This report assesses the application of cross-borehole ERT at a pilot scale test site undergoing remediation by injection of reactive reagents to remove chlorinated ethenes. The pilot scale test site, the design, result and recommendation with respect to the remediation are reported in Region Hovedstaden (2023). This report describes the use of cross-borehole DCIP (direct current – induced polarization) for monitoring the injection pilot scale remediation at Hvedemarken. The report describes three aspects: • Monitoring the injection by use of DCIP data • Determination of hydraulic conductivity (K) from DCIP data • Quantification of Contaminant Mass Discharge (CMD) The main focus will be on the monitoring of the remediation reagents which was the original focus of the project. A scientific paper describing in more details the methods and results is published in Water Resources Research [Lévy et al.20022]. A second paper focusing on hydraulic conductivity and contaminant mass discharge is currently under revision [Thalund-Hansen et al., 2023]. A note describing the application of the contaminant mass discharge at the site is included as an appendix in Region Hovedstaden (2023). Finally, a paper describing the biogeochemical processes and potential relationship to DCIP is under preparation [Thalund-Hansen et al., in prep].
