IV ------- Foreword The U.S. Environmental Protection Agency (EPA) is charged by Congress with protecting the nation's natural resources. Under the mandate of national environmental laws, the Agency strives to formulate and implement actions leading to a compatible balance between human activities and the ability of natural systems to support and nurture life. To meet this mandate, the EPA's Office of Research and Development provides data and scientific support that can be used to solve environmental problems, build the scientific knowledge base needed to manage ecological resources wisely, understand how pollutants affect public health, and prevent or reduce environmental risks. The National Exposure Research Laboratory is the Agency's center for investigation of technical and management approaches for identifying and quantifying risks to human health and the environment. Goals of the Laboratory's research program are to (1) develop and evaluate methods and technologies for characterizing and monitoring air, soil, and water; (2) support regulatory and policy decisions; and (3) provide the scientific support needed to ensure effective implementation of environmental regulations and strategies. The EPA's Superfund Innovative Technology Evaluation (SITE) Program evaluates technologies designed for characterization and remediation of contaminated Superfund and Resource Conservation and Recovery Act (RCRA) sites. The SITE Program was created to provide reliable cost and performance data in order to speed the acceptance and use of innovative remediation, characterization, and monitoring technologies by the regulatory and user community. Effective monitoring and measurement technologies are needed to assess the degree of contamination at a site, provide data that can be used to determine the risk to public health or the environment, and monitor the success or failure of a remediation process. One component of the EPA SITE Program, the Monitoring and Measurement Technology Program, demonstrates and evaluates innovative technologies to meet these needs. Candidate technologies can originate within the Federal government or the private sector. Through the SITE Program, developers are given the opportunity to conduct a rigorous demonstration of their technologies under actual field conditions. By completing the demonstration and distributing the results, the agency establishes a baseline for acceptance and use of these technologies. The Monitoring and Measurement Technology Program is managed by the Office of Research and Development's Environmental Sciences Division in Las Vegas, Nevada.

The Superfund Innovative Technology Evaluation (SITE) Program was established by the EPA Office of Solid Waste and Emergency Response and the Office of Research and Development under the Superfund Amendments and Reauthorization Act of 1986. The program is designed to meet three primary objectives: (1) identify and remove obstacles to the development and commercial use of innovative technologies, (2) demonstrate promising innovative technologies and gather reliable performance and cost information to support site characterization and cleanup activities, and (3) develop procedures and policies that encourage use of innovative technologies at Superfund sites as well as other waste sites or commercial facilities. The intent of a SITE demonstration is to obtain representative, high-quality performance and cost data on innovative technologies so that potential users can assess a given technology's suitability for a specific application. This plan summarizes the demonstration activities that will be conducted during the SITE Demonstration of monitoring and measurement technologies for dioxin and dioxin-like compounds. The demonstration will be conducted in Saginaw, Michigan, from April 26 to May 5, 2004. The demonstration is being conducted under the Monitoring and Measurement Technology Program, which is administered by the Environmental Sciences Division of the EPA's National Exposure Research Laboratory in Las Vegas, Nevada. The following six technologies will be demonstrated: • AhRC PCR™ Kit, Hybrizyme Corporation • Ah-IMMUNOASSAY® Kit, Paracelsian, Inc. Coplanar PCB Immunoassay Kit, Abraxis LLC • DF-1 Dioxin/Furan Immunoassay Kit, CAPE Technologies L.L.C. CALUX® by Xenobiotic Detection Systems, Inc. • Dioxin ELISA Kit, Wako Pure Chemical Industries, Ltd. The performance and cost of each technology will be compared to those of conventional, off-site laboratory analytical methods. The performance and cost characteristics of one technology will not be compared to those of another technology. A separate innovative technology verification report (ITVR) will be prepared for each technology. The demonstration has both primary and secondary objectives. The primary objectives are critical to the technology evaluation and require use of quantitative results to draw conclusions regarding technology performance. The secondary objectives pertain to information that is useful but does not necessarily require use of quantitative results to draw conclusions regarding technology performance. The primary objectives for the demonstration of the participating technologies are as follows: P1. Determine the accuracy. P2. Determine the precision. xvii ------- P3. Determine the comparability of the technology to the reference laboratory methods. P4. Determine the method detection limit (MDL). P5. Determine the frequency of false positive and false negative results. P6. Evaluate the impact of matrix effects. P7. Estimate costs associated with the technology. The secondary objectives for the demonstration of the participating technologies are as follows: S1. Document the skills and training required to properly operate the technology. S2. Document health and safety aspects associated with operating the technology. S3. Document the portability of the technology. S4. Evaluate sample throughput. To address the demonstration objectives, both environmental and performance evaluation (PE) samples will be analyzed during the demonstration. The environmental samples will be collected from multiple sampling locations around the country so that a diverse population of environmental samples, with varying sources and contaminant concentrations, are represented. The PE samples will include certified, spiked, and blank samples that will be obtained from commercial providers. Upon completion of the demonstration, the technology and reference method results will be compared to evaluate the performance and associated cost of each technology. The ITVRs for the six technologies will be submitted to EPA for publication in December 2004. xvin ------- Chapter 1 Introduction The U.S. Environmental Protection Agency (EPA), Office of Research and Development (ORD), National Exposure Research Laboratory (NERL) has contracted with the Battelle Memorial Institute (Battelle, Columbus, Ohio) to conduct a demonstration of monitoring and measurement technologies for dioxin and dioxin-like compounds in soil and sediment. The demonstration is being conducted as part of the EPA Superfund Innovative Technology Evaluation (SITE) Monitoring and Measurement Technology (MMT) Program from April 26 to May 5, 2004, in Saginaw, Michigan. The purpose of this demonstration is to obtain reliable performance and cost data on the technologies in order to provide (1) potential users with a better understanding of the technologies' performance and operating costs under well-defined field conditions and (2) the technology developers with documented results that will help promote the acceptance and use of their technologies. This demonstration plan describes the procedures that will be used to verify the performance of each measurement technology. The plan also incorporates a site health and safety plan and the quality assurance and quality control (QA/QC) elements needed to ensure that data of sufficient quality is generated to document each technology's performance. This plan has been prepared using the NERL's "A Guidance Manual for the Preparation of Site Characterization and Monitoring Technology Demonstration Plans"0' and in accordance with the EPA National Risk Management Research Laboratory's "Quality Assurance Project Plan Requirements for Applied Research Projects."(2) This demonstration plan describes the SITE Program, the scope of the demonstration, and the definition of dioxin and dioxin-like compounds (Chapter 1); the demonstration organization and responsibilities of the participants (Chapter 2); the six technologies that will be demonstrated (Chapter 3); sample collection, sample homogenization, and sample handling procedures (Chapter 4); the demonstration site and the sampling locations (Chapter 5); the demonstration approach, including the objectives, experimental design, data analysis procedures, and the demonstration schedule (Chapter 6); the confirmatory process, including the reference methods and the reference laboratory that will be used during the demonstration (Chapter 7); the data management procedures (Chapter 8); the QA/QC procedures (Chapter 9); the health and safety plan (Chapter 10); and references (Chapter 11). 1.1 Description of the SITE Program Performance verification of innovative environmental technologies is an integral part of the regulatory and research mission of the EPA. The SITE Program was established by the EPA Office of Solid Waste and Emergency Response and ORD under the Superfund Amendments and Reauthorization Act of 1986. The overall goal of the SITE Program is to conduct performance verification studies and to promote the acceptance of innovative technologies that may be used to achieve long-term protection of human health ------- and the environment. The program is designed to meet three primary objectives: (1) identify and remove obstacles to the development and commercial use of innovative technologies, (2) demonstrate promising innovative technologies and gather reliable performance and cost information to support site characterization and cleanup activities, and (3) develop procedures and policies that encourage use of innovative technologies at Superfund sites as well as at other waste sites or commercial facilities. The intent of a SITE demonstration is to obtain representative, high-quality performance and cost data on one or more innovative technologies so that potential users can assess a given technology's suitability for a specific application. The SITE Program includes the following elements: • MMT Program—Evaluates technologies that sample, detect, monitor, or measure hazardous and toxic substances. These technologies are expected to provide better, faster, or more cost-effective methods for producing real-time data during site characterization and remediation efforts than other conventional technologies. • Remediation Technology Program—Conducts demonstrations of innovative treatment technologies to provide reliable performance, cost, and applicability data for site cleanups. • Technology Transfer Program—Provides and disseminates technical information in the form of updates, brochures, and other publications that promote the SITE Program and participating technologies. The Technology Transfer Program also supports the technologies by offering technical assistance, training, and workshops. The demonstration of monitoring and measurement technologies for dioxin and dioxin-like compounds is being conducted as part of the MMT Program, which provides developers of innovative sampling, monitoring, and measurement technologies with an opportunity to demonstrate their technology's performance under actual field conditions. These technologies may be used to sample, detect, monitor, or measure hazardous and toxic substances in water, soil, soil gas, and sediment. The technologies include chemical sensors for in situ (in place) measurements, groundwater, soil, and sediment samplers, field- portable analytical equipment, and other systems that support field sampling and analysis. The MMT Program promotes acceptance of technologies that can be used to (1) accurately assess the degree of contamination at a site, (2) provide data to evaluate potential effects on human health and the environment, (3) apply data to assist in selecting the most appropriate cleanup action, and (4) monitor the effectiveness of a remediation process. The program places a high priority on innovative technologies that provide more cost-effective, faster, or safer methods for producing real-time or near-real-time data than conventional, laboratory-based technologies. These innovative technologies are demonstrated under field conditions, and the results are compiled, evaluated, published, and disseminated by the ORD. The primary objectives of the MMT Program are as follows: • Test and verify the performance of field sampling and analytical technologies that enhance sampling, monitoring, and site characterization capabilities • Identify performance attributes of innovative technologies to address field sampling, monitoring, and characterization problems in a more cost-effective and efficient manner • Prepare fact sheets, brochures, bulletins, newsletters, and other technical publications that enhance acceptance of these technologies for routine use. ------- The MMT Program is administered by the Environmental Sciences Division of the NERL in Las Vegas, Nevada. The NERL is the EPA's center for investigation of technical and management approaches for identifying and quantifying risks to human health and the environment. The NERL's mission components include (1) developing and evaluating methods and technologies for sampling, monitoring, and characterizing water, air, soil, and sediment; (2) supporting regulatory and policy decisions; and (3) providing the technical support needed to ensure effective implementation of environmental regulations and strategies. By demonstrating selected innovative field measurement technologies for dioxin, the MMT Program is supporting the development and evaluation of methods and technologies for field measurement of dioxin and dioxin-like compounds in a variety of soil and sediment matrices. The MMT Program's technology verification process is designed to conduct demonstrations that will generate high-quality data so that potential users have reliable information regarding the technology performance and cost. Four steps are inherent in the process: (1) needs identification and technology selection, (2) demonstration planning and implementation, (3) report preparation, and (4) information distribution. The first step of the technology verification process begins with identifying technology needs of the EPA and regulated community. The EPA Regional offices, the U.S. Department of Energy, the U.S. Department of Defense, industry, and state environmental regulatory agencies are asked to identify technology needs for sampling, measurement, and monitoring of environmental media. Once a need is identified, a search is conducted to identify suitable technologies that will address the need. The technology search and identification process consists of examining industry and trade publications, attending related conferences, exploring leads from technology developers and industry experts, and reviewing responses to Commerce Business Daily announcements. Selection of technologies for field testing includes evaluation of the candidate technologies based on several criteria. A suitable technology for field testing • is designed for use in the field or in a mobile laboratory, • is applicable to a variety of environmentally contaminated sites, • has potential for solving problems that current methods cannot satisfactorily address, • has estimated costs that are lower than those of conventional methods, • is likely to achieve equivalent or better results than current methods in areas such as data quality and turnaround time, • uses techniques that are easier or safer than current methods, and • is commercially available. Once candidate technologies are identified, their developers are asked to participate in a developer conference. This conference gives the developers an opportunity to describe their technologies' performance and to learn about the MMT Program. The second step of the technology verification process is to plan and implement a demonstration that will generate representative, high-quality data to assist potential users in selecting a technology. Demonstration planning activities include a pre-demonstration sampling and analysis investigation that assesses existing conditions at the proposed demonstration site or sites. The objectives of the pre- demonstration investigation are to (1) confirm available information on applicable physical, chemical, ------- and biological characteristics of contaminated media at the sites to justify selection of site areas for the demonstration; (2) provide the technology developers with an opportunity to evaluate the areas, analyze representative samples, and identify logistical requirements; (3) assess the overall logistical requirements for conducting the demonstration; and (4) select and provide the reference laboratory involved with an opportunity to identify any matrix-specific analytical problems associated with the contaminated media and to propose appropriate solutions. Information generated through the pre-demonstration investigation is used to develop the final demonstration design and to confirm the nature and source of samples that will be used in the demonstration. Demonstration planning activities also include preparation of a demonstration plan that describes the procedures to verify the performance and cost of each technology. The demonstration plan incorporates information generated during the pre-demonstration investigation as well as input from technology developers, demonstration site representatives, and technical peer reviewers. The demonstration plan also incorporates the QA/QC elements needed to produce data of sufficient quality to document the performance and cost of each technology. During the demonstration, each technology is evaluated independently and, when possible and appropriate, is compared to a reference technology. The performance and cost of one technology are not compared to those of another technology evaluated in the demonstration. Rather, demonstration data are used to evaluate the performance, cost, advantages, limitations, and field applicability of each technology. As part of the third step of the technology verification process, EPA publishes a verification statement and a detailed evaluation of each technology in an innovative technology verification report (ITVR). To ensure its quality, the ITVR is published only after comments from the technology developer and external peer reviewers are satisfactorily addressed. All demonstration data used to evaluate each technology are summarized in a data evaluation report (DER) that constitutes a complete record of the demonstration. The DER is not published as an EPA document, but an unpublished copy may be obtained from the EPA project manager. The fourth step of the verification process is to distribute demonstration information. To benefit technology developers and potential technology users, the EPA distributes fact sheets, newsletters, brochures, bulletins and ITVRs through direct mailings, at conferences, and on the Internet. Information on the SITE Program are available on the EPA ORD web site (http://www.epa.gov/ORD/SITE). Additionally, a Visitor's Day is held in conjunction with the demonstration so that potential users can have a first-hand look at the technologies in operation. 1.2 Scope of Demonstration Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans, commonly referred to collectively as "dioxins," are of significant concern in site cleanup projects and human health assessments because they are highly toxic. Conventional analytical methods for determining dioxin concentrations are time- consuming and costly. For example, EPA standard methods require solvent extraction of the sample, processing the extract through multiple cleanup columns, and analyzing the cleaned fraction by gas chromatography (GC)/high-resolution mass spectrometry (HRMS). The use of a simple, rapid, cost- effective analytical method would allow field personnel to quickly assess the extent of dioxin contamination at a site and could be used to direct or monitor cleanup activities. More rapidly acquired data could be used to provide immediate feedback on potential health risks associated with the site and permit the development of a more focused and cost-effective sampling strategy. More affordable and ------- quicker analytical techniques will not replace HRMS, but will complement an enhanced sampling design. However, before adopting an innovative alternative to traditional laboratory-based methods, an assessment of how commercially available technologies compare to conventional laboratory-based analytical methods using certified, spiked, and environmental samples is warranted. The purpose of the demonstration is to evaluate measurement technologies for dioxin and dioxin-like compounds in soil and sediment in order to provide (1) potential users with a better understanding of each technology's performance and cost under well-defined field conditions and (2) developers with documented results that will assist them in promoting acceptance and use of their technologies. To meet these demonstration objectives, samples will be collected from a variety of dioxin-contaminated soil and sediment sampling locations around the country. Samples will be identified and supplied through several EPA Regional offices. The samples will be homogenized and characterized prior to use in the demonstration so that a variety of environmentally derived dioxin-contaminated samples with concentrations over a large dynamic range (< 50 to > 10,000 picogram/gram [pg/g]) can be analyzed. Six measurement technologies for dioxin and dioxin-like compounds will participate in a demonstration at a field site in Saginaw, Michigan, in April 2004. The technologies will be operated by the developers in mobile laboratories or construction trailers equipped with fume hoods at the site. Draft ITVRs are planned to be available for developer review in September 2004, for peer review in October 2004, and final ITVRs will be submitted to the EPA for publication in December 2004. 1.3 Definition of Dioxin and Dioxin-Like Compounds and Toxicity Equivalents Dioxins and furans are halogenated polynuclear aromatic hydrocarbons that are considered toxic. Dioxins and furans are similar in structure as shown in Figure 1-1 and have similar chemical and physical properties. Chlorinated dioxins and furans are technically referred to as polychlorinated dibenzo-/?- dioxins (PCDD) and polychlorinated dibenzofurans (PCDF). For the purposes of this document, they will be referred to simply as "dioxins," "PCDD/F," or "D/F." Dioxins and furans are not intentionally produced in most chemical processes. However, they can be synthesized directly and are commonly generated as by-products of various combustion and chemical processes. They are colorless crystals or solids with high melting points, very low water solubility, high fat solubility, and low volatility. Dioxins and furans are extremely stable under most environmental conditions, making them persistent once released in the environment. Because they are fat soluble, they also tend to bioaccumulate. There are 75 individual chlorinated dioxins and 135 individual chlorinated furans. Each individual dioxin and furan is referred to as a congener. The properties of each congener vary according to the number of chlorine atoms present and the position where the chlorines are attached. The congeners with chlorines attached at a minimum in the 2, 3, 7, and 8 positions are considered most harmful. A total of seven dioxin and 10 furan congeners contain chlorines in the 2, 3, 7, 8 positions and, of these, 2,3,7,8-tetrachlorodi- benzo-/?-dioxin (2,3,7,8-TCDD) is the most toxic and serves as the marker compound for this class. For risk assessment purposes, estimates of the toxicity of samples that contain a mixture of dioxin and furan congeners are often expressed as toxicity equivalents (TEQ). TEQ is calculated by multiplying the concentration of each congener with a toxicity equivalency factor (TEF), according to the equation: TEQ = Cc * TEF where Cc is the concentration of the congener. The TEF (see Table 1-1) provides an equivalency factor for each congener's toxicity relative to the toxicity of 2,3,7,8-TCDD. In the 1990s, the most widely ------- accepted system of TEQs, known as the International Toxicity Equivalency Factor (I-TEF) system, was proposed by the North Atlantic Treaty Organization Committee on Challenges to Modern Society.(3) In 1997, a World Health Organization (WHO) Expert Group reassessed TEFs using a tiered approach, in which the results of animal toxicity studies, especially those involving chronic or sub-chronic exposure, were given more weight than the results of in vitro or biochemical studies.(4) In addition to re-evaluating the TEFs for humans, the group also determined separate TEFs for birds and fish. The WHO TEFs presented in Table 1-1 were determined for mammalian species that are applicable for human risk assessment purposes. The total TEQ from dioxin and furans (Total TEQD/F) in a sample is calculated by adding up all of the TEQ values from the individual dioxin and furan congeners. 2,3,7,8-TctrachlorodRwnzo-fMiioxln ct 2^,?,V-T«trachlorodibtticafuran ci 3,3>,4,4',«,y-H«xachloroblph«ny1 The close toxicological similarity of certain coplanar and mono-ortho substituted polychlorinated biphenyls (PCBs, see Figure 1-1) to dioxins has led to the extension of the TEF system to these "dioxin-like" PCBs. The dioxin-like PCBs, commonly referred to as, "WHO PCBs", that exhibit toxicity are coplanar or mono-ortho substituted and have structural and conformational similarities to dioxin compounds. Currently only 12 of the total 209 PCB congeners are FiSure 1'1' structure of representative dioxin, thought to have dioxin-like toxicity; these are PCBs with furan' and PCB< four or more chlorines with just one or no substitution in the ortho position, and which assume a flat configuration with rings in the same plane. These 12 PCBs have been assigned TEF values and are routinely included in the calculation of TEQs in toxicity assessments. The total TEQ contribution from PCBs (referred to as total TEQPCB) is calculated by summing up the individual PCB TEQ values. The total TEQ in a sample is the sum of the total TEQD/F and total TEQPCB values. TEQ concentrations for soils and sediments are typically reported in picogram per gram (pg/g) which is equivalent to parts per trillion. Concentrations of dioxins, furans, and PCBs represented as total TEQ concentration provide a quantitative estimate of toxicity for all congeners expressed as if the mixture were a TEQ mass of 2,3,7,8- TCDD only. While the TEQ concept provides a way to estimate potential health or ecological effects, the limitations of this approach should be understood. The WHO Group noted that the TEF indicates an order of magnitude estimate of the toxicity of a compound relative to 2,3,7,8-TCDD.(4) The WHO Group reported that the accuracy of the TEF factors could be affected by differences in species, in the functional responses elicited by the compounds, and in additive and non-additive effects when the congeners are present in complex mixtures. The WHO Group concluded, however, that it is unlikely that a significant error would be observed due to these differences. The larger impact to the TEF concept is the presence of aryl hydrocarbon (Ah) receptor binding compounds, such as polycyclic aromatic hydrocarbons (including naphthalenes, anthracenes, and fluorenes) and brominated and chloro/bromo-substituted analogues of PCDD/Fs, that have not been assigned TEF values, but which may contribute to the total TEQ. This potentially can result in an underestimation of TEQs in environmental samples using the TEF approach.(4) This demonstration was designed with the limitation of the TEQ concept in mind. The samples chosen contain a variety of combinations of dioxins, furans, and PCBs and at a wide range of concentration levels. Some samples are high in analytes with better understood TEFs, some are high in analytes with ------- TEFs that have more uncertainty. Some are high in other Ah receptor binding compounds such as polycyclic aromatic hydrocarbons (PAHs), while others are free of these possible TEQ contributing compounds. (Complete descriptions of the samples analyzed in this demonstration are in Chapter 5.) The purpose is to evaluate each of the technologies directly to the TEQDF and TEQPCB and assess how other factors which may contribute to a sample TEQ affect the technology's determination of TEQDF and TEQPCB. Each technology will be evaluated independently, and the statistical tests used will be described in that technology's ITVR. Table 1-1.

The U.S. EPA has compiled a database of sources of dioxin-like compounds in the United States.(5) In this database, releases in air are by far the greatest contributors of dioxins and furans to the environment. Air releases come from municipal solid waste incinerators, backyard trash burning, medical waste incineration, secondary copper smelting, and cement kilns among others. Releases to land come from land application of sewage sludge and certain pesticides contaminated with dioxins and furans. Releases in water come largely from bleached pulp and paper mill processes. In addition, certain chemical products such as pentachlorophenol and various pesticides are contaminated with dioxin-like compounds as by-products or impurities. 1.5 Traditional Methods for Measurement of Dioxin and Dioxin-Like Compounds in Soil and Sediment Traditional methods for analysis of dioxin and dioxin-like compounds involve extensive sample preparation and analysis using expensive instrumentation resulting in very accurate and high-quality, but costly, information. The ability to use traditional methods for high-volume sampling programs or screening of a contaminated site often is limited by budgetary constraints. The cost of these analyses can range from approximately $500 to $1,100 per sample per method, depending on the method selected, the level of QA/QC incorporated into the analyses, and reporting requirements. 7.5.7 High-Resolution Mass Spectrometry EPA Method 1613, Revision B(6) and SW846 Method 8290 are both appropriate for low and trace-level analysis of dioxins and furans in a variety of matrices. They involve matrix-specific extraction, analyte- specific cleanup, and high-resolution capillary gas chromatography (HRGC)/HRMS analysis. The main differences between the two methods are that EPA Method 1613 has an expanded calibration range and requires use of additional 13C12-labeled internal standards resulting in more accurate identifications and quantitations. The calibration ranges for the HRMS methods based on atypical 10-gram (g) sample and 20-microliter (\\L) final sample volume are presented in Table 1-2. Table 1-2. Calibration Range of HRMS Dioxin/Furan Method Compound Tetra Compounds Penta-Hepta Compounds Octa Compounds EPA Method 1613, Revision B 1 - 400 pg/g 5 - 2,000 pg/g 10 -4,000 pg/g SW846 Method 8290 2 - 400 pg/g 5 - 1,000 pg/g 10 -2,000 pg/g 7.5.2 Low-Resolution Mass Spectrometry SW846 Method 8280 is appropriate for determining dioxins and furans in samples with relatively high concentrations such as still bottoms, fuel oils, sludges, fly ash, and contaminated soils and waters. This method involves matrix specific extraction, analyte-specific cleanup, and HRGC/low-resolution mass ------- spectrometry (LRMS) analysis. The calibration ranges in Table 1-3 are based on atypical 10-g sample size and 100-(iL final volume. Table 1-3. Calibration Range of LRMS Dioxin/Furan Method Compound SW846 Method 8280 Tetra-Penta Compounds 1,000 - 20,000 pg/g Hexa-Hepta Compounds 2,500 - 50,000 pg/g Octa Compounds 5,000 - 100,000 pg/g 1.5.3 PCBMethods There are more options for analysis of dioxin-like compounds such as PCBs. EPA Method 1668, Revision A(7) is for low- and trace-level analysis of PCBs. It involves matrix-specific extraction, analyte- specific cleanup, and HRGC/HRMS analysis. This method provides very accurate determination of the WHO-designated dioxin-like PCBs and can be used to determine all 209 PCB congeners. Not all PCBs are determined individually with this method because some are determined as sets of co-eluting congeners. The calibration range for PCBs based on a typical 10-g sample and 50-(iL final sample volume is 1 to 10,000 pg/g. PCBs also can be determined as specific congeners by GC/LRMS or as Aroclors1 by GC/electron capture detection. 1.5.4 Summary ofAnalytical Methods for Dioxins and Dioxin-like Compounds The analytical methods described in this section were all considered for use in this demonstration. Based on the data needs of this demonstration, EPA Method 1613B was selected as the reference method for dioxins and furans, and EPA Method 1668A was selected as the reference method for the WHO PCBs. Total TEQD/F concentrations will be generated by Method 1613B and total TEQPCB concentrations will be generated by Method 1668A. These data will be summed to derive a total TEQ value for each sample. Prior to the start of the demonstration, characterization analysis by Method 1613B and LRMS modified Method 1668A will be used to determine which samples will be included in the study design. Additional discussion of the analytical methods will be presented in subsequent sections of this demonstration plan. 1 Monsanto Corporation marketed products that were mixtures of 20 to 60 PCB congeners under the trade name Aroclor. Aroclor mixtures are identified by a number (e.g., Aroclor 1260) that represents the mixture's chlorine composition as a percentage (e.g., 60%). ------- Chapter 2 Demonstration Organization and Responsibilities This chapter identifies key project personnel and summarizes their responsibilities in planning and executing the demonstration.

