Results of Additional Bioventing Respiration Testing at Sites ST61, ST71, and ST43/55 (Pumphouse III and Valve Pit 3-4)
Abstract
Initial bioventing pilot tests were completed by Parsons ES at four sites at Elmendorf AFB, Alaska during the period from June 15 through July 19, 1993 (ES, 1993). Vent well and monitoring point construction, respiration and air permeability testing, soil and soil gas sampling, and blower system installation and startup was performed at each site as part of the initial testing. To monitor remedial progress, 6-month and 1-year respiration testing was performed, and 1-year soil and soil gas sampling was completed. In September 1994, Parsons ES was awarded a task order from AFCEE (contract F41624-92-D-8036 Order 17) to complete remediation monitoring and design and/or closure sampling, and to implement full-scale bioventing at several US Air Force sites. The purpose of the new task order is to extend the operation of existing bioventing pilot systems, and to move forward with either site closure or design and implementation of full-scale bioventing systems. Four potential options were identified for each site.
