The “Kljuc” groundwater source in the alluvion of the Velika Morava River provides water supply for the City of Pozarevac at a rate of roughly 220 l/s. Groundwater is abstracted by means of tube wells which are up to 20 m deep. Since 2000, nitrate concentrations in water at this source had a continuous upward trend. Constant intrusion of groundwater with nitrate concentrations higher than 100 mg/l, mainly from suburbs which have no access to utility services, led to a temporary shutdown of the source in 2006. However, following the construction and commissioning of an infiltration-based protection system, a hydraulic barrier was created which allowed the water source to continue to service the public water supply system. This paper presents the performance of this system during the period from September 2006 to March 2007.
