Cleanups at Federal Facilities

Emerging Contaminants and Federal Facility Contaminants of Concern

Technical and Emerging Contaminant Fact Sheets

EPA published the following technical fact sheets, which provide brief summaries of contaminants of concern that present unique issues and challenges to the environmental community and EPA at contaminated federal facility sites. Each fact sheet provides a brief summary of the contaminant, including physical and chemical properties, environmental and health impacts, existing federal and state guidelines, and detection and treatment methods. These fact sheets are intended for project managers and field personnel to use when addressing specific contaminants at cleanup sites and are updated annually to include timely information.

Additional Information

Perchlorate Resources

Perchlorate is used in a wide range of applications, including military munitions (mortars, flares, grenades), solid rocket fuel, pyrotechnics and fireworks, blasting agents, matches, air bags, and certain types of fertilizers. It has been detected in the ground water at 54 federal facilities and 29 private (Superfund or RCRA) sites in 26 states. EPA and states are addressing the contamination at many of the sites through investigations and response actions (e.g., blending, providing alternative water supplies, remediating ground water contamination) or through enforcement actions against potentially responsible parties (PRPs).

Vapor Intrusion

Vapor intrusion (VI) also is being examined as an emerging contaminant because of concerns about the VI pathway. Vapor intrusion generally occurs when there is a migration of volatile chemicals from contaminated ground water or soil into indoor air spaces of overlying buildings.
