Technology Description and Technical Support Services


Bioaugmentation has emerged as one of the most effective techniques for performing in-situ treatment of chlorinated solvent-contaminated saturated soils and groundwater in a safe and economical manner.  The technology involves injecting halorespiring bacteria, nutrients, and other media into the subsurface to establish a bioactive treatment zone.  The halorespiring bacteria stoichiometrically convert chlorinated solvents to non-toxic byproducts (ethenes) within the treatment area.

  • Cleanup of chlorinated solvents to below cleanup criteria (low ppb concentrations)
  • Effective DNAPL treatment
  • Non-toxic end-product (ethene) instead of vinyl chloride
  • Expedited site closure (months rather than years)
  • Decreased treatment costs because multiple rounds of treatment are not required
  • No contaminant rebound as adsorbed-phase constituents are treated.
  • Mobile, in-situ treatment approach limits on-site disruptions
  • Technology can be used for source area treatment or as a polishing treatment step
  • Safe, low risk treatment
    • Does not promote contaminant migration
    • Application by low pressure methods
    • Low risk to on-site workers
    • No exothermic chemical reactions
    • No vapor control required
    • No hazardous material used
  • Low capital and O&M costs compared with conventional environmental remediation technologies
  • Ready integration with other source zone treatments, including recirculating wells and surfactant treatment
