The paper considers the impact of urbanized areas on the state of water bodies. The impact of various types of anthropogenic activities on water bodies located in cities was shown. In towns, there is worse water resource management than in large cities and the necessity of conducting more detailed research. Using the method of direct conductometry, a spatio-temporal study of the ecological state of water bodies located within the detached objects of the urbanized territory of the Ukraine was carried out using the example of Popasna town. It was shown that fluctuations in the electrical conductivity of these bodies are mainly due to the influence of surface runoff. It was found that in all studied ponds there was a significant drop in the electrical conductivity of water in March 2021, followed by an increase and stabilization in April and May 2021, the characteristic values of electrical conductivity range from 200 to 2900 μS, the relative standard deviation did not exceed 1.5%. The necessity of conducting further, more detailed study of the features of the influence of surface runoff on the water condition in the studied ponds was shown for the purpose of rational management of these water bodies.

W pracy przedstawiono wyniki badań składu gatunkowego wodnych makrofitów rzeki Turia, biegnącej na terytorium Polesia Wołyńskiego. Inwentaryzację roślin przeprowadzono w czterech punktach obserwacyjnych, począwszy od źródła do ujścia rzeki, w okresie od maja do września 2017 roku. Oznaczono 59 gatunków roślin, w tym 41 gatunków wskaźnikowych i obliczono Makrofitowy Indeks Rzeczny (MIR) dla rzeki Turia zgodnie z "Makrofitową Metodą Oceny Rzek”. Ustalono, że stan ekologiczny wód w górnym biegu rzeki (wieś Zaturce) jest umiarkowany, w średnim biegu rzeki (miasto Kowel - stanowisko koło mostu) wzrasta do stanu dobrego, natomiast na następnych stanowiskach pogarsza się i w pobliżu wsi Bachiw oraz we wsi Buzaky (dolny bieg rzeki) ponownie osiąga stan umiarkowany.

The results of the study of the species composition of the aquatic macrophytes of the Turija River, passing through the territory of the Volyn Polissya, are presented. The research was carried out on four observation points, from May to September 2017, along the river - from the river source to the river mouth. In total, 59 plant species were identified, including 41 species regarded as indicators of environmental conditions. The paramater known as «Makrofitowy Indeks Rzeczny (MIR)» was also calculated. It was found that the ecological condition of the water in upper part of the river (Zaturtsi village) is satisfactory, in the middle part of the river (Kovel, near the bridge) becomes better. In the next research points, such as the Bakhiv village, in the lower part of the river, and near the Buzaky village will reach the level of condition as satisfactory.
