| Short 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. (Also see abstract below) | |||

| Abstract | Long Description |
The Washington State Department of Ecology (Ecology) placed Chambers Creek on the 1998 303(d) list for polychlorinated biphenyl (PCB) concentrations in edible shellfish tissue that exceeded the U.S. Environmental Protection Agency (EPA) National Toxics Rule criterion for human health. The listing was based on bay mussels (Mytilus sp.) collected by Ecology in 1995 near the creek′s mouth on Puget Sound. Because the PCB concentrations were relatively low and 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. |
