Columbia River Dioxin Study
Listed in NASA Earthdata CMR
The Columbia River and segments of the Snake and Willamette Rivers are currently water quality limited due to the presence of elevated levels of 2,3,7,8-TCDD.
Description
As a result, U.S. EPA Region 10, established a Total Maximum Daily Load (TMDL) of 6 mg of 2,3,7,8-TCDD/day based upon state water quality standards applicable to the Columbia River basin and the volume of water in the Columbia River. The data set focused on one or two sampling locations in a specific segment of the river.
Criteria for choosing these locations were to: (1) sample at fishing sites, (2) collect organisms that are consumed by Native Americans and others fishing in the Columbia River basin, (3) collect organisms that are good indicators of contaminant levels in the river and of levels of contaminants that may be ingested by aquatic and terrestrial predators. There were six locations which sampled dioxin/furans, pesticides, polychlorinated biphenyls (PCBs), semi-volatiles, polyaromatic hydrocarbons (PAHs), mercury (Hg) by using rod and reel, electroshocking, setline and hoop and/or gill net.

The area of study is the Columbia River from Bonneville Dam to McNary Dam. Samples consist of composite between 3-8 samples and individual fillets. Crayfish will be handled in the same way as fish using baited traps.
Crayfish are represented as a composite of 30 organisms, following whole body analysis. Total dioxin and furan concentrations were determined by the laboratory as the sum of the individual congeners that were detected. The metadata for this data was taken from the U.S. Environmental Protection Agency's Columbia River Basin: Biota Database Abstracts.
