The subsurface geology at the site consists of a fractured bedrock aquifer, with contamination detected in the bedrock fractures present up to 220 ft below grond surface. The majority of contamination was detected in the shallow depths at 40-45 ft. bgs. The ground water velocity is fairly slow.

Targeted Environmental Media:
  • - Dense Non-aqueous Phase Liquids (DNAPLs)
  • - Fractured Bedrock


Major Contaminants and Maximum Concentrations:
  • - Ethanol (355,000 µg/L)
  • - Trichlorofluoromethane (52,000 µg/L)
  • - Trichlorfon (31,000 µg/L)
  • - 1,1,1-Trichloroethane (11,000 µg/L)
  • - Methylene chloride (10,000 µg/L)

Site Characterization Technologies:

No technologies selected.

Remedial Technologies:

  • - Chemical Oxidation (In Situ)
    • Fenton's Reagent
An initial field pilot program consisted of ten days of injecting reagents. Injection was at multiple depths with a majority in the shallow 40 - 45 ft bgs interval.

The results indicated that overall site-wide contamination of total average VOCs was reduced by 93% and average ethanol concentration was reduced by 99%.
Remediation Goals:

None provided


As of April, 2004 the decision on full scale is still pending.
