(2020) Shevchyk, K.; Maksymov, O.; Sheremet, K.
Determination of the quality of drinking spring water of the Kharkiv city to establish the level of safety for human consumption. Research. In the laboratory, the main characteristics of water quality from four urban drinking water sources were determined, and the dynamics were determined in connection with the changes of the seasons. The results were obtained. It is established that with change of season the chemical composition of spring water changes. In particular, in all spring water samples, pH, alkalinity, turbidity, total mineralization, and nitrate and nitrite content increased. Hardness exceeding the limit values in summer water samples decreased in autumn samples: 4.1 times in the water from the Hlibokiy Yar spring, 3.1 times in the spring water in Sarzhyn Yar, and in the spring water in the “Yunost” park with 4.2 times. In the Zhukovsky spring the water hardness has remained the same - 10 mmol / dm3.
