RIWA-Meuse has updated the lists with substances that are relevant for the production of drinking water from the river Meuse. The goal of this study is to evaluate and update the current lists of drinking water relevant and candidate drinking water relevant substances. Substances are considered as relevant if they fulfil a fixed set of criteria concerning i.e. their detection frequency, occurrence in concentrations above the ERM target value, (potential) removal by water treatment, toxicity, odour/taste threshold and public perception. To check if a substance fulfils the criteria monitoring data has to be available. Substances that are expected to be present in the Meuse, but are not monitored yet, are marked as candidate relevant substances. The criteria used for determining the relevance of substances for drinking water production have evolved over the years.
