Substances relevant for drinking water

PMT/vPvM substances: Identification and Regulation under REACH

Word clouds on REACH and PMT substances

The German Environment Agency and DVGW-Technologiezentrum Wasser (German Water Centre) have been highly active in determining the drinking water relevance of anthropogenic chemicals based on their intrinsic substance properties or from the data submitted for the substance registration. It is therefore a good idea to join forces for preventative resource protection!

For the preventative protection of the environment and human health, the minimising rule of the German Drinking Water Ordinance states that chemicals, which may end up in raw water for drinking water production, should not be discharged to surface water and groundwater and that their concentrations in the water bodies must be kept as low as reasonably achievable (ALARA principle). Nevertheless, there are anthropogenic substances that can be detected in treated drinking water. Usually these substances belong to the group of the so-called PMT/vPvM-compounds (very persistent, mobile substances that may or may not bear a potential hazard).

The aim of this project is to identify substances that are relevant to drinking water and promote the hazard-based management under REACH. Regulatory management option analysis (RMOA) will be established and findings gathered on the occurrence of anthropogenic substances in raw and drinking water. Additionally, water samples will be analysed for selected persistent and mobile substances. The objective is to combine the results and findings to propose approx. 10 substances to the Federal Environment Agency for regulation under REACH.
