Introduction. One of the most important tasks to ensure the sanitary and epidemiological well-being of the population of the Vladimir region is to provide it with high-quality drinking water. Due to the territory of the region to be partially associated with known hydrogeochemical anomalies of excess manganese content in groundwater, a hygienic assessment of the water of economic and drinking sources was carried out according to the content of this element.

Materials and methods. The paper presents the data of own research of the Department of Biology and Ecology of the Vladimir State University named after A.G. and N.G. Stoletov for 2021. During this period, the authors of the work examined about 110 samples of water from the household and drinking centralized and non-centralized water supply of the Vladimir region. Water samples were taken in the largest settlements (these are district centers, regional cities and large district settlements) and from drinking water sources of individual farms located in the territory of the region in various districts. The manganese content in water was determined on the analyzer “Fluorat-02-5M” according to HDPE F 14.1:2:4.188-02.

Results. The drinking water of the centralized water supply of the Vladimir region in terms of manganese content was established to meet regulatory requirements and be safe for the health of the resident population. In all samples of drinking water, the concentration of manganese is below 0.1 mg/dm3. At the same time, water from underground sources of non-centralized water supply has in some cases an excess of manganese (from 2 to 7 MPC), which is primarily due to the specifics of the geochemical composition of the water-bearing rocks of these territories.

Conclusion in order to provide the population of territories using underground water with a high content of manganese, it is necessary to build local modular water treatment plants using modern methods of non-reactive de-ironing and demanganation and using effective modern equipment and filtering materials.
