Abstract

The water composition from water intakes of communities of Chernihiv region has been studied. It was established that the epidemiological safety, organoleptic properties, and sanitary-toxicological and physico-chemical indicators of the studied samples comply with the State Sanitary Norms and Rules 2.2.4-171-10. A distinctive feature of the water hydrochemical composition is the relatively low calcium ion content, especially in water intakes of Pryluky district, whereas the calcium ion content in water samples of Nizhyn district aligns with the standards of physiologically adequate water. Additionally, it was found that all samples comply with the standards for physiologically adequate water regarding Mg2+ ions content (10 - 50 mg/dm3), which is important for the cardiovascular system. At the same time, discrepancies with regulatory standards were identified regarding the concentration of total iron, manganese, ammonium and fluoride ions. The maximum deviation from the regulatory standard for total iron was established for Chernihiv district, with exceedances ranging from 6 to 25.4 times. Alongside the high iron content, significant excesses of Mn2+ and ammonium ions were recorded in the studied samples. Of the 15 studied water intakes, only 3 (20%) meet the physiologically adequate water standards for fluoride ions. While a fluoride ion deficiency is observed in the samples from Chernihiv district, all studied water intakes of Pryluky district are characterized by concentrations exceeding the standard by up to 1.2 times. A water treatment strategy which utilizes an integrated reagent-free water purification system Antares 777-1 has been proposed, and its effectiveness has been experimentally verified.
