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

Enhanced reductive dechlorination has successfully been applied in high permeability media contaminated with chlorinated ethenes, but has not yet proved its effectiveness for use in low permeability media. In Denmark there are only few examples of such “in-situ” bioremediation, focusing on the source zone located in clay till and so there is a need for a better understanding of the different processes implied in this remediation technology.

In this project a numerical model of chlorinated ethenes transport and degradation in fractured clay till is developed. The model aims at a better characterization of the processes controlling contaminant transport and fate and assessment of treatment effect and time frame.

The project is financed by Region Hovedstaden and Miljøstyrelsens Teknologiprogram for jord- og grundvandsforurening.

Miljøstyrelsen has set a management group in order to conduct the work. The group consists in:

Carsten Bagge, Region Hovedstaden
Henriette Kerrn-Jespersen, Region Hovedstaden
Jesper Elkær, Region Hovedstaden, now in København Energi
John Flyvbjerg, Region Hovedstaden
Ole Killerich, Miljøstyrelsen
Henrik Jannerup, Region Sjælland
Mette Christophersen, Region Syddanmark
Henrik Rud Larsen, Region Midtjylland

The report is divided into a main report and a separate report with appendices
