|Description||Between 2003 and 2007, the Department of Ecology conducted a series of water quality studies to assess sources of PCBs in the Washington section of the Spokane River. The lower part of the river flows through the Spokane Tribe of Indians reservation. The Spokane Tribe has adopted water quality standards for their reservation.
PCBs were analyzed in river water, industrial and municipal wastewater effluents, stormwater, suspended particulate matter, bottom sediments, and fish tissue.
A PCB loading analysis indicated large reductions (>95%) would be required for all sources to meet the Spokane tribal standard.
The report presents recommendations for a comprehensive toxics control strategy.
