Pursuant to the 2nd amendment of the German Drinking Water Ordinance (TrinkwV), since December 2012 the German Environment Agency (Umweltbundesamt – UBA ) has been tasked with stipulating mandatory evaluation criteria for materials and substances that come into contact with drinking water. Previously, UBA has issued guidelines and recommendations which were less legally binding. Since the amendmen... read more

Drinking water which has been treated in a waterworks or drawn directly from an on-site well must meet the requirements of the German Drinking Water Ordinance all the way to the tap. Its distribution via the water company’s mains and the drinking water systems of individual buildings brings it into contact with a large range of substances. It is essential for the quality not to be impaired. read more

The four Member States (MS) Germany, France, the Netherlands and the United Kingdom of Great Britain and Northern Ireland in 2011 have agreed on collaboration in the harmonization of tests for the hygienic suitability of products in contact with drinking-water. These 4MS-collaboration efforts have evolved successfully and now are termed “4MS-Initiative” (4MSI) in view of extension perspectives. read more

On this page, you will find an overview of reference values for assessing the human toxicological and ecotoxicological risk of micropollutants in water bodies.

Between 2016 and 2019, the UBA carried out several public consultations to ensure a wide agreement on the PMT/vPvM criteria. This led to the publication of the result of the scientific and technical development of PMT/vPvM criteria and guidelines for their assessment under REACH, which were unveiled at the 30th Caracal meeting in 2019 (Doc. CACS/MS/19/2019; CARACAL-30; 01 - 02 July 2019). read more

Between 2009-2015, the UBA scientifically developed, under the EU´s chemical legislation REACH, new criteria to identify substances which have intrinsic properties that indicate a hazard to the sources of our drinking water. Chemical safety experts and regulators agreed on the need to precautionarily identify such substances of concern. This is considered as the emergence of the PMT/vPvM criteria. read more
