Ju1y 26, 1990 Charlotte, North Carolina Facility INTRODUCTION Central Transport, Inc. has been operating a bulk hauling facility at Charlotte, North Carolina since 1972. Until the late 1970 's, two lagoons were used to treat rinsewaters generated in the cleaning of empty tank trucks. Use of the lagoons was terminated in 1985 when a new on-site pretreatment system commenced operation. On May 30, 1990 1 Central Transport, Inc. and the State of North Carolina, Department of Environment, Health and Natural Resources, Division of Solid Waste Management, Hazardous Waste Branch entered into an Administrative Order on Consent to address certain conditions at the Charlotte site at 600 Melynda Road, in Mecklenburg County, North carol ina in a manner consistent with State and Federal hazardous waste laws and rules. By entering into this order, CTI agreed to manage surface impoundments (the waste management area) in accordance with all closure, post-closure, ground water and financial 1 OBRIEN & GERE • • July 26, 1990 assurance requirements applicable to such units under North Carolina Hazardous Waste Management Rules, and the Solid waste Management Act. This Plan has been prepared to describe the closure and post closure monitoring of two surface impoundments (Lagoons 1 and 2, Figure 3). Closure, as described in Section F-1, will consist of discharge of liquids in lagoons 1 and 2 to the Charlotte-Mecklenburg Utility District, (permit number GOOS) excavation of approximately 5200 cubic yards of sludge from Lagoons 1 and 2, on-site stabilization of the lagoon sludges, off-site disposal of the stabilized sludges as non-hazardous waste and regrading of Lagoons 1 and 2. A third pond (Figure 3) will be regraded to allow free drainage. Pond 3 appears to have been unintentionally created as a result of the construction of Lagoon 1. Pond 3 will be regraded to restore the area to its original topography . 2 O'BRIEN & GERE • • • A RCRA Part A Permit ~ !!!!!iii~ ,,,= ...

In 1972, the Charlotte terminal was connected to the CMUO Sanitary Sewer system. Following this connection, the lagoons served as a pretreatment system. In the late 1970s, a pretreatment plant was constructed at the terminal. The two lagoons served as a backup to the pretreatment system. In 1985, two aboveground rinsewater storage tanks and a new pretreatment plant were constructed. Use of the lagoons was terminated in 1985 when the new pretreatment system commenced operation. Figure 3 is a site plan which shows the location of the two on-site lagoons. Lagoon 1 was constructed with concrete walls and with native clay materials on the bottom • Rinse waters in Lagoon 1 were aerated using two floating aerators. Lagoon 2 was an existing pond that had been constructed as a farm pond prior to Central Transport•s purchase of the site, according to available background information. Pond 3 shown on Figure 3 appears to have resulted from construction of the lagoons. An intermittent stream runs through the location of Pond 3. B-lb Regional Geology The CTI site is located within the Piedmont physiographic province of North Carolina, in the Charlotte Belt. The massive crystalline and metamorphic rocks of the Piedmont are 6 O'SRIEN & GERE • • July 26, 1990 covered by a layer of unconsolidated clayey to sandy material, consisting of weathered parent rock and alluvium (Cederstrom, 1979) . The underlying Charlotte Belt has been interpreted as a tilted composite mass of intrusive igneous rock that has been eroded (Wilson, 1983). The immediate vicinity of Charlotte is underlain by a granite and diorite complex, which is interfingered with a variety of local sedimentary and metamorphic rocks (Legrand, 1952). Rocks in the Charlotte Belt range in age from Paleozoic to Precambrian. B-lc Regional Hydrogeology The shallow ground water in the Charlotte area occurs in the clayey to sandy soil as an unconsolidated water table aquifer. The unconsolidated aquifer acts as a reservoir which transmits water to the bedrock. The bedrock ground water is contained in the joints, fractures, cleavage planes, bedding planes, and solution channels in the rock (Legrand, 1952). The flow of ground water within the unconfined aquifer is dictated by topography; in other words, the surface of the water table roughly mimics the land surface. Within the bedrock aquifer, however, ground water flow is controlled by the system of joints and fractures (Legrand, 1952) . 