Monitoring of Water Quality in the Upper Basin of Litava River

Original language description

Morava River Board, s. e. as the governor of Litava basin is monitoring deteriorated physical and chemical indicators of main river in long term period, however exact source of pollution whether point or nonpoint is not known. Annually observed increased concentrations of phosphorus rate the Litava according to ČSN 75 7221 in V. class which means very heavily polluted water. The aim of this research is monitoring and chemical analysis of surface water quality in the upper part of Litava river basin in order to identify potential sources of pollution, which should be examined in detail within the scope of further investigation. Twelve sampling profiles were selected in the treatment area - eight profiles are directly on the stream of Litava river, four are on main tributaries. Monitoring program is performed by above-and-below approach, where sampling profiles are placed upstream and downstream of treatment area section. During three-month period of monitoring four water quality indicators were being measured in the field monthly: pH, temperature, dissolved oxygen and electrical conductivity. Also the samples were being taken and further analysed in the laboratory of water management for determination of total phosphorus, total nitrogen, nitrate nitrogen, ammonium nitrogen and chemical oxygen demand (COD). Results has been graphically demonstrated and evaluated according to Government order No. 401/2015 Coll., as amended and ČSN 75 7221. Chemical analysis confirmed that high concentration of total phosphorus is the major issue in upper basin of the Litava river, except spring areas.
