State Coalition for Remediation of Drycleaners Site Profiles
Camarota Cleaners, Mechanicville, New York
Description
|
Dry cleaning operations were performed in a one story stand alone building. From 1970s to 1991, dry cleaning operations utilized PCE as the dry cleaning agent. The site is located within an urban residential area. Remediation Status: In active remediation |

Lessons Learned
Trees found to be taking up PCE, but limited reduction in groundwater concentrations after two years. Groudwater up take rates will increase as the trees mature, which may reduce groundwater concentrations. |
