Protection of drinking water resources from PMT/vPvM substances: Revised guidance for REACH registrants on the identification of these substances of very high concern (SVHC). Only 1.9 % of the unique chemical structures in the REACH registration database fall in the new CLP hazard classes PMT and vPvM. However, for a total of 64 % no final assessment was achieved, either due to lack of test data (41 %) or due to ambiguous assessment (23 %). These guidance and methods can be used immediately by REACH registrants to ensure the safety of their substances, to close data gaps and, if necessary, to use safer alternatives, or to implement risk mitigation measures (RMMs).

Protecting the sources of our drinking water from any threats caused by chemicals is of the utmost importance. A strategy is needed in order to allow Europe’s chemical industry to continue to innovate while ensuring the protection of the water cycle. The German Environment Agency ( UBA ) is carrying out an initiative to identify those substances that are persistent (P) in the environment, mobile (M) in the water cycle (PM substances), and additionally toxicity (T) to human health (PMT substances). The proposed criteria will assist registrants in fulfilling their responsibility of guaranteeing the safe use of chemicals under the EU’s chemical regulation “REACH” (Regulation EC No 1907/2006). Veröffentlicht in Position.
Herein a review of substances detected in drinking water and groundwater found that 43 percent of them are registered under EU REACH Regulation (EC) No 1907/2006. In addition, a PMT/vPvM assessment was applied to all REACH registered substances (as of May 2017). Persistent, Mobile and Toxic (PMT) and very Persistent, very Mobile (vPvM) substances pose an intrinsic hazard to the sources of our drinking water. Data quality considerations are included, along with a preliminary emission assessment and cost/benefit considerations. Of the complete list of PMT/vPvM substances, 122 chemical constituents are prioritized for further investigation to assess the need for introducing risk management measures.

A broad literature review (55 studies published between 2000 and 2019) now shows that 639 chemicals are already known as contaminants in river bank filtrate (114 substances), groundwater (338 substances), raw water (212 substances) or drinking water (385 substances). The literature review carried out by the German Environment Agency reveals: Every second substance that contaminates our drinking water resources is registered under REACH , of which 24 % fall in the new CLP hazard classes PMT and vPvM. Considering only the raw water, the proportion even rises to 32 %. In the REACH registration database, the proportion of PMT/vPvM substances based on CLP criteria is only 1.9 %.

Chemicals with a specific combination of intrinsic substance properties pose a hazard to the sources of our drinking water, including substances that are very persistent (vP) in the environment and very mobile (vM) in the aquatic environment as well as substances that are persistent (P), mobile (M), and toxic (T). This publication presents the result of the scientific and technical development of the PMT/vPvM criteria under EU REACH Regulation (EC) No 1907/2006. The scientific and regulatory considerations include (1) monitoring data, (2) simulation and model studies and (3) impact considerations. This can be considered a ready-to-use tool for industry to identify PMT/vPvM substances. Veröffentlicht in Texte | 127/2019.
PFAS only the tip of the iceberg: Each water sample was contaminated with mobile forever chemicals such as TFA, PFPrA or TFMS. But also 26 of the 34 non-fluorinated PMT/vPvM substances analysed were detected, including 1H benzotriazole, 1,4-dioxane, melamine, cyanuric acid and diphenyl guanidine. A representative survey of 27 water laboratories in Germany (twelve commercial laboratories, eleven laboratories of a federal state and 4 laboratories of water suppliers) now shows that out of 79 requested PMT/vPvM substances 60 % are not monitored due to lack of analytics (“analytical gap”) or lack of monitoring (“monitoring gap”). At the same time, the research project of the German Environment Agency shows that 51 % of these 79 PMT/vPvM substances cannot be removed from raw water with activated carbon filters or ozone. The PMT/vPvM prioritisation framework supports REACH registrants, regulators, researchers and the water sector to take immediate action to protect drinking water resources.

For the first time a comprehensive list of 167 REACH registered substances were assessed with respect to their intrinsic substance properties persistence in the aquatic environment, mobility in the aquatic environment and toxicity. The results of this project will support the ongoing discussion to define PMT criteria under REACH. The present study provides a consolidated list of (in order of priority) assessed PaqMT substances (9 substances), assessed PaqM substances with suspected T (20 substances) and further 93 suspected PaqMT substances. A total of 134 substances are recommended to the German Environment Agency ( UBA ) for further investigation and scientific and regulatory scrutiny. Veröffentlicht in Texte | 09/2018.
Protecting the aquatic environment from chemicals for future generations: The UBA list of 259 PMT/vPvM substances (based on the new CLP criteria) in the REACH registration database that are hazardous to our drinking water resources and must not be emitted into the environment. Registrants and downstream users (DSUs) can act immediately to minimise emissions throughout the life cycle of these substances of very high concern (SVHC) to protect the aquatic environment for future generations.

Dies ist eine Aktualisierung der Leitlinien und Methoden für die Identifizierung und Bewertung von persistenten, mobilen und toxischen (PMT), sowie sehr persistenten und sehr mobilen (vPvM) Stoffen aus dem Jahr 2019. Die PMT/vPvM-Bewertung in diesem Bericht verwendet ein Ampelfarbschema, um die Schlussfolgerung und das verbundene Unsicherheitsniveau darzustellen. Im September 2019 befanden sich 22400 Stoffe in der REACH-Registrierungsdatenbank, aus denen 13405 einzigartige chemische Strukturen identifiziert und bewertet werden konnten. Über 27 % (3595 von 13405) erfüllten nicht die PMT/vPvM-Kriterien. Für insgesamt 67 % (9047 von 13405) war keine abschließende Bewertung möglich, entweder aufgrund unzureichender Daten (41 %; 5542 von 13405) oder aufgrund nicht eindeutiger Bewertungen (26 %; 3504 von 13405). Für 3,1 % (421 von 13405) waren zwar die Kriterien für Persistenz und Mobilität erfüllten, aber es fehlt eine abschließende Bewertung, ob das T-Kriterium erfüllt ist. Nur 2,6 % (343 von 13405) erfüllten die PMT/vPvM-Kriterien. Die Leitlinien und Methoden wurden angewendet auf REACH-registrierte Stoffe sowohl unter Einsatz der von Neumann und Schliebner (2019), veröffentlicht als UBA TEXTE 127/2019, im Rahmen von REACH vorgeschlagenen PMT/vPvM-Kriterien, als auch unter Einsatz der von der Europäischen Kommission im Jahr 2021 im Rahmen von CLP vorgeschlagenen Kriterien. Bei Verwendung der von der Europäischen Kommission vorgeschlagenen weniger strengen PMT/vPvM-Kriterien reduziert sich die Zahl der identifizierten PMT/vPvM-Stoffe auf 1,9 % (259 von 13405). Dass bereits 4358 von 13405 einzigartigen chemischen Strukturen in der REACH Registrierungsdatenbank mit diesen Leitlinien bewertet werden könnten, deutet darauf hin, dass die PMT/vPvM-Kriterien für die Integration in die CLP- und REACH-Verordnung geeignet sind. Allerdings Keine endgültige PMT/vPvM-Schlussfolgerung für 67 % (9047 von 13405) bestätigