The C Street Landfill is just west of downtown Shelton and U.S. Highway 101. The Landfill was actively used as a dumping site for various industrial, municipal, and other waste for much of the 1900s.


In 2015, the Washington State Department of Ecology entered into an agreement with the City of Shelton to provide funding for the cleanup of the C Street Landfill through the Toxics Cleanup Remedial Action Grant. The agreement requires the City of Shelton to complete a remedial investigation and feasibility study, and submit a draft cleanup plan to the Department of Ecology.

Aspect Consulting of Bainbridge Island, WA was contracted to conduct the initial assessments and remedial investigation in June of 2015. The purpose of the in-depth study is to find out what needs to be cleaned up and where, including:

  • Determining site features like groundwater flow and soil type
  • Defining the type and extent of contamination
  • Assessing potential effects on human health and the environment
  • Defining the goals for the cleanup
In October of 2018, the City Council authorized an amendment to an agreement with the Washington State Department of Ecology to increase funds received from the state by $600,000 for the C Street Landfill Cleanup. The City is required to contribute a 25% match to the project budget on the additional funds. This additional funding increases the total project budget from $288,666.67 to $1,086,666,67.
