Spokane River: Contaminants and Health


Public health risks

Public Health Risks

  • Chemicals and Heavy Metals

    • PCBs

    • PBDEs

    • Dioxins/Furans

    • Metals

  • Biological Hazards


1 pcbs polychlorinated biphenyls

1. PCBs (Polychlorinated Biphenyls)

  • Spokane River does not meet WA human health criteria for PCBs in edible fish tissue

  • Sources and pathways to the Spokane River

    • City of Spokane stormwater (44%)

    • municipal and industrial discharges (20%)

    • and Little Spokane River (6%)

    • PCB loading from Idaho at the state line (30%)


2 pbdes polybrominated diphenyl ethers

2. PBDEs(Polybrominated Diphenyl Ethers)

  • Chemical additives used in everyday household products as flame retardants

  • Sources and pathways to the Spokane River

    • Can leach out of manufactured items and enter the air, soil and water

    • Has been detected in sediment, storm water, and sewage from residential and industrial sources


3 dioxins furans

3. Dioxins/Furans

  • Can be released into the air, soil, and water. Fish tissue sampling in the Spokane River showed elevated levels

  • Sources and pathways to the Spokane River

    • Byproduct of burning municipal waste, sludge, medical waste, and wood and cement kilns

    • Byproduct of manufacturing herbicides and pulp/paper products


4 metals

4. Metals

  • Lead, arsenic, cadmium and zinc are released as part of mining, milling and ore processing

  • Sources and pathways to the Spokane River

    • An estimated 100 million tons of mine wastes released in river from the Upper Coeur d’Alene Basin in Idaho.

    • Contaminants traveled downstream, moved through Lake Coeur d’Alene and deposited in the Spokane River.