7 C:'BRiEN & GERE • • Julv 26, 1990 The soil boring locations were selected to provide a preliminary assessment of the soil quality in the vicinity of the lagoons. The five soil borings were advanced using the hollow stem auger drilling method. The augers were advanced until auger refusal indicated that bedrock had been encountered. Split spoon samples of the unconsolidated overburden were collected continuously. The soil sampling method employed was ASTM D-1586-84/Split Barrel Sampling, using a 2-inch outside diameter split spoon sampler with a 140-pound hammer. Following the collection of each soil sample, the split spoon sampling barrel was decontaminated with soapy distilled water followed by a nitric acid rinse, a methanol rinse, and a distilled water rinse. The head space in each soil sample jar was screened in the field using a photoionization organic vapor detector (HNU Model PI-101), in order to provide a preliminary indication of the presence of volatile organic compounds within the soils. Boring logs containing the field screening results and detailed descriptions of the geologic materials encountered during the drilling of each boring are included in Appendix B. Based on the results of the head space screening and upon visual observations, soil samples were selected for analysis. Two samples were chosen per boring: the 2 to 4 foot depth 10 • • • July 26, 1990 sample and the 6 to 8 foot depth sample. The samples were from the unsaturated zone, above the water table. The soil samples were analyzed for metals, voes, base/neutral extractables, acid extractables, pesticides, and PCBs. The analytical results are summarized in Table 2; for metals, both a range and average of concentrations commonly found in soils in the USA are also included. The reference for the range and average of concentrations is the USEPA, Office of Solid Waste and Emergency Response, Hazardous Waste Land Treatment, SW-874 (April, 1983), page 273, Table 6.46. Constituents which were not detected in the samples are not included on Table 2 . Oyerview -Soil Quality A comprehensive discussion of the soil sample analytical results is presented in the report entitled "Hydrogeologic Investigation", which was submitted to the State of North Carolina on June 20, 1990. A brief summary is presented in this document. It should be noted at the outset of the discussion that the analytical results provide a generally positive assessment of site soil quality. While isolated areas of soil contamination have been detected, the contamination is relatively limited and does not appear to be 11 • • ---·---- July 26. 1990 related to the lagoons. No consistent pattern of soil contamination was evidenced by the analytical results. Summary -Soil Quality The following items represent the significant findings in the soil analysis. Arsenic was detected in the MW3 2 to 4 foot depth sample at a concentration of 1615 ppm; the common range is 1-50 ppm. The presence of arsenic can possibly be attributed to naturally occurring minerals that may be present in the soil. voes were detected in the MWl 6 to 8 foot depth sample, and the MW3 6 to B foot depth sample, but were not detected in other samples.

At each well site, a new piece of clear plastic sheeting was laid down around the well. Clean equipment was placed on the plastic sheeting. A new length of polypropylene rope was attached to the bailer. The sampler put on a new pair of rubber gloves at each new well site. The sample jars were labeled and placed in a styrofoam cooler with icepacks for shipment to the laboratory for analysis. A trip blank and field blank were included for quality control/quality assurance purposes. The trip blank consisted of two 40-ml vials filled in the laboratory with distilled, uncontaminated water. The trip blank was shipped with empty sample bottles from the lab to the site, and with full sample bottles from the site to the lab.

