Westinghouse Remediation Services will conduct the Site Investigation. EARTH TECH (formerly WW Engineering & Science) will monitor and observe field activities conducted by the PRP's remediation service and determine whether these activities are being performed in accordance with the PRP's Work Plan, Quality Assurance Project Plan, Field Sampling Plan, and Health and Safety Plan (collectively referred to as Project Plans), prepared by the contractor. Site Investigation and Remedy Development oversight field activities include collecting and splitting sediment, surface water, and groundwater samples on the majority of the samples collected by the PRPs. While Westinghouse is restricting their analysis to only PCBs, EARTH TECH will collect and submit sediment, surface water, and ground water samples according to routine analytical services (RAS) protocol for organics and inorganics as well as dioxins and furans by special analytical services (SAS). The groundwater from the residential wells will be analyzed using low concentration SASs for organics, inorganics, and for dioxins and furans. The purpose of conducting oversight of sampling is to evaluate the sampling, shipping, and analytical procedures of the PRP's contractor and laboratory, as well as to analyze samples for a more complete list of possible contaminants. An overview of the site location is described in the QAPP for the Bloomington Sites Vol. I, March 1995. A more detailed description of site conditions is presented in QAPP-Volume II, Field Sampling Plan for the Lemon Lane Groundwater Monitoring investigation, March 1995. The Lemon Lane Landfill site covers approximately 10 acres and is located on the northwest side of Bloomington, Indiana in Monroe County (Figure 1-1). 1.1 SITE BACKGROUND AND HISTORY The following site history and background information is taken directly from the QAPP for the Bloomington Sites, Westinghouse Bloomington Project, March 1995. (EDITORIAL NOTE TO BBS USERS: IN THE EPA/EARTH TECH DOCUMENT, SECTIONS 1.1.1 THROUGH 1.1.9 WERE WRITTEN IN ITALICS) 1.1.1 SITE BACKGROUND The Lemon Lane Landfill is on the northwest side of Bloomington in Monroe County, Indiana. The 10-acre landfill is bounded on the east by Lemon Lane, on the south by the L&N Railroad, on the north by residential property, and on the west by undeveloped land. The Indiana State Route 37 Bypass is about 900 feet northwest of the landfill entrance. 1.1.2 WASTE DISPOSAL The Lemon Lane Landfill opened as a refuse dump in 1933. The City of Bloomington operated the landfill from 1950 to 1964 as a municipal waste landfill. It was also used as a repository for industrial debris and waste. Electrical capacitors from Westinghouse's Bloomington Plant were deposited in Lemon Lane Landfill between 1958 and 1964 by contracted local haulers. Landfill operations were typical of the period, without the controls and design features common to modern facilities. No liner or cover was used, dumping was not controlled with regard to waste content, site security, or records, and scavenging and burning were common daily practices. In cases where the disposed items, such as capacitors, were popular in salvage activities, such items would be placed at the edge of the landfill to prevent salvagers from interfering with dump operations. 1.1.3 SITE TOPOGRAPHY The Lemon Lane Landfill is situated in a surface depression interpreted to be associated with a compound sinkhole. The compound sinkhole runs northeast to southwest and extends southwest of the Lemon Lane Site beyond the L&N Railroad. The site is near topographic divides between the headwaters of Clear Creek to the southeast, Stout's Creek to the northwest, and Griff Creek to the northeast. The topography across most of the site moderately slopes to the west. The surface elevation of the landfill ranges from 850 to 890 feet above mean sea level. 1.1.4 SITE GEOLOGY The earthen cover at the site consists of fill material and native soils ranging from about 10.5 to 43 feet thick. The fill material is described as clayey, silty, sandy, and gravelly soils mixed with varying amounts of ash, cinders, glass, plastic, wood, wire, metal, asphalt, cement, paper, and brick. The soil beneath the fill consists of indigenous red clay. The earthen cover is underlain by Mississippian age bedrock units. The St. Louis Limestone of the Blue River Group underlies the overburden layer and is in turn underlain by the Salem Limestone of the Sanders Group. The St. Louis Limestone consists of layers of gray to yellow brown limestone, dolostone, and shale, with many water-bearing and dry solution features. The Salem Limestone is described as a light grayish and yellow to gray, thick, cross-bedded calcarenite, which is famous as a building stone known as the "Indiana Limestone." Bedrock at Lemon Lane is similar to that of southern Indiana and the Bloomington area