X 10-6 Abbreviations: g/mol — grams per mole; °C — degrees Celsius; mm Hg — millimeters of mercury; atm-m3/mol — atmosphere -cubic meters per mole. What are the environmental impacts of 1,4-dioxane? ❖ 1,4-Dioxane is released into the environment from surface water bodies (DHHS 2011; EPA during its production, the processing of other 2006). chemicals, its use and its generation as an impurity during the manufacture of some consumer products. It is typically found at some solvent release sites and PET manufacturing facilities (ATSDR 2012; Mohr 2001). ❖ It is short-lived in the atmosphere, with an estimated 1- to 3-day half-life as a result of its reaction with photochemically produced hydroxyl radicals (ATSDR 2012; DHHS 2011). Breakdown products include aldehydes and ketones (Graedel 1986). ❖ It may migrate rapidly in groundwater, ahead of other contaminants and does not volatilize rapidly ❖ Migration to groundwater is weakly retarded by sorption of 1,4-dioxane to soil particles; it is expected to move rapidly from soil to groundwater (EPA 2006; ATSDR 2012). It is relatively resistant to biodegradation in water and soil and does not bioconcentrate in the food chain (ATSDR 2012; Mohr 2001). As of 2007, 1,4-dioxane had been identified at more than 31 sites on the EPA National Priorities List (NPL); it may be present (but samples were not analyzed for it) at many other sites (HazDat 2007). What are the routes of exposure and the health effects of 1,4-dioxane? ❖ Potential exposure could occur during production Inhalation is the most common route of human and use of 1,4-dioxane as a stabilizer or solvent exposure, and workers at industrial sites are at (DHHS 2011). greatest risk of repeated inhalation exposure Exposure may occur through inhalation of vapors, (ATSDR 2012; DHHS 2011). ingestion of contaminated food and water or dermal contact (ATSDR 2012; DHHS 2011). What are the routes of exposure and the health effects of 1,4-dioxane? (continued) ❖ 1,4-Dioxane is readily adsorbed through the lungs and gastrointestinal tract. Some 1,4-dioxane may also pass through the skin, but studies indicate that much of it will evaporate before it is absorbed. Distribution is rapid and uniform in the lung, liver, kidney, spleen, colon and skeletal muscle tissue (ATSDR 2012). ❖ Short-term exposure to high levels of 1,4- dioxane may result in nausea, drowsiness, headache, and irritation of the eyes, nose and throat (ATSDR 2012; EPA 2013b; NIOSH 2O10) ❖ Chronic exposure may result in dermatitis, eczema, drying and cracking of skin and liver and kidney damage (ATSDR 2012; HSDB 2011). ❖ 1,4-Dioxane is weakly genotoxic and reproductive effects in humans are unknown; however, a developmental study on rats indicated that 1,4-dioxane may be slightly toxic to the developing fetus (ATSDR 2012; Giavini and others 1985). ❖ Animal studies showed increased incidences of nasal cavity, liver and gall bladder tumors after exposure to 1,4-dioxane (DHHS 2011; EPA IRIS 2013). ❖ EPA has classified 1,4-dioxane as "likely to be carcinogenic to humans" by all routes of exposure (EPA IRIS 2013). ❖ The U.S. Department of Health and Human Services states that 1,4-dioxane is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals (DHHS 2011). ❖ The American Conference of Governmental Industrial Hygienists (ACGIH) has classified 1,4-dioxane as a Group A3 carcinogen — confirmed animal carcinogen with unknown relevance to humans (ACGIH 2O11). ❖ The National Institute for Occupational Safety and Health (NIOSH) considers 1,4-dioxane a potential occupational carcinogen (NIOSH 2010). Are there any federal and state guidelines and health standards for 1,4-dioxane? ❖ Federal and State Standards and Guidelines: ■ EPA's Integrated Risk Information System (IRIS) database includes a chronic oral reference dose (RfD) of 0.03 milligrams per kilogram per day (mg/kg/day) based on liver and kidney toxicity in animals and a chronic inhalation reference dose (RfC) of 0.03 milligrams per cubic meter (mg/m3) based on atrophy and respiratory metaplasia inside the nasal cavity of animals (EPA IRIS 2013). ■ The Agency for Toxic Substances and Disease Registry (ATSDR) has established minimal risk levels (MRLs) for inhalation exposure to 1,4-dioxane : 2 parts per million (ppm) for acute -duration (14 days or less) inhalation exposure; 0.2 ppm for intermediate -duration (15 to 364 days) inhalation exposure; and 0.03 ppm for chronic -duration (365 days or more) inhalation exposure (ATSDR 2012). ■ Oral exposure MRLs have been identified as 5 mg/kg/day for acute -duration oral exposure; 0.5 mg/kg/day for intermediate - duration oral exposure; and 0.1 mg/kg/day for chronic -duration oral exposure (ATSDR 2012). • The cancer risk assessment for 1,4-dioxane is based on an oral slope factor of 0.1 mg/kg/day and the drinking water unit risk is 2.9 x 10-6 micrograms per liter (pg/L) (EPA IRIS 2013). ■ EPA risk assessments indicate that the drinkinP water concentration representing a 1 x 10- cancer risk level for 1,4-dioxane is 0.35 µg/L (EPA IRIS 2013). ■ 1,4-Dioxane may be regulated as hazardous waste when waste is generated through use as a solvent stabilizer (EPA 1996b). ■ No federal maximum contaminant level (MCL) for drinking water has been established; however, an MCL is not necessary to determine a cleanup level (EPA 2012). ■ 1,4-Dioxane was included on the third drinking water contaminant candidate list, which is a list of unregulated contaminants that are known to, or anticipated to, occur in public water systems and may require regulation under the Safe Drinking Water Act (EPA 2009). Are there any federal and state guidelines and health standards for 1,4-dioxane? (continued) ❖ Federal and State Standards and Guidelines (continued): ■ The EPA has established drinking water health advisories for 1,4-dioxane, which are drinking water -specific risk level concentrations for cancer (10-4 cancer risk) and concentrations of drinking water contaminants at which noncancer adverse health effects are not anticipated to occur over specific exposure durations. The EPA established a 1-day health advisory of 4.0 milligrams per liter (mg/L) and a 10-day health advisory of 0.4 mg/L for 1,4-dioxane in drinking water for a 10-kilogram child. EPA also established a lifetime health advisory of 0.2 mg/L for 1,4-dioxane in drinking water (EPA 2012). ■ The EPA's drinking water equivalent level for 1,4-dioxane is 1 mg/L (EPA 2012). ■ EPA has calculated a screening level of 0.67 pg/L for 1,4-dioxane in tap water, based on a 1 in 10-6 lifetime excess cancer risk (EPA 2013c). ' , 2 ■ EPA has calculated a residential soil screening level (SSL) of 4.9 milligrams per kilogram (mg/kg) and an industrial SSL of 17 mg/kg. The soil -to -groundwater risk -based SSL is 1.4 x10-4 mg/kg (EPA 2013c). ■ EPA has also calculated a residential air screening level of 0.49 micrograms per cubic meter (pg/m3) and an industrial air screening level of 2.5 pg/m3 (EPA 2013c). Screening Levels are developed using risk assessment guidance from the EPA Superfund program. These risk -based concentrations are derived from standardized equations combining exposure information assumptions with EPA toxicity data. These calculated screening levels are generic and not enforceable cleanup standards but provide a useful gauge of relative toxicity. 2 Tap water screening levels differ from the IRIS drinking water concentrations because the tap water screening levels account for dermal, inhalation and ingestion exposure routes; age -adjust the intake rates for children and adults based on body weight; and time - adjust for exposure duration or days per year. The IRIS drinking water concentrations consider only the ingestion route, account only for adult -intake rates and do not time -adjust for exposure duration or days per year. ❖ Workplace Exposure Limits: ■ The Occupational Safety and Health Administration set a general industry permissible exposure limit of 360 mg/m3 or 100 ppm based on a time -weighted average (TWA) over an 8-hour workday for airborne exposure to 1,4-dioxane (OSHA 2013). ■ The ACGIH set a threshold limit value of 72 mg/m3 or 20 ppm based on a TWA over an 8- hour workday for airborne exposure to 1,4- dioxane (ACGIH 2O11). ■ The NIOSH has set a ceiling recommended exposure limit of 3.6 mg/m3 or 1 ppm based on a 30-minute airborne exposure to 1,4-dioxane (NIOSH 2O10). ■ NIOSH also has established an immediately dangerous to life or health concentration of 500 ppm for 1,4-dioxane (NIOSH 2O10). ❖ Other State and Federal Standards and Guidelines: ■ Various states have established drinking water and groundwater guidelines, including the following: Colorado has established an interim groundwater quality cleanup standard of 0.35 pg/L (CDPHE 2012); California has established a notification level of 1 pg/L for drinking water (CDPH 2011); — New Hampshire has established a reporting limit of 0.25 pg/L for all public water supplies (NH DES 2011); and — Massachusetts has established a drinking water guideline level of 0.3 pg/L (Mass DEP 2012). • The Food and Drug Administration set 10 mg/kg as the limit for 1-4-dioxane in glycerides and polyglycerides for use in products such as dietary supplements. FDA also surveys raw material and products contaminated with 1,4-dioxane (FDA 2006). • 1,4-Dioxane is listed as a hazardous air pollutant under the Clean Air Act (CAA) (CAA 1990). ■ A reportable quantity of 100 pounds has been established under the Comprehensive Environmental Response, Compensation, and Liability Act (EPA 2011). What detection and site characterization methods are available for 1,4-dioxane? ❖ As a result of the limitations in the analytical methods to detect 1,4-dioxane, it has been difficult to identify its occurrence in the environment. The miscibility of 1,4-dioxane in water causes poor purging efficiency and results in high detection limits (ATSDR 2012; EPA 2006). ❖ Conventional analytical methods can detect 1,4-dioxane only at concentrations 100 times greater than the concentrations of volatile organic compounds (EPA 2006; Mohr 2001). ❖ Modifications of existing analytical methods and their sample preparation procedures may be needed to achieve lower detection limits for 1,4-dioxane (EPA 2006; Mohr 2001). ❖ High -temperature sample preparation techniques improve the recovery of 1,4-dioxane. These techniques include purging at elevated temperature (EPA SW-846 Method 5030); equilibrium headspace analysis (EPA SW-846 Method 5021); vacuum distillation (EPA SW-846 Method 8261); and azeotrophic distillation (EPA SW-846 Method 5031) (EPA 2006). ❖ The presence of 1,4-dioxane may be expected at sites with extensive TCA contamination; therefore, some experts recommend that groundwater samples be analyzed for 1,4-dioxane where TCA is a known contaminant (Mohr 2001). NIOSH Method 1602 uses gas chromatography — flame ionization detection (GC-FID) to determine the concentration of 1,4-dioxane in air. The detection limit is 0.01 milligram per sample (ATSDR 2012; NIOSH 2O10). ❖ EPA SW-846 Method 8015D uses gas chromatography (GC) to determine the concentration of 1,4-dioxane in environmental samples. Samples may be introduced into the GC column by a variety of techniques including the injection of the concentrate from azeotropic distillation (EPA SW-846 Method 5031). The detection limits for 1,4-dioxane in aqueous matrices by azeotropic microdistillation are 12 pg/L (reagent water), 15 pg/L (groundwater) and 16 pg/L (leachate) (EPA 2003). EPA SW-846 Method 8260B detects 1,4-dioxane in a variety of solid waste matrices using GC and mass spectrometry (MS). The detection limit depends on the instrument and choice of sample preparation method (ATSDR 2012; EPA 1996a). A laboratory study is underway to develop a passive flux meter (PFM) approach to enhance the capture of 1,4-dioxane in the PFM sorbent to improve accuracy. The selected PFM approach will be field tested at 1,4-dioxane contaminated sites. The anticipated projection completion date is 2014 (DoD SERDP 2013b). ❖ EPA Method 1624 uses isotopic dilution gas chromatography — mass spectrometry (GC -MS) to detect 1,4-dioxane in water, soil and municipal sludges. The detection limit for this method is 10 pg/L (ATSDR 2012; EPA 2001 b). ❖ EPA SW-846 Method 8270 uses liquid -liquid extraction and isotope dilution by capillary column GC -MS. This method is often modified for the detection of low levels of 1,4-dioxane in water (EPA 2007, 2013a) ❖ GC -MS detection methods using solid phase extraction followed by desorption with an organic solvent have been developed to remove 1,4-dioxane from the aqueous phase. Detection limits as low as 0.024 pg/L have been achieved by passing the aqueous sample through an activated carbon column, following by elution with acetone- dichlormethane (ATSDR 2012; Kadokami and others 1990). ❖ EPA Method 522 uses solid phase extraction and GC/MS with selected ion monitoring for the detection of 1,4-dioxane in drinking water with detection limits ranging from 0.02 to 0.026 pg/L (EPA 2008). What technologies are being used to treat 1,4-dioxane? ❖ Pump -and -treat remediation can treat dissolved 1,4-dioxane in groundwater and control groundwater plume migration, but requires ex situ treatment tailored for the unique properties of 1,4-dioxane (such as, a low octanol-water partition coefficient that makes 1,4-dioxane hydrophilic) (EPA 2006; Kiker and others 2010). ❖ Commercially available advanced oxidation processes using hydrogen peroxide with ultraviolet light or ozone is used to treat 1,4-dioxane in wastewater (Asano and others 2012; EPA 2006). ❖ A study is under way to investigate facilitated - transport enabled in situ chemical oxidation to treat 1,4-dioxane-contamined source zones and groundwater plumes effectively. The technical approach consists of the co -injection of strong oxidants (such as ozone) with chemical agents that facilitate the transport of the oxidant (DoD SERDP 2013d). What technologies are being used to treat 1,4-dioxane? (continued) ❖ Ex situ bioremediation using a fixed -film, moving - bed biological treatment system is also used to treat 1,4-dioxane in groundwater (EPA 2006). ❖ Phytoremediation is being explored