USING MULTI-ISOTOPIC APPROACH TO ASSESS THE EFFICACY OF INDUCED DENITRIFICATION IN AN ARTIFICIAL RECHARGE PILOT POND IN SANT VICENC DELS HORTS, CATALONIA

摘要

In the aquifers of the Llobregat River (Catalonia, NE Spain) overexploitation has led to decrease of groundwater level and seawater intrusion, with the consequent deterioration of the groundwater quality. In order to increase water availability and enhance water quality, different artificial aquifer recharge systems have been implemented along the main aquifer.
