Read about Michael Sklash here.

His research from the 1970s through the 1990s led Mike to become world renown in his field of isotope hydrogeology as he challenged conventional thought on storm runoff generation. His research became a keystone in the understanding of how groundwater interacts with streams, and his publications are frequently termed “bench mark.” During his academic days, Mike was a visiting scientist in many places around the world, including: New Zealand, Australia, England, China, India, and Africa. He was a consultant to the USEPA and Atomic Energy Canada Limited, among others.

Looking for more challenging problems to solve, Mike joined Dragun in 1988. Since then, he has used his skills to untangle complex, and often confusing, groundwater problems and put them in “order” so a remedial plan becomes obvious or a Court can see the way.

Mike has led the technical team on many of Dragun’s most challenging projects, including: the groundwater nexus issue in a wetlands dispute that went to the U.S. Supreme Court (Rapanos); avoiding expensive remediation at a complex TCE-impacted site in Michigan acquired by the Norwegian global aluminum manufacturing company Norsk Hydro; and recently successfully challenging the remediation plan of the US Army Corps of Engineers at a Cold War legacy site in Kansas. Mike has also helped many attorneys, local entrepreneurs, and municipalities with their environmental problems.

In a very recent court case, an exasperated, opposing attorney rhetorically asked: “How can you be so sure about everything?” Mike didn’t answer, but it has to do with his passion for getting things right the first time.

Expertise: Litigation support, groundwater modeling, environmental isotope tracing, and other techniques required to characterize a site so that the best remedial option can be implemented.

Matt was fortunate because his early career path was formed by spending time performing field investigations, inspecting landfills, and observing both simple and complex tank removals and site remediation efforts. Over the last two decades, he has developed a unique ability to integrate complex soil and groundwater data to perform feasibility studies and design and implement remediation. Matt has published in international, scientific, and legal journals. With a keen eye toward detail and a customer-centric focus, Matt has won the admiration and appreciation of several long-term clients. They know Matt will provide them with the best possible advice, keeping at the forefront their objectives and concerns. He has assisted his clients with site closures, solved their environmental permitting and planning issues, counseled them on delisting petitions, represented them in regulatory negotiations and in court, and provided soil and groundwater remediation solutions. Expertise: Soil and groundwater remediation, groundwater modeling, environmental compliance, vapor intrusion evaluation, litigation support.

As with many of Dragun’s senior environmental advisors, Chris has spent most of his career with Dragun. His career path has covered a multitude of environmental projects, including a precedent-setting project that culminated in a favorable Michigan Supreme Court ruling.  Chris’ experience includes underground storage tank closures, landfill investigations, groundwater supply evaluations, contaminant investigations, and environmental permitting for livestock operations. Regardless of the issue, Chris brings the same passion and practical application of the geological sciences to the understanding of site conditions. Chris is also a frequent author and has written articles for several publications in the United States and Canada. Chris’ focus is on finding solutions for his clients, and his dedication has paid dividends. As way of example, one project where Chris was the senior advisor, his client battled misguided state regulators all the way to the State Supreme Court. With Chris’ thorough assessment and understanding of the groundwater, which included several co-mingled plumes, his client won a significant seven figure settlement against the State. On another project, Chris used his hands-on regulatory knowledge to guide one of the nations’ most influential agricultural organizations to find a solution to a significant environmental regulatory challenge Expertise: Decommissioning activities and remedial investigations of petroleum sites, industrial facilities, dry cleaners, and chemical and petrochemical facilities; Phase I ESAs and Phase II ESAs and Litigation Support.

About our Founder – Dr. James Dragun

Dr D1949 – 2015 In 1988, with great passion, scientific acumen, and conviction, Dr. James Dragun founded The Dragun Corporation.  Shortly after he established the company, he released his first book, “The Soil Chemistry of Hazardous Materials.”  He would later go on to author or co-author many more scientific tomes including, “Elements in North American Soils” and “Natural Chemicals in Sediments.” A native Detroiter, Jim completed his undergraduate work at Wayne State University in Chemistry, moving next to Pennsylvania State University where he earned a Master’s and Ph.D. in agronomy at his beloved Penn State.  The university recognized Jim’s accomplishments in 2005 when the Department of Agronomy awarded him with the Distinguished Alumni Award. Upon graduation from Penn State, Jim served with the United States Environmental Protection Agency (EPA) in Washington D.C. Over the course of the next five years, Jim would work on some of the nation’s highest-profile environmental projects. It was while working for the EPA that Jim became convinced that a sound, scientific understanding of contaminants and how they behaved in the environment was lacking from many of the scientific assessments that he reviewed. Realizing that his nature did not lend itself to be a government bureaucrat, Jim soon found himself working for environmental consulting firms in California and then back in his home state of Michigan later on. What Jim discovered during his time working for consultants was he wanted to approach projects differently than through industry standards. He believed that consulting meant solving problems as quickly as possible. As Jim was fond of saying, “We get you out of trouble, we keep you out of trouble, and we don’t make trouble.” Over the course of the next nearly 30 years, Jim earned a well-founded reputation as one of the premier scientists in the environmental consulting community, known for his disciplined, scientific approach to solving complicated, environmental issues and conducting tough-as-nails regulatory negotiations. Jim was also a frequent lecturer in both the United States and Canada. Jim’s expertise in soil chemistry reached China, Europe, and the Middle East, where he was also invited to teach. Jim’s scientific rigor carried over into the hand-selection of his team of scientists, engineers, accountants, and other staff members. He insisted that his “team” jealously guard the reputation of the company that bore his name. In 2012, as Jim opted for semi-retirement and to pursue additional interests, he handed over management of the company to his trusted team, most of which had worked at Dragun Corporation for 25 years or more. That team continues to operate the company today with great deference to a strong foundation that Jim established and maintained throughout his lifetime. That legacy lives on.


“I have been impressed with the technical knowledge that Dragun has brought to this project…The end product has always been first rate. I wish to commend Dragun staff personnel at all levels, who are highly professional, but also friendly and a pleasure to deal with.” – Elizabeth Main, Attorney, Dickinson Wright
