Bezpieczeństwo sanitarne wody w wodociągach publicznych

Although epidemics of cholera were last reported in the 19th century, the managers of public water supply systems have always been on alert for every possible epidemic hazards. These days, epidemic is likely to come from protozoa (Cryptosporidium parvum and Giardia lamblia) and bacteria responsible for acute gastrointestinal disorder. The study reported in the present paper involved analyses of tap water quality provided by the waterworks of choice. The results show that the sanitary safety demands made on public water supply will be met if the water intake is free from pollution hazards. In general, the sanitary safety of the public water supply system is determined by the following factors: the quality of the token-in water, the treatment train, the disinfection methods, and service conditions. For these reasons, the implementation of membrane techniques should be considered as future best available technology.
