Description The Washington State Department of Ecology placed Chambers Creek on the 1998 303(d) list for PCB concentrations in edible shellfish tissue that exceeded the EPA National Toxics Rule criterion for human health. Because EPA recently revised their human health criterion for PCBs upward from 1.4 ug/Kg to 5.3 ug/Kg (wet weight), Ecology did more intensive sampling to determine if the 303(d) listing was still warranted. Results showed total PCB concentrations ranged from 3.1 to 3.9 ug/Kg. Therefore, it is recommended that the 303(d) listing for Chambers Creek be removed.
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.
