A PCB source trackdown study was performed in Camden, New Jersey using the sewer collection system of a municipal utility authority (MUA). Sampling and analytical techniques were developed to identify PCB sources using innovative desktop, field and analytical methods including high resolution gas chromatography and mass spectroscopy; the quantitation of 124 separate PCB congeners for source signatures; the use of passive in-situ continuous extraction samplers (PISCES); and the use of electronic data interfaced with a GIS system to geographically isolate potential sources. In addition, PCB immunoassay analyses (ELISA) of street soils were carried out near storm drains in front of suspected facilities. These source identification methods were developed to support Pollution Minimization Plans (PMP), which are permit requirements for discharger facilities in New Jersey, Pennsylvania and Delaware as part of the Delaware Estuary PCB-TMDL. The PMP rules require dischargers to actively seek out, and reduce, PCBs on their facilities footprint which might get into the MUA collection system. This can be problematic, however, for a county-wide MUA with hundreds of miles of pipes and numerous undefined point and non-point sources (i.e., Camden City is a combined sewer outfall (CSO) area where storm run-off can collect PCBs and other contaminants then mix with sewerage in pipes prior to treatment).
