Spokane River - Upriver Dam PCBs Sediments Site

SITE BACKGROUND

Ecology and Avista Development, Inc. are cleaning up a segment of the Spokane River known as the Upriver Dam PCBs Sediments Site. The site is divided into two projects. Deposit 1 begins directly behind Upriver Dam in the city of Spokane and continues east for approximately 3.6 acres. Deposit 2 is a small 0.25-acre area near Donkey Island in an unincorporated area. Sediments at both project locations are contaminated with Polychlorinated Biphenyls (PCBs). Cleanup is necessary, because PCBs build up in the fatty tissues of humans, fish and animals and may cause harmful health effects.

Benefits of this Project

  • Cleanup improves the health of the Spokane River.
  • These restoration projects reduce contamination in the environment.
  • Reducing contamination provides a safer environment for children, adults, and wildlife who may use these areas.
