Sekundarni naslov:	Denitrifcation of drinking water
Sekundarni povzetek:	Most of the drinking water in Slovenia comes from groundwater. Unfortunately, in the majority of cases it is polluted because of industry, traffic and other human activities. One of the pollutants are nitrates. If they are present in drinking water in big concentrations (over 50 mg/l), they are harmful to human health. Especially babies are sensitive to the increasing quantity of nitrates and can get methemoglobinemia, commonly called »the blue baby syndrome«. Nitrogen comes into groundwater in different ways and in the form of different compounds. Approximately 80 % of it is in the form of ammonia compound, which - in water with enough oxygen - oxidizes to nitrates. The quantity of nitrates in groundwater is analysed and annually monitored by ARSO, the Agency of the Republic Slovenia for the Environment. The results of annual reports show that the north-east part of Slovenia is the one most loaded with nitrates. Most of the fault lies in intensive agricultural activity which during fertilization emits big quantities of nitrogen into the soil. In 1991, the EU enacted the Nitrates Directive. Slovenia as the future member of EU accepted the Directive and changed its regulation on entering dangerous materials and vegetable nutritions in ground accordingly. This defined the entire Slovenian territory as a sensitive area which required an operative programme with protection measures against the pollution of water with nitrates and pesticides from agriculture. This operational programme represents a preventive measure against the pollution of water with nitrates; where waters are already polluted, the pollution should be removed using different treatment methods, such as biochemical and physico-chemical, including reverse osmosis, electrodialysis and ion exchange.
