EVALUATION OF EFFICIENCY OF WATER TREATMENT SYSTEMS AND THEIR MODERNIZATION. QUALITATIVE AND QUANTITATIVE INDICATORS

Ensuring the sustainable development of human society is impossible without a stable state of the natural environment. Water is a necessary part of the environment of existence, and has a significant impact on human health. This is especially true of the part that is a drinking water supply. In recent years, there has been a decline in the quality of water in surface water supply sources, which increases the problem of clean drinking water. In this paper, the main issues of the impact of an effective assessment on the quality of water consumed by people  are examined. Actual issues considered in this article are the environmental problems of the North Kazakhstan region. Examples are given and methods of assessment, as well as methods for conducting statistical studies on water quality assessment. To date, the work is relevant and covers various areas of science.
