Book excerpt: A low-cost and innovative soil vapor extraction (SVE) system using modified internal combustion engines (ICEs) to extract and destroy fuel hydrocarbons is successfully remediating a large JP-4 jet- fuel-contaminated site on Davis-Monthan Air Force Base (DMAFB), Arizona. Based on previous site investigations, soil contamination extended from near the ground surface to a depth of approximately 260 feet below ground surface (bgs). A maximum total fuel hydrocarbon concentration of 320,000 milligrams per kilogram (mg/kg) and a maximum soil gas hydrocarbon vapor concentration of 140,000 milligrams per liter (mg/L) were measured at the site. Prior to installing the full-scale SVE system using the ICE technology, bioventing and SVE with thermal oxidation were evaluated and determined not to be cost effective technologies for this site. In 1994 Parsons Engineering Science, Inc. (Parsons ES), under contract with the Air Force Center for Environmental Excellence (AFCEE), conducted an SVE pilot test to collect cost and performance data on the ICE technology and to provide recommendations for the full-scale SVE system design. A full-scale SVE system using two 460-cubic-inch engines is now operating at a total volatile organic compound (VOC) removal rate of approximately 2,200 pounds per day, with a destruction efficiency exceeding 99.9 percent.
