The BBC will work at Site 32 under the auspices of the Federal Facilities Agreement (FFA) between the U.S. Air Force (USAF), Pease Development Authority (PDA), USEPA and NHDES. Pease International Tradeport is underlain by a cover of interfingering sand, gravel and marine clay. The deposits typically vary in thickness from 1 to 15 meters. Under these unconsolidated sediments lies well-layered,tightly folded quartzites and phyllites of Silurian (or older) Kittery and Eliot Formations. these rocks are variably faulted, fractured, and intruded by Devonian and younger igneous rocks. The most common of these in the study area are northeast-trending Mesozoic mafic dikes.

• Fractured Bedrock

The plume extends approximately 0.5 kilometers and has migrated with the groundwater into the weathered and competent bedrock.

Source containment and continued groundwater monitoring has been implemented at Pease by the U.S. Air Force at site 32. The Bedrock Bioremediation Center works at site 32 under the auspices of the U.S. Air Force.

The base was closed as an active installation on March 1991. The Air Force has continued environmental restoration efforts since the base was closed. With the construction completion of the Site 49 remedy in the Summer of 2000 , all construction activities for the Pease AFB NPL site have been completed. O&M and LTM activities will be required at many of the sites where remedies have been implemented.
