Based on the monitoring of the water area of the Klyazma reservoir, it was revealed that in terms of such indicators as mineralization, BOD, COD, anionic synthetic surfactants, dissolved oxygen, pH, the water pollution index was 1.77-6.15. Water can be classified as moderately polluted, polluted, dirty and very dirty waters. A lower self-cleaning ability of water in the summer-spring compared to the autumn-winter period was revealed. The potential of self-protective ability varied within 1.16-11.17. According to the results of biotesting, the studied samples are characterized as non-toxic.
