New Focus Area: Chlorinated Solvents

Posted: March 22, 2023

Chlorinated solvents have been used for a variety of commercial and industrial purposes, such as degreasers, drycleaning solutions, paint thinners, herbicides, pesticides, resins, glues, and a host of other mixing and thinning solutions.

New Focus Area: Polycyclic Aromatic Hydrocarbons (PAHs)

Posted: March 7, 2023

PAHs are formed by the incomplete combustion of coal, oil, gasoline, garbage, residential wood burning, and other organic materials. They are are one of the most common contaminants of concern (COC) addressed at Superfund sites, particularly in soil.

New Focus Area: Chromated Copper Arsenate (CCA)

Posted: March 7, 2023

CCA is a pesticide that has been used as a preservative in pressure-treated wood since the 1940s. Manufacturers have voluntarily discontinued its use in pressure-treated wood for residential use. CCA is still used in products such as utility poles, pilings, docks, and retaining structures.

Superfund Remedy Report, 17th Edition

Posted: January 30, 2023

The U.S. Environmental Protection Agency’s (EPA) Office of Superfund Remediation and Technology Innovation prepared the Superfund Remedy Report (SRR) 17th Edition to share analyses of remediation technologies selected to address contamination at Superfund sites. EPA is particularly interested in documenting and disseminating information on treatment technologies to advance its mission of protecting human health and the environment. The report focuses on treatment as the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) establishes a statutory preference for treatment.

New Focus Area: Geophysical Methods

Posted: January 10, 2023

Geophysical methods measure physical properties of materials that can be used to infer information about the surface and subsurface of the Earth. These minimally invasive to non-invasive methods support the characterization and remediation of contaminated hazardous waste sites. Geophysical methods provide both quantitative and qualitative information.