F-2eC5llCil Flow Direction In each of the two on-site flow regimes, potential flow direction will be perpendicular to contour lines that will be drawn to represent equal ground water elevations. The potential flow direction will be toward lower ground water elevations. The ground water elevation data will be tabulated in a manner similar to Table 7, and will be plotted in a manner similar to Figure 7. F-2e(5l1Ciil Flow rate In each of the two on-site flow regimes, the hydraulic gradient will be derived from the contour lines that will be drawn. Using the values for hydraulic gradient, ground water flow velocities will be calculated as described in the Hydrogeologic Investigation Report. 54 • I • July 27, 1990 It should be noted that, of the three variables in the velocity equation, the only one that can vary with the passage of time is the hydraulic gradient. On October 20, 1989, in-situ hydraulic conductivity tests were performed on wells MW6 through MWll to estimate the hydraulic conductivity (or permeability) of the screened aquifer material. The hydraulic conductivity was calculated by measuring the rate of recovery of the water level immediately following the development of each well. The Hvorslev method was used to calculate the hydraulic conductivities. The in-situ hydraulic conductivity tests will not be repeated each year. Similarly, while varying ground water elevations may result in varying ground water flow velocities and in varying potential flow directions, the hydraulic pathways (a joint or fracture) needed for ground water flow in a fractured bedrock aquifer will not vary with the passage of time. The 55 • • July 27, 1990 fracture trace analysis described in the Work Plan and the Supplemental Report will not be repeated each year. F-2e(5lm Statistical Determination Statistical procedures will be as discussed under F-2e(5), F-2e(5)n Results It is estimated that laboratory results will be received approximately 30 days after any given sampling round. It is estimated that up to 30 days will be required to perform the statistical analysis, once laboratory results have been received. Thus, an evaluation as to whether there has been a statistically significant increase over background values for each parameter monitored at the compliance point wells will be available 60 days after the completion of any given sampling round. F-2f Maintenance Plan Maintenance activities are not applicable to this closure scheme, as no hazardous wastes or related structures will be 56 Jµly 27. 1990 located at the facility. The area of the former surface impoundments, following removal of the solidified materials, shall be regraded, and seeded. No special maintenance activities need be designated, as there is no concern nor hazard presented by the native earthen materials remaining under the newly seeded areas. Reseeding, fertilization and mowing will be performed as part of the facility's regular landscaping care procedures. F-2g Special Waste Management Plan This section is not applicable to the CTI Charlotte terminal, as the surface impoundments were not used to contain chlorinated-dioxins, -dibenzofurans or -phenols. F-2h Land treatment The CTI facility does not operate a land treatment unit, thus this section is not applicable to this closure plan. f-2i Personnel Training Inspection and routine procedures will be carried out by qualified personnel (Environmental Director or his designee) from CTI. Ground water sampling will be performed by qualified contracted personnel. Required training for contracted 57 • July 27, 1990 personnel will depend on the activity performed. Only appropriately trained and qualified personnel will be contracted for the ground water sampling. Employees involved with post-closure activities, such as inspection and recordkeeping, will receive on-the-job training specific to their job assignment. This training will be performed by the Environmental Director, or contracted personnel familiar with this project. F-3 Notice to Local Land Authority CTI will not have hazardous waste land disposal activities at the Charlotte facility following the closure activities. Therefore, this section is not applicable. F-4 Notice in need CTI will not have hazardous waste land disposal activities at the Charlotte facility following the closure activities. Therefore, this section is not applicable. F-5 Closure Cost Estimate 40 CFR 270.14(b)(15), 10 NCAC lOF .0034 (b) (5) Table 13 itemizes the costs expected to be incurred during closure of the site. The total closure project cost is currently estimated at $2.4 million . 58 • July 27, 1990 F-6 Financial Assurance Mechanism 40 CFR 270.14lbl(15l, 10 NCAC lOF .0034{b)(5) A letter of credit will be issued by the North Carolina National Bank to CTI for 2.5 million dollars to cover both closure and post closure costs. Both the letter of credit and the standby trust agreement are being processed and will be finalized imminently. F-7 Post-closure cost Estimate A Post-Closure cost estimate for CTI' s Charlotte, NC facility is presented in Table 14. The total 3 year present worth cost for post closure monitoring is $211,024. The value presented is based on a present worth analysis of the annual costs, assuming a 10% inflation factor over the three years of the post-closure work. All on-site post-closure work will be supervised and performed by qualified CTI or contracted personnel. However, the cost estimate has been prepared assuming all activities are to be performed by contracted personnel, in accordance with 40 CFR 264.144. The Post-Closure cost estimate will be updated annually to reflect the effects of inflation. This update will be made within 60 days prior to the anniversary date of the establishment of the financial instruments used as financial 59 • July 27, 1990 assurance. This adjustment will be made using the inflation factor from the most recent Implicit Price Deflator for the Gross National Product, as published by United states Department of Commerce. The Post-Closure cost estimate will be adjusted within 30 days of a revision the Post-Closure plan, if such a revision causes an increase in the cost of Post-Closure care. The facility will maintain the latest Post-Closure cost estimate. F-8 Financial Assurance Mechanism for Closure and Post- closure Care A letter of credit for $2.5 million from North Carolina National Bank has been obtained by CTI for closure and post- closure care. A letter of credit will be issued by the North Carolina National Bank to CTI for 2.5 million dollars to cover both closure and post closure costs. Both the letter of credit and the standby trust agreement are being processed and will be finalized imminently. F-9 Liability Requirements 40 CFR 270.14(b) (17), 10 NCAC lOF .0034(b) (5) The liability requirements for sudden and nonsudden accidental occurrences do not apply to CTl's lagoons. The requirements, set forth at 40 CFR 265.147, are intended to 60 • July 27, 1990 provide coverage for bodily injury and property damage to third parties caused by sudden or nonsudden accidental occurrences arising from operations of the facility. CTI's lagoons are not, and have not been for some time, a facility in operation. In fact, they are ready to be closed imminently . 61 • REFERENCES 1.

