Description Polychlorinated biphenyl (PCB) concentrations were sampled in edible fish tissue from Ward Lake (Thurston County) and the lower Elwha River below Lake Aldwell. The objective was to assess PCB concentrations to determine if one or both of these waterbodies should retain "water quality limited" (i.e., 303(d) list) status due to PCBs.

PCB Aroclors 1254 and 1260 were detected in all samples at concentrations from 3 to 12 ug/kg, above the National Toxics Rule criterion of 1.4 ug/kg. Therefore, it is recommended that both Ward Lake and the lower Elwha River be included on the 303(d) list for both PCB-1254 and PCB-1260.