as a means to remove the compound from shallow groundwater. Pilot -scale studies have demonstrated the ability of hybrid poplars to take up and effectively degrade or deactivate 1,4-dioxane (EPA 2001 a, 2013a; Ferro and others 2013). ❖ Microbial degradation in engineered bioreactors has been documented under enhanced conditions or where selected strains of bacteria capable of degrading 1,4-dioxane are cultured, but the impact of the presence of chlorinated solvent co - contaminants on biodegradation of 1,4-dioxane needs to be further investigated (EPA 2006, 2013a; Mahendra and others 2013). ❖ Results from a 2012 laboratory study found 1,4-dioxane-transforming activity to be relatively common among monooxygenase-expressing bacteria; however, both TCA and 1,1-dichloroethene inhibited 1,4-dioxane degradation by bacterial isolates (DoD SERDP 2012). ❖ Several Department of Defense Strategic Environmental Research and Development Program (DoD SERDP) projects are under way to investigate 1,4-dioxane biodegradation in the presence of chlorinated solvents or metals. Laboratory studies will (1) identify microbial cultures as well as biogeochemistry, which generate desirable enzymatic activity for 1,4-dioxane biodegradation; (2) assess biodegradation by methane oxidizing bacteria in coupled anaerobic -aerobic zones; (3) and evaluate branched hydrocarbons as stimulants for the in situ cometabolic biodegradation of 1,4-dioxane and its associated co -contaminants (DoD SERDP 2013c, a and f). ❖ Photocatalysis has been shown to remove 1,4-dioxane in aqueous solutions. Laboratory studies documented that the surface plasmon resonance of gold nanoparticles on titanium dioxide (Au — TiO2) promotes the photocatalytic degradation of 1,4-dioxane (Min and others 2009; Vescovi and others 2010). ❖ Other in -well combined treatment technologies being assessed include air sparging; soil vapor extraction (SVE); and dynamic subsurface groundwater circulation (Odah and others 2005). ❖ SVE is known to remove some 1,4-dioxane, but substantial residual contamination is usually left behind because of 1,4-dioxane's high solubility, which leads to preferential partitioning into pore water rather than vapor. The DoD SERDP is conducting a project to evaluate and demonstrate the efficacy of enhanced or extreme SVE, which uses a combination of increased air flow, sweeping with drier air, increased temperature, decreased infiltration and more focused vapor extraction to enhance 1,4-dioxane remediation in soils (DoD SERDP 2013a).

Sampling must begin with an evaluation of facility information, historical environmental data and site geologic and hydrogeologic conditions. General sampling procedures are described in this document. Planning Begin sampling activities with planning and coordination. The party contracting with the laboratory is responsible for effectively communicating reporting requirements and evaluating data reliability as it relates to specific monitoring activities. Sample Collection Contamination Prevention a.) Take special effort to prevent cross contamination or environmental contamination when collecting samples. 1. If possible, collect samples from the least contaminated sampling location (or background sampling location, if applicable) to the most contaminated sampling location. 2. Collect the ambient or background samples first, and store them in separate ice chests or separate shipping containers within the same ice chest (e.g. untreated plastic bags). 3. Collect samples in flowing water at designated locations from upstream to downstream. b.) Do not store or ship highly contaminated samples (concentrated wastes, free product, etc.) or samples suspect of containing high concentrations of contaminants in the same ice chest or shipping containers with other environmental samples. 1. Isolate these sample containers by sealing them in separate, untreated plastic bags immediately after collecting, preserving, labeling, etc. 2. Use a clean, untreated plastic bag to line the ice chest or shipping container. c.) All sampling equipment should be thoroughly decontaminated and transported in a manner that does not allow it to become contaminated. Arrangements should be made ahead of time to decontaminate any sampling or measuring equipment that will be reused when taking samples from more than one well. Field decontamination of Rev 4-08 sampling equipment will be necessary before sampling each well to minimize the risk of cross contamination. Decontamination procedures should be included in reports as necessary. Certified pre -cleaned sampling equipment and containers may be used. When collecting aqueous samples, rinse the sample collection equipment with a portion of the sample water before taking the actual sample. Sample containers do not need to be rinsed. In the case of petroleum hydrocarbons, oil and grease, or containers with pre -measured preservatives, the sample containers cannot be rinsed. d.) Place all fuel -powered equipment away from, and downwind of, any site activities (e.g., purging, sampling, decontamination). 1. If field conditions preclude such placement (i.e., the wind is from the upstream direction in a boat), place the fuel source(s) as far away as possible from the sampling activities and describe the conditions in the field notes. 2. Handle fuel (i.e., filling vehicles and equipment) prior to the sampling day. If such activities must be performed during sampling, the personnel must wear disposable gloves. 3. Dispense all fuels downwind. Dispose of gloves well away from the sampling activities. Filling Out Sample Labels Fill out label, adhere to vial and collect sample. Print legibly with indelible ink. At a minimum, the label or tag should identify the sample with the following information: 1. Sample location and/or well number 2. Sample identification number 3. Date and time of collection 4. Analysis required/requested 5. Sampler's initials 6. Preservative(s) used, if any [i.e., HCI, Na2S203, NO3, ice, etc.] 7. Any other pertinent information for sample identification Sample Collection Order Unless field conditions justify other sampling regimens, collect samples in the following order: 1. Volatile Organics and Volatile Inorganics 2. Extractable Organics, Petroleum Hydrocarbons, Aggregate Organics and Oil and Grease 3. Total Metals 4. Inorganic Nonmetallics, Physical and Aggregate Properties, and Biologicals 5. Microbiological NOTE: If the pump used to collect groundwater samples cannot be used to collect volatile or extractable organics then collect all other parameters and withdraw the pump and tubing. Then collect the volatile and extractable organics. Rev 4-08 Health and Safety Implement all local, state, and federal requirements relating to health and safety. Follow all local, state and federal requirements pertaining to the storage and disposal of any hazardous or investigation derived wastes. a.) The Solid Waste Section recommends wearing protective gloves when conducting all sampling activities. 1. Gloves serve to protect the sample collector from potential exposure to sample constituents, minimize accidental contamination of samples by the collector, and preserve accurate tare weights on preweighed sample containers. 2. Do not let gloves come into contact with the sample or with the interior or lip of the sample container. Use clean, new, unpowdered and disposable gloves. Various types of gloves may be used as long as the construction materials do not contaminate the sample or if internal safety protocols require greater protection. 3. Note that certain materials that may potentially be present in concentrated effluent can pass through certain glove types and be absorbed in the skin. Many vendor catalogs provide information about the permeability of different gloves and the circumstances under which the glove material might be applicable. The powder in powdered gloves can contribute significant contamination. Powdered gloves are not recommended unless it can be demonstrated that the powder does not interfere with the sample analysis. 4. Change gloves after preliminary activities, after collecting all the samples at a single sampling point, if torn or used to handle extremely dirty or highly contaminated surfaces. Properly dispose of all used gloves as investigation derived wastes. b.) Properly manage all investigation derived waste (IDW). 5. To prevent contamination into previously uncontaminated areas, properly manage all IDW. This includes all water, soil, drilling mud, decontamination wastes, discarded personal protective equipment (PPE), etc. from site investigations, exploratory borings, piezometer and monitoring well installation, refurbishment, abandonment, and other investigative activities. Manage all IDW that is determined to be RCRA-regulated hazardous waste according to the local, state and federal requirements. 6. Properly dispose of IDW that is not a RCRA-regulated hazardous waste but is contaminated above the Department's Soil Cleanup Target Levels or the state standards and/or minimum criteria for ground water quality. If the drill cuttings/mud orpurged well water is contaminated with hazardous waste, contact the DWM Hazardous Waste Section (919-508-8400) for disposal options. Maintain all containers holding IDW in good condition. Periodically inspect the containers for damage and ensure that all required labeling (DOT, RCRA, etc.) are clearly visible. Rev 4-08 Sample Storage and Transport Store samples for transport carefully. Pack samples to prevent from breaking and to maintain a temperature of approximately 4 degrees Celsius (°C), adding ice if necessary. Transport samples to a North Carolina -certified laboratory as soon as possible. Avoid unnecessary handling of sample containers. Avoid heating (room temperature or above, including exposure to sunlight) or freezing of the sample containers. Reduce the time between sample collection and delivery to a laboratory whenever possible and be sure that the analytical holding times of your samples can be met by the laboratory. a.) A complete chain -of -custody (COC) form must be maintained to document all transfers and receipts of the samples. Be sure that the sample containers are labeled with the sample location and/or well number, sample identification, the date and time of collection, the analysis to be performed, the preservative added (if any), the sampler's initials, and any other pertinent information for sample identification. The labels should contain a unique identifier (i.e., unique well numbers) that can be traced to the COC form. The details of sample collection must be documented on the COC. The COC must include the following: 1. Description of each sample (including QA/QC samples) and the number of containers (sample location and identification) 2. Signature of the sampler 3. Date and time of sample collection 4. Analytical method to be performed 5. Sample type (i.e., water or soil) 6. Regulatory agency (i.e., NCDENR/DWM — SW Section) 7. Signatures of all persons relinquishing and receiving custody of the samples 8. Dates and times of custody transfers b.) Pack samples so that they are segregated by site, sampling location or by sample analysis type. When COC samples are involved, segregate samples in coolers by site. If samples from multiple sites will fit in one cooler, they may be packed in the same cooler with the associated field sheets and a single COC form for all. Coolers should not exceed a maximum weight of 50 lbs. Use additional coolers as necessary. All sample containers should be placed in plastic bags (segregated by analysis and location) and completely surrounded by ice. 1. Prepare and place trip blanks in an ice filled cooler before leaving for the field. 2. Segregate samples by analysis and place in sealable plastic bags. 3. Pack samples carefully in the cooler placing ice around the samples. 4. Review the COC. The COC form must accompany the samples to the laboratory. The trip blank(s) must also be recorded on the COC form. 5. Place completed COC form in a waterproof bag, sealed and taped under the lid of the cooler. 6. Secure shipping containers with strapping tape to avoid accidental opening. 7. For COC samples, a tamper -proof seal may also be placed over the cooler lid or over a bag or container containing the samples inside the shipping cooler. Rev 4-08 4 8. "COC" or "EMERG" should be written in indelible ink on the cooler seal to alert sample receipt technicians to priority or special handling samples. 9. The date and sample handler's signature must also be written on the COC seal. 10. Deliver the samples to the laboratory or ship by commercial courier. NOTE: If transport time to the laboratory is not long enough to allow samples to be cooled to 4° C, a temperature reading of the sample source must be documented as the field temperature on the CDC form. A downward trend in temperature will be adequate even if cooling to 4° C is not achieved. The field temperature should always be documented if there is any question as to whether samples will have time to cool to 4° C during shipment. Thermometers must be calibrated annually against an NIST traceable thermometer and documentation must be retained. Rev 4-08 Appendix A - Decontamination of Field Equipment Decontamination of personnel, sampling equipment, and containers - before and after sampling - must be used to ensure collection of representative samples and to prevent the potential spread of contamination. Decontamination of personnel prevents ingestion and absorption of contaminants. It must be done with a soap and water wash and deionized or distilled water rinse. Certified pre -cleaned sampling equipment and containers may also be used. All previously used sampling equipment must be properly decontaminated before sampling and between sampling locations. This prevents the introduction of contamination into uncontaminated samples and avoids cross -contamination of samples. Cross -contamination can be a significant problem when attempting to characterize extremely low concentrations of organic compounds or when working with soils that are highly contaminated. Clean, solvent -resistant gloves and appropriate protective equipment must be worn by persons decontaminating tools and equipment. Cleaning Reagents Recommendations for the types and grades of various cleaning supplies are outlined below. The recommended reagent types or grades were selected to ensure that the cleaned equipment is free from any detectable contamination. a.) Detergents: Use Liqui-Nox (or a non -phosphate equivalent) or Alconox (or equivalent). Liqui-Nox (or equivalent) is recommended by EPA, although Alconox (or equivalent) may be substituted if the sampling equipment will not be used to collect phosphorus or phosphorus containing compounds. b.) Solvents: Use pesticide grade isopropanol as the rinse solvent in routine equipment cleaning procedures. This grade of alcohol must be purchased from a laboratory supply vendor. Rubbing alcohol or other commonly available sources of isopropanol are not acceptable. Other solvents, such as acetone or methanol, may be used as the final rinse solvent if they are pesticide grade. However, methanol is more toxic to the environment and acetone may be an analyte of interest for volatile organics. 