by:InSitu Remediation Services Limited (IRSL) based inBurlington, ONTARIO (CANADA)
Harnessing powerful reducing compounds to chemically mitigate impacts in place. The other half of a redox reaction, chemical reduction results in the gain of electrons. One of the reactants in the reaction is oxidized, losing electrons; the other reactant is reduced, gaining electrons. In In-Situ Chemical Reduction (ISCR), reducing ...

by:Verhoeve Milieu & Water based inDordrecht, NETHERLANDS
A recently proven technique is in situ chemical reduction (ISCR). Verhoeve Environment & Water frequently applies this in soils contaminated with chlorinated solvents (VOCL). It is based on the chemical reaction of zerovalent iron with chlorinated compounds, according to: 2Fe + R-Cl + 3H2O = 2Fe + R_H+ 3OH-+ H2 + Cl-. ...
Manufactured by:Cascade Drilling based inBothell, WASHINGTON (USA)
Remediation of contaminated soil and groundwater through the use of chemical reagents is effective for a variety of contaminants and geologic site conditions. Cascade has both the expertise and technology for a wide range of options including: In Situ Chemical Oxidation (ISCO), In Situ Chemical Reduction (ISCR) and ...

by:Sol Environment - Solétanche Bachy Group based inNanterre, FRANCE
The redevelopment of former industrial sites is a major challenge facing site owners and spatial planning decision makers. Sol environment has major assets in the field thanks to its “on-site”-oriented specialty areas and its ability to formulate all-inclusive ...
Manufactured by:In-Situ Oxidative Technologies, Inc (ISOTEC) - Soil & Groundwater Remediation based inLawrenceville, NEW JERSEY (USA)
ISOTEC maintains a 'state-of-the-art' research and development (R&D) laboratory with the capability to perform custom treatability studies. Our laboratory is a EPA-registered facility and maintains the necessary regulatory agency notifications needed in compliance with RCRA for treatability testing laboratories. Our laboratory is staffed with a full time research scientist with over 15 years ...
by:Trium Environmental Inc. based inCalgary, ALBERTA (CANADA)
Chemical reduction is an effective remediation technique to address organic pollutants. Reductants works by accepting an electron and safely degrade/destroy the contaminant. Our expertise with reductants including zero valent iron (ZVI) allows us to ensure the right reductant is applied for the ...
by:Dajak based inWilmington, DELAWARE (USA)
Chemical oxidants and reductants react quickly and effectively with many organic contaminants, including petroleum hydrocarbons and chlorinated solvents. The challenge is getting the reagents to contact the contaminant, often over an extended time frame. Practitioners refer to chemical oxidation and reduction in the subsurface as a 'contact sport.' Applied correctly, the process can reduce ...
by:InSitu Remediation Services Limited (IRSL) based inBurlington, ONTARIO (CANADA)
Reducing time and cost with innovative integrated approaches. Most remediation projects require the use of a suite of approaches in order to meet the remedial objectives for the site. Most technologies have limitations and struggle with the removal of the last 5–10% of the contaminant mass within the aquifer. Yet, most projects require the removal of > 99% of the contaminant mass in ...
