Client Spotlight: Adam Heft, Senior Geologist at WSP,^® LLC

When you ask Adam Heft, Senior Geologist at WSP, a leading professional services firm and valued REGENESIS client, what he enjoys most about his work, he is quick to point out how much he appreciates the variety of his responsibilities. Says Heft, “I am involved in all phases of my projects – from working with a prospective client on a proposal, to conducting the required investigatory work, and preparing and submitting reports to regulators and clients. There is plenty of variability, and I am still able to get out of the office to perform field work. I’m quite fortunate because many senior level individuals do not have that flexibility.” In our client spotlight, he shares his passion for geology and working toward successful remediation outcomes.

Client Spotlight: Bruce Savage, Vice President, Director of Environmental Services at Geotechnical Consultants

For Bruce Savage, Vice President, Director of Environmental Services at Geotechnical Consultants, Inc. (GCI), a leading full-service, geotechnical engineering and environmental consulting firm, motivation comes easy in fulfilling his day-to-day responsibilities. At GCI, a valued Land Science® client, Bruce enjoys the satisfaction of working with clients to determine where concerns exist, and then develops and implements workable, cost-effective remedies that satisfy all parties. He achieves optimum results by working closely with real estate developers, property owners, their business partners and regulatory personnel to identify environmental contamination and the appropriate steps to remedy contamination. In our client spotlight, he shares the path that lead him to the field of vapor intrusion mitigation, and how he keeps pace with a fast-changing industry.

Multi-layered Vapor Barrier for New Building Construction

Vapor Intrusion Barriers need to balance two key characteristics, chemical resistance (how well the barrier protects against the chemical of concern) and constructability (the ability to effectively seal all entry pathways in a building).

Geo-Seal is a composite system that creates the ideal blend between constructability and chemical resistance by using both high-density polyethylene (HDPE) and spray applied asphalt latex. Ideal for new construction, Geo-Seal has been accepted by state environmental agencies across the country, the US NAVY, US AIR FORCE, Fortune 500 Companies, and leading environmental consulting firms around the world.

Upcoming Webinar

Demonstrating Contaminant Biodegradation in Conjunction with PlumeStop® Liquid Activated Carbon™

Join us for a special remediation webinar presentation with Dora Taggart, President of Microbial Insights, Inc. Her presentation will focus on case studies where molecular biological tools (qPCR and QuantArray®) were used to investigate the impact of PlumeStop Liquid Activated Carbon injections on key halorespiring bacteria and anaerobic biodegradation at chlorinated solvent sites. This live webinar starts Tuesday, July 25th, 2017 at 11am pacific/2pm eastern.

Client Spotlight: Matthew Burns, Technical Fellow at WSP

From in situ remediation lead and technology expert, to published author and guest lecturer, Matthew Burns, Technical Fellow at WSP USA, the U.S. operating company of one of the world’s leading engineering and professional services firms—WSP and valued REGENESIS® client, has garnered an exceptional range of environmental industry experience. Burns started at WSP in 1999, and after working his way through various positions involving support and project management, began focusing his responsibilities on bringing in situ chemical and microbial processes, as well as diagnostic expertise, to project teams in the U.S. and globally.  In addition to being Technical Fellow at WSP, Burns is also the in situ remediation practice lead and the technology innovation lead for WSP’s environmental business.

Eliminate Risk and Uncertainty with PlumeStop

PlumeStop® Liquid Activated Carbon™ is a break-through groundwater remediation technology that reduces dissolved phase contaminant plumes in days. The key innovation with PlumeStop is that it is composed of extremely fine particles of activated carbon (1‐2μm) suspended in water through a proprietary dispersion chemistry developed by the REGENESIS R&D Department.This allows the technology to flow into the subsurface at low pressure and achieve consistent, reliable distribution – a capability unlike any other form of activated carbon used for groundwater remediation today. As a result, environmental professionals gain a certainty that the contaminants have been removed throughout the entire treated area. It also secures complete biodegradation of contaminants, and continually regenerates its sorptive capacity, allowing for long term treatment.

Multifunctional Amendments and Site Characterization Effectively Manage Back Diffusion from a Fractured Sandstone Aquifer

Join us for a special vapor intrusion webinar presentation with Matthew Burns, Technical Fellow and the in situ remediation Practice Leader for WSP. He will present a case study of a site where multifunctional amendments were applied to manage back diffusion of chlorinated VOCs from a fractured sandstone aquifer. This live webinar starts Tuesday, June 27th, 2017 at 11am pacific/2pm eastern.

Client Spotlight: Jeffrey Carnahan, MS, LPG
Executive Vice President of EnviroForensics

Throughout his 20 year career in environmental consulting, Jeff Carnahan has remained true to his goal to understand and focus on the needs of his clients. While his current position as Executive Vice President of EnviroForensics®, a leading environmental engineering firm, garners much of his time, Jeff still puts a priority on providing personalized client service. It’s a combination of successfully solving client challenges and honing his scientific, regulatory and management skill-set that continues to separate Jeff from his peers. It also is one reason why EnviroForensics, a REGENESIS® client, continues to excel in all phases of environmental engineering. Shares Jeff, “Because my true passion is science, I’ll probably never stop working in the day-to-day, hands-on area of environmental remediation.”

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 through to harmless end products such as ethene and ethane. It is highly compatible with a range of electron donors.

Client Spotlight: Lori Riker, Senior Project Manager, Benchmark/Turnkey

Throughout her university studies, Lori Riker, Senior Project Manager at Benchmark/Turnkey, developed a drive and curiosity that would help shape her career. Her degree in Civil Engineering, from the University of Waterloo, with a Water Resources major, proved to be a catalyst and led her to a graduate degree that, at the time, was aimed at a new field that was just beginning to attract interest. She also chose to research and write her thesis on a new soil remediation technique that she found intriguing. By the time Lori completed her Master’s in Environmental Engineering, her leadership abilities and commitment to the environmental industry were readily apparent, and have continued to play a key role throughout her career.