This information was provided by the developers with only editorial changes made by Battelle to ensure consistency and the needs of this document. 3.1 CAPE Technologies DF1 Dioxin/Furan Immunoassay Kit The DF1 Dioxin/Furan Immunoassay Kit from CAPE Technologies is an enzyme immunoassay (EIA) test kit containing a polyclonal antibody specific for PCDD/Fs. Both semiquantitative screening and quantitative analysis are possible with the DPI Dioxin/Furan Immunoassay Kit. Samples can be prepared for analysis by EIA using a variety of methods. Extracts of soil, sediment, food, water, fly ash, stack gas, tissue, or other samples that have been prepared by conventional extraction methods can be exchanged to a water-miscible solvent system for analysis using the CAPE immunoassay kit. The technology description, operating procedure, and advantages and limitations presented below are based on information provided by CAPE Technologies L.L.C. 3.1.1 Technology Description Figure 3-1. CAPE Technologies DF1 Dioxin/Furan Immunoassay Kit. The DF1 Dioxin/Furan Immunoassay Kit (Figure 3-1) is designed to analyze samples according to their TEQ concentrations by responding to the toxic PCDD/F congeners in approximate correlation with their TEFs. The test is capable of multiple congener recognition and preferentially targets congeners with high TEF values, i.e., those with the highest toxicity relative to 2,3,7,8-TCDD. The specificity of the test is predominantly for PCDD/Fs that contain 3 to 6 chlorines, with a strong preference for the 2,3,7,8 chlorinated congeners. This specificity roughly parallels the TEF values of the individual PCDD/F congeners. PCDD/Fs are typically extracted with organic solvents that are incompatible with EIA; therefore, a solvent exchange is required. PCDD/Fs have very low volatility and are retained during this solvent exchange in a small volume of a keeper solution (Triton X-100 detergent in tetraethylene glycol [TEG]) after evaporation of the original solvent. Methanol is added to dilute this solution, and the methanol-TEG-Triton mixture is added directly to the EIA tubes. The solubility of PCDD/Fs in methanol is augmented significantly by adding TEG and Triton X-100. 16 ------- During the first EIA incubation, PCDD/Fs are specifically bound by the anti-dioxin antibodies, which have been immobilized on the EIA tube surface. After washing away the unbound material, the bound PCDD/Fs remain, and a competitor-horseradish peroxidase (HRP) conjugate is added. Bound PCDD/Fs occupy the dioxin binding sites of the antibodies in proportion to the PCDD/F content of the sample and prevent binding of the competitor-HRP conjugate. After a short incubation, unbound conjugate is removed, and the test tubes are washed thoroughly. The amount of conjugate bound by the anti-dioxin antibody is inversely related to the amount of PCDD/Fs originally present in the sample. Finally, a solution of chromogenic FIRP substrate and hydrogen peroxide is added to the test tubes. Color development is directly proportional to enzyme concentration and inversely related to the PCDD/F concentration in the original sample. The test tubes are analyzed using a tube reader or spectrophotometer to measure the optical density (OD). The OD values of unknown samples are compared to the OD values of standards to determine the level of PCDD/Fs in the samples. The final measured EIA response is the sum of the individual congener responses, which correlates with TEQ because the immunoassay cross-reaction profile for PCDD/Fs correlates with TEF values. Accuracy among samples may vary solely because of the variability of congener composition. To maximize accuracy, the variability of congener composition in the target sample population should be known. The best performance is achieved when all samples are from a single group that shares as many properties as possible (common source of contamination, similar congener composition, similar sample matrix, etc.). The limit of detection for the DF1 Dioxin/Furan Immunoassay Kit claimed by CAPE Technologies is 4 pg of dioxin, which is sufficient for analysis at 500 parts per trillion (pg/g) using extract equivalent to 20 milligrams of sample. Sensitivity can be increased by adding more sample extract to the cleanup procedure and subsequently to the EIA. For example, by loading the EIA tube with the equivalent of 1 g of prepared sample, analysis can be performed at approximately 10 pg/g. When using increased sample loads, the manufacturer's recommendations for extract cleanup must be followed closely. Results must be related to the original sample concentration by back calculation using the proper dilution and volume factors. Matrix detection limits will vary according to matrix, sample size, and dilution factor. Up to 40 samples a day can be analyzed using the procedure described below. DF1 immunoassay kit starter packages include the following: • DF1-ST-A, a small starter package containing two DF1-12 kits (40 antibody-coated tubes and matching liquid reagents), one Grip-Rack, and one set of dioxin standards, plus two check samples of dioxin in toluene made by Wellington Labs. DF1-ST-B, a large starter package containing one DF1-60 kit (100 antibody-coated tubes and matching liquid reagents), one Grip-Rack, and one set of dioxin standards, plus two check samples of dioxin in toluene made by Wellington Labs. After the purchase of one starter package, subsequent purchases are either the DF1-12 orthe DF1-60 (described below). These kits do not include dioxin standards and check samples, which must be ordered separately. The DF1-12 kit for screening analysis of 12 samples includes 20 antibody-coated tubes and matching liquid reagents. The DF1-60 kit for screening analysis of 60 samples includes 100 antibody- coated tubes and matching liquid reagents. Figure 3-2 is a matrix describing the use of the DF-1 immunoassay kit. 17 ------- ANALYTICAL OPTIONS MATRIX CAPE Technologies Analytical Options cost turnaround time method specific training experience and expertise shipping of kits to customer shipping of samples to CAPE Technologies Option 1- customer performs extraction, cleanup, and analysis lowest, in the $70-90 per sample range for immunoassay and sample prep kits; final number depends on overhead and amount of QA performed fastest; on-site use is possible; same or next day results, totally dependent on customer training by PowerPoint file or in person; kit starter package for training and proficiency demo chemist preferred, some analytical experience essential, Immunoassay experience helpful immunoassay and sample prep kits ship by commercial courier In days none required Option 2- customer performs extraction, CAPE Technologies performs cleanup and analysis higher than option 1. typically in the $125-250 per sample range, but quoted on an individual job basis customer extraction plus shipping plus CAPE turnaround (standard = 10 business days, rush - 5 days, priority = 2 days from receipt of sain pies) none, but need to follow extraction Instructions little required extraction kits ship by commercial courier in days organic solvent extracts reduced to small volume solid keeper can travel by commercial courier with no restrictions Option 3- CAPE Technologies performs extraction, cleanup and analysis higher than option 2, typically In the $150-300 per sample range, but quoted on an individual job basis shipping plus CAPE turnaround (standard - 10 business days, rush = 5 days, priority = 2 days from receipt of samples) none required none required none required possible import restrictions Figure 3-2. DF1 immunoassay kit analytical options. Various options exist for using the DPI Immunoassay Kit, including having samples analyzed by the customer or by CAPE Technologies. It should be noted that the customer should have technical experience with immunoassay techniques and must perform this analysis in an analytical laboratory or some other location that can provide the necessary equipment and infrastructure (i.e., fume hood, vortex mixer, sample evaporation system, etc.). 3.1.2 Operating Procedure To ensure accurate and reliable results, every effort should be made to perform the dioxin/furan immuno- assay at temperatures between 20°C (68°F) and 25°C (77°F). The following is one option for sample preparation and was designed for same-day analysis at 500 pg/g, using a one-step cleanup. Other sample preparation options are available for lower concentrations. All sample extraction and extract cleanup components are in a kit form and are disposable. 1. Sodium sulfate is added to a soil sample and mixed. Dimethylformamide (DMF) is added to the soil sample, and the soil is extracted by shaking for two hours. The supernatant DMF extract is removed. DMF extracts are stable from weeks to months at room temperature. 2. Interferences are removed by chemical oxidation. Hexane is added to an aliquot of the DMF extract, then treated with 15% SO3 in concentrated H2SO4 (fuming sulfuric acid). The supernatant hexane is removed and exchanged to a water-miscible organic solvent solution. This hexane-based fuming sulfuric acid cleanup is sufficient for most samples; but, in certain circumstances, an additional cleanup step may be required. This is the case for samples that contain large amounts of non-volatile 18 ------- aliphatic oils. When the DMF extracts of such soils are cleaned using fuming sulfuric acid, the oil is not oxidized; it remains after evaporation of the hexane, causing a biphasic system when introduced to the EIA first incubation. Such EIA samples appear opalescent or milky, and their results are invalid because the biphasic system prevents capture of analyte by the antibody. For these samples, a new aliquot of DMF extract is cleaned by carbon adsorption. In this case, the final solvent in the cleanup procedure is toluene rather than hexane. 3. The cleaned sample in hexane or toluene is exchanged to a water-miscible organic solvent solution for EIA analysis. PCDD/Fs have very low volatility and are retained during this solvent exchange in Triton X-100 detergent in TEG after evaporation of the original solvent. Methanol is added to dilute this solution, and the methanol-TEG-Triton mixture is added directly to the EIA tubes. 4. An accurately measured volume of negative control, standard, or prepared sample is mixed with an aqueous sample diluent in test tubes with anti-dioxin antibody immobilized on the surface. The mixture is then incubated. 5. After incubation, antibody tubes are washed, and 0.5 mL of HRP competitor conjugate is added to each tube using a repeater pipettor. Bound PCDD/Fs occupy the dioxin binding sites of the antibodies in proportion to the PCDD/F content of the sample and prevent binding of the competitor-HRP conjugate. After a short incubation, unbound conjugate is removed, and the test tubes are washed thoroughly. 6. A solution of chromogenic HRP substrate and hydrogen peroxide is added to the test tubes. Color development is directly proportional to enzyme concentration and inversely related to the PCDD/F concentration in the original sample. Stop solution is added to each tube using a repeater pipettor to fix the amount of color development. 7. The test tubes are analyzed using a tube reader or spectrophotometer to measure the OD at 450 nano- meters. The test is interpreted by measuring the signal produced by a sample and determining the concentration from a dose-response curve constructed from standards tested at the same time. 3.1.3 Advantages and Limitations Extraction and cleanup using the DPI Dioxin/Furan Immunoassay Kit is faster and simpler than for GC/mass spectrometry (MS). Confirmation of selected positive samples and a portion of the negative samples by GC/MS analysis is strongly recommended. Quantitative interpretation of data is possible in certain situations. The low pg sensitivity of the DF1 Dioxin/Furan Immunoassay Kit is competitive with HRMS. This sensitivity allows for greater flexibility in designing immunoassay protocols and gives excellent tolerance of matrix interferences. The dioxin/furan congener recognition profile correlates to the TEFs of the individual PCDD/F congeners. Because of this specificity, the DPI Dioxin/Furan Immunoassay Kit has a proven correlation to TEQ. The distribution of PCDD/Fs in soil and sediment samples can be extremely heterogeneous. Adequate sample number, distribution, and homogeneity are the responsibility of the analyst. 19 ------- Samples that appear heterogeneous during the first incubation are invalid due to phase separation. Adequate sample cleanup must be assured by the analyst. 3.2 Hybrizyme Corporation AhRC PCR™ Kit The AhRC PCR™ assay couples the aryl hydrocarbon receptor (AhR) with polymerase chain reaction (PCR) technology to produce a method for analyzing dioxins and related compounds in environmental or food samples. The AhRC PCR kit can be shipped worldwide and yields results within hours. It is ideally suited for stationary or mobile laboratories. The technology description, operating procedure, and advantages and limitations below are based on information provided by Hybrizyme Corporation. The information was edited by Battelle to ensure consistency and to meet the needs of the demonstration plan. 3.2.1 Technology Description This procedure uses Hybrizyme's AhRC PCR™ kit (Figure 3-3) to detect molecules in a test sample that bind to the AhR. The AhR mediates most, if not all, of the harmful effects associated with exposure to 2,3,7,8-substituted D/F. How tightly or loosely these compounds bind to the AhR is one of the determining factors of their toxicity. The AhR also binds certain co-planar PCBs and carcinogenic PAHs, such as benzo-[a]-pyrene. Sample cleanup procedures can be employed so that all or a subset of these AhR-reactive compounds are detected by the assay. The Hybrizyme technology, with appropriate sample processing, provides a quantitative analysis of dioxins. The AhRC PCR™ kit has recently been validated and approved for use in Japan for that purpose. Correlation data from these studies with HRGC-HRMS can be found on the Hybrizyme Web site (www.hybrizyme.com). The method for quantitative determination of dioxins may not be optimal for field use, since it requires specialized training and sample processing equipment to perform. In the SITE program, Hybrizyme will use the AhRC PCR™ kit as it would be used by a field, mobile, or fixed-based laboratory to rapidly analyze samples for relative concentrations of AhR-reactive compounds. This method is inexpensive, easy to learn and uses disposable labware and relatively small quantities of solvent. Figure 3-3. Hybrizyme's AhRC-PCR Test Kit. The AhRC PCR™ kit permits the determination of compounds demonstrating measurable binding affinity with the AhR in a manner that is largely unaffected by the chemical mixture in which they reside. By virtue of the sensitivity of the assay, many of these compounds can be directly measured in simple crude extracts. The Hybrizyme method will provide a measure of the additive contributions in a single measurement of any, or all, AhR-reactive compounds present in a sample extract. The ease of use, speed of analysis, and cost of the Hybrizyme method allows it to be effectively used as a site-mapping tool, establishing a concentration gradient for AhR-reactive compounds across a large surface area. When employed in this manner, its operation resembles an uncalibrated thermometer. It has all the characteristics of a more conventional calibrated thermometer in that it is capable of providing reproducible responses for a given temperature being measured at different times, determining 20 ------- temperature gradients, and comparing one temperature to another on a relative basis. In this example the units of the thermometer are arbitrarily defined. Once a concentration grid has been established, samples already collected from predetermined "hot spots" can be analyzed by conventional HRGC-HGMS, or more sophisticated sample processing can be employed to obtain quantitative results from the AhRC PCR assay. When the Hybrizyme method is used as a screening tool, the fundamental procedures for sample preparation are simple and use relatively unsophisticated instrumentation. The results are both reproducible and reliable within the constraints of the sample processing method used to generate the reported value. The Hybrizyme method can be performed on as many as three sets of 20 samples each per day by a team of two technicians. Using this technology, the boundaries of a contaminated site can be more rapidly established. Once the initial measurements are completed, remediation efforts can begin without the need to await final data as generated by HRGC-HRMS, saving both time and money. By eliminating the need to use such sophisticated techniques on all of the collected samples, many of which typically contain low to non-detectable levels, the production of useful data is expedited in all portions of a given study. The equipment necessary to implement the Hybrizyme method can be purchased for under $45,000 U.S. A single AhR PCR™ kit is capable of producing 96 measurements; however, a portion of these assays must be dedicated to calibration and QA/QC procedures. The cost of the kit is $2,400 U.S. When used optimally, the cost of consumables per sample including the Hybrizyme kit, sample processing materials, and reagents would be under $35 per sample. The Hybrizyme method is useful in pre-screening samples in the typical laboratory performing HRGC- HRMS analyses on relatively large sample sets. Experienced laboratory personnel could eliminate all samples having low to negligible contamination using the AhRC PCR kit. Simultaneously, this data would permit organizing the remainder of the samples from the lowest to highest concentration of AhR- binding compounds. As such, the laboratory will not spend inordinate amounts of time examining "non- detects" nor will it accidentally cross-contaminate its laboratory equipment by unknowingly processing samples containing elevated levels of the expected analytes. 3.2.2 Operating Procedure 1. Reconstitute PCR wash solution to 1 X with distilled or deionized water for use with an automated plate washer. Prime the plate washer with PCR wash solution. 2. Prepare standards and unknowns in methanol. 3. Prepare the 1 X capture reagent by diluting 40 |iL of stock reagent into 600 |iL of assay buffer for each strip used. Place desired number of strips in the strip frame and reseal the remainder in the foil pouch. Wash the strips using the "3XWASH" program of the plate washer. Using the multichannel pipetter, dispense 50 |iL to each well in the strip. Shake 60 to 90 minutes. 4. Thaw the activation solution and mix gently during the process. Do not allow the activation solution to remain at room temperature for more than 20 minutes prior to use. For best results, mix the activation solution vials together prior to dispensing when performing multiple strips. 5. Dispense 50 |iL of the assay buffer into each glass vial by using a multichannel pipette. The assay buffer should be at room temperature prior to use. Add 5 |iL of standard or sample. The use of a 21 ------- pipetter (i.e., P-10 Pipetman) with a filter tip is preferred. After adding sample to the entire row, tap gently to mix. Repeat the process for each row of glass vials. 6. Add 50 |iL of activation solution to each glass vial using a multichannel pipette. Shake for 1 hour at room temperature. 7. Wash the strips using the "3XWASH" program of the plate washer. Using a multichannel pipetter, transfer 30 |iL of each reaction to each well. Shake 30 minutes. 8. Wash the strips using the "PCRWash" program of the plate washer. This series of soaks and washes takes about 15 minutes. Thaw the primer/probe solution at this time. 9. Add 100 |iL of primer/probe solution, 400 |iL of water, and 500 |iL of 2 X Universal Master Mix to make each 1,000 |iL of 1 X Master Mix. Dispense 40 |iL into each well. 10. Seal the wells with adhesive tape and cover with two compression pads. Insert the strips into a thermocycler and run the "PCR" template. 11. Analyze the data. 3.2.3 Advantages and Limitations The advantages of the AhRC PCR™ assay result, in part, from the high degree of specificity that is required for the activated receptor to bind the DNA-probe, and the unmatched sensitivity of PCR. The AhRC PCR™ assay couples the AhR with Nobel Prize-winning PCR technology to produce an easy to use, sensitive method for dioxin analysis. The AhRC PCR™ Kit can be shipped worldwide, yielding results from sample extracts within hours. It is ideally suited for stationary or mobile laboratories. The AhRC PCR™ assay takes place in disposable microwells or specialized PCR tubes, and the final product is measured by a real-time thermocycler. The Figure 3-4a. ABI Prism 7000. thermocycler never comes in contact with the sample or the assay reagents. The assay system is simple to use, requiring only limited training and technical experience. The AhRC PCR™ assay was developed for real-time PCR systems such as the ABI PRISM 7000 (Figure 3-4a), which can generate up to 96 results per run, or the Cepheid Smart Cycler (Figure 3-4b), designed to be totally transportable. Figure 3-4b. Cepheid Smart Cycler. 22 ------- 3.3 Paracelsian, Inc., Ah-IMMUNOASSAY® The Ah-IMMUNOASSAY® (Figure 3-5) is an enzyme-linked immunosorbent assay (ELISA) invented at Paracelsian, Inc. (patents pending and allowed). It is designed to screen for dioxin-like toxicity in environmental and tissue samples. The technology description, operating procedure, and advantages and limitations below are based on information provided by Paracelsian, Inc. and only editorial changes were made by Battelle to ensure document consistency and meet the needs of the demonstration plan. 3.3.1 Technology Description The Ah-IMMUNOASSAY® makes it possible to screen large numbers of samples to eliminate non-positives before subjecting the positive samples to further analysis. The Ah-IMMUNOASSAY® takes advantage of the correlation between the toxicity of dioxin-like compounds and their interaction with the Ah-receptor. The Ah-IMMUNOASSAY® measures the ability of the test mixture to interact with the Ah-receptor, thus providing data for the total toxicity of the mixture as 2,3,7,8-TCDD equivalents. Samples to be tested in the Ah-IMMUNOASSAY® are added to a reagent mixture containing Ah-receptor and other components in a special ELISA plate and allowed to incubate at room temperature for two hours. At that time, any Ah-receptor transformed by dioxin-like compounds is bound to the plate, and the remaining material is washed away. Antibodies are added to the ELISA to detect the transformed, bound Ah-receptor, which is in turn detected colorimetrically. Color development is directly proportional to the amount of transformed Ah-receptor. The detection limit is one pg 2,3,7,8-TCDD equivalent per ELISA plate well. The linear range is 1 to 64 pg TCDD equivalents per ELISA plate well. About 2 |il of final sample extract is required per ELISA plate well. The assay does not separate and identify single dioxin congeners, but measures the ability of the test mixture to interact with the Ah-receptor, thus measuring the total toxic potential of the mixture as 2,3,7,8-TCDD equivalents. Duplicate aliquots of each reference standard and sample dilution are recommended. Replicate absorbance readings of OD should show a coefficient of variation of 20% or less. The Ah-IMMUNOASSAY® Kit is supplied as a 96- or a 4 8-well version and contains • Cytosol ORE Oligo • Aryl hydrocarbon receptor nuclear translocator (ARNT) extract Figure 3-5 . Paracelsian, Inc., Ah- Activator EMMUNOASSAY®. • Mixing tube (50 mL) • Reagent reservoirs • ELISA plate and cover 20 Wash buffer AB 1 and AB 2 (Antibodies 1 and 2) • AB diluent • Detection tablets • Detection buffer • Positive control (a-napthoflavone or 7,8-benzoflavone). 23 ------- The Activated Cytosol components (Cytosol, DRE Oligo, ARNT Extract, and Activator) are shipped separately on dry ice. These components are stable for a minimum of one month when stored at -20°C and for three months when stored at -80°C. The remaining components are shipped at ambient temperature but should be refrigerated once received. They are stable for a minimum of one year when stored at 4°C. The user is to supply calibration standards (normally 2,3,7,8-TCDD) and any materials needed to prepare samples for analysis in dimethyl sulfoxide (DMSO). 3.3.2 Operating Procedure The following protocol is for an assay that uses all wells of the 96-well version of the kit. Steps 18 through 21, describing the procedure for the three replicate washes following each incubation, can be automated by a commercial plate washer. Likewise, any residual fluid remaining in the plate wells can be completely removed by a properly adjusted plate washer, thereby eliminating the need for the manual blotting in step 31. 1. Remove the refrigerated components of the kit from cold storage and warm to room temperature. 2. Remove the cytosol components (cytosol, DRE Oligo, ARNT extract, activator) from frozen storage. Thaw up to four 7.5-mL vials of cytosol in a beaker of tepid water. Steps 3 through 9 will generate the activated cytosol. Keep all intermediate mixtures in an ice bath as much as possible. 3. Pool the thawed tubes of cytosol into the 50-mL mixing tube. 4. Add the required volume of DRE Oligo to the pooled cytosol. Return any unused DRE Oligo to the freezer. 5. Mix by gently rocking the tube. 6. Add the required volume of ARNT to the cytosol, DRE Oligo mixture. Return any unused ARNT to the freezer. 7. Mix by gently rocking the tube. 8. Add the required volume of activator to the cytosol, DRE Oligo, ARNT mixture. Return any unused activator to the freezer. 9. Mix immediately (to avoid high local concentrations of salt) by gently rocking the tube. This mixture is the activated cytosol and must be kept on ice. 10. Add 10 (iL each of one reference standard, one negative control, and up to 10 samples in DMSO (the negative control) to 1.0-mL aliquots of the activated cytosol and gently mix. Tubes for these preparations are supplied by the user. These mixtures compose the treated stock for each type of determination. 11. The 96-well ELISA plate layout will accommodate one negative control, seven dilutions of the TCDD reference standard (or a single dilution of the NAP Standard), and four dilutions of 10 24 ------- samples, all in duplicate. If less than 96 wells are used, return the unused ELISA strips to 4°C storage in the foil bag with desiccant. 12. Remove the ELISA plate from the desiccated plastic bag and add 400 (iL of each treated stock to the top row of the wells to give duplicate runs of each of the 10 samples and the single reference standard. 13. With a multichannel pipettor, add 200 (iL of activated cytosol to all the remaining wells. One of the kit reservoirs will facilitate loading the pipettor. 14. Beginning with the first sets of duplicate wells, make serial dilutions (seven dilutions for the TCDD reference or the single dilution of the NAP, four dilutions for each sample) down the respective plate columns. Individual dilutions are mixed by a minimum of six repetitive aspiration and redispensing cycles of the well contents. The residual waste following the final dilution must be collected for proper disposal. 15. Attach the lid to the plate. 16. Incubate the plate for two hours at 30°C. Incubation at room temperature (i.e., 20°C) is satisfactory, but will result in a slightly lower response. Incubation at a higher temperature (i.e., 37°C) will also result in a lower response. 17. Prepare the IX wash buffer by diluting the contents of the 20 X wash buffer bottle to 500 mL with reagent-grade water (250 mL for the 48-well kit). Store unused 1 X wash buffer at 4°C. 18. After the two-hour incubation, remove the well contents by aspiration into a waste receptacle for proper disposal. 19. Add 400 (iL IX wash buffer to all wells, loading the multichannel pipette from a kit reservoir. 20. Wait two minutes. Remove the well contents by aspiration into the waste receptacle for proper disposal. 21. Repeat steps 19 and 20 twice for a total of three separate washes. 22. Prepare the primary antibody stock by aliquoting the required amount of AB 1 into the appropriate volume of AB diluent. Mix gently. Store unused AB 1 and AB diluent at 4°C. 23. Deliver 200 (iL AB 1 stock to all wells of the plate, loading the multichannel pipette from a kit reservoir. 24. Incubate the plate for one hour at 30°C. 25. After the one hour incubation, repeat steps 18 through 21. 26. Prepare the secondary antibody stock by aliquoting the required amount of AB 2 into the appropriate volume of AB diluent. Mix gently. Store unused AB 2 and AB diluent at 4°C. 25 ------- 27. Deliver 200 (iL AB 2 stock to all wells of the plate, loading the multichannel pipette from a kit reservoir. 28. Incubate the plate for one hour at 30°C. 29. After the one-hour incubation, repeat Steps 18 through 21. 30. Prepare the detection reagent stock by dissolving the required number of detection tablets in the appropriate volume of detection buffer with gentle mixing while protected from light. Allow a minimum of 15 minutes for the tablets to completely dissolve. Unused detection buffer and tablets are kept at 4°C. 31. Following the incubation of the final wash, strike the inverted plate against paper toweling to remove residual fluid before proceeding to the next step. 32. Deliver 200 (iL of the detection reagent stock from step 30 to all wells of the plate, loading the multichannel pipette from a kit reservoir. 33. Incubate the plate at 30°C while protected from light. Residual moisture from condensation and/or from contact with incubator water must be carefully blotted from the plate before reading. The plate is read at 405 nanometers (nm) after 15, 30, 45, and 60 minutes. Variations in incubation temperatures and plate reader characteristics may dictate the best incubation times for individual conditions. A standard curve is used to determine the amount of TCDD equivalents present in a sample. The standard curve is generated by plotting the average absorbance (OD) measured at 405 nm for each of the TCDD reference standards on the vertical (Y) axis versus the corresponding quantity (pg) of TCDD on the horizontal (X) axis. Results are calculated manually using graph paper or a curve-fitting statistical software package. The TCDD equivalents for the samples are determined from the standard curve by interpolating from the absorbance value (Y axis) to the quantity (pg) of TCDD (X axis). The initial TCDD concentration in the sample is found by correcting for the sample dilution. The supplied NAP solution, at 2 (iL per test well, may optionally be used as a single-point positive control that is equivalent to 32 pg TCDD. 3.3.3 Advantages and Limitations Equipment required for the test is relatively inexpensive and readily available. The Ah-IMMUNOASSAY® is simple to perform and highly reproducible. It is very sensitive to the respective toxicity of the dioxins and related compounds of interest. Toxicity is measured as the ability of the sample to transform the AhR. The result, therefore, denotes total toxicity from all toxins that are present in the sample. The assay does not identify individual dioxin congeners. Competing enzyme immunoassay methods are less sensitive, typically detecting only certain dioxin congeners without direct correlation to total toxicity. Some related toxic compounds are not detected at all by direct immunoassays. False negatives results with the Ah-IMMUNOASSAY® are rare. Positive results can be further characterized by selective pretreatment steps or by specific GC/MS testing. 26 ------- 3.4 Abraxis LLC Coplanar PCB ELISA Kit The Abraxis coplanar PCB ELISA kit applies the principle of enzyme immunoassays for the qualitative or semi-quantitative analysis of coplanar PCBs in a variety of sample extracts. Extracts from soil, sediment, fish tissue, and others matrices can be exchanged to methanol for ELISA analysis. Water samples can be diluted 1:1 in methanol and analyzed directly in the assay. The technology description, operating procedure, and advantages and limitations below are based on information provided by Abraxis LLC. and only editorial changes were made by Battelle to ensure document consistency and meet the needs of the demonstration plan. 3.4.1 Technology Description The Abraxis coplanar PCB ELISA kit (Figure 3-6) can screen samples according to their TEQ concentration. The specificity of the test is predominantly for those congeners with high TEF values; i.e. congeners 126 and 169. Samples extracted with organic solvents that are incompatible with ELISA can be evaporated and re-dissolved in methanol. For a quick screen of soil and sediment samples, the samples can be extracted in 20% acetone in hexane, diluted 1:10 in the provided diluent, and run directly in the assay. A solution containing a primary antibody (rabbit) that reacts with coplanar PCBs is added to a microplate containing a secondary antibody that captures the primary antibody. Calibrators (congener 126) and samples are added and allowed to incubate, followed by the addition of a coplanar . __„ rT D/-D tron •+ A i D/-D +u 4. Figure 3-6. Abraxis PCB ELISA Kit PCB-HRP enzyme conjugate. Any coplanar PCBs that may be in the sample competes with the coplanar PCBs enzyme label conjugate for a finite number of antibody binding sites. At the end of the incubation period, the unbound conjugate is removed, and the plate is washed. A substrate/chromogen solution is then added and enzymatically converted from a colorless to a blue solution by the captured coplanar PCB-HRP conjugate on the plate. The reaction is then terminated by acidification. The coplanar PCBs concentration is determined by measuring the absorbance (at 450 nm) of the sample solution using a microplate reader and comparing it to the absorbance of the calibrators. The amount of color produced is inversely proportional to the amount of coplanar PCBs present in the sample. The final value measured by ELISA is the sum of the various congeners responses, this value approximates TEQPCB because of the immunoassay kit cross-reaction profile for coplanar PCBs approximates TEF values. Accuracy among samples may vary solely because of the variability of congener composition. To help maximize accuracy, the variability of congener composition in the target sample should be known. The primary use of the Abraxis coplanar PCB ELISA kit is to screen samples that have low coplanar PCB concentrations. The sensitivity of the test in water samples is claimed by Abraxis to be 4 parts per trillion (pg/mL). This value must be related to the original sample concentration by using the appropriate dilution and volume factors. Detection levels depend on how much sample is evaporated and the volume of solvent used to resuspend the sample. Matrix detection limits will vary according to the matrix being analyzed, sample size, and dilution factor. Up to 100 samples per day can be analyzed using the procedure described below. 27 ------- The Abraxis coplanar PCB ELISA Kit consists of 1.

