Quality indicators of water supplied to consumers "Drinking water”. Hygienic requirements and quality control" are set according to the state standard AZS 929:2023. The new standard, approved in April 2023, was developed based on the Water and Health Protocol of the UN Convention on the “Protection and Use of Trans boundary Watercourses and International Lakes”. This standard is designed with the recommendations of the working document presented by the European office of the World Health Organization, Directive 2020/2184 of the European Parliament and of the Council of Europe of 16 December 2020 on the quality of water intended for human consumption, ГОСТ 2874-82, СанПин 2.1.4.1074- 02, USEPA standards in mind.
