ABSTRACT
The concept of improveming artificial groundwater recharge by different (activated carbons and anthracite coal) in-site reactive barrier-systems has been researched. Micropollutants (e.g. pesticides) were significantly reduced by the systems. Operation time depends on the micropore structure and sorption kinetics of the activated carbons (sorption reactor). No distinct improvement of pesticide removal was observed by Anthracite (biological reactor).
