Ivanov The formation of the chemical composition of groundwater in South Prohibiny using the example of "Predgorny" water intake Researchers from Russia and foreign countries, studying medical and environmental contamination o f drinking water, point to the relationship o f public health with chemical composition o f groundwater and anthropogenic inclusions. The aim o f the work is to detect the change in chemical composition o f natural waters formed within the Khibiny massif and its closest framing depending on the composition o f rocks in the catchment area and on anthropogenic impact by means o f physical and chemical modeling and modem precision methods o f analysis. To achieve the goal the sampling has been taken at the "Predgorny" water intake (Koashva, the Kirovsk district). The complete hydrochemical analysis has shown the presence in waters o f such elements as uranium, molybdenum, silver, barium, which supplemented the database o f groundwater chemical composition. For the physical-chemical modeling, there have been made some samples o f chemical analyzes o f the most common rocks composing the southeastern part o f the Khibiny massif as the main catchment area. The analysis o f the obtained results has made it possible to separate the rock influence from anthropogenic, natural chemical composition o f waters from filtered mined (anthropogenic). It has been shown that already in natural (pure) waters the ratios o f Ca/P and Ca/Sr can lead to bone diseases. It has been determined that the chemical composition o f groundwater from the "Predgorny" water intake is affected by the chemical composition o f rocks and surface waters containing oxygen, nitrogen nitrates, chlorine, which affect pH (reducing it), the migration patterns o f aluminum, manganese, iron and other elements. In the bones o f humans and animals, approximately 70 % falls on hydroxyl apatite Ca 5 (P 0 4 ) 3 0H . OH group can be replaced by F, Cl, O. Calcium can be isomorphically replaced by a number o f elements: Sr, U, Ва, etc. that lead to diseases o f bones and teeth. The research results can be useful in the fields o f geochemistry, hydrology, ecology, and medicine.
