PRECIPITATION POLLUTION EFFECT ON GROUNDWATER HYDROCHEMICAL REGIME

Pollution of precipitation is one of the main factors affecting the hy drochemical regime of groundwater. The main factors governing the conc entration of macro- and microelements, as well as the degree of acidif ication, have been evaluated on the basis of the long-term variability of the hydrochemical regime of groundwater. The results follow from t he generalization of the data obtained. Changes in the macro- and micr oelement concentration in groundwater have been studied, taking into a ccount the chemical composition of rainwater and snow meltwater.
