    Remediation Approaches Overview

    for the treatment of contaminated land and groundwater

    In Situ Remediation Techniques and Reagents offered by REGENESIS:

     

    Bioremediation – Biological treatment

    • Enhanced aerobic bioremediation  ORC Advanced©

    • Enhanced anaerobic biodegradation – enhanced reductive dechlorination (ERD), enhanced dehalogenation 3DME©  HRC©

    • Sorption and enhanced biodegradation – aerobic/anaerobic oxidation and anaerobic reduction  PlumeStop©  PetroFix®

    • Bioaugmentation (Dehalococcoides Sp.)  BDI Plus©

     

    Chemical Treatment – Chemical Oxidation/Reduction/Immobilisation

    • In Situ Chemical Oxidation (ISCO)  RegenOx©  PersulfOx©

    • In Situ Chemical Reduction (ISCR)

      • Colloidal, Sufidate, Zero Valent Iron (ZVI)  S-MicroZVI©

      • Liquid Ferrous Iron   CRS©

    • Metals Immobilisation  MRC©

    • In Situ Sorption

      • Colloidal Activated Carbon – Sorption only, or combined with enhanced biological degradation

        PlumeStop©  PetroFix®

     

    PFAS Specific Treatment

     

    Enhancing Ex Situ Techniques

     

    Integrated Treatment / Combining Remedies

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

    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
