Need to Сonsider Sulfates Transformation in Surface Water Under Environmental Control

Abstract

The problem of quality and safety of surface fresh water is considered. The global character of its sulfate contamination is shown. Critical analysis of hydrochemical parameters of surface water is carried out on the example of the negative impact of an object polluting a watercourse with sulphate run-off. The preconditions for the violation of the hydrochemical regime and the danger of the occurrence of the sulfate type of water of the calcium group are revealed on the basis of quantitative relationships of the main ions. The high probability of formation of toxic properties of the aquatic environment due to the unaccounted-for sulfate reduction process with the formation of hydrogen sulphide is discussed, which is a factor of ecological risk. The need to develop a methodological basis for state regulation in the field of rationing of pollutants in surface water, taking into account their chemical transformation, is shown.
