Abstract

There is studied the ecological status of surface waters in Busk district. The attention is focused on the largest river Western Bug and its tributaries which essentially influence on the ecological condition. The analysis of hydrological monitoring in the basin of the Western Bug is done. Analysis of water pollution in the river is performed with use of fixed position state hydrological monitoring system postsThere are studied the data concerning pollution indicators for 2015 year and 3 seasons of 2016. A comparison of contamination in two points outside the district is carried out. There are considered river Poltva before its waters reach the district and flow into Western Bug and the river Western Bug after it lefts the district. The exceeding of the threshold limit values for some indicators is revealed. In all cases there is a slight excess of the TLV over the content of iron and ammonium ions. In Poltva have been considerable (3–6 times) exceeding the TLV for COD and BOD5, ammonium salt 8.4 times, total iron – 4.3 times, nitrites – in 6.75 times, suspended solids – 3.3 times, phenol – at 2.45 times. Therefore, the section of the city Buzka to the city Kamenka–Bug, Radekhiv bridge river water is not suitable for any water use. The self–cleaning of the water is happening within the district is and the second point of monitoring shows these indicators are within limitsThe largest source of organic pollutants and nutrients into Western Bug River is the river Poltva. Insufficiently treated sewage of Lviv increases the level of water contamination. In the district however there are also a source of pollution of surface water with ions of ammonium and iron. For their identification the further observation are required.
