Basewide Groundwater Operable Unit. Groundwater Operable Unit RemedialInvestigation/Feasibility Study Report. Volume 1

摘要

This document presents the Remedial Investigation/Feasibility Study (RI/FS) forthe Groundwater Operable Unit (GW OU) at McClellan Air Force Base (McClellan AFB). The RI/FS is one step in the GW OU, which is intended to develop an interim remedial action for groundwater contamination at McClellan AFB. The preferred interim remedial action for the GW OU is containment of the 0.000006 risk target volume, treatment using air stripping with vapor phase carbon and LGAC polishing on the east side, the existing GWTP on the west side, and injection of the treated water.
