摘要：This paper presents the findings of a four-month study of samples of water taken from Lipkova River and artificial Lake (System 1) during 2012. The water samples, obtained from three different locations, underwent a study of their chemical, physical, and bacteriological parameters, which are good indicators of the quality of the water and aquatic ecosystems. Many agents affect the quality of surface and groundwater, the most important of which are anthropogenic pollutants introduced through the drainage of sewage systems that contain organic matter, soluble compounds of phosphorus, nitrogen, substances that initiate the process of eutrophication, pathogenic bacteria and viruses, heavy metals as well as substances that disrupt the natural state of water giving it a foul odour. The physical, chemical and bacteriological parameters are good indicators of surface and groundwater quality and the state of aquatic ecosystems.
