' TO : CL. KP. Campbell - Pensacola Tuck Dean - Pensacola Wee have completed the analysis of the exchange water sample #=2DB4 and I have included with this memo a Xeroxed copy of the complete run calculations and calibration curve. - Three 250 ml aliquots were taken from the 5 pint bottle and analyzed directly after extraction with hexane and concentration tix a: specif ic volume. Sample #201-1 was taken prior to shaking the- bottle vigorously, samples #201-2 and #201-3 after. The material extracted is as they reported -Aroclor 1254. Their . reported concentration of 274 ppb agrees well with our duplicate analysis, #201-2 and #201-3, which were 270 ppb and 269 ppb, respectively. In sample #201-1, we found 17.2 ppb Aroclor 1254 indicating that most of the Aroclor 1254 is adsorbed by the particulate matter present. .i .' . '* '. Wee-also have received the fish samples and the other water samples which we talked about. We analyzed one of the larger Bluegills. (65.37g) and found 133 +2 ppm Aroclor 1254. Wee will report the results of our analysis of the other samples ass soon as they are completed. \ dh ISicl.. Scott Tucker IN'IO REV. 11-65 DSW 433739 STLCOPCB4086847
