Turn Polluted Aquifers into Purifying Filters with PlumeStop

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

AquaZVI 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.

Client Spotlight: Mike Gefell, Principal Scientist at Anchor QEA

For Mike Gefell, Principal Scientist at Anchor QEA, understanding the complexities of groundwater and protecting this resource deserves great attention, and it is an aspect of our environment he has devoted his entire career to. His specialized field, known as quantitative hydrogeology, involves the analysis of hydrologic processes, including precipitation, groundwater flow, water-well yield, discharge to surface water, and water quality. With 29 years of industry experience in hydrogeology, Gefell has become a highly respected specialist. “I really enjoy quantitative hydrogeology,” says Gefell. “All my work focuses on protecting ecological and human receptors and water resources, and understanding the relationships between water and environmental risk.”

Scott Wilson Answers Your PFAS Questions

This article published in Wiley’s Remediation Journal reviews a site impacted with petroleum hydrocarbons, perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), and other perfluoroalkyl sulfonates (PFAS). A single application of PlumeStop resulted in a significant reduction of contaminant concentrations to below standards for 18+ months since the injection. Modeling indicates that the PlumeStop application event should keep the PFAS contained within the source area for upwards of 100 years. Details of the remedial design approach are provided along with results of its implementation.

Long-Term, Low-Cost Remediation of Chlorinated Solvents

3-D Microemulsion® is an injectable electron donor optimized for low cost, long-lasting in situ remediation of chlorinated solvents. Its engineered, wide-area subsurface distribution significantly reduces the number of injection points and events required, resulting in time and cost savings. A viable, long-term source of staged-release hydrogen on the order of 2-4 years from a single application, this technology is faster and often lower cost than lengthy natural attenuation approaches.

Accelerated Treatment of Intermediate Compounds

Bio-Dechlor 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.

When to Use Continuous Monitoring to Resolve Vapor Intrusion Challenges

Several common questions arise when investigating a site for potential vapor intrusion related challenges. Often it is difficult to discern whether vapor intrusion is occurring and if so, where it is entering the building. Once vapor intrusion is discovered and mitigation ensues, an added concern is whether or not the mitigation achieved key risk reduction objectives or actually increased potential exposures. This guest blog post will explain when to use continuous monitoring to measure contaminant vapors in indoor air.
