Global Retailer Enters Into Elective Site Cleanup Agreement and Achieves No Further Action
This case study reviews the site of a global retailer based in Arkansas, where historic offsite dry cleaning operations caused tetrachloroethylene (PCE) contamination in the groundwater. A previous bioremediation attempt successfully remediated a majority of the site, but one persistent well remained. Environmental Services Group, Inc. (ESGI) partnered with REGENESIS to design a bioremediation plan that would apply PlumeStop Liquid activated Carbon, HRC and BDI Plus to eliminate the remaining contaminants of concern (COCs). After applications of these technologies from REGENESIS, all COCs were below the acceptable threshold levels, and as a result the site achieved No Further Action (NFA) in January of 2020.

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. Due to its capability of being applied via permanent wells, direct-push, and excavations, this reagent allows for clean, low-cost, non-disruptive application.
Accelerated Treatment of Intermediate Compounds
BioDechlor 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.
Technology Webinar Recording: Optimizing ZVI
In this webinar we were pleased to have a special presentation from John Freim, PhD, ZVI Product Manager and Director of Materials Science at REGENESIS. Dr. Freim discussed the benefits of using zero-valent iron (ZVI) as a powerful remediation amendment for the in situ remediation of chlorinated solvents. He was joined by James Cobb, CSP, RSO, Director of Health and Safety at REGENESIS, who discussed safety procedures being implemented by REGENESIS in response to COVID-19.The recording of this free webinar is available now.

Working Remotely? Visit Our Remediation Training Library
At REGENESIS, we know that many environmental firms are seeing a reduction in field work as we respond to COVID-19 and most firms have staff working remotely. Many companies are using this time to focus on staff training and getting abreast of new technologies and regulations. So we wanted to bring your attention to our library of pre-recorded webinars that we provide on our website at no charge. Topics include PFAS, as well as remediation of chlorinated solvents and petroleum hydrocarbons in soil and groundwater, and vapor intrusion regulations and mitigation. We’ll also provide certificates of attendance for any webinar viewed upon request by emailing marketing@regenesis.com.
