Applicability
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
