The quality of water sources in the Czech Republic

The following bachelor thesis on the subject of The quality of water sources in the Czech Republic is supposed to introduce its readers to both historical development and current state of surface water quality in the Czech Republic. The works methodology is creation of a literature review of available scientific literature and especially Reports on surface water quality in particular river basins. The first part briefly describes Czech hydrological network and basic water quality indicators. The second part deals with the development of surface water quality in particular river basins. Another part of the work describes legal measures concerning surface water protection. In the last century, surface water contamination was considered one of the biggest environmental problems in our country. Waste water flowing into surface water were not perfectly treated and often werent treated at all. Because of this and also because of intense industry development, surface water was highly polluted. It wasnt until 1989, when the surface water quality improved significantly, mainly due to reduction of contaminants discharge, waste water treatment plants and sewerage system construction and development. Main danger for quality of rivers after 1989 were floods in 1997 and 2002, during which water treatment plants outage were often and dangerous chemicals were leaking from factories. The main finding of this work is the fact that quality of surface water in Czech Republic is much better than in the last century. However, it is still needed, that we focus on smaller rivers which are being endangered the most by discharge of contaminants from villages that dont have their own waste water treatment plants
