Half-Mile Plume Effectively Treated

Combined Remedy Treats TCE Plume at Aerospace SiteAn aerospace manufacturing facility required remediation for a deep and heavily impacted Chlorinated Volatile Organic Compound (cVoc) plume. The extensive depth and size of the plume contributed to the difficulty facing remediation efforts. After conducting pilot tests, Alta Environmental and REGENESIS concluded that Enhanced In Situ Bioremediation (EISB) technology was both cost-effective and feasible for successful remediation of this site. The observation wells continue to be sampled quarterly and are displaying successful reductions in cVOCs.

Long-Term, Low-Cost Remediation of Chlorinated Solvents

3-D MicroEmulsion3-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

Chemical Reducing SolutionCRS® (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 InoculumBio-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

Matt Hall, Senior Engineer and Senior Project Manager at TerraconFor 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.

When to Use Continuous Monitoring to Resolve Vapor Intrusion Challenges

 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.
