Abstrakt		It has been observed that the artificial lake water from the Solkan hydroelectric power plant mixes with the water from the natural spring Mrzlek. This mixing could bring pollutants from the river/lake into the pumped water of the Mrzlek Waterworks. The waterworks supply drinking water to more than 30,000 inhabitants. In order to evaluate the mixing, water and sediments from the artificial lake, the raw and conditioned water from the Mrzlek Waterworks had been analysed periodically from 1985 to 2005. The concentrations of some heavy metals, mineral oils, organic substances (particularly the THM's, which are formed during the chlorination process) had been measured by samples. The genotoxicity of drinking water has been analysed in connection with the presence of THM's. The incidence of seven different studied types of malignant neoplasms with the exposed and reference populations (population drinking water from the Mrzlek Waterworks and population not drinking water from the Mrzlek Waterworks) had been analysed. On the basis of chemical analyses of some heavy metals and organic substances and their comparison with the measurements from the previous years, it may be concluded that accumulation of hazardous substances in sediments is slight. The constant presence of halogenated hydrocarbons in drinking (conditioned) water has also been observed. The study conducted on the mutagenic potential of drinking water from the Mrzlek Waterworks showed genotoxic effects on the test micro organisms and cells. Regardless the results of genotoxicity tests, the standardised incidence ratios of the studied malignant neoplasms in the exposed and non-exposed population and their comparison did not show a substantial difference.
