    In developing a vacant piece of land, steep slopes are often an issue. And, the more prevalent the steep slopes are on a site, the greater the likelihood that retaining walls will be part of the Approved Site Plan. Let us consider three municipalities which regulate the final allowable slopes for land which is filled, cut, or graded

  • Michael Sklash Hydrogeology Expert PhotoMichael Sklash, PhD, PEng, Senior Hydrogeologist at Dragun Corporation, has over 40 years of experience in solving complex Groundwater Problems. Dr. Sklash uses a wide range of tools including environmental isotope tracing, high resolution site characterization, and groundwater modeling to develop robust conceptual site models for site remediation, and litigation purposes.

    Dr. Sklash's research from the 1970s through the 1990s led him to become world renown in his field of Isotope Hydrogeology. It is now a keystone in the understanding of how groundwater interacts with streams, and his publications are frequently termed “bench mark.” During his academic days, Dr. Sklash 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.

    Dr. Sklash uses 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. He 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.

His “no stone unturned” philosophy to each and every project is expected of environmental engineers, but not always delivered. Mr. Schroeder's experience includes time spent 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 extensive experience in assessment and remediation of chemicals associated with vapor intrusion (TCE, PERC, etc...). He also has designed groundwater remediation to address PFAS. Matt has published in international, scientific, and legal journals.

    With a keen eye toward detail and a customer-centric focus, Mr. Schroeder has won the admiration and appreciation of several long-term clients.

His assessment of commercial industrial properties across North America pre-date the environmental due diligence framework. It was Mr. Bolin's insightful approach to environmental due diligence that earned him recognition as an “Elite” provider of services by a real estate publication.

    Mr. Bolin is routinely asked to share his knowledge by teaching other professionals at seminars, and he was previously a an adjunct professor. He has also published articles in a number of trade journals on environmental due diligence, vapor intrusion, conceptual site models, and more.
