EZVI and EZVI-CH4 ISCR Technologies for CVOC Source Treatment

Antimethanogenic EZVI-CH4™ uniquely combines the proven chemistry of the National Aeronautics and Space Administration’s (NASA) EZVI Technology with the selective power of Provectus’ Provect-CH4® methanogen inhibitors to yield a genuinely new, antimethanogenic DNAPL technology that is capable of direct in situ destruction of source materials. It provides:

  • Provect-CH4™ methanogenic inhibitor (blended within fermentable H donor component of EZVI)
  • Matching physical chemistry (hydrophobic) enables complete miscibility (contact) with DNAPLs
  • Sequestration (phase partitioning) of hydrophobic contaminants (e.g., halogenated hydrocarbons) into outer liquid oil membrane
  • Mass flux reduction from source areas due to dramatic decrease in water solubility of contaminants
  • Food grade soybean oil as a slow-release, long term H donor
  • Powdered, highly reactive, ZVI (< 5 µm size distribution) encapsulated within water/VO micelles (not in direct contact with groundwater) will only react with contaminants that are hydrophobic
  • Abiotic reactions primarily occur in the aqueous interior of emulsion where ZVI is suspended in water
  • Biotic reactions primarily occur on the exterior of the emulsion and downgradient (hydrologically) of the EZVI implementation zone

EZVI-CH4 is the only technology engineered to directly destroy DNAPL while significantly decreasing the wasteful consumption of hydrogen donor by actively controlling the production of methane.

    Site: Former Manufacturing Facility – East Orange, NJ Constituents of Interest: Trichloroethylene, cis-1,2-Dichloroethene and Vinyl Chloride Lead Contractor: Innovative Environmental Technologies, Inc. (IET) Project Summary Soil and groundwater at a former manufacturing facility in East Orange, NJ were impacted by trichloroethylene (TCE), cis-1,2, dichloroethene (cis-1,2-DCE) and vinyl chloride (VC) due to historical releases. The geology […]
