ABSTRACT
The transfluent drinking water reservoir Goczałkowice has served as a model basin for several different studies that have permitted an estimation and prognosis of the shortterm and long-term changes that have occurred in it. This work presents studies using the physical-chemical spectroscopic methods to investigate bottom sediments that were taken within a period of one year in the spring, summer and autumn, and at particular points of water intakes. Winter sampling was not possible since the reservoir was covered with a layer of ice, which prevented a boat from being launched. The identification of elements that were included in the material was done using the X-Ray photoelectron spectroscopy and the X-ray diffraction measurements to determine the chemical compounds, while the magnetic properties of the samples were examined using a Superconducting Quantum Interference Device magnetometer. Moreover, the activity of radioactive elements was determined using nuclear spectrometry techniques. Finally, the Scanning Electron Microscopy was used for microstructural observations and a microcompositional analysis of the studied samples. The experimental data that was obtained permitted a global description of the bottom sediments of the water reservoir depending on the season of the year during which the intake was performed or the place from which the samples were collected. The investigations were very important since this transfluent reservoir in Goczałkowice serves as the drinking water basin for the post-mining area populated by 3.4 million inhabitants.
