HYDROCHEMICAL ANALYSIS AND RATIONAL USE OF THE NATURAL WATERS OF THE MYKHAILIVKA RIVER

Abstract

Control over the rational use of natural waters, monitoring the ecological state of the basinand the chemical composition oft he water of the small Mykhailivka River, including hydrochemical indicator soft water quality, that is part of the general ecological analysis of the state of water in this reservoir, is relevantin the conditions of growing anthropogenic load. The research was carried out on the basis of the material sof the survey of the state of the Mykhailivka River basin, the methods of collecting and analyzing statistical information, potentiometric and photometric analyzes of determining the content of nitrogen and phosphorus compounds. Mykhailivka is a river in the Sarnen district, Rivne region. Left tributary of the Sluch River, the Pripyat Riverbasin. The lengt his 33 km. The water catchmentareais 128 km2, it flows out of the swamp massif 4 kmaway, to the east of the village of Tutovichi. It flows to the northeast: inTutovychy, Remchytsy, Lyubikovychy, Strilsk. It flows into the Sluch river in the village of Strelska. The river has been straightened along its entire length and transformed into the main channel of the drainage system. The floodplain is swampy and wide. The slope of the riveris 0.53 m/km. Wetook a series of samples for the study of hydrochemicalin dicators of the surface water sof the Mykhailivka Riverin four seasons (winter, spring, summer, autumn) of 2021–2022 years in three areas (1 – in the upstream of the river (Tutovychi village), 2 – near the village Remchitsi in the middle course of the river, 3 – nearthe village of Strilsk in the lower course of the river). Based on the conducted research, it was established that the water quality in the reservoiris satisfactory. We recorded an excess of phosphorus concentration. It has been established that water resources are currently being used sparingly. Water is mainly taken for cultural domesticuse and fish farming. Exceeding the norms of hydrochemical parameters was not recorded. The ecological condition of the Mykhailivka river basinis satisfactory.
