The United States Air Force at McClellan Air Force Base AFB, in coordination with United States Environmental Protection Agency EPA Superfund Innovative Technology Evaluation SITE Program initiated this study to supplement information contained in the Draft Innovative Technology Evaluation Report ITER EPA, 1995 and other reports prepared for evaluating the application of 2-Phase ExtractionTM 2PE, soil vapor extraction SVE and pump and treat PT technologies. Groundwater is contaminated with trichloroethene TCE, tetrachloroethene PCE and FreonR 113 and lesser quantities of other volatile organic compounds VOCs. A SITE demonstration of 2PE was conducted at McClellan AFB over a six-month period from August 1994 through January 1995. The demonstration was conducted in an existing well previously used for extracting contaminated groundwater using a PT system. An SVE system was later implemented in nearby vapor extraction wells. The purpose of this report is to present evaluation of each of these technologies so that the lessons learned can he applied to similar sites requiring remediation. Included in this report are models of the zone of vacuum influence of SVE and 2PE, models of the groundwater cone of depression of PT and 2PE, and cost estimates for implementation of these technologies.