Washing Buffer 5X Concentrate Buffer salts with detergent and preservatives. 96-testkit: one 100-mLvial 3.4.2 Operating Procedure To ensure accurate and reliable results, every effort should be made to perform the coplanar PCB ELISA at temperatures between 20°C and 25°C and to allow the reagents to be at the same temperature. The following sample preparation was designed for a quick screen at 625 pg/g. Other sample preparation options are available for lower concentration. 3.4.2.1 Preparation of Sample Extracts From Soil 1. Label soil collection bottles and extract collection vials. 2. Remove the screw cap from the soil collector bottle (containing dispersion device) and collect soil by weight using a digital balance. Place the bottle in an upright position on the balance and tare weight. 28 ------- 3. Weigh 2 g of soil in a 30-mL high-density polyethylene (HDPE) bottle. 4. Add 6 g of anhydrous sodium sulfate and mix until sample is free flowing. 5. Add 1 steel mixing ball. 6. Add 10 mL of 20% acetone in hexane. Rotate for one hour. 7. Remove the organic extract from the soil particulates by filtration, sedimentation, or centrifugation. 8. Transfer extract to a 40 mL screw cap extraction tube and oxidize using concentrated sulfuric acid (4 mL). Mix by agitation for a minute and allow phases to separate. 9. Remove the organic phase (top layer), transfer to a fresh extraction tube and add 4 mL of concentrated sulfuric acid. Mix by agitation for a minute and allow phases to separate. 10. Repeat step 9 until the acid phase is colorless. 11. Evaporate 1 mL of the organic phase using a nitrogen stream. 12. Redissolve in 0.25 mL of methanol. 13. Add 0.25 mL of water. If cloudy, centrifuge. NOTE: This extraction procedure dilutes the sample by a factor of 2.5. Therefore, assay results need to be multiplied by 2.5 to obtain the final coplanar PCB concentration in the sample. 3.4.2.2 Dilution of Sample Extracts Dilute sample (1:10) by adding 50 |iL of extract to 450 |iL of diluent/zero standard (provided). 3.4.2.3 Assay Procedure 1. Add 50 |iL of anti-coplanar PCB antibody solution successively to each well. 2. Add 50 |iL of the appropriate standard, control, or sample. Using duplicates or triplicates is recom- mended. Cover the wells with parafilm or tape and mix the contents by moving the strip holder in a circular motion on the benchtop. Be careful not to spill the contents. Incubate at room temperature for 30 minutes. 3. After the incubation, remove the covering and add 50 |il of enzyme conjugate solution to the individual wells. Cover the wells with parafilm or tape and mix the contents by moving the strip holder in a circular motion on the benchtop. Be careful not to spill the contents. Incubate at room temperature for 90 minutes. 4. After the incubation, remove the covering and vigorously shake the contents of the wells into a waste container. Wash the strips 3 times using the 1 X wash solution with a volume of at least 250 uL for each wash step. Any remaining buffer in the wells should be removed by patting the plate on a dry stack of paper towels. 29 ------- 5. Add 150 uL of color solution successively to each well. Incubate for 20 to 30 minutes. 6. Add 50 uL of stopping solution to each well in the same sequence as for the other reagents. 7. Read absorbance using a microplate reader at 450 nm within 15 minutes after adding the stopping solution. 8. Construct a standard curve by plotting the %B/B0 for each standard on a vertical logit (y axis) versus the corresponding PCB 126 standard concentration on the horizontal logarithmic axis (x) on a graph paper. Alternatively, commercial ELISA programs can be used (4-parameter or logit-log). 9. To obtain the total coplanar PCB TEQ in a sample, multiply sample assay results by the cross- reactivity factor 0.01. 3.4.3 Advantages and Limitations The Abraxis coplanar PCB ELISA kit can detect the total coplanar PCBs at various levels and eliminates the complex extraction and clean-up steps used with GC/MS. The coplanar PCB kit can be used in the field or laboratory. The low part per trillion (ppt) sensitivity of the kit is competitive with HRMS. The distribution of coplanar PCBs can be heterogeneous. Adequate number (statistically significant), distribution, and homogeneity are the responsibility of the analyst. Samples that appear heterogeneous during assay incubations (cloudiness) are invalid. Adequate sample cleanup must be assured by the analyst. The Abraxis coplanar PCB kit is cost-effective compared to other methods; however, it is a screening method only. The method does not provide quantitative results because of the variability of concentrations of individual congeners in real samples. The relationship between immunoassay response and TEQ may vary significantly for different samples. This ELISA kit provides an approximation. Forty samples can be analyzed in less than 4 hours from sample extraction to results. 3.5 Wako Dioxin ELISA Kit The Wako Dioxin ELISA Kit from Wako Pure Chemical Industries, Ltd. was developed to screen minute amounts of dioxin. With a microplate reader, samples can be assayed simultaneously for PCDD/Fs. The technology description, operating procedure, and advantages and limitations below are based on information provided by Wako Pure Chemical Industries, Ltd. and editorial changes were made by Battelle to ensure consistency and to meet the needs of the demonstration plan. 3.5.1 Technology Description A monoclonal antibody specific to dioxin is mixed with a sample solution or the positive control (PC) provided with the Dioxin ELISA Kit. Peroxidase conjugated with a dioxin analog (POD-conjugate) is then added, reacting with a primary antibody to dioxin in the sample. The mixture is added to a 30 ------- microplate coated with a secondary antibody that captures the antibody-POD-conjugate and incubated at 2° to 8°C for 18 to 20 hours. After washing the resultant microplate with a buffer, the antibody-POD-conjugate complex formed on the plate is reacted with substrate for peroxidase. The reaction is stopped by adding stop solution, and the microplate reader reads the signal. The Dioxin ELISA Kit contains the secondary antibody microplate, the PC, buffers A and B, the primary antibody, peroxidase conjugate (lyophilized), sample solubilizer, wash solution concentrate, substrate, citrate buffer, stop solution, and a plate seal. The monoclonal antibodies used for the Dioxin ELISA Kit indicate cross-reactivity nearly equal to the positive control (2,7,8-trichlorodibenzo [1,4] dioxin-1-yl) acrylic acid) and 2,3,7,8-TCDD. It is possible to find dioxin concentrations as the amount equivalent to 2,3,7,8-TCDD TEQ. The Dioxin ELISA Kit sensitivity is claimed by Wako to be 1.6 to 100 pg per assay, and 96 samples can be assayed in two days. The procedure is summarized in Figure 3-7. 3. 5. 2 Operating Procedure The Dioxin ELISA Kit should be used at room temperature (20° to 25°C) and stored at 2°tolO°C. 1 . To prepare the PC solution (5,000 pg/mL), add 2.0 mL of methanol to the tube containing the positive control (PC). Then, gently stir the tube four or five times, and leave it at room temperature for 10 minutes. Gentle stirring is repeated once more before use. Do not vigorously shake or vortex the solution to avoid PC material adhering to the tube wall. The solution can be used within four weeks at 2° to 10°C after reconstitution. 2. Prepare the dilution solution by dispensing 2 mL of sample solubilizer in a tube and adding 2 mL of methanol. POD-Conjugate Sample or PC Reaction of POD- conjugate and un reacted "* antibody \ Add to microplate well , with secondary A Antibody fixation plate Y I V V I I Y V I Fix reactants to microplate well 3 . Prepare 1/10-fold diluted PC solution (500 nanograms/mL) by adding 900 |iL of dilution solution to a disposable culture tube rinsed with acetone and dried. Then add 100 |iL of concentrated PC solution and gently stir the tube two or three times. Leave the tube at room temperature. React the POD with the substrate for coloring. Then measure the color density with the microolate reader. Figure 3-7. Wako Dioxin ELISA Kit procedure. 4. Prepare PC dilution solutions for the standard curve using the 1/10-fold diluted PC solution described above as follows: 31 ------- Tube Number: Concentration Dilution solution Concentrated PC solution 1/1 0-fold diluted PC solution Total volume 1 0 pg/mL 500 |iL — 0|iL 500 |JL 2 40 pg/mL 460 |iL — 40|iL 500 |JL 3 lOOpg/mL 400 |iL — 100 |iL 500 ML 4 250 pg/mL 250 |iL — 250 |iL 500 ML 5 500 pg/mL 450 |iL 50|iL — 500 ML 6 l,OOOpg/mL 400 |iL 100 |iL — 500 ML 7 2,500 pg/mL 250 |iL 250 |iL — 500 ML 5. Dry the contents of each tube. 6. To prepare a dilution series of PC solutions, add 500 |iL of Buffer B to each tube, lightly stir it with a vortex mixer, and centrifuge at 2,000 revolutions per minute (rpm) at room temperature to collect the liquid at the bottom. 7. To prepare the primary antibody stock solution, add 200 |iL of purified water to the tube and gently stir, then leave the tube for 10 minutes at room temperature. The solution can be used within four weeks. 8. Rinse a beaker or a 5- to 10-mL vial with acetone and air dry on clean paper towels. 9. Prepare the primary antibody working solution using a 100-fold dilution of the primary antibody stock solution described above with Buffer A according to assay sample numbers and volumes. Stir the diluted solution gently several times, and leave it at room temperature for 10 minutes. Stir the solution several times just before use. This solution cannot be stored prior to use. 10. Prepare the POD-conjugate solution by adding 4 mL of Buffer A to the tube and gently stir several times. Leave the tube at room temperature for 10 minutes. Gently stir the tube just before use. The solution can be used within two weeks when stored at 2° to 10°C. 11. Fix the necessary number of microplate wells (coated with the secondary antibody) to a microplate holder with Scotch® tape. Place the holder in a closed box, and store it in a refrigerator for at least 30 minutes before use. 12. Add 100 |iL of Buffer B to the tube containing the material obtained by sample pretreatment and gently stir the solution along the inner surface of the tube several times with vortex mixer. Briefly centrifuge the tube at 2,000 rpm for five minutes to collect the solution at the bottom. 13. Line up the tubes containing the dilution series of PC solutions and the samples dissolved in Buffer B in a tube rack. Dispense an equal volume of the primary antibody working solution to each tube. 14. Immediately agitate the solutions several times, then seal the tubes with Parafilm and leave them at room temperature for 30 minutes. 15. During the incubation, prepare chilled water containing ice in a water bath and immerse the tubes in the bath. After the 30 minute-incubation at room temperature, add 250 |iL and 50 |iL of POD-conjugate solution to the tubes containing the diluted PC solutions and those containing sample material, respectively. 16. Gently agitate the tubes several times and leave them for 10 minutes. Avoid vigorous shaking with the vortex because dioxins may adsorb to the tube wall. 32 ------- 17. Take the microplate holder from the box stored in a refrigerator. Dispense 100 |iL of the reaction mixture to the wells. Briefly agitate the solutions in the wells. Seal the wells with Parafilm, return the holder to the box, and store the box in a refrigerator at 2° to 10°C for 18 to 20 hours. 18. On the second day, prepare the wash solution by diluting the wash solution concentrate (X6) with five volumes of purified water. The solution volume prepared can be adjusted depending upon the number of wells used. Usually, one well needs 1.2 mL of the wash solution. The solution can be used within two weeks after dilution when stored at 2° to 10°C. 19. Prepare the necessary volume of color-developing solution by mixing the substrate and the citrate buffer in a ratio of 1:50 just before use. (The tube used in this preparation should be cleaned with purified water.) Add the citrate buffer to the tube, then the substrate. Avoid vigorous agitation of the mixed solution because it may cause crystalization. 20. Take the well holder from the box stored in a refrigerator and remove the seal from the wells. Remove the reaction mixture from the wells, being careful not to spill the solution to the holder. Lightly tap the holder upside down on sheets of paper to remove the residual mixture in the wells. Dispense approximately 0.35 mL of wash solution to each well and then drain the solution, being careful not to spill the solution. Remove the solution from the well walls by tapping the holder upside down on the papers. Repeat washing twice. At the last washing, remove the solution by tapping as much as possible. 21. For the enzyme reaction, dispense 100 |iL of the color-developing solution to all the wells. Seal with Parafilm, cover the holder with aluminum foil to block out light, and leave the holder at room temperature for 30 minutes. Stop the reaction by adding 100 |iL of stop solution in the same well sequence as the color-developing solution. Tap the side of the holder to mix the solution. Read the signal with a microplate reader at 450 nm or at 450/650 nm within 15 minutes after stopping the reaction. Construct the standard curve obtained with the diluted PC solutions and estimate the dioxin concentrations of samples as 3,7,8-TCDD. The primary antibody used in this kit reacts with 2,3,7,8-TCDD and 3,7,8-TCDD with equal intensity. 22. In estimating the dioxin concentration, it is useful to plot the obtained values with a regression of polynomial quadratic equation or four-parameter logic after log-logit conversion. 3.5.3 Advantages and Limitations Highly sensitive analysis is possible with the Dioxin ELISA Kit. A non-toxic standard (2, 7, 8-trichlorodibenzo [1,4] dioxin-1-yl) acrylic acid) is used. The 96-microplate format makes possible a simultaneous multisample assay. The assay process takes only two days. 3.6 Xenobiotic Detection Systems, Inc., CALUX® CALUX® (chemical-activated luciferase expression) by Xenobiotic Detection Systems Inc. (XDS) technology is based on a reporter gene system using a genetically engineered cell line capable of detecting all of the WHO-recognized dioxins, furans and PCBs. Giving results for dioxins/furans and PCBs 33 ------- separately or together, as well as being available as a screening and/or quantitative analysis. CALUX® by Xenobiotic Detection Systems is used to analyze soil, sediment, fly ash, stack gas emissions, food, feed, blood, and any other substance suspected of being contaminated with dioxins/furans and PCBs. The technology description, operating procedure, and advantages and limitations provided below for the CALUX® are based on information provided by Xenobiotic Detection Systems, Inc. and editorial changes were made by Battelle to ensure consistency and to meet the needs of the demonstration plan. 3.6.1 Technology Description XDS has patented (patent # 5,854,010) a genetically engineered cell line that contains the firefly luciferase gene under trans-activational control of the AhR. This cell line can be used for the detection and quantification of the AhR agonists, the target receptor of dioxins, furans, and PCBs. The XDS term for the in vitro assay is the Chemical-Activated Luciferase Expression (CALUX®) by Xenobiotic Detection Systems assay. The most widely studied compounds that activate this system are the polychlorinated diaromatic hydrocarbons (PCDH), such as 2,3,7,8-TCDD. Many PCDH compounds are quantified relative to TCDD, since this is one of the most potent activators of AhR-mediated gene transcription. These relative quantifications are known as TEQs, and the results from the CALUX® by Xenobiotic Detection Systems assay provide a measure of TEQs in a sample. By using proprietary cleanup methods developed by XDS, it is possible to separate PCBs from dioxins/dibenzofurans and to determine what portion of the total TEQ in a sample is due to each of these classes of compounds. XDS has termed this procedure the Dioxin/Furan and PCB-Specific (DIPS) or DIPS-CALUX® by Xenobiotic Detection Systems bioassay. Prices start at $200.00 for a dioxin screening (single) analysis and $250.00 for a dioxin and PCB analysis, with analysis provided as a fee for service at the XDS laboratories. Field analysis is available with 96 well plates being shipped to the site for analytical procedures to be performed by trained personnel. Costs per 96 well plates are approximately $2,400, with each plate capable of analyzing up to 40 samples along with standard curves and quality control standards. Rental of equipment and proprietary software to perform the CALUX® by Xenobiotic Detection Systems is also available. 3.6.2 Operating Procedure Xenobiotic Detection Systems, Inc. has a patented genetically engineered cell line (mouse hepatoma H1L1) that contains the gene for firefly luciferase under transactivational control of the AhR. This cell line can be used for the detection and relative quantification of a sample's total dioxin I-TEQ. The XDS CALUX® bioassay for dioxin-like chemicals uses a patented sample processing procedure (U.S. patent # 6720431) that allows separation of coplanar PCBs and PCDDs/PCDFs so that estimates of I-TEQ can be made for each chemical class. This allows reporting of I-TEQ estimates for chlorinated dioxins/furans and for the PCBs. The samples are extracted using a modification of the EPA 8290 extraction method. Briefly, the dried samples are ground and 1-g aliquots are placed in solvent-cleaned glass vials with polytetrafluoroethylene-lined caps. The sample is extracted with a 20% solution of methanol in toluene then twice with toluene. During each extraction step, the samples are incubated in an ultrasonic water bath. The three extracts from each sample are filtered, pooled, and concentrated by vacuum centrifugation. The sample extract is suspended in hexane and rapidly processed through a patented (U.S. patent # 6720431) two column chromatographic procedure to produce two extracts, one containing chlorinated dioxins/furans and one containing PCBs (see Figure 3-8). The extracts are exchanged into 34 ------- DMSO and used to dose the genetically engineered cells in the CALUX® assay by XDS to provide I-TEQ estimates for PCBs and PCDD/PCDFs. Prior to dosing the cells, the sample extracts in DMSO are suspended in cell culture medium. This medium is then used to expose monolayers of the H1L1 cell line grown in 96-well culture plates (see Figure 3-9). In addition to the samples, a standard curve of Figure 3-9. Luminescence produced when CALTJX® cells are exposed to dioxin and dioxin-like chemicals. Figure 3-8. Xenobiotic Detection Systems patented sample processing procedure. 2,3,7,8-TCDD is assayed (161, 80.5, 40.2, 20.1, 10.1, 5.0, 2.5, 1.2, and 0.6 ppt TCDD). The plates are incubated for a time to produce optimal expression of the luciferase activity in a humidified CO2 incubator. Following incubation, the medium is removed and the cells are examined microscopically for viability. The induction of luciferase activity is quantified using the luciferase assay kit from Promega. 3.6.3 Advantages and Limitations CALUX® by Xenobiotic Detection Systems analyses are approximately 25% of the cost of FIRGC/MS analyses, and sample sizes are small (10 g or less). Results can be made available within 28 hours in emergency situations. Expenses for laboratory setup are minimal, and the proprietary cleanup method eliminates false positives and false negatives. CALUX® by Xenobiotic Detection Systems analyzes environmental, foodstuff, and biological samples. CALUX® by Xenobiotic Detection Systems also analyzes all 17 lexicologically active dioxin and 12 PCB congeners, and results are reproducible. Detection limits below 0.5 ppt TEQ scores are provided for both dioxin and PCB analyses. CALUX® by Xenobiotic Detection Systems does not, however, identify individual congeners. CALUX® by Xenobiotic Detection Systems has been authenticated as a European Union-certified screening tool for dioxin in foodstuffs by BELTEST. 35 ------- Chapter 4 Sample Collection, Sample Homogenization, and Sample Characterization This chapter discusses the sample collection, sample homogenization, and sample characterization procedures used in the demonstration. 4.1 Sample Collection This section describes the environmental sample collection activities performed at various sites across the country. Battelle performed an intensive search for sampling sites that had varying levels of dioxin contamination in either soil or sediments. This diversity will make the demonstration results more applicable to a larger user community, as well as to challenge the technologies using a variety of sample compositions. Samples were collected by EPA, an EPA contractor, or MDEQ and shipped to Battelle. When determining if a soil or sediment site had appropriate dioxin contamination, a guideline concentration range was provided to sample providers of < 50 pg/g to 5,000 pg/g. It was understood that this concentration range was to be used as a general guideline, and that those providing the sample descriptions were to provide concentration data based on best available information. 4.1.1 Procedure This section describes the method that was used to collect the samples by each of the site personnel. Once necessary approvals and sampling locations had been secured, site personnel were shipped sample containers. Each site providing samples received one-gallon containers (Environmental Sampling Supply, Oakland, California, Part number 3785-1051, wide-mouth, 128-ounce HDPE round packer) for the collection of five or six samples. At least 2 gallons of material (soil or sediment) for each sample were needed; therefore, if a site was providing six samples, twelve 1-gallon containers were shipped to the site for the collection of six 2-gallon samples. With the 12 containers provided, it was anticipated that the six sample containers were filled in duplicate. Shipments consisted of pre-cleaned, 1-gallon sample containers with instructions on how to fill the containers for each sample collected. Instructions for sample collection as well as how the containers were to be labeled and returned were included in a cover letter (see example in Appendix C) with the sample containers that were shipped to each site. Personnel collecting the samples were instructed to label two containers containing the same sample as "1 of 2" and "2 of 2" and to attach a description or label each container with a description of the sample including where the sample was collected and the estimated concentrations of dioxin and any other anticipated contamination (e.g., PCBs, PAHs, pentachlorophenol [PCP]). Final instructions to sample providers indicated that collected samples were to be shipped back to Battelle using the provided coolers. Federal Express labels that included an account number and the shipping address were enclosed in each shipment. 36 ------- Sample providers also were asked to provide any information about the possible source of contamination or any historical data and other information such as descriptions of the sites for inclusion in the demonstration plan. 4.1.2 Sample Shipping to and Archival at Battelle The samples were received at Battelle in the same coolers that were used to send the containers to the field. The environmental samples were stored at room temperature until homogenized. 4.2 Homogenization of Environmental Samples If the material had very high moisture content, the jar contents were allowed to settle and the water was poured off. Extremely wet material was poured through fine mesh nylon material to remove water. After water removal, the material was transferred to a Pyrex™ pan and mixed. After thorough mixing, an aliquot was stored in a pre-cleaned jar as a sample of "unhomogenized" material and was frozen1. The remaining bulk sample was mixed and folded bottom to top three times. This material was split equally among multiple pans. In each pan, the material was spread out to cover the entire bottom of the pan to an equal depth of approximately 0.5 inch. The pans were placed in an oven at 35 °C and held there until the samples were visibly dry. This process took 24 to 72 hours, depending on the sample moisture. The trays were removed from the oven and allowed to come to room temperature by sitting in a fume hood for approximately 2 hours. Approximately 500 g of material was put in a blender and blended for 2 minutes. The blender sides were scraped with a spatula and the sample blended for a second 2-minute period. The sample was sieved (USA Standard testing, No. 10, 2.00-millimeter [mm] opening) and the fine material placed in a tray. Rocks and particles that were retained on the sieve were placed in a pan. This process was repeated until all of the sediment and soil was blended and sieved. The blended and sieved sediment/soil in the tray were mixed well, and four aliquots of 100 to 300 g each were put into clean jars (short, wide-mouth 4-ounce , Environmental Sampling Supply, Oakland, California, Part number 0125-0055) to be used for the characterization analyses. The remaining sediment or soil was placed in a clean jar, and the particles that were retained on the sieve were disposed of. The jars of homogenized sediment and soil were stored frozen (approximately -20°C), unless the samples were being actively used over a period of several days, at which time they were temporarily stored at room temperature. It should be noted that none of the technologies participating in this demonstration require that samples be dried prior to analysis. As such, moisture effects on technology performance that will commonly be encountered with real-world soil and sediment samples, will not be evaluated during this demonstration. 4.2.1 Criteria for Determining Adequate Homogenization Two criteria had to be met in order for the sample to be considered adequately homogenized. The first criteria was that the relative standard deviation (RSD) of the total D/F TEQ values from the four aliquots had to be less than 20%. For samples with total TEQ values < 50 pg/g, RSD values up to 30% were con- sidered acceptable. The second criteria was that no single RSD for an individual congener could be greater than 30%. If both of these criteria were met, the sample was considered homogeneous and considered for inclusion in the demonstration. If either of these criteria were not met, options for the Ideally, the samples would have been stored at 4° ± 2° but due to the large volume of buckets and jars that needed to be stored, the most adequate available storage at Battelle was a walk-in freezer that was at approximately minus 20°C. 37 ------- sample included: (a) discard it and not consider it for use in the demonstration, (b) reanalyze it to determine if the data outside the homogenization criteria were due to analytical issues, or (c) rehomogenize and reanalyze it. Of these options, (a) and (b) were utilized, but (c) was not because an adequate number of environmental samples were selected using criteria (a) and (b). All samples included in the demonstration met the criteria for acceptable homogenization. In a few cases, the composition of a particular sample was of interest for inclusion in the demonstration because of concentration or unique congener pattern, but the homogenization criteria were slightly exceed (i.e., no more than 30% RSD for TEQ and no more than 40% RSD for a particular congener). Since multiple replicates of every sample will be analyzed in the design, it was the recommendation of the demonstration panel (Appendix A) to still include that sample in the study because of the unique nature of the sample, but flag it as slightly exceeding the homogenization criteria. 4.3 Characterization of Environmental Samples A total of 58 environmental samples were received from ten different sampling locations (see descriptions in Chapter 5). All of the environmental samples were homogenized, as described in Section 4.2, and analyzed by Battelle. The environmental samples were characterized for the 17 D/Fs by Method 1613B, the 12 WHO PCBs by LRMS Method 1668A, and 18 target PAHs by National Oceanic and Atmospheric Administration Status and Trends GC/MS method. All characterization analyses were performed by Battelle in their laboratories. The purpose of the characterization analyses was two-fold. First, the analyses determined the adequacy of the homogenization. Second, the approximate concentrations of the target analytes were determined. These two pieces of information served as the basis of sample selection for inclusion in the demonstration. 4.3.1 Dioxins and Furans Four aliquots of homogenized material and one unhomogenized (i.e., "as received") aliquot were prepared and analyzed for seventeen 2,3,7,8-substituted dioxins and furans following procedures in EPA Method 1613, Revision B. The homogenized and unhomogenized aliquots were each approximately 200 g. Depending on the anticipated levels of dioxins from preliminary information received from each sampling location, approximately 1 to 10 g of material was taken for analysis from each aliquot and spiked with 13C12-labeled internal standards, and extracted with methylene chloride using accelerated solvent extraction (ASE) techniques. One method blank and one laboratory control spike were processed with the batch of material from each site. The sample extracts were processed through various cleanup techniques, which included gel permeation chromatography or acid/base washes, as well as acid/base silica and carbon cleanup columns. As warranted based on sample compositions, some samples were put through additional acid silica cleanup prior to the carbon column cleanup. Extracts were spiked with 13C12-labeled recovery standards and concentrated to a final volume of 20 to 50 (iL. Dilution and reanalysis of the extracts were performed if high levels of a particular congener were observed in the initial analysis. Each extract was analyzed by GC/FIRMS in the selected ion monitoring (SIM) mode at a resolution of 10,000 or greater. A DB5 column was used for analysis of the seventeen 2,3,7,8-PCDD/F congeners. The instrument was calibrated for PCDD/F at levels specified in Method 1613 with one additional calibration standard at concentrations equivalent to one-half the level of Method 1613's lowest calibration point. Using a DB5 column, 2,3,7,8-TCDF is not separated from other non-2,3,7,8-TCDF isomers. However, since the primary objective was to determine adequacy of homogenization and not congener quantification, it was determined that sufficient information on precision could be obtained with the DB5 38 ------- analysis of 2,3,7,8-TCDF and no second column confirmation of 2,3,7,8-TCDF was performed. PCDD/PCDF data were reported as both concentration (pg/g dry) and TEQs (pg TEQ/g dry). 4.3.2 PCBs One aliquot of material from each sampling location was prepared and analyzed for the 12 WHO- designated dioxin-like PCBs by LRMS. Battelle's LRMS PCB analysis method is based on key components of the PCB congener analysis approach described in EPA Method 1668A and the PCB homologue approach described in EPA Method 680. Up to 30 g of sample was spiked with surrogates and extracted with methylene chloride using shaker table techniques. The mass of sample extracted was determined based on information supplied to the laboratory regarding possible contaminant concentrations. The extract was dried over anhydrous sodium sulfate and concentrated. Extracts were processed through alumina column cleanup, followed by high-performance liquid chromatography/gel permeation chromatography (HPLC/GPC). Additionally, sulfur was removed using activated granular copper. The post-FiPLC extract was concentrated and fortified with recovery internal standards. Extracts were concentrated to a final volume between 500 (iL and 1 mL, depending on the anticipated concentration of PCBs in the sample, as reported by the sample providers. PCB congeners and PCB homologues were separated via capillary gas chromatography on a DB5-XLB column and identified and quantified using electron ionization mass spectrometry. This method provides specific procedures for the identification and measurement of the selected PCBs in SIM mode. 4.3.3 PAHs One aliquot of material from each sampling location was analyzed for PAHs. The PAHs were selected by the demonstration panel (see Appendix A). The 18 target PAHs included naphthalene, 2- methylnaphthalene, 2-chloronaphthalene, acenaphthylene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)pyrene, indeno(l,2,3-cd)pyrene, dibenzo(a,h)anthracene, benzo(g,h,i)perylene. Battelle's method for the identification and quantification of PAH in sediment and soil extracts by GC/MS is based on the National Oceanic and Atmospheric Administration (NOAA) status and trends method (8) and, therefore, certain criteria (i.e., initial calibrations and daily verifications) are different than those defined in traditional EPA methods 625 and 8270C. Up to 30 g of sample was spiked with surrogates and extracted using methylene chloride using shaker table techniques. The mass of sample extracted was determined based on information supplied to the laboratory regarding possible contaminant concentrations. The extract was dried over anhydrous sodium sulfate and concentrated. The extract was processed through an alumina cleanup column followed by HPLC/GPC. The post-HPLC extract was concentrated and fortified with recovery internal standards. Extracts were concentrated between 500 (iL and 1 mL, depending on the anticipated concentration of PCBs in the sample, as reported by the sample providers. PAHs were separated by capillary gas chromatography on a DB-5, 60-m column and were identified and quantified using electron impact mass spectrometry. Extracts were analyzed in the SIM mode to achieve the lowest possible detection limits. 4.4 Sample Handling, Sample Tracking, and Sample Management In preparation for the demonstration, the bulk homogenized samples will be split into jars for distribution. Each 4-ounce, amber, wide mouth glass sample jar (Environmental Sampling Supply, Oakland, California, Part number 0125-0055) will contain approximately 50 g of sample. Seven sets of samples will be prepared for the six developers and one reference laboratory. A minimum of four replicate splits 39 ------- of each sample will be prepared for each participant, for a total of at least 28 aliquots prepared for each sample. The purchased PE samples (i.e., standard reference materials and spiked materials) will be transferred from their original packaging to the jars to be used in the demonstration for the environmental samples, such that the environmental and PE samples will be visually indistinguishable. The samples will be randomized in two fashions. First, the order in which the filled jars will be distributed will be randomized, such that the same developer will not always receive the first jar filled for a given sample set. Second, the order of analysis will be randomized so that each developer analyzes the same set of samples, but in a different order. PE materials will be randomized in the same manner, such that the PE samples are indistinguishable from other samples. All jars will have two labels. The label on the top of the jar will be the analysis order (i.e., Developer Name 1) and contain sample numbers 1 through 209. A second label will be placed on the side of the jar will contain a coded identifier including a series of 10 numbers. The 10 numbers will be coded to include the site, replicate, developer, and matrix in the number series that can be readily decoded by Battelle but will be meaningless to the developers so the analyses will occur blindly. Battelle will be responsible for sample distribution during the demonstration. All samples will be prepared for distribution at the start of the verification. When ready to perform analyses, each developer will go to the sample distribution point to pick up the samples. The samples will be distributed in batches of 10 and will be released at each developer's request. More than one batch of 10 samples can be relinquished at a time, if desired by the developer. Completion of a chain-of-custody (COC) form will document sample transfer and will be used to report results. An example COC is included in Appendix D. Samples that have been analyzed by the developer will be turned in to Battelle, along with COC/results form. Results will be entered onto the COC by the developer using black ink. Corrections will be made with a single line/initial/date procedure. During the demonstration, all samples not in the possession of the developer will be stored in the Battelle Headquarters trailer. All trailers will be locked after hours and hired security guards will patrol the site from 7 pm to 7 am. During the demonstration, the samples will be stored at room temperature. There is no concern about significant volatilization of the target contaminants because standard reference materials for dioxins are routinely stored at room temperature, and the samples used in this demonstration will be prepared in a manner similar to how SRMs are processed. An archived set of samples will be at the demonstration site in case a sample is dropped, the integrity is comprised, or ajar is broken during transit to the site. After the demonstration, all unused demonstration samples will be returned to Battelle for archival in a freezer (approximately -20°C) at least until after the reports are final. At the conclusion of the study, the archive set of samples may be provided to EPA for additional use or as reference material. Debris from the demonstration that can be discarded by routine waste removal services will be disposed of from the demonstration site. Sample by-products, including unused sample, aqueous and solvent-based effluents, and miscellaneous used supplies (e.g., glassware, pipette tips, shoe covers, and gloves) will be returned to Battelle for confirmation and quantification of by-products generated by each of the participating technologies. After categorizing and inventorying all of the materials, Battelle will be responsible for final waste disposal. 40 ------- Chapter 5 Descriptions of Demonstration Site and Sampling Locations This chapter describes the demonstration site and the sampling locations and why each was selected. 5.1 Demonstration Site Description This section describes the site selected for hosting the demonstration, along with the selection rationale and criteria. Several candidates host sites were considered. The candidate sites were required to meet certain selection criteria, including necessary approvals, support, and access to the demonstration site; enough space and power to host the technology developers, Battelle, and other participants; and various levels of dioxin-contaminated soil and/or sediment that could be analyzed as part of the demonstration. Historically, these demonstrations are conducted at sites known to be contaminated with the analytes of interest. The visibility afforded the sites is a valuable way of keeping the local community informed of new technologies. After review of the information available, the site selected for the demonstration is the Green Point Environmental Learning Center (ELC) site, located within the city of Saginaw, Michigan. The Saginaw city-owned, 76-acre Green Point ELC, formerly known as the Green Point Nature Center, is managed by the Shiawassee National Wildlife Refuge. The Refuge is one of over 540 National Wildlife Refuges managed by the U.S. Fish and Wildlife Service, a part of the United States government, in the Department of the Interior. The Green Point ELC offers a variety of environmental educational programs for students of Saginaw and surrounding communities. Furthermore, it offers over 2.5 miles of trails that wind through bottomland hardwood forest, fields, wetlands, and along the banks of the Tittabawassee River. These trails offer opportunities to study various habitats and the wildlife associated with them. Green Point ELC also has a bird watching area, ponds, restored grasslands, and learning center displays. The Green Point ELC is situated within the Tittabawassee River flood plain. The Michigan Department of Environmental Quality (MDEQ) has found higher than normal levels of dioxins in soil and sediment samples taken from the flood plain of the Tittabawassee River. The flood plain is not heavily laden with PCBs; however, low levels of PCBs have been detected in some areas. The MDEQ is taking more samples in the flood plain to determine the extent of contamination. Soil samples taken from areas outside the flood plain have been at normal background levels. The source of the contamination has not been clearly determined and is under investigation. MDEQ is monitoring the level of dioxin in soil and considering the regulatory levels of soil of 50 ppt as a screening level, indicating a need for further study to 1,000 ppt (i.e., 1 ppb) as an action level. 41 ------- To summarize, Green Point ELC was selected as the demonstration site based on the following criteria: • Access and Cooperation of the state and local community—Representatives from MDEQ, EPA Region 5, and local U.S. Fish and Wildlife expressed interest in supporting the demonstration by providing site access for the demonstration. In addition, MDEQ personnel will provide logistical support required for the demonstration and will support a Visitor's Day during the demonstration. • Space Requirements and Feasibility—The demonstration will take place in the parking lot adjacent to the Green Point ELC, not directly on the area of soil and sediment contamination. The site has electrical power and adequate space to house the trailers and mobile labs that will be used for the demonstration. Furthermore, the site is close to an international airport and hospitals and has a sufficient number of lodgings and restaurants. Weather in Michigan can be unpredictable in the month of April; however, all participants will be provided heated containment (a mobile laboratory or hard-sided trailer) so that the weather should not impact the demonstration. Site Diversity—The area encompassing the Green Point site has different levels and types of dioxin contamination in both the soil and sediment needed to evaluate the monitoring and measurement technologies described in Chapter 3. 5.2 Description of Sampling Locations This section provides an overview of the 12 sampling sites and methods of selection. Table 5-1 summarizes each of the locations, what type of sample (soil or sediment) was provided, and the number of samples from each location. Samples provided consisted of either soil or sediment and will be described below based on this distinction. It should be noted that it is not an objective of the demonstration to characterize the concentration of dioxins, furans, and PCBs in material from a specific sampling site. It is, however, necessary to ensure comparability between technology results and the reference laboratory results. This will be accomplished by homogenizing each matrix, such that all sub-samples of a given matrix have consistent contaminant concentrations. As a result, homogenized samples are not necessarily representative of original concentrations at the site. 5.2.1. Soil Sampling Locations This section provides descriptions of each of the soil sampling locations including how the sites became contaminated and approximate dioxin concentrations, as well as the type and concentrations of other major constituents, where known (such as PCBs, PCP, and PAHs). This information was provided by the site owners/sample providers (e.g., EPA, EPA contractors, and MDEQ), and only editorial changes were made byBattelle. 5.2.1.1. Warren County, North Carolina Five different areas of the Warren County PCB Landfill in North Carolina, a site with both PCB and dioxin contamination, were sampled. Dioxin concentrations in the landfill soils range from approximately 475 to 700 pg/g and PCB concentrations are greater than 100 parts per million (ppm). The Warren County PCB Landfill contains soil that was contaminated by the illegal spraying of waste transformer oil containing PCBs from over 210 miles of highway shoulders. Over 30,000 gallons of contaminated oil were disposed of in 14 North Carolina counties. The landfill is located on a 142-acre tract of land. EPA permitted the landfill under the Toxic Substances Control Act. Between September and 42 ------- November 1982, approximately 40,000 cubic yards (equivalent to 60,000 tons) of PCB-contaminated soil were removed and hauled to the new constructed landfill located in Warren County, North Carolina. The landfill is equipped with both polyvinyl chloride and clay caps and liners. It also has a dual leachate collection system. The material in the landfill is solely from the contaminated roadsides. The landfill was never operated as a commercial facility. The remedial action was funded by EPA and the State of North Carolina. The site was deleted from the National Priorities List on March 7, 1986. 5.2.1.2. Tittabawassee River Flood Plain MDEQ sampled the Tittabawassee River flood plain soils from three sites in the flood plain. Two samples were collected from two locations at Imerman Park in Saginaw Township. The first sample was taken near the boat launch, and the second sample was taken in a grassy area near the river bank. Previous analysis from these areas of this park indicated a range of PCDD/F concentrations from 600 to 2,500 pg/g. Total PCBs from these previous measurements were in the low parts-per-trillion range. Two samples were collected from two locations at Freeland Festival Park in Freeland. The first sample was taken above the river bank, and the second sample was taken near a brushy forested area within the park complex. Previous PCDD/F concentrations were from 300 to 3,400 pg/g, and total PCBs were in the low ppt range. The final two samples were collected from Department of Natural Resources (DNR) owned property in Saginaw, which was formerly a farmed area located almost at the end of the Tittabawassee River where it meets the Shiawassee River to form the Saginaw River. Previous PCDD/F concentrations ranged from 450 to 1,150 pg/g. Total PCBs have not been analyzed, but concentrations are expected to be less than 1 ppm. The DNR property is approximately a 10-minute walk from where the demonstration will be conducted at the Green Point ELC. 5.2.1.3 Midland, Michigan Soil samples were collected by MDEQ from various locations in Midland, Michigan. The soil type and nature of dioxin contamination are different in the Midland residential area than it is on the flood plain. The first sample location was soil at the Chippewa Nature Center adjacent to their parking lot in the woods. The soil was a brown sandy loam with an estimated TEQ concentration of less than 10 ppt. The next sample location was in Midland, in the greenbelt between Lynn and Patrick Streets. The soil was dark brown clay loam with an estimated TEQ concentration of 200 ppt. The third location sampled in Midland was near the intersection of Swede and Patrick. Again, the estimated TEQ concentration is 200 ppt. The next soil sample was gathered from a traffic island at the intersection of Saginaw and Bay City Roads. The sample consisted of brown sandy topsoil with an estimated TEQ concentration of 600 ppt. The fifth and final Midland sample location was in the green space between Saginaw Road and sidewalk just south of the Mark Putnam Road intersection. The estimated TEQ concentration is up to 1,000 ppt. 5.2.1.4 WinonaPost The Winona Post site in Winona, Missouri was a Superfund cleanup of a woodtreater facility. Contaminants at the site included pentachlorophenol, dioxin, diesel, and PAHs. Over a period of at least 40 years, these contaminants were apparently deposited into an onsite drainage ditch and sinkhole. Areas of contaminant deposition (approximately 8,500 cubic yards of soils/sludge) were excavated in late 200 I/early 2002. This material was placed into an approximate 2 !/2-acre treatment cell located on facility property. During 2002/2003, material at the treatment cell was treated through addition of amendments (high-ammonia fertilizer and manure) and tilling. Final concentrations achieved in the treatment cell averaged 26 mg/kg for pentachlorophenol and 8,000 to 10,000 for pg/g dioxin equivalents. Samples 43 ------- obtained for this study from this site were obtained from the treatment cell after these concentrations had been achieved. 5.2.7.5 Solutia The chemical production facility at the Solutia site in Nitro, West Virginia, is located along the eastern bank of the Kanawha River, in Putnam County, West Virginia. The site has been used for chemical production since the early 1910s. The initial production facility was developed by the U.S. government for the production of military munitions during the World War I era between 1918 and 1921. The facility was then purchased by a small private chemical company, which began manufacturing chloride, phosphate and phenol compounds at the site. A major chemical manufacturer purchased the facility in 1929 from Rubber Services Company and continued to expand operations at the facility and accelerated its growth in the 1940s. A variety of raw materials have been used at the facility over the years including inorganic compounds, organic solvents, and other organic compounds. The source of the dioxin contamination in the site soils was the manufacture of 2,4,5-T. (Agent Orange is a mixture of chemicals containing equal amounts of two active ingredients: 2, 4-D and 2,4,5-T.) Manufacture of the chemical herbicide began at the site in 1948 and ceased in 1969. The site has a dioxin profile from ppt to low ppb range. No PCBs or PAHs have been identified in the soil. 5.2.2. Sediment Sampling Sites This section provides specific descriptions of each of the sediment sites that includes how the sites became contaminated and approximate dioxin concentrations, as well as the type and concentrations of other major constituents (such as PCBs, PCP, and PAHs). This information was provided from site owners/samples providers (e.g., EPA, EPA contractors, and MDEQ), and only editorial changes were made byBattelle. 5.2.2.1 New York/New Jersey Harbors Dredged materials from the New York and New Jersey Harbors were provided as samples for the demonstration. The U.S. Army Corp of Engineers, New York District, and EPA Region 2 are responsible for managing dredged materials from the New York and New Jersey harbors. Dioxin levels affect the disposal options for dredged material. Dredged materials are naturally occurring bottom sediments, but some in this area have been contaminated with dioxins and other compounds by municipal or industrial wastes or by runoff from terrestrial sources such as urban areas or agricultural lands. 5.2.2.1.1 Newark Bay Surrounded by manufacturing industries, Newark Bay is a highly contaminated area with numerous sources (sewage treatment plants, National Pollutant Discharge Elimination System discharges, and non- point sources). This Bay is downstream from a dioxin Superfund site that contains some of the highest dioxin concentrations yet found in the United States, and also is downstream from a mercury Superfund site. The dioxin concentration in the area sampled for this demonstration is approximately 450 pg/g. Average PCB concentrations range from 300 to 740 ppb. Fine-grained sediments make up 50% to 90%. Average total organic carbon (TOC) is about 4%. 44 ------- 5.2.2.7.2 Raritan Bay Surrounded by industry and residential discharges, Raritan Bay has dioxin contamination in the area, but not to the degree of Newark Bay. No major Superfund sites are located in the vicinity. Dioxin concentration should be significantly less than in Newark Bay. PCB concentrations are around 250 ppb. The fine-grained sediment and TOC values are similar to percentages in Newark Bay. 5.2.2.2 Tittabawassee River Sediments MDEQ sampled six locations in the Tittabawassee River flood plain. The first location is approximately % mile upstream of the Bob Caldwell Boat Launch in Midland, Michigan. The sediments are dark gray, fine sand with some silt. The estimated TEQ concentration is 260 pg/g; however, concentrations as high as 2,100 pg/g TEQ are possible in this area. The second site is on the Tittabawassee River approximately 100 yards downstream from old Smith's Crossing Bridge in Midland, Michigan. The sediment is brown and sandy with organic material. The estimated TEQ concentration is 870 pg/g; but, again, concentrations as high as 2,100 pg/g TEQ are possible in the area. The third site is on Tittabawassee River at the Emerson Park Golfside Boat Launch. The sediment is gray black silty sand, with many leaves and high organic matter. The estimated TEQ concentration is < 5 pg/g. The fourth site is on the Tittabawassee River adjacent to Imerman Park in Saginaw County across from the fishing dock. The sediment is sand with some silt. The estimated TEQ concentration is between 100 and 2,000 pg/g TEQ. The fifth site is on the Tittabawassee River approximately 1 mile downstream of Center Road Boat Launch in Saginaw Township. The sediment consists of sand and gravel with some shells and not much organic matter. The estimated TEQ concentration is between 100 and 1,000 pg/g TEQ. The sixth site also is on the Tittabawassee River across from the Center Road Boat Launch. The sediment is fine sand with high organic matter. The estimated TEQ concentration is 1,000 pg/g TEQ. 5.2.2.3 Saginaw River Sediments MDEQ sampled Saginaw River flood plain sediments with the assistance of staff from the U.S. EPA Great Lakes National Program Office. Samples were collected at six locations in the flood plain area. The first sampling location is in the Saginaw River just downstream of Green Point Island. Samples were collected near the middle of the river in about 21 feet of water. The sample is granular with some organic material. The estimated TEQ concentration is 100 ppt. The next Saginaw River sample was taken upstream of Genesee Bridge on the right side of river. The sample is a brown fine sand from about 15 feet of water. Again, the estimated TEQ concentration is 100 ppt. The third location is in the Saginaw River downstream of the Saginaw wastewater treatment plant in about eight feet of water. The sample is gray silty clay with an unknown TEQ concentration. The fourth location is in the Saginaw River in about eight feet of water. The sample is a black sandy material. The estimated TEQ concentration for this location is again unknown. The fifth location is downstream of a petroleum pipeline crossing upstream of the Detroit and Mackinaw railroad bridge crossing. This location was selected because of its proximity to a former PCB dredging location. The sediment sample consists of dark black silt with some sand. The estimated TEQ concentration is unknown, but PCB concentrations are expected to be high. The sixth and final sampling location is near the mouth of the Saginaw River in about five feet of water. The sediment is a mix of fine black silt and layers of sand and shells. The estimated TEQ concentration for this location is also unknown. 45 ------- 5.2.2.4 Brunswick Wood Preserving Site The Brunswick Wood Preserving Superfund site is located in Glynn County, Georgia, north of the city of Brunswick. The site was originally located in the city of Brunswick, but moved to its present location around 1958. The site is approximately 84 acres and is about two-thirds of a mile long. Burnett Creek, a tidally influenced stream, is located at the western corner of the site. At several points, most, if not all, of the drainage from the site flows into Burnett Creek. The site was first operated by American Creosote Company, which constructed the facility sometime between 1958 and 1960. The site was acquired by Escambia Treating Company in 1969 from Georgia Creosoting Company and the Brunswick Creosoting Company, thought to be the same company. In 1985, a corporate reorganization resulted in the purchase of the facility by the Brunswick Wood Preserving Company, which operated the site until it closed in early 1991. Each of the three major wood-treating operations were carried out at the facility: PCP, creosote, and chromium-copper-arsenic (or CCA). The site was listed on EPA's National Priorities List on April 1, 1997. Sediment samples from the Brunswick Wood Preserving site in Brunswick, Georgia, were collected from six locations on the site, including areas thought to have lower (< 300 pg/g TEQ) and higher (> 10,000 pg/g TEQ) dioxin/furan concentrations. Due to the processes that occurred on this site, the samples also contain varying levels of PAHs and PCP, but should not contain PCBs. Table 5-1.

