Legionella are a globally distributed aquatic bacterial genus. Since Legionella was first included in the Drinking Water Ordinance in 2011, there have been several amendments to date. In this study, test results ac- cording to Drinking Water Ordinance (TrinkwV) on Legionella of a North Ger- man drinking water test center from 2012 and 2016 were evaluated and pre- sented anonymously. The aim of the study was to investigate to what extent the amendment to the Drinking Water Ordinance has contributed to reducing the risk of contamination by Legionella.
