Use of surrogate compounds to monitor DAPL removal from a contaminated soil during a cosolvent flood
- Clemson Univ., SC (United States)
Several constituents of a light nonaqueous liquid (NAPL) are selected as potential surrogates for NAPL removed from contaminated soil during a cosolvent flood. These surrogates are chosen on the basis of their representativeness of the free-phase NAPL in terms of hydrophobicity and volatility. The relative abundances of these compounds in separate samples of free-phase NAPL are compared to the ratios of those compounds in the contaminated soil to determine an appropriate set of surrogates for monitoring the cleanup of the soil. An extraction method is tested to determine the limits of accuracy for assessing cleanup of a soil. Cosolvent floods are performed and surrogate-based estimates of NAPL removal are compared to measurements of NAPL sturation prior to and subsequent to the cosolvent flood as determined by extraction and analysis.