1. Do not use acetone if volatile organics are of interest 2. Containerize all methanol wastes (including rinses) and dispose as a hazardous waste. Pre -clean equipment that is heavily contaminated with organic analytes. Use reagent grade acetone and hexane or other suitable solvents. Use pesticide grade methylene chloride when cleaning sample containers. Store all solvents away from potential sources of contamination. c.) Analyte-Free Water Sources: Analyte-free water is water in which all analytes of interest and all interferences are below method detection limits. Maintain documentation (such as results from equipment blanks) to demonstrate the reliability and purity of analyte-free water source(s). The source of the water must meet the requirements of the analytical method and must be free from the analytes of interest. In general, the following water types are associated with specific analyte groups: 1. Milli-Q (or equivalent polished water): suitable for all analyses. Rev 4-08 2. Organic free: suitable for volatile and extractable organics. 3. Deionized water: may not be suitable for volatile and extractable organics. 4. Distilled water: not suitable for volatile and extractable organics, metals or ultratrace metals. Use analyte-free water for blank preparation and the final decontamination water rinse. In order to minimize long-term storage and potential leaching problems, obtain or purchase analyte-free water just prior to the sampling event. If obtained from a source (such as a laboratory), fill the transport containers and use the contents for a single sampling event. Empty the transport container(s) at the end of the sampling event. Discard any analyte-free water that is transferred to a dispensing container (such as a wash bottle or pump sprayer) at the end of each sampling day. d.) Acids: 1. Reagent Grade Nitric Acid: 10 - 15% (one volume concentrated nitric acid and five volumes deionized water). Use for the acid rinse unless nitrogen components (e.g., nitrate, nitrite, etc.) are to be sampled. If sampling for ultra -trace levels of metals, use an ultra -pure grade acid. 2. Reagent Grade Hydrochloric Acid: 10% hydrochloric acid (one volume concentrated hydrochloric and three volumes deionized water). Use when nitrogen components are to be sampled. 3. If samples for both metals and the nitrogen -containing components are collected with the equipment, use the hydrochloric acid rinse, or thoroughly rinse with hydrochloric acid after a nitric acid rinse. If sampling for ultra trace levels of metals, use an ultra -pure grade acid. 4. Freshly prepared acid solutions may be recycled during the sampling event or cleaning process. Dispose of any unused acids according to local ordinances. Reagent Storage Containers The contents of all containers must be clearly marked. a.) Detergents: 1. Store in the original container or in a HDPE or PP container. b.) Solvents: 1. Store solvents to be used for cleaning or decontamination in the original container until use in the field. If transferred to another container for field use, use either a glass or Teflon container. 2. Use dispensing containers constructed of glass, Teflon or stainless steel. Note: If stainless steel sprayers are used, any gaskets that contact the solvents must be constructed of inert materials. c.) Analyte-Free Water: 1. Transport in containers appropriate for the type of water stored. If the water is commercially purchased (e.g., grocery store), use the original containers when transporting the water to the field. Containers made of glass, Teflon, polypropylene or HDPE are acceptable. 2. Use glass or Teflon to transport organic -free sources of water on -site. Polypropylene or HDPE may be used, but are not recommended. Rev 4-08 7 3. Dispense water from containers made of glass, Teflon, HDPE or polypropylene. 4. Do not store water in transport containers for more than three days before beginning a sampling event. 5. If working on a project that has oversight from EPA Region 4, use glass containers for the transport and storage of all water. 6. Store and dispense acids using containers made of glass, Teflon or plastic. General Requirements a.) Prior to use, clean/decontaminate all sampling equipment (pumps, tubing, lanyards, split spoons, etc.) that will be exposed to the sample. b.) Before installing, clean (or obtain as certified pre -cleaned) all equipment that is dedicated to a single sampling point and remains in contact with the sample medium (e.g., permanently installed groundwater pump). If you use certified pre -cleaned equipment no cleaning is necessary. 1. Clean this equipment any time it is removed for maintenance or repair. 2. Replace dedicated tubing if discolored or damaged. c.) Clean all equipment in a designated area having a controlled environment (house, laboratory, or base of field operations) and transport it to the field, pre -cleaned and ready to use, unless otherwise justified. d.) Rinse all equipment with water after use, even if it is to be field -cleaned for other sites. Rinse equipment used at contaminated sites or used to collect in -process (e.g., untreated or partially treated wastewater) samples immediately with water. e.) Whenever possible, transport sufficient clean equipment to the field so that an entire sampling event can be conducted without the need for cleaning equipment in the field. f.) Segregate equipment that is only used once (i.e., not cleaned in the field) from clean equipment and return to the in-house cleaning facility to be cleaned in a controlled environment. g.) Protect decontaminated field equipment from environmental contamination by securely wrapping and sealing with one of the following: 1. Aluminum foil (commercial grade is acceptable) 2. Untreated butcher paper 3. Clean, untreated, disposable plastic bags. Plastic bags may be used for all analyte groups except volatile and extractable organics. Plastic bags may be used for volatile and extractable organics, if the equipment is first wrapped in foil or butcher paper, or if the equipment is completely dry. Cleaning Sample Collection Equipment a.) On-Site/In-Field Cleaning — Cleaning equipment on -site is not recommended because environmental conditions cannot be controlled and wastes (solvents and acids) must be containerized for proper disposal. 1. Ambient temperature water may be substituted in the hot, sudsy water bath and hot water rinses. NOTE: Properly dispose of all solvents and acids. Rev 4-08 2. Rinse all equipment with water after use, even if it is to be field -cleaned for other sites. 3. Immediately rinse equipment used at contaminated sites or used to collect in -process (e.g., untreated or partially treated wastewater) samples with water. b.) Heavily Contaminated Equipment - In order to avoid contaminating other samples, isolate heavily contaminated equipment from other equipment and thoroughly decontaminate the equipment before further use. Equipment is considered heavily contaminated if it: 1. Has been used to collect samples from a source known to contain significantly higher levels than background. 2. Has been used to collect free product. 3. Has been used to collect industrial products (e.g., pesticides or solvents) or their byproducts. NOTE: Cleaning heavily contaminated equipment in the field is not recommended. c.) On -Site Procedures: 1. Protect all other equipment, personnel and samples from exposure by isolating the equipment immediately after use. 2. At a minimum, place the equipment in a tightly sealed, untreated, plastic bag. 3. Do not store or ship the contaminated equipment next to clean, decontaminated equipment, unused sample containers, or filled sample containers. 4. Transport the equipment back to the base of operations for thorough decontamination. 5. If cleaning must occur in the field, document the effectiveness of the procedure, collect and analyze blanks on the cleaned equipment. d.) Cleaning Procedures: 1. If organic contamination cannot be readily removed with scrubbing and a detergent solution, pre -rinse equipment by thoroughly rinsing or soaking the equipment in acetone. 2. Use hexane only if preceded and followed by acetone. 3. In extreme cases, it may be necessary to steam clean the field equipment before proceeding with routine cleaning procedures. 4. After the solvent rinses (and/or steam cleaning), use the appropriate cleaning procedure. Scrub, rather than soak, all equipment with sudsy water. If high levels of metals are suspected and the equipment cannot be cleaned without acid rinsing, soak the equipment in the appropriate acid. Since stainless steel equipment should not be exposed to acid rinses, do not use stainless steel equipment when heavy metal contamination is suspected or present. 5. If the field equipment cannot be cleaned utilizing these procedures, discard unless further cleaning with stronger solvents and/or oxidizing solutions is effective as evidenced by visual observation and blanks. 6. Clearly mark or disable all discarded equipment to discourage use. Rev 4-08 e.) General Cleaning - Follow these procedures when cleaning equipment under controlled conditions. Check manufacturer's instructions for cleaning restrictions and/or recommendations. 1. Procedure for Teflon, stainless steel and glass sampling equipment: This procedure must be used when sampling for ALL analyte groups. (Extractable organics, metals, nutrients, etc. or if a single decontamination protocol is desired to clean all Teflon, stainless steel and glass equipment.) Rinse equipment with hot tap water. Soak equipment in a hot, sudsy water solution (Liqui-Nox or equivalent). If necessary, use a brush to remove particulate matter or surface film. Rinse thoroughly with hot tap water. If samples for trace metals or inorganic analytes will be collected with the equipment that is not stainless steel, thoroughly rinse (wet all surfaces) with the appropriate acid solution. Rinse thoroughly with analyte-free water. Make sure that all equipment surfaces are thoroughly flushed with water. If samples for volatile or extractable organics will be collected, rinse with isopropanol. Wet equipment surfaces thoroughly with free - flowing solvent. Rinse thoroughly with analyte-free water. Allow to air dry. Wrap and seal as soon as the equipment has air-dried. If isopropanol is used, the equipment may be air-dried without the final analyte-free water rinse; however, the equipment must be completely dry before wrapping or use. Wrap clean sampling equipment according to the procedure described above. 2. General Cleaning Procedure for Plastic Sampling Equipment: Rinse equipment with hot tap water. Soak equipment in a hot, sudsy water solution (Liqui-Nox or equivalent). If necessary, use a brush to remove particulate matter or surface film. Rinse thoroughly with hot tap water. Thoroughly rinse (wet all surfaces) with the appropriate acid solution. Check manufacturer's instructions for cleaning restrictions and/or recommendations. Rinse thoroughly with analyte-free water. Be sure that all equipment surfaces are thoroughly flushed. Allow to air dry as long as possible. Wrap clean sampling equipment according to the procedure described above. Rev 4-08 10 Appendix B - Collecting Soil Samples Soil samples are collected for a variety of purposes. A methodical sampling approach must be used to assure that sample collection activities provide reliable data. Sampling must begin with an evaluation of background information, historical data and site conditions. Soil Field Screening Procedures Field screening is the use of portable devices capable of detecting petroleum contaminants on a real-time basis or by a rapid field analytical technique. Field screening should be used to help assess locations where contamination is most likely to be present. When possible, field -screening samples should be collected directly from the excavation or from the excavation equipment's bucket. If field screening is conducted only from the equipment's bucket, then a minimum of one field screening sample should be collected from each 10 cubic yards of excavated soil. If instruments or other observations indicate contamination, soil should be separated into stockpiles based on apparent degrees of contamination. At a minimum, soil suspected of contamination must be segregated from soil observed to be free of contamination. a.) Field screening devices — Many field screen instruments are available for detecting contaminants in the field on a rapid or real-time basis. Acceptable field screening instruments must be suitable for the contaminant being screened. The procdedure for field screening using photoionization detectors (PIDs) and flame ionization detectors (FIDs) is described below. If other instruments are used, a description of the instrument or method and its intended use must be provided to the Solid Waste Section. Whichever field screening method is chosen, its accuracy must be verified throughout the sampling process. Use appropriate standards that match the use intended for the data. Unless the Solid Waste Section indicates otherwise, wherever field screening is recommended in this document, instrumental or analytical methods of detection must be used, not olfactory or visual screening methods. b.) Headspace analytical screening procedure for filed screening (semi -quantitative field screening) - The most commonly used field instruments for Solid Waste Section site assessments are FIDs and PIDs. When using FIDs and PIDs, use the following headspace screening procedure to obtain and analyze field -screening samples: 1. Partially fill (one-third to one-half) a clean jar or clean ziplock bag with the sample to be analyzed. The total capacity of the jar or bag may not be less than eight ounces (app. 250 ml), but the container should not be so large as to allow vapor diffusion and stratification effects to significantly affect the sample. 