The consequence of continuous environmental pollution is deteriorating of the quality of surface water. Raw water is being modified to drinking water by technological processes, and it is therefore necessary to put increased demands on the efficiency of these technological processes and their possible innovation. Drinking water treatment is still unable to treat the raw water perfectly, its pollution is only reduced to acceptable standards. For this reason, it is indispensable that the quality of drinking water is being checked regularly and at the same time the efficiency of individual technological processes of drinking water treatment is assessed. This includes screening analysis or eventually ecotoxicological tests. Experimental part was focused on the evaluation of the efficiency of technological processes of drinking water treatment. Samples of raw water and samples of water after each treatment stage were collected at the drinking water treatment plant in the Czech Republic. These samples were subjected to ecotoxicological tests and screening analysis. Based on the ecotoxicological tests carried out on Thamnocephalus platyurus, Lemna minor and Vibrio fischeri, we can assume the emergence of harmful chlorinated by-products, which resulted to nearly 100% mortality of T. platyurus. Screening analyzes were performed after the extraction of specimens by the SPE method using HPLC/MS. The results of the screening analysis indicate, that the most effective method for the removal of hormonal substances is ozonization.
