Description The lower Palouse River was listed as impaired (Category 5) on Washington’s Water Quality Assessment for 4,4’-DDE, heptachlor epoxide, alpha-BHC, dieldrin, and PCB-1260 in edible fish tissue. Based on a review of historical data and results of an intensive fish tissue survey, Ecology recommends that 4,4’-DDE, heptachlor epoxide, and alpha-BHC be reclassified to meets standards (Category 1), and a Total Maximum Daily Load is proposed for dieldrin and PCBs. The implementation plan calls on monitored natural attenuation and stormwater and agricultural best management practices to reduce dieldrin and PCB levels and bring the river into compliance with water quality standards.
