Research Project Summary: PCB TMDLs, Pollution Minimization Plans and Source Trackdown in Camden City

A PCB Pilot Source trackdown study was performed in the sewer collection system of the Camden County Municipal Utility Authority (CCMUA) as part of a PCB TMDL. The goals were to evaluate the most appropriate sampling and analytical techniques for tracking down PCB contamination to the MUA collection system and to identify potential upland sources. Innovative field and analytical methods were evaluated including the use of PCB analytical Method 1668a to attain high sensitivity and low detection limits; the quantitation of over 124 separate PCB congeners as a mean to identify unique source signatures through pattern recognition; the use of passive in-situ continuous extraction sampler (PISCES) for sample integration over protracted time periods (14 days); and the use of electronic data collection systems interfaced with a geographic information system (GIS). PCBs were found at all sewer locations (i.e., both urban and suburban) and in all sampling media potentially from varied sources (i.e., as indicated by differences in PCB congener profiles between waste streams).Series: Research Project SummaryPurpose: to report on a PCB source trackdown study performed in Camden, New Jerse
