Natural-technogenic hydrogeochemical anomalies in groundwaters of the Southwestern Moscow Artesian basin

Pollution of potable water with natural elements is an important issue for many towns of central Russia. Study of the chemical composition and hydrodynamics of groundwaters made it possible to establish some regularity in the influence of the anthropogenic load and exploitation regime of water intake (hereafter, intake) on their quality. It is shown that the quantitative prognosis of pollution of water wells should be based on the complex study of geochemical, hydrodynamic, and economic conditions of water consumption. Solution of the problem concerning the quality of groundwater within natural-technogenic hydrogeochemical anomalies requires an integrated strategy of measures aimed at adaptation of the water consumption to limits of natural stability in the water basin and to reduction of the emission of technogenic toxic substances and greenhouse gases. It is recommended to carry out complex geochemical studies of the aquifer in order to predict the possible groundwater pollution by natural pollutants. The study is based on the results of analysis of 5000 samples carried out at the Chemical-Analytical Center of the Taifun Scientific-Industrial Enterprise of the Russian Hydrometeorological Center and the Vodokanal Small Enterprise (Obninsk).