A SITE demonstration must provide detailed and reliable performance and cost data so that technology users have adequate information to make sound judgments regarding comparability to conventional methods. The demonstration has both primary and secondary objectives. Primary objectives are critical to the technology evaluation and require the use of quantitative results to draw conclusions regarding a technology's performance. Secondary objectives pertain to information that is useful but will not necessarily require the use of quantitative results to draw conclusions regarding a technology's performance. Each report will summarizes the findings of these objectives and provide sufficient documentation for a user to choose an alternative to conventional technology. The primary objectives for the demonstration of the participating technologies are as follows: P1. Determine the accuracy. P2. Determine the precision. P3. Determine the comparability of the technology to EPA standard methods. P4. Determine the method detection limit (MDL). P5. Determine the frequency of false positive (fp) and false negative (fn) results. P 6. Evaluate the impact of matrix effects on technology performance. P7. Estimate costs associated with the operation of the technology. The secondary objectives for the demonstration of the participating technologies are as follows: S1. Document the skills and training required to properly operate the technology. S2. Document health and safety aspects associated with the technology. S3. Document the portability of the technology. S4. Evaluate sample throughput. The objectives for the demonstration were developed based on input from the Dioxin SITE Demonstration Panel members (Appendix A), general user expectations of field measurement technologies, the time available to complete the demonstration, technology capabilities that the 47 ------- developers participating in the demonstration intend to highlight, and the historical experimental components of former SITE Program demonstrations to maintain consistency. 6.2 Overview of Demonstration Samples The goal of the demonstration is to perform a detailed evaluation of the overall performance of the technology for use in contaminated site evaluation. The demonstration objectives will be centered around providing performance data that support action levels for contaminated sites. The Centers for Disease Control's Agency for Toxic Substances and Disease Registry (ATSDR) has established a decision framework for sites that are contaminated with dioxin and dioxin-like compounds.(9) If samples are determined to have dioxin TEQ levels between 50 and 1000 pg/g, the site should be further evaluated; action is recommended for levels above 1,000 pg/g (i.e., 1 ppb) TEQ. A mix of PE samples, environmentally contaminated ("real-world") samples, and extracts will be evaluated that bracket the ATSDR guidance levels. Table 6-1 lists the primary and secondary performance objectives for this demonstration and which sample types will be used in each evaluation. The PE samples will be used to determine the accuracy of the technology and will consist of purchased soil and sediment standard reference materials with certified concentrations of known contaminants and newly-prepared spiked samples. The PE samples will also be used to evaluate precision, comparability, MDL, and false positive/ negative results. Environmentally contaminated samples will be collected from dioxin-contaminated sites around the country (as described in Chapters 4 and 5) and will be used to evaluate the precision, comparability, MDL, false positive/negative results, and matrix effects. Extracts, prepared in toluene, will be used to evaluate precision, MDL, and matrix effects. All samples will be used to evaluate qualitative performance objectives such as technology cost, the required skill level of the operator, health and safety aspects, portability, and sample throughput. Table 6-2 is an outline of the number of each sample type that will be included in the experimental design, and Figure 6-1 illustrates a distribution of the environmental sample concentrations, according to total TEQD/F as determined by the characterization analyses (see Section 4.3). The following sections describe each sample type in greater detail. Table 6-1.

Approximate distribution of environmental sample concentrations. will be utilized to obtain PE samples for use in this demonstration. PE samples will consist of three types of samples: Standard reference materials or certified samples: These will include soil and/or sediment samples with certified concentrations of dioxin, furan, and/or PCBs that are commercially available for purchase. These samples are supplied with a certificate of analysis, including a range of acceptable results based on analytical verification data. Spiked samples: These will include a certified dioxin, furan, PCB, and PAH-clean matrix spiked with known levels of dioxin and/or other contaminants. The spiked samples will be included primarily to allow for more samples to be analyzed across the analytical range of interest, since the 49 ------- availability of a wide-concentration range of certified reference standards is limited. The concentrations of the spiked samples will be verified analytically by the reference laboratory for accuracy to within 10% of the spike concentration. The results for these samples will be compared to the spike concentration (rather than to one analytical verification result) if the measured concentration is within 10% of the spike concentration. These samples will also have a range of acceptable results provided by the supplier, but this range will be based on an arithmetic calculation and will not be based on analytical data. • Blank samples: These samples will be certified free of dioxins (2,3,7,8-TCDD < 0.1 pg/g), furans (2,3,7,8-TCDF < 0.1 pg/g), WHO PCBs (< 10 pg/g), and PAHs, (< 350 ng/g). PE samples will be included at levels bracketing the ATSDR action levels (i.e., < 50 to > 1,000 pg/g TEQ), and will cover a similar concentration range and congener patterns as the environmental samples. 6.2.2 Environmental Samples Prior to the demonstration, samples were collected from 10 sampling locations from around the country and shipped to Battelle. The sampling locations, which are described in Chapter 5, were identified by EPA Regional staff and MDEQ. The EPA and MDEQ staff who identified specific sampling locations were part of the Dioxin SITE Demonstration Panel (Appendix A) and were responsible for arranging for sample collection and providing information about the sites (Chapter 5). Once received at Battelle, the environmental samples were homogenized and characterized for dioxin/furans (EPA Method 1613B), PCBs (LRMS modified EPA Method 1668A), and 18 target PAHs (NOAA method) to establish the basic composition of the samples. Environmental samples were selected for inclusion in the demonstration based on the preliminary characterization data. Because the soil and sediment samples were dried and homogenized, they will essentially be indistinguishable to the developers. As such, the soil and sediment samples will be jointly referred to as "environmental" samples, with no distinction made between soil or sediment other than in Chapter 5 where the sampling locations are described in detail. 6.2.3 Extracts To evaluate the detection and measurement performance of each technology independent of the sample extraction method, soil and sediment samples will be extracted using toluene and soxhlet extraction. These extractions will be performed by AXYS Analytical Services (the reference laboratory, see Chapter 7), consistent with the procedures to extract the demonstration samples. The extracts will represent a 10 g soil/sediment sample extraction and will be reported in pg/mL. Total extract volume per 10 g aliquot will be 300 mL, but the sample extracts will be concentrated and provided to the developers as 10 mL extracts. The extracts will not be processed through any clean-up steps. The extracts will be derived from soil/sediment samples that are also included in the suite of environmental samples, so these samples will be analyzed by the developers starting from both the environmental matrix and the extract. All environmental sample extractions will be prepared in the same solvent (toluene), and the developers will be responsible for any solvent exchange steps. The extract samples will also include toluene-spiked solutions that are not extractions of actual environmental samples. Because adequate homogenization at trace quantities will be difficult to achieve, one set of extract samples will be spiked at low levels (< 1 pg/mL) and used as part of the MDL evaluation. 50 ------- 6.3 Pre-Demonstration Study The best way to predict and prevent problems from occurring during the demonstration is to perform a "dry run" exercise. This was accomplished through a pre-demonstration study. The pre-demonstration samples were sent to all six developers for evaluation in their laboratories, as well as to the reference laboratory. The pre-demonstration study served as a final readiness check for the developer so that modifications could be made to their procedure if warranted by site-specific conditions. It was also a test of the demonstration plan to ensure a well-established process of sampling, compositing, homogenizing, splitting, extract preparation and aliquoting, and shipping of samples to the developers and the reference laboratory. The pre-demonstration study was comprised of 15 samples, including PE samples, environmental samples, and extracts. A distribution of the sample concentrations, as determined by the characterization analyses (see Section 4.3), is presented in Figure 6-2. The samples selected for the pre- demonstration study covered a wide range of concentrations and included a representative of each environmental site that will be analyzed during the demonstration. The pre-demonstration study was conducted in two phases. In Phase 1, the developers were sent six soil/ sediment samples and provided the D/F, PCB, and PAH characterization data with the samples, so that each developer could perform a self-evaluation of their technology's performance. In Phase 2, seven 10000 -, 9000 8000 - | g- 7000 - | ^ 6000 8 1 5000 - c *> o f| 4000 U- Q. S ~ 3000 - 2000 - 1000 C B • B • " ) 2 4 6 8 10 12 14 Sample No. Figure 6-2. Approximate range of pre-demonstration soil/sediment sample concentrations. additional soil/sediment samples and two extracts were sent to the developers for blind evaluation. The reference laboratory analyzed all 15 pre-demonstration samples blindly. Battelle collected the pre- demonstration results from the developers and the reference laboratory, and then returned the developer/ reference laboratory correlated data back to each developer so that the developers could use the HRMS pre-demonstration sample data to refine the performance of their technologies prior to participating in the field demonstration. 51 ------- 6.4 Demonstration Schedule The developers will analyze the demonstration samples in the mobile laboratories or trailers equipped with fume hoods at the demonstration site in Saginaw, Michigan. The schedule for the demonstration is as follows. Developers will begin shipping equipment and supplies to the demonstration site the week of April 19. On Thursday, April 22, the mobile laboratories and trailers will be installed. The developers can begin arriving as early as April 22 and will have access to the demonstration site as soon as the trailers and mobile laboratories are installed and ready for occupancy. The developers can work at the site on April 23, 24, and 25 setting up their oeprations and running their own quality control samples. The demonstration will officially commence on Monday, April 26, with a safety and site-specific training meeting at the auditorium in the Green Point ELC at 8 am. During this meeting, the health and safety plan will be reviewed so that all participants understand the safety requirements for the demonstration. Site health and safety (H&S) personnel, identified in Chapter 10, will be readily accessible throughout the course of the demonstration in case H&S questions arise. During the kick-off meeting, logistics will also be discussed, such as how samples will be distributed and results reported. It is anticipated that the developers will analyze the demonstration samples for 3 to 9 days, depending upon the sample throughput of each technology. Ideally, all 209 samples would be analyzed on-site, but the sample throughout of some of these technologies would require three weeks or more in the field to analyze 209 samples. Consequently, it was decided that the number of samples to be analyzed in the field by each developer would be determined at the developer's discretion. The developers are requested to analyze all 23 extract samples and at least half of the soil/sediment samples (93 samples). If a developer does not complete all 209 analyses in the field, the remaining samples will be shipped to the developer's laboratory at the conclusion of the demonstration activities and results will be due to Battelle at a pre-determined time after leaving the site. The time that the results generated off-site will be due to Battelle will be specified and adhered to by the developer.

