Dense 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 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...

متن کاملInvestigation into Dense Non-aqueous Phase Liquid (dnapl) Transport and Remediation in Vertical Fractures
This thesis investigates the transport behavior of a common category of industrial pollutants, known as Dense, Non-Aqueous Phase Liquids (DNAPLs). These organic chemicals are more dense than water and relatively insoluble. A typical release of DNAPL at the ground surface will migrate downward, relatively unhindered, until it reaches an impermeable clay layer or bedrock, where a pool begins to f...
