In several states, it is common practice to use an institutional control, such as a land use restriction, or an engineering control such as a protective barrier, to achieve regulatory closure for a property. The existence of these controls should be a clear indication to potential purchasers that contamination has [...]
You’ve been through a Phase I Environmental Site Assessment (ESA) and Phase II Investigation process, and it has identified contamination above regulatory criteria on the property you are planning to purchase. What do you do now? A “facility” (Part 201) or a “property” (Part 213) is defined by Michigan’s cleanup [...]
Tungsten (represented on the periodic table as “W”) is a naturally occurring element that exists in the environment as minerals with the two most common minerals being Wolframite and Scheelite. Due to tungsten's unique properties, such as its remarkable tensile strength, conductivity, and melting point, it can be found in [...]
There are several factors that should be taken into consideration when evaluating recognized environmental conditions (RECs) during a Phase I Environmental Site Assessment (ESA). RECs are found on industrial and commercial properties for a variety of causes. This webinar will dive into what is evaluated to determine RECs, their potential [...]
Cleaning up contaminated properties can take a long time and be a great expense. In most cases, conducting a completely “clean” cleanup is not always feasible and can be cost-prohibitive. As a result, risk-based closures are becoming more common, which means residual contamination remains behind and environmental restrictions are applied [...]
Remediation of soil and groundwater, and more generally, re-use of Brownfields, has come a long way over the last 40 years since the introduction of the various State and Federal cleanup programs. Cleanups have gone from excavating soil and pumping & treating groundwater, to advanced in-situ chemical, biological, and mechanical/electrical [...]
Are you considering purchasing a commercial or industrial property that may have environmental contamination? It is critical to consult with a qualified team that can provide you with a full evaluation of risks that typically accompany the purchase and redevelopment or reuse of the contaminated property. Learning the difference between [...]
ProUCL, a statistical software package developed by the USEPA, is a very powerful tool for evaluating environmental datasets. This webinar will discuss the applicability of ProUCL to environmental datasets, including its use in establishing background levels, determining exposure point concentrations, evaluating trends in monitoring well datasets over time, determining outliers [...]
What do non-stick coated pans, waterproof fabrics, oil-resistant food packaging, stain-resistant materials, and fire-fighting foam all have in common? They all potentially contain fluorinated compounds, and more specifically, are made with a suite of specialty chemicals called Perfluorooctanesulfonic acid (PFOS) and Perfluorooctanoic acid (PFOAs). PFOS and PFOAs both are fluorinated [...]
Vapor Intrusion (“VI”), or the migration of contaminant vapors from soil and groundwater into overlying structures, has been a significant topic in the environmental world for over 20 years. Common contaminants associated with VI are volatile organic compounds (VOCs), which include gasoline constituents, such as benzene, and industrial degreasing and [...]
