CHEMICAL COMPOSITION OF UNDERGROUND WATER SOURCES OF NON-CENTRALIZED WATER SUPPLY IN THE TOMSK REGION OF THE TOMSK OBLAST AND ITS POSSIBLE IMPACT ON HUMAN HEALTH

Abstract

: The results of studying the chemical composition of groundwater in non-centralized water supply sources in the Tomsk region of the Tomsk oblast are presented. High concentrations of the following components were found: hardness of water, Na + , K + , SO 4 2- , Cl - , NO 3 - , Fe, Mn, etc. For NO 3 - , Fe and Mn there is a multiple excess of not only background values for this territory but also MPC for drinking water. A review of possible cases of the influence of excess contents of the components of the chemical composition of water on the human body and related diseases is pre-sented.
