Drycleaner Site Profiles
Former Dollar Cleaners, Lake Worth, Florida
Description
|
Drycleaning using PCE was performed at this facility for less than 19 months (1986-87). The facility is located in a small strip shopping center situtated in a mixed commercial/residential setting. A drainage canal is located approximately 75 feet southwest of the facility. The nearest public water supply well is located approximately 2000 feet southeast of the site. The contaminant source area is the soils beneath the facility floor slab in the vicinity of the drycleaning machine. |

1. Even though drycleaning was performed for less than 19 months at this site and site assessment occurred 13 years after drycleaning operations ceased, drycleaning solvent contamination in soil and groundwater still exceeded cleanup target levels. 2. It is likely that excavation related to installation of the SVE system piping aided in remediation of PCE in soils at the site. |
