Abstract

The availability of high-quality drinking water is currently the one out of the most acute problems in the Russian Federation. There was performed an analysis of the chemical composition of drinking water from sources of decentralized supply of inhabitants of the city of Yekaterinburg and the surrounding areas. Average values of indices of the water quality in the wells for individual use in the district of the city of Yekaterinburg not go beyond the standards, with the exception of manganese content. In some sources there were revealed elevated values of chromatic level, oxidability, hardness, content of iron, nitrates, barium, dry residue, ammonium nitrogen, silicon. Percentage of sources that do not meet hygienic requirements on a number of indices can reach 21-23%.
