New City Cleaners

Remedial Investigation / Feasibility Study available for public comment

March 23, 2020 - April 22, 2020, 11:59 p.m.

We are inviting the public to comment on public documents for the New City Cleaners site.

A Remedial Investigation and Feasibility Study is now available for the New City Cleaners site, located at 747 Stevens Drive in Richland.

We invite you to review and comment on the following document:


The site has been operating as a dry cleaning business since the late 1940s. Since then, common dry cleaning chemicals, Stoddard solvent, a flammable petroleum mixture and tetrachloroethene (also known as PCE, perchloroethylene, and PERC) have been used at the site. Trichloroethene (TCE) is a common industrial solvent used to remove grease from metal. 

After the discovery of PCE in groundwater, four underground storage tanks (some containing petroleum products, some containing dry cleaning chemicals) were removed. Approximately 5,000 tons of contaminated soil was removed and disposed of offsite in an effort to control the source of groundwater contamination.  Bioremediation is a process that commonly uses oxygen or other chemicals to create conditions in the groundwater that help microorganisms grow. These microorganisms then breakdown contaminants such as PCE.

Groundwater samples continue to show that PCE and TCE remain a concern at the site. PCE is no longer used at New City Cleaners and has been replaced with an alternative safety solvent.
