Title: Field-scale evaluation of enhanced aquifer remediation using in-situ alcohol flushing

Abstract

In-situ flushing of soils and aquifers contaminated with a variety of fuels and oils (e.g., gasoline, diesel, jet fuels, solvents, degreasers, coal tar, creosote, etc.) is based on enhanced mobilization and/or solubilization of the entrapped residual oils. The former technique involves immiscible displacement of oil macroemulsions, ganglia, blobs, and banks, whereas the latter technique is based on enhanced solubilization of the oil constituents and their miscible displacement. Results from lab-scale and field-scale evaluations of in-situ flushing with water-alcohol mixtures for enhanced solubilization of residual oils will be discussed. Emphasis of the presentation will be on the data collected during a recently completed field test of the in-situ cosolvent flushing technology, which was conducted at the Hill Air Force Base, utah, to remediate a shallow, unconfined aquifer contaminated with jet fuel and chlorinated solvents. As a part of this field test, studies were also conducted to evaluate the use of partitioning tracers (methyl alcohols) for quantifying the residual oils present at the site prior to and after cosolvent flushing. Criteria for performance assessment as well as the technological, regulatory, and economic factors governing full-scale applications for aquifer remediation will be discussed.
