Drycleaner Site Profiles

Parisian Cleaners, Orlando, Florida

Description
Historical activity that resulted in contamination.

Active drycleaning facility since 1954. Commercial property. Used petroleum-operated drycleaning machine. No information regarding historic waste generation, management practices, or haulers before 1994.

Contaminants
Contaminants present and the highest amount detected in both soil and groundwater.


Contaminant Media Concentration (ppb) Nondetect

Remediation Scenario

Cleanup Goals:
  PCE--GW = 3 µg/L; Soil = .03 mg/kg(leachability);
TCE-- GW = 3 µg/L; Soil = .03 mg/kg(leachability);
Napthalene-- GW = 20 µg/L; Soil = 1.7mg/kg (leachability);
1,2,4 TMB-- GW = 10 µg/L; Soil = .3mg/kg (leachability);
1,3,5 TMB-- GW = 10 µg/L; Soil = .3mg/kg (leachability)

Technologies

In Situ Soil Vapor Extraction
 

Why the technology was selected:
Significant PCE soil contamination amendable to SVE technology.

Date implemented:
Start-up began-July 9, 2002 Construction begain in February 2002

Final remediation design:
Two vertical SVE wells. One was placed inside building; the other well placed next to building.

Results to date:
No Futher Action (NFA) for both soils and groundwater. Site Rehabilitation Completion Order(SRCO)issued on 4/27/04.

Cost to Design and Implement:
$72,458

Costs

Cost for Assessment:
  $92,120.30
Cost for Operation and Maintenance:
  $29,264 = O&M $8,689 = Monitoring
Total Costs for Cleanup:
  $202,531

Lessons Learned

1. Good soil sampling under the building providing good design of SVE system.
