Abstract

Summary

An objective assessment of the current hydrochemical state of water bodies is complicated by the limited number of regular studies of chemical ingredients. The chemical composition of water should correspond to the natural state of water bodies and ensure the normal functioning of a typical ecosystem. The reliability of the conclusion on the hydrochemical state of water bodies should not be lower than 99%, as environmental protection measures require significant material costs. The parametric Wald theory was used to determine the water status classes. This theory guarantees high reliability of the assessment and is adapted to short series of observations. Based on Wald’s theory, an approach to estimating the confidence interval of the trend in the concentration of chemical indicators was developed.
