Intrinsic Bioattenuation of JP-4 Jet Fuel Constituents in Groundwater at March Air Force Base Operable Unit 3
Abstract
This report describes efforts to determine whether or not intrinsic bioattenuation occurs at significant rates and extents in the shallow aquifer at Operable Unit 3 at March Air Force Base (AFB), California. The aquifer is contaminated with benzene, toluene, ethylbenzene and xylenes (BTEX) resulting from releases of JP-4 jet fuel from an aircraft refueling system. Efforts focused on use of existing quarterly groundwater monitoring data and data from a Comprehensive Environmental Response, Compensation and Liability Act Remedial Investigation performed from 1991 through 1994. A technical protocol published by the Air Force Center for Environmental Excellence to determine the rate and extent of intrinsic bioattenuation was followed where applicable data exist. Three hypotheses were tested in a phased approach: (1) Intrinsic bioattenuation occurs in groundwater at March AFB Operable Unit (OU) 3 (2) Intrinsic bioattenuation occurs in groundwater at OU 3 at rates and extents such that receptors will not be affected (3) Intrinsic bioattenuation occurs at rates and extents such that the aquifer will eventually be restored to background water quality.
