ABSTRACT
This paper presents an analysis of groundwater from the intakes “Park” and “Motława” situated in Tczew (Poland). These water intakes have varied hydrological conditions and volume of utilized resources (wells). In this area, the deepest drillings extend to 180 m (cretaceous stage) with 20% being constituted by tertiary-quaternary formations with depths ranging from 60 to 63.7 m. The distribution of water from the intakes depended on the population to which it was supplied and the average production of water ranged from 5,802.4 to 7,591.5 m3 per day on “Motława” intake and from 3,196.3 to 4,125.4 m3/day on “Park” intake and did not exceed the production capacity specified by the regulations. In 1994–2009, analyses of water intended for consumption from the above-mentioned intakes in Tczew were performed by testing the water reaction and the content of ammonium ions and chlorides. In the period of the studies, the permissible reaction was not exceeded and the concentrations of ammonium ion and chlorides were on a relatively steady level.
