Description The Washington State Department of Ecology studied DDT in the lower Mission Creek basin during 2003 to address federal Clean Water Act section 303(d) listings and develop a TMDL assessment.

DDT was analyzed in orchard soils, bed sediments, suspended particulate matter, surface water, and groundwater. Sampling found that orchard soils contain substantial amounts of DDT. In streams, DDT loads will require reductions of 69-98% to meet the target criterion of 1 ng/l total DDT.

The report includes DDT load estimates, target loads, load allocations, and recommended load reductions.
