Olympia, Washington PCB and Pesticides Study
Listed in NASA Earthdata CMR
In June 1990, as part of Ecology's investigation of contaminants in Lake Roosevelt, a series of sediment and bottom fish samples were collected from Lake Roosevelt and vicinity for analysis of PCDDs and PCDFs.
Description
The impetus for this survey was the need to better understand the spatial distribution of these compounds as a result of their discharge by the Celgar bleached kraft pulp mill in Castlegar, B.B., approximately 30 river miles above the international boundary.
The results of these and other PCDD/PCDF analyses on Lake Roosevelt samples have been reported elsewhere (Johnson et al., 1991a, b,c). This report contains analysis of sediment and bottom fish samples for only PCB and DDE compounds (Johnson 1991). Six sites were studied in Lake Roosevelt between the international border and Grand Coulee Dam, one site each in the Spokane River and Rufus Woods Lake.

After recording the length and weight of each specimen, they were individually wrapped in aluminum foil, placed in polyethylene bags and stored on ice. The fish were analyzed as composites of five whole fish per sample. The metadata for this data was taken from the U.S. Environmental Protection Agency's Columbia River Basin: Biota Database Abstracts.
