Part I: Bioventing Pilot Test Work Plan for Former Fire Training Area (FT-13) Kirtland AFB, New Mexico. Part II: Draft Interim Pilot Test Results Report for Former Fire Training Area (FT-13) Kirtland AFB, New Mexico

摘要

This work plan presents the scope of an in situ bioventing pilot test for treatment of fuel-contaminated soils at the former fire training area at Kirtland Air Force Base (AFB), New Mexico. The pilot test has three primary objectives: (1) to assess the potential for supplying oxygen throughout the contaminated soil interval, (2) to determine the rate at which indigenous microorganisms will degrade fuel when stimulated by oxygen-rich soil gas, and (3) to evaluate the potential for sustaining these rates of biodegradation until fuel contamination is remediated to concentrations below regulatory standards. The pilot test will be conducted in two phases. A vent well (VW) and monitoring points (MPs) will be installed during site investigation activities. The initial stage will also include an in situ respiration test and an air permeability test. This initial testing is expected to take approximately 2 weeks. During the second phase, a pilot bioventing system will be installed and monitored over a 1-year period.
