General Information

Site Name and Location:		Denice Cleaners Coral Springs, Florida, United States
Description: Historical activity that resulted in contamination.		This is an active PCE drycleaning facility that has been in operation since 1985. Reportedly, in 1991 there was a spill of 5-10 gallons of PCE outside the service door of the facility during a solvent delivery. The drycleaning facility is located in a strip mall in a retail commercial/residential setting.

Contaminants:

Contaminants: Contaminants present and the highest amount detected in both soil and groundwater (please avoid giving ranges).		Contaminant Conc in GW Conc. in Soil 1,1-Dichloroethene 23 µg/L cis-1,2-Dichloroethene 3.9 µg/L Tetrachloroethene (PCE) 53 µg/L 920 µg/kg Trichloroethene (TCE) 4.0 µg/L Vinyl Chloride 1.0 µg/L
Other Contaminants Present: Indicates what other contaminants were found on-site
Deepest Significant Groundwater Contamination:		12 ft bgs
Plume Size:		80 ft x 60 ft x 12 ft

Site Hydrology:

Depth to Groundwater:		~ 5 ft bgs
Lithology and Subsurface Geology:		Fine- to medium-grained sand, surface-5 ft bgs; Weathered limestone, 5-8 ft bgs; Medium-grained sand, 8-15 ft bgs; Medium- to coarse-grained sand and limestone gravel, 15-20 ft bgs.
Conductivity:		105 ft/day ft/day
Gradient:		0.008 ft/ft

Pathways and DNAPL Presence:

Pathways:		Groundwater Soil
DNAPL Presence:		No

Vapor Intrusion Pathway:

Has the potential for vapor intrusion (VI) been evaluated?

No

Remediation Scenario:

Cleanup Goals:

Groundwater: PCE = 3.0 µg/L, TCE = 3.0 µg/L, cis 1,2-DCE = 70 µg/L, 1,1-DCE = 7.0 µg/L, vinyl chloride = 1.0 µg/L Soil: 30 µg/kg

Technologies:

Technologies Used:		Ex Situ: Soil Removal
Other technologies used:
Why the technology was selected:		The contaminated soil was located beneath an alley behind the facility and was accessible.
Date implemented:		October 29-30, 2001
Final remediation design:		Approximately 2.4 cubic yards of soil was excavated with a backhoe. The excavation was backfilled with limerock and the pavement was restored.

Results and Next Steps:

Results to date:		Contaminant concentrations in groundwater declined to below MCLs for three consecutive sampling events. A Site Rehabilitation Completion Report was issued on November 5, 2001.
Next Steps:

Costs:

Cost for Assessment:		$50,200
Cost to Design and Implement:		Soil excavation, disposal & site restoration: $ 16,100
Cost for Operation and Maintenance:		Groundwater Monitoring: $ 23,600
Total Costs for Cleanup:		$ 89,900
