Technology-Based Solutions for the Environment



REGENESIS offers a range of specialty soil and groundwater remediation products, each one has been specifically designed for environmental applications with an emphasis on performance, cost-effectiveness, ease of use and environmental safety.

Generally speaking the use of any one of REGENESIS products offers the following benefits:

  • Food grade, environmentally safe and easy to handle materials.
  • Patented controlled-release technology (CRT)™ provides maximum product longevity and optimized oxygen and hydrogen release profiles.
  • Lower costs and a significantly smaller carbon footprint than operations and maintenance intensive engineered mechanical systems.
  • In situ or in-place treatment eliminates any requirements for permanent on-site equipment, piping, tanks, etc.
  • Enhanced biodegradation rates typically 10 to 100 times faster than intrinsically slow, naturally occurring rates.
  • Greater efficiency and cost-effectiveness than high volume, rapidly consumed or wasted commodity products.
  • Often lower cost than long-term, monitored natural attenuation (MNA) or “do nothing” type approaches.
  • Experience and a proven track record of success with hundreds of published papers and product applications on over 16,000 sites worldwide.
  • Professional and highly experienced technical services, application design and cost estimation free of charge.

Enhanced Aerobic Biodegradation

Oxygen Release Compound (ORC®) and Advanced Oxygen Release Compound (ORC Advanced®)are specifically designed and used for the enhanced or accelerated, in situ aerobic biodegradation of a wide-range of petroleum hydrocarbons or any aerobically degradable substance. Enhanced aerobic biodegradation is the well understood and widely studied practice of adding oxygen (an electron acceptor) to groundwater and/or soil to increase the number and vitality of indigenous microorganisms able to perform biodegradation. REGENESIS’ ORC and ORC Advanced products are typically injected into groundwater or applied into open excavations where upon hydration they provide a controlled-release source of oxygen for periods of up to 12 months on a single application.

Enhanced Anaerobic Biodegradation (Reductive Dechlorination)

3-D Microemulsion, Hydrogen Release Compound (HRC®), Extended Formula Hydrogen Release Compound (HRC-X®), Hydrogen Release Compound PRIMER (HRC PRIMER®) are specifically designed and used for the enhanced anaerobic biodegradation of a wide-range of contaminants including chlorinated contaminants, pesticides, nitroaromatics (explosives and dyes), inorganics (nitrates and perchlorates), etc. Enhanced anaerobic biodegradation is the practice of adding hydrogen (an electron donor) to groundwater and/or soil to increase the number and vitality of indigenous microorganisms able to perform the naturally occurring process of reductive dechlorination. During this process, certain naturally occurring microorganisms replace chlorine atoms on chlorinated contaminants with the newly available hydrogen effectively reducing the contaminant to a less harmful substance with the preferred and innocuous endpoints of ethane or ethane.

In Situ Chemical Oxidation (ISCO)

PersulfOx® Catalyzed Persulfate is an in situ chemical oxidation reagent that destroys organic contaminants found in groundwater and soil through powerful yet controlled chemical reactions. PersulfOx is a sodium persulfate – based technology which employs a patented catalyst to enhance the oxidative destruction of both hydrocarbons and chlorinated contaminants in the subsurface. The PersulfOx catalyst is a silica-based, microscopic surface on which oxidants and contaminants can come together and react in a specific process known as “surface mediated oxidation” where oxidation reactions occur repeatedly on the surface of the catalyst. Typically, sodium persulfate is activated with the addition of heat, chelated metals, hydrogen peroxide, or base in order to generate sulfate radicals. These activation processes are inherently complex, costly and can pose additional health and safety risks. In comparison, PersulfOx provides an all-in-one product with built-in-activation making it a relatively safe and easy-to-use ISCO reagent. The material itself is easily mixed with water and applied into the contaminated matrix using subsurface injection techniques or soil mixing tools.

RegenOx® is a product designed specifically for the rapid, in situ and/or ex situ chemical oxidation of a broad range of contaminants including both chlorinated solvents and petroleum hydrocarbons. RegenOx has been rigorously tested in both the laboratory and the field on petroleum hydrocarbons (TPH, BTEX, MTBE, etc), polyaromatic hydrocarbons (naphthalene, phenanthrene, etc) and chlorinated hydrocarbons (PCE, TCE, TCA, etc). In situ chemical oxidation (ISCO) is a process that involves the injection of reactive chemical oxidants into groundwater and/or soil for the primary purpose of rapid contaminant destruction (often within days to weeks). Also known as ISCO, this process is most often deployed at sites with relatively high contaminant concentrations in a source area and in downgradient plume(s). Chemical oxidation of high concentration areas is often part of a multi-step remediation regimen that paves the way for more biologically mediated, less costly approaches such as enhanced biodegradation or monitored natural attenuation. RegenOx delivers rapid and effective contaminant mass reduction using a solid alkaline oxidant that is activated to a very high performance level through the action of a unique catalytic complex. Once in the subsurface, the combined product produces an effective oxidation reaction comparable to that of Fenton’s Reagent without a violent exothermic reaction. Strategies employing multiple RegenOx injections coupled with follow-on enhanced biodegradation can be used to cost-effectively treat highly contaminated sites to regulatory closure.

Metals Immobilization

Metals Remediation Compound (MRC®) is a product designed to remove a dissolved metals, particularly hexavalent chromium (Cr6) from groundwater via in situ immobilization while providing an additional electron donor substrate for the enhanced biodegradation of chlorinated compounds. MRC is simply injected into groundwater where upon hydration it becomes subject to microbial biodegradation. While being degraded it slowly releases its active ingredient, a benign organosulfur compound (BOC). Upon contact with metal ions, the BOC reacts to produce a metal-organosulfur complex. This complex sorbs strongly to soil and is immobile in the subsurface. Over time the organic portion of the metal-organosulfur complex is also biodegraded and the complexed metal is incorporated into the soil matrix as a sulfide solid. The BOC can also act as a direct reductant for metals like chromium and uranium that precipitate as hydroxides and oxides. MRC also provides a substrate similar to that of HRC for accelerated reductive dechlorination of chlorinated compounds making it highly suitable for mixed plumes containing both metals and chlorinated


Bioaugmentation is the term used to describe the addition of cultured microorganism to the subsurface that are capable of biodegrading or transforming specific groundwater/soil contaminants. In some cases certain microorganisms are more specialized at degrading specific target contaminants, i.e some microbes can degrade DCE and VC but not TCE or vice-versa. As a result, remediation industry practices and recommendations are now shifting toward a more prescriptive approach to bioaugmentation to achieve cost-savings and speed up site remediation.

Bio-Dechlor INOCULUM® PLUS is an enriched natural microbial consortium containing species of Dehalococcoides sp. (DHC). This microbial consortium has since been enriched to increase its ability to rapidly dechlorinate contaminants during in situ bioremediation processes. Bio-Dechlor INOCULUM has been shown to stimulate the rapid and complete dechlorination of compounds such as tetrachloroethene (PCE), trichloroethene (TCE), dichloroethene (DCE), and vinyl chloride (VC). The most current culture of Bio Dechlor INOCULUM PLUS(+) now contains microbes capable of dehalogenating halomethanes (e.g. carbon tetrachloride and chloroform) and haloethanes (e.g. 1,1,1 TCA and 1,1, DCA) as well as mixtures of these halogenated contaminants.
