Client Spotlight: Tim McDonald

For Tim McDonald, Vice President with Environmental Services Group, Inc. (ESGI) a career in environmental remediation evolved after years of extensive experience in the oil and gas industry. He shares, “The scientific and engineering mechanisms that can be applied to both protect the environment and prevent damage from industrial activity are very appealing.” In his current role at ESGI, McDonald is responsible for engineering and environmental design work for permit acquisitions that include mining, air, and water discharge. He also manages bioremediation and environmental cleanup that includes soil and water sampling, as well as the remediation of soil and water contamination. Learn more in our client spotlight.

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.

Turn Polluted Aquifers into Purifying Filters 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. 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.

PFAS Webinar Recording: Key PFAS Practice Leaders Share Their Experience

In this webinar we were pleased to have as special guest speakers Jack Sheldon, Senior Remediation Specialist at Antea Group, and Caron Koll, PG, LSP, and PFAS Lead at Antea Group. Their presentation discussed lessons learned from a decade of experience working with PFAS contaminants in groundwater. They were joined by Kristen Thoreson PhD, VP of Research and Development at REGENESIS, who discussed eliminating risk from PFAS via low-cost, in situ remediation with colloidal activated carbon. 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.

Adapting Our Processes in Response to Coronavirus to Provide Continued Support to Our Clients

For many of us, the Coronavirus (COVID-19) has dramatically reshaped all aspects of our personal and professional lives. Its impact on the world of politics and policy has been swift and chaotic with updates and changes occurring daily in an effort to reduce the size and scope of what is now a pandemic. In response to the COVID-19 outbreak, our team has made adjustments to the way we are supporting you, our client partners. Moving forward, we will be conducting client visits and meetings virtually, using our meeting and webinar platforms to help ensure continuity during the coronavirus outbreak, in order to limit exposure to both you and our REGENESIS/Land Science teams. As always, we continue to be dedicated to supporting you and your projects and will remain committed to providing you with timely and effective in-situ soil and groundwater and vapor mitigation solutions. For the most current information on COVID-19, we recommend you rely on the CDC website here.
