Kurzfassung englisch:
The new water quality protection approach of the EC combines the control of emissions with
instream Environmental Quality Standards (=EQS). Since 1st April 2006 in Austria, beneath
EQS for 37 priority substances from list A of the EUROPEAN DERECTIVE 76/464 further 35
EQS for relevant chemical substances (list B) identified by a risk assessment have to be
reached to achieve the good ecological state in surface water (Edict for Water Quality
Standards, 2006). However, the practical assessment of these substances after point source
emissions is to some extent unclear at this time. In this paper two substances, namely 1)
ammonium (list B) and 2) nonylphenol, an endocrine disrupting compound (list A) are
presented to discuss i) the improvement of treatment efficiency due to the upgrade of a large
Waste Water Treatment Plant (=WWTP), ii) the relevance of mixing processes and modelling
as a method to control EQS after point source emissions and iii) the improvement of water
quality in the ambient surface waters (channel Donaukanal and the Danube). Presented data
were achieved from a three year monitoring programme conducted in the frame of the ECfounded
INTERREG project AdEQuaD and from the mixing model CORMIX.
