Remediation 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 کاملA functional relation for field-scale nonaqueous phase liquid dissolution developed using a pore network model.
A pore network model with cubic chambers and rectangular tubes was used to estimate the nonaqueous phase liquid (NAPL) dissolution rate coefficient, Kdissai, and NAPL/water total specific interfacial area, ai. Kdissai was computed as a function of modified Peclet number (Pe') for various NAPL saturations (SN) and ai during drainage and imbibition and during dissolution without displacement. The...
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...
متن کاملDense Nonaqueous Phase Liquid Migration in a Complex Multi-aquifer System
A laboratory experiment was conducted to demonstrate the behavior of dense nonaqueous phase liquid (DNAPL) 1,1,1-trichloroethane (TCA) in a complex aquifer system. The system simulated consists of two unconfined aquifers separated by a low permeable bedrock perching layer that contains a fracture. In contrast to previous work by other researchers of DNAPL migration in hydrostatic conditions, in...
