Completion of One Year Bioventing Test, Buildings 1639 and 1812
Abstract
The Air Force Center for Environmental Excellence (AFCEE) one-year bioventing test and evaluation projects at Buildings 1639 and 1812 have been completed. For each site Figure I provides general site information and Table 1 provides a summary of initial, six-month, and one-year fuel respiration and degradation rates measured at several monitoring points. Overall, for Building 1639, biodegradation rates have decreased over the one-year pilot test These decreases are best explained by the reduction of contaminant levels as the bioventing continued. For Building 1812, the oxygen levels at monitoring point MPA seem to naturally remain elevated. it is possible that this monitoring point is in relatively uncontaminated soil and the vent well is in a relatively contaminated area. Table 2 provides a summary of initial and final soil and soil gas analytical results for total recoverable petroleum hydrocarbons (TRFH) and benzene. toluene, ethyl benzene, and xylenes (BTEX).