and generally dips west to southwest at about 30 feet per mile. 1.1.5 HYDROGEOLOGY The groundwater flow system associated with the site consists of recharge areas, flow areas, and discharge areas. Recharge to the groundwater flow system is believed to occur primarily through sinkholes and swallow holes in the region surrounding the landfill, and to a lesser extent by seepage through the earthen cover adjacent to the landfill. On the basis of existing data for the site, the groundwater system beneath Lemon Lane Landfill appears to occur within two intervals separated by a shale unit occurring at 782 feet above mean sea level to the east and 778 feet to the west. The shallow groundwater zone occurs within bedrock between 798 and 820 feet, and the deeper zone occurs within bedrock between 760 and 770 feet. Basin studies have indicated a maximum flow depth in the Illinois Central basin between 150 and 185 feet. This is supported by monitoring well data at Lemon Lane. Packer and slug testing of the wells demonstrated that they yield very little water. Continuous water level monitoring indicated no response to storm events in the deep wells. Low sulfate concentrations also indicated that there is not a deep paretic component of flow. Groundwater within the shallow zone is believed to flow primarily through conduits. Groundwater within the deeper zone is believed to flow primarily through fractures relatively unmodified by dissolution. In 19&7, a low-flow dye tracer test was conducted, and in 1989 and 1990, high-flow dye tracer tests were conducted to determine the groundwater flow from Lemon Lane Landfill. From data gathered during low-flow conditions, groundwater flows to the southeast and eventually drains at Illinois Central Spring and then at Quarry Spring. During high-flow conditions, the primary flow network from the landfill is still Illinois Central and Quarry springs. There are indications that a minor amount of groundwater from the perimeter of the landfill flows to the northwest and discharges at the Slaughterhouse Spring, Packinghouse (PH Road Spring, and PH Culvert Spring. 1.1.6 GROUNDWATER USE Residences and businesses near and downgradient of the landfill are served by the municipal water supply. A private well user survey published in 1986 by Indiana University School of Public and Environmental Affairs provided names and addresses of private wells used for commercial or residential purposes within 5,000 feet of the landfill. The survey concluded that there were 1,050 properties and 20 private wells in use within this radius. Since 1990, all residents served by private wells near the Lemon Lane Landfill have been connected to the city water source. This was confirmed by a Westinghouse survey. 1.1.7 SURFACE WATER HYDROLOGY The site lies along the eastern margin of the Mitchell Plain region, a low plateau developed on limestones of the Mississippian Blue River and Sanders Group. The Mitchell Plain surface is characterized by relatively flat topography with moderate slopes and by karst topography. Topographic features near the landfill include sinkholes, caves, three surface streams (Clear Creek, Stout's Creek, and Griff Creek) and associated tributaries, perennial and intermittent springs, and at least one sinking stream. A sinkhole pond (Sargent's Pond) is located northwest of the site. Springs in the area include the Illinois Central, Quarry, ICG-1, ICG-2, ICG-3, PH Road, PH Culvert, and Slaughterhouse springs. 1.1.8 SITE LAND USE Within several hundred feet to the west of the Lemon Lane site is undeveloped land owned by Westinghouse. The north and east sides of the site are bordered by residential areas (about 22 houses and 6 mobile homes). A commercial area (2 or 3 businesses) lies northeast of the site along Vernal Pike, and a cemetery lies south of the site. 1.1.9 PAST DATA COLLECTION ACTIVITIES Various investigations have been undertaken to characterize Lemon Lane Landfill since the early 1980s. Investigative activities included geophysical surveys, aerial photograph analyses, monitoring well installations, groundwater elevation monitoring, groundwater sampling and analyses (including springs), surface water sampling and analyses, stream sediment sampling and analyses, air sampling, soil boring installations, hydraulic conductivity testing, and high and low flow dye tracer tests. Numerous sampling activities have characterized PCB concentrations in environmental media at the Lemon Lane Landfill. Sampling has been performed to characterize PCDDs and PCDFs in soils and to characterize volatile organic compounds (VOCs), semivolatile organic compounds (SVOCs), metals, and pesticides in surface waters. Because surface capacitors were removed, hot spots remediated, and a synthetic membrane installed, the pre-Interim Remedial Measures (IRM) surface soil, groundwater, surface water, sediment, and air