I ,. • Appendix D Stabilization Study • • after the two days of curing. Free water was not present in any of these samples and the samples could not be compressed by applying hand pressure. Following three days of curing, samples 2-1 1 2-2 1 2-3 and 5-2 exhibited these same properties. The addition of quicklime to the sludge at all ratios given J.n Attachment 1 resulted in significant releases of heat, thereby rendering this approach unacceptable for use in the field. Samples 5-2 and 5-3 exhibited temperature rises in excess of 200 degrees Fahrenheit. A volume increase of 60 percent was also noted for sample 5-3, which would also tend to preclude the use of quicklime for the stabilization method. Unconfined compressive strength tests were conducted on samples 1-3, 2-1, 2-2, and 2-3. Samples 5-2 and 5-3 were not tested due to the significant release of heat during stabilization testing. The results of the unconfined compressed strength tests are shown on Table 2. The stress strain diagrams are also included. B. July 1990 Treatability Study Experimental Procedure The experimental procedure used in the July 1990 treatability study was similar to that used in the September 1988 treatability study. The stabilized sample was cured for 4 days before further physical (unconfined compression strength) and chemical {TCLP) analyses were performed on the sample . D-3 U'Rf·\il:r~ ,:_.. CFl·•:[ • • • Results Following a four-day curing period no free water was present in the samples. One sample was chosen for further study. The sample that was selected was that which had 50% (by weight) addition of Portland cement because its visual appearance seemed to represent the results of the September 1988 treatability study wherein the Portland cement showed a high unconfined compressive strength and a low percent volume increase. TCLP and unconfined compression strength tests were conducted on this stabilized sample. Visual observation of samples which had been stabilized with cement kiln dust and Portland cement indicate that the use of other stabilization media will yield similar TCLP and unconfined compression test results • The results of TCLP tests conducted on untreated and stabilized sludge are summarized on Table 11 of the closure plan. Nearly all TCLP parameters were below detection limits in both the "before" and "after" stabilization TCLP tests. The primary constituent detected in the untreated sample TCLP test was 2-methylphenol at a concentration of 400 microgram/ 1 i ter ( ug/ 1) . The post stabilization TCLP test demonsrated that 2-methylphenol was reduced to 15 ug/l, a 96% reduction in the leachability of 2-methylphenol. An unconfined compression strength test was performed on the stabilized sample. The results are shown on Table D-3. The peak stress of 167 psi suggests that a smaller volume of D-4 • Portland cement or cement kiln dust could be used as long as TCLP requirements are met. Conclusions The September 1988 and July 1990 treatability studies demonstrated that stabilization is a viable remedial alternative for the treatment of the sludge at CTI because it reduces the leachability potential to near detection limits and provides unconfined strengths satisfactory for acceptance at appropriately permitted landfills. Specification Section 02240 (Appendix F) sets forth criteria for acceptable processes that may be considered. D-5 • • • Appendix E .......... ---~iiii~ ~ aemEN 6 GERE • Appendix E Supplemental Work Plan • WORK PLAN SUPPLEMENTAL PHASE I HYDROGEOLOGIC INVESTIGATION CENTRAL TRANSPORT, INC. CHARLOTTE, NORTH CAROLINA INTROQUCTION O'Brien & Gere Engineers, Inc. has been retained by Weinstein & Sturges, P.A., legal counsel to central Transport, Inc. (CTI), to provide the hydrogeologic services necessary to assess whether contamination has occurred in the ground water near two lagoons located at the Charlotte, North Carolina terminal site. An initial hydrogeologic investigation has been conducted by O'Brien & Gere. The investigation was outlined in the Work Plan for the Ground water Monitoring Program, which was included as an Appendix to the draft June 1989 Lagoon Closure Plan. The results of the initial hydrogeologic investigation are included in the May 1990 Report of the Hydrogeologic Investigation. In February 1990, the state of North Carolina provided Weinstein & Sturges, CTI, and O'Brien & Gere with comments regarding the above-mentioned Work Plan. The States's comments resulted in a revised Work Plan for the Ground Water Monitoring Program. The revisions to the Work Plan are essentially clarifications