Abstract:
In this article, the purpose of the research was to study the ecological characteristics of groundwater and central
water supply used for drinking and economic activity of the Kievka village. The hydrochemical indicators of the
samples were determined with conventional methods, and performed on 16 indicators: pH, electrical conductivity, suspended solids, dry residue, chlorides, sulfates, phosphates, total hardness, sodium, ammonium nitrogen,
nitrites, nitrates, chemical oxygen consumption (COD), anionic surfactants (APAS), total iron, and manganese.
While assessing the hydrochemical state of drinking water in the village of Kievka, it can be noted the “Altyn-dan”
kindergarten and the Kiev secondary school No. 3, exceed the MAC which is determined by certain indicators. As
a result of microbiological studies of the water samples from the village of Kievka, it was revealed that the total
microbial number is normal. It was determined that a different number of fungi and actinomycites were present in
all samples. At the initial concentration, a large concentration of fungi was observed in all samples.