monitoring data are not representative of existing site conditions. Historical data collected at the site is contained in Appendix A. 1.2 SUMMARY OF OVERSIGHT ACTIVITIES As part of remedial oversight, EARTH TECH, the U.S. EPA Oversight Contractor, will provide field oversight of "key" activities as requested by the WAM (Work Assignment Manager). EARTH TECH will monitor and observe field activities conducted by the PRP's and determine whether these activities are being performed in accordance with the Project Plans prepared by Westinghouse Remediation. EARTH TECH oversight personnel will document field activities in a daily log. EARTH TECH will prepare and submit letter reports to the WAM summarizing field activities within 30 calendar days of completion of the activity. The EARTH TECH site project manager or his designated representative will contact the WAM in the event that there are any onsite emergencies, significant delays or problems that arise during the course of the investigation, and any significant field modifications that differ from those specified in the PRP's Project Plans. Site Investigation oversight activities include collecting and splitting sediment, surface water, and groundwater samples collected by the PRPs. EARTH TECH will collect and split surface water and sediment samples from surrounding natural springs, existing monitoring wells, and residential wells. Appendix B contains summary tables which detail sample matrices, analytical parameters, Data Quality Objectives (DQOs) and frequencies of sample collection. Because of the hydrology in the area, six springs shown to be directly hydrologically connected with Lemon Lane Landfill (Figure 1-2) will be sampled by Westinghouse Remediation for PCB contamination as described in their Field Sampling Plan. EARTH TECH will collect and split samples from these six springs in the following manner. Surface water from Illinois Central and Slaughterhouse Springs will be collected and analyzed quarterly for one year for RAS Target Compound List (TCL) organics and Target Analyte List (TAL) inorganics listed on Tables 1-1 and 1-2. Dioxins and furans listed on Table 1-3 will be analyzed using a SAS on the first and third quarters only. Sediment samples will be collected from the two springs on the first and third quarter for one year and analyzed for RAS TCL organics and TAL inorganics plus dioxins and furans. Surface water and sediment will be analyzed from the remaining four springs, Quarry, ICG- 1, PH Culvert, and PH Road springs, during two sampling events for RAS TCL organics and TAL inorganics. Nine other springs (Figure 1-2) that were shown to be hydrologically connected to the Lemon Lane Landfill will be sampled by Westinghouse Remediation for PCB contamination as described in their Field Sampling Plan. These springs include: ICG-6, Bypass 37, Urban, Crestmont, Snoddy, Stony West, Stony East, WN-1, and WS-2. EARTH TECH will collect and split samples from these nine springs in the following manner. One round of surface water and sediment samples will be split and collected from each of the nine springs for RAS TCL organics and TAL inorganics. Monitoring wells to be sampled are shown on Figure 1-3. Five monitoring wells (MW-4I, MW4D, MW-6, MW-7, and MW-8D) will be sampled quarterly for one year and the groundwater will be analyzed for RAS TCL organics and TAL inorganics. Dioxins and furans will be analyzed using a SAS on the first and third quarters only. Residential wells to be sampled are shown on Figure 1-4. The specific wells have not been selected to date and will depend on site access issues. Up to twenty residential wells will be sampled quarterly for one year using a residential well SAS for the low concentration organics and inorganics listed on Tables 1-4 and 1-5. Dioxins and furans will be analyzed using a SAS on the first and third quarters only. The majority of the oversight field samples will be submitted to the Contract Laboratory program (CLP) Laboratory. The CLP supports the U.S. EPA's Superfund effort by providing a range of state of the art chemical analysis services of known quality on a high volume cost effective basis. It provides the basic requirement to provide legally defensible analytical results for use in supporting the U.S. EPA's enforcement actions. Accuracy and precision requirements for CLP protocol analyses are described in the most recent CLP Statements of Work (SOWs). A compliance quality assurance program has been incorporated into all aspects of CLP operation. The specific laboratory or laboratories which will provide the chemical analyses of the oversight samples will be assigned by the Contract Laboratory Analytical Services Support (CLASS) on a weekly basis. Groundwater samples from residential wells will either be submitted to the Region S Monitoring Quality Assurance Branch (MQAB) or be subcontracted by EARTH