Abstract

This bachelor theses is focused on the influence of the village Štěpánovice on the quality of water of štěpánovice´s stream. Stream flowes throught the middle of the village, which is located on its both sides. Stream flows to the village from Štěpánovice pond, which biggest part is filled and reed – growned. That means that the pond is natural sewage disposal plant. ŠTěpánovice is small village and it wouldn´t be financially effective to build its own sewage disposal plant. In historical sources there could be found that the pipe drainage connected with the stream was made. Leak pipes are still visible and they serve to rain water drain. Due to the smell comming from the stream in the summer months, it is obvious that there is still small amount of waste water from the households leading to the stream. Take – off spots where located in order to keep the polution at the highest rate. The samples were taken from five spots, in front of and behind village Štěpánovice, at Jaroměřice nad Rokytnou village in front of the estuary to the pond and behind its drainage outlet. The fifth sample was taken from the pond. The results was compared according to the gouvermant regulation 23/2011 code of law (najdi si anglické znění toho zákona). The other legislative used for comparision of the theses parametres is ČSN 757221 Clasification of quality surfaře water. All samples were taken aproximately in the same time, in the same order for the duration of one year more spcificaly from January to December 2013.
