Priority Substances from UWWTPs
Austrian Case study1
Kopenhagen 16.9.2010
„Starting point“

WFD Annex II 1.4: Collection and maintainance of information about significant anthropogenic pressures
Austrian Water Act,§ 59a: Electronic register of pressures and impacts Austrian ordinance for emissions register - surface water bodies (EMREG-OW)
Water quality ordinace - Surface water – Chemistry (72 Substances and groups of substances)
UWWTPs in Austria:
