Abstract
The paper studies the results of social and hygienic monitoring of drinking water from centralized water supply systems carried out in the Primorsky Krai, in comparison with Russian indicators according to state reports. Attention is paid to the state of sanitary protection zones, a comparative characteristic of underground and surface sources of drinking water is given in terms of sanitary and epidemiological well-being. There is a decrease in the proportion of samples in the Primorsky Krai that are unsatisfactory in sanitary and epidemiological terms, due to the elimination of water sources that do not have sanitary protection zones along the region. In terms of sanitary and chemical indicators, the proportion of detected unsatisfactory samples taken from underground sources is higher than that of samples taken from surface sources. There is a lag in the provision of high-quality drinking water to the rural population compared to the urban population, and this gap is predicted to increase due to migration outflow to the urban environment and the postponement of the reconstruction of water supply systems. The leading role of surface sources in providing water supply to the largest number of the population of Primorsky Krai, the laboriousness of water treatment and transportation of water against the background of a reduction in the number of sources and centralization of water supply around more productive water sources are noted. The frequency of non-standard samples of drinking water in terms of microbiological indicators is included in the list of primary factors affecting the sanitary and epidemiological well-being of the region. In the Primorsky Krai, hydrogeochemical provinces were identified according to the increased content of manganese in the water and the physiological inferiority of drinking water. The importance of assessing the quality of drinking water, which has a significant impact on the formation of public health, is emphasized.