2. If the sample is collected from a spilt -spoon, it must be transferred to the jar or bag for headspace analysis immediately after opening the split - spoon. If the sample is collected from an excavation or soil pile, it must be collected from freshly uncovered soil. Rev 4-08 11 3. If a jar is used, it must be quickly covered with clean aluminum foil or a jar lid; screw tops or thick rubber bands must be used to tightly seal the jar. If a zip lock bag is used, it must be quickly sealed shut. 4. Headspace vapors must be allowed to develop in the container for at least 10 minutes but no longer than one hour. Containers must be shaken or agitated for 15 seconds at the beginning and the end of the headspace development period to assist volatilization. Temperatures of the headspace must be warmed to at least 5° C (approximately 40' F) with instruments calibrated for the temperature used. 5. After headspace development, the instrument sampling probe must be inserted to a point about one-half the headspace depth. The container opening must be minimized and care must be taken to avoid the uptake of water droplets and soil particulates. 6. After probe insertion, the highest meter reading must be taken and recorded. This will normally occur between two and five seconds after probe insertion. If erratic meter response occurs at high organic vapor concentrations or conditions of elevated headspace moisture, a note to that effect must accompany the headspace data. 7. All field screening results must be documented in the field record or log book. Soil Sample Collection Procedures for Laboratory Samples The number and type of laboratory samples collected depends on the purpose of the sampling activity. Samples analyzed with field screening devices may not be substituted for required laboratory samples. a.) General Sample Collection - When collecting samples from potentially contaminated soil, care should be taken to reduce contact with skin or other parts of the body. Disposable gloves should be worn by the sample collector and should be changed between samples to avoid cross -contamination. Soil samples should be collected in a manner that causes the least disturbance to the internal structure of the sample and reduces its exposure to heat, sunlight and open air. Likewise, care should be taken to keep the samples from being contaminated by other materials or other samples collected at the site. When sampling is to occur over an extended period of time, it is necessary to insure that the samples are collected in a comparable manner. All samples must be collected with disposable or clean tools that have been decontaminated. Disposable gloves must be worn and changed between sample collections. Sample containers must be filled quickly. Soil samples must be placed in containers in the order of volatility, for example, volatile organic aromatic samples must be taken first, organics next, then heavier range organics, and finally soil classification samples. Containers must be quickly and adequately sealed, and rims must be cleaned before tightening lids. Tape may be used only if known not to affect sample analysis. Sample containers must be clearly labeled. Containers must immediately be preserved according to procedures in this Section. Unless specified Rev 4-08 12 otherwise, at a minimum, the samples must be immediately cooled to 4 ± 2°C and this temperature must be maintained throughout delivery to the laboratory. b.) Surface Soil Sampling - Surface soil is generally classified as soil between the ground surface and 6-12 inches below ground surface. Remove leaves, grass and surface debris from the area to be sampled. Select an appropriate, pre -cleaned sampling device and collect the sample. Transfer the sample to the appropriate sample container. Clean the outside of the sample container to remove excess soil. Label the sample container, place on wet ice to preserve at 4°C, and complete the field notes. c.) Subsurface Soil Sampling — The interval begins at approximately 12 inches below ground surface. Collect samples for volatile organic analyses. For other analyses, select an appropriate, pre -cleaned sampling device and collect the sample. Transfer the sample to the appropriate sample container. Clean the outside of the sample container to remove excess soil. Label the sample container, place on wet ice to preserve at 4°C, and complete field notes. d.) Equipment for Reachingthe Appropriate Soil Sampling Depth - Samples may be collected using a hollow stem soil auger, direct push, Shelby tube, split -spoon sampler, or core barrel. These sampling devices may be used as long as an effort is made to reduce the loss of contaminants through volatilization. In these situations, obtain a sufficient volume of so the samples can be collected without volatilization and disturbance to the internal structure of the samples. Samples should be collected from cores of the soil. Non -disposable sampling equipment must be decontaminated between each sample location. NOTE: If a confining layer has been breached during sampling, grout the hole to land. e.) Equipment to Collect Soil Samples - Equipment and materials that may be used to collect soil samples include disposable plastic syringes and other "industry -standard" equipment and materials that are contaminant -free. Non -disposable sampling equipment must be decontaminated between each sample location. Rev 4-08 13 Appendix C - Collecting Groundwater Samples Groundwater samples are collected to identify, investigate, assess and monitor the concentration of dissolved contaminant constituents. To properly assess groundwater contamination, first install sampling points (monitoring wells, etc.) to collect groundwater samples and then perform specific laboratory analyses. All monitoring wells should be constructed in accordance with 15A NCAC 2C .0100 and sampled as outlined in this section. Groundwater monitoring is conducted using one of two methods: 1. Portable Monitoring: Monitoring that is conducted using sampling equipment that is discarded between sampling locations. Equipment used to collect a groundwater sample from a well such as bailers, tubing, gloves, and etc. are disposed of after sample collection. A new set of sampling equipment is used to collect a groundwater sample at the next monitor well. 2. Dedicated Monitoriniz: Monitoring that utilizes permanently affixed down -well and well head components that are capped after initial set-up. Most dedicated monitoring systems are comprised of an in -well submersible bladder pump, with air supply and sample discharge tubing, and an above -ground driver/controller for regulation of flow rates and volumes. The pump and all tubing housed within the well should be composed of Teflon or stainless steel components. This includes seals inside the pump, the pump body, and fittings used to connect tubing to the pump. Because ground water will not be in contact with incompatible constituents and because the well is sealed from the surface, virtually no contamination is possible from intrinsic sources during sampling and between sampling intervals. All dedicated monitoring systems must be approved by the Solid Waste Section before installation. Groundwater samples may be collected from a number of different configurations. Each configuration is associated with a unique set of sampling equipment requirements and techniques: 1. Wells without Plumbing: These wells require equipment to be brought to the well to purge and sample unless dedicated equipment is placed in the well. 2. Wells with In -Place Plumbing: Wells with in -place plumbing do not require equipment to be brought to the well to purge and sample. In -place plumbing is generally considered permanent equipment routinely used for purposes other than purging and sampling, such as for water supply. 3. Air Strippers or Remedial Systems: These types of systems are installed as remediation devices. Rev 4-08 14 Groundwater Sample Preparation The type of sample containers used depends on the type of analysis performed. First, determine the type(s) of contaminants expected and the proper analytical method(s). Be sure to consult your selected laboratory for its specific needs and requirements prior to sampling. Next, prepare the storage and transport containers (ice chest, etc.) before taking any samples so that each sample can be placed in a chilled environment immediately after collection. Use groundwater purging and sampling equipment constructed of only non -reactive, non - leachable materials that are compatible with the environment and the selected analytes. In selecting groundwater purging and sampling equipment, give consideration to the depth of the well, the depth to groundwater, the volume of water to be evacuated, the sampling and purging technique, and the analytes of interest. Additional supplies, such as reagents and preservatives, may be necessary. All sampling equipment (bailers, tubing, containers, etc.) must be selected based on its chemical compatibility with the source being sampled (e.g., water supply well, monitoring well) and the contaminants potentially present. a.) Pumps - All pumps or pump tubing must be lowered and retrieved from the well slowly and carefully to minimize disturbance to the formation water. This is especially critical at the air/water interface. 1. Above -Ground Pumps • Variable Speed Peristaltic Pump: Use a variable speed peristaltic pump to purge groundwater from wells when the static water level in the well is no greater than 20- 25 feet below land surface (BLS). If the water levels are deeper than 18-20 feet BLS, the pumping velocity will decrease. A variable speed peristaltic pump can be used for normal purging and sampling, and sampling low permeability aquifers or formations. Most analyte groups can be sampled with a peristaltic pump if the tubing and pump configurations are appropriate. • Variable Speed Centrifugal Pump: A variable speed centrifugal pump can be used to purge groundwater from 2-inch and larger internal diameter wells. Do not use this type of pump to collect groundwater samples. When purging is complete, do not allow the water that remains in the tubing to fall back into the well. Install a check valve at the end of the purge tubing. 2. Submersible Pumps • Variable Speed Electric Submersible Pump: A variable speed submersible pump can be used to purge and sample groundwater from 2-inch and larger internal diameter wells. A variable speed submersible pump can be used for normal purging and sampling, and sampling low permeability aquifers or formations. The pump housing, fittings, check valves and associated hardware must be constructed of stainless steel. All other materials must be Rev 4-08 15 b.) Bailers compatible with the analytes of interest. Install a check valve at the output side of the pump to prevent backflow. If purging and sampling for organics, the entire length of the delivery tube must be Teflon, polyethylene or polypropylene (PP) tubing; the electrical cord must be sealed in Teflon, polyethylene or PP and any cabling must be sealed in Teflon, polyethylene or PP, or be constructed of stainless steel; and all interior components that contact the sample water (impeller, seals, gaskets, etc.) must be constructed of stainless steel or Teflon. 3. Variable Speed Bladder Pump: A variable speed, positive displacement, bladder pump can be used to purge and sample groundwater from 3/4-inch and larger internal diameter wells. • A variable speed bladder pump can be used for normal purging and sampling, and sampling low permeability aquifers or formations. • The bladder pump system is composed of the pump, the compressed air tubing, the water discharge tubing, the controller and a compressor, or a compressed gas supply. • The pump consists of a bladder and an exterior casing or pump body that surrounds the bladder and two (2) check valves. These parts can be composed of various materials, usually combinations of polyvinyl chloride (PVC), Teflon, polyethylene, PP and stainless steel. Other materials must be compatible with the analytes of interest. • If purging and sampling for organics, the pump body must be constructed of stainless steel. The valves and bladder must be Teflon, polyethylene or PP; the entire length of the delivery tube must be Teflon, polyethylene or PP; and any cabling must be sealed in Teflon, polyethylene or PP, or be constructed of stainless steel. • Permanently installed pumps may have a PVC pump body as long as the pump remains in contact with the water in the well. I. Purging: Bailers must be used with caution because improper bailing can cause changes in the chemistry of the water due to aeration and loosening particulate matter in the space around the well screen. Use a bailer if there is non -aqueous phase liquid (free product) in the well or if non -aqueous phase liquid is suspected to be in the well. 2. Sampling: Bailers must be used with caution. 