TECH as a SAS. Dioxins and furans will be subcontracted by EARTH TECH as a SAS. 1.3 PROJECT SCHEDULE The sampling will occur in conjunction with the PRP's sampling schedule. Although the PRP QAPP indicates that "the project schedules are described in detail in the site-specific FSP's," EARTH TECH could not locate a succinct project schedule in the Field Sampling Plan, March, 1995. EARTH TECH personnel will provide field oversight of activities detailed in this MiniQAPP. Any field oversight deviations from the Work Plan will be with the expressed and written consent of the U.S. EPA WAM. 2.0 PROJECT ORGANIZATION AND RESPONSIBILITIES The oversight sampling program for the Site Investigation and Remedy Development Activities at the Lemon Lane Landfill site will be performed by the U.S. EPA ARCS oversight contractor, EARTH TECH. The U.S. EPA WAM, Dan Hopkins, serves as the primary contact and liaison for this site. EARTH TECH will be present on-site as specified in this document. Analyses of the majority of oversight samples will be performed by a CLP laboratory. EARTH TECH will properly schedule any analytical needs with Brian Freeman of the U.S. EPA Region 5. Arrangements for these analyses are the responsibility of the Monitoring and Quality Assurance Branch (MQAB) of U.S. EPA, Region 5. MQAB will also be responsible for final data validation of CLP data including review of tentatively identified compounds (TICs). Responsibility for external performance and systems audits of the CLP laboratory rests with the quality assurance division of U.S. EPA's Environmental Monitoring and Support Laboratory (EMSL) in Las Vegas, NV. Figure 2-1 shows the essential project organization. The Region 5 MQAB will analyze the groundwater samples from the residential wells for low concentration organics and inorganics, if their capacity allows. The Region 5 MQAB Contract Analytical Support Section (CASS) will be responsible for final data validation if the MQAB is used. If the Region 5 MQAB is unable to analyze the samples, EARTH TECH will subcontract these analyses to another laboratory as a SAS. EARTH TECH will also subcontract the data validation. Samples collected for dioxins and furans will be subcontracted as a SAS by EARTH TECH. Independent data validation will also be subcontracted. 3.0 QUALITY ASSURANCE OBJECTIVES FOR ANALYTICAL DATA The overall quality assurance objective is to ensure that the oversight data are of known and acceptable quality. They must be sufficiently precise and accurate to be used in a comparison with the data generated by the PRPs. This oversight sampling program will serve as an external quality assurance measure to check the sampling and analytical procedures of the PRPs and their laboratory. In addition, EARTH TECH will be collecting samples for separate analyses that will be used to support a Risk Assessment. To achieve the overall data quality objectives, proper sample handling and analyses and data handling procedures will be followed. These procedures are described in the following sections of this Mini-QAPP. To assess whether the overall quality assurance objectives have been met, analyses of specific field quality control samples will be required. These quality control samples include field duplicates, field equipment blanks, trip blanks and matrix spike, matrix spike duplicates (MS/MSD). The preparation of each of these types of samples is described in Section 4.0. The frequency with which they will be collected are included on the tables contained in Appendix B. Field duplicate sample results will be used to assess the precision of the field sampling procedure and laboratory results. They will be used to monitor overall precision, including the reproducibility of field sampling and laboratory analytical procedures, as distinct from the precision of analyses of laboratory replicates. Field duplicate samples are collected at a frequency of one per group of 10 or fewer investigative samples per sample matrix. Field equipment blanks will monitor contamination during all phases of sample collection, handling, storage, and analysis. They are distinct from method or laboratory blanks that do not monitor contamination introduced in the field during sample collection and handling. held equipment blank samples are collected at a frequency of one per group of ten or fewer investigative samples per sample matrix. Field equipment blanks will not be collected for monitoring well samples as the wells have dedicated sampling equipment nor for residential wells and surface water samples as no field equipment will be used to collect these samples. Trip blanks will be analyzed for volatile organic compounds only. They will monitor volatile organic compound migration during container shipment and sample storage. The trip blank sample is collected at a frequency of one per shipping cooler of volatile organic