The article deals with statistical processing of monitoring data for the content of trihalomethanes in drinking water of one of the infiltration Ufa water intakes. Using the methods of mathematical statistics, the following parameters were revealed: the distribution density of the total content of trihalomethanes in drinking water, the likelihood of occurrence of adverse events associated with the formation of trihalomethanes as a result of the chlorination of drinking water. As a result of the analysis, it was found that the most common concentrations of the total content of trihalomethanes lie in the range 5.8-8.1 μg / dm3 . It was found that the distribution density of the total concentration of trihalomethanes is described by the power dependence ρ (TGM) = 0.348 × Q-2.18 (confidence level R2 = 0.94). It was concluded that the situation at the selected infiltration water intake can be considered favorable, since with a probability of 99%, the total concentration of THM does not exceed 18.03 μg / dm3 with an available maximum concentration of 100 μg / dm3.