3. Construction and Type: Bailers must be constructed of materials compatible with the analytes of interest. Stainless steel, Teflon, rigid medical grade PVC, polyethylene and PP bailers may be used to sample all analytes. Use disposable bailers when sampling grossly contaminated sample sources. NCDENR recommends using dual check valve bailers when collecting samples. Use bailers with a controlled flow bottom to collect volatile organic samples. Rev 4-08 16 4. Contamination Prevention: Keep the bailer wrapped (foil, butcher paper, etc.) until just before use. Use protective gloves to handle the bailer once it is removed from its wrapping. Handle the bailer by the lanyard to minimize contact with the bailer surface. c.) Lans 1. Lanyards must be made of non -reactive, non -leachable material. They may be cotton twine, nylon, stainless steel, or may be coated with Teflon, polyethylene or PP. 2. Discard cotton twine, nylon, and non -stainless steel braided lanyards after sampling each monitoring well. 3. Decontaminate stainless steel, coated Teflon, polyethylene and PP lanyards between monitoring wells. They do not need to be decontaminated between purging and sampling operations. Water Level and Purge Volume Determination The amount of water that must be purged from a well is determined by the volume of water and/or field parameter stabilization. a.) General Equipment Considerations - Selection of appropriate purging equipment depends on the analytes of interest, the well diameter, transmissivity of the aquifer, the depth to groundwater, and other site conditions. 1. Use of a pump to purge the well is recommended unless no other equipment can be used or there is non -aqueous phase liquid in the well, or non -aqueous phase liquid is suspected to be in the well. 2. Bailers must be used with caution because improper bailing: • Introduces atmospheric oxygen, which may precipitate metals (i.e., iron) or cause other changes in the chemistry of the water in the sample (i.e., pH). • Agitates groundwater, which may bias volatile and semi - volatile organic analyses due to volatilization. • Agitates the water in the aquifer and resuspends fine particulate matter. • Surges the well, loosening particulate matter in the annular space around the well screen. • May introduce dirt into the water column if the sides of the casing wall are scraped. NOTE: It is critical for bailers to be slowly and gently immersed into the top of the water column, particularly during the final stages of purging. This minimizes turbidity and disturbance of volatile organic constituents. b.) Initial Inspection 1. Remove the well cover and remove all standing water around the top of the well casing (manhole) before opening the well. 2. Inspect the exterior protective casing of the monitoring well for damage. Document the results of the inspection if there is a problem. 3. It is recommended that you place a protective covering around the well head. Replace the covering if it becomes soiled or ripped. Rev 4-08 17 4. Inspect the well lock and determine whether the cap fits tightly. Replace the cap if necessary. c.) Water Level Measurements - Use an electronic probe or chalked tape to determine the water level. Decontaminate all equipment before use. Measure the depth to groundwater from the top of the well casing to the nearest 0.01 foot. Always measure from the same reference point or survey mark on the well casing. Record the measurement. I. Electronic Probe: Decontaminate all equipment before use. Follow the manufacturer's instructions for use. Record the measurement. 2. Chalked Line Method: Decontaminate all equipment before use. Lower chalked tape into the well until the lower end is in the water. This is usually determined by the sound of the weight hitting the water. Record the length of the tape relative to the reference point. Remove the tape and note the length of the wetted portion. Record the length. Determine the depth to water by subtracting the length of the wetted portion from the total length. Record the result. d.) Water Column Determination - To determine the length of the water column, subtract the depth to the top of the water column from the total well depth (or gauged well depth if silting has occurred). The total well depth depends on the well construction. If gauged well depth is used due to silting, report total well depth also. Some wells may be drilled in areas of sinkhole, karst formations or rock leaving an open borehole. Attempt to find the total borehole depth in cases where there is an open borehole below the cased portion. e.) Well Water Volume - Calculate the total volume of water, in gallons, in the well using the following equation: V = (0.041)d x d x h Where: V = volume in gallons d = well diameter in inches h = height of the water column in feet The total volume of water in the well may also be determined with the following equation by using a casing volume per foot factor (Gallons per Foot of Water) for the appropriate diameter well: V = [Gallons per Foot of Water] x h Where: V = volume in gallons h = height of the water column in feet Record all measurements and calculations in the field records. f.) Purging Equipment Volume - Calculate the total volume of the pump, associated tubing and flow cell (if used), using the following equation: V= p + ((0.041)d x dx 1)+fc Where: V = volume in gallons p = volume of pump in gallons d = tubing diameter in inches 1= length of tubing in feet Rev 4-08 18 fc = volume of flow cell in gallons g.) If the groundwater elevation data are to be used to construct groundwater elevation contour maps, all water level measurements must be taken within the same 24 hour time interval when collecting samples from multiple wells on a site, unless a shorter time period is required. If the site is tidally influenced, complete the water level measurements within the time frame of an incoming or outgoing tide. Well Purging Techniques The selection of the purging technique and equipment is dependent on the hydrogeologic properties of the aquifer, especially depth to groundwater and hydraulic conductivity. a.) Measuring the Purge Volume - The volume of water that is removed during purging must be recorded. Therefore, you must measure the volume during the purging operation. 1. Collect the water in a graduated container and multiply the number of times the container was emptied by the volume of the container, OR 2. Estimate the volume based on pumping rate. This technique may be used only if the pumping rate is constant. Determine the pumping rate by measuring the amount of water that is pumped for a fixed period of time, or use a flow meter. • Calculate the amount of water that is discharged per minute: D = Measured Amount/Total Time In Minutes • Calculate the time needed to purge one (1) well volume or one (1) purging equipment volume: Time = V/D Where: V = well volume or purging equipment volume D = discharge rate • Make new measurements each time the pumping rate is changed. 3. Use a totalizing flow meter. • Record the reading on the totalizer prior to purging. • Record the reading on the totalizer at the end of purging. • To obtain the volume purged, subtract the reading on the totalizer prior to purging from the reading on the totalizer at the end of purging. • Record the times that purging begins and ends in the field records. b.) Purging Measurement Frequency - When purging a well that has the well screen fully submerged and the pump or intake tubing is placed within the well casing above the well screen or open hole, purge a minimum of one (1) well volume prior to collecting measurements of the field parameters. Allow at least one quarter (1/4) well volume to purge between subsequent measurements. When purging a well that has the pump or intake tubing placed within a fully submerged well screen or open hole, purge until the water level has stabilized (well recovery rate equals the purge rate), then purge a minimum of one (1) volume of the pump, associated tubing and flow cell (if used) prior to collecting measurements of the field parameters. Take measurements of the field parameters no sooner than two (2) to three (3) minutes apart. Purge at least Rev 4-08 19 three (3) volumes of the pump, associated tubing and flow cell, if used, prior to collecting a sample. When purging a well that has a partially submerged well screen, purge a minimum of one (1) well volume prior to collecting measurements of the field parameters. Take measurements of the field parameters no sooner than two (2) to three (3) minutes apart. c.) Purging ompletion - Wells must be adequately purged prior to sample collection to ensure representation of the aquifer formation water, rather than stagnant well water. This may be achieved by purging three volumes from the well or by satisfying any one of the following three purge completion criteria: 1.) Three (3) consecutive measurements in which the three (3) parameters listed below are within the stated limits, dissolved oxygen is no greater than 20 percent of saturation at the field measured temperature, and turbidity is no greater than 20 Nephelometric Turbidity Units (NTUs). • Temperature: + 0.2° C • pH: + 0.2 Standard Units • Specific Conductance: + 5.0% of reading Document and report the following, as applicable. The last four items only need to be submitted once: • Purging rate. • Drawdown in the well, if any. • A description of the process and the data used to design the well. • The equipment and procedure used to install the well. • The well development procedure. • Pertinent lithologic or hydrogeologic information. 2.) If it is impossible to get dissolved oxygen at or below 20 percent of saturation at the field measured temperature or turbidity at or below 20 NTUs, then three (3) consecutive measurements of temperature, pH, specific conductance and the parameter(s) dissolved oxygen and/or turbidity that do not meet the requirements above must be within the limits below. The measurements are: • Temperature: + 0.2° C • pH: + 0.2 Standard Units • Specific Conductance: + 5.0% of reading • Dissolved Oxygen: + 0.2 mg/L or 10%, whichever is greater • Turbidity: + 5 NTUs or 10%, whichever is greater Additionally, document and report the following, as applicable, except that the last four(4) items only need to be submitted once: • Purging rate. • Drawdown in the well, if any. • A description of conditions at the site that may cause the dissolved oxygen to be high and/or dissolved oxygen measurements made within the screened or open hole portion of the well with a downhole dissolved oxygen probe. Rev 4-08 20 • A description of conditions at the site that may cause the turbidity to be high and any procedures that will be used to minimize turbidity in the future. • A description of the process and the data used to design the well. • The equipment and procedure used to install the well. • The well development procedure. • Pertinent lithologic or hydrogeologic information. 3.) If after five (5) well volumes, three (3) consecutive measurements of the field parameters temperature, pH, specific conductance, dissolved oxygen, and turbidity are not within the limits stated above, check the instrument condition and calibration, purging flow rate and all tubing connections to determine if they might be affecting the ability to achieve stable measurements. It is at the discretion of the consultant/contractor whether or not to collect a sample or to continue purging. Further, the report in which the data are submitted must include the following, as applicable. The last four (4) items only need to be submitted once. • Purging rate. • Drawdown in the well, if any. • A description of conditions at the site that may cause the Dissolved Oxygen to be high and/or Dissolved Oxygen measurements made within the screened or open hole portion of the well with a downhole dissolved oxygen probe. • A description of conditions at the site that may cause the turbidity to be high and any procedures that will be used to minimize turbidity in the future. • A description of the process and the data used to design the well. • The equipment and procedure used to install the well. • The well development procedure. • Pertinent lithologic or hydrogeologic information. If wells have previously and consistently purged dry, and the current depth to groundwater indicates that the well will purge dry during the current sampling event, minimize the amount of water removed from the well by using the same pump to purge and collect the sample: • Place the pump or tubing intake within the well screened interval. • Use very small diameter Teflon, polyethylene or PP tubing and the smallest possible pump chamber volume. This will minimize the total volume of water pumped from the well and reduce drawdown. • Select tubing that is thick enough to minimize oxygen transfer through the tubing walls while pumping. Rev 4-08 21 • Pump at the lowest possible rate (100 mL/minute or less) to reduce drawdown to a minimum. • Purge at least two (2) volumes of the pumping system (pump, tubing and flow cell, if used). • Measure pH, specific conductance, temperature, dissolved oxygen and turbidity, then begin to collect the samples. Collect samples immediately after purging is complete. The time period between completing the purge and sampling cannot exceed six hours. If sample collection does not occur within one hour of purging completion, re -measure the five field parameters: temperature, pH, specific conductance, dissolved oxygen and turbidity, just prior to collecting the sample. If the measured values are not within 10 percent of the previous measurements, re -purge the well. The exception is "dry" wells. d.) Lanyards 1. Securely fasten lanyards, if used, to any downhole equipment (bailers, pumps, etc.). 2. Use bailer lanyards in such a way that they do not touch the ground surface. Wells Without Plumbing a.) Tubin /gip Placement 1. If attempting to minimize the volume of purge water, position the intake hose or pump at the midpoint of the screened or open hole interval. 2. If monitoring well conditions do not allow minimizing of the purge water volume, position the pump or intake hose near the top of the water column. This will ensure that all stagnant water in the casing is removed. 3. If the well screen or borehole is partially submerged, and the pump will be used for both purging and sampling, position the pump midway between the measured water level and the bottom of the screen. Otherwise, position the pump or intake hose near the top of the water column. b.) Non -dedicated (portable) pumps 1.

