Abstract

Significant advances have produced source zone remediation modeling tools of real practical value. These advances include improved understanding of the physics and biogeochemistry of DNAPL source zones, more rigorous mathematical descriptions of the relationships between multiphase flow, groundwater flow, contaminant transport, mass transfer and species reactions, and superior numerical algorithms and computing power. Models are available for a wide range of activities supporting site investigation and remediation, including testing of site conceptual models, choosing between remediation alternatives, designing and optimizing a remedial design, and examining the sensitivity of predicted outcomes to data uncertainties or engineering decisions. This chapter presents an overview of source zone remediation modeling. The relative advantages of analytical and numerical models are introduced. The main model components are presented, providing insight into the relationships between site data, simulated processes and modeling results. The key steps in carrying out a modeling study are discussed and several examples are presented to illustrate how source zone remediation models can be applied.
