The figawa-work group water analytics mandates the Institute for Hygiene and Public Health of University of Bonn (ihph) with a followup study on the occurrence of legionellae in drinking water systems. The research project shall deliver more detailed information than the prior status analysis. First results will be exspected in the end of 2017.
The work group came up with more than 1,000,000 drinking water datasets giving a global overview of the hygienic situation in domestic water systems in Germany.
Soon after the first results were published, the quality of the data that was assessed was criticized by a variety of water experts. Many water samples could not be assigned to a specific installation. On many protocols the information about the sample and water temperature was lacking. A certain set of data could not be processed by the labs IT, for instance the location of drinking water installation if the address differed from the postal adress of the owner or operator.
To eliminate those deficits the figawa decided in January 2017 to order a followup study with a better set of variables to be examined and assessed. The final results are expected to be published in November 2017.