Bailers - Using bailers for purging is not recommended unless care is taken to use proper bailing technique, or if free product is present in the well or suspected to be in the well. • Minimize handling the bailer as much as possible. • Wear sampling gloves. • Remove the bailer from its protective wrapping just before use. • Attach a lanyard of appropriate material. • Use the lanyard to move and position the bailer. • Lower and retrieve the bailer slowly and smoothly. • Lower the bailer carefully into the well to a depth approximately a foot above the water column. • When the bailer is in position, lower the bailer into the water column at a rate of 2 cm/sec until the desired depth is reached. • Do not lower the top of the bailer more than one (1) foot below the top of the water table so that water is removed from the top of the water column. • Allow time for the bailer to fill with aquifer water as it descends into the water column. Rev 4-08 25 • Carefully raise the bailer. Retrieve the bailer at the same rate of 2 cm/sec until the bottom of the bailer has cleared to top of the water column. • Measure the purge volume. • Record the volume of the bailer. • Continue to carefully lower and retrieve the bailer as described above until the purging is considered complete, based on either the removal of 3 well volumes. • Remove at least one (1) well volume before collecting measurements of the field parameters. Take each subsequent set of measurements after removing at least one quarter (1/4) well volume between measurements. Groundwater Sampling Techniques a.) Purge wells. b.) Replace protective covering around the well if it is soiled or torn after completing purging operations. c.) Equipment Considerations 1. The following pumps are approved to collect volatile organic samples: • Stainless steel and Teflon variable speed submersible PUMPS • Stainless steel and Teflon or polyethylene variable speed bladder pumps • Permanently installed PVC bodied pumps (As long as the pump remains in contact with the water in the well at all times) 2. Collect sample from the sampling device and store in sample container. Do not use intermediate containers. 3. To avoid contamination or loss of analytes from the sample, handle sampling equipment as little as possible and minimize equipment exposure to the sample. 4. To reduce chances of cross -contamination, use dedicated equipment whenever possible. "Dedicated" is defined as equipment that is to be used solely for one location for the life of that equipment (e.g., permanently mounted pump). Purchase dedicated equipment with the most sensitive analyte of interest in mind. • Clean or make sure dedicated pumps are clean before installation. They do not need to be cleaned prior to each use, but must be cleaned if they are withdrawn for repair or servicing. • Clean or make sure any permanently mounted tubing is clean before installation. • Change or clean tubing when the pump is withdrawn for servicing. • Clean any replaceable or temporary parts. Rev 4-08 26 • Collect equipment blanks on dedicated pumping systems when the tubing is cleaned or replaced. • Clean or make sure dedicated bailers are clean before placing them into the well. • Collect an equipment blank on dedicated bailers before introducing them into the water column. • Suspend dedicated bailers above the water column if they are stored in the well. Sampling Wells Without Plumbing a.) Sampling with Pumps — The following pumps may be used to sample for organics: • Peristaltic pumps • Stainless steel, Teflon or polyethylene bladder pumps • Variable speed stainless steel and Teflon submersible PUMPS Peristaltic Pump • Volatile Organics: One of three methods may be used. ■ Remove the drop tubing from the inlet side of the pump; submerge the drop tubing into the water column; prevent the water in the tubing from flowing back into the well; remove the drop tubing from the well; carefully allow the groundwater to drain into the sample vials; avoid turbulence; do not aerate the sample; repeat steps until enough vials are filled. OR ■ Use the pump to fill the drop tubing; quickly remove the tubing from the pump; prevent the water in the tubing from flowing back into the well; remove the drop tubing from the well; carefully allow the groundwater to drain into the sample vials; avoid turbulence; do not aerate the sample; repeat steps until enough vials are filled. OR ■ Use the pump to fill the drop tubing; withdraw the tubing from the well; reverse the flow on the peristaltic pumps to deliver the sample into the vials at a slow, steady rate; repeat steps until enough vials are filled. • Extractable Organics: If delivery tubing is not polyethylene or PP, or is not Teflon lined, use pump and vacuum trap method. Connect the outflow tubing from the container to the influent side of the peristaltic pump. Turn pump on and reduce flow until smooth and even. Discard a Rev 4-08 27 small portion of the sample to allow for air space. Preserve (if required), label, and complete field notes. • Inorganic samples: These samples may be collected from the effluent tubing. If samples are collected from the pump, decontaminate all tubing (including the tubing in the head) or change it between wells. Preserve (if required), label, and complete field notes. 2. Variable Speed Bladder Pump • If sampling for organics, the pump body must be constructed of stainless steel and the valves and bladder must be Teflon. All tubing must be Teflon, polyethylene, or PP and any cabling must be sealed in Teflon, polyethylene or PP, or made of stainless steel. • After purging to a smooth even flow, reduce the flow rate. • When sampling for volatile organic compounds, reduce the flow rate to 100-200mL/minute, if possible. 3. Variable Speed Submersible Pump • The housing must be stainless steel. • If sampling for organics, the internal impellers, seals and gaskets must be constructed of stainless steel, Teflon, polyethylene or PP. The delivery tubing must be Teflon, polyethylene or PP; the electrical cord must be sealed in Teflon; any cabling must be sealed in Teflon or constructed of stainless steel. • After purging to a smooth even flow, reduce the flow rate. • When sampling for volatile organic compounds, reduce the flow rate to 100-200mL/minute, if possible. b.) Sampling with Bailers - A high degree of skill and coordination are necessary to collect representative samples with a bailer. 1. General Considerations • Minimize handling of bailer as much as possible. • Wear sampling gloves. • Remove bailer from protective wrapping just before use. • Attach a lanyard of appropriate material. • Use the lanyard to move and position the bailers. • Do not allow bailer or lanyard to touch the ground. • If bailer is certified precleaned, no rinsing is necessary. • If both a pump and a bailer are to be used to collect samples, rinse the exterior and interior of the bailer with sample water from the pump before removing the pump. • If the purge pump is not appropriate for collecting samples (e.g., non -inert components), rinse the bailer by collecting a single bailer of the groundwater to be sampled. • Discard the water appropriately. Rev 4-08 28 • Do not rinse the bailer if Oil and Grease samples are to be collected. 2. Bailing Technique • Collect all samples that are required to be collected with a pump before collecting samples with the bailer. • Raise and lower the bailer gently to minimize stirring up particulate matter in the well and the water column, which can increase sample turbidity. • Lower the bailer carefully into the well to a depth approximately a foot above the water column. When the bailer is in position, lower the bailer into the water column at a rate of 2 cm/sec until the desired depth is reached. • Do not lower the top of the bailer more than one foot below the top of the water table, so that water is removed from the top of the water column. • Allow time for the bailer to fill with aquifer water as it descends into the water column. • Do not allow the bailer to touch the bottom of the well or particulate matter will be incorporated into the sample. Carefully raise the bailer. Retrieve the bailer at the same rate of 2 cm/sec until the bottom of the bailer has cleared to top of the water column. • Lower the bailer to approximately the same depth each time. • Collect the sample. Install a device to control the flow from the bottom of the bailer and discard the first few inches of water. Fill the appropriate sample containers by allowing the sample to slowly flow down the side of the container. Discard the last few inches of water in the bailer. • Repeat steps for additional samples. • As a final step measure the DO, pH, temperature, turbidity and specific conductance after the final sample has been collected. Record all measurements and note the time that sampling was completed. c.) Sampling Low Permeability Aquifers or Wells that have Purged D 1. Collect the sample(s) after the well has been purged. Minimize the amount of water removed from the well by using the same pump to purge and collect the sample. If the well has purged dry, collect samples as soon as sufficient sample water is available. 2. Measure the five field parameters temperature, pH, specific conductance, dissolved oxygen and turbidity at the time of sample collection. 3. Advise the analytical laboratory and the client that the usual amount of sample for analysis may not be available. Rev 4-08 29 Appendix D - Collecting Samples from Wells with Plumbing in Place In -place plumbing is generally considered permanent equipment routinely used for purposes other than purging and sampling, such as for water supply. a.) Air Strippers or Remedial Systems - These types of systems are installed as remediation devices. Collect influent and effluent samples from air stripping units as described below. 1. Remove any tubing from the sampling port and flush for one to two minutes. 2. Remove all hoses, aerators and filters (if possible). 3. Open the spigot and purge sufficient volume to flush the spigot and lines and until the purging completion criteria have been met. 4. Reduce the flow rate to approximately 500 mUminute (a 1/8" stream) or approximately 0.1 gal/minute before collecting samples. 5. Follow procedures for collecting samples from water supply wells as outlined below. b.) Water Supply Wells — Water supply wells with in -place plumbing do not require equipment to be brought to the well to purge and sample. Water supply wells at UST facilities must be sampled for volatile organic compounds (VOCs) and semivolatile compounds (SVOCs). 1. Procedures for Sampling Water Supply Wells • Label sample containers prior to sample collection. • Prepare the storage and transport containers (ice chest, etc.; before taking any samples so each collected sample can be placed in a chilled environment immediately after collection. • You must choose the tap closest to the well, preferably at the wellhead. The tap must be before any holding or pressurization tank, water softener, ion exchange, disinfection process or before the water line enters the residence, office or building. If no tap fits the above conditions, a new tap that does must be installed. • The well pump must not be lubricated with oil, as that may contaminate the samples. • The sampling tap must be protected from exterior contamination associated with being too close to a sink bottom or to the ground. If the tap is too close to the ground for direct collection into the appropriate container, it is acceptable to use a smaller (clean) container to transfer the sample to a larger container. • Leaking taps that allow water to discharge from around the valve stem handle and down the outside of the faucet, or taps in which water tends to run up on the outside of the lip, are to be avoided as sampling locations. Rev 4-08 30 • Disconnect any hoses, filters, or aerators attached to the tap before sampling. • Do not sample from a tap close to a gas pump. The gas fumes could contaminate the sample. 