The samples will be prepared, homogenized, and split into subsamples according to the processes outlined in Chapter 4. Samples will be labeled with a unique identifier and randomized blind analysis will be performed by the developers. Certified, spiked, uncontaminated (i.e., blank), and environmental samples will be randomly inserted into the testing scheme. Chain-of-custody procedures will be used to transfer samples from Battelle to the developers. Some sample information will be provided when the samples are distributed. All samples that are believed to have at least one D/F or PCB congener greater than 10,000 pg/g will be marked with an asterisk for safety purposes. The sites for the environmental samples will be identified to the reference laboratory for congener pattern recognition. Wako and CAPE Technologies requested that samples be identified as "soil" or "sediment"; none of the other developers wished to have that information supplied. This sample information will be supplied when the first batch of samples are released. 53 ------- Table 6-3 Designations for Generic Data Qualifiers Designation Lb M H Uc Total TEQD/F (Pg/g) <50 50-1,000 > 1,000 not characterized WHO PCB a (Pg/g) < 1,000 1,000-10,000 > 10,000 not characterized PAHsa (ng/g) < 1,000 1,000-10,000 > 10,000 not characterized a Characterized for target list only; indicates approximate value of each target analyte b Includes non-detects c Applies to SRMs only where certified data not available for certain PAHs or PCBs Table 6-4 Distribution of Performance Evaluation Samples Sample Type PE#1 PE#2 PE#3 PE#4 PE#5 PE#6 PE#7 PE#8 PE#9 PE#10 PE#11 PE#12 Generic Data Qualifier D/F L H M M M L L L L L L certified blank PCB L U L H H L L L L H M certified blank PAH U U U U L L L M L L L certified blank Total Number ofPE samples No. of Replicates per Sample 7 4 7 4 4 4 4 4 4 4 4 8 58 54 ------- Table 6-5 Distribution of Environmental Samples Sample Type Environmental Site #1 Warren Co, North Carolina Environmental Site #2 Tittabawassee River (soil), Michigan Environmental Site #3 Newark Bay, New Jersey Environmental Site #4 Raritan Bay , New Jersey Environmental Site #5 Winona, Missouri Environmental Site #6 Tittabawassee River (sediment), Michigan Environmental Site #7 Brunswick, Georgia Environmental Site #8 Saginaw River, Michigan Environmental Site #9 Midland, Michigan Environmental Site #10 Nitro, West Virginia Generic Data Qualifier D/F M H H L M M L M L L L L L H H H L M L L L H M H M M M M L L H H PCB H H H L L L L L L L L L L L M L L L L L L L M M L L L L L H H H PAH L H H L L L L L L L L L L M M M L L L M L H L L H L L L L L L L Total number of environmental samples No. of Replicates per Sample 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 128 55 ------- Table 6-6 Distribution of Extract Samples3 Sample Type Extract* 1 Extract* 2 Extract* 3 Extract* 4 Extract* 5 Generic Data Qualifier D/F L H L M L PCB L L L M H PAH L M L L L Total number of extracts No. of Replicates per Sample 4 4 7 4 4 23 a All developers will analyze the 23 extract samples on-site during the demonstration. Extract samples will be prepared by the reference laboratory in their typical extraction solvent (toluene). Independent technical observers, Battelle staff who are familiar with use of these technologies, will watch the developer analyses as they are being performed to meet the second objectives of the demonstration to understand the operational aspects of the technologies. It is likely that all observers will intermittently observe each technology in operation over the course of the demonstration, but one observer will be assigned primary responsible for each technology. The checklists that will be used to document the observers notes and facilitate the observations are presented in Appendix E. These observations will be summarized and reported in each developer's ITVR. Each developer will have the opportunity to review the observer notes for their technology prior to inclusion in the report. Photo-documentation will supplement written observations recorded by Battelle staff. However, Battelle will not photograph any portion of the developer's technology without approval. The amount and type of hazardous and non-hazardous waste that is generated during the demonstration will be recorded and confirmed by Battelle. All sample by-products produced during testing will be returned to Battelle for quantification and characterization prior to disposal. The results of the demonstration will likely be impacted by fatigue if the developers work more than 12 hours per day, so the developers will be advised to work no more than a 12-hour day for each day of testing (e.g., 7 am - 7 pm). The exact start and end time for each demonstration day will be decided on- site amongst all the participants. It is requested that the developers stay on approximately the same start time, as requests to start and end significantly later than the other participants (for example, working noon to midnight when all of the other participants are working approximately 7 am to 7 pm) will not be granted. The developers will be responsible for operating their own technologies and for providing all equipment and supplies needed for its operation during the demonstration, unless otherwise arranged with Battelle prior to the demonstration. The developers will also be responsible for supplying their own personal protective equipment such as gloves and lab coats. 56 ------- 6.6 Assessment of Primary and Secondary Objectives The term, "dioxin and dioxin-like compounds" groups several hundreds of compounds in a category because these compounds are similar in chemical structure and biological activity. The reference laboratory will measure individual congeners that are the most significant sources of toxicity. The seventeen 2,3,7,8-substituted PCDD/F will be determined by Method 1613B; 12 WHO PCBs will be reported using Method 1668A. The developer technologies will report TEQ, total TEQ or DEQ (dioxin equivalents), but none will report data for individual congeners. As shown in Table 6-7, some technologies will report (1) total TEQD/F(2) total TEQPCB, or (3) total TEQ, including contributions from D/F and PCBs. For the reference laboratory data, congener concentrations will be converted to TEQ and subsequently summed to determine total TEQ, using the TEFs established by WHO in 1998(4) (see Table 1-1). For the reference laboratory data, non-detects will be assigned a TEQ value of zero and 1A of the detection limit. Detection limits will be reported as SDLs (Sample-Specific Detection Limits). SDLs will be determined from 2.5 times the noise in the chromatogram, converted to an area and then to a concentration using the same calculation procedure as for detected peaks. Any value that meets all quantification criteria (>SDL and ratio) will be reported as a concentration. A"J" flag will be applied to any reported value that is between the SDL and the lowest level calibration. The concentration of any detected congener that does not meet all quantification criteria (such as ratio or peak shape) will be reported but given a "K" flag to indicate estimated maximum possible concentration (EMPC). TEQs will be reported in 2 ways to cover the range of possible TEQ values: 1. All ND and EMPC values will be assigned a zero concentration in the TEQ calculation. 2. NDs will be assigned a concentration of one half the SDL. EMPCs will be assigned a value equal to the EMPC. In both cases, any TEQ which has = 10% contribution from J flagged or K flagged data will also be flagged as J or K or both as appropriate. 57 ------- Table 6-7.

However, the similar statistical principles will be applied to the evaluation of each technology, as described below. 6.6.1 Primary Objective PI: Accuracy The determination of accuracy for each technology's measurements will be based on their agreement with the certified or spiked levels of PE samples. For each technology, PE samples containing concentrations from across the analytical range of interest will be analyzed. The technology measurements from the 58 PE samples will be evaluated to determine whether there is a statistically significant difference between the technology measurements and the certified value or spiked level. Percent recovery values relative to the certified or spiked concentrations will also be calculated. Battelle will evaluate whether a statistically significant difference exists between a given technology's results and the reference values by performing a two-tailed, paired, Student's t-test. The null hypothesis will be that the mean difference between the technology results and the certified or spiked value is zero. The PE samples will also be analyzed by the laboratory reference method for confirmation of certified and spiked values. To evaluate accuracy, the average of replicate results from the field technology measurement will be compared to the certified or spiked value of the PE samples to calculate percent recovery. The equation to be used will be: R= C /Co x 100 58 ------- where C is the average concentration value calculated from the technology replicate measurements and CR is the certified value. For the spiked samples, if the reference laboratory's average measured value is within 10% of the spiked concentration value, the spiked concentration value will be used as the certified value. If the average measured value by the reference laboratory is > 10% different, the reference laboratory's average measured value will be the certified value. 6.6.2 Primary Objective P2: Precision A technology's precision refers to its reproducibility. Higher precision leads to less uncertainty in the results. To evaluate each technology's precision, all samples (including PE, environmental and extract samples) will be analyzed in at least quadruplicate. Seven replicates of three different samples will also be analyzed to evaluate method detection limits. Replication is necessary because precision will be evaluated at both low and high concentration levels, and across different matrices. The statistic used to evaluate precision is RSD. The equation used to calculate standard deviation (SD) between replicate measurements will be: SD = -V - C) k=l 1/2 where SD is the standard deviation and C is the average measurement. The equation used to calculate RSD between replicate measurements will be: RSD = SD x 100 C Low RSD values indicate high precision. For a given set of replicate samples, the RSD of a given technology's results will be compared with that of the laboratory reference method's results to determine whether the reference method is more precise than the technology or vice versa for a particular sample set. 6.6.3 Primary ObjectiveP3: Comparability A third primary performance objective is comparability, i.e., the degree of agreement between each technology and reference laboratory results. Battelle maximized data comparability by using the homogenization procedures and applying criteria for acceptable results prior to a sample being included in the demonstration, as described in Section 4.2. For comparability, Battelle will evaluate whether a statistically significant difference exists between the measurements provided by a given technology and the laboratory reference method by performing a two- tailed, paired, Student's t-test. If the data are found to be non-normally distributed, a nonparametric Wilcoxon signed-rank test will be performed to determine if the two sets of results are statistically the same or different. Technology results will also be compared to the corresponding reference laboratory by calculating a relative percent difference (RPD) for the average of each paired and replicate measurement. The equation for RPD is as follows: 59 ------- (MR - MD) RPD = —i '-— average(Mr, MD) where MR is the reference laboratory measurement and MD is the developer measurement. RPD values less than 25% will indicate good agreement between the two measurements. Because the absolute value will not taken, negative RPD values can be obtained (which would indicate that the technology measurements were less than the reference laboratory measurements). As such, the median RPD value will be calculated (rather than the average RPD where the negative and positive values would be neutralized) to provide a summary calculation of comparability between each technology's results and reference laboratory measurements. As described in Section 1.3, the reference laboratory concentration data will be converted to TEQ using the WHO TEF values. TEQs will be calculated by the developer technologies in unique ways that may or may not be directly comparable to the HRMS total TEQD/F, total TEQPCB, or total TEQ results, depending upon the developer calibration techniques (i.e., calibration to a single congener) and/or the functionality of the developer's technology and its relative responsiveness to the WHO-established TEFs. The correlation of the developer results with the HRMS results will be evaluated and it will be noted if the developer technology does or does not track the HRMS results on a relative scale. Assessments will be made as to how well the developer results tracked the HRMS results in light of possible confounding factors such as the sample containing other Ah Receptor binding compounds, cross-reactive compounds, or extremely high concentrations of particular analytes. 6.6.4 Primary Objective P4: Method Detection Limit A fourth primary performance objective is to determine the MDL for each technology. To determine the MDLs, the developer will analyze seven aliquots of two low-level PE soil samples and seven aliquots of a low-level spiked extract. Battelle will use these data to calculate an MDL for each technology. The concentration of the samples will be dependent on the detection capability of each technology, but will ideally be three to five times the reporting limit for each technology. The MDL calculation procedure to be followed is described in 40 CFR Part 136, Appendix B, Revision 1.11. This procedure is based on an assumption that the replicates are homogeneous enough to allow proper measurement of the analytical precision, which will be true for the demonstration because of the homogenization and sample preparation procedures that will be followed. Battelle will use the Student's t-value and standard deviation to calculate the MDL for each technology in soil and sediment as shown in the following equation: MDL = t(n.u_0.99)(SD) where t(n_u_^99) = Student's t-value appropriate for a 99 percent confidence level and a standard deviation estimate with n-1 degrees of freedom. 6.6.5 Primary Objective P5: False Positive/False Negative Results Battelle will investigate the tendency for each technology to return fp results, that is, results reported above the reporting limits for the field technology but below the reporting limits of the reference laboratory. The frequency of fp results will be reported as a fraction of results available for fp analysis. Similarly, the frequency of fn results will also be examined. For this purpose, Battelle will evaluate 60 ------- results for samples reported as having concentrations above the reporting limits of the reference laboratory method to identify cases of the reference laboratory reporting detections and a technology reporting non-detects. As with the analysis of false positives, the statistic analyzed for each technology will be the percentage of fn out of all samples reported as detections by the laboratory method. A point of clarification regarding the "reporting limits" of a technology and the "method detection limits" as described in Section 6.6.4. The reporting limits to be used in this evaluation will be the value designated by each technology developer and the reference laboratory, as the lowest level to be reported for each sample. This will vary from developer to developer. The MDL determination will include an evaluation of the stated reporting limits, with a sample 3 to 5 times the reporting limit of each technology analyzed 7 times, to assess the closeness of the technology's calculated MDL to the reporting limits used in the demonstration. 6.6.6 Primary Objective P6: Matrix Effects The likelihood of matrix-dependent effects on performance will be investigated by evaluating the data sets in multiple ways. This will include evaluation of results in the following ways: samples from the ten different environmental sampling locations individually and as a group to determine if performance was different for environmental samples versus PE samples; grouping the data by matrix (i.e., soil, sediment, extract); evaluating samples with similar congener patterns (e.g., samples with high hepta- and octa- dioxins); assessing the performance with samples containing high levels of contaminants other than dioxins (e.g., PCBs or PAHs); and evaluation of in-field versus laboratory conducted measurements (where appropriate). These evaluations will also include looking at the performance of the technology for the samples which were analyzed both as extracts and as environmental soil/sediment samples. Differences in results provided for the soil/sediment samples and their associated extract samples may indicate a matrix or homogeneity issue if the comparison of the developer and HRMS results for the extract samples are in better agreement than for the analysis of the associated soil/sediment sample. If the soil/sediment sample HRMS and developer results are highly correlated, but the comparative results for the extracts are not, it may indicate that the toluene extract was not compatible with the developer's procedure if toluene is not their extraction solvent. 6.6.7 Primary Objective P7: Technology Costs Since conventional laboratory-based analytical methods for measuring dioxins are relatively costly, the cost of each field technology is an important evaluation factor. With input from each technology developer, Battelle will document the full cost of each technology and compare those costs to typical and actual costs for D/F and PCB analytical methods. At a minimum, cost inputs will include equipment, consumable materials, mobilization and demobilization, and labor. Battelle will document what equipment was provided by the developer and what was provided by Battelle. 6.6.8 Secondary Objective SI: Skills and Training Required to Properly Operate the Technology As described in Section 6.5, Battelle observers will be assigned to each of the technologies. These notes and observations will determine the number and skill-level of the operators. The observers will also determine the type of background and training required to properly operate the technology. The evaluation of this secondary objective will also include how user-friendly the technologies are. The developers will have the opportunity to review and comment on the observers notes before the observations are incorporated into the report to ensure accuracy. 61 ------- 6.6.9 Secondary Objective S2: Document Health and Safety Aspects Associated with the Technology Because dioxins are a class of toxic compounds, it is important to understand the health and safety aspects associated with each technology. This will include health and safety issues when operating the technology as well as the amount and type of hazardous and non-hazardous waste generated by the technology. The outcomes from this evaluation will be based on the observer notes. 6.6.10 Secondary Objective S3: Document the Portability of the Technology This evaluation will document if the technology can be readily transported to the field and how easy the technology was to operate in the field. The Battelle observers will be responsible for the collection and reporting of this information. 6.6.11 Secondary Objective S4: Evaluate Sample Throughput Because HRMS methods are time consuming, it will be important to note the sample throughput (i.e., number of samples that can be processed in a typical work day). This secondary objective will be evaluated based on the observer notes, which will make particular note of the time limiting steps of the procedures, as well as the documentation of sample custodianship that will be recorded on the COC/results forms (Appendix D). The number of operators involved in the sample analyses will also be discussed. 6.7 Schedule of Events Table 6-8 is a summary of events since the award of the contract to perform this demonstration.

