Anticipated Shut-off of Pump and Treat System for PFAS at Superfund SiteDue to past operations at a former solvent recovery facility, the soil and groundwater were contaminated with PFAS. PlumeStop, a cost-effective colloidal activated carbon technology, was applied in situ to rapidly adsorb the PFAS contaminants in the upgradient water onto the micron-scale activated carbon.

After the initial application of PlumeStop, the PFAS concentrations have quickly decreased within the application area. Additionally, sampling shows that the water is not exceeding any of the EPA-determined triggers that are being tested downgradient. The anticipated cost savings that this mode of operation will provide the client is approximately $400,000 per year.

Turn Polluted Aquifers into Purifying Filters with PlumeStop

PlumeStop® Liquid Activated Carbon™Contaminant retardation is now a controllable variable 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 wide-spread distribution – a capability unlike any other form of activated carbon used for groundwater remediation today.

Colloidal ZVI with Excellent Reactivity and Longevity

Colloidal ZVI with Excellent Reactivity and LongevityAquaZVI is proven to promote In Situ Chemical Reduction (ISCR) of contaminants within the subsurface environment. It is delivered as a colloidal suspension at 40% ZVI by weight with particle size in the range of less than 5 micron. AquaZVI is an aqueous suspension manufactured employing a state-of-the-science sulfidation process resulting in a particle coating which increases activation toward specific contaminants and extends performance longevity. While this remediation product destroys contaminants abiotically, it can also be employed to stimulate ISCR-enhanced bioremediation.

Case Study: WSP Significant Reduces VOCs at Rail Site

Case Study: WSP Significant Reduces VOCs at Rail SiteGroundwater contamination was caused by discrete releases of chlorinated solvents at a Rail Site in Quebec. A combined remedy approach using PlumeStop and AquaZVI was chosen because it allows for the highest treatment efficiency at the lowest possible cost. A pilot test was conducted in early November. WSP constructed in situ microcosms (ISMs) using aquifer material which were deployed before the amendment injection, with the amendment successfully applied under low pressure, despite wintery conditions. After conducting the pilot test, data for samples collected within the treatment barrier indicated significant contaminant concentration decreases.
