Well locations are shown on Figure 2. (D)=duplicate sample. <br /> 2. Samples were analyzed for volatile organic compounds using U.S. Environmental Protection Agency Method 8260B. <br /> Results are reported in micrograms per liter(pg/L). Only detected constituents are shown in the table. <br /> PCE =tetrachloroethene, TCE=trichloroethene, C12DCE =cis-1,2-dichloroethene, T12DCE=trans-1,2-dichloroethene, <br /> 12DCA= 1,2-dichloroethane, 11 DCE = 1,1-dichloroethene, < = less than the reporting limit shown, na = not analyzed, <br /> J =estimated value below the reporting limit but above the method detection limit, and U = result qualified as not detected <br /> because the reported concentration is less than five times the concentration of the same constituent in an associated blank sample. <br /> Page 4 of 4 <br /> I:\130000 3290\Archive\13290-178 <br />
