The Consent Order identified a series o f requirements and tasks to be performed by the parties (WVDEP, WVDHHR-BPH, and DuPont) in order to determine whether there has been an impact on human health and the environment as a result o f releases o f ammonium perfluorooctanoate (C-8), CAS Number 3825-26-1, to the environment from DuPont operations at the Washington Works facility (facility) and the associated landfills (Local, Letart, and Dry Run). The Consent Order established the C-8 Groundwater Investigation Steering Team (GIST) to oversee investigations and activities that will be conducted to assess the presence and extent of C-8 in drinking water, groundwater, and surface-water at and around the facility and the Local, Letart, and Dry Run Landfills. Pursuant to Attachment A of the Consent Order, three primary tasks will be performed by DuPont and evaluated by the GIST. These tasks (Tasks A, B, and C) are described briefly . below: - Task A: Conduct Groundwater Use and Well Survey/Groundwater M onitoring -this task involves evaluating C-8 in groundwater initially within a one-mile radius from the facility and the landfills and public water supplies upstream and 10 miles downstream o f the facility along the Ohio River. Currently, four reports have been issued documenting the surveying activities (DuPont 2002a; 2002b; 2002c; and 2002d). These reports provide the results for one-mile radius surveys around the Washington Works Facility/Local Landfill, Letart T-nndfiH, Dry Run Landfill, and In Washington County, Ohio. In addition, results for the two-mile radius survey around the Washington Works FacSlity/Local Landfill and for public water supplies along the Ohio River are presented. two-mile survey in Washington County Ohio has recently been completed, and a report documenting these activities is in preparation. Quarterly monitoring o f C-8 at three public water supplies (Tuppers Plains, Lubeck, and Little Hocking) is ongoing, Task B: Assessment of Existing Groundwater and Surface W ater Monitoring Data - this task comprises three subtasks: Compile historical C-8 data. * Sample monitoring wells and outfalls at the facility and associated landfills. Develop a Groundwater Monitoring Plan for the facility. The first and third subtasks were completed and submitted to the GIST for review. Subtask 2 is an ongoing task conducted monthly for required surface-water sampling points and quarterly for groundwater and for non-required surface-water sampling points. Sampling results are submitted monthly and/or quarterly t the GIST. rivertesulls.doc Nov. 19,02 Wilmington, DE A SH 019659 E D 630091 DRAFT Ohio RiverWaterSampling Resulte Introduction Task Ci Plum e Identification/Groundwater Assessment - this task includes evaluating the vertical and horizontal extent of C-8 impacted groundwater and specifically includes an assessment o f C-8 impacted groundwater at the Letart Landfill and its impact on the Ohio River and public water supplies along the river. Drilling o f new monitoring wells has been completed at the Washington Works Facility and at die Local, Letart, and Dry Run Landfills. C-8 sampling o f the all monitoring wells was recently completed, and C-8 analysis is underway. In addition to the tasks described above, the GIST also recommended that DuPont conduct a river investigation to assess if -8 impacted groundwater at the facility is impacting the Ohio River. DuPont agreed with this request and the Ohio River Water Sampling Proposal for the Washington Works facility and the Letart Landfill was submitted in February 2002 to th GIST. This proposal was subsequently approved by the GIST. Shortly after approval, the Ohio Environmental Protection Agency (Ohio EPA) reviewed the proposal and recommended slight modifications. DuPont agreed to change the proposal as recommended by Ohio EPA (DuPont letter to Ohio EPA, dated April 1,2002). Sampling activities were conducted in June, July, and October 2002, This report presents the results o f the Ohio River water sampling and is organized in the following manner: - Section 2 provides information on C-8 analyses and analytical reporting. Section 3 presents the Ohio River water C-8 results for locations upstream, adjacent to and downstream o f the Washington Works Facility. Section 4 provides the Ohio River water C-8 results for locations sampled adjacent to Letart Landfill, Section 5 presents the Ohio River parameters. Q Section 6 provides references. riveitesults.cioc Nov. 19,02 Wilmington, DE 2 -, A SH 019660 E ID 630 92 I DRAFT Ohio River Water Sampling Resulte C-8 Analyses and Analytical Reporting I I I I I I I ,1 Ii I I I I I I 2.0 C-8 ANALYSES AND ANALYTICAL REPORTING The Quality Assurance Project Plan (QAPP; DuPont, 20Q2e) discusses the procedures and protocols developed to ensure that project information, data, and decisions derived from or based on data acquired during toe C-8 investigation at Washington Works Facility and associated landfills are technically sound, usable, and properly documented. The QAPP was submitted to the GIST in January 2002. Specifically, Sections 5 ,6, and 10 present sampling protocols, sample and document custody procedures, and internal quality control checks that were followed during the field sampling activities associated with toe groundwater well and water-use survey. The QAPP also presents information on quality assurance, calibration procedures and frequency, analytical procedures, data reduction, verification, and reporting. Information on the analytical method and the precision criteria used for the C-8 reporting are summarized