Abstract

ESTIMATION OF WATER QUALITY AND SUSCEPTIBILITY OF THE FIRST AQUIFER TO POLLUTION IN THE BRZEGI–PIŃCZÓW SECTION OF THE NIDA RIVER VALLEYAbstract. This article presents estimation of water quality and susceptibility of shallow water table aquifer to pollution in the Brzegi–Pińczów section of the Nida River valley. Groundwater vulnerability is evaluated according to mean residence time (MRT) determined by the time of water infiltration from the ground surface to the groundwater table of the first aquifer according to the piston flow model of soil water and unsaturated zone water. The analysis shows that the groundwater vulnerability is mainly very high and high in the study area. This means that the aquifer is susceptible to penetration of pollution from the surface. On account of the risk of nitrogen contamination to the first aquifer waters, it is necessary to monitor nitrogen content changes in groundwater.
