Official Immissions Measuring Network 2012-2016

According to the Quality Target Ordinance Ecology Surface Waters (BGBl. II No 99/2010 idgF), the general conditions of the physico-chemical quality components are assessed on the basis of the parameters temperature, biological oxygen demand (oxygen mitigation — BSB5), dissolved organic carbon (DOC), oxygen saturation (O2 %), pH value, orthophosphate (PO4-P), nitrate (NO3-N) and chloride. The results of sampling from 2012 to 2016 at Upper Austrian flowing waters — sampling points of the Official Immissions Measuring Network (AIM) — are displayed. The assessment is carried out via an assignment to one of the 5 status classes: very good, good, moderate, unsatisfactory, bad; The given environmental objective is to achieve or maintain at least the status class.
