Crown Cleaners, Orange City, Florida
Description
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| PCE Drycleaning operations were conducted at this facility from 1989 until mid-2003 when it was converted to a dry drop-off facility. The facility is located in a shopping center in a retail commercial/residential setting.
Contaminant source areas are the soils beneath the floor slab where the drycleaning machine was formerly located and the area around the service door. A sinkhole lake is located approximately 1000 feet north-northwest of the site. Remediation Status: Site closed |