below. in October 2001, Bxygen Research, Inc. (Exygen), located in State College, Pennsylvania, developed and tested a new analytical method that utilizes Liquid ' Chromatography/Tandem Mass Spectrometry (LC/MS/MS). DuPont adopted this method (LC/MS/MS) for analyzing C-8 in water in November 2001, Currently, Exygen performs all C-8 water sample analyses for DuPont. Exygen reports C-8 results for the laboratory replicate o f each field sample. These results are evaluated for precision by comparing the field sample result to the corresponding laboratory replicate result: If both results are less than toe practical quantitation limit (PQL), the replicate sample for that analyte is considered to have passed the precision criteria. If one or both results are between one and five times the PQL, the replicate is considered to have met the precision criteria if the two results differ by less than the PQL. Q I f one result is less than the PQL and toe other is not and if the two results differed by a value less than the PQL, the replicate is said to have met the acceptance criteria. O If both results are at least five times toe PQL, toe replicate is considered to have met toe criteria if toe relative percent difference (RPD) between the two results is less than or equal to 20%. The RPD is the absolute value o f the difference o f two measurements divided by their average. When the precision criteria outlined above are met, Exygen reports the average o f the field sample and the laboratory replicate results reported. I f criteria for precision are exceeded, Exygen reports toe higher o f toe sample and laboratory replicate results* Finally, when one result (from the sample/laboratory replicate pair) is above toe PQL and one below, toe result that is above the PQL is reported. C-8 results are recorded in the Corporate Environmental Database (CED) and are reported as FC-143 for consistency with historical results. fivenesults.doc Nov. 19,02 Wilmington, DE 3 A SH 019661 E ID 630093 DRAFT Ohio River Water Sampling Results C-8 Analyses and Analytical Reporting Ail aliquot o f each field sample is also analyzed as a matrix spike (MS). Results o f the MS analysis are used to assess accuracy. The MS recovery value must fall between 70 to 130%, radess the sample concentration is at least four times the amount spiked. The maximum amount used to spike field samples is 500 ug/L. All data packages generated b y Exygen are reviewed in-house for compliance with the laboratory Standard Operating Procedures (SOP) and data usability, using the checklist provided in the QAPP, Results o f the in-house review indicate that data reported by Exygen have been generated in compliance with the laboratory SOP, with few exceptions as noted in the individual review summaries. All data reported by Exygen have been judged usable for the purposes o f the project. hr addition, 13 river-water samples and two blanks were submitted to Environmental Standards Incorporated o f Valley Forge, Pennsylvania, for quality assurance review. Results o f the additional quality assurance review also indicated that the quality o f the data is acceptable and qualification o f the data was not warranted. nverresults.doc Nov. 19,02 Wilmington.

The sampling investigation was designed to meet three main objectives: o Characterize background C-8 concentrations in river-water upstream o f the facility. Q Assess C-8 concentrations in river-water along the facility reach, O Evaluate C-8 concentrations in river-water downstream o f the facility. Ohio River water upstream o f the facility, along the facility, and downstream of the facility was sampled during this investigation. In total, 49 river-water samples were collected, including two duplicate samples. At selected sampling areas, as many as three river-water samples were collected along a single transect across the river and as many as three depths were sampled (dip, mid-column, and bottom). All river-water samples were , analyzed for C-8 in accordance with the Standard Operating Procedure approved by the GIST and the Quality Assurance Project Plan (DuPont, 2002e). During the same time period that the river-water was sampled, effluent from Outfall 005 was also sampled to evaluate dispersion downstream of the outfall. Historically, Outfall 005 has shown the highest concentrations o f C-8 and discharged a larger volume of effluent compared to the other outfalls and outlets at the Washington Works Facility. However, the C-8 concentration at Outfall 005 has been steadily decreasing in 2001 and 2002 following the installation o f a carbon adsorption treatment system in the flouropolymers process.

Two locations were sampled. One sampling location was positioned in the river near die point where the ravine originating at the I landfill discharges surface-water into the river. The other sampling point was located approximately 1000 feet downstream o f the first location. All samples were collected near the shoreline (approximately 100 feet east o f the shoreline). Dip mid mid-column I samples were collected at both locations. In total, five river-water samples were collected, including one duplicate sample. All river-water samples were analyzed for C-S in accordance with the Standard Operating Procedure approved by the GIST and the I Quality Assurance Project Plan (DuPont, 2002e), Sampling information and C-8 results for the Ohio River water sampled near the Letart T,andfill are summarized in Table 1 and are presented graphically in Figure 2. At each 1 transect location, a summary table o f C-8 results is shown in Figure 2.
