The Consent Order identified a seriesofrequirements and tasks to be performed by the parties (WVDEP, WVDHHR-BPH, and DuPent) in order to determine whether there has been any impact on human health and the environment as a resultofreleases of ammonium perfluorooctanoate (C-8), CAS Number 3825-26-1, to the environment from DuPont operations at the Washington Works 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 extentof C-8 in drinking water, groundwater, and surface water at and around the Washington Works Facility and the Local, Letart, and Dry Run Landfills. In addition, the Consent Order required sampling ofall surface or alluvial water intakes for public water supplies along the Ohio River in the area extending ten river miles downstream and one river mile upstream of the Washington Works Facility. The areas of investigation were to be expanded directionally,ifneeded, based on results obtained. `The Little Hocking Water Association well field (Little Hocking) is located in Ohio on the north sideof the Ohio River immediately across from Washington Works facility. Little Hocking provides drinking water to residences and businesses in Washington County, Ohio. Groundwater sampling at the Little Hocking was first conducted in December 2001. In January 2002, upon receiving groundwater results which displayed C-8 concentrations up to 7.66 ug/L at Little Hocking, the Ohio Environmental Protection Agency (Ohio EPA) was asked to join the GIST as a non-voting member on West Virginia issues. In addition, a Memorandum of Understanding was negotiated between the Ohio EPA and DuPont that outlined investigation activities in Ohio. Based on the initial C- results obtained for Little Hocking groundwater, re-sampling was required by the GIST. Additional groundwater sampling in January and February of 2002 confirmed that C-8 had impacted the groundwater at Little Hocking. In February 2002 DuPont offered to conduct a distance-phased groundwater well and water-use survey within a one-mile radial distance from the Washington Works Facility, across the Ohio River in Washington County Ohio to evaluate the extentofthe impact from C-8. The Ohio EPA accepted the offer. Between March 20and June 6, 2002, DuPont, through Potesta Associates, Inc. (Potesta), conducted the one-mile radius groundwater well and water-use survey in Ohio. This document presents the results of the survey: Q Section 2 provides information on C-8 analyses and analytical reporting.

Specifically, Sections 5, 6, and 10 present sampling protocols, sample and document custody procedures, and intemal quality control checks that were followed during the field sampling activities associated with the groundwater well and water-use survey.

During the Ohio one-mile radius survey groundwater was sampled from a total of six wells at two industrial facilities. At Kraton Polymers, groundwater from four monitoring. wells was sampled. At Price-Inland Industries groundwater was sampled from two pmooinnittso.ring wells. Table 3 provides the C-8 results for these non-residential sampling uses,Figure 1 shows the location of all samples included in Table 2 and Table 3. At each sampling point shown in Figure 1, the sample identification and C-8 concentration are noted. (C) or Sample identifications for (S), respectively. All other water samples from cisterns or springs are indicated by sample identifications (without notation) indicate water samples from wells. Sample identifications and C-8 concentrations colored blue indicate drinking water sources. Sample identifications and C-8 concentrations colored black indicate water samples that come from non-drinking water sources. Non-drinking water uses include livestock watering, gardening and any other non-human consumption water Appendix A provides the groundwater well and water-use survey results and includes details such as the following: 9 Name Q Address or physical description Q Phone number Q Date and time of water sample collection,ifcollected Q Typeof sample oO Wateruse Q Sample identification WOiHn-i1nrgeopno,nOtF.dJoucl. 31.02 000325 s erie Rau Survey 3nd C- Samping Reset Path Forward 4.0 PATH FORWARD Based on apreliminary evaluationofthe results for the one-mile radius sampling, DuPont and the Ohio EPA mutually determined that expanding the survey area to a two-mile radius was needed. DuPont has agreed to extend the survey to a two-mile radius as shown in Figure 2. All homes within the entire area within the two-mile radius, areas. "A", "B", and "C" will be surveyed. In area "B" all wells, springs, and cisterns will be sampled, regardless of use (drinking water, non-drinking water, or unused). In addition, all drinking water, non-drinking water, and unused wells, springs, and cisterns from residences located along Township Road 97 (located within area "C"), will be sampled. However, in area "A" and "C" wells, springs, and cisterns will only be sampledifthey are used as drinking water sources; non-drinking water and unused sources will not be sampled. On May 17, 2002, surveying in the expanded two-mile radius began. Upon completion ofthe surveying and water sampling and upon receiptof finalized results, a report documenting the results will be generated and submitted to the GIST and the Ohio EPA. Another path forward for the two-mile radius survey task is the quality assurance review. As indicated in Section 2.0, independent quality assurance reviewofdata packages is an ongoing activity. It is anticipated that data packages for the two-mile radius samples will be submitted to the validator. Results of the ongoing quality assurance will be summarized in a future report. hme ane Retain 000326 On. Radius Survey 3nd C-8 Samping Report References 5.0 REFERENCES DuPont. 2002.
