Hydrogeology:

Depth to Groundwater throughout the area varies from about 18 feet to greater than 200 feet below ground surface.

The Site is located in an area of highly weathered and structurally deformed rocks of the Cambrian-Precambrian era. In addition, a portion of the Site rests upon the trace of a thrust plane known as the Musconetcong Fault.

Targeted Environmental Media:
  • - Fractured Bedrock

Contaminants:

The lateral and vertical extent of the plume was not given by the RODs or five-year reviews.

Major Contaminants and Maximum Concentrations:
  • - Tetrachloroethene (not given)
  • - Trichloroethene (100 µg/L)
  • - 1,2-Dichloroethene (not given)
  • - Vinyl chloride (not given)
  • - Carbon tetrachloride (not given)
  • - Chloroform (not given)
  • - 1,1,1-Trichloroethane (not given)
  • - 1,1-Dichloroethane (not given)
  • - 1,2-Dichloroethane (not given)
  • - 1,2-Dichloropropane (not given)

Site Characterization Technologies:

No technologies selected.


Remedial Technologies:

  • - Pump and Treat
Comments:
The pump and treat system began operation in 1999. Three groundwater monitoring system wells were selected as extraction wells. The system included: a Perforated tray air stripper, continuous backwash sand filters, an inclined plate gravity settler, and flow meters at critical areas of the Groundwater treatment system

The system pumps 65 gpm.
Remediation Goals:

MCLs were selected as the cleanup goals.


Status:

The system continues to operate and concentrations in monitoring wells are approaching cleanup goals.
