Results of quality studies of spring waters of the Republic of Tatarstan

Abstract

The study of springs is of great scientific and practical interest, because the population increasingly prefers to use spring water as an alternative source of drinking water. Methods. Studies were conducted to determine the water quality in 14 springs located on the territory of the Republic of Tatarstan, according to physical and chemical indicators in the summer period by organoleptic, potentiometric, titrimetric, photometric and gravimetric methods. Results. It was found that the water fully meets the hygienic requirements in only 8 springs (57.1 %). It was revealed that the non-compliance of spring waters with sanitary standards for physical and chemical parameters is associated with the excess of the MAC for nitrates and hardness. Also the excess of the MAC for total alkalinity was determined. The main reasons for the poor quality of drinking water are the pollution of water sources. The data obtained confirmed the need for constant monitoring of the water quality in all springs and development of measures to improve them.
