Abstract : Twelve sites were investigated at Elmendorf AFB during the Phase II, Stage 2 field evaluation of the IRP. The sites were investigated through the drilling, installing, and sampling 11 new monitor wells, three base water supply wells, and four surface water samples. Two ground water systems exist beneath the base, and they are typically separated by a thick clay unit. The depth to water table varies from zero to as much at 50 to 60 feet. The shallow aquifer has been contaminated in the past and is vulnerable to future contamination, but the deeper aquifer is not in significant danger. The principal source of water for the base and the adjacent City of Anchorage is surface water upstream of the base; makeup wells generally extend to the deep aquifer.
