Hirnyk Drinking water quality of decentralized water supply in rural settlements of the Forest-steppe zone

Abstract

The purpose of the article was, on the basis of monitoring studies, to establish the peculiarities of the state of natural waters in the agrolandscapes of the Forest-steppe zone under various agrotechnogenic loads. The study used the method of agroecological monitoring and laboratory (methods of chemical, physico-chemical analysis using modern methods of atomic absorption spectrophotometry, flame photometry in accordance with the requirements of the quality management system, DSTU 3973-2000). The study of the state of natural water in 2015–2020 was conducted by the staff of the Department of Agroecology and analytical research of the NSC “Institute of Agriculture of NAAS” in the agro-landscapes of the Right Bank Forest-Steppe in Kyiv region: in Kyiv-Sviatoshynskyi district - v. Gatne, v. Kruglik,v. Kryukivshchyna, v. Vita Poshtova, in Vasylkiv district -v. Dzvinkove, in the Tarashchansky district - the v. Rizhky, in the Left-Bank Forest-Steppe - in the Poltava region, Shishatsky district, v. Manachynivka. The results of water analysis at stationary points of the Right-Bank and Left-Bank Forest-Steppe indicate that none of them was distinguished by the stability of physicochemical and chemical indicators, the quality of drinking water in rural settlements directly depends on the ecological state of agricultural landscapes and individual farms. The state of drinking water in the system of decentralized water supply of rural settlements in most cases did not correspond to the standards in force in Ukraine, which indicates a high anthropogenic load on agricultural landscapes, an insufficient level of ecological culture and the need for monitoring. The issue of monitoring natural waters and reducing the risks of their pollution is important from the point of view of improving the quality of drinking water in rural areas.
