Description The Department of Ecology conducted seasonal monitoring for toxic contaminants in the Spokane River at the eastern Spokane Tribal boundary during 2015 – 2016. Toxics monitoring was conducted to provide recommendations for establishing a long-term monitoring program for the site.

Surface water and suspended sediment samples were taken during the three major hydraulic river regimes: spring high flow, summer low flow, and winter moderate flow. Samples were analyzed for PCBs, PBDEs, dioxins/furans, and metals (cadmium, copper, lead, and zinc). Three collection and extraction techniques were used to ensure detection of PCBs and PBDEs in surface water: CLAM (Continuous Low-level Aqueous Monitoring device), XAD-2, and liquid-liquid extraction of composite samples. Suspended sediments were collected with sediment traps.

Tables C-1, C-2, and C-3 are linked above as a Zip file.
