Carried out ecological and hygienic assessment of pollution of surface and groundwater of mining areas
in the Republic of Bashkortostan. Revealed exceeding standards for fishery water bodies and drinking
and cultural and community water use, which indicates the potential danger of surface water for the
health of the region's population. The greatest relative contribution to the overall pollution of surface
water bodies are making manganese (33,0–66,6 %), iron (9,1–15,6 %), calcium (6,5–11,7 %), lead (5,8–
7,2 %). The quality of water used for drinking purposes from decentralized water sources (boreholes,
wells, springs), do not always correspond to the hygienic and sanitary-epidemiological requirements. In
this case, the highest priority performance of drinking water contamination are increased stiffness, high
content of iron, calcium, nitrate, presence cadmium, and hexavalent chromium.