of procedures; the revised Work Plan is appended to the June, 1990 report. The state's comments further resulted in this document, the Draft work Plan for the supplemental Phase I Hydrogeologic WP-1 OBRIEN S. GERE • Investigation. The purpose of this document is to outline tasks that were not included in the above-mentioned Work Plan, but that are required to fulfill the Administrative Order on Consent, dated May 30, 1990 between central Transport, Inc. and state of North Carolina, Division of Solid Waste, Hazardous Waste Section. In summary, the purpose of this Draft Work Plan is to outline a supplemental hydrogeologic investigation that will, in combination with the investigation already completed, fulfill the requirements of the Consent Agreement. Four supplemental tasks, as follows, will be completed: 1. Fracture Trace Analysis 2. Assessment of Potential for Vertical Ground Water Flow 3. Ground water Sampling and Analysis 4. Report Preparation SUPPLEMENTAL TASK 1: FRACTURE TRACE ANALYSIS As discussed in Section 3.03 of the June 1990 report, in a fractured bedrock aquifer, both a hydraulic pathway and hydraulic potential are needed for ground water flow. While ground water elevation data from the bedrock wells has been used to assess the hydraulic potential, data has not been collected regarding the hydraulic pathways. Since ground water flow in bedrock is generally controlled by fractures, a fracture trace analysis will be WP-2 [J'BRIEN & GERE • • conducted in order to provide data regarding the hydraulic pathways. While subsurface features such as fractures cannot be directly observed on photographs, surface features directly influenced by fractures, such as stream channels and geomorphic features, can be mapped. In regions like the North Carolina Piedmont, where the unconsolidated overburden consists of weathered, in-situ remnants of the competent bedrock, the fractures are typically reflected as linear areas of accelerated erosion. Erosion controls topography and surface drainage patterns because water flows through areas of least resistance. Therefore, surface features such as drainage patterns and topography typically reflect the underlying bedrock fracture patterns . The fracture trace analysis will be based upon available aerial photographs and upon the U.S. Geological Survey 7.5 Minute Quadrangle topographic map of the area. The photographs will be analyzed first; then, the topographic map will be analyzed, to confirm the patterns observed on the photographs, and to reveal any fracture traces obscured on the photographs by vegetation or cultural features. The fracture trace analysis will be verified in the field to the greatest extent practicable. In the report, the fracture trace analysis will be presented in two formats: first, a figure showing the traces WP-3 U8RIEN & GERE • overlaid on the topographic map will be provided; second, a rose diagram representing the orientation of fractures will be provided, The data provided by the fracture trace analysis will be used to either confirm or modify the generalized flow map for the bedrock aquifer included in the June 1990 report. SUPPLEMENTAL TASK 2: ASSESSMENT OF POTENTIAL FOR VERTICAL GROUND WATER FLOW In order to assess the potential for vertical ground water flow on the site, one additional bedrock monitoring well will be installed at the site. The well will be located adjacent to bedrock monitoring well MW 11, so that a well nest is formed. The additional monitoring well, to be designated MW 12, will be deeper than MW 11. MW 11 was completed at a depth of 27 feet below ground level. MW 12 will be completed at a depth which is a minimum of approximately 50 feet deeper than MW 11, in the first water bearing zone encountered at or below the minimum depth. A zone will be considered to be water bearing if it yields a minimum of approximately 1 gallon per minute. Regarding the state's requirements for three monitoring wells to be located downgradient of the waste management area, MW 11 is considered a downgradient well. The new MW 12 will be considered a downgradient well. Given the difficult drill rig access to the downgradient area (due to topography), the WP-4 0 BRIEN & GERE ·• "Standards of Construction -Wells Other Than Water Supply". A well construction permit will be obtained from the State prior to well installation. Following installation of the well, the well will be developed using compressed air or pumping methods in order to clear fine-grained sediments from the well screen. water generated from well development will be discharged to the