Verordnung des Bundesministers fur Gesundheit und öffentlicher Dienst vom 15. November 1989 über den Nitratgehalt im Trinkwasser (Trinkwasser-Nitratverordnung). Bundesgesetzblatt für die Republik Osterreich, Nr. 557/1989

This regulation sets the legal limits for nitrate levels allowed in drinking water. Its primary purpose is to protect public health by ensuring that water supplies do not contain harmful concentrations of nitrates, which can occur due to agricultural runoff or industrial pollution. This affects water suppliers, public health authorities, and the agricultural sector in Austria, as it mandates strict monitoring and quality standards for all potable water sources.