analysis (VOA) samples. Matrix Spike/Matrix Spike Duplicate (MS/MSD) samples will be collected at a frequency of one per 20 or fewer investigative samples per sample matrix. For water samples, extra sample volume shall be collected for sample designated for MS/MSD analysis. Triple the normal sample volumes will be collected for VOAs, semi-VOAs, pesticide/PCBs, and dioxins and furans. Double the normal volume is needed for metals and cyanide. For sediment samples, no extra volume is required. All sediment, surface water, and groundwater samples will be sent to the MQAB, CLP, and/or SAS laboratory for analyses. RAS TCL and TAL analyses will be performed using a current statement of work (SOW) for organic and inorganic analyses. Tables 1-1 and 1-2 contain the quantitation levels for the TCL and TAL, respectively. Either the Region S MQAB or a subcontracted laboratory will analyze the samples collected from residential wells under the provisions of a SAS contained in Appendix C. Tables 1-4 and 1-5 contain the quantitation levels for low concentration organics and inorganics for residential wells, respectively. A subcontracted laboratory will provide dioxins and furans analysis using the methods specified in the SOW DFLMO1.0. The dioxins and furans SAS is included in Appendix C. The quantitation levels for dioxins and furans are listed on Table 1-3. 4.1 SAMPLING SITE SELECTION With the exception of finalizing the selection of residential well sample locations, the remainder of the co-located sample locations have been selected and approved by the WAM. 4.2 SAMPLING PROCEDURES Sampling procedures to be used by the PRP contractor are described in the Field Sampling Plan for the Lemon Lane Groundwater Monitoring Investigation, Westinghouse, March 1995. EARTH TECH, the U.S. EPA oversight contractor, will be on-site overseeing the PRP's sampling activities. At the sampling location where an oversight sample is required, EARTH TECH will hand the PRP contractor the necessary sample containers for the oversight sample. The PRP contractor will fill their sample containers and the oversight containers at the same time. If at anytime, the volume of sample is not sufficient to fill all the required sample containers, the priority of analysis is as follows: > VOAs; > PCBs; > dioxins and furans; > inorganics; > SVOCs; and > pesticides EARTH TECH will retrieve the filled oversight sample containers. Any field measurements required will be taken by the PRP contractor and recorded by EARTH TECH in a field notebook for the oversight program at the time of sampling. The bottles used for this sampling effort will be prepared using procedures specified in "Specifications and Guidance for Obtaining Contaminant-Free Sampling Containers, December 1992." Tables contained in Appendix B outline the parameters to be analyzed and the number of quality control samples to be submitted for analysis for each media Figures 1-2, 1-3 and 1-4 present the PRP's investigation sample locations. EARTH TECH's proposed co-located sample locations are also noted on the figures. Field quality control samples will consist of field duplicates, field equipment blanks, and trip blanks. One field duplicate per every ten or fewer sample matrices will be collected simultaneously with the collection of the investigative sample. The field duplicate will be analyzed for the same parameters as the investigative sample. A field equipment blank will be collected off of the sampling device used to sample the sediment sample. After decontaminating the sampling device and prior to collecting the sediment sample, deionized water will be poured over the sampling device. The water in the sampling device will then be allowed to drain into the specified containers. The field equipment blank sample will be analyzed for the same parameters as the investigative sample. Each oversight sample cooler shipped to the CLP laboratory will contain a trip blank to be analyzed for VOAs. Each trip blank will consist of two 40 ml glass vials with Teflon lined septa caps filled with organic-free deionized water. The trip blank vials should travel to and from the field without being opened. For one investigative oversight sample, three times the normal sample volume will be collected for VOAs, extractables, pesticides/ PCBs, and dioxins and furans. For aqueous samples, double the normal sample volume will be collected for inorganics. The extra volumes will be used by the laboratory for matrix spike/matrix spike duplicate analyses. The additional sample containers will be labeled with the sample number followed by MS or MSD to identify to the laboratory which sample containers should be used for the matrix spike and matrix spike duplicate analyses. Table 4-1 contains directions on the types and quantities of sample containers required for each analysis, the proper sample preservation techniques, and holding times. 