Colloidal Carbon Barrier Protects Neighborhood from Chlorinated Solvent Plume








This case study reviews a field-scale pilot test using REGENESIS technologies for in situ groundwater treatment of chlorinated volatile organic compounds (CVOCs) at high concentrations, in a fast-moving, aerobic aquifer beneath a residential neighborhood. The CVOCs were treated using a unique combination of remediation technologies, symbiotically promoting sorption-enhanced reductive dechlorination (ERD) via biotic and abiotic processes. Hamp, Mathews & Associates, Inc., a leading environmental consultant, enlisted REGENESIS to design and install an in situ permeable reactive barrier (PRB) to fully treat the tetrachloroethene (PCE), trichloroethene (TCE), cis-1,2-DCE (cis-DCE), and vinyl chloride, converting them into nontoxic end products such as ethene, ethane, carbon dioxide, and chloride.


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.

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.

PFAS Remains at Non-Detect After 20 Months Following Application of PlumeStop at DoD Site










This updated case study reviews a pilot test to remove PFAS risk via an in situ colloidal activated carbon barrier at Camp Grayling in Crawford County, Michigan, a large year-round military training center operated by the Michigan Army National Guard (MIARNG). Colloidal activated carbon was selected because of the expected rapid reductions of PFAS by removal from the dissolved mobile phase, as well as its expected lower total project costs when compared to operating a mechanical system over a similar time. Download the case study to learn how the colloidal activated carbon permeable reactive barrier treated PFAS to non-detect.
