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.


Suitable for treating a wide range of contaminants in soil and groundwater, across many different site types and conditions:

  • Petroleum hydrocarbons including BTEX, PAH etc, Chlorinated Solvents, TNT, MNT, DNT,
  • Pesticides, Herbicides, Metals (including CrVI)
  • PFAS and other emerging contaminants
  • Brownfield land, legacy sites, redevelopment sites, or other forms of contaminated land
  • Remote or restricted access sites
  • Commercially active facilities: defense, manufacturing, retail, rail, industrial, pharmaceutical, chemical, logistics
  • Source Areas and Plumes
  • Remediation to reduce liability or manage risk of contaminant migration
