SOURCE IDENTIFICATION STUDIES

2002-2003

Asiatic Clams

Very low PCB concentrations were detected in Asiatic clams and only from sites in the Blue River. No PCBs were detected in clams collected from the three sites in Indian Creek. Like fish, higher chlorinated PCBs were found in clams upstream of KCP discharges, while PCB-1242 was only detected in the clams detected downstream of KCP.

Semipermeable Membrane Devices (SPMDs)

Extracts of low-chlorinated PCBs resembling Aroclor 1242 (identified as Aroclor 1248 in March 2003) were found in SPMDs at all sites where they were placed in the storm drain network feeding Outfall 002.
