Remediation of TCE Plume Speeds Sale of Brownfield Site

This case study reviews a former manufacturing site in Fullerton, CA, where a trichloroethylene (TCE) plume contaminated the groundwater and prevented the sale of the brownfield site. In order to complete the remediation and move forward with the sale, Hargis + Associates worked with REGENESIS to develop an in situ chemical reduction (ISCR) design to address the plume. REGENESIS designed an injection plan using micron-scale Zero Valent Iron (ZVI) due to its proven ability to effectively reduce contaminant levels within a subsurface environment. In just one month following the application, monitoring shows successful reduction of the TCE plume.

ZVI Optimized for Reactivity and Superior Distribution

REGENESIS offers S-MicroZVI®, an advanced zero-valent iron (ZVI) product proven to accomplish In Situ Chemical Reduction (ISCR) of contaminants within the subsurface environment. S-MicroZVI is delivered as a colloidal suspension 40% ZVI by weight in glycerol with a particle size of less than 5 microns. S-MicroZVI is manufactured using a state-of-the-art sulfidation process resulting in a particle coating which increases activation toward specific contaminants and extends performance longevity. S-MicroZVI destroys contaminants abiotically and applied to stimulate ISCR-enhanced bioremediation.

Global Retailer Enters Into Elective Site Cleanup Agreement and Achieves No Further Action

This case study reviews the site of a global retailer based in Arkansas, where historic offsite dry cleaning operations caused tetrachloroethylene (PCE) contamination in the groundwater. A previous bioremediation attempt successfully remediated a majority of the site, but one persistent well remained. Environmental Services Group, Inc. (ESGI) partnered with REGENESIS to design a bioremediation plan that would apply PlumeStop Liquid activated Carbon, HRC and BDI Plus to eliminate the remaining contaminants of concern (COCs). After applications of these technologies from REGENESIS, all COCs were below the acceptable threshold levels, and as a result the site achieved No Further Action (NFA) in January of 2020.

Turn Polluted Aquifers into Purifying Filters with PlumeStop

PlumeStop Liquid Activated Carbon is a break-through groundwater remediation technology that reduces dissolved phase contaminant plumes in days. Composed of extremely fine particles of activated carbon (1‐2μm) suspended in water through a proprietary dispersion chemistry, PlumeStop flows into the subsurface at low pressure and achieves consistent, reliable distribution – a capability unlike any other form of activated carbon used for groundwater remediation today.

Low-cost Bioremediation of Chlorinated Solvents

HRC® is an engineered, hydrogen release compound designed specifically for enhanced, in situ anaerobic bioremediation of chlorinated compounds in groundwater or highly saturated soils. HRC enables enhanced anaerobic biodegradation by 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 enhanced reductive dechlorination. Due to its capability of being applied via permanent wells, direct-push, and excavations, this reagent allows for clean, low-cost, non-disruptive application.

Accelerated Treatment of Intermediate Compounds

BioDechlor INOCULUM® Plus (BDI Plus) is designed to provide rapid and effective treatment of undesirable anaerobic dechlorination intermediates such as dichloroethene (DCE) and vinyl chloride (VC), and is a low-cost means of enhancing the anaerobic biodegradation process. Once in place, this microbial consortium accelerates the rate of chlorinated contaminant degradation from parent compounds to intermediates like DCE and VC and completely through to harmless end products such as ethene and ethane. It is highly compatible with a range of electron donors.

Excavation With RegenOx Successfully Treats PHC Plume

This case study reviews a former gas station site in Buffalo, New York that required remediation due to leaking underground storage tanks. Together with REGENESIS, C&S Consulting designed an in situ remediation strategy to target the residual contaminant plume. RegenOx® in situ chemical oxidant was chosen because of its ability to target petroleum hydrocarbons and its non-corrosive properties. As part of the New York State Department of Environmental Conservation (NYSDEC) Brownfield Cleanup Program, C&S designed a complex remediation program to ensure a quick and affordable solution. Successful remediation enabled the construction of a 350,000 sq. ft. $110 million facility at the Buffalo Niagara Medical Campus.

ISCO Solution Gets Sites to Closure Quickly

RegenOx in situ chemical oxidation (ISCO) directly oxidizes contaminants while its catalytic component generates highly oxidizing free radicals that rapidly destroy target contaminants, including petroleum hydrocarbons and chlorinated compounds. RegenOx is an injectable, two-part ISCO reagent that combines a solid sodium percarbonate based alkaline oxidant (Part A), with a liquid mixture of sodium silicates, silica gel and ferrous sulfate (Part B), resulting in a powerful contaminant destroying technology. The chemical oxidation reactions can continue to propagate in the presence of RegenOx for periods of up to 30 days on a single injection.

Case Study - Combined Amendment Approach Treats Chlorinated Solvents

Combined Amendment Approach Using ZVI Successfully Treats Chlorinated Solvents

This case study reviews a formerly undeveloped site in downtown Jacksonville that was impacted with chlorinated solvents in the groundwater and metal-impacted soils. The site required remediation prior to moving forward with development. Ryan Companies US, Inc. was under contract to purchase the property from the site owner and was seeking an expedited closure of the site prior to completion of construction. To treat the chlorinated solvent groundwater plume, Terracon selected multiple technologies from REGENESIS, including PlumeStop, zero-valent iron (ZVI), Bio-Dechlor Inoculum Plus (BDI Plus), and Hydrogen Release Compound (HRC).

Innovative Approach Reduces Benzene to Achieve Closure

This case study reviews a gas station site in Greenville, Alabama where petroleum hydrocarbon contamination was present in the subsurface for decades. This site is part of an environmental liability transfer and Antea Group assumed the liability for this site. Antea Group required an effective remedial solution that would result in rapid site closure. Antea Group partnered with REGENESIS to create a remedial design using an in situ chemical oxidation (ISCO) treatment paired with an aerobic bioremediation technology to ensure a complete treatment of this site. PersulfOx, PlumeStop, and ORC Advanced were applied to quickly reduce benzene levels to non-detect, resulting in successful regulatory closure.
