“…The values of the total hardness vary depending on the releases of the reservoir and the volumes of mineralized understream water entering the river [3]. Therefore, the total hardness of water can be considered as a random variable.…”

“…Long-term observations show that the water quality changes significantly, as a result of which a revision of previously obtained results is required [3]. This is especially true for the total hardness of water, since the values of the indicator have been increasing in recent years [3].…”

“…Groundwater is especially strongly dependent on the soils and rocks that make up the aquifers. Therefore, water from infiltration water intakes in Ufa is characterized by increased water hardness, since the main rocks are mainly limestones and dolomites [1][2][3][4][5][6][7][8].…”

Monitoring of the total water hardness in the river was carried out by means of mathematical modeling and statistical processing. The distribution laws of the total hardness are found separately for each month, which more accurately reflects the impact on the seasonality index. It is determined that the obtained empirical distribution functions of the indicator do not correspond to normal and log-normal distributions, but are quite accurately described by polynomials, which is confirmed by Kolmogorov’s goodness-of-fit criterion. The resulting distribution functions of the total hardness of water make it possible to predict the probabilities that the indicator will take certain values.

“…It is believed that drinking hard water is not harmful to human health [3,4], but there is evidence of negative health effects of both hard drinking water [3][4][5][6][7][8][9][10] and soft drinking water [11][12][13][14][15]. Therefore, water hardness is an important indicator of water quality for water use conditions [16][17][18][19].…”

The link between the total hardness of drinking water and the primary and total population turnover in polyclinics of the city, located on the territory supplied with drinking water from the infiltration water intake, for some diseases (malignant neoplasms, blood diseases, endocrine diseases, diseases of the circulatory system, respiratory diseases, digestive diseases, skin diseases, diseases of the musculoskeletal apparatus, diseases of the genitourinary system, congenital deformities) was searched. Different manifestations of links between diseases of the population and the available level of water hardness of the infiltration water intake zone were revealed.

The nature of the total water hardness distribution in the river has been studied. It was found that during the year, changes in the total hardness largely depend on the seasonal factor, therefore, an analysis of the indicator distribution separately for each month was also made. Empirical distribution functions of the total hardness were found from the built-in variational series. It was found that the obtained distribution laws of the water total hardness differ from the normal and lognormal distributions, but are described quite accurately by the gamma distribution. The put forward hypotheses about the laws of distributions were tested by Kolmogorov’s goodness-of-fit test and confirmed. The distribution functions of the water total hardness describe the probabilities of occurrence of events in which the indicator will exceed or not exceed the specified values.
