| Abstract: | This is the fourth in a series of papers through which the authors demonstrate how numerical transport modeling can assist the remediation design engineer in predicting the progress of enhanced reductive dechlorination remediation expected in the field. The first two papers dealt with the hydraulics of delivery and preliminary understanding of substrate‐limited degradation. The third paper compared a simulated substrate‐limited degradation progress to some early results measured at a site. Based on that comparison, conclusions were drawn regarding the differences in degradation rates between a field situation and laboratory studies, and inferences were made about the modeling steps needed to aid in designing enhanced reductive dechlorination systems. Since the presentation of those results, additional rounds of data have been obtained from the field, encompassing a more substantial range of degradation history. In this paper, the authors compare those results with the simulated predictions and present an illustrative example of design modification using the model. ©2016 Wiley Periodicals, Inc. |