The reference laboratory has provided the method performance information that is presented in this chapter. 7.1 Reference Method Selection Three EPA analytical methods for the quantification of dioxins and furans were available: Method 1613B, Method 8290, and Method 8280. Method 8280 is a LRMS method that does not have adequate sensitivity (i.e., the detection limits reported by the developers are less than that of the LRMS method). Methods 1613B and 8290 are both high resolution mass spectrometric methods. Method 1613B includes more labeled internal standards which, therefore, affords more accurate congener quantification. Therefore, it was determined that Method 1613B best met the needs of the demonstration and it was selected as the dioxin/furan reference method. The Dioxin SITE Demonstration Panel (Appendix A) proposed that an equal amount of reference data be generated to determine the PCB contribution to the TEQ, since risk assessment is often times based on TEQ values that are not class specific. As such, the complimentary HRMS method for PCB TEQ determinations, Method 1668A, was selected as the reference method for PCBs. 7.2 Reference Laboratory Selection Battelle generated a list often prospective laboratories, based on conversations with EPA Regional staff who routinely use dioxin laboratories, personal experiences, and recommendations from the Dioxin SITE Demonstration Panel. The ten laboratories were contacted by Battelle and were sent a questionnaire to complete (see Appendix F). The 14 questions were geared towards understanding the capabilities of the laboratories, their experience with analyzing dioxin samples for EPA, and their ability to meet the needs of this demonstration. The responses from the questionnaires were studied and two laboratories were selected for the next phase of the selection process. The two laboratories were sent three blind audit samples and were audited by two auditors from Battelle. The day-long audit at each laboratory included a technical systems audit and a quality systems audit. At each laboratory, the audit consisted of a short opening conference, a full day of observation of laboratory procedures, records, interviews with laboratory staff, and a brief closing meeting. Auditors submitted follow-up questions to each laboratory to address gaps in the observations. This was done to ensure consistency in the process. 64 ------- Criteria for final selection were based on the observations of the auditors, the performance on the audit samples, and cost. From this process, it was determined that AXYS Analytical Services (Sidney, British Columbia, Canada) would best meet the needs of this demonstration, so AXYS was selected as the reference laboratory for this demonstration. The statement of work that was provided to AXYS to perform the reference methods is provided in Appendix G. 7.3 Reference Laboratory Sample Preparation and Analytical Methods The purpose of this section is to describe the reference methods that will be used in the demonstration sample analyses. Both Method 1613B(6) and Method 1668A(7) allow for method modifications, as long as the modifications are documented and the requirements for method performance (i.e., performance specifications for quality control samples) can be met. The following sections briefly describe the methods and the modifications to the methods that AXYS performs. For brevity, the entire methods are not reproduced in this document, but the applicable sections where AXYS will perform modifications have been cited for convenient reference. 7.3.1 Dioxin/Furan An alysis All procedures are carried out according to protocols as described in AXYS Summary Method Doc MSU-018 Rev 2 18-Mar-2004 (AXYS detailed SOP MLA-017 Rev 9 May-2004), which is based on EPA Method 1613B, with the modifications summarized below. Briefly, samples are spiked with a suite of isotopically labeled surrogate standards prior to analysis, solvent extracted, and cleaned up through a series of chromatographic columns that may include gel permeation, silica, Florisil, carbon/Celite, and alumina columns. The extract is concentrated and spiked with an isotopically labeled (internal) standard. Analysis is performed using a high-resolution mass spectrometer coupled to a high-resolution gas chromatograph equipped with a DB-5 capillary chromatography column (60 m, 0.25 mm i.d., 0.1 |im film thickness). A second column, DB-225 (30 m, 0.25 mm i.d., 0.15 |im film thickness), is used for confirmation of 2,3,7,8-TCDF identification. The following is a summary of AXYS's 1613B method modifications. The italicized text is the portion of the method that is being modified, followed by the AXYS modification. Section 2.1.2 The labeled compounds are spiked into a sample containing 10 g (dry weight) of solids. Samples containing multiple phases are pressure filtered and any aqueous liquid is discarded. Coarse solids are ground or homogenized. Any non-aqueous liquid from multi-phase samples is combined with the solids and extracted in an SDS extractor. The extract is concentrated for cleanup. Modification: Non-aqueous liquid from the multiphase sample is combined with the solid phase and extracted by Dean Stark soxhlet. Section 7.2.1: Sodium sulfate, reagent grade, granular, anhydrous (Baker 3375, or equivalent), rinsed with methylene chloride (20 mL/g), baked at 400 "Cfor one hour minimum, cooled in a dessicator, and stored in a pre-cleaned glass bottle with screw-cap that prevents moisture from entering. If, after heating, the sodium sulfate develops a noticeable grayish cast (due to the presence of carbon in the crystal matrix), that batch of reagent is not suitable for use and should be discarded. Extraction with methylene chloride (as opposed to simple rinsing) and baking at a lower temperature may produce sodium sulfate that is suitable for use. 65 ------- Modification: Anhydrous sodium sulphate (NajSO^ is purchased in powder form (not granular) and is baked overnight prior to use. There is no solvent rinse with dichloromethane. Section 7.10: From stock solutions, or from pur chased mixtures, prepare this solution to contain the labeled compounds in nonane at the concentrations shown in Table 3. Note: See Appendix H for Table 3. All tables in Appendix H are reproduced verbatim from the method. Modification: The concentration of the labeled compound spiking solution is 100 ng/mL (except for OCDD which is 200 ng/mL), the concentration of the labeled clean-up standard solution is 10 ng/mL and the concentration of the labeled injection internal standard solution is 100 ng/mL. The spiking volume for all these labeled standard solutions is 20 |iL. The resulting concentrations in the final extracts are as specified in the method. Section 7.11: Prepare Cl -2,3,7,8-TCDD in nonane at the concentration shown in Table 3. The cleanup standard is added to all extracts prior to cleanup to measure the efficiency of the cleanup process. Modification: The concentration of the clean-up standard spiking solution is 10 ng/mL and the sample spiking volume is 20 |iL. The resulting concentrations in the final extracts are as specified in the method. Sections 7.13 Combine the solutions in Sections 7.9 through 7.12 to produce the five calibration solutions shown in Table 4 in nonane. 14.0 HRGC/HRMS Analysis 15.0 System and Laboratory Performance. Note: See Appendix H for Table 4. Modification: An additional lower level calibration solution, 0.2 times the concentration of CS1, is prepared and included in the initial calibration series. Initial calibration is based on a six-point series. Section 7.14 Precision and Recovery (PAR) Standard-Used for determination of initial (Section 9.2) and ongoing (Section 15.5) precision and recovery. Dilute 10 pL of the precision and recovery standard (Section 7.9.1 or 7.9.2) to 2.0 mL with acetone for each sample matrix for each sample batch. One mL each are required for the blank and OPR with each matrix in each batch. Modification: The concentrations of the PAR spiking solutions are 0.2/1.0/2.0 ng/mL for tetra/penta, hexa, and hepta/octa, respectively, and the spiking volume is 1 mL. The resulting final concentration in the extracts are as specified in the method. Section 11.5 Preparation of Samples Containing Greater Than 1% Solids. Modification: Aqueous samples containing > 1% visible solids are prepared and extracted using the same procedure as samples containing < 1% visible solids. This involves extracting the solids by soxhlet and the filtrate by separatory funnel extraction and combining the extract from the two phases. Section 12 Extraction procedures include separatory funnel (Section 12.1) and solid phase (Section 12.2) for aqueous liquids; Soxhlet/Dean-Stark (Section 12.3) for solids, filters, and SPE disks; and Soxhlet extraction (Section 12.4.1) and HCl digestion (Section 12.4.2) for tissues. Acid/base back-extraction (Section 12.5) is used for initial cleanup of extracts. Macro-concentration procedures include rotary evaporation (Section 12.6.1), heating mantle (Section 12.6.2), and Kuderna-Danish (K-D) evaporation (Section 12.6.3). Microconcentration uses nitrogen blowdown (Section 12.7). Modification: Samples with sufficiently low moisture content may be mixed with Na2SO4 and extracted using the regular soxhlet apparatus in 80:20 toluene:acetone. Section 12.4 Add 30-40 g of powdered anhydrous sodium sulfate to each of the beakers (Section 11.8.4) and mix thoroughly. Cover the beakers with aluminum foil and allow to equilibrate for 12-24 hours. 66 ------- Modification: The equilibration time for the sodium sulphate drying step is that required to produce a dry, free flowing powder (minimum thirty minutes). This may be less than the 12-hour minimum specified. Section 12.5.1 Spike 1.0 mL of the cleanup standard (Section 7.11) into the separatory funnels containing the sample and QC extracts from Section 12.1.4.1, 12.3.9.1.3, or 12.3.9.2. Modification: Samples are spiked with cleanup standard right after extraction and before reduction; not spiked into the separatory funnels containing the extracts prior to the acid/base wash. Section 12.6.1.1 Assemble the rotary evaporator according to manufacturer's instructions, and warm the water bath to 45 °C. On a daily basis, preclean the rotary evaporator by concentrating 100 mL of clean extraction solvent through the system. Archive both the concentrated solvent and the solvent in the catch flask for a contamination check if necessary. Between samples, three 2-3 mL aliquots of solvent should be rinsed down the feed tube into a waste beaker. Modification: Rotary evaporator baths are maintained at 35°C. Mimic proofs are collected instead of collecting proofs each day and archiving. Section 13.0 Extract Cleanup. Modification: Extracts may be cleaned up on silica, alumina, and carbon chromatographic columns using a Fluid Management System automated cleanup system. Sections 14.0 HRGC/HRMS Analysis 15.0 System and Laboratory Performance. ,16.0 Qualitative Determination, Table 8, Table 9: Note: See Appendix H for Tables 8 and 9. Modification: M/Z channels 354/356 and 366/368 are used to confirm and quantify the native and surrogate penta-substituted dioxins, respectively; this change from the method's specification is made in the instrument method in order to avoid a persistent interference in the 356/358 and 368/370 M/Z channels. The theoretical ratio for the P5CDD M/M+2 ions is 0.61; therefore, the acceptance range is 0.52 -0.70. Section 17.0 Quantitative Determination Modification: Conct - the concentrations of target analytes, and the labeled compound concentrations and recoveries, are calculated using the equations below. These procedures are equivalent to those described in the method, but are more direct. Cone, = —-X ^— x- ASI RRFita Mx where Ai = summed areas of the primary and secondary m/z channels for the analyte peak of interest (compound/) Asi = summed areas of the primary and secondary m/z channels for the labeled surrogate peak used to quantify /') Mx = mass of sample taken for analysis Msi = mass of labeled surrogate (compound si) added to sample as calculated by the concentration of standard spiked (pg/mL) multiplied by the volume spiked (mL) RRFisi = mean relative response factor of/' to si from the six-point calibration range and defined individually as: 67 ------- ^L M™ = 4* Msl Concentrations of surrogate standards are calculated using the following equation:and, the percent Cone = —— > recoveries of the surrogate standards are calculated using the following equation: %Recovery =—^x M" x—!— xlOO A. where Ars and Asi are the summed peak areas (from the primary and secondary m/z channels) of recovery standard and labeled surrogate added to the sample Mrs and M^ are the masses of recovery standard and labeled surrogate added to the sample RRFsirs is the mean relative response factor of the labeled surrogate to the recovery standard as determined by the six-point calibration range and defined individually as: A. M Section 17.5 If the selected ion current profile area at either quantitation m/z for any compound exceeds the calibration range of the system, a smaller sample aliquot is extracted. Modification: Extracts may be diluted with solvent and reanalyzed by GC/MS isotope-dilution to bring the instrumental response to within the linear range of the instrument. For very high-level samples where a smaller sample aliquot may not be representative, extracts may be diluted and respiked with labeled quantification standards and reanalyzed by GC/MS to bring the instrumental response analytes within range. Final results may be recovery corrected using the mean recovery of labeled quantification standards. 7.3.1.1 Effects of these Modifications on Method Performance It should be noted that the performance of this method including these modifications will be verified during the in-process audit of the reference laboratory and by the laboratory's performance on QC samples. These checks will confirm that the above-listed modifications will not negatively affect the accuracy or precision of the reference laboratory results. 7.3.2 PCB Analysis The method is carried out in accordance with the protocols described in AXYS Summary Method Doc MSU-020 Rev 3 24-Mar-2004 (AXYS detailed SOP MLA-010 Rev 5 Sep-2003), which is based on EPA Method 166 8A, with changes through August 20, 2003, incorporating the AXYS modifications described below. Details of all procedures are documented in AXYS method MLA-010, Analytical Method for 68 ------- Determination of 209 PCB Congeners by EPA Method 1668A. Briefly, samples are spiked with isotopically labeled surrogate standards, solvent extracted and cleaned up on a series of chromatographic columns which may include silica, Florisil, alumina, carbon/Celite and gel permeation columns. The final extract is spiked with isotopically labeled recovery (internal) standards prior to instrumental analysis. Analysis of the extract is performed on an HRMS coupled to a HRGC equipped with a SPB-Octyl chromatography column (30 m, 0.25 mm i.d., 0.25 |im film thickness). Resolution of the PCB 156/157 coelution may be achieved by high resolution GC/MS using a DB-1 chromatography column (30 m, 0.25 mm id, 0.25 |im film thickness). Where required to eliminate interferences, extracts maybe cleaned up by carbon columning to isolate the toxic PCBs of interest; analysis may then be conducted using the DB-1 column as the primary GC column rather than the SPB Octyl column. The following is a summary of AXYS's 1668A method modifications. The italicized text is the portion of the method that is being modified, followed by the AXYS modification. Section 4.2.1 Glassware should be rinsed with solvent and washed with a detergent solution as soon after use as is practical. Sonication of glassware containing a detergent solution for approximately 30 seconds may aid in cleaning. Glassware with removable parts, particularly separatory funnels withfluoropolymer stopcocks, must be disassembled prior to detergent washing. 4.2.2 After deter gent washing, glassware should be rinsed immediately; first with methanol, then with hot tap water. The tap water rinse is followed by another methanol rinse, then acetone, and then methylene chloride. Modification: The protocol for washing reusable glassware includes a detergent wash, water rinse and baking at 325°C for 8 hours. Immediately prior to use, glassware is solvent rinsed with toluene and hexane. Section 4.7 Cleanup oftissue-The natural lipid content of tissue can interfere in the analysis of tissue samples for the CBs. The lipid contents of different species and portions of tissue can vary widely. Lipids are soluble to varying degrees in various organic solvents and may be present in sufficient quantity to overwhelm the column chromatographic cleanup procedures used for cleanup of sample extracts. Lipids must be removed by the anthropogenic isolation column procedure in Section 13.6, followed by the gel permeation chromatography procedure in Section 13.2. Florisil (Section 13.7) is recommended as an additional cleanup step. Modification: The first cleanup column for tissue extracts is a gravity gel permeation column (SX-3 Biobeads). An anthropogenic isolation column 7.5.3 is not used. Section 6.5.1 Pyrex glass wool-Solvent-extracted using a Soxhlet or Soxhlet/Dean-Stark extractor for 3 hours minimum Modification: Glass wool is cleaned by rinsing twice with toluene and twice with hexane. Section 7.12 Labeled Toxics/LOC/window-defining standard spiking solution-This solution is spiked into each sample (Section 9.3) and into the IPR (Section 9.2.1), OPR (Section 15.5), and blank (Section 9.5) to measure recovery. Dilute the Labeled Toxics/LOC/window-defining stock solution (Section 7.9.1) with acetone to produce a concentration of the labeled compounds at 2 ng/mL, as shown in Table 3. When 1 mL of this solution is spiked into an IPR, OPR, blank, or sample and concentrated to a final extract volume of 20 FL, the concentration in the final extract volume will be 100 ng/mL (100 pg/FL). Prepare only the amount necessary for each reference matrix with each sample batch. 7.13 Labeled cleanup standard spiking solution-This solution is spiked into each extract prior to cleanup to measure the efficiency of the cleanup process. Dilute the Labeled cleanup standard stock solution (Section 7.9.2) in methylene chloride to produce a concentration of the cleanup standards at 2 ng/mL, as shown in Table 3. When 1 mL of this solution is spiked into a sample extract and concentrated to a final 69 ------- volume of 20 juL,the concentration in the final volume will be 100 ng/mL (100pg/juL). 9.0 Quality assurance/quality control 11.0 Sample preparation Note: See Appendix H for Table 3.All tables in Appendix H are reproduced verbatim from the method. Modification: The concentration of the labeled toxics/LOC and the cleanup standard spiking solutions is 100 ng/mL and the sample spiking volume is 20 |iL. The resulting final concentrations in the extracts are as specified in the method. Section 7.14 Labeled injection internal standard spiking solution-This solution is added to each concentrated extract prior to injection into the HRGC/HRMS. Dilute the Labeled injection internal standard stock solution (Section 7.9.3) in nonane to produce a concentration of the injection internal standards at 1000 ng/mL, as shown in Table 3. When 2 //Z of this solution is spiked into a 20 //Z extract, the concentration of each injection internal standard will be nominally 100 ng/mL (100 pg/pL). Note: The addition of 2 pL of the Labeled injection internal standard spiking solution to a 20 pL final extract has the effect of diluting the concentration of the components in the extract by 10%. Provided all calibration solutions and all extracts undergo this dilution as a result of adding the Labeled injection internal standard spiking solution, the effect of the 10% solution is compensated, and correction for this dilution should not be made. Modification: Concentration of the labeled injection internal standard spiking solution (recovery standard) is modified so that a volume of 5 |iL is added. The resulting amount of standard added to the final extract is the same as specified in the method. The solution is spiked into a 15-|iL extract volume for a final extract volume of 20 |iL. Section 7.2.1 Solution drying-Sodium sulfate, reagent grade, granular, anhydrous (Baker 33 75, or equivalent), rinsed with methylene chloride (20 mL/g), baked at 400 °Cfor 1 hour minimum, cooled in a desiccator, and stored in a pre-cleaned glass bottle with screw-cap that prevents moisture from entering. If, after heating, the sodium sulfate develops a noticeable grayish cast (due to the presence of carbon). Modification: Powdered, not granular, sodium sulphate is baked at 325°C for 8 hours rather than at 600°Cfor24hrs. Section 7.5.1 Activated silica gel-100-200 mesh, Supelco 1-3651 (or equivalent), rinsedwith methylene chloride, baked at 180 °Cfor a minimum ofl hour, cooled in a desiccator, and stored in aprecleaned glass bottle with screw-cap that prevents moisture from entering. Modification: Silica is activated by baking at 450°C in a muffle oven for at least 8 hours. Section 7.5.4.1.1 Fill a clean 1- to 2-L bottle 1/2 to 2/3 full with Florisil and place in an oven at 130-150 °C for a minimum of three days to activate the Florisil. Modification: Florisil is baked at 450°C in a muffle oven for at least 8 hours, then deactivated with water to 2.1% deactivation. Section 11.5.6 Decant excess water. If necessary to remove water, filter the sample through a glass-fiber filter and discard the aqueous liquid. Modification: Unless requested by the client, the aqueous portion after filtration of aqueous samples with > 1% solids is not discarded but is extracted. Section 11.5 Preparation of samples containing greater than one percent solids 11.5.2 Spike 1.0 mL of the Labeled Toxics/LOC/window-defining standard spiking solution (Section 7.12) into the sample. 12.3 Soxhlet/Dean-Stark extraction of samples containing particles. Modification: Solid samples are dried by mixing with anhydrous sodium sulphate. The dried solid is extracted using a soxhlet extraction apparatus. The surrogate spike is incorporated after the drying step. The extracting solvent for solids is dichloromethane. 70 ------- Section 11.8 Fish and other tissues-Prior to processing tissue samples, the laboratory must determine the exact tissue to be analyzed. Common requests for analysis offish tissue include whole fish-skin on, whole fish-skin removed, edible fish fillets (filleted in the field or by the laboratory), specific organs, and other portions. Once the appropriate tissue has been determined, the sample must be homogenized. 12.4 Soxhlet extraction of tissue Modification: The surrogate spike is incorporated into the sample after the drying step to eliminate the possibility of disproportional loss of volatile labeled and target compounds. Section 12.4.2 Assemble and pre-extract the Soxhlet apparatus per Sections 12.3.1-12.3.4, exceptuse the methylene chloride :hexane (1:1) mixture for the pre-extraction and rinsing and omit the quartz sand. Modification: The pre-cleaning of the soxhlet apparatus is carried out using toluene instead of dichloromethane. Section 12.4.9 Percent lipid determination-The lipid content is determined by extraction of tissue with the same solvent system (methylene chloride:hexane) that was used in EPA's National Dioxin Study (Reference 16) so that lipid contents are consistent with that study. Modification: Lipid analysis is carried out by sub-sampling two 2-g portions of the extract from a total 30-g extract weight. The cleanup standard is spiked into the extract after soxhlet extraction and before any lipid analysis or rotary evaporation is done. Section 12.6.1.1: Assemble the rotary evaporator according to manufacturer's instructions, and warm the water bath to 45 °C. On a daily basis, pre-clean the rotary evaporator by concentrating 100 mL of clean extraction solvent through the system. Archive both the concentrated solvent and the solvent in the catch flask for a contamination check if necessary. Between samples, three 2- to 3-mL aliquots of solvent should be rinsed down the feed tube into a waste beaker. Modification: Rotary evaporation is done at 30 deg. C. Daily cleaning of the rotary evaporators include dismantling the vapor tube, sonicating the vapor tube for 20 minutes in toluene, and soaking the vapor tube sheath and locking caps in soapy water overnight. The vapor tube is rinsed with hexane and the vapor tube sheath and locking cap are rinsed with water, methanol, and hexane prior to air drying and assembly. Mimic proofs are run periodically but are not archived daily. Section 12.7.4 When the volume of the liquid is approximately 100 fjL, add 2 to 3 mL of the desired solvent (methylene chloride for GPC andHPLC, or hexane for the other cleanups) and continue concentration to approximately 100 FL. Repeat the addition of solvent and concentrate once more. Modification; Before Florisil or alumina cleanup procedures, a solvent exchange is done by reducing under nitrogen to 300 uL and bulking up to 1 mL in hexane. If toluene is present the extract is reduced to 50 uL under nitrogen and bulked up to 1 mL. Section 12.7.7 If the extract is to be concentrated for injection into the GC/MS (Section 14), qantitatively transfer the extract to a 0.3-mL conical vial for final concentration, rinsing the larger vial with hexane and adding the rinse to the conical vial. Reduce the volume to approximately 100 pL. Add 20 pL of nonane to the vial, and evaporate the solvent to the level of the nonane. Seal the vial and label with the sample number. Store in the dark at room temperature until ready for GC/MS analysis. If GC/MS analysis will not be performed on the same day, store the vial at < -10 °C. Modification: Toluene (1 mL) is added to the eluate from the final column prior to rotary evaporation and nitrogen blow down concentration steps. Section 13.1.1 Gel permeation chromatography (Section 13.2) removes high molecular weight interferences that cause GC column performance to degrade. It should be used for all soil and sediment 71 ------- extracts. It may be used for water extracts that are expected to contain high molecular weight organic compounds (e.g., polymeric materials, humic acids). It should also be used for tissue extracts after initial cleanup on the anthropogenic isolation column (Section 13.6). Modification: GPC chromatography, by a gravity column, is routinely used only for tissue extracts. The GPC cleanup is optional for all other matrices. Section 13.3.1 Place a glass-wool plug in a 15-mm ID chromatography column (Section 6.7.4.2). Pack the column bottom to top with: 1 g silica gel (Section 7.5.1.1), 4 g basic silica gel (Section 7.5.1.3), 1 g silica gel, 8 g acid silica gel (Section 7.5.1.2), 2 g silica gel, and 4 g granular anhydrous sodium sulfate (Section 7.2.1). Tap the column to settle the adsorbents. Modification: Routine layered silica column is as follows: 0.5 g neutral silica, 2 g 28% basic silica, 0.5 g neutral silica, 4 g 44% acidic silica, 4 g 22% acidic silica, 1 g neutral silica. Section 13.3.4 Rinse the receiver twice with 1-mL portions ofhexane, and apply separately to the column. Elute the CBs with 25 mL ofhexane and collect the eluate. Modification: The sample is loaded onto the column followed by 2-3 rinses of a least 1 mL, and eluted with 100 mL ofhexane. Section 14.2 Add 2 //Z of the Labeled injection internal standard spiking solution (Section 7.14) to the 20 jiL sample extract immediately prior to injection to minimize the possibility of loss by evaporation, adsorption, or reaction. If an extract is to be reanalyzed and evaporation has occurred, do not add more Labeled injection internal standard spiking solution. Rather, bring the extract back to its previous volume (e.g., 19 jiL) with pure nonane (18 pL if 2 pL injections are used). Modification: The volume of labeled injection internal standard (recovery standard) added to the extract is 5 |iL, for a final extract volume of 20 |iL. Hexane rather than nonane is used as the solvent to bring extract back to volume for reanalysis or to dilute extracts. Section 17.5 If the selected ion current profile area at either quantitation m/zfor any congener exceeds the calibration range of the system, dilute the sample extract by the factor necessary to bring the concentration within the calibration range, adjust the concentration of the Labeled injection internal standard to 100 pg/pL in the extract, and analyze an aliquot of this diluted extract. If the CBs cannot be measured reliably by isotope dilution, dilute and analyze an aqueous sample or analyze a smaller portion of a soil, tissue, or mixed-phase sample. Adjust the CB congener concentrations, detection limits, and minimum levels to account for the dilution. Modification: Extracts are diluted with hexane. The concentration of the labeled injection internal (recovery) standard is not readjusted to 100 pg/uL when dilutions are performed. Table 6, page 92: Note: See Appendix H for Table 6. Modification: The acceptance ranges for the labeled compounds dichlorobiphenyls (PCBs 4L and 15L) in OPRs, IPRs and samples have been lowered to 15% in recognition of the higher volatility of these compounds. This is a project-specific change to Sections 4.2 and 10.0 of SOP MLA-010. Section 17.0 Quantitative Determination Modification: Cone,-the concentrations of target analytes, and the labeled compound concentrations and recoveries, are calculated using the equations below. These procedures are equivalent to those described in the method but are more direct. 72 ------- A,.

These checks will confirm that the above-listed modifications will not negatively affect the accuracy or precision of the reference laboratory results. 7.3.3 Options for High-Level Samples For extremely high level samples (> 1,000,000 pg/g), AXYS may dilute with solvent to the limit for reliable isotope dilution quantification (labeled response > low calibration native response and S:N > 10:1 for both ions). For those samples that do not meet this criterion, a diluted portion of the extract will be respiked with an additional aliquot of surrogate standard, reinjected, and final concentrations for dilution/respike factors and surrogate recoveries using the mean surrogate recovery (excluding any surrogate responses compromised by high-level native presence) will be quantified. 74 ------- Chapter 8 Data Management To ensure that the demonstration data are scientifically valid, defensible, and comparable, appropriate procedures will be used to perform data management. This chapter describes (1) data reduction, (2) data review, (3) data reporting, and (4) data storage procedures for the demonstration. 8.1 Data Reduction Each analytical method selected for the demonstration and each developer technology's instruction manual contain detailed instructions and equations for generation of results. Each developer will be responsible for reducing their own data and providing final results to Battelle in the form described in Table 6-7. The reference laboratory will generate concentration data for the dioxin/furan congeners using EPA Method 1613B and for the WHO PCBs using modified Method 1668A. The reference laboratory concentration data will be converted to TEQ using the WHO 1998 guidance as described in Chapters 1 and 6. The reference laboratory will generate final concentration and TEQ data, and Battelle will review those results through data validation (see Section 8.2.3). Comparisons between the developer and reference laboratory data will be dependent on how the developer is reporting their data (see Sections 1.3 and 6.6.3 for further discussion on this topic). 8.2 Data Review A review of technology and laboratory analytical data will be conducted by each developer and the reference laboratory, respectively. Battelle will also conduct a review of all field and laboratory data. The review processes that will be used for developer and laboratory analytical data are described below. 8.2.1 Data Review by Developers Each developer will review all results generated by its measurement technology. The developer will review all demonstration sample data as well as QC results (such as positive controls/spikes and method blanks) for their technology. The developer will report results to Battelle on the COC/results form (Appendix D) and in the units described in Table 6-7. Battelle will generate a Microsoft™ Excel spreadsheet of each developer's results, including only sample number and developer result, and send the spreadsheet to each developer for review. This will allow the developer to review the results that have been entered by Battelle in electronic form to minimize transcription or interpretation errors. Battelle will not perform any data analysis with the developer data until the spreadsheet has been reviewed by the developer. 75 ------- 8.2.2 Data Review by Reference Laboratory The procedures for data review by the reference laboratory are provided in Appendix I. 8.2.3 Data Review by Battelle In addition to the review process that will be used by the reference laboratory, the Battelle project manager or designee (e.g., such as a Battelle dioxin expert) will review all laboratory and developer results, based on demonstration objectives. The Battelle project manager or designee (such as the QA manager) will also conduct a complete data validation for 100 percent of the data as an independent check of the reference laboratory results. If this validation reveals no oversights or problems, Battelle will consider all data to be acceptable. If oversights or problems are identified, the reference laboratory project manager will be consulted. The reference laboratory data will be compared to the data generated by Battelle during the characterization analyses (see Section 4.3). This will be a key comparison which will confirm the overall quality of the data set. Battelle's assessment of the data and QC results will be summarized for discussion with the EPA program manager and incorporated into the DER. The checklists for performing the data validations are presented in Appendix J. During its data review, Battelle will identify project outlier data using statistical testing and will report these data to the EPA program manager. Project outlier data are defined as sample data outside specified acceptance limits established about the central tendency estimator (the arithmetic mean) of the data set for a given area or for all areas taken together. For data known or assumed to be normally distributed, the specified acceptance limits will be the 95 percent confidence limits defined by the Student's two-tailed t-test. Consistent procedures will be used to identify outliers for both reference laboratory and developer data. No data will be rejected simply because they are statistical outliers, but data may be reported with and without the statistical outliers as appropriate. Battelle will conduct a thorough check to identify the reasons for the outliers and will provide the EPA program manager with an explanation of why some data appear to be outliers. 8.3 Data Reporting Each developer and the reference laboratory will prepare and submit data packages reporting the results of developer and laboratory results, respectively. The reference laboratory will also prepare and submit electronic data deliverables (EDD). Battelle will use these data to prepare the ITVR for each developer technology and the DER for the entire demonstration. Described below are the data reporting require- ments for (1) developer data packages, (2) reference laboratory data packages, (3) ITVRs, and (4) the DER. 8.3.1 Developer Data Packages The developers will compile their results on standard forms provided by Battelle (see Appendix D). The forms will contain sample identification numbers and spaces for a developer to enter their results as appropriate (i.e., each form will be unique to each developer). Electronic reporting of results will not be required. The developers will only be required to report their sample results. Developer-supplied QC sample results will be requested for the DER. Raw data, copies of logbook pages, standards preparation logs, etc. that are included in a typical laboratory data package will not be required from the developers. 76 ------- 8.3.2 Reference Laboratory Data Packages The procedure for data package preparation for the reference laboratory is presented in Appendix K. 8.3.3 Innovative Technology Verification Reports In accordance with the demonstration plan, Battelle will evaluate the performance and cost data collected for each dioxin measurement technology demonstrated and will prepare an ITVR for the technology. Each ITVR will be a focused report of about 100 pages and will include the following: • An introduction • A description of the measurement technology • Site descriptions and the demonstration design • Deviations from the demonstration plan • A description of the reference method and its performance • A description of the technology's performance • An economic analysis • A summary of demonstration results • A verification statement. Battelle will prepare individual ITVRs in accordance with the format specified in the "Handbook for Preparing Office of Research and Development Reports"00' and project-specific guidance from the EPA program manager. The reports will be written in such a way that a reader with a basic science background can understand their contents and make an informed decision regarding the performance of the technologies. The ITVRs will undergo a rigorous review process that will include reviews by the EPA program manager, the developers, and external peer reviewers provided in accordance with the detail and content of previous reports. 8.4 Data Evaluation Report Battelle will prepare a DER containing tabular summaries of investigative and QA/QC data from the demonstration as well as results of technical system and performance audits. The DER will primarily discuss the following: Pre-demonstration activities • Demonstration activities Post-demonstration activities • All developer and reference laboratory demonstration sample data • QA/QC data, including completed audit, observer, and data validation checklists Audit reports. 8.5 Data Storage The reference laboratory analysts responsible for performing measurements will enter raw data into logbooks or on datasheets. In accordance with standard document control procedures, the laboratory will maintain on file the original logbooks or data sheets, which will be signed and dated by the laboratory analysts responsible for them. Similar procedures will be used for all data entered directly into the laboratory information management system. Separate instrument logs will also be maintained by the laboratory to allow reconstruction of the run sequences for individual instruments. The reference laboratory will maintain all raw data, including raw instrument output on tape or diskette, on file for 5 years after the submission of the data packages to Battelle. Data documents will be kept in secure 77 ------- archive file cabinets accessible only to designated laboratory personnel. The data will be disposed of upon receipt of EPA instructions to do so or after 5 years, whichever is sooner. A central project file for the demonstration will be established in the Records Management Office at Battelle's Columbus head- quarters. This file will be a repository for all relevant field and laboratory project documentation. Battelle will offer the central file to the EPA at the end of the demonstration project but will maintain in the central file until the end of the SITE contract if requested to do so. 78 ------- Chapter 9 QA/QC Procedures This chapter describes the QA/QC procedures that will be implemented in this demonstration to ensure that the data generated are of high quality. 9.1 QA/QC Objectives The overall QA objective for the demonstration is to produce well-documented data of known quality. Data quality will be measured in terms of the data's precision, accuracy, representativeness, complete- ness, and comparability. Table 9-1 contains the objectives for the data quality indicators which applies to both the developer and reference laboratory data. If analytical data from the reference laboratory fail to meet the QA objectives described in this section (except for comparability, which does not apply), the source of the errors will be investigated and corrective actions will be taken if necessary and possible. (Corrective actions associated with the reference method are discussed in detail in Section 9.2.)

Developer QC data will be reported to Battelle for inclusion in the DER. The developers process for QC sample analysis will be evaluated and recorded by the Battelle observers. 9.3 Audits, Corrective Actions, and QA Reports The assessment stage involves procedures to verify that project efforts are in compliance with the quality system as the project is being implemented, and that upon conclusion of the data gathering stage of the project, the collected data meet the performance and acceptance criteria (e.g., data quality objectives) specified in the planning stage of the project. The QA manager or designee conducts audits at planned, scheduled intervals; implements provisions for timely responses and implementation of corrective actions if needed; and completes the evaluation process with written reports to technical and management staff. The Battelle project manager will ensure that this individual has sufficient authority, access to project staff, access to documents and records, and organizational freedom to conduct the assessment. 9.3.1 Technical Systems Audits Battelle will conduct a TSA during the time when the reference laboratory is analyzing the demonstration samples. This in-process audit will include a technical systems audit and a quality systems audit and will last one full-day. The work plan for this audit is included in Appendix L. This audit is very similar in focus and scope as the audit that was performed to select AXYS as the reference laboratory. The audit will consist of a short opening conference, a full day of observation of laboratory procedures, records, and interviews with laboratory staff, and a brief closing meeting. Auditors will inspect whether the observations/questions/issues 83 ------- identified during the first TSA (conducted prior to selection of the reference laboratory) are adequately addressed/implemented by the reference laboratory. The TSA will focus on topics specifically related to this project such as: sample and standards tracking, sample and standard preparation, instrument calibration, sample analysis, sample integration and data reduction, and acceptability of quality control data. Records to be reviewed are: Sample receipt records and holding location/conditions Standard (spiking and calibration solution) receipt records and certificates of analysis Standard preparation records • Support equipment records (balances, thermometers) Sample preparation and spiking records Preparation of instrument standards • Preparation of spiking solutions Instrument calibration and maintenance records • Instrument sample run logs • Instrument set-up conditions, temperature programs, calibration and acquisition methods Sample chromatograms • Instrument reports • Quantification techniques • QC sample results • Pre-demonstration sample results Data management procedures • Quality assurance procedures • Data validation and verification procedures Auditors will also review corrective actions from the pre-selection audit. Auditors may submit follow-up questions to the reference laboratory after the audit to address gaps in the observations. A separate TSA will be performed by Battelle at the demonstration site to ensure that the demonstration plan is being implemented properly by Battelle. This will be a self evaluation. The Battelle QA manager will review notebooks, logsheets, chain-of-custody documentation, and observer checklists. The Battelle project manager will be debriefed by the Battelle QA manager at the conclusion of the on-site TSA. The EPA Quality Manager has the authority to conduct an independent technical systems audit at any time during this demonstration. 9.3.2 Corrective Action Procedures Corrective action procedures from TSA findings for the in-process reference laboratory audit or the field demonstration TSA will be documented by the responder and approved by the auditor. Acknowledgment of the response will be provided by the Battelle project manager. The Battelle auditor will then establish a time line for monitoring that the required parties will properly act upon the corrective action(s) within the required time frame. With the Battelle project manager, the Battelle auditor will set measurable milestones for determining that progress is being made on the corrective action and that the corrective action is effective. 9.3.3 QA Reports The outcome of each assessment will be fully documented. The Battelle project manager will archive all audit documentation collected during the project and include it in the DER. The Battelle QA manager or his designee will report the findings of each audit to the Battelle or AXYS Project Manager, as appropriate, who will then address the audit findings and provide an appropriate response. QA 84 ------- reports require a written response by the person performing the inspected activity, and acknowledgment of the audit by the Battelle project manager. Authority to report all TSA results is designated to the Battelle QA manager or his designee. These reports should • Identify and document problems that affect quality and the achievement of objectives required by the demonstration and quality assurance project plan and any associated SOPs, • Identify and cite noteworthy practices that may be shared with others to improve the quality of their operations and products, • Propose recommendations (if requested) for resolving problems that affect quality, • Independently confirm implementation and effectiveness of solutions, and • Provide documented assurance (if requested) to line management that, when problems are identified, further work performed is monitored carefully until the problems are suitably resolved. Responses to adverse findings are addressed immediately during a debriefing after the assessment is completed, and preferably at the site of the assessment. Responses to each adverse finding will be documented in a letter or memo to the Battelle project manager. The letter or memo will indicate for each adverse finding the corrective action(s) taken or planned. The letter or memo will be signed by the appropriate developer or reference laboratory representative. The Battelle QA manager or his designee will review the responses to each adverse finding and will follow up with the Battelle, developer, or reference laboratory representative on any findings that were not adequately addressed. Once all corrective actions associated with the QA report have been verified, the Battelle QA manager or designee will approve the QA report. The QA report and responses to adverse findings will be sent to the Battelle project manager for review and approval. The QA report and responses will be maintained in the QA project files and will be included in the DER 85 ------- Chapter 10 Health and Safety Plan This chapter contains the site health and safety plan for field activities for the dioxin monitoring and measurement demonstration. This plan will be reviewed and signed by all demonstration participants before work begins at the site. The Battelle Project Manager will conduct daily safety briefings before the start of analysis each day to advise and remind the developers of health and safety issues. 86 ------- SECTION 1: GENERAL INFORMATION AND DISCLAIMER CLIENT NAME: PROJECT NAME: SITE DEMONSTRATION U. S. Environmental Protection Agency OF DIOXIN MONITORING AND Superfund Innovative Technology Evaluation (SITE) Program MEASUREMENT TECHNOLOGIES FOR SOIL AND SEDIMENT EPA PROJECT MANAGER: Steve Billets BATTELLE Project Manager: Amy Dindal BATTELLE Site Safety Officer: Amy Dmdal BATTELLE ES&H Representative: Gary Carlin DATE: April 26, 2004 The purpose of this demonstration is to gather technologies capable of measuring dioxin and dioxin-like compounds in soil and sediment in one field location. The demonstration will be conducted near (but not on) a dioxin- contaminated site. The demonstration site will be in the parking lot of the Green Point Environmental Learning Center in Saginaw, MI. Developers of measurement technologies will operate their own technologies inside a trailer or mobile laboratory designated for their use. Battelle will distribute the samples for analyses and observe the operation of the technologies. Battelle will have its own trailer to support overseeing the demonstration, and it will be known as the Battelle Headquarters. This Site Specific Health and Safely Plan (HASP) has been prepared for use by participants in this SITE MMT Demonstration. The plan is written for the specific LEVEL D site conditions, purposes, tasks, dates and personnel specified. If these conditions change, this plan must be amended and reviewed by those named in Section 18. This HASP satisfies the requirements of 29 Code of Federal Regulations (CFR) 1910. Although it does not specifically apply, all site activities shall be performed in accordance with 1910.120(b)(l)(iv) and (v). Battelle will inform the demonstration participants of the site emergency response procedures and any potential fire, explosion, health, safely or other hazards by making this HASP and site information obtained by others available on-site. All participants are responsible for: (1) attending the health and safely briefing given by the Battelle Site Safely Officer (SSO) covering the requirements of this HASP; (2) providing their own personal protective equipment (PPE); (3) providing documentation that their employees have been health and safely trained in accordance with applicable federal, state and local laws and regulations; (4) providing evidence of medical surveillance and medical approvals for their employees (as applicable); and (5) complying with the direction and guidance provided by the SSO. Prior to any demonstration samples being analyzed on site, a pre-work health and safely briefing shall be conducted by the SSO. This briefing shall discuss the chemical and physical hazards associated with this demonstration. Visitors will be briefed on the site-specific health and safely procedures by the SSO.

