State Coalition for Remediation of Drycleaners Site Profiles
Dryclean Pro, Palm Beach Gardens, Florida
Description
|
PCE drycleaning opertions were conducted at this site from 1993 to January 2005. The contaminant floor slab was the drycleaning machine. The facility is located in a strip mall in a retail commercial/residential setting. Remediation Status: Site closed |

Lessons Learned
The high PCE concentrations found in groundwater were in samples collected at the top of the water table in the near vicinity of the drycleaning machine. During assessment activities, soil borings in the contaminant source area are generally deepened into the top of the water table where groundwater samples are collected. Generally, these groundwater samples have the highest contaminant concentrations of all the groundwater samples collected during assessment activities. |
