Numerical Modeling of Experimental DNAPL Release at Dover AFB
Abstract
This research investigated how numerical modeling of dense nonaqueous liquid phase (DNAPL) spills can assist in the planning of field experiments of controlled DNAPL releases. The procedure was first validated using existing data from a controlled release at the Borden test site, and then extended to hypothetical releases at the Dover site. The simulation results confirmed that the total release volume, the infiltration rate and the DNAPL injection head are important parameters for the design of controlled release experiments. Specifically, it was found that proper selection of the injection head and the release volume through several numerical simulations can aid in controlling the extent of the DNAPL-contaminated area in the field. Finally, it was shown that considerable savings in computational time can be achieved by approximating the 3-D geometry with radial symmetric 2-D simulations. This is true provided that the soil distribution is relatively homogeneous at the horizontal plane, as it is the case at both Borden and Dover.
