متن کاملEffects of source zone heterogeneity on surfactant-enhanced NAPL dissolution and resulting remediation end-points.
The effectiveness of removal of nonaqueous phase liquids (NAPLs) from the entrapment source zone of the subsurface has been limited by soil heterogeneity and the inability to locate all entrapped sources. The goal of this study was to demonstrate the uncertainty of degree of source removal associated with aquifer heterogeneity. In this demonstration, source zone NAPL removal using surfactant-en...
متن کاملDense nonaqueous phase liquid (DNAPL) source zone characterization: Influence of hydraulic property correlation on predictions of DNAPL infiltration and entrapment
[1] The influence of aquifer property correlation on multiphase fluid migration and entrapment was explored through the use of correlated and uncorrelated porosity, permeability, and capillary pressure-saturation (Pc-Sat) parameter fields in a crosssectional numerical multiphase flow model. Data collected from core samples in a nonuniform sandy aquifer were used to generate three-dimensional aq...
متن کاملRemediation of a Fractured Rock Aquifer Containing Trichloroethylene Dense Nonaqueous Phase Liquid
Extensive chlorinated solvent contamination, including trichloroethylene (TCE) dense nonaqueous phase liquid (DNAPL), was found in ground water at a Navy Installation Restoration Program site on a former Navy property in Pennsylvania. Ground water at the site is encountered in the Triassic age Stockton Formation, which consists of gently dipping, alternating sandstone and mudstone units. Ground...
متن کاملStochastic Analysis of Dense Nonaqueous Phase Liquid Dissolution in Naturally Heterogeneous Subsurface Systems
Field-scale Dense Nonaqueous Phase Liquid (DNAPL) dissolution in three-dimensional heterogeneous subsurface systems is investigated using a stochastic approach that treats the variability of flow properties as three-dimensional random fields. A steady-state, quasi-static DNAPL saturation distribution in a source zone is derived, based on the previous research to describe the field-scale nonunif...
