Quality monitoring of well waters of Zhydachiv district of Lviv region // Proc. of the State Nat. Hist. Mus. - Lviv, 2021. - 37. - P. 105-114
DOI: https://doi.org/10.36885/nzdpm.2021.37.105-114 Key words: Drinking water, ecological condition, total microbial count, coli-index, nitrites, nitrates, ammonium ions, phosphates, chlorides, mineralization, biotesting The article presents the results of the study for well water quality in Zhydachiv district on the following indicators: total microbial count, coli index, content of nitrites, nitrates, ammonium ions, phosphates and chlorides, mineralization and pH. Exceedance of regulatory values for the content of nitrates, chlorides and ammonium ions was established. Studies of the total microbial count in drinking water have shown that the average annual values correspond to the norm only in some settlements in the winter, and in some cases exceed 2.2-9.8 times. The same tendency for changes is inherent for the coli-index in the studied water, where exceedances of 2.3-6.9 times were observed. Seasonal biotesting of well waters was carried out. It was found that most of the tested samples do not meet the standard for sanitary and hygienic indicators. The phytotoxicity index varies from low (Vilkhivtsi, Zhyrova) to high (Zhydachiv) pollution level. As a result of the study, it was found that the toxicity rates are lowest in the autumn-winter period, while they are the highest during spring-summer.
