State Coalition for Remediation of Drycleaners Site Profiles
Renaud Executive Cleaners, Winter Haven , Florida
Description
|
This is an active PCE drycleaning operation that has been open since the mid 1960s. Minor solvent spills associated with changing filters and moving a drum of PCE had been reported. The facility is located in a strip mall in a mixed retail commercial/residential setting. A lake is located approximately 800 feet south of the facility. Contaminant source areas are the soils beneath the floor slab in the vicinity of the drycleaning machine and the area outside the service door. Remediation Status: Site closed |
