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.

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.

Over the course of her career, Amy Roth, Associate Vice President and Senior Geologist at Wilcox & Barton, Inc., has clearly established herself as an expert in the field of environmental remediation. With a background that includes several positions, such as Project Director, Senior Geologist, and Operations Manager, among others, Roth has been exposed to a broad spectrum of the environmental sciences industry, and in the process, has helped shape the continued growth of Wilcox & Barton, Inc. In her current role, Roth manages and provides technical direction for the firm’s Massachusetts-focused environmental scientists and engineers. “I also direct and/or manage larger projects,” she says, “I act as the Licensed Site Professional (LSP) of Record for a wide range of sites and clients. I enjoy digging into the details of a project and helping people work through the technical and regulatory challenges.” Learn more about Amy Roth in our client spotlight.

Upcoming Webinar on Reducing Exposure to PFAS

Ginny Yingling is a Senior Hydrogeologist in the Environmental Health Division of the Minnesota Department of Health. She works with a team of Health Risk Assessors to evaluate human exposures to harmful chemicals in drinking water related to man-made contaminated sites. Since 2003, she has been the agency’s lead investigator of per- and polyfluoroalkyl substances (or PFAS). She has a B.S. from Penn State, and a M.S. from the University of Wyoming, both in Geology, and has over 25 years of experience working on contaminated sites. Ginny is also the co-chair of the Interstate Technology and Regulatory Council’s PFAS Team, a group of over 390 environmental professionals drawn from state and federal agencies, academia, industry, consulting, and public interest groups. The team has developed a series of seven fact sheets on PFAS, conducts PFAS training events, is developing a PFAS risk communication tool-box, and is preparing a detailed report on the current state of knowledge regarding PFAS.

Dr. Kristen Thoreson is the lead inventor of PlumeStop® Liquid Activated Carbon™. She heads the chemical research and product development program at REGENESIS. Her team is focused on developing advanced technologies for the treatment of recalcitrant compounds in mixed environmental media. She is trained as a chemist, and her graduate and post-doctorate research focused on mechanistic investigations of chlorinated ethene degradation pathways using molecular models and compound specific isotope analysis (CSIA) for both biotic and abiotic systems. She obtained her BSc in chemistry from the University of Wisconsin – La Crosse, and her PhD in inorganic chemistry from the University of Minnesota. She also spent time as a postdoctoral associate at the Helmholtz Zentrum in Munich, Germany as a part of the Research Unit for Environmental Organic Isotope Chemistry.
