All sediments extracted contained heavier EC/GC active materials however, the retention times and general peak shapes did not exactly match the EC fingerprints of either Aroclor 1254 or 1260 In two cases, OR Log Nos. 77 and 78, significant amounts of the heavier materials were present with respect to the Aroclor 1242 content. These heavier materials are most probably a mixture of Aroclor 1254 and 1260 whose Isomer distribution has been altered OR Log No. 77 W.G.K. Sediment Samples Sample Identlflcatlon Date ..."
