State Coalition for Remediation of Drycleaners Site Profiles
Harbour Place Cleaners, Jacksonville, Florida
Description
|
PCE drycleaning operations began at this site in 1991. Sometime prior to 2000, the facility switched from PCE to Rynex, a glycol ether-based drycleaning solvent. In 2008, the facility began using DF-2000, a petroleum drycleaning solvent.
The identified contaminant source areas at the site are the soils beneath the floor slab near the drycleaning machine and the area outside the service door where wastewater was reportedly discharged to the pavement.
The facility is located in a bay in a shopping center in a mixed retail commercial/residential setting.

Lessons Learned
Conventional soil sampling found little contamination. A modified active soil gas sampling survey produced a soil gas sample with a VOC concentration of 50.7 milligrams per cubic meter. |
