The area of contamination includes wetlands and surface water. Fractured bedrock is present at the site.
Targeted Environmental Media:
 Fractured Bedrock - Light Non-aqueous Phase Liquids (LNAPLs)
The plume includes an area with a residential property and four neighboring residential properties. Nonaqueous phase liquid (NAPL) is present.
Major Contaminants and Maximum Concentrations:
- Total petroleum hydrocarbons (var)
No technologies selected.
- Chemical Oxidation (In Situ)
Comments:
The initial stages of the remediation included soil excavation and removal. Due to the sensitivity of the impacted wetlands and surface water, no further removal actions, such as the excavation, could be completed.
Perozone was selected as the remedial alternative to treat the remaining petroleum residuals in groundwater and in the capillary fringe soils.
Not documented.
Full-scale remediation is ongoing.
After the removal of impacted soil, the recovery of the bulk of the free phase product and pumping and off-site disposal of groundwater during excavation activities, perozone was selected as the remedial alternative to treat the remaining petroleum residuals in groundwater and in the capillary fringe soils.
