State of the art methods for in-situ remediation of hydrocarbon contaminations comprise either the use of groundwater permeable reactive barriers or the infiltration of reactive solutes. Within KOPOXI, a pilot experiment of a newly developed combination of such a permeable reactive barrier and the injection of reactive solutes is performed at a hydrocarbon contaminated site.

One of the objectives of the department MET is the technical development of a sealing that impedes vertical flow along Direct Push monitoring and/or injection wells for depth discrete sampling or injection of reactive solutes. Moreover, MET will focus on the development, optimization and verification of an innovative monitoring strategy to observe and optimize the injection of reactive solutes. This includes the use of high-resolution hydraulic in-situ datasets to determine mass flow rates of contaminant loads resolved in both, space and time.
