Artificial recharge is a method to increase the capacity to extract groundwater by augmenting the natural infiltration of surface water. At the same time the top soil is utilized as a reactor for treatment of surface water. A wide spectrum of research challenges need to be addressed to fully benefit from the technique. In the project IMT focuses on physical, chemical and biological processes occurring during clogging of laboratory columns simulating the sand bed of artificial recharge basins. Methods for characterization of the water input and the clogging materials (particles, algae and biomass) found in artificial recharge systems are tested. Furthermore, experiments are conducted to measure the development of redox zones during progress of biological growth and clogging. The project is part of the European research project Artificial recharge of groundwater (1996-98) which is funded partly by the European Committee through the 4th framework programme Environment and Climate. This project involves nine different Europen partners and includes six work packages, (1) clogging and heterogeneity, (2) organic compounds and biodegradation, (3) redox dynamics, (4) water-aquifer material interaction, (5) fate of pathogens and (6) integration of knowledge from all work packages
