Sharon Cleaners, Saratoga Springs, New York

Historical activity that resulted in contamination.

Dry cleaning operations were performed in a one story stand alone building. From 1960s to 2001, dry cleaning operations utilized PCE as the dry cleaning agent. Since 2001, dry cleaning operations have utilized DF2000. The site is located in an urban commercial/residential area. A soil vapor extraction system was installed in March 2001 and operation for approximately 9 months. Vapor mitigation systems were installed in November 2009.

Remediation Scenario

Cleanup Goals:
  Protection of human health and environment. Compliance with New York State standards, criteria, and guidance.
Remedy Level:
  Full Scale Remedy


Ex Situ Vapor Mitigation

Why the technology was selected:
Could be installed quickly, achieve desired goals in a reasonable timeframe, and was cost effective.

Date implemented:
November 2009

Final remediation design:
Install vapor mitigation systems at three structures. Upgrade of basements due to poor condition of concrete floors prior to installation of vapor mitigation systems.

Other technologies used:
Basement upgrades to seal cracks and increase effectiveness of the vapor mitigation systems.

Cost to Design and Implement:
$112,000 for DEC costs after 2005.


Cost for Assessment:
  $211,000 for DEC costs after 2005.
Cost for Operation and Maintenance:
Total Costs for Cleanup:
