Remediation of TCE source zone in Skuldelev by the ZVI-Clay technology

Source zones of DNAPLs can be complicated and difficult to delineate precisely. ZVI-Clay is a technology which contain the source by soil mixing bentonite and zero valent iron (ZVI) into the source zone area. The bentonite gives an immediate flux reduction from the source while the ZVI leads to degradation of the contained TCE. The technology has never been used outside USA. This project will closely follow the degradation processes within the treated source zone and the remedial effect on the TCE flux awy from the source.
