In experimental conditions, an assessment was given on the efficiency of active chlorine effect on the viability of microorganisms having a sanitary-epidemiological significance. It was shown that in conditions of intensive water source contamination of maximum load using treatment facilities with double chlorination (chlorine dose 5 mg/l) after 30 minutes of contact, only E.coli died, at the same time, conditionally pathogenic and pathogenic microorganisms, the infective dose of which was within the same limits (50 000 CFU/l), were inactivated by 99,9 %; with an increase in the applied dose of 10 and 100 times, the degree of inactivation decreased in Salmonella to 99,5 %, in Pseudomonas aeruginosa to 99,2 %, Klebsiella remained at the same level of 99,9 %. This predetermines the possibility of their appearance in drinking water, which can lead to the emergence of acute intestinal infections among the population.