The trailers and mobile laboratories will be also be cleaned and then wipe tested at the conclusion of the demonstration. Wipe test results must demonstrate that the total TEQ (dioxin/furan and PCB) are <20 pg TEQ/lOOcm2 (http://www.epa. gov/wtc/wipe_samples/censuspdfs/wipe_benchmarks.htm) before a containment facility can be certified as "clean." Samples will be collected in accordance with EPA Methods 1613B and 1668A respectively. Analyses of these samples will be performed by Battelle. A letter describing the cleaning procedure and the analytical results will be provided to the suppliers of the mobile labs and trailers as soon as results are available. Wipe Clearance Test Sampling Overview Samples taken before analyses being will be taken on the floor near the exterior door. Samples taken after analysis by the developers within each temporary containment facility in the following places: 1 sample-fume hood, 1 sample-floor directly in front of fume hood, 1 sample-door knob, 1 blank. The wipe samples will be analyzed for dioxins/furans and the 12 World Health Organization PCBs using EPA Methods 1613B and Method 1668A, respectively. Sampling Procedure Each wipe test sample will be collected in the following fashion: Step 1: A new pair of disposable nitrile gloves will be used to collect each sample. Step 2: Each sample jar will be labeled with the sample ID. Step 3: The sampling solvent will be poured into the j ar containing the wipe test paper. Step 3: The wipe test paper will be removed from the jar after it has been saturated with the sample solvent. Step 4: The wipe test paper will be used to collect a surface sample (one sample per jar). Step 5: The sample collection area will be set as a 10 cm x 10 cm area. This will determined by using a pre- cut 10 cm x 10 cm square as a reference. If the area is of irregular size or shape, the sample area will be estimated so total surface area on the wipe will equal approximately 100 cm2. Step 6: The wipe will be placed back into its respective jar and the lid snuggly screwed back on. Step 7: The sampling time, sampling date, sampler's initials, location of the wipe sample, location of the wipe sample, trailer/mobile lab the sample was taken from, and any comments will be documented. Step 8: Steps 1-7 will be repeated for all samples.

The Battelle SSO shall be notified of all on-site emergencies and be responsible for ensuring that the procedures are followed. The site SSO has ultimate authority during any emergency until relieved by a ranking responder (i.e., local fire department, police department) or until the emergency is brought under control. Personal Injury in the demonstration Designated Emergency Signal: Verbal communication as needed. test area Upon notification of an injury, the Battelle SSO or alternate should evaluate the nature of the injury, and the affected person should be decontaminated to the extent possible prior to movement off site. The on-site CPR/FA personnel shall initiate the appropriate first aid, and contact should be made for an ambulance (and other emergency services as needed) and with the designated medical facility (if required). Fire/Explosion Muster Designated Emergency Signal: 2 short horn blasts Upon notification of a fire or explosion on site, all site personnel will assemble at the Battelle Headquarters. The fire department shall be alerted and all personnel moved to a safe distance from the involved area. Severe Inclement Weather Designated Emergency Signal: Verbal communication as needed. In severe inclement weather (i.e., thunderstorm, tornado, hail, etc.), participants will discontinue operations and go to the Green Point ELC for shelter. If the severe inclement weather occurs when Green Point ELC is closed, participants will discontinue operations and leave the site. Equipment Failure Designated Emergency Signal: Verbal communication as needed. If any other equipment (i.e., portable fume hood) on-site fails to operate properly, the Battelle SSO shall be notified and then determine the effect of this failure on continuing operations on site. If the failure affects the safely of personnel or prevents completion of the demonstration plan tasks, all personnel shall leave the affected temporary containment facility until the situation is evaluated and appropriate actions taken. In all situations, when an on-site emergency results in evacuation of an area, personnel shall not reenter the area until: • The conditions resulting in the emergency have been corrected. • The hazards have been reassessed by the Battelle SSO. • The Site Safely Plan has been reviewed by the Battelle SSO and the Battelle project manager. SECTION 13: SPILL CONTROL PROCEDURES The following procedures will be followed in the event of a spill involving the demonstration samples or the other analytical chemicals brought on site. Spill clean-up materials will be assessed on a case-by-case basis. Spills of Demonstration samples inside of a Temporary Containment Facility Concentrations of contaminants in the test media will be extremely low. Primary concern is migration of trace contaminates. In case of a spill • Barricade the spill area and contact the Battelle SSO. • Don safety glasses and nitrile or latex gloves and obtain a spill cleanup kit from the SSO. • Clean up the spill by first removing any bulk materials using a brush and dust pan or scraper and dust pan (Do not pick up any glass shards by hand). Next, thoroughly wipe down the spill area using a lab towel dampened with acetone. Finally, wash the spill area with a soap and water mixture. • All waste generated from the spill will be placed into a plastic bag (or box if glass is involved) and a yellow waste tag filled out and attached to the bag. The bag will be returned to the Battelle Columbus site for proper disposal. • The Battelle SSO shall determine if wipe test sampling of the area is required. The area should have a piece of plastic taped over it until it is determined if wipe test sampling is required. 95 ------- SECTION 13: SPILL CONTROL PROCEDURES Spills of Demonstration samples on Soil or Parking Lot Concentrations of contaminants in the test media will be extremely low. Primary concern is migration of trace contaminates. In case of a spill • Barricade the spill area and contact the Site Safely Officer. • Don safety glasses and nitrile or latex gloves and obtain a spill cleanup kit. • Clean up the spill by first removing any bulk materials using a brush and dust pan or scraper and dust pan (do not pick up any glass shards by hand). Glass should be placed into a puncture-resistant container. Next, remove any soil or debris that has come into direct contact with the spilled material. • All waste generated from the spill will be placed into a plastic bag and a yellow waste tag filled out and attached to the bag. The bag will be returned to the Battelle Columbus site for proper disposal. • The SSO will determine if wipe test sampling of the area is required. The area should have a piece of plastic taped over it until it is determined if wipe test sampling is required. Spills of Lab chemicals Spills of lab chemicals will be evaluated on a case by case basis. Small spills (involving < 50 ml) of a laboratory chemical in the fume hood can be cleaned up by staff with lab towels. For larger spills, barricade the spill area and contact the SSO. All waste generated from a spill must be segregated and labeled. The SSO will address the disposal of the materials. Spill areas may need to be certified free of dioxin/PCB contamination depending on the type and nature of the spill. The SSO will determine if the certification analysis is necessary. Gas Cylinder leaks In the event of gas leak from any cylinder, the effected trailer will be evacuated until the SSO deemed it safe to reentry. 96 ------- SECTION 14: EMERGENCY INFORMATION (2) LOCAL RESOURCES Ambulance (name): Hospital (name): Police (local or state): Fire (name): On-Site CPR/FA(s): Mobile Medical Response Phone: Covenant Health Care Phone: St Mary's Medical Center Saginaw Police Phone: Saginaw Fire Dept Phone: Mark Misita Phone: 989-758-2900 989-583-2000 989-776-8000 989-759-1288 989-759-1376 614-893-2260 For life-threatening emergencies or emergency trauma care dial 911.

August. 108 ------- ADDENDUM Shortly before making a final commitment to participate in the field demonstration, Paracelsian decided that it did not have the resources to fulfill all of the requirements described in this document. Paracelsian committed to participate in the Visitor's Day activities, but did not plan to analyze any of the samples in the field. Subsequently, Paracelsian determined that it could only commit to analyzing about 25% of the demonstration sample set in their laboratories. It was decided that this was insufficient to draw meaningful conclusions regarding the performance of this technology. As a result, Paracelsian withdrew from further consideration as a full demonstration participant, but agreed to analyze the 15 pre-demonstration samples. The Paracelsian pre-demonstration results will be included in the Data Evaluation Report (DER, see Section 8.4), which may be obtained from the EPA. The DER also will include a limited review of the Paracelsian technology by the Battelle observers during the Visitor's Day. The DER will not be published, and no other published report regarding the performance of the Paracelsian technology will be prepared. ------- APPENDIX A LIST OF DEMONSTRATION PANEL MEMBERS ------- Dioxin SITE Demonstration Panel Participant Fernando Rubio Bob Harrison Randy Allen Noriyoshi Inoue John Gordon, Jeff Sturkey, George Clark Masako Hayakawa/Emmy Leung/ Hiroyuki Hayashi Steve Billets Andy Beliveau Christopher Stitt William Sy Stevie Wilding Nardina Turner Greg Rudloff Allen Debus Barry Evans Craig Smith David Williams Vance Fong Bill Coakley Dwain Winters David E.

Spencer Refuge Manager Shiawassee National Wildlife Refuge 6975 Mower Road Saginaw, Michigan 48601 Dear Mr. Spencer: The purpose of this letter is to request the use of the Green Point Environmental Learning Center ("Green Point") located in the Shiawassee National Wildlife Refuge managed by the U.S. Fish and Wildlife Service to serve as the host site for an upcoming demonstration of dioxin monitoring and measurement technologies. Performance verification of innovative environmental sampling, monitoring, and measurement technologies is an integral part of the regulatory and research mission of the U.S. Environmental Protection Agency (EPA). To address this need, the Superfund Innovative Technology Evaluation (SITE) Program was established by EPA. Additional information regarding the history of this program may be found at our website: http://www.epa.gov/ORD/SITE. One component of SITE is the Monitoring and Measurement Technology (MMT) Program. This Program evaluates the performance of innovative technologies that sample, detect, monitor, or measure hazardous and toxic substances in soil, water, and sediment samples. The SITE MMT Program is currently planning a demonstration of technologies that can be deployed in the field or in a mobile laboratory for the rapid measurement of dioxins in soil and sediment. The EPA has awarded a technical support contract to the Battelle Memorial Institute to assist with this demonstration. We have been working closely with the Michigan Department of Environmental Quality (MDEQ) in planning this demonstration, and dioxin-contaminated samples from the Saginaw area were supplied by MDEQ to be included in this study. As a result of our discussions with the MDEQ and our site selection survey, the EPA requests the use of Green Point Center's parking lot as the demonstration site. We request access for a two-week timeframe, from approximately from April 22, 2004 to May 6, 2004. Use of Green Point's parking lot for this demonstration will entail the following: • Access to site approximately seven trailers in a remote area of the parking lot at Green Point so as not to disturb or impede normal daily activities at Green Point; • Contain all of the analysis to within the trailers; • Conduct a half-day Visitors Day during the demonstration period (approximately April 28), including the use of Green Point's auditorium. For the Visitors Day, the demonstration site would be open to the public so that those interested in using these technologies can learn more about them. • Use of the Green Point building itself would be limited to bathrooms, and possibly phone use should cellular service be an issue. • Not to disturb the grounds or parking area of Green Point in any way. We are committed to leave the area as we found it before conducting the demonstration. ------- This demonstration is fully funded by the SITE Program. Any infrastructure requirements that we have, such as supplying power for the trailers, will be coordinated and paid for through this contract by Battelle. All logistics for this demonstration will be coordinated by Becky Goche. For more information about the dioxin demonstration and this request for use of Green Point's parking lot, please do not hesitate to contact me at 702-798-2232 or by e-mail at billets. stephen@epa.gov. We look forward to working with you and would appreciate your support of this demonstration. Sincerely, Stephen Billets Program Manager U.S. EPA MMT Program cc: G. Rudloff, U.S. EPA, Region 5 A.

Additional Comments: ------- Abraxis Operating Procedure To ensure accurate and reliable results, every effort should be made to perform the coplanar PCB ELISA kit at temperatures between 20°C and 25°C and to allow the reagents to be at the same temperature. The following sample preparation was designed for a quick screen at 625 pg/g. Other sample preparation options are available for lower concentration. 3.4.2.1 Preparation of Sample Extracts From Soil 1. Label soil collection bottles and extract collection vials. 2. Remove the screw cap from the soil collector bottle (containing dispersion device) and collect soil by weight using a digital balance. Place the bottle in an upright position on the balance and tare weight. Weigh 2 ± 0.02 g of soil into the tube. Record the soil weight. 3. Weigh 2 g of soil in a 30-mL high-density polyethylene (HDPE) bottle. 4. Add 6 g of anhydrous sodium sulfate and mix until sample is free flowing. 5. Add 1 steel mixing ball. 6. Add 10 mL of 20% acetone in hexane. Rotate for one hour. 7. Remove the organic extract from the soil particulates by filtration, sedimentation, or centrifugation. 8. Transfer extract to a 40 mL screw cap extraction tube and oxidize using concentrated sulfuric acid (4 mL). Mix by agitation for one minute and allow phases to separate. 9. Remove the organic phase (top layer), transfer to a fresh extraction tube and add 4 mL of concentrated sulfuric acid. Mix by agitation for one minute and allow phases to separate. 10. Repeat step 9 until the acid phase is colorless. 11. Evaporate 1 mL of the organic phase using a nitrogen stream. 12. Redissolve in 0.25 mL of methanol. 13. Add 0.25 mL of water. If cloudy, centrifuge. NOTE: This extraction procedure dilutes the sample by a factor of 2.5. Therefore, assay results need to be multiplied by 2.5 to obtain the final coplanar PCB concentration in the sample. 3.4.2.2 Dilution of Sample Extracts Dilute sample (1:10) by adding 50 jiL of extract to 950 jiL of 50% methanol/water. ------- 3.4.2.3 Assay Procedure 1. Add 50 jiL of anti-coplanar PCB antibody solution successively to each well. 2. Add 50 jiL of the appropriate standard, control, or sample. Using duplicates or triplicates is recommended. Cover the wells with parafilm or tape and mix the contents by moving the strip holder in a circular motion on the benchtop. Be careful not to spill the contents. Incubate at room temperature for 30 minutes. 3. After the incubation, remove the covering and add 50 jil of enzyme conjugate solution to the individual wells. Cover the wells with parafilm or tape and mix the contents by moving the strip holder in a circular motion on the benchtop. Be careful not to spill the contents. Incubate at room temperature for 90 minutes. 4. After the incubation, remove the covering and vigorously shake the contents of the wells into a waste container. Wash the strips 3 times using the IX wash solution with a volume of at least 250 uL per each wash step. Any remaining buffer in the wells should be removed by patting the plate on a dry stack of paper towels. 5. Add 150 uL of color solution successively to each well. Incubate for 20 to 30 minutes. 6. Add 50 uL of stopping solution to each well in the same sequence as for the other reagents. 7. Read absorbance using a microplate reader at 450 nm within 15 minutes after adding the stopping solution. 8. Construct a standard curve by plotting the %B/Bo for each standard on a vertical logit (y axis) versus the corresponding PCB 126 standard concentration on the horizontal logarithmic axis (x) on a graph paper. Alternatively commercial ELISA programs can be used. 9. To obtain the total coplanar PCB TEQ in a sample, multiply sample assay results by the cross-reactivity factor 0.01. ------- Procedural Observations and Questionnaire Of CAPE Technologies Dioxin/Furan Immunoassay Kit Procedure witnessed by: Date witnessed: Time/Date procedure started: Name of Kit Used: Lot Number of Kit: Expiration Date of Kit: Time/Date procedure ended: Individuals Witnessed: Answer the following questions: Question Could this kit be performed in the field without a mobile lab/trailer?

What do you think would be required education/experience for successful operation of this technology? Additional Comments: ------- Cape Technologies Operating Procedure PCDD/Fs are typically extracted with organic solvents that are incompatible with EIA; therefore, a solvent exchange is required. PCDD/Fs have very low volatility and are retained during this solvent exchange in a small volume of a keeper solution (Triton X-100 detergent in TEG) after evaporation of the original solvent. Methanol is added to dilute this solution, and the methanol-TEG-Triton mixture is added directly to the EIA tubes. The solubility of PCDD/Fs in methanol is augmented significantly by adding TEG and Triton X-100. During the first EIA incubation, PCDD/Fs are specifically bound by the anti-dioxin antibodies, which have been immobilized on the EIA tube surface. After washing away the unbound material, the bound PCDD/Fs remain, and a competitor-URP conjugate is added. Bound PCDD/Fs occupy the dioxin binding sites of the antibodies in proportion to the PCDD/F content of the sample and prevent binding of the competitor-URP conjugate. After a short incubation, unbound conjugate is removed, and the test tubes are washed thoroughly. The amount of conjugate bound by the anti-dioxin antibody is inversely related to the amount of PCDD/Fs originally present in the sample. Finally, a solution of chromogenic HRP substrate and hydrogen peroxide is added to the test tubes. Color development is directly proportional to enzyme concentration and inversely related to the PCDD/F concentration in the original sample. The test tubes are analyzed using a tube reader or spectrophotometer to measure the OD. The OD values of unknown samples are compared to the OD values of standards to determine the level of PCDD/Fs in the samples. To ensure accurate and reliable results, every effort should be made to perform the dioxin/furan immunoassay at temperatures between 20* C (68* F) and 25* C (77°F). The following sample preparation procedure was designed for same-day analysis at 500 pg/g, using a one-step cleanup. Other sample preparation options are available for lower concentrations. All sample extraction and extract cleanup components are in a kit form and are disposable. 1. Sodium sulfate is added to a soil sample and mixed. Dimethylformamide (DMF) is added to the soil sample, and the soil is extracted by shaking for two hours. The supernatant DMF extract is removed. DMF extracts are stable for weeks to months at room temperature. 2. Interferences are removed by chemical oxidation. Hexane is added to an aliquot of the DMF extract, then treated with 15% SO3 in concentrated H2SO4 (fuming sulfuric acid). The supernatant hexane is removed and exchanged to a water-miscible organic solvent solution. This hexane-based fuming sulfuric acid cleanup is sufficient for most samples; but, in certain circumstances, an additional cleanup step may be required. This is the case for samples that contain large amounts of non-volatile aliphatic oils. When the DMF extracts of such soils are cleaned using fuming sulfuric acid, the oil is not oxidized; and it remains after evaporation of the hexane, causing a biphasic system when introduced to the EIA first incubation. Such EIA samples appear opalescent or milky, and their results will be invalid because the biphasic system prevents capture of analyte by the antibody. For these samples, a new aliquot of DMF extract is cleaned by carbon adsorption. In this case, the final solvent in the cleanup procedure is toluene rather than hexane. 3. The cleaned sample in hexane or toluene is exchanged to a water-miscible organic solvent solution for EIA analysis. PCDD/Fs have very low volatility and are retained during this solvent exchange in Triton X-100 detergent in TEG after evaporation of the original solvent. Methanol is added to dilute this solution, and the methanol-TEG-Triton mixture is added directly to the EIA tubes. ------- 4. An accurately measured volume of negative control, standard, or prepared sample is mixed with an aqueous sample diluent in test tubes with anti-dioxin antibody immobilized on the surface, and the mixture is incubated. 5. After incubation, antibody tubes are washed, and 0.5 mL of HRP competitor conjugate is added to each tube using a repeater pipettor. Bound PCDD/Fs occupy the dioxin binding sites of the antibodies in proportion to the PCDD/F content of the sample and prevent binding of the competitor-HRP conjugate. After a short incubation, unbound conjugate is removed, and the test tubes are washed thoroughly. 6. A solution of chromogenic HRP substrate and hydrogen peroxide is added to the test tubes. Color development is directly proportional to enzyme concentration and inversely related to the PCDD/F concentration in the original sample. Stop solution is added to each tube using a repeater pipettor to fix the amount of color development. 7. The test tubes are analyzed using a tube reader or spectrophotometer to measure the OD at 450 nanometers. The test is interpreted by measuring the signal produced by a sample and determining the concentration from a dose-response curve constructed from standards tested at the same time. ------- Procedural Observations and Questionnaire Of Hybrizyme Corporation AhRC PCR™ Kit Procedure witnessed by: Date witnessed: Time/Date procedure started: Name of Kit Used: Lot Number of Kit: Expiration Date of Kit: Time/Date procedure ended: Individuals Witnessed: Answer the following questions: Question Could this kit be performed in the field without a mobile lab/trailer?

Add 5 jiL of sample extract in methanol to the activation solution, mix, and shake for 1 hour at room temperature. 2. Transfer to a capture strip Amicrowell@ and shake for 30 minutes at room temperature. 3. Wash the capture strip. 4. Add PCR mix. 5. PCR amplify. Real-time PCR is analyzed by examining "primary growth curves" generated by fluorescent probes within newly synthesized DNA. For quantitative and comparative purposes, a threshold cycle (Ct) is defined for each sample. The threshold may be an arbitrary signal above background, or a certain number of standard deviations above background. The approximate detection limit of the AhRC is less than 0.2 pg TCDD in the assay, according to Hybrizyme. The AhRC PCR™ Kit includes Activation solution (12 vials, 0.5 mL each): Source of Ah receptor and DNA probe (store at -80oC). • Capture strips (1 plate, 8x12 wells): Keep unused strips sealed and in the pouch (store at room temperature). Strip rack included. • Assay buffer (1 bottle, 20 mL): Ready to use (store at room temperature for up to 2 weeks or at 4oC for extended periods of time). Capture reagent (red cap) (1 vial, 0.60 mL): A 16-fold concentrated solution (store at 4oC). Prepare for use by adding 40 L to 600 L of assay buffer. • Primer/probe (white cap) (1 vial, 600 jiL): Forward and reverse primers containing Taqman MGB FAM probe (aliquot, store at 20oC when not in use). • PCR wash concentrate (25X) (2 bottles, 40 mL each): A 25-fold concentrated solution (store at 4oC). Prepare for use by mixing entire contents of one bottle with 960 milliliter (mL) of deionized water. • Glass vials: Rack with 96 vials (flat-bottomed 0.5-mL glass vials with plate). 3.2.2 Operating Procedure 12. Reconstitute PCR wash solution to 1 X with distilled or deionized water for use with an automated plate washer. Prime the plate washer with PCR wash solution. ------- 13. Prepare standards and unknowns in methanol. 14. Prepare the 1 X capture reagent by diluting 40 jiL of stock reagent into 600 jiL of assay buffer for each strip used. Place desired number of strips in the strip frame and re-seal the remainder in the foil pouch. Wash the strips using the "3XWASH" program of the plate washer. Using the multichannel pipetter, dispense 50 jiL to each well in the strip. Shake 60 to 90 minutes. 15. Thaw the activation solution, mixing gently during the process. Do not allow the activation solution to remain at room temperature for more than 20 minutes prior to use. For best results, mix the activation solution vials together prior to dispensing when performing multiple strips. 16. Dispense 50 jiL of the assay buffer into each glass vial using a multichannel pipette. Assay buffer should be at room temperature prior to use. Add 5 jiL of standard or sample. The use of a pipetter (i.e., P-10 Pipetman) with a filter tip is preferred. After adding sample to the entire row, tap gently to mix. Repeat the process for each row of glass vials. 17. Add 50 jiL of activation solution to each glass vial using a multichannel pipette. Shake for 1 hour at room temperature. 18. Wash the strips using the "3XWASH" program of the plate washer. Using a multichannel pipetter, transfer 30 jiL of each reaction to each well. Shake 30 minutes. 19. 8. Wash the strips using the "PCRWash" program of the plate washer. This series of soaks and washes takes about 15 minutes. Thaw the primer/probe solution at this time. 20. Add 100 jiL of primer/probe solution, 400 jiL of water, and 500 jiL of 2 X Universal Master Mix to make each 1,000 jiL of 1 X Master Mix. Dispense 40 jiL into each well. 21. Seal the wells with adhesive tape and cover with two compression pads. Insert the strips into thermocycler and run the "PCR" template. 22. Analyze the data. ------- Procedural Observations and Questionnaire Of Paracelsian, Inc., Ah-IMMUNOASSAY® Procedure witnessed by: Date witnessed: Time/Date procedure started: Name of Kit Used: Lot Number of Kit: Expiration Date of Kit: Time/Date procedure ended: Individuals Witnessed: Answer the following questions: Question Could this kit be performed in the field without a mobile lab/trailer?

