PFAS Specific Treatment

Target the 4 key areas of the PFAS Source-Plume system:


Enhancing Ex Situ Techniques


Integrated Treatment / Combining Remedies

  • The above techniques can be combined or paired with other remedial approaches.


Our in situ remediation technologies are suitable for treating a wide range of contaminants in soil and groundwater, across widely varying site types and conditions, including:

  • Petroleum hydrocarbons including BTEX, PAH etc, Chlorinated Solvents, TNT, MNT, DNT, Pesticides, Herbicides, Metals (including CrVI), PFAS and other emerging contaminants. 
  • From high concentrations to very low contaminant concentrations
  • Brownfield land, legacy sites, sites earmarked for redevelopment, or other forms of contaminated land
  • Commercially active facilities including defense, manufacturing, retail, rail, industrial, pharmaceutical, petrochemical, warehousing/logistics sites
  • Treatment types: source treatment, plume treatment, remediation to reduce liability or manage risk of contaminant migration
