AeroVironment Inc. conducted a Phase II, Stage 3 IRP Survey at Mather AFB in Sacramento, California. The objective of this survey was to confirm and quantify the presence and extent of contamination at the 7100 Disposal Area, Air Command and Warning (ACW) Area Disposal Site, West Ditch and in the Northeast Perimeter of the base. These sites had been invesigated in 1985 during a Phase II, Stage I Survey and additional work was recommended for all four. During Stage 3, thirty-five groundwater monitoring wells were installed, using standard mud rotary techniques. Seventeen were drilled into the water table aquifer and 18 into the confined aquifer. Two rounds of groundwater samples were collected from 35 Stage 3 wells, 1 Stage 2 well, and 8 Stage 1 wells. One round of samples was collected from base production wells. A geophysical survey and a soil gas survey were also conducted at the ACW and 7100 sites.