2. Collecting Volatile Organic Samples • Equipment Needed: VOC sample vials [40 milliliters, glass, may contain 3 to 4 drops of hydrochloric acid (HCl) as preservative]; Disposable gloves and protective goggles; Ice chest/cooler; Ice; Packing materials (sealable plastic bags, bubble wrap, etc.); and Lab forms. • Sampling Procedure: Run water from the well for at least 15 minutes. If the well is deep, run water longer (purging three well volumes is best). If tap or spigot is located directly before a holding tank, open a tap after the holding tank to prevent any backflow into the tap where you will take your sample. This will ensure that the water you collect is "fresh" from the well and not ftom the holding tank. After running the water for at least 15 minutes, reduce the flow of water. The flow should be reduced to a trickle but not so slow that it begins to drip. A smooth flow of water will make collection easier and more accurate. Remove the cap of a VOC vial and hold the vial under the stream of water to fill it. Be careful not to spill any acid that is in the vial. For best results use a low flow of water and angle the vial slightly so that the water runs down the inside of the vial. This will help keep the sample ftom being agitated, aerated or splashed out of the vial. It will also increase the accuracy of the sample. As the vial fills and is almost full, turn the vial until it is straight up and down so the water won't spill out. Fill the vial until the water is just about to spill over the lip of the vial. The surface of the water sample should become mounded. It is a good idea not to overfill the vial, especially if an acid preservative is present in the vial. Carefully replace and screw the cap onto the vial. Some water may overflow as the cap is put on. After the cap is secure, turn the vial upside down and gently tap the vial to see if any bubbles are present. If bubbles are present in the vial, remove the cap, add more water and check again to see if bubbles are present. Repeat as necessary. After two samples without bubbles have been collected, the samples should be labeled and prepared for shipment. Store samples at 4° C. Rev 4-08 31 3. Collecting Extractable Organic and/or Metals Samples • Equipment Needed: SVOC sample bottle [1 liter, amber glass] and/or Metals sample bottle [0.5 liter, polyethylene or glass, 5 milliliters of nitric acid (HNO3) preservative]; Disposable gloves and protective goggles; Ice Chest/Cooler; Ice; Packing materials (sealable plastic bags, bubble wrap, etc.); and Lab forms. • Sampling Procedure: Run water from the well for at least 15 minutes. If the well is deep, run the water longer (purging three well volumes is best). If tap or spigot is located directly before a holding tank, open a tap after the holding tank to prevent any backflow into the tap where you will take your sample. This will ensure that the water you collect is "fresh" from the well and not from the holding tank. After running the water for at least 15 minutes, reduce the flow. Low water flow makes collection easier and more accurate. Remove the cap of a SVOC or metals bottle and hold it under the stream of water to fill it. The bottle does not have to be completely filled (i.e., you can leave an inch or so of headspace in the bottle). After filling, screw on the cap, label the bottle and prepare for shipment. Store samples at 4° C. Rev 4-08 32 Appendix E - Collecting Surface Water Samples The following topics include 1.) acceptable equipment selection and equipment construction materials and 2.) standard grab, depth -specific and depth-composited surface water sampling techniques. Facilities which contain or border small rivers, streams or branches should include surface water sampling as part of the monitoring program for each sampling event. A simple procedure for selecting surface water monitoring sites is to locate a point on a stream where drainage leaves the site. This provides detection of contamination through, and possibly downstream of, site via discharge of surface waters. The sampling points selected should be downstream from any waste areas. An upstream sample should be obtained in order to determine water quality upstream of the influence of the site. a.) General Cautions 1. When using watercraft take samples near the bow away and upwind from any gasoline outboard engine. Orient watercraft so that bow is positioned in the upstream direction. 2. When wading, collect samples upstream from the body. Avoid disturbing sediments in the immediate area of sample collection. 3. Collect water samples prior to taking sediment samples when obtaining both from the same area (site). 4. Unless dictated by permit, program or order, sampling at or near man- made structures (e.g., dams, weirs or bridges) may not provide representative data because of unnatural flow patterns. 5. Collect surface water samples from downstream towards upstream. b.) Equipment and Supplies - Select equipment based on the analytes of interest, specific use, and availability. c.) Surface Water Sampling Techniques - Adhere to all general protocols applicable to aqueous sampling when following the surface water sampling procedures addressed below. 1. Manual Sampling: Use manual sampling for collecting grab samples for immediate in -situ field analyses. Use manual sampling in lieu of automatic equipment over extended periods of time for composite sampling, especially when it is necessary to observe and/or note unusual conditions. • Surface Grab Samples - Do not use sample containers containing premeasured amounts of preservatives to collect grab samples. If the sample matrix is homogeneous, then the grab method is a simple and effective technique for collection purposes. If homogeneity is not apparent, based on flow or vertical variations (and should never be assumed), then use other collection protocols. Where practical, use the actual sample container submitted to the laboratory for collecting samples to be analyzed for oil and grease, volatile organic compounds (VOCs), and microbiological samples. This procedure eliminates the possibility of contaminating the sample with an intermediate collection container. The use of Rev 4-08 33 unpreserved sample containers as direct grab samplers is encouraged since the same container can be submitted for laboratory analysis after appropriate preservation. This procedure reduces sample handling and eliminates potential contamination from other sources (e.g., additional sampling equipment, environment, etc.). 1. Grab directly into sample container. 2. Slowly submerge the container, opening neck first, into the water. 3. Invert the bottle so the neck is upright and pointing towards the direction of water flow (if applicable). Allow water to run slowly into the container until filled. 4. Return the filled container quickly to the surface. 5. Pour out a few mL of sample away from and downstream of the sampling location. This procedure allows for the addition of preservatives and sample expansion. Do not use this step for volatile organics or other analytes where headspace is not allowed in the sample container. 6. Add preservatives, securely cap container, label, and complete field notes. If sample containers are attached to a pole via a clamp, submerge the container and follow steps 3 — 5 but omit steps I and 2. • Sampling with an Intermediate Vessel or Container: If the sample cannot be collected directly into the sample container to be submitted to the laboratory, or if the laboratory provides prepreserved sample containers, use an unpreserved sample container or an intermediate vessel (e.g., beakers, buckets or dippers) to obtain the sample. These vessels must be constructed appropriately, including any poles or extension arms used to access the sample location. I. Rinse the intermediate vessel with ample amounts of site water prior to collecting the first sample. 2. Collect the sample as outlined above using the intermediate vessel. 3. Use pole mounted containers of appropriate construction to sample at distances away from shore, boat, etc. Follow the protocols above to collect samples. • Peristaltic Pump and Tubing: The most portable pump for this technique is a 12 volt peristaltic pump. Use appropriately precleaned, silastic tubing in the pump head and attach polyethylene, Tygon, etc. tubing to the pump. This technique is not acceptable for Oil and Grease, EPH, VPH or VOCs. Extractable organics can be collected through the pump if flexible interior -wall Teflon, polyethylene or PP tubing is used in the pump head or if used with the organic trap setup. Rev 4-08 34 1. Lower appropriately precleaned tubing to a depth of 6 — 12 inches below water surface, where possible. 2. Pump 3 — 5 tube volumes through the system to acclimate the tubing before collecting the first sample. 3. Fill individual sample bottles via the discharge tubing. Be careful not to remove the inlet tubing from the water. 4. Add preservatives, securely cap container, label, and complete field notes. Mid -Depth Grab Samples: Mid -depth samples or samples taken at a specific depth can approximate the conditions throughout the entire water column. The equipment that may be used for this type of sampling consists of the following depth -specific sampling devices: Kemmerer, Niskin, Van Dorn type, etc. You may also use pumps with tubing or double check -valve bailers. Certain construction material details may preclude its use for certain analytes. Many Kemmerer samplers are constructed of plastic and rubber that preclude their use for all volatile and extractable organic sampling. Some newer devices are constructed of stainless steel or are all Teflon or Teflon -coated. These are acceptable for all analyte groups without restriction. 1. Measure the water column to determine maximum depth and sampling depth prior to lowering the sampling device. 2. Mark the line attached to the sampler with depth increments so that the sampling depth can be accurately recorded. 3. Lower the sampler slowly to the appropriate sampling depth, taking care not to disturb the sediments. 4. At the desired depth, send the messenger weight down to trip the closure mechanism. 5. Retrieve the sampler slowly. 6. Rinse the sampling device with ample amounts of site water prior to collecting the first sample. Discard rinsate away from and downstream of the sampling location. 7. Fill the individual sample bottles via the discharge tube. Double Check -Valve Bailers: Collect samples using double check - valve bailers if the data requirements do not necessitate a sample from a strictly discrete interval of the water column. Bailers with an upper and lower check -valve can be lowered through the water column. Water will continually be displaced through the bailer until the desired depth is reached, at which point the bailer is retrieved. Sampling with this type of bailer must follow the same protocols outlined above, except that a messenger weight is not applicable. Although not designed specifically for this kind of sampling, a bailer is acceptable when a mid -depth sample is required Rev 4-08 35 1. As the bailer is dropped through the water column, water is displaced through the body of the bailer. The degree of displacement depends upon the check -valve ball movement to allow water to flow freely through the bailer body. 2. Slowly lower the bailer to the appropriate depth. Upon retrieval, the two check valves seat, preventing water from escaping or entering the bailer. 3. Rinse the sampling device with ample amounts of site water prior to collecting the first sample. 4. Fill the individual sample bottles via the discharge tube. Sample bottles must be handled as described above. Peristaltic Pump and Tubing: The most portable pump for this technique is a 12 volt peristaltic pump. Use appropriately precleaned, silastic tubing in the pump head and attach HDPE, Tygon, etc. tubing to the pump. This technique is not acceptable for Oil and Grease, EPH, VPH or VOCs. Extractable organics can be collected through the pump if flexible interior -wall Teflon, polyethylene or PP tubing is used in the pump head, or if used with an organic trap setup. 1. Measure the water column to determine the maximum depth and the sampling depth. 2. Tubing will need to be tied to a stiff pole or be weighted down so the tubing placement will be secure. Do not use a lead weight. Any dense, non -contaminating, non - interfering material will work (brick, stainless steel weight, etc.). Tie the weight with a lanyard (braided or monofilament nylon, etc.) so that it is located below the inlet of the tubing. 3. Turn the pump on and allow several tubing volumes of water to be discharged before collecting the first sample. 4. Fill the individual sample bottles via the discharge tube. Sample bottles must be handled as described above.

The updated guidelines are in large part due to questions and concerns from laboratories, consultants, and the regulated community regarding the detection of constituents in groundwater at levels below the previous Practical Quantitation Limits (PQLs). The North Carolina Solid Waste Section solicited feedback from the regulated community, and, in conjunction with the regulated community, developed new limits. The primary purpose of these changes was to improve the protection of public health and the environment. Data must be reported to the laboratory specific method detection limits and must be quantifiable at or below the SWSLs. The SWSLs must be used for both groundwater and surface water data reported to the North Carolina Solid Waste Section. The PQLs will no longer be used. In June 2007, we received new information regarding changes to the Groundwater Protection Standards. If a North Carolina 2L Groundwater Standard does not exist, then a designated Groundwater Protection Standard is used pursuant to 15A NCAC 13B .1634. Toxicologists with the North Carolina Department of Health and Human Services calculated these new Groundwater Protection Standards. Questions regarding how the standards were calculated can be directed to the North Carolina Department of Health and Human Services. 1646 Mail Service Center, Raleigh, North Carolina 27699-1646 Phone 919-508-84001 FAX 919-715-36051 Internet http://wastenotnc.org 1 An Equal Opportunity / Affirmative Action Employer— Printed on Dual Purpose Recycled Paper We have reviewed the new results from the North Carolina Department of Public Health and have updated our webpage accordingly.

