Abstract. Researchers from Russia and foreign countries, studying medical and environmental contamination of drinking water, point to the relationship of public health with chemical composition of groundwater and anthropogenic inclusions. The aim of the work is to detect the change in chemical composition of natural waters formed within the Khibiny massif and its closest framing depending on the composition of rocks in the catchment area and on anthropogenic impact by means of physical and chemical modeling and modern precision methods of 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 of such elements as uranium, molybdenum, silver, barium, which supplemented the database of groundwater chemical composition. For the physical-chemical modeling, there have been made some samples of chemical analyzes of the most common rocks composing the southeastern part of the Khibiny massif as the main catchment area. The analysis of the obtained results has made it possible to separate the rock influence from anthropogenic, natural chemical composition of waters from filtered mined (anthropogenic). It has been shown that already in natural (pure) waters the ratios of Ca/P and Ca/Sr can lead to bone diseases. It has been determined that the chemical composition of groundwater from the "Predgorny" water intake is affected by the chemical composition of rocks and surface waters containing oxygen, nitrogen nitrates, chlorine, which affect pH (reducing it), the migration patterns of aluminum, manganese, iron and other elements. In the bones of humans and animals, approximately 70 % falls on hydroxyl apatite Ca5(PO4)3OH. OH group can be replaced by F, Cl, O. Calcium can be isomorphically replaced by a number of elements: Sr, U, Ba, etc. that lead to diseases of bones and teeth. The research results can be useful in the fields of geochemistry, hydrology, ecology, and medicine
