Site Background

From approximately the early 1900s to 1960s the site was used for residential purposes and had an older house on the property. In the 1960s, the house was torn down and the site was vacant until the mid-1980s when the current owners purchased the property to operate a dry cleaning business called Mr. A's Dry Cleaners. The site was used for this purpose until December 2006. Mr. A's Dry Cleaners was vacated at that time to prepare for the Brownfields assessment and future sale of the property.

Site Investigation Process

Through the Brownfields program, DEQ contracted with Terragraphics to perform a Phase I Assessment on the property. The Phase I Assessment revealed significant environmental concerns on the property so DEQ again contracted with Terragraphics to perform a Phase II Assessment. The Phase II Assessment consisted of collecting soil samples from nine boreholes, installing two upgradient and one downgradient monitoring well, collecting downgradient and upgradient ground water and soil samples, installing nine subslab vapor points, and issuing a report that summarized activities and also compared cleanup methodologies and costs. The report was finalized June 4, 2007, and indicated there was dry cleaning solvent contamination in the soil and ground water, as well as dry cleaning solvent vapor intrusion into the building.

Site Cleanup

The owner entered DEQ’s Voluntary Cleanup Program (VCP) and contracted with Terragraphics to create a remediation work plan and implement cleanup. The work plan was approved and finalized February 11, 2008, and cleanup began the same month. Cleanup consists of ozone sparging and vapor extraction.

Redevelopment Plans

The site has been redeveloped; Don Aslett's Cleaning Center is open for business.
