THE USE OF A RAPID FIELD SCREENING METHOD TO IDENTIFY IMPACTED MEDIA AND POTENTIAL HUMAN EXPOSURE PATHWAYS AT A FORMER DRY CLEANING FACILITY

The South Carolina Department of Health and Environmental Control is tasked with the prompt investigation and assessment of sites that participate in the Drycleaning Facility Restoration Trust Fund. The investigation and assessment addresses the nature and extent of the contamination and includes a determination of potential human exposure pathways. The AQR Color-Tec® method for detection of Total Chlorinated Volatile Organic Halocarbons is being used as a rapid field screening method to delineate site contamination and to select soil and groundwater samples for analysis by a South Carolina certified laboratory. The case study demonstrates how the rapid field screening helps to define a contamination plume and impacted drinking water wells. The data derived from the field screening may also be used to assist with the selection of permanent monitoring well locations that will be used in groundwater monitoring and remedial work.
