Hydrogeology:

The site includes fractured shale bedrock that includes a ground water aquifer.

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

Contaminants:

Major Contaminants and Maximum Concentrations:
  • - Trichloroethene (Not provided)
  • - Tetrachloroethene (Not provided)
  • - cis-1,2-Dichloroethene (Not provided)

Site Characterization Technologies:

  • - Borehole Geophysics
    • Other
  • - Flow
  • - Coring

Comments:
Characterization of the site was performed via multiple multilevel sampling systems, including borehole geophysical and hydrological logging and interflow testing, volatile organic compound subsampling from the rock core, rock matrix characterization, and matrix interaction with permanganate (performed in a laboratory).


Remedial Technologies:

  • - Chemical Oxidation (In Situ)
    • Permanganate
Comments:
Injections of sodium permanganate (NaMNO4) began in 2004 and were to take place over 5 years, with 5 additional years of monitoring.
Remediation Goals:

The objective of the project was to reduce the mass flux of contaminants exiting the site.


Status:

Decreased conductivity of the injection wells has impeded the delivery of NaMNO4 and thus in situ oxidation. It is believed that manganese dioxide has precipitated either within or near the injection boreholes or within the hydraulically connected fractures.


Lessons Learned:
