Groundwater quality in the catchment area of the Świerczków infiltration groundwater intake in Tarnów
Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2009, Vol 436, Issue 436
Abstract
The Świerczków infiltration groundwater intake in Tarnów has been exploited since 1910. While building the intake, the surrounding area was undeveloped and free of potential industrial sources of groundwater contamination. At present, the Świerczków intake is surrounded by an industrial area of a large chemical company Zakłady Azotowe in Tarnów Mościce SA established in the 1920s. The infiltration wells extract water from the Pleistocene aquifer periodically additionally recharged by surface waters from the Dunajec River. Physiochemical parameters indicate significant changes in chemical composition of groundwater from the Pleistocene aquifer around the Świerczków water intake. Increased contents of Cl–, Na+, K+, NH4+, Al3+ and Cd2+ ions as well as the presence of multi-ion chemical types of most of the tested waters confirm the above theory. The wastes deposited in the area of Zakłady Azotowe and around, as well as pollution emitted by the factory are the main factors responsible for the quality and chemical state of the groundwater because of their direct and indirect permeation to water.
