The Consent Order identified a series of requirements and tasks to be performed by the parties to determine whether there has been an impact on human health and the environment as a result of releases of ammonium perfluorooclanoate (C-8), CAS Number 3825-2$-!, to the envinauaetit 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 asses? the presence and extent of C.'S in drinking water, groundwaier and surface water ot and around the Washington Works facility and the Local, Letart and Dry Run Landfills. An additional component of the Consent Order relates to the West Virginia National Pollutant Discharge Elimination System (WV NPDES) pennit sampling requirements. In this portion of the Consent Order, specific outfalls and outlets (outfalls) are to bs sampled monthly for C-8 by DuPont. Pursuant to Attachment A of the Consent Order, three tasks were performed by DuPont and evaluated by the GIST, Tasks A, B, and C. Task A: Groundwater Use and Well Survey/Groitttdwater Monitoring was completed (DuPont, 2002a; 2002b). Task B: Assessment ofBxistmg Groundwater and Surface Water Monitoring Data included compiling of historical C-8 data, monitoring all wells at the landfills and developing a Groundwater Monitoring Plan (GMP) for the Washington Wories facility. The first part of the task, the historical C-8 data compilation report was submitted to the GIST for evaluation (DuPont. 2002c). The second part of this task, monitoring C-8 in groundwater at the landfills, began in December 2001, and was performed monthly for four months and quarterly (hereafter. The third part oftfae task, developing a GMP for the Washington Works facility, was submitted to the GIST (DuPont, 2002d). Groundwater sampling at the Washington Works facility began in January 2002, and was conducted monthly for four months and quarterly thereafter. Task C: Plume Identuication/Groundwater Assessment was also completed (DuPont, 2003). This report presents the results of the 3"' quarter (3Q03) C-8 surface water and groundwater sampling that was performed during July and August 2003 at the Washington Works facility, and the Local, Letart, and Dry Run Landfills. 3Q03 6W.SWMR.aoe Oct. 14.03 Wilmington, OE ASH026483 EID779765 EID779765 Surface Water And eroundwaier Monitoring Report_____________C'8 Analytical RepOlrtIng 2.0 C-8 ANALYTICAL REPORTING The analytical method, method detection limit, and laboratory utilized for C-8 analysis have changed over time. Prior to 1991, DuPoot performed C-8 analysis at the DuPont Experimental Station in Wihningtoii, Delaware. In 1991, when the RCRA Verification Investigation was conducted, the analysis was contracted to the CHzMHill Laboratory in Montgomery, Alabama. Both labs used a Gas Chromatography/Electron Capture Detector (GC-ECD) based analytical method with detection limits for C-8 that ranged from 0.1 to 1.0 ug/L CHbMHill conducted C-8 analysis for DuPont into the fall of 1998 when the laboratory ceased operation. The C-8 analytical work was transferred to Lancaster Laboratories, Lancaster, PA, in March 1999. Lancaster Laboratories contnmed to conduct C-8 analysis using GC-ECD for DuPont until October 2001when development and testing was completed on anew analytical method developed by Exygen Research, Inc. (Exygen; located in State College, PA) that utilizes Liquid Chromatography/Tandem Mass Spectrometry (LC/MS/MS). DuPont adopted the regular use of LC/MS/MS for C-8 analysis in water in November 2001 and Exygen was contracted to perform the analyses for DuPont. Exygen reports C-8 results for the laboratory replicate of each field sample. These results are evaluated for precision by comparing the field sample result to the corresponding laboratory replicate result. Q If both results are less than the jpracti'cal quantitation limit (PQL), the replicate sample for that analyte is considered to have passed the precision criteria. 0 If one or both results are between one and 6ve times the PQL, the replicate is considered to have met the precision criteria if the two results differ by less than the PQL. 0 If one result is less than the PQL and the other is not, and if the (wo results differed by a value less than me PQL, the replicate is said to have met the acceptance criteria, Q If both results are at least five times the PQL, the replicate is considered to have met the criteria if the relative percent difference (RPD) between the two results is less than or equal to 20%. The KPX> is the absolute value of the difference of two measurements divided by their average. When the precision criteria outlined above are met, Exygen reports the average of the field sample and lab replicate results reported by the laboratory. If criteria for precision are exceeded, Exygen reports the higher of the sample and lab replicate results. Finally, when one result (from the sample/lab replicate pair) is above the PQL and one below, the result that is above the PQLs is reported. C-8 results are recorded in the Corporate Environmental Databa$e (CED) and are reported as PC-143 for consistency with historical results. An aliquot of each field sample is also analyzed as a matrix spike (MS). Results of the MS analysis are used to assess accuracy. The MS recovery value must fall between 70 to 3Q03GW.8WMR.doc Ocfc 14,03 2 Wilrmtigtont DE ASH026464 EID77&766 EID779766 Surface Water And Grtnindwatel- Monitoring Repwt ____... _,...... ^'^ ^r>a^caj^ePPr*>lnl9 130%, unl<!S$ the sample concentration is at least four times the amount spiked.

All data packages generated by Exygen are reviewed in-bouse for compliance with the laboratory Standard Operating Procedures (SOP) and data usability, using the checklist provided in the QAPP. Results of the in-houss review indicate that data reported by Exygen have been generated m compliance with the laboratory SOP, with few exceptions as noted in the individual review summaries.

On August 15,2003, six outfalls were sampled for C-8 (001,002,003,005,007, and 105). All of these outfalls collect process water and stormwaterrunoEf. No changes to routine sampling protocols or other observations were recorded in the field notes during this sampling event. Monthly sampling of these outfalls is required by the WV NPDES permit No. WV0001279. The locations of these outfalls are shown in Figure 1.1. Groundwater sampling 'was attempted at 12 monitoring wells between August 25 and 26, 2003. Monitoring wells N13-MW01 and P08-MW01 were not sampled during this sampling event because the wells were dry. No other changes to routine sampling protocols or other observations were recorded in the field notes during this sampling ^ event. j4; fa addition, groundwater from six production wells was sampled on August 11,2003. Sampling of these wells was done according to routine sampling protocols. A combined groundwater sample representative of all the wells in the DuPont-Lubeck Well Field, labeled West Wellfield 1, was collected on August 11,2003 and analyzed for C-8. Sampling of this well field on a monthly basis began in December 2001 and continued through April 2002, and is now sampled quarterly. The locations of the monitoring and production wells sampled arc shown on Figure 1.1. This figwre also shows the location of the DuPont-Lubeck Well Field (bat was sampled. A groundwater elevation map for 3Q03 was not generated because of the limited data set. However, the groundwater elevation map for February 2002. the most recent groundwater sampling event where almost all site wells were included, is shown in Figure 1.2. Table 1.0 gunatnarizes the well construction and groundwater elevation data for the monitoring wells. Table 1.1A and Table I.1B provide the C-8 analytical results for surface water and groundwater, respectively. For each sampling point listed in the tables, historical data is summarized with the most recent results listed first.