Additional Comments: Y N NA Comments ------- Paracelsian Operating Procedure 3.3.2 Operating Procedure The following protocol is for an assay that uses all 96 wells in the 96-well version of the kit. Steps 18 through 21, describing the procedure for the three replicate washes following each incubation, can be automated by a commercial plate washer. Likewise, any residual fluid remaining in the plate wells can be completely removed by a properly adjusted plate washer, thereby eliminating the need for the manual blotting in step 31. 1. Remove the refrigerated components of the kit from cold storage and warm to room temperature. 2. Remove the cytosol components (cytosol, DRE Oligo, ARNT extract, activator) from frozen storage. Thaw up to four 7.5-mL vials of cytosol in a beaker of tepid water. Steps 3 through 9 will generate the activated cytosol. Keep all intermediate mixtures in an ice bath as much as possible. 3. Pool the thawed tubes of cytosol into the 50-mL mixing tube. 4. Add the required volume of DRE Oligo to the pooled cytosol. Return unused DRE Oligo to the freezer. 5. Mix by rocking the tube gently. 6. Add the required volume of ARNT to the cytosol, DRE Oligo mixture. Return unused ARNT to the freezer. 7. Mix by rocking the tube gently. 8. Add the required volume of activator to the cytosol, DRE Oligo, ARNT mixture. Return unused activator to the freezer. 9. Mix immediately (to avoid high local concentrations of salt) by rocking the tube gently. This mixture is the activated cytosol and must be kept on ice. 10. Add 10 L each of one reference standard, one negative control, and up to 10 samples in DMSO (the negative control) to 1.0-mL aliquots of the activated cytosol and mix gently. Tubes for these preparations are supplied by the user. These mixtures compose the treated stock for each type of determination. 11. The 96-well ELISA plate layout will accommodate one negative control, seven dilutions of the TCDD reference standard (or a single dilution of the NAP Standard), and four dilutions of 10 samples, all in duplicate. If less than 96 wells are used, return the unused ELISA strips to 4 C storage in the foil bag with desiccant. 12. Remove the ELISA plate from the desiccated plastic bag and add 400 L of each treated stock to the top row of the wells to give duplicate runs of each of the 10 samples and the single reference standard. 13. With a multichannel pipettor, add 200 L of activated cytosol to all the remaining wells. One of the kit reservoirs will facilitate loading the pipettor. ------- 14. Beginning with the first sets of duplicate wells, make serial dilutions (seven dilutions for the TCDD reference or the single dilution of the NAP, four dilutions for each sample) down the respective plate columns. Individual dilutions are mixed by a minimum of six repetitive aspiration and redispensing cycles of the well contents. The residual waste following the final dilution must be collected for proper disposal. 15. Attach the lid to the plate. 16. Incubate the plate for two hours at 30 C. Incubation at room temperature (i.e., 20 C) is satisfactory, but will result in a slightly lower response. Incubation at a higher temperature (i.e., 37 C) will also result in a lower response. 17. Prepare the 1 X wash buffer by diluting the contents of the 20 X wash buffer bottle to 500 mL with reagent-grade water (250 mL for the 48-well kit). Store unused 1 X wash buffer at 4 C. 18. After the two-hour incubation, remove the well contents by aspiration into a waste receptacle for proper disposal. 19. Add 400 L 1 X wash buffer to all wells, loading the multichannel pipette from a kit reservoir. 20. Wait two minutes. Remove the well contents by aspiration into the waste receptacle for proper disposal. 21. Repeat Steps 19 and 20 twice for a total of three separate washes. 22. Prepare the primary antibody stock by aliquoting the required amount of AB 1 into the appropriate volume of AB diluent. Mix gently. Store unused AB 1 and AB diluent at 4 C. 23. Deliver 200 L AB 1 stock to all wells of the plate, loading the multichannel pipette from a kit reservoir. 24. Incubate the plate for one hour at 30 C. 25. After the one hour incubation, repeat steps 18 through 21. 26. Prepare the secondary antibody stock by aliquoting the required amount of AB 2 into the appropriate volume of AB diluent. Mix gently. Store unused AB 2 and AB diluent at 4 C. 27. Deliver 200 L AB 2 stock to all wells of the plate, loading the multichannel pipette from a kit reservoir. 28. Incubate the plate for one hour at 30 C. 29. After the one-hour incubation, repeat Steps 18 through 21. 30. Prepare the detection reagent stock by dissolving the required number of detection tablets in the appropriate volume of detection buffer with gentle mixing while protected from light. Allow a minimum of 15 minutes for the tablets to completely dissolve. Unused detection buffer and tablets are kept at 4 C. ------- 31. Following the incubation of the final wash, strike the inverted plate against paper toweling to remove residual fluid before proceeding to the next step. 32. Deliver 200 L of the detection reagent stock from Step 30 to all wells of the plate, loading the multichannel pipette from a kit reservoir. 33. Incubate the plate at 30 C while protected from light. Residual moisture from condensation and/or from contact with incubator water must be carefully blotted from the plate before reading. The plate is read at 405 nanometers (nm) after 15, 30, 45, and 60 minutes. Variations in incubation temperatures and plate reader characteristics may dictate the best incubation times for individual conditions. A standard curve is used to determine the amount of TCDD equivalents present in a sample. The standard curve is generated by plotting the average absorbance (OD) measured at 405 nm for each of the TCDD reference standards on the vertical (Y) axis versus the corresponding quantity (pg) of TCDD on the horizontal (X) axis. Results are calculated manually using graph paper or a curve-fitting statistical software package. The TCDD equivalents for the samples are determined from the standard curve by interpolating from the absorbance value (Y axis) to the quantity (pg) of TCDD (X axis). The initial TCDD concentration in the sample is found by correcting for the sample dilution. The supplied NAP solution, at 2 L per test well, may optionally be used as a single-point positive control that is equivalent to 32 pg TCDD. ------- Procedural Observations and Questionnaire Of WAKO Dioxin ELISA Kit Procedure witnessed by: Date witnessed: Time/Date procedure started: Name of Kit Used: Lot Number of Kit: Expiration Date of Kit: Time/Date procedure ended: Individuals Witnessed: Answer the following questions: Question Could this kit be performed in the field without a mobile lab/trailer?

Additional Comments: Y N NA Comments ------- WAKODioxin ELISA Kit Operating Procedure The Dioxin ELISA Kit should be used at room temperature (20« «to 25« C) and stored at 2« «to 10« C. 1. To prepare the PC solution (5,000 pg/mL), add 2.0 mL of methanol to the tube containing the PC. Then, gently stir the tube four or five times, and leave it at room temperature for 10 minutes. Gentle stirring is repeated once more before use. Do not vigorously shake or vortex the solution to avoid PC material adhering to the tube wall. The solution can be used within four weeks at 2« «to 10« C after reconstitution. 2. Prepare the dilution solution by dispensing 2 mL of sample solubilizer in a tube and adding 2 mL of methanol. 3. Prepare 1/10-fold diluted PC solution (500 nanograms/mL) by adding 900 uL of dilution solution to a disposable culture tube rinsed with acetone and dried. Then add 100 uL of concentrated PC solution and gently stir the tube two or three times. Leave the tube at room temperature. The solution can be used after pipetting it up and down two or three times. 4. Prepare PC dilution solutions for the standard curve using the 1/10-fold diluted PC solution described above as follows: Tube Number: Concentration Dilution solution Concentrated PC solution 1/1 0-fold diluted PC solution Total volume 1 0 pg/mL 500 uL - 0 uL 500 uL 2 40 pg/mL 460 uL - 40 uL 500 uL 3 100 pg/mL 400 uL - lOOuL 500 uL 4 250 pg/mL 250 uL - 250uL 500 uL 5 500 pg/mL 450 uL 50 uL - 500 uL 6 l,OOOpg/mL 400 uL 100 uL - 500 uL 7 2,500 pg/mL 250 uL 250 uL - 500 uL 5. Dry the contents of each tube. 6. To prepare a dilution series of PC solutions, add 500 \\L of Buffer B to each tube, lightly stir it with a vortex mixer, and centrifuge it at 2,000 revolutions per minute (rpm) at room temperature to collect the solution at the bottom. 7. To prepare the primary antibody stock solution, add 200 uL of purified water to the tube and gently stir it, then leave the tube for 10 minutes at room temperature. The solution can be used within four weeks. 8. Rinse a beaker or a 5- to 10-mL vial with acetone and air dry on clean paper towels. 9. Prepare the primary antibody working solution using a 100-fold dilution of the primary antibody stock solution described above with Buffer A according to assay sample numbers and volumes. Stir the diluted solution gently several times, and leave it at room temperature for 10 minutes. Stir the solution several times just before use. The solution cannot be stored prior to use. 10. Prepare the POD-conjugate solution by adding 4 mL of Buffer A to the tube and gently stir several times. Leave the tube at room temperature for 10 minutes. Gently stir the tube just before use. The solution can be used within two weeks when stored at 2- 4o 10- C. 11. Fix the necessary number of microplate wells (coated with the secondary antibody) to a microplate holder with Scotch tape. Place the holder in a closed box, and store it in a refrigerator for at least 30 minutes before use. 12. Add 100 uL of Buffer B to the tube containing the material obtained by sample pretreatment, and gently stir the solution along the inner surface of the tube several times with vortex mixer. Briefly centrifuge the tube at 2,000 rpm for five minutes to collect the solution at the bottom. 13. Line up the tubes containing the dilution series of PC solutions and the samples resolved in Buffer B in a tube rack. Dispense an equal volume of the primary antibody working solution to each tube. 14. Immediately, agitate the solutions several times, then seal the tubes with Parafilm and leave them at room temperature for 30 minutes. 15. During the incubation, prepare chilled water containing ice in a water bath and sink the tubes under the water in the bath. After the 30 minute-incubation at room temperature, add 250 uL and 50 uL of POD-conjugate solution to the tubes containing the diluted PC solutions and those containing sample material, respectively. 16. Gently agitate the tubes several times, and leave them for 10 minutes. Avoid vigorous shaking with the vortex because dioxins may adsorb to the tube wall. ------- 17. Take the microplate holder from the box stored in a refrigerator. Dispense 100 uL of the reaction mixture to the wells. Briefly agitate the solutions in the wells. Seal the wells with Parafilm, return the holder to the box, and store the box in a refrigerator at 2- -to 10- C for 18 to 20 hours. 18. On the second day, prepare the wash solution by diluting the wash solution concentrate (x 6) with five volumes of purified water. The solution volume prepared can be adjusted depending upon the number of wells used. Usually, one well needs 1.2 mL of the wash solution. The solution can be used within two weeks after dilution when stored at 2' -to 10' C. 19. Prepare the necessary volume of color-developing solution by mixing the substrate and the citrate buffer in a ratio of 1:50 just before use. (The tube used in this preparation should be cleaned with purified water.) Add the citrate buffer to the tube, then the substrate. Avoid vigorous agitation of the mixed solution because it may cause crystalization. 20. Take the well holder from the box stored in a refrigerator, and remove the seal from the wells. Remove the reaction mixture from the wells, being careful not to spread the solution to the holder. Lightly tap the holder upside down on sheets of paper to remove the residual mixture in the wells. Dispense approximately 0.35 mL of wash solution to each well, and then drain the solution, being careful not to spread the solution to the holder. Remove the solution from the well walls by tapping the holder upside down on the papers. Repeat washing twice. At the last washing, remove the solution by tapping as much as possible. 21. For the enzyme reaction, dispense 100 uL of the color-developing solution to all the wells. Seal with Parafilm, cover the holder with aluminum foil to interrupt light, and leave the holder at room temperature for 30 minutes. Stop the reaction by adding 100 uL of stop solution in the same order as the color-developing solution was added. Tap the side of the holder to mix the solution. Read the signal with a microplate reader at 450 nm or at 450/650 nm within 15 minutes after stopping the reaction. Construct the standard curve obtained with the diluted PC solutions and estimate the dioxin concentrations of samples as 3,7,8-TCCD. The primary antibody used in this kit reacts with 2,3,7,8-TCCD and 3,7,8-TCCD with equal intensity. 22. In estimating the dioxin concentration, it is useful to plot the obtained values with a regression of polynomial quadratic equation or four-parameter logic after log-logit conversion. ------- Procedural Observations and Questionnaire Of Xenobiotics Detection Systems, Inc.

CALVX ® Operating Procedure 3.6.2 Operating Procedure Xenobiotic Detection Systems, Inc. has a patented genetically engineered cell line (mouse hepatoma H1L1) that contains the gene for firefly luciferase under transactivational control of the AhR. This cell line can be used for the detection and relative quantification of a sample's total dioxin I-TEQ. Using a patent pending sample processing procedure, it is also possible to use the CALUX® by Xenobiotic Detection Systems assay to estimate the I-TEQ contributions of PCDDs/Fs or the I-TEQ contributions of the coplanar PCBs. The assay that uses this cell line is called the Chemical-Activated Luciferase Expression or CALUX® by Xenobiotic Detection Systems assay. The samples are extracted using a modification of the EPA 8290 extraction method. Briefly, the dried samples are ground and 1-g aliquots are placed in solvent-cleaned glass vials with polytetrafluoroethylene-lined caps. The sample is extracted with a 20% solution of methanol in toluene then twice with toluene. During each extraction step, the samples are incubated in an ultrasonic water bath. The three extracts from each sample are filtered, pooled, and concentrated by vacuum centrifugation. The sample extract is suspended in hexane and prepared for the bioassay by a proprietary cleanup method. The eluate from the cleanup method is concentrated under vacuum into DMSO. The DMSO solution is used to dose the genetically engineered cells in the CALUX® by Xenobiotic Detection Systems assay. Prior to dosing the cells, the sample extracts in DMSO are suspended in cell culture medium. This medium is then used to expose monolayers of the H1L1 cell line grown in 96-well culture plates. In addition to the samples, a standard curve of 2,3,7,8-TCDD is assayed (161, 80.5, 40.2, 20.1, 10.1, 5.0, 2.5, 1.2, and 0.6 ppt TCDD). The plates are incubated for a time to produce optimal expression of the luciferase activity in a humidified CO2 incubator. Following incubation, the medium is removed and the cells are examined microscopically for viability. The induction of luciferase activity is quantified using the luciferase assay kit from Promega. ------- APPENDIX F AXYS ANALYTICAL SERVICES STATEMENT OF WORK ------- Statement of Work AXYS Analytical Services Ltd. SITE Demonstration for Dioxin Monitoring and Measurement Technologies AXYS Project Manager: Georgina Brooks Battelle Project Manager: Amy Dindal Phone: 250-655-5800 Phone: 561-422-0113 Email: gbrooks@axys.com Email: dindala@battelle.org Battelle Memorial Institute is conducting a field demonstration of dioxin monitoring and measurement technologies under the U.S. Environmental Protection Agency's (EPA) Superfund Innovative Technology Evaluation (SITE) Program. In April 2004, developers of innovative dioxin measurement technologies will gather at a field demonstration site in Saginaw, MI to analyze dioxin-contaminated soil, sediment, and extract samples. A reference laboratory will be concurrently analyzing replicate splits of the samples by high resolution mass spectrometry (HRMS). The reference laboratory, AXYS Analytical Services, Ltd. (Sidney, British Columbia, Canada), will analyze samples for 17 dioxin/furans and the 12 World Health Organization dioxin-like poly chlorinated biphenyl (WHO PCB) congeners in 13 soil/sediment samples and 2 extracts for the pre- demonstration phase of the project and 186 soil/sediment samples and 23 extracts in the demonstration phase of the project. AXYS will also be responsible for the preparation of the extract samples. The purpose of this statement of work is to describe in detail the analytical services to be procured from AXYS for this project. AXYS will provide reference analytical measurements for dioxin/furans (D/F) using EPA Method 1613B and for the 12 WHO PCBs using EPA Method 1668A. The congeners to be reported and their associated toxic equivalency factors (TEFs) are provided in Table 1. The following is a list of the major tasks that will be completed by AXYS. Task 1: D/F and PCB Analysis. Approximately 200 soil/sediment samples will be provided by Battelle to AXYS for analysis by both 1613B and 1668A. AXYS will receive -13 samples as soon as this purchase order is in place (pre-demonstration phase), and the remaining 186 samples in mid-April (demonstration phase). AXYS will also generate and analyze 25 extracts in Tasks 2 and 3 below for 1613B and 1668A analysis. Two extracts will be prepared and analyzed immediately after this purchase order is in place (pre-demonstration phase). Twenty-three extracts will be prepared and analyzed in late April (demonstration phase). Task 2: Soil Extract Preparation. Battelle will provide AXYS with approximately ninelOO g soil samples. AXYS will extract each 100 g sample according to Dean Stark extraction procedure for 1613B, with the exception of surrogate spiking which will be spiked (after aliquot splitting step) into the AXYS aliquot only. AXYS will split the extract into 11 equal aliquots. Each aliquot will be concentrated to 10 mL and put in a heat-sealed ampoule. Each ampoule will be labeled per Battelle's instructions. Six of the 11 ampoules will be shipped by Federal Express according to Battelle's directions. One ------- Table 1.

AXYS will provide written text describing the extraction, clean-up, analysis, quality control checks, data reporting, data review, and data packaging procedures for the project demonstration plan. AXYS will also participate in project conference calls as requested. AXYS will also host an on-site audit while the demonstration samples are being analyzed. Battelle anticipates that this audit will occur in mid-May, around the time when the first batch of data are being finalized and reported. Project Requirements The following are technical requirements for this project that AXYS is expected to follow. Any deviation from these requirements should be discussed in advance with Battelle's project manager. • AXYS's standard electronic data deliverable (EDD) will be delivered to Battelle's project manager by email, at no additional charge, by the due date committed by AXYS in Table 3. A complete, auditable data package is also required for each sample. The paginated data package will be delivered to the Battelle project manager by hard copy and CD within 5 days of the EDD being delivered. The narrative for the data package will include the sample extraction weight for each sample. ------- • Final reporting deliverable turn around time for the pre-demonstration samples will be 21 days. Data packages for the demonstration samples will be delivered to Battelle according to the schedule in Table 3 (at 1-week intervals starting with Week 4 of the project). Final reporting deliverable turn around time for the demonstration samples will be no more than 90 days from receipt of samples. Table 3.

Regular soxhlet extraction will be used for the PCB analysis. • Percent moisture measurements do not need to be performed. • A six-point initial calibration, including a low level calibration point (at 0.2 ng/mL), will be performed for 1613B. The standard five-point calibration will be performed for 1668A. • All sample processing, clean-up, analysis, and reporting will follow EPA Method 1613B and 1668 A except for the method modifications defined in the AXYS's standard operating procedures (SOPs). • The data will be reported as both concentration (for each target analyte), total concentration, TEQ (for each target analyte), and total TEQ. TEQ will be calculated and reported two ways: using both the WHO TEFs (listed in Table 1) and using both a value of zero and l/2 the detection limit when the analyte is not detected. The extract samples are to be reported in pg/mL TEQ. • The static mass resolution check will be demonstrated every 12 hours. ------- The following will be standard with each analytical batch. Results for quality control (QC) samples must meet method/SOP requirements. o No more than 20 samples will be included in each batch. o One procedural blank will be included in each batch. o One demonstration sample, of AXYS's choosing, will be analyzed in duplicate with each batch. o Surrogates will be spiked in each sample, except for the soil and spiked extracts that are prepared for the participants. o A spiked matrix (OPR or SRM) will be analyzed and reported with each batch. o Daily calibration check will occur every 12 hours. o A column carryover solvent blank will be run after each calibration standard to demonstrate instrumental carry over rate. Sample responses will be evaluated using the demonstrated instrumental carryover information to ensure that results are not significantly affected by carryover from a previously injected sample of higher concentration. Where the data indicates this may have occurred the sample in question will be re-injected. The pre-demonstration samples will be analyzed completely blind by AXYS. For the demonstration samples, Battelle will identify which sites the samples are from, and AXYS can refer to the pre-demonstration results so that congener patterns and approximate dilutions can be estimated. Battelle will also identify which samples are anticipated to contain high levels (> 10,000 pg/g) so that AXYS can take pre-cautionary measures to deal with these samples. AXYS will report sample specific detection limits, as specified in their response to the SITE demonstration questionnaire. AXYS will flag any low level detections that are lower than the lowest calibration standard. A carbon column cleanup step to isolate toxic PCBs will be performed and the DB-1 column will be used as the primary column. Secondary column confirmation for 2,3,7,8-TCDF will be performed for every sample. Analytical data generated by AXYS for this project will be backed-up on a weekly basis. The data shall remain on the instruments (or, at a minimum, readily accessible) until the reports for this project are finalized in December 2004. All project files and supporting data will be archived for a minimum of 5 years. ------- APPENDIX G QUESTIONNAIRE FOR REFERENCE LABORATORY SELECTION ------- Inquiry Regarding Participation in EPA SITE Demonstration Program Statement of Work The purpose of this inquiry is to identify laboratories that are interested in providing dioxin analyses in support of the US Environmental Protection Agency (EPA) Superfund Innovative Technology Evaluation (SITE) Program. In April 2004, developers of innovative dioxin monitoring and measurement technologies will gather at a field demonstration site in Saginaw, MI to analyze approximately 200 dioxin-contaminated soil and sediment samples. A reference laboratory will be concurrently analyzing a replicate split of the samples by Method 1613B for the 17 dioxin/furan congeners and by EPA Method 1668A for the 12 World Health Organization PCBs, with concentrations ranging from < 1 pg/g to > 10,000 pg/g. The data generated during the field demonstration will be used to prepare Innovative Technology Evaluation Reports for each of the participating technologies. Each report will be a comprehensive evaluation of the technology's ability to measure dioxin in contaminated soil and sediment, including a comparison to the HRMS method results, so the selection of a laboratory to perform these analyses is a critical step in the process. If you are interested in being considered for selection, please answer the following questions and provide your answers to Battelle Memorial Institute, who is the contractor that is conducting the demonstration for EPA. Responses are to be submitted by email or fax no later than Tuesday, December 23, 2003 to Amy Dindal, dindala@battelle.org, phone: 561-422-0113, fax: 561-258-0777. 1) List all dioxin and PCB methods that you routinely perform. State whether you are running modifications of methods and note what the modifications are. List any certifications that you hold for performing each analysis, as applicable. List the approximate number of analyses your lab performed by each method in 2003. Also provide a quote on a per sample basis if you were to receive 15 soil samples in one batch in February 2004 and 200 soil samples in one batch in March 2004 for analysis by those methods. EPA Method Modifications (Y/N - if Y explain on separate sheet) Certifications (Y/N- if Y please attach) Number of analyses in 2003 Quote for 215 sample analyses ------- 2) List the make, model, age, and number of analytical instruments that would be available for use in this study. 3) Describe how many samples will constitute a sample batch and the associated quality control samples that will be analyzed with each batch. 4) Define the congeners and concentrations in the lowest calibration standard typically analyzed in your lab. 5) Describe how you determine the method detection limit with and without background present. Be sure to include the size of sample required and list the detection limits on a congener specific basis. 6) List the most recent EPA contracts you held for the analysis of dioxin in soil or sediment and how many samples were analyzed for each contract. ------- 7) Will you accept high level samples (> 10,000 pg/g D/F; > 100 ppm PCB)? If so, does the quote provided in the table include dilution/re-analysis or re-extraction with smaller amounts to accommodate higher level samples, or will there be an additional fee? 8) Are you willing to have a representative of your laboratory serve on the project's advisory panel? This would include participating in conference calls and reviewing documents (10-20 hours). Would there be an additional charge for this service or would this be included as part of the project participation? 9) Describe your process for data review from the time the data is generated until it is reported to the client (e.g., what percentage is reviewed by the analyst, QA officer, manager, etc.). 10) What would you need/want to know about a sample prior to analysis? 11) What is your current sample load for these methods? Could you complete the 15 samples received in February within 21 days? Could you complete 200 samples received in March within 160 days of receipt? 12) Are you willing to run three PE samples and host an onsite audit of your laboratory in January? Can you provide the results and a data package for these samples within!4 days of receipt? Would you be willing to do these analyses free of charge and, if not, what would be the cost per sample? ------- 13) Would you provide a representative data package for review prior to receiving the PE samples?

No.: Date: Page: SQA-018(QAQC-18) 3 28 May 2002 1 of 5. Purpose This document describes specific protocols for quality review of all PCDD/F results and data packages from application of USEPA Method 1613B to environmental samples. Scope Axys SOP # QAQC-01 describes the general procedures for conducting a final quality review of analytical data and should be consulted along with this document which contains complimentary method specific details for review of USEPA 1613B results. Requirement and Authority This review must be completed for all data reports and data packages prior to release to clients. The review is conducted by designated QA Chemists fully trained in application of Method 1613B who report to the QA Manager. QA Chemists assess the acceptability of results and have the authority to request corrective actions to bring any results not meeting specifications into conformance. The QA Manager, or the designee, has final responsibility for ensuring that data reviews are conducted properly and for final decisions on data acceptability. Definitions of Terms Used Terminology used in this document is consistent with that of Method 1613B. The following additional terms are used: PCDD - Polychlorinated dibenzo-p-dioxins PCDF - Polychlorinated dibenzofurans TCDD -Tetrachlorinated dibenzo-p-dioxin TCDF - Tetrachlorinated dibenzofurans Sample Specific Detection Limit (SDL) - detection limits calculated from an estimation of instrumental noise converted to a final concentration in the same manner that target compound peak responses are converted to final concentrations. Procedures Sample Receipt, Holding Times, Preservation Sample Receipt forms must be completed fully including USEPA Sample Login Sheet DC-1 where required. ------- This document is the property of Axys Analytical Services Ltd and contains proprietary and confidential information.

No.: 3 Date: 28 May 2002 Area: QA/QC Page: 2 of 5. Method 1613B requires that aqueous samples be stored at 0-4 °C and that solids/semi-solids/ oily/mixed phase/tissue samples be stored at <4 °C from time of collection until receipt at the laboratory. Contract specific guidelines may also apply. USEPA contract guidelines require that the client be informed if the shipping cooler temperature exceeds 10 °C upon receipt at laboratory. Method 1613B requires that aqueous samples be stored at 0-4 °C and solids/semi-solids/ oily/mixed phase/tissue samples be stored at <10 °C in the laboratory. There are no demonstrated storage times for PCDD/F and Method 1613B defaults to a one- year holding time. Method 1613B specifies that if the PH of aqueous samples exceeds 9.0 they be adjusted to PH 7-9 with sulphuric acid and that any free chlorine be neutralized with 80 mg/l of sodium thiosulfate. These procedures are to be done at the sampling stage. Some clients may choose to waive this requirement or arrange for it to be done upon receipt at the lab. Note any departures from the 1613B method protocol in the narrative. Method Performance Documentation Inspection - Annual Initial Performance and Recovery study results fall within limits in Method 1613B Table 6. - Annual Method Detection Limit study results fall below one-third the minimum levels in Method 1613BTable2.

No.: Date: Page: QAQC-1 4 01 May 2001 1 of 4 Purpose: To review analytical data prior to release to ensure reported results satisfy all quality and contract specific criteria Scope: Analytical raw data are converted to sample concentrations and final data reports by a team of data interpretation and report preparation specialists in the Data Production Group. In addition to the data quality checks performed during that process, a final data quality review is conducted by the Quality Assurance Group prior to release of results. This SOP describes the general procedures for conducting the final data review. Requirement and Authority All final data reports are subjected to a comprehensive review prior to release and the results of the review are documented. The review is conducted by designated QA Chemists reporting to the QA Manager. QA Chemists judge the acceptability of results and are responsible for ensuring the accuracy and completeness of work. They have the authority to request confirmation or corrective action such as additional documentation, re-injections, or analysis repeats. QA chemists provide the Supervisors, Lab Manager, Chemists, and QA Manager with information and advice regarding work quality, corrective action and special job requirements. Feedback is provided on the quality of work-up, instrumental analysis, interpretation, coding, calculation, reporting, tracking, interlab communication, and documentation. The QA Manager, or the designee, has final responsibility for ensuring that data reviews are conducted properly and for the accuracy of final reports.

Complete the shipping information on the Data Package and Shipment Log (FSA-023). 6. Prior to shipment, the Receptionist verifies the shipping address on the letter with previous shipping information for the client and reports any discrepancies to a Data Packager. If necessary, the Data Packager prepares a new covering letter. The Receptionist places a waybill on the box and checks that the name and address on the waybill are the same as on the letter taped to the box. When the waybill is in place, the letter is removed from the outside of the box. 7. The Receptionist tracks the package with the courier and maintains files of the shipping information. 8. The Receptionist sends original copies of shipping records to the accounting department. 9. File the third copy of the covering letter in the Data Package binder and give the fourth copy to the Accounts Receivable Technician. ------- This document is the property of AXYS Analytical Services Ltd. and contains proprietary and confidential information.

Forms 1A,2 • Extra Work Analysis Data: i.e. dilution, recolumn, reinjection (target reports, surrogate reports). Forms 1A, 2 (organize multiple dilutions by run date) • Client Standards, if applicable. Form 1A • Homologue Totals - if required or not on initial analysis report • TEQ - if required or not on initial analysis report. Form 1A • Aroclors - if required • If there is Lipid weight basis analysis results, organize similarly (do not worry about surrogate pages being with reports)- For a paper data package all wet wt basis data is organized by L number, Samples -1 through -x and all lipid wt data is in a separate section also organized by L number samples -1 through -x. In the paper DP this is separated by a coloured cover page. ON A CD DP, the lipid data comes immediately after the chromatogram for the wet wt data for a given L number. ------- APPENDIX L WORK PLAN FOR REFERENCE LABORATORY IN-PROCESS AUDIT ------- AUDIT PLAN SITE Demonstration of Monitoring and Measurement Technologies for Dioxin and Dioxin-like Compounds in Soil and Sediment Subtask: In-Process Laboratory Audit Client: EPA NERL, SITE Program (FEATS contract) Project Manager: Amy Dindal (Battelle Columbus Laboratories) Assessee Organizations: AXYS Analytical Services, LTD Location: 2045 Mills Rd.
