“…In particular, in rural settlements, these figures are only 32.3 and 28.5%, respectively, compared to urban settlements with 77.5 and 76.5%, respectively (according to the State Statistics Service of Ukraine). As an alternative to centralized water supply, spring and well water is used; its quality is unsatisfactory, especially in terms of nitrate content (Gerasymchuk, 2015;Myslyva et al, 2016;Valerko, Herasymchuk, 2020;Romanchuk et al, 2021).…”

The research was conducted within the territories of rural settlements of Zhytomyr region. A total of 72 sources of non-centralized water supply were surveyed. Water quality was assessed by physical and chemical (pH, iron total, total water hardness) and toxicological (nitrites, nitrates, and ammonium) indicators, the content of which was compared with the norms given in the State Sanitary Regulations and Standards 2.2.4-171-10 “Hygienic Requirements for Drinking Water Intended for Human Consumption.” The assessment of drinking water quality was carried out in accordance with DSTU (National Standards of Ukraine) 4808:2007 and with the water quality index (WQI). It was found that the largest deviations from the norm among toxicological indicators were observed for nitrates – 63.9%. In terms of water quality classes according to DSTU 4808:2007, drinking water from sources of non-centralized water supply of villages showed the following distribution: 2.8% of the samples belonged to class 1 (excellent water quality), 72.2% to class 2, and 25% to class 3. According to WQI, 16.7% of the examined sources of non-centralized water supply had excellent water, 63.9% had good water, and 19.4% had poor water. Despite the fact that the water from the investigated sources of non-centralized water supply was of acceptable quality, it is impotable due to the excessive nitrate content. The results obtained show that there is a need for monitoring of drinking water quality from the sources of non-centralized water supply, especially in rural settlements that are not provided with centralized water supply.

One of the main problems of rural residential areas is to provide the local population with quality drinking water, which is a major factor influencing their health. To solve this problem, it is necessary to implement effective measures not only at the state level but also at the regional and local levels. The main purpose of decentralization of power is to transfer the power and appropriate financial resources to the lowest levels of local self-government, which makes it possible for created amalgamated communities to use these resources to solve the priority issues. However, to determine the ecological state of rural settlements in the subsystem of drinking water quality, it is necessary to assess its quality in the territory where the community is situated. The investigation was carried out in 15 rural settlements of the Teterivka amalgamated community of the amalgamated Zhytomyr district. 36 water samples were selected from the sources of non-centralized water supply. Water quality classes were determined following DSTU (National Standards of Ukraine) 4808:2007 “Sources of Centralized Drinking Water Supply. Hygienic and Environmental Requirements for Water Quality and Selection Rules”. As a result, it has been established that nitrates make the largest contribution to the pollution of drinking water. In 47% of the selected samples, the nitrate content on average exceeded the norm; and in 46.7% of the investigated settlements, water belongs to quality class 4, defined as “mediocre”, “partially potable” of undesirable quality. A critical situation was recorded in the villages of Mykhailivka, Nova Rudnia and Staroshiika, where the nitrate content in all selected samples of the well water exceeded the norm. On average, 61% of the selected water samples did not meet the standard and were below the standard. According to the pH indicator, the quality classes vary from “excellent”, very pure water grading to the class of “good”, pure water of the desired quality to “satisfactory”, slightly contaminated water of acceptable quality. The total iron content exceeded the standard in 5.6% of the selected samples.

Purpose. Assess the quality of drinking water of sources of decentralized water supply of rural settlements of Berezivka united territorial community of the enlarged Zhytomyr district. Methods. Field, laboratory-analytical, statistical. Results. As a result of research it is established that the greatest contribution to the pollution of drinking water is made by nitrates, the excess content of which was recorded on average in 50.7% of the selected samples, and in 57% of the studied settlements water belongs to quality class 4, "Limited" given undesirable quality. A critical situation was recorded in Bolyarka, Bondartsi, Dubovets and Cheremoshne villages, in which well water had increased content of nitrates in all selected samples. On average, 34% of the selected water samples do not meet the standard for the pH value in the direction of its reduction. In terms of pH, quality classes vary from "excellent", very clean to "good", clean water with a bias to the class of "satisfactory", slightly contaminated acceptable quality). The total iron content exceeded the standard by 6.6% of the selected samples. Conclusion. It is proved that the formation of the general class of water quality is significantly influenced by a group of general sanitary indicators, which is primarily due to the high content of nitrates in the studied sources of decentralized water supply. The calculation of the integrated ecological index of development of rural settlements according to the indicators of drinking water quality showed that such rural settlements as: Zamozhne and Sadky need priority attention; 11 settlements need improvement; only village of Vasylivka needs support at the same level.