ground at the well site. Equipment used for well installation that comes in contact with potentially contaminated material will be decontaminated with a high pressure steam clean wash. water generated from equipment decontamination will be discharged to the ground at the decontamination area. A field survey will be conducted by a local surveyor to determine the location and elevation of the well. Both the ground surface elevation and top of PVC casing elevation will be obtained for the well. The survey will be completed using an established on-site bench mark. An in-situ hydraulic conductivity test will be performed on the well to estimate the hydraulic conductivity (or permeability) of the screened aquifer material. The hydraulic conductivity will be calculated by measuring the rate of recovery of the water level immediately following the development of the well. The Hvorslev method will be used to calculate the hydraulic conductivity. WP-6 O'BRIEN & GERI:: • Static ground water elevations will be measured in all of the monitoring wells on the site, including the new MW 12, using an electric well probe. If measurements are taken in conjunction with ground water sampling, they will be taken prior to initiating ground water purging or sampling procedures in any of the wells. The static ground water elevations will be used to evaluate horizontal ground water flow direction in the study area. The comparison of static ground water elevations from MW 11 and MW 12 will allow an assessment of whether there is upward or downward vertical flow in the bedrock aquifer in the vicinity of the MW 11/MW 12 well nest. SUPPLEMENTAL TASK 3: GROUND WATER SAMPLING AND ANALYSIS Two rounds of ground water samples were collected as part of the initial hydrogeologic investigation. The sampling results are included in the June 1990 Report of the Hydrogeologic Investigation. The State's comments included changes in O'Brien & Gere•s Ground water Sampling Protocol. Specifically, changes in procedure for the filtering and acidification of metals samples were required. Futher ground water sampling is required in order to meet the metals sampling requirements, to access the ground water quality of the new MW 12, and to further assess the ground water quality of the site . WP-7 O'BRIEN & Gl::RE • One round of ground water samples will be collected from the following wells: MW 1, MW 2, MW 6, MW 7, MW 8, MW 9, MW 10, MW 11, and the new MW 12. Ground water purging or sampling procedures will not be initiated at MW 12 until a minimum of 24 hours after its development. Static ground water elevations will be measured in all of the monitoring wells on the site, using an electric well probe, prior to initiating ground water sampling or purging procedures in any of the wells. Ground water sampling procedures will be according to the Ground Water Sampling Protocol included as Appendix B. The protocol includes a sample Ground Water Sampling Field Log and a sample Chain of custody Record. A description of sampling procedures is also included here. Before a well is sampled, the ground water elevation in the well will be used to calculate the volume of water standing in the well. Three times the well volume will be removed from the well by pumping or by bailing with a clean, stainless steel bailer so that the ground water sample is representative of the water in the screened section of the aquifer. The sampler will measure the temperature, pH, specific conductance, and turbidity of the ground water sample in the field. Ground water samples will be collected with a clean, stainless steel bailer. Before each use, the bailer will be washed with soapy distilled water, followed by a nitric acid WP-8 CJ'8RIEN & GERE • • rinse, a methanol rinse, and a distilled water rinse. At each well site, a new piece of clear plastic sheeting will be laid down around the well. Clean equipment will be placed on the plastic sheeting. A new length of polypropylene rope will be attached to the bailer. The sampler will put on a new pair of rubber gloves at each new well site. The sample jars will be labeled and placed in a styrofoam cooler with icepacks for shipment to the laboratory for analysis. A trip blank and field blank will be included for quality control/quality assurance purposes. Chain-of-custody documents for each sample will be initiated at the time of sampling and will be maintained throughout the handling and submission of the samples to the laboratory. The ground water samples will be analyzed for the following inorganic compounds: 1. Aluminum 13. Magnesium 2. Antimony 