Public water supplies located as far as three and a half miles upstream of the DuPont Washington Works facility and 53 miles downstream have been included in the sampling events. Based on the very low C-8 concentrations measured at the various public water supplies, the number and frequency of sampling events at the public water supplies was reduced by the Groundwater Investigation Steering Team in May 2002. Currently, three public water supplies, Lubeck (West Virginia), Tuppers Plains (Ohio) and Little Hocking (Ohio), are sampled on a quarterly basis. f The finalized C-8 results for the 3Q02 and 4Q02 sampling events conducted at Lubeck (West Virginia), Tuppers Plains (Ohio) and Little Hocking (Ohio) are presented in Table 1. For the public water supplies that have been sampled more than once, results are presented with the most recent sampling event listed last. Figure 1 shows the locations of all the public water supplies sampled along the Ohio River. 1 The next sampling event at these Public Water Supply Wells is scheduled for 1Q2003. Please contact me at (302) 992-6820 if you have any questions. ] i Sincerely, lI Q J a m Q i Andrew S.
