    2/11/2015 · Plants & Trees
    Anyone who has a home with trees around it will someday need to remove dead or dying limbs and trees. The best managed landscaping requires trees to be pruned or removed as they grow. In addition, storms often create dangerous situations as limbs and trees are broken or bent over. I remember living on Lake Martin in Alabama during Hurricane Opel. The storm hit at night and we sat in the basement listening to all the commotion and guessing what was happening to our home. Occasionally, I would go up to the main floor with a flash light (power was toast) and peer out the windows trying to assess the damage. One time I reported to my family that the porch roof was gone. The porch faced the lake and the direction of the wind. It had rained all day before the hurricane winds hit causing the soil around the trees that separated our home from the water to soften up. At day light we found all the lakeside trees pushed over onto our roof.

    .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.

    Mr. Schroeder's training at one of the finest engineering universities in the United States formed the basis for his uncompromising, thorough, and thoughtful approach to projects. 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 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. He has assisted them 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.

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 maintains his role as an adjunct professor. He has also published articles in a number of trade journals on environmental due diligence.

    Joel R. Coats, et al. (editors)
    Resistance to conventional pesticides has been growing rapidly among all pests. Furthermore, there is increased public concern about the safety of conventional pesticides, and increased governmental restrictions have resulted in the need to identify new compounds that are safe and effective in controlling pests that are of concern to agriculture as well as to public and animal health. Biopesticides may aid in the control of such pests with fewer deleterious effects to the environment, people and animals.

    Polycyclic aromatic hydrocarbons (PAHs) are the first type of chemicals that were ever discovered to cause cancer in humans. They are found in cigarette smoke, in barbecued and smoked foods, in automobile and Diesel engine exhaust, fireplace smoke, and many other common things that people are exposed to. Analyzing for PAHs in the environment is important in identifying potential sources of cancer exposure and eliminating these as risks.
