REGENESIS Launches S-MicroZVI

SAN CLEMENTE, CA – (February 13, 2019) REGENESIS, the recognized global leader in in situ soil and groundwater remediation technologies, is proud to announce the launch of S-MicroZVITM.  The new in situ chemical reduction (ISCR) amendment is an innovative, micron-scale, sulfidated zero-valent iron (ZVI) remedial amendment enabling environmental practitioners with a complete solution to quickly and effectively eliminate chlorinated hydrocarbon contaminants on a wide variety of sites. S-MicroZVI promotes the destruction of many organic pollutants and is most commonly used with chlorinated hydrocarbons.  Engineered to provide an optimal source of micro-scale ZVI, S-MicroZVI is easy to use and delivers enhanced reactivity with the target contaminants via multiple reaction pathways. S-Micro ZVI destroys chlorinated contaminants through a direct chemical reaction and also stimulates anaerobic biological degradation by rapidly creating a reducing environment favorable for reductive dechlorination. The launch of S-MicroZVI replaces REGENESIS’ AquaZVI and MicroZVI technologies and introduces a highly effective sulfidated ZVI remedial fluid proven in the field to accelerate contaminant reduction by more than an order of magnitude when compared to commodity iron products.

REGENESIS’ PhD-level scientists developed S-MicroZVI as a glycerol suspension combining micron-scale iron with an iron sulfide surface catalyst, specifically designed to rapidly remove contamination from groundwater and soil.  This proprietary technology results in rapid reduction of contaminants while promoting intrinsic biodegradation. Unlike other remedial technologies, S-MicroZVI can be easily applied, injected under low pressure into the subsurface. The product does not require high pressure “fracking” for application and is applied with ease using readily available equipment.

REGENESIS has spent considerable time testing S-MIcroZVI in laboratory and field studies and it has minimal impacts on groundwater quality, and geochemistry.  Developed by Dr. John Freim, a technical innovator in the development of in situ chemical reduction (ISCR) technologies, S-MicroZVI promises to be the most easily distributed, reactive and cost-effective ZVI product available on the market today. Scott Wilson, President and CEO of REGENESIS, shares “Dr. Freim and the R&D Team have accomplished something quite extraordinary in the development of S-MicroZVI and we are excited about the results we have seen to-date in the lab and testing in the field. The new and improved ZVI amendment addresses the market’s need for a safe, effective and easy to apply ZVI amendment that is proven to be superior at reducing chlorinated hydrocarbon contaminant levels when compared to other approaches.”

REGENESIS, a world-class leader in soil and groundwater remediation technologies, provides safe and effective solutions addressing a wide range of contaminants, including emerging contaminants like PFOS/PFOA.

Industry Expert Spotlight: John Wilson PhD

John Wilson PhD
John Wilson PhD, Principal Scientist of Scissortail Environmental Solutions

When John Wilson, PhD, decided to leave his position as a research microbiologist at the U.S. Environmental Protection Agency and start his own environmental services firm, he chose a name for his company that reflected his spirited commitment to doing things the right way. “I retired from the U.S. EPA in April of 2014”, says Dr. Wilson. “That same month, my wife Barbara and I created Scissortail Environmental Solutions, LLC. Our company is named after the state bird of Oklahoma because the Scissortail Flycatcher is active and alert as it goes about its business, and we try to be the same in all our work.” As the Principal Scientist of Scissortail Environmental Solutions, Wilson, a distinguished REGENESIS Scientific Advisory Board (SAB) member, has transferred a deep reservoir of environmental remediation experience from a highly respected government agency to his own business, creating a comprehensive suite of consulting services for both industry and government. He shares, “Our work focuses on the natural attenuation and active bioremediation of organic contamination in groundwater. The importance of groundwater to economic development and the quality of life in the US will continue to grow as the demand for groundwater increases. We must do everything we can to protect and restore the quality of groundwater.”

Pioneering Remediation Research at the US EPA

Prior to his recent success with Scissortail Environmental Solutions, Wilson was primarily known for his career with the U.S. Environmental Protection Agency, and his work at the Robert S. Kerr Environmental Research Center in Ada, OK. He continues, “From 1979 until I left the EPA in 2014, I worked on bioremediation of chlorinated solvents, and natural attenuation of chlorinated solvents, petroleum hydrocarbons, and fuel components such as MTBE and EDB. At the EPA I helped develop the logic used by the U.S. EPA to implement Monitored Natural Attenuation and to evaluate vapor intrusion from fuel spills.” Now, as the Principal Scientist of Scissortail Environmental Solutions, Wilson divides his time between reviewing the work of others and providing recommendations for improvements and his own applied research. He develops ideas, writes proposals, and does some experimental work, in addition to writing reports. He shares, “I enjoy working with other people to solve problems, and it helps that I like the people I work with. I also have a passion for the work we do.” His career path in environmental remediation originated from an interest in hydrology and from an initial assignment with the EPA that involved exploring the microbiology of groundwater. He continues, “I was originally hired by research managers at the U.S. EPA Office of Research and Development to evaluate whether the aquifers of the United States contained bacteria, and the impact those bacteria might have on groundwater quality. At the time (1978), most engineers and hydrologist thought the deeper subsurface was essentially sterile. I did find bacteria in aquifers and they were doing quite a bit to destroy organic contaminants like TCE and fuel hydrocarbons.”

