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.
Client Spotlight: Jeffrey Holden, Senior Engineer at GEI Consultants, Inc.
 For Jeffrey Holden, Senior Engineer at GEI Consultants, Inc., a leading environmental services firm and valued REGENESIS client, helping to preserve our planet’s environment began upon graduation from Clarkson University, where he earned bachelor’s degrees in both Mechanical and Aeronautical as well as Civil and Environmental Engineering. He worked for nearly 25 years at a leading global design, engineering and management consulting company, ultimately managing roles as a Senior Engineer, Vice President, and Principal in Charge. He shifted gears to join GEI in December of 2016 and immediately found himself immersed in new and refreshing multi-disciplinary roles. Read more in our client spotlight.
Webinar on Analytical Challenges and Solutions
In this webinar we are pleased to have a special presentation by Heather Lord PhD, Environmental Research & Development Manager for Maxxam. In this presentation she will discuss analytical challenges and solutions when using PlumeStop Liquid Activated Carbon for in situ remediation of chlorinated solvents in groundwater. Joining Heather Lord will be Rick McGregor, President of InSitu Remediation Services Ltd, who will share case studies of sites using the analytical strategies discussed in Dr. Lord’s presentation. This live webinar starts Thursday, November 15th, 2018 at 11am pacific/2pm eastern.
Webinar Recording Now Available
In this webinar we were pleased to have a special presentation by vapor intrusion experts, Dr. Blayne Hartman of Hartman Environmental and Dr. Mark Kram of Groundswell Technologies. In this presentation they discussed updates regarding vapor intrusion pathway issues, as well as the use of continuous monitoring data. The full recording is now available here.

A former dry-cleaner in Sacramento released chlorinated solvents and petroleum compounds in groundwater. Electrical Resistance Heating (ERH) was selected to remove contaminant mass in the source area. During ERH, 3-D Microemulsion® was used for Enhanced Reductive Dechlorination in order to treat the distal plume. Fugro USA Land, Inc. and REGENESIS collaborated on the site design and remedial application, resulting in a reduction in the PCE plume to nearly one-third its original size and reduced the highest PCE concentrations by 2 orders of magnitude.
