EXPLANATION OF SIGNIFICANT DIFFERENCES SITE 8 - FIRE DEPARTMENT TRAINING AREA #2 PEASE AIR FORCE BASE NPL SITE
U.S. Air Force, 11 pp, 2019

This ESD provides U.S. EPA and the New Hampshire Department of Environmental Services with a description of and the rationale for the U.S. Air Force's proposed addition of a groundwater extraction and treatment system (GWETS) to the existing corrective measures for Site 8, Fire Department Training Area #2. Site 8's previous use for fire training activities from 1961-1988 led to PFOS and PFOA contamination in groundwater in areas where aqueous film-forming foam was used. Groundwater assessments in 2014 identified PFOA and PFOS at levels above the EPA 2009 provisional health advisories both on base and in private drinking water supplies. In response, U.S. EPA issued a Safe Drinking Water Act Administrative Order for the Pease Air Force Base in July 2015 that led to the GWETS construction. The system consists of multi-bag filters and liquid-phase granular activated carbon and four ion exchange resin vessels to remove PFOS and PFOA from the extracted groundwater. A long-term operating and monitoring plan requires the collection of groundwater elevation, PFAS concentration, and treatment system operational data to assess the performance of the GWETS to meet hydraulic containment and treatment objectives. https://semspub.epa.gov/work/01/100011058.pdf
