SITE BACKGROUND

Contaminants from historic mining practices in Idaho’s Coeur d’Alene Basin washed downstream and settled in soil and sediment along some Spokane River beaches. 

The U.S. Environmental Protection Agency (EPA) conducted studies of the mining contaminants in the Coeur d’Alene Basin and began a wide-spread cleanup of the Bunker Hill Mining and Metallurgical Superfund Site. As part of the EPA study and studies Ecology conducted, 9 beaches in Washington were cleaned up, including Harvard Road.

The Harvard Road site covers less than 1 acre and lies along the northern bank of the Spokane River. It is almost 3 miles west of the Idaho state line and immediately west of the Harvard Road Bridge. 


CONTAMINATION

The mining-related contaminants include arseniccadmiumlead and zinc.


CLEANUP

Cleanup activities were completed in 2008:
  • Contaminated sediments along the upper portion of the Spokane River bank were removed, and the area was backfilled with clean sand and gravel. Contaminated sediments were disposed of at an approved landfill.
  • A protective cap of clean sand and gravel was placed on the lower portion of the river bank where contaminants were not removed. The cap eliminated the exposure pathway for humans and wildlife.
  • A new gravel boat launch was installed.
  • Gravel mix was placed at important fish habitat locations.
  • Signs and physical barriers, such as fences and boulders, were installed to define the launch ramp, parking, and pedestrian access areas.
Ecology will conduct a periodic review at least every five years following site cleanup, as required by the Model Toxics Control Act. The purposes of the review are to evaluate site conditions and ensure the cleanup continues to protect human health and the environment.