4.3 SAMPLING CUSTODY CONCERNS Sample documentation, custody procedures, sample packaging, and shipment will be performed according to the U.S. EPA requirements as described in the U.S. EPA "Sampler's Guide to the Contract Laboratory Program (December 1990)" and the "User's Guide to the Contract Laboratory Program (January 1991). Each sample container will be enclosed in a clear plastic bag and placed in a cooler packed with non-combustible, absorbent packing material. Coolers must contain enough ice to maintain sample temperatures at < 4¿C. Each cooler must be sealed with custody tape in such a manner that the tape would be broken if the cooler were opened. Waterproof tape must cover the custody tape. Coolers will be shipped by overnight carrier. 5.0 SAMPLE CUSTODY 5.1 INTRODUCTION It is EARTH TECH's policy to follow the U.S. EPA Region 5 sample custody, or chain of custody protocols as described in "NEIC Policies and Procedures", EPA-330/9-78DDI-R. Revised June 1985. This custody is in three parts: Sample collection, Laboratory analysis, and Final evidence files. Final evidence files, including all originals of laboratory reports and purge files, are maintained under document controls in a secure area. A sample and/or evidence file is under your custody if they: > are in your possession; > are in your view, after being in your possession; > are in your possession and you place them in a secured location; or > are in a designated secure area. 5.2 FIELD SPECIFIC CUSTODY PROCEDURES The sample packaging and shipment procedures summarized below will ensure that the samples will arrive at the laboratory with the chain-of-custody intact. 5.2.1 FIELD PROCEDURES A. The field sampler is personally responsible for the care and custody of the samples until they are transferred or properly dispatched. As FEW people as possible should handle the samples. B. All bottles will be tagged with sample numbers and locations. The Sample Management Office (SMO) number and stickers will be affixed. C. Sample tags are to be completed for each sample using waterproof ink unless prohibited by weather conditions. For example, a logbook notation would explain that a pencil was used to fill out the sample tag because the ball-point pen would not function in freezing weather. D. EARTH TECH will review all field activities to determine whether proper custody procedures were followed during the field work and decide if additional samples are required. 5.2.2 FIELD LOGBOOKS/DOCUMENTATION Field logbooks will provide the means of recording data collecting activities performed. As such, entries will be described in as much detail as possible so that persons going to the site could reconstruct a particular situation without reliance on memory. Field logbooks will be bound, field survey books. Logbooks will be assigned to field personnel, but will be stored in the document control center when not in use. Each logbook will be identified by the project-specific document number. The title page of each logbook will contain the following: > Person to whom the logbook is assigned; > Logbook number; > Project name; > Project start date, and > End date. Entries into the logbook will contain a variety of information. At the beginning of each entry, the date, start time, weather conditions, names of all sampling team members present, level of personal protection being used, and the signature of the person making the entry will be entered. The names of visitors to the site, field sampling or investigation team personnel and the purpose of their visit will also be recorded in the field logbook. Measurements made and samples collected will be recorded. All entries will be made in ink and no erasures will be made. If an incorrect entry is made, the information will be crossed out with a single strike mark. Whenever a sample is collected, or a measurement is taken, a detailed description of the location of the station, which includes compass and distance measurements, shall be recorded. The number of the photographs taken of the station, if any, will also be noted. All equipment used to make measurements will be identified, along with the date of calibration. Samples will be collected following the sampling procedures documented in the Mini-QAPP. The equipment used to collect samples will be noted, along with the time of sampling, sample description, depth at which the sample was collected, volume collected and number of containers. Sample identification number will be assigned prior to sample collection. Field duplicate samples, which will receive an entirely separate sample identification number, will be noted under sample description. 