Eliminate Risk and Uncertainty 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.

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, completely through to harmless end products such as ethene and ethane. It is highly compatible with a range of electron donors.

Multi-layered Vapor Barrier for New Building Construction

Vapor Intrusion Barriers need to balance two key characteristics, chemical resistance (how well the barrier protects against the chemical of concern) and constructability (the ability to effectively seal all entry pathways in a building). Geo-Seal is a composite system that creates the ideal blend between constructability and chemical resistance by using both high density polyethylene (HDPE) and spray applied asphalt latex. Ideal for new construction, Geo-Seal has been accepted by state environmental agencies across the country, the US NAVY, US AIR FORCE, Fortune 500 Companies, and leading environmental consulting firms around the world.

Upcoming Webinar

Join us for a special vapor intrusion webinar presentation with Dr. Kenneth Tramm, Principal with Modern Geosciences. This presentation will provide us with an overview on investigating vapor intrusion and understanding risk. Joining Dr. Tramm will be Thomas Szocinski, Director of Vapor Intrusion at Land Science, who will share successful vapor mitigation case studies. This live webinar starts Wednesday, May 31st, 2017 at 11am pacific/2pm eastern.

Client Spotlight: Richard Bewley, PhD, Remediation Practice Leader at AECOM

It is not often you meet someone as accomplished as Dr. Richard Bewley.

New In Situ Remediation Mapping Technique Studied by Leading Academics in Sweden Shows Promise

Four leading remediation professionals from Sweden’s academic community have published findings about a new subsurface mapping technique. Their paper investigates the ability to map in situ treatment of chlorinated solvents within the subsurface, using direct current resistivity and time-domain induced polarization tomography (DCIP). The study was completed on a contaminated site in Sweden, where a 3-D Microemulsion® pilot trial had been completed. The results show the extent of the treatment achieved and suggest that this is a promising method for verification of treatment zones.

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.

Destroy a Wide-Range of Contaminants through ISCO

PersulfOx is an advanced in situ chemical oxidation (ISCO) reagent that promotes rapid and sustained destruction of a wide-range of organic contaminants. It is an all-in-one product with a
built-in catalyst, which activates the sodium persulfate component and generates contaminant-destroying free radicals without the costly and potentially hazardous addition of a separate activator. The patented catalyst enhances the oxidative destruction of both petroleum hydrocarbons and chlorinated contaminants in the subsurface.
