Columbia River Dioxin and Furan Study

The upper and lower reaches of the Columbia River have been well studied for TCDD/TCDF contamination if fish, a void in data exists for the middle reaches. Ecology responded by undertaking a survey of TCDD/TCDF in sportfish from eight stations in the Columbia River just above Chief Joseph Dam (Rufus Woods Lake) to McNary Dam (Lake Wallula) during May to November, 1990 (Serdar et al. 1991). Sportfish samples were also collected from the mouth of the Columbia River. A total of 187 individual fish were collected resulting in a total of 46 composite tissue samples analyzed for dioxins and furans.
