The purpose of the study was to monitor the quality of drinking water supply in Samara. The quality of drinking water was evaluated in 7 districts of Samara on the basis of 20 sanitary-chemical indicators in accordance with health and safety norms and regulations (SanPiN 2.1.4.107401 20102013 and 20182019). A changed color of drinking water was mainly observed in the areas with water supply from the Saratov reservoir (53,5 8,5% of samples). In the areas with underground water sources the dry residue and hardness of drinking water exceeded hygiene requirements by 100% and 87,5% of samples respectively. 64% of samples in 20102013 and 17,4% of samples in 20182019 were non-standard in terms of permanganate oxidation. Several samples didnt meet the hygienic standard for iron content. Adverse changes in the temporal dynamics of the proportion of samples that didnt meet the hygienic standard for the content of oil products were noted. The quality of some samples of drinking water in Samara did not meet sanitary requirements for some indicators. No significant differences were found between the average long-term values of sanitary and hygienic indicators for urban areas and the obtained data for drinking water in the new housing estate, which suggests that the condition of the water supply pipes doesnt influence the composition of the drinking water in the yard or at home.
