At the sites of the Austrian monitoring network, regular sampling of ground and surface water has been undertaken, as well as analysis for a wide range of inorganic and organic parameters, since the early 1990s. You can find the water quality monitoring results here.. The Institute of Bioanalytics and Agro-Metabolomics of IFA-Tulln has organised regular interlaboratory comparisons for external quality assurance of water analysis on behalf of the Federal Ministry of Agriculture, Regions and Tourism since 1994. This proficiency testing scheme covers a wide range of inorganic and organic parameters and any laboratory can participate. Until the start of the cooperation with the Agency Austria, synthetic water samples have been used as test samples, with concentrations comparable to natural waters.

Cooperation IFA-Tulln - Environment Agency Austria (Umweltbundesamt GmbH)

Since 2013, interlaboratory comparisons with natural samples (ground, surface, waste and drinking water, partly spiked) have been on offer covering nearly all parameter groups. This service is possible as a result of the cooperation between IFA-Tulln and the Environment Agency Austria.

Interlaboratory comparisons with natural water samples

Registration is processed by the IFA-Tulln. For each interlaboratory comparison, two water samples of different concentrations are dispatched by the Environment Agency Austria. The homogeneity and stability of the samples are checked as a matter of course. Clear and anonymous test results - which are common practice with interlaboratory comparisons using synthetic water samples - will be provided swiftly also for natural water samples, including z-Scores and confirmation of participation.

Target values will be available on the website shortly after the closing date. All reports will be published here, too.
