The bachelor thesis deals with an issue of protective areas of water resources, specifically ground water resources, which supply a drinkable water of Dlouhá Lhota. The thesis is separated into a several chapters. Literature research is the first chapter and it describes water management legislation, it also deals with an issue of water quality, water pollution and ways to protect watercourses. In next chapters there is a characteristic of the area, in which there are assessments of natural and water management conditions. The thesis detailed describes water resource and its parameters. After that, there is an analysis of risk, which endanger water quality, water quantity and health of water resources. With help of a few graphs, there are evaluated some water quality values: pH, colour, turbidity, ammonium ions, nitrates, nitrites, manganese, iron and CHSKMn. Based on these values there are some proposed measures, which should improve water quality of ground water resource of Dlouhá Lhota. Zones of hygienic protection ensure the protection of water source, which was established in the 80's of last century and now these are inconvenient.

Chocholáčková, Zuzana
The diploma thesis deals with wastewater and rating of efficiency of the wastewater treatment plant (WTP) Hodonín, which cleans communal and industrial wastewaters. Chapter of the literary research describes law regulations dealing with wastewaters, furthermore deals with water pollution, wastewater and wastewater treatment plant technological equipment. Next chapter contains characteristics interest area, its natural and economic conditions and traffic description in WTP Hodonín. I calculated efficiency for selected indexes for the period since 2003 to 2018 from the provided database from company Vodovody a kanalizace Hodonín, a.s.. This values of efficiency and values of concentration of these indexes were compared with emission standards stated in relevant government orders and processed to charts. Average values of efficiency in the observed period were always beyond required limits. Due to my own monitoring, were stated values of biochemical oxygen demand, total nitrogen, total phosphorus, nitrate nitrogen, ammoniacal nitrogen and orthophosphates by spectrophotometry. I calculated efficiency of cleaning from these values and compared them with relevant limits. The results showed that efficiency of cleaning in WTP Hodonín is about 15% higher than it should be due to legislative.