Ross Jr., Secretary To: Solid Waste Directors, Landfill Operators, North Carolina Certified Laboratories, and Consultants From: North Carolina Division of Waste Management, Solid Waste Section Re: Addendum to October 27, 2006, North Carolina Solid Waste Section Memorandum Regarding New Guidelines for Electronic Submittal of Environmental Data. The purpose of this addendum memorandum is to provide further clarification to the October 27, 2006, North Carolina Solid Waste Section memo titled, "New Guidelines for Electronic Submittal of Environmental Data." The updated guidelines is in large part due to questions and concerns from laboratories, consultants, and the regulated community regarding the detection of constituents in groundwater at levels below the previous practical quantitation limits (PQLs). The North Carolina Solid Waste Section solicited feedback from the regulated community, and, in conjunction with the regulated community, developed new limits. The primary purpose of these changes was to improve the protection of public health and the environment. The North Carolina Solid Waste Section is concerned about analytical data at these low levels because the earliest possible detection of toxic or potentially carcinogenic chemicals in the environment is paramount in the North Carolina Solid Waste Section's mission to protect human health and the environment. Low level analytical data are critical for making the correct choices when designing site remediation strategies, alerting the public to health threats, and protecting the environment from toxic contaminants. The revised limits were updated based on readily available laboratory analytical methodology and current health -based groundwater protection standards. Definitions Many definitions relating to detection limits and quantitation limits are used in the literature and by government agencies, and commonly accepted procedures for calculating these limits exist. Except for the Solid Waste Section Limit and the North Carolina 2L Standards, the definitions listed below are referenced from the Environmental Protection Agency (EPA). The definitions are also an attempt to clarify the meaning of these terms as used by the North Carolina Solid Waste Section. Method Detection Limit (MDL) is the minimum concentration of a substance that can be measured and reported with 99% confidence that the analyte concentration is greater than zero. Method Reporting Limit or Method Quantitation Limit (MRL or MQL) is the minimum concentration of a target analyte that can be accurately determined by the referenced method. 1646 Mail Service Center, Raleigh, North Carolina 27699-1646 Phone 919-508-84001 FAX 919-715-36051 Internet http://wastenotnc.org An Equal Opportunity / Affirmative Action Employer— Printed on Dual Purpose Recycled Paper Practical Quantitation Limit (PQL) is a quantitation limit that represents a practical and routinely achievable quantitation limit with a high degree of certainty (>99.9% confidence) in the results. Per EPA Publication Number SW-846, the PQL is the lowest concentration that can be reliably measured within specified limits of precision and accuracy for a specific laboratory analytical method during routine laboratory operating conditions in accordance with "Test Methods for Evaluating Solid Wastes, Physical/Chemical Methods. The PQL appears in older NCDENR literature; however, it is no longer being used by the North Carolina Solid Waste Section. Solid Waste Section Limit (SWSL) is the lowest amount of analyte in a sample that can be quantitatively determined with suitable precision and accuracy. The SWSL is the concentration below which reported analytical results must be qualified as estimated. The SWSL is the updated version of the PQL that appears in older North Carolina Solid Waste Section literature. The SWSL is the limit established by the laboratory survey conducted by the North Carolina Solid Waste Section. The nomenclature of the SWRL described in the October 27, 2006, memorandum has changed to the SWSL. North Carolina 2L Standards (2L) are water quality standards for the protection of groundwaters of North Carolina as specified in 15A NCAC 2L .0200, Classifications and Water Quality Standards Applicable to the Groundwaters of North Carolina. Method Detection Limits (MDLs) Clarification of detection limits referenced in the October 27, 2006, memorandum needed to be addressed because of concerns raised by the regulated community. The North Carolina Solid Waste Section is now requiring laboratories to report to the method detection limit. Method detection limits are statistically determined values that define the concentration at which measurements of a substance by a specific analytical protocol can be distinguished from measurements of a blank (background noise). Method detection limits are matrix -specific and require a well defined analytical method. In the course of routine operations, laboratories generally report the highest method detection limit for all the instruments used for a specific method. In many instances, the North Carolina Solid Waste Section gathers data from many sources prior to evaluating the data or making a compliance decision. Standardization in data reporting significantly enhances the ability to interpret and review data because the reporting formats are comparable. Reporting a method detection limit alerts data users of the known uncertainties and limitations associated with using the data. Data users must understand these limitations in order to minimize the risk of making poor environmental decisions. Censoring data below unspecified or non -statistical reporting limits severely biases data sets and restricts their usefulness. Solid Waste Section Limits (SWSLs Due to comments from the regulated community, the North Carolina Solid Waste Section has changed the nomenclature of the new limits referenced on Page 2 of the October 27, 2006, memorandum, from the North Carolina Solid Waste Reporting Limits (SWRL) to the Solid Waste Section Limits (SWSL). Data must be reported to the laboratory specific method detection limits and must be quantifiable at or below the SWSL. The SWSLs must be used for both groundwater and surface water data reported to the North Carolina Solid Waste Section. The PQLs will no longer be used. 1646 Mail Service Center, Raleigh, North Carolina 27699-1646 2 Phone 919-508-84001 FAX 919-715-36051 Internet http://wastenotnc.org An Equal Opportunity / Affirmative Action Employer— Printed on Dual Purpose Recycled Paper The North Carolina Solid Waste Section has considered further feedback from laboratories and the regulated community and has made some additional changes to the values of the SWSLs. These changes may be viewed on our webpage: http://www.wastenotnc.org/sw/swenvmonitoringlist.asp Analytical Data Reporting Requirements The strategy for implementing the new analytical data reporting requirements involves reporting the actual laboratory method detection limit with all analytical laboratory results along with the following requirements: 1) Any analyte detected at a concentration greater than the MDL but less than the SWSL is known to be present, but the uncertainty in the value is higher than a value reported above the SWSL. As a result, the actual concentration is estimated. The estimated concentration is reported along with a qualifier ("J" flag) to alert data users that the result is between the MDL and the SWSL. Any analytical data below quantifiable levels should be examined closely to evaluate whether the analytical data should be included in any statistical analysis. A statistician should make this determination. If an analyte is detected below the North Carolina 2L Standards, even if it is a quantifiable concentration, compliance action may not be taken unless it is statistically significant increase over background. These analytical results may require additional confirmation. 2) Any analyte detected at a concentration greater than the SWSL is present, and the quantitated value can be reported with a high degree of confidence. These analytes are reported without estimated qualification. The laboratory's MDL and SWSL must be included in the analytical laboratory report. Any reported concentration of an organic or inorganic constituent at or above the North Carolina 2L Standards will be used for compliance purposes, unless the inorganic constituent is not statistically significant). Exceedance of the North Carolina 2L Standards or a statistically significant increase over background concentrations define when a violation has occurred. Any reported concentration of an organic or inorganic constituent at or above the SWSL that is not above an North Carolina 2L Standard will be used as a tool to assess the integrity of the landfill system and predict the possibility that a constituent concentration may exceed the North Carolina 2L Standards in the future. These analytical results may be used for compliance without further confirmation. Failure to comply with the requirements described in the October 27, 2006, memorandum and this addendum to the October 27, 2006, memorandum will constitute a violation of 15A NCAC 13B .0601, .0602, or .1632(b), and the analytical data will be returned and deemed unacceptable. Submittal of unacceptable data may lead to enforcement action. Electronic Data Deliverable (EDD) Submittal The North Carolina Solid Waste Section would also like to take this opportunity to encourage electronic submittal of the reports in addition to the analytical laboratory data.

Matthews, Director Division of Waste Management Michael F. Easley, Governor William G. Ross Jr., Secretary October 27, 2006 To: SW Director/County Manager/Consultant/Laboratory From: NC DENR-DWM, Solid Waste Section Re: New Guidelines for Electronic Submittal of Environmental Monitoring Data The Solid Waste Section receives and reviews a wide variety of environmental monitoring data from permitted solid waste management facilities, including the results from groundwater and surface water analyses, leachate samples, methane gas readings, potentiometric measurements, and corrective action data. We are in the process of developing a database to capture the large volume of data submitted by facilities. To maintain the integrity of the database, it is critical that facilities, consultants, and laboratories work with the Solid Waste Section to ensure that environmental samples are collected and analyzed properly with the resulting data transferred to the Solid Waste Section in an accurate manner. In order to better serve the public and to expedite our review process, the Solid Waste Section is requesting specific formatting for environmental monitoring data submittals for all solid waste management facilities. Effective, December 1, 2006, please submit a Solid Waste Environmental Monitoring Data Form in addition to your environmental monitoring data report. This form will be sent in lieu of your current cover letter to the Solid Waste Section. The Solid Waste Environmental Monitoring Data Form must be filled out completely, signed, and stamped with a Board Certified North Carolina Geologist License Seal. The solid waste environmental monitoring data form will include the following: 1. Contact Information 2. Facility Name 3. Facility Permit Number 4. Facility Address 5.

The Solid Waste Environmental Monitoring Data Form can be downloaded from our website: hllp://www.wastenotnc.org/swhome/enviro monitoring.asp. The Solid Waste Section is also requesting a new format for monitoring wells, potable wells, surface water sampling locations, and methane probes. This format is essential in the development and maintenance of the database. The Solid Waste Section is requesting that each sampling location at all North Carolina solid waste management facilities have its own unique identification number. We are simply asking for the permit number to be placed directly in front of the sampling location number (example: 9901-MW1 = Permit Number 99-01 and Monitoring Well MW-1). No changes will need to be made to the well tags, etc. This unique identification system will enable us to accurately report data not only to NCDENR, but to the public as well. We understand that this new identification system will take some time to implement, but we feel that this will be beneficial to everyone involved in the long term. Additionally, effective December 1, 2006, the Practical Quantitation Limits (PQLs) established in 1994 will change. The Solid Waste Section is requiring that all solid waste management facilities use the new Solid Waste Reporting Limits (SWRL) for all groundwater analyses by a North Carolina Certified Laboratory. Laboratories must also report any detection of a constituent even it is detected below the new SWRL (e.g., J values where the constituent was detected above the detection limit, but below the quantitation limit). PQLs are technology -based analytical levels that are considered achievable using the referenced analytical method. The PQL is considered the lowest concentration of a contaminant that the lab can accurately detect and quantify. PQLs provided consistency and available numbers that were achievable by the given analytical method. However, PQLs are not health -based, and analytical instruments have improved over the years resulting in lower achievable PQLs for many of the constituents. As a result, the Solid Waste Section has established the SWRLs as the new reporting limits eliminating the use of the PQLs. We would also like to take this opportunity to encourage electronic submittal of the reports. This option is intended to save resources for both the public and private sectors. The Solid Waste Section will accept the entire report including narrative text, figures, tables, and maps on CD-ROM. The CD-ROM submittal shall contain a CD-ROM case and both CD-ROM and the case shall be labeled with the site name, site address, permit number, and the monitoring event date (MM/DD/YYYY). The files maybe a .pdf, .txt, .csv, .xls, or .doc type. Also, analytical lab data should be reported in an .xls file. We have a template for analytical lab data available on the web at the address listed above. If you have any questions or concerns, please call (919) 508-8400.
