Waste water, pollution indicators, ANOVA, Kruskal-Wallis test, methods of multiple comparisons


The need to protect the environment from pollution is still one of the most important issues in modern world. It is generally accepted that the environment covers a broad scale of elements; including air, water, soil, flora and fauna, as well as human health and security, and these are to be protected which is a part of global goal to ensure permanent and sustainable development. Water is the basic substance and condition of human life on Earth. Until recently it  has been possible to satisfy humans´ requirements for water without any greater difficulties and that is thanks to regenerative and self-cleaning ability of water. The development of industries, agriculture, increasing number of human population and constant increase of life standards caused the pollution and decrease of water resources. The main goal is to point out possibilities of use of selected statistical methods for analysis and evaluation of waste water pollution indicators. While evaluating data of indicators from Sokoľansky Creek are to be used. The data are withdrawn from monthly reports covering the range of years from 2007 until 2011.
