  • 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.

    The use of synthetic field turf or grass on athletic and recreational fields has increased significantly over the last 40 years primarily because of their durability and low maintenance. However, agency reports and published literature have heightened the public awareness of the potential health risks associated with the chemical constituents present in these synthetic fields.

    Hazardous waste is a waste with properties that make it potentially dangerous or harmful to human health or the environment. The universe of hazardous wastes is large and diverse. Hazardous wastes can be liquids, solids, or contained gases. They can be discrete chemical compounds, mixtures of compounds, or simply have some property that makes them hazardous. In regulatory terms, a hazardous waste is a waste that appears on one of the four RCRA (Resource Conservation and Recovery Act) hazardous wastes lists (the F-list, K-list, P-list, or U-list) or that exhibits one of the four characteristics of a hazardous waste - ignitability, corrosivity, reactivity, or toxicity.

    In 2002, a violent explosion from inside the basement of a ten-story building in New York City hospitalized 31 people (four critically) and caused extensive damages to the masonry structure. The blast dislodged portions of the basement ceiling and inside walls, collapsed the concrete stairwells and portions of the elevator shaft, and shattered glass windows five stories above ground

    Many vehicular accidents happen because drivers are in too much of a hurry or they are distracted by any number of things. They just are not paying close enough attention to their surroundings. Traffic accidents at signalized intersections are common where both drivers claim the other driver is at fault.

    When selecting projects under a limited budget, a firm should implement the project that will return the most value. Ultimately, firm value is measured by stock price, which can be impacted when the firm makes a major announcement. This paper shows that announcements of energy management projects correlate with a 21.33% increase in stock price within 150 days of the announcement. This increase is in addition to the risk-adjusted return the firm would normally experience . For example, during a "bull market" a firm's expected return was 10%. After the announcement, the return would increase by 21.33%, for a net return of 31.33%. These results suggest that investors react positively to energy management projects. This outcome demonstrates one more strategic incentive for firms to implement energy management projects.

    As a new US government administration comes into control, many people have asked me if I am optimistic about energy efficiency projects... the answer is YES. No matter how you analyze it, energy efficiency is a great investment... dare I say "Huge". Energy efficiency projects have high returns on investment and extremely low risk. The only thing they don't have is a "compelling event" forcing them to get done. In contrast, a repairing a roof leak has a sense of urgency because of potential damage from inaction.

    About five years ago, I wrote about project developer who specializes in energy tax deductions and rebates. We call him "Dr. EPAct" because he knows how to navigate and attain substantial tax deductions and rebates, which pay for most (if not all) of a project's cost. His highly tangible skills in accounting are typically "outside" of an energy manager's core strengths, but definitely worth knowing. This month, Dr. EPAct (Bill Bissmeyer) is contributing again in this article! He will help explain the Federal Tax Extenders Act, which was signed on December 18, 2015 into law. More importantly, Bill presents a case study showing the economics and tax advantages that you have available to you. Frankly- you cannot afford to skip this article because it may be the key you need to get your project funded.

    Previous research indicates there are additional (often unreported) benefits from saving energy.1,2 This paper identifies these "additional benefits" and describes how to calculate their value.3,4 In addition, we found a high percentage of facility managers experienced some of these benefits. For example, in a recent survey, 92% of facility managers experienced reduced maintenance material costs as a result of energy conservation (primarily because lights, filters and other equipment lasted longer when operated less hours per year).

    You think you're about to be a hero by entering into an Energy Savings Agreement, (which is supposed to fund improvement projects based on savings). Your long-time law firm reviewed the contracts, and your engineers have signed off. Everything seems positive. So what can go wrong? Actually, quite a bit... and your knowledge can be the difference between having a glowing success or abject failure that could cost you a job, reputation or worse.

    The landscape for implementing energy efficient projects is rapidly changing and the need for energy project financing has never been greater. This book provides the key success factors for structuring a finance energy project and getting it approved by top management. Part I covers the need for financing as well as the basic concepts. Part II covers some practical applications of financing such as performance contracts, power purchase agreements, and other items like PACE financing. Part III contains articles that have helped many engineers get more projects implemented as they include information that can be used to present projects and get them approved.

    Meeting a need in the marketplace for information on how to operate a sustainable facility and reduce carbon emissions, the Green Facilities Handbook clearly explains why green business is good business and delineates practical strategies to green your operations in energy and management. The book explores issues in the greening of a facility, including janitorial considerations, fuel choices for fleets, and recycling. Additional information is provided on carbon reduction terminology, monitoring and reporting, and carbon trading as well as offset strategies. Special bonus chapters include valuable information on financing and procedures for “green” marketing.