14. Manganese 3. Arsenic 15. Mercury 4. Barium 16. Nickel 5. Beryllium 17. Potassium 6. Cadmium 18. Selenium 7. Calcium 19. Silver 8. Chromium 20. Sodium 9. Cobalt 21. Thallium WP-9 0 BRIEN S GERE • • 10. Copper 11. Iron 12. Lead 22. Vanadium 23, zinc 24. Cyanide The ground water samples will also be analyzed for the following EPA Priority Pollutants: Acid Extractables, Base/Neutral Extractables, Pesticides/PCBs, and Volatile Organic Compounds. In addition, the ground water samples will be analyzed for parameters listed in the North Carolina Administrative Code, Title 151 Subchapter 2L -"Classifications and Water Quality Standards Applicable to the Groundwaters of North Carolina", Section . 0202 -11 Water Quality Standards", paragraph (g), that are not included in any of the above lists or categories, with the exception of dioxin, gross alpha particle activity, radium-226 and radium-228. Based on previous chemical analyses of samples from lagoon surface waters, lagoon sludges, soil and ground water, there is no reason to suspect the presence of the last four parameters in the ground water. Dioxins are typically associated with the presence of PCBs, which have not been previously detected on the site. No known sources of radionuclides are, or have been, present on the site. A complete list of analytical parameters and methods is included in the Ground Water Sampling Protocol. rt should be noted that in addition to the unfiltered inorganics analyses required by the state, O'Brien & Gere will WP-10 O'BRIE:N & GERE • • submit a set of filtered samples to the laboratory for inorganics analyses. These samples will be filtered in the field using a peristaltic pump with an in-line 0.45 micron filter. This is reflected in the Ground Water Sampling Protocol. SUPPLEMENTAL TASK 4: REPORT PREPARATION Following completion of Tasks 1 through 3 and receipt of the analytical results, a report will be prepared. This report will be considered to be a supplement to the June 1990 Report of the Hydrogeologic Investigation. The supplemental report will summarize the field investigation procedures and observations and present the data collected in the form of drilling logs, tables, and figures. The data interpretation and site assessment will be discussed. The following specific information will be included: results of the fracture trace analysis, as discussed above; an evaluation of the horizontal and vertical directions of ground water flow; an updated ground water contour map will be included if appropriate; a flow net will be included if vertical flow potential exists; an evaluation of the ground water quality, in tabulated and/or graphic form where appropriate; data from the new well MW 12 will be included; WP-11 O'BRIEN & GERE • • • APPENDIX A TYPICAL MONITORING WELL CONSTRUCTION O'BRIEN & GERE • • APPENDIX B GROUND WATER SAMPLING PROTOCOL 0 BRIEN & GERE • 8. Pull the bailer out of the well keeping the polypropylene rope on the plastic sheet or entirely off the ground if it is too windy to place a plastic sheet. The LEXANR bailer can be used to observe the presence of any floating product layer and the physical appearance of the ground water. 9. Record the physical appearance (color, odor, turbidity, and presence of floating product) of the ground water on the Ground water Field Sampling Log. 10. If a floating product is observed, estimate its volume and note this on the Ground Water Sampling Field Log. The LEXANR bailer should be used to collect a sample of any floating product layer into 40 ml vials for product identification. After this sample is collected, or if no floating product is found, proceed to the next step. 11. Attach the polypropylene rope to a clean, stainless steel bailer, lower the bailer to the bottom of the well, and agitate the bailer up and down to resuspend any material settled in the well. 12. Initiate bailing the well from the well bottom making certain to keep the polypropylene rope on the plastic sheet. All ground water should be poured from the bailer into a graduated pail to measure the quantity of water removed from the well. 13. 14. continue bailing the well throughout the water column and from the bottom until three (3) times the volume of ground water in the well has been removed, or until the well is bailed dry. If the well is bailed dry, allow sufficient time for the well to recover before proceeding with the next step. Record this information on the Ground Water sampling Field Log. Remove the sampling bottles from their transport containers, and prepare the bottles for receiving samples.
