SITE BACKGROUND

The site is located approximately seven miles southwest of Spokane and one mile southwest of the town of Marshall.

Because parties responsible for contamination at the site are unable or unavailable to pay for cleanup, the Washington Department of Ecology (Ecology) is leading and funding cleanup.

The landfill has two waste disposal areas:

  • The 25-acre main landfill operated from 1970 through 1990. After closing, it was covered with a sand layer.
  • The 5-acre landfill operated from 1980 through 1984. A passive gas venting system and compacted clay cap were installed after it closed. The cap appears to have failed in spots, however, and some waste is exposed.

A landfill owned by Spokane County is next to the site, but current information doesn’t show contamination coming from that landfill so it is not part of the cleanup.


CONTAMINATION

Volatile organic compounds (VOCs); gas-, diesel- and oil-range hydrocarbons; metals, including arsenic, cadmium, copperlead and mercury; and pesticides and herbicides have been reported during previous soil and groundwater investigations at the site. 


CLEANUP

From 1989 to 1991, Marshall Landfill, Inc. installed 17 monitoring wells to investigate soil and groundwater contamination after it was detected in nearby residential wells in the late 1980s. They sampled groundwater quarterly from 1993 to 2011, under Spokane Regional Health District requirements.

In 2013, Ecology received funding to do a remedial investigation and feasibility study to determine the extent and locations of contamination and evaluate cleanup options.

The draft Work Plan for the Remedial Investigation and Feasibility Study and Public Participation Plan were available for public comment February 23 to March 5, 2015. Ecology provided background about the site, the current status, and proposed work during a presentation at a public meeting in Marshall on March 5, 2015.Ecology responded to public comments before finalizing the work plan.

The Remedial Investigation Report and Feasibility Study were available for public comment July 2 - August 1, 2018. We received no comments, and are now developing the cleanup action plan.
