“…This is manifested in the excessive anthropogenic use of river basins (deforestation, the ploughing of more than 80% of the territory, residential, communal and industrial construction, etc. ), the increase in the volume of polluted economic, communal and industrial wastewater entering the river waters, the destruction of the river bed due to the intensification of water and erosion processes (Kotsiuba et al, 2022;Fryirs, 2017), the flowing of drainage water from unauthorized landfills into water bodies (Kotsiuba et al, 2023). It is small rivers that form the hydrochemical composition and water quality of the medium and large rivers of Ukraine.…”

Aquatic ecosystems are perpetually exposed to anthropogenic sources of pollution, wherein the quality of subterranean and surface waters undergoes influence from both natural and anthropogenic processes. This interaction results in environmental predicaments and, occasionally, environmental crises. Small rivers, in particular, bear a pronounced impact from human interventions on the environment. The investigation undertaken by the researchers commenced in 2021 with the primary objective of scrutinizing the ecological condition of the Irsha River. Regrettably, due to the military aggression of the Russian Federation, the regions through which the river courses were temporarily occupied, subjecting it to considerable anthropogenic disturbances. Specifically, two bridges spanning the Irsha River in the Malyn area were demolished, and military operations transpired along the riverbanks, leading to the accumulation of damaged military equipment. Consequently, it was deemed imperative during the course of our study to conduct an analysis of the natural water in the Irsha River subsequent to the military activities. The outcomes of a comprehensive assessment of surface water quality, employing a graphical method, revealed that, during the period of 2021-2022, the river waters within the Irsha River exhibited an overall failure to meet quality standards in both monitoring locations. Elevated values of Maximum Permissible Concentration (MPC) exceeding the norm were noted for the Chemical Oxygen Demand (COD) indicator, the dissolved oxygen indicator, as well as the general iron and iron of permanganate oxidizability parameters in both samples. The highest degree of pollution was discerned in the Malyn Reservoir, whereas the Irsha Reservoir manifested comparatively lower pollution levels in the aquatic environment.

The purpose of the study was to assess the state of ecological development of rural rural areas of the amalgamated territorial communities of Zhytomyr district based on drinking water quality indicators of non-centralised water supply sources to ensure their sustainable development. It was found that the average pH value was within the current standard, which indicates an excellent environmental condition for this indicator. The average content of nitrates in drinking water, which in all the studied communities exceeded the standard by 1.4 to 3.5 times, was assessed at only one point. The average concentration of total iron exceeded the current standard by 1.9 times only in the rural settlements of the Liubar community. Satisfactory water quality, in terms of total iron content, was recorded in 50 per cent of the surveyed communities. In 70 per cent of the studied communities, the average value of total hardness was recorded at a level higher than 7.0 mmol/dm3, which indicates, according to European legislation, a poor condition of drinking water. Thus, having assessed the ecological state of rural areas in terms of drinking water quality, it was found that most of the studied communities have a satisfactory state of the territories, as the total number of points varied between 2.25-3.3 points. And the greatest contribution to the decline in the level of environmental development of rural settlements is made by the indicators of nitrate content in drinking water and its hardness.
