Parisian Cleaners, Orlando, Florida

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

Contaminant Media Concentration (ppb) Nondetect
Tetrachloroethene (PCE) groundwater 320 ppb
Tetrachloroethene (PCE) soil 130 ppb
1,2,4-trimethylbenzene groundwater 365 ppb
1,2,4-trimethylbenzene soil 410 ppb
1,3,5-trimethylbenzene groundwater 120 ppb
naphthalene soil 570 ppb
Trichloroethene (TCE) groundwater 4.4 ppb
xylenes soil 188 ppb

Pathways and DNAPL Presence

DNAPL Present

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)


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:


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

Lessons Learned

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