Improved Filed Evaluation of NAPL Dissolution and Source Longevity

Abstract

At former Williams Air Force Base, the Air Force conducted a pilot test of thermally enhanced extraction (TEE) to reduce the mass and longevity of a multi-component NAPL fuel source in the saturated zone. Before and after the pilot test, novel tools were applied in the source zone to measure and analyze mass discharge. The tools included integral pumping tests combined with deployment of Passive Flux MetersTM and mutli-component modeling using the source zone depletion function of the model SEAM3D. Resulting data were synthesized into a model of NAPL architecture and mass dissolution. The change in the mass discharge rate pre- and post-TEE was compared to the mass removed from the subsurface during the TEE pilot test as a criterion for the success of the demonstration. Generalized results from the mass transfer testing at ST012 can be used at other sites to improve characterization approaches for NAPL source areas.
