Tracer Techniques for DNAPL Source Delineation and In-Situ Flushing Techniques for Enhanced Source Removal: Pilot Scale Demonstrations at the Dover National Test Site
Abstract
The objective of this study was to evaluate the performance of innovative tracer techniques for dense nonaqueous phase liquid (DNAPL) characterization and in-situ cosolvent and surfactant flushing for DNAPL removal in an isolated test cell (3.0m x 4.5m x 1 2.3m) located at the Dover National Test Site, Dover AFB, DE. As part of a larger project to assess the performance of several in-situ flushing technologies for DNAPL source removal, it involved controlled releases of up to 100L of perchloroethylene (POE) into test cells for each remedial technology. Subsequent to POE release, two partitioning tracer tests were conducted: one before and another after the remedial test. The University of Florida (UF) conducted the first remedial demonstration, cosolvent flushing, and the second remedial demonstration, surfactant flushing, was conducted jointly by UF and the University of Oklahoma (UO). The focus of this report is the four partitioning tracer tests and the cosolvent flushing demonstration.
