Book excerpt: A Problem Confirmation Study was performed at three sites on Mather AFB identified in the Phase I investigation as requiring further study (the Air command and warning Area, the7100 Area, the West Ditch) and the Northeast Perimeter. The field investigation was conducted from February 1984 to June 1985 and included installation of 11 monitor wells, collection of groundwater samples from the monitor wells and 15 base production wells, and collection of sediment samples from two locations on the West Ditch. Analytes included oil and grease, TOC, volatile organic compounds (VOA), as well as dimethylnitorsamine, phenols, pesticides and dissolved metals at some specific sites. Based on the hydrogeologic complexity of the physical setting and the findings of the sampling and analytical work, follow-on investigations have been recommended at all three sites.
