Bioventing bioremediation -- 1500 Area JP-4 jet fuel spill site, Kelly AFB, Texas
- Earth Technology Corp., Alexandria, VA (United States)
The 1500 Area at Kelly Air Force Base (AFB) was the site of a subsurface release of approximately 1,000 gallons of JP-4 jet fuel. Preliminary studies found evidence of hydrocarbon contamination extending from 10 feet below ground surface (bgs) down to the shallow water table, at 20 to 25 feet bgs. In June of 1993, Kelly AFB authorized the installation and evaluation of a bioventing system at this site to aid in the cleanup of the hydrocarbon contaminated soils. The purpose of the bioventing system is to aerate subsurface soils within and immediately surrounding the release area, in order to stimulate in-situ biological activity and enhance the natural bioremediation capacity of the soil. Augmenting oxygen to the indigenous soil microorganisms promotes the aerobic metabolism of fuel hydrocarbons in the soil. In vadose zone soils exhibiting relatively good permeability, bioventing has proven to be a highly cost effective remediation technology for treating fuel contaminated soils. In November, 1993, a Start-Up Test program consisting of an In-Situ Respiration Test (ISRT) and an Air Permeability Test was performed at the 1500 Area Spill Site.
