CURRENT STATUS

The Washington Department of Ecology (Ecology) held a public comment period between August 5 and September 3, 2019 for a Remedial Investigation (RI) and Feasibility Study (FS), cleanup documents required by legal agreement, Agreed Order DE 6829.  No comments were received. The RI/FS are now final.

BACKGROUND

Contamination

The Park Laundry property is located at 122 N. Main Ave. in Ridgefield, Washington.  The property was used as a laundry and dry cleaners from about 1965 to1977.  During that time, two chlorinated solvents, tetrachloroethylene (PCE) and trichloroethylene (TCE) associated with dry cleaning were released to the environment and contaminated soil and
groundwater. 

In 2008, the Environmental Protection Agency (EPA) completed an investigation that showed soil and groundwater were contaminated with elevated levels of the chlorinated solvent tetrachloroethylene (PCE), and recommended further investigation.  In 2009, Ecology entered into Agreed Order DE 6829 with Union Ridge to determine the full extent of contamination both on and off-property.

Further sampling found PCE and an additional chlorinated solvent, trichloroethylene (TCE) plus their breakdown products on the property and on two lots north of the property above state cleanup levels in soil and groundwater.  In 2012, Union Ridge began a vapor intrusion study with Ecology and Washington Department of Health oversight.

2012/2013 Vapor intrusion study results

In 2012, Union Ridge sampled indoor air and soil gas from commercial and residential buildings that sit over the contaminated groundwater. In 2013, they re-sampled the same buildings for comparison. Outdoor air was also sampled.  Both rounds of sampling showed that the buildings are not likely affected by vapor intrusion. Sampling did find other chlorinated solvents in some buildings. However, tests showed these chemicals are likely coming from products used or stored in the buildings and not from the site.

Vapor intrusion is not a pathway of concern. It could be a problem if a building is constructed over the source area, which is the area of the site with the highest concentrations of contamination.  

Site health risks

Chlorinated solvents are suspected to cause cancer in humans.  Possible exposure to these chemicals in groundwater or vapor are limited to open excavation areas within the source area.



NEXT STEPS

The Cleanup Action Plan (CAP) will be the next document available for public comment.
