Drycleaner Site Profiles
Starcrest Professional Drycleaners, Sunrise, Florida
Description
|
Drycleaning using PCE was conducted at this site from March 1972 until May of 1995. The shopping center in which the drycleaning operation was located was razed in 1999/2000. Under a voluntary cleanup, approximately 20 inches of soil was excavated from beneath the floor slab of the bay that formerly housed the drycleaning operation. The former location of the bay that housed the drycleaning operation is now a parking lot for the new shopping center. Remediation Status: In groundwater monitoring |

1. A modified active soil gas survey is a good tool for locating contaminant source areas at drycleaning sites, particularly at sites where the building that housed the drycleaning operation has been razed and little is known concerning the former locations of equipment, waste storage areas and historical waste disposal areas. 2. Considerable contaminant mass was sorbed onto organic material in the organic-rich sand that occurs at 6-9 ft bgs. Removal of most of this material has resulted in substantial decreases in contaminant concentrations in groundwater at the site. |
