Аннотация Pollution of water bodies—sources of drinking water supply, an important factor negatively affecting the health of the population. It is known, that in the settlements of the Murmansk region there was no excess of sanitary hygienic standards for drinking water. The main task of the presented work was to consider the processes of formation of the chemical composition of groundwater in the Apatity–Kirovsk district within the water-rock system, to study the chemical forms of migration of elements, the chemical composition of the new formed phases. Complete hydrochemical analysis showed the presence of such elements as uranium, molybdenum, silver, barium, nickel, vanadium, aluminum and lead in the waters. These data have added to the database of groundwater chemistry. It was found that in the studied water sources such elements as calcium, sodium, potassium, magnesium, sulfate ion, necessary for human life, are in a chemical form useful for human health (Ca2+, Na+, K+, Mg2+, sulfate ion SO42−). Forms of migration of carcinogenic or toxic elements (nickel, barium, vanadium, strontium, aluminum and lead)—are present in the most toxic chemical form Ni2+, Ba2+, HVO42−, Sr2+. The ability to replace calcium in the bones is one of the most severe consequences of the action of inorganic compounds of lead, barium, strontium. It is known that free ions Ni2+ are more toxic than its complex compounds with inorganic and organic ligands. In the structure of the General morbidity of the adult population of the Murmansk region, the largest share falls on diseases of the circulatory system (17.9%) (Apatity city), in second place—the musculoskeletal system (13.2%) (Apatity and Kirovsk). In addition, there is a significant excess of the average Russian morbidity rates for tumors and anemia. The data obtained explained and supplemented the already known facts of morbidity of the population of the Apatity–Kirovsk district.