5.2.3 TRANSFER OF CUSTODY AND SHIPMENT PROCEDURES (a) Samples are accompanied by a properly completed chain-of-custody form. The sample numbers and locations will be listed on the chain-of-custody form. When transferring the possession of samples, the individuals relinquishing and receiving will sign, date, and note the time on the record. This record documents transfer of custody of samples from the sampler to another person, to a mobile laboratory, to the permanent laboratory, or to/from a secure storage area. (b) Samples will be properly packaged for shipment and dispatched to the appropriate laboratory for analysis, with a separate signed custody record enclosed in each sample box or cooler. Shipping containers will be locked and secured with strapping tape and EPA custody seals for shipment to the laboratory. The preferred procedure includes use of a custody seal attached to the front right and back left of the cooler. The custody seals are covered with clear plastic tape. The cooler is strapped shut with strapping tape in at least two locations. (C ) Whenever samples are co-located with a source or government agency, a separate Sample Receipt is prepared for those samples and marked to indicate with whom the samples are being co-located. The person relinquishing the samples to the facility or agency should request the representative's signature acknowledging sample receipt. If the representative is unavailable or refuses to sign, this is noted in the "Received By" space. (d) All shipments will be accompanied by the Chain-of-Custody Record identifying the contents. The original record will accompany the shipment, and the pink and yellow copies will be retained by the sampler for retuming to the sampling of fice. (e) If the samples are sent by common carrier, a bill-of-lading should be used. Receipts of bills of lading will be retained as part of the permanent documentation. If sent by mail, the package will be registered with return receipt requested. Commercial carriers are not required to sign off on the custody form as long as the custody fonn is sealed inside the sample cooler and the custody seals remain intact. 5.3 LABORATORY CUSTODY PROCEDURES The chain-of-custody procedures for the Contract Laboratory Program (CLP) are described in the Statements of Works (SOWs) for TCL Organics and TAL Inorganics referenced in Section 3.0. These custody procedures along with the holding time requirements for CLP samples are described in the appropriate SOW documents. The same custody procedures applies to SASs. 5.4 FINAL EVIDENCE FILES CUSTODY PROCEDURES The final evidence files from the MQAB and Contract Laboratory Program (CLP) are maintained by Region 5 MQAB Laboratory Support Team, Data Coordinator. EARTH TECH will maintain the field oversight of the Site Investigation and Remedy Development files along with all relevant records, reports, logs, field notebooks, pictures, subcontractor reports and the Contract Analytical Services Section (CASS) of MQAB's data reviews in a secured, limited access area and under custody of EARTH TECH's Site Project Manager (SPM). 6.0 CALIBRATION PROCEDURES The CLP calibration of laboratory instruments will be consistent with the CLP Statement of Works referenced in Section 3.0. The SAS calibration of laboratory instruments will be consistent with the SAS contained in Appendix C for low concentration organics and i: lorganics and for dioxins and furans. The PRPs contractor's field personnel will perform all required field measurements on the water samples including pH, conductivity, temperature and turbidity in accordance with the Quality Assurance Project Plan for the Bloomington Sites, Westinghouse, March 1995. EARTH TECH will document the field calibration and record measurements in the field notebook. 7.0 ANALYTICAL PROCEDURES All media sampled will be submitted for CLP RAS TCL organics and TAL inorganics and as a SAS for low concentration organics and inorganics and for dioxins and furans using the SOWs specified in Section 3.0. All analytical and quality control requirements specified in the SOWs will be adhered to by either the CLP, MQAB, or subcontracted SAS laboratory. EARTH TECH is not performing any analytical procedures in the field. 8.O DATA REDUCTION, VALIDATION, AND REPORTING Data reduction will be performed by the CLP, MQAB, or SAS laboratory in accordance with the requirements of the CLP and SAS SOWs referenced in Section 3.0. Data validation will be perforrned by U.S. EPA Region 5 Central Regional Laboratory (CRL) using the Functional Guidelines for the Validation of Organic and Inorganic Data for CLP data. An independent subcontractor will validate any SAS data in accordance with the following guidelines: > data package completeness > holding times > instrument tuning > calibration > blanks > surrogate recoveries > matrix spike/ matrix spike duplicate > field duplicates > internal standard performance > compound identification > compound quantitation Analytical results will be reported in accordance with the CLP and SAS SOWs referenced in Section 3.0. 