Groundwater sources were mainly formed outside populated areas, but the illegal building of settlements, came in the immediate vicinity of the source. In such situations, the provisions of the sanitary protection of existing water sources, it is necessary to record and analyze the existence of potential contaminants, andto define the safety of sources. Problems are complicated by the fact that in Bosnia and Herzegovina there are currently only six of the vessels for the treatment of municipal wastewater, which included less than 3% of the settlements, and that the zone of s anitary protection i n many cases, inadequately performed This paper analyzes the complex issue of the protection of groundwater sources in populated areas. Key words: groundwater sources, urban environment, pollution, sanitary protection zones 1. PROTECTION OF GROUNDWATER At the Federation of Bosnia and Herzegovina (FBiH) 73.2% of the population is connected to a central water supply system where water is continuously reviews the safety. Central City water supply in all the municipalities are the largest part of water infrastructure. Most of the central source of water supply has regulated first and second zone of sanitary protection, as well as modern way of chlorination. However, a central water supply facilities in the Federation have defined only the first zone of sanitary protection. Traditionally, local and mostly rural, are supplied from our own wells and local water supply. In these areas, chlorination of drinking water is not satisfactory. The second zone of sanitary protection is generally not defined, and individual water supply facilities (wells, cisterns) , are often not regulated by any strict sanitary protection zone. Control of drinking water is usually reduced to a periodic review of the basic physico- chemical and microbiological parameters. Because of this, the law defines the obligations to be
