Performance of in-situ soil and groundwater treatment systems at McClellan Air Force Base
- BDM Federal, McClellan AFB, CA (United States)

McClellan Air Force Base (AFB), located near Sacramento, California, is one of the Strategic Environmental Research and Development Program`s National Environmental Technology Test Sites. The US Air Force has evaluated, as part of the on-going environmental clean-up of McClellan AFB, several innovative and conventional in situ soil and groundwater technologies for the treatment of volatile organic compounds. This paper presents an overview and comparison of the performance and cost of three innovative technologies tested at McClellan AFB. Conventional groundwater extraction systems are effective but costly. Operation and maintenance (O and M) costs for treatment systems are increasingly becoming a major component of the environmental clean-up budget. The performance, limitations, costs, and lessons learned from the implementation of conventional soil vapor and groundwater extraction systems are compared with those of two innovative dual phase extraction systems. Both the Xerox 2-Phase{trademark} Extraction system and a standard dual phase extraction system are more effective than their conventional counterparts, but only over a discrete range of soil permeabilities. Discussions on McClellan AFB`s experiences with cometabolic bioremediation of groundwater and thermally enhanced soil vapor extraction systems are also included.
