SAN CLEMENTE, CA – (February 13, 2019) REGENESIS, the recognized global leader in in situ soil and groundwater remediation technologies, is proud to announce the launch of S-MicroZVITM.  The new in situ chemical reduction (ISCR) amendment is an innovative, micron-scale, sulfidated zero-valent iron (ZVI) remedial amendment enabling environmental practitioners with a complete solution to quickly and effectively eliminate chlorinated hydrocarbon contaminants on a wide variety of sites. S-MicroZVI promotes the destruction of many organic pollutants and is most commonly used with chlorinated hydrocarbons.  Engineered to provide an optimal source of micro-scale ZVI, S-MicroZVI is easy to use and delivers enhanced reactivity with the target contaminants via multiple reaction pathways. S-Micro ZVI destroys chlorinated contaminants through a direct chemical reaction and also stimulates anaerobic biological degradation by rapidly creating a reducing environment favorable for reductive dechlorination. The launch of S-MicroZVI replaces REGENESIS’ AquaZVI and MicroZVI technologies and introduces a highly effective sulfidated ZVI remedial fluid proven in the field to accelerate contaminant reduction by more than an order of magnitude when compared to commodity iron products.

REGENESIS’ PhD-level scientists developed S-MicroZVI as a glycerol suspension combining micron-scale iron with an iron sulfide surface catalyst, specifically designed to rapidly remove contamination from groundwater and soil.  This proprietary technology results in rapid reduction of contaminants while promoting intrinsic biodegradation. Unlike other remedial technologies, S-MicroZVI can be easily applied, injected under low pressure into the subsurface. The product does not require high pressure “fracking” for application and is applied with ease using readily available equipment.

REGENESIS has spent considerable time testing S-MIcroZVI in laboratory and field studies and it has minimal impacts on groundwater quality, and geochemistry.  Developed by Dr. John Freim, a technical innovator in the development of in situ chemical reduction (ISCR) technologies, S-MicroZVI promises to be the most easily distributed, reactive and cost-effective ZVI product available on the market today. Scott Wilson, President and CEO of REGENESIS, shares “Dr. Freim and the R&D Team have accomplished something quite extraordinary in the development of S-MicroZVI and we are excited about the results we have seen to-date in the lab and testing in the field. The new and improved ZVI amendment addresses the market’s need for a safe, effective and easy to apply ZVI amendment that is proven to be superior at reducing chlorinated hydrocarbon contaminant levels when compared to other approaches.”

REGENESIS, a world-class leader in soil and groundwater remediation technologies, provides safe and effective solutions addressing a wide range of contaminants, including emerging contaminants like PFOS/PFOA.

Remediation Technical Bulletin: PersulfOx Treatment Reduces PCP Contamination by >99%

pcp-tech-bulletinREGENESIS recently released a new technical bulletin focused on PersulfOx’s ability to remediate pentachlorophenol (PCP) – a pesticide and disinfectant used industrially as a wood preservative. A study, performed by Regenesis, investigated the ability of PersulfOx to treat PCP contamination. Water samples containing PCP (20 mg/L) were treated with PersulfOx and after 27 days, a >99.9% contaminant reduction was observed. To read more about this study, click here.

Announcing A New Remediation Technology: PlumeStop™ Colloidal Biomatrix

REGENESIS recently announced the commercial launch of its latest product offering: PlumeStop™ Colloidal Biomatrix. This new and innovative remediation technology was developed to stop migrating groundwater contaminant plumes by rapidly reducing contaminant concentrations with a sorptive medium while also enhancing or accelerating microbial-driven biodegradation process.

PlumeStop was officially launched during last week’s Battelle-sponsored Ninth International Conference on Remediation of Chlorinated and Recalcitrant Compounds in Monterey, Calif. Regenesis’ President and CEO Scott Wilson welcomed over 100 attendees to an exclusive luncheon held during the event which featured a presentation from Dr. Jeremy Birnstingl, VP of Environmental Technology at Regenesis. Dr. Birnstingl discussed the progression of PersulfOx® Catalyzed Persulfate, an ISCO technology, which the company successfully brought to market in 2012.

PlumeStop is a black, silky liquid that is easy to inject into groundwater where it widely distributes into the subsurface.

Dr. Ben Mork, VP of Research & Development at Regenesis, was the final speaker at the luncheon and unveiled the groundwork for PlumeStop. Dr. Mork explained that its unique effectiveness is derived from the first-ever use of a highly dispersible, fast-acting, sorption-based technology which captures and concentrates dissolved-phase contaminants within its structure or matrix. Once groundwater contaminants are sorbed (held) onto the matrix, natural biodegradation (bio) processes proceed at an accelerated rate, forming a highly effective “biomatrix.” He also pointed out that Plumestop secures groundwater contaminant concentration reduction very rapidly (in days) and is effective on most organic groundwater contaminants including hydrocarbons, halogenated compounds and a wide variety of volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs).

New ISCO Remediation Video: PersulfOx Catalyzed Persulfate Pre-Application Mixing Demonstration

PersulfOx® Catalyzed Persulfate offers remediation professionals a new choice in persulfate-based ISCO reagents. The material itself is supplied as a 100% soluble, granular material that is easily mixed with water and then applied to the contaminated subsurface.

PersulfOx is a single component product with built-in-activation making it distinctly different from traditional activated persulfate. The use of activated persulfate is inherently more complex and hazardous as it requires a separate, external activation step using either hydrogen peroxide, sodium hydroxide, chelated iron or heat. PersulfOx is uniquely engineered to provide efficiency and cost savings as a result of simplified handling and field application. It also reduces the health and safety risks associated with the storage, management and use of hazardous activators.

To see just how easy PersulfOx is to apply watch the short video below featuring Craig Sandefur, VP of Technology at REGENESIS, giving a short pre-application mixing demonstration.

Enhanced Aerobic Bioremediation Application in the Arctic Circle

Enhanced Aerobic Bioremediation

Winter has arrived…take a look at these pictures of a recent enhanced aerobic bioremediation application using Oxygen Release Compound ADVANCED (ORC ADVANCED®) in the Arctic Circle.

This project was completed using direct-push injection in ambient air temperatures generally between 10 and 20 degrees Fahrenheit with heavy snow at times. In spite of the deep freeze and the cold temperatures, the ORC Advanced injection went as planned and the subsurface had no problem accepting the ORC Advanced slurry.
