Soil Vapor Extraction (SVE) at Six Drycleaner Sites, Various Locations (continued)
Regulatory Requirements/Cleanup Goals:
Soil cleanup target levels were not specified for any of the six sites. For two sites (Cox’s One Hour Martinizing and
Sunshine Laundry), the goal of the cleanup was to remove the contamination mass from the source area and stop
contaminant migration.
Results:
At two sites (ABC Cleaners and Wash ‘N Dry Cleaners), SVE failed due to high water levels in the soil
At Art’s Dry Cleaners, PCE concentrations in the soil were reduced from 1,000 to 0.13 mg/kg
At Cox’s One Hour Martinizing, PCE concentrations in the soil were reduced from 25,000 to 5 mg/kg, and
approximately 170 gallons of PCE were removed after one year of operation. The concentrations showed a rebounded
within the first few months of operation, but decreased afterward. The SVE system removal rate peaked at
approximately 12.4 lbs per day within first six months of operation, but later decreased to 0.4 lbs per day.
No information was provided for the other two sites (Crain Fabric Care Center and Sunshine Laundry).
Costs:
Design and implementation costs for SVE systems were provided for two sites (Cox’s One Hour Martinizing and Art’s
Dry Cleaners) and ranged from ranged from $18,000 to $52,000
O&M costs were provided for two sites - Cox’s One Hour Martinizing - $3,500 for 2 years, and Crain Fabric - $400 for
mobilization and $1,140 per visit for laboratory work.
Cost information was not provided for the other sites.
Description:
SVE was conducted at six drycleaner sites contaminated with chlorinated organic compounds from drycleaning operations.
Cleanup goals for soil were not provided for any of the sites. Two sites reported that SVE reduced PCE concentrations in
the soil from 25,000 to 5 mg/kg, and from 1,000 to 130 mg/kg, respectively. At two sites, SVE failed due to high water
levels in the soil. No information on the results of SVE at the other two sites. Reported design and implementation costs
for the SVE systems ranged from $18,000 to $52,000. O&M costs at one site was $3,500 for a period of 2 years.
