Description The objectives for this study were to make the first direct determination of PCDD/PCDF concentrations in Columbia River water, obtain a preliminary estimate of loads to Lake Roosevelt, and provide data to the Water Quality Program and EPA to assist in refinement of the Columbia River total maximum daily load (TMDL) for 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD). The field work was coordinated with an extensive Environment Canada study of water quality in the border reach of the Columbia River which included analysis of SPM samples for PCDDs/PCDFs.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
