HYDROGEOCHEMICAL STUDIES AND ZONING GROUNDWATER OF QUATERNARY DEPOSITS (ON THE EXAMPLE, THE TASHKENT REGION)

Abstract

The underground waters of the Pritashkent Artesian basin differ in different hydrogeochemical situation. On the one hand, the rapid development of resorts, sanatoriums, health resorts, as well as bottling since the early 50 s has led to a decrease and change in the chemical composition of the upper Cretaceous aquifers, and on the other hand, natural waters suitable for drinking
water supply are widely distributed in the upper part of the section, which are constantly subject to man-made processes.This situation has led to a change in the chemical composition of groundwater. The study of the processes of formation of the chemical composition of groundwater and the peculiarities of their distribution in the plan and section of the studied
territory should be an important element of most types of hydrogeological studies -hydrogeological survey, exploration of fresh groundwater deposits and their organization of a monitoring network.