A History of Accomplishments and Contributions to the Remediation Industry

In addition to his three plus decades of professional experience with the U.S. Environmental Protection Agency, Wilson earned a B.S. in Biology from Baylor University, a M.A. in Microbiology from the University of California, Berkeley, and his Ph.D. in Microbiology from Cornell University. He served an Adjunct Appointment to Rice University from 1990 to 2000, has written more than 80 published journal articles on a wide range of environmentally-focused topics, and has served as a Member of the Editorial Board of Bioremediation Journal. He is currently an Associate Editor of Ground Water Monitoring & Remediation. To stay abreast of trends and new technologies, Wilson often lectures on industry-related topics. “I learn a lot getting ready to teach. In the past I have provided continuing education through the Battelle Conferences and the National Groundwater Association.” Currently, Wilson serves on the REGENESIS Science Advisory Board. He continues, “As an Advisory Board member my job is to make sure REGENESIS doesn’t miss anything as far as the science of their products goes.” He also appreciates the professional relationship that he and Scissortail Environmental Solutions have with REGENESIS. “I enjoy working with them because they combine a strong technical background with extensive practical experience. They understand what I tell them, but they also know enough to evaluate my recommendations against their own unique experience base.” When it comes to applying specific REGENESIS solutions and products to his work, PlumeStop® tops his list. He shares, “If we can learn when to use PlumeStop, where to use it, and how to use it correctly, we can bring a lot of contaminated sites to closure.”

Residing in Ada, Oklahoma, where his firm’s offices are located, Wilson and his wife, Barbara, enjoy the familiarity and pace of a town they have come to know and appreciate through the years. “We are surrounded by good people,” he shares. “We have known most of the people here for a long time.” Outside of work, a favorite hobby includes rock collecting. He continues, “If I can I’ll bring back a rock from each field site I work. When I take road trips, I like to look at the landforms as we drive by and imagine how they came to be. I have a shelf full of the Roadside Geology series of books that I enjoy reading from time to time.” He also volunteers with the local Boy Scout program, an association that he’s enjoyed in Ada for more than 30 years. He continues, “I am on the local District Committee for Boy Scouts, and work with Troop 4 here in Ada. In fact, Barbara and I teach the Sustainability and Environmental Science Merit Badges. All three of our sons are Eagle Scouts.” In addition, he is active in the Rotary Club, and is a past president of his local club.

A Challenging and Improving Industry

When asked about the most demanding aspect of his work, Wilson points out the importance of good writing in his work. He shares, “Writing is hard for me, and it takes me a lot of time and effort to produce something I am ready to send to the client. Early in my career there were no word processors or spreadsheets. I banged out my reports on a manual typewriter, working from handwritten notes of journals that I had read in a library. I drew up figures for journal articles in ink on a drafting table. But today, the modern tools allow me to spend more time actually thinking about what the data means, instead of being involved in the immediate process of producing the manuscript.” And when asked how he’s seen the industry change over the years, he points to an added emphasis on procedures, safety, and performance compared to what he experienced early in his career. He concludes, “There is more process in the process, and much more documentation of procedures. There are also more forms to complete and permissions that must be granted before we do anything. And there is a much greater emphasis on safety, and on the performance and reliability of the systems that we install. Essentially, our industry does a much better of job now than it did thirty years ago.”

REGENESIS is proud to have John Wilson, PhD and Principal Scientist of Scissortail Environmental Solutions, LLC, as a valued partner in environmental remediation, and appreciates his vast expertise and ongoing efforts in providing successful remediation outcomes for REGENESIS and its clients.

Fractured Rock and Eastern Groundwater Conference: A Brief Commentary

Contributed by Dave Peterson, Principal Hydrologist at REGENESIS

Burlington, Vermont is not a bad place to be in late September, and this year I happened to be there for the National Groundwater Association’s (NGWA) Conference on Fractured Rock and Eastern Groundwater Issues.  The uniquely regional focus of this drew a modest crowd of about 300 people including key subject matter experts from the University of Guelph in Ontario and the U.S. Geological Survey (USGS).

Additionally, there was an international group of contributors presenting on investigation sites from a number of regions within a few different countries.  In the context of previous NGWA Fractured Rock Conferences this year there seemed to be a greater emphasis on bedrock groundwater remediation through enhanced bioremediation. A number of other talks presented the use of DFN Analysis (Discrete Fracture Network) as a more realistic approach to understanding and simulating the connectivity of rock fractures, faults and joints in the subsurface. It was also interesting to see how rock cores from various remediation sites are being sent to laboratories to be tested for sorbed contamination held within the rock matrix.

Finally, two of the more critical take-home messages from this conference that I noted are:

  1. Matrix diffusion is a critical issue in bedrock and fractured flow environments since it is primarily one-way into the rock.
  2.  Many porous media hydraulic evaluation techniques are useful for evaluating fractured rock environments.
