Description In 2007-2008, the Department of Ecology monitored polychlorinated biphenyls (PCBs) and dieldrin at three wastewater treatment plants (WWTPs) and two abandoned landfills in the South Fork Palouse River watershed.

This study was to (1) establish whether the WWTP discharges exceed EPA human health criteria, and (2) assess landfills as sources of PCBs and dieldrin.

The findings indicate PCB reductions at all three WWTPs, and dieldrin reductions at the Pullman WWTP, are necessary. The soils/sediment and surface water samples from the two landfills contained the contaminants at relatively low levels.

Continued monitoring and limited pollution source tracking measures are recommended.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