9.0 INTERNAL OUALITY CONTROL CHECK The internal quality control check of the laboratory analysis will be in accordance with the CLP and SAS SOWs referenced in Section 3.0. No field measurements will be collected by EARTH TECH personnel. All field measurements will be taken by the PRP contractor's personnel. 10.0 PERFORMANCE AND SYSTEM AUDITS Project audits can determine adherence to established and documented sample collecting, handling and documentation procedures. Audits will be performed at the discretion of the WAM and the Quality Assurance Officer (QAO). Results of the audits will be reported to the QAO and the WAM who will identify any areas in which corrective action is needed. Performance audits of the CLP laboratory are conducted as part of, and according to, the requirements of the Contract Laboratory Program. Responsibility for such audits rests with EMSL-Las Vegas. Performance audits of the SAS laboratory may be conducted at the discretion of the U.S. EPA Region MQAB and/or Central District Office (CDO). 11.0 PREVENTTVE MAINTENANCE Laboratory equipment will be maintained according to manufacturer's specificaions and in such a way that the quality control requirements of the CLP and SAS laboratories will be met for all analyses performed No field measurements will be collected by EARTH TECH personnel, hence no preventive maintenance for field instruments is required. 12.0 DATA ASSESSMENT PROCEDURES All analytical data will be evaluated for precision, accuracy, and completeness. The acceptability of the analytical precision and accuracy will be determined by comparing them to the control limits recommended in the CLP and SAS SOWs referenced in Section 3.0. data detemmined to be insufficiently precise or accurate will be subject to the corrective action prescribed by the appropriate CLP or SAS analytical method. The quality control samples used in the determination of precision and accuracy have been described in Section 9.0. Specific equations used to calculate precision, accuracy, and completeness are presented below: Precision will be expressed in terms of relative percent difference (RPD). RPD = (Concentration 1 - Concentration 2 x 100)/((Concentration 1 + Concentration 2) /2( Accuracy as determined from the analysis of an extemal reference standard will be expressed as percent recovery (%R). % R = (Measured Concentration x 100)/Actual Concentration Accuracy as determined from the analysis of a spiked sample will also be expressed as percent recovery (%R). % R = (Spiked Sample Concentration - Sample Concentration x 100)/ (Concentration of Spike Added) Completeness will describe the number of usable analytical results as a percentage of the total number of samples submitted for analysis. % Complete = (Number of usable results x 100)/ (Number of samples submitted) 13.0 CORRECTIVE ACTIONS Corrective action must be taken any time a situation develops that threatens data quality. Corrective action may be required if field or laboratory audits reveal unacceptable deviations from approved procedures. It may be required any tirne duplicate or spiked sample analyses exceed the quality control limits or when blank analyses indicate unacceptable levels of contamination. Corrective action may include resar,npling and reanalysis of a few samples or the cessation of all analyses with subsequent reanalysis of all samples upon resolution of the problem. Specific analytical corrective actions are described in the CLP and SAS SOWs referenced in Section 3.0 and will be adhered to by the laboratory. A quality control problem that cannot be solved by immediate corrective action must be thoroughly investigated to determine the extent of the problem and to ensure that all samples affected by the problem are identified and reanalyzed. 14.0 OUALITY ASSURANCE REPORTS Analytical data will be validated in accordance with the following U.S. EPA guidance documents: 1. Region 5 Standard Operating Procedure for Validation of CLP Organic Data, U.S. EPA Region 5, Central Regional Laboratory (now MQAB) August 1993. 2. Region 5 Standard Operating Procedure for Validation of CLP Inorganic Data, U.S. EPA Region 5, Central Regional Laboratory (now MQAB), September 1993. A summary quality assurance statement will accompany the analytical results. This quality assurance report will include an assessment of data quality based on the quality control data as well as an account of any significant quality assurance problems encountered and corrective actions taken. Because data validation of the CLP analyses is the responsibility of U.S. EPA Region 5 MQAB, they will issue the quality assurance assessment of the CLP analytical results to the U.S. EPA WAM and EARTH TECH. Data validation of SAS analyses will be the ultimate responsibility of EARTH TECH. A quality assessment of any SAS analytical results will be issued to the U.S. EPA WAM via a monthly report.
