[Water quality: legislation--our country and European Union].

Water quality and water supply system in our country are primarily related to inadequate environment management in 1990s, due to poor economic situation in the country and insufficient investments. With a view to improve conditions of environment, strategic documents at various levels have been adopted. One of these, water-supply basis for Serbia 2002-2012, was adopted by Government of the Republic of Serbia in 2002, which defined basic strategy for water management. Law on Environment Protection (2004) provides basis and possibility of further applicability of EU directions complying with respective standards. Apparent trend in this field is tendency of setting up certain standards for each purpose (Council Directive 75/440/EEC, Council Directive 76/160/EEC) as well as for some types of water systems (rivers, lakes, ground waters). Our paper presents the most important regulations of the Republic Serbia and EU in the field of water quality management, control of water quality in our country, monitoring, that would, followed by adequate information system, contribute to quality improvement of ambient and drinking waters.
