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.
A Liquid Iron Based-Reagent for the Enhanced In Situ Chemical Reduction (ISCR) of Chlorinated Contaminants
 CRS® (Chemical Reducing Solution) is an iron-based amendment for in situ chemical reduction (ISCR) of halogenated hydrocarbon contaminants such as chlorinated ethenes and ethanes. This highly efficient in situ remediation technology contains a form of liquid iron which provides better distribution than can be achieved by directly injecting a solid iron material into the subsurface. The product allows for seamless integration with anaerobic bioremediation, and is easy to apply with the electron donor 3-D Microemulsion.
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: Matt Hall, Senior Engineer and Senior Project Manager at Terracon
 For Matt Hall, Senior Engineer and Senior Project Manager at Terracon Consultants, Inc., a leading environmental consulting and engineering firm and valued REGENESIS client, choosing a career in environmental remediation started with an interest in cleaning up our environment., Once he became immersed in his studies however, he quickly became passionate about the “how-to” aspects that drive the science behind remediation. Shares Hall, “My initial interest soon morphed into a fascination with understanding the science behind the products and the engineering design for remediation implementation.” Eventually, Hall’s commitment to the earth’s environment lead to earning a dual bachelor’s degree from Tulane University in Ecology, Evolution, & Organismal Biology (EEOB), and Environmental Studies. After graduation, he worked as a staff level professional at an environmental engineering firm and worked his way up the ranks before joining Terracon, seven years ago, where he enjoys a diverse range of responsibilities.

Dr. Kram earned his Ph.D. in Environmental Science and Management from the University of California at Santa Barbara, an M.S. degree in Geology from San Diego State University, and his B.S. degree in Chemistry from the University of California at Santa Barbara. He has over 30 years of experience using innovative environmental assessment techniques, has authored articles, national standards and book chapters on the subject, and has taught graduate level courses on related topics. Dr. Kram is the recipient of the NGWA’s prestigious Technology Award, and received the 2014 ASTM Committee D18 Technical Editors Award.
When to Use Continuous Monitoring to Resolve Vapor Intrusion Challenges
Several common questions arise when investigating a site for potential vapor intrusion related challenges. Often it is difficult to discern whether vapor intrusion is occurring and if so, where it is entering the building. Once vapor intrusion is discovered and mitigation ensues, an added concern is whether or not the mitigation achieved key risk reduction objectives or actually increased potential exposures. This guest blog post will explain when to use continuous monitoring to measure contaminant vapors in indoor air.
