Abstract:

This document describes the results of a field test, which assessed the applicability and feasibility of promoting the in-situ bioremedition of chlorinated solvent compounds PCE, TCE, etc. by using a mulch biowall and surface amendment near Building 301 B301, Offutt Air Force Base, Nebraska. The biowall was installed in the vicinity of MW-9 where the water table is high i.e., 6 ft bgs and was filled with mulch produced at the Base. The conceptual model for this technology is that the native organic matter fermented, producing hydrogen to stimulate reductive dechlorination. Similarly, a natural organic matter amendment was applied to the ground above the plume in the vicinity of MW-9. This treatment method relies on infiltration to transport soluble organic matter into the subsurface, where the organic matter can then ferment, producing hydrogen to stimulate reductive dechlorination.
