A constant increase of nitrate ions (NO3-) concentrations (from ca. 10 to 400% in some wells within 1995-2005) is observed within the Major Groundwater Basin (MGWB) 326N exploited by the Water Supply and Sewerage Company in Czestochowa district. The verified fate and transport model allowed for determining concentrations and loads of NO3- introduced into groundwater within infiltrating precipitation, as well as scenarios of concentration changes until 2015 for diverse regimes of water extraction. From 6 considered scenarios, the most appropriate for the water intake Łobodno, is the extraction regime that will lead to the prognosed mean NO, concentration in 2015 of 44,0 mg/l (i.e. 91% of the concentration in 2005). In the case of the water intake Wierzchowisko, the most appropriate is the water extraction regime, for which the predicted mean NO, concentration is 59,3 mg/l (i.e. 102% of the concentration in 2005).
