Superfund record of decision amendment (EPA region 9): Williams Air Force Base, operable unit 2, Chandler, AZ, August 16, 1996
Technical Report

OSTI ID:464256
Williams Air Force Base (AFB) is located in Maricopa County, east of the city of Chandler, Arizona. This record of decision amendment (RODA) selects a remedial action (RA) for site cleanup of the deep soil (from a depth of 25 feet to the top of groundwater) at ST-12. Extensive testing and modeling conducted as part of the OU-3 FS showed that contaminants in deep soil could travel to groundwater and impact the cleanup remedy selected for groundwater in the OU-2 proposed plan. For this reason, the decision was made to consider all the environmental media at ST-12 as a unit in subsequent studies. Deep soil at ST-12 is, therefore, reincorporated into OU-2.
