Remediation Approaches Overview

for the treatment of contaminated land and groundwater

In Situ Remediation Techniques and Approaches 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

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
