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 [...]
Abandoned sites can be damaging to the environment and can lead to expensive cleanups. Take for example the former Dayton Tire and Rubber Facility. In 1987, vandals entered the closed tire and rubber plant to recover salvageable materials. While removing copper cores from electric transformers remaining at the facility, the [...]
Vapor Intrusion, or “VI” occurs when there is migration of vapor-forming chemicals from any subsurface source into an overlying building, negatively effecting the quality of the indoor air. VI quickly became and has continued to be a hot button topic for the environmental consulting field. This is due to the [...]
Historically, the use of Institutional Controls (ICs) was associated with large, complex sites involved in U.S. Environmental Protection Agency (EPA) cleanup programs, such as Resource Conservation and Recovery Act (RCRA) Corrective Action and Superfund. The ICs were commonly used in conjunction with removal actions, soil and groundwater remediation, and risk [...]
Environmental remediation approaches can vary widely for different projects. Based on several factors (potential contaminants, exposure pathways, lithology at the Site, neighboring properties, project stakeholder risk tolerances, timing goals, etc.), there are numerous remediation alternatives to explore. Does the Site require active remediation such as excavation and off-Site disposal or [...]
At the time of writing this article, Joe Biden is projected to be the 46th President of the United States of America. On January 20, 2021 he will take the oath of office and begin his presidency. How will a Biden-Harris administration govern? Will this be a return to Obama [...]
