Model assessment of reductive dechlorination as a remediation technology for contaminant sources in fractured clay

02-07-2009

A better understanding of reductive dechlorination as a remediation technology in fractured clay systems is achieved by development of a numerical model characterizing the main processes and assessing the clean up times. These can be significantly reduced when dechlorination is enhanced. However the remediation action can increase the contaminant flux to the aquifer by the formation of daughter products. The results are sensitive to porosity, sorption coefficient, net infiltration and fracture spacing.
