Remediation Technologies to Address Chlorinated Solvent Contamination

Chlorinated solvents like tetrachloroethene (PCE) and trichloroethene (TCE) are man-made chemicals typically used in industrial applications, such as metal de-greasing or dry cleaning. When introduced to the environment through historical or current activities (e.g., waste management practices, manufacturing processes, spills, etc.), chlorinated solvents can lead to persistent contamination of soil [...]

PFAS – Looking To The Future

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 [...]

Negotiating On-Site Access For Vapor Intrusion

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 [...]

Ohio’s Cessation of Regulated Operations Program

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 – Beware of Biased Results

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 [...]

Use of Institutional Controls to Facilitate Site Closure

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 [...]

Electric Resistance Heating (ERH) Remediation Case Study

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 [...]
