PFAS Specific Treatment
Target the 4 key areas of the PFAS Source-Plume system:
-
Source Treatment, featuring SourceStop® Solid & Liquid (soils, capillary fringe, groundwater)
-
Plume Treatment with PlumeStop®(groundwater, plume)
-
Warranty offering: PlumeShield™
Enhancing Ex Situ Techniques
-
Enhanced Desorption (increased efficiency of physical extraction/pump and treat systems) RegenOx®
-
Soil mixing or spraying ORC Advanced® , RegenOx® , PetroFix®
Integrated Treatment / Combining Remedies
-
The above techniques can be combined or paired with other remedial approaches.
Applicability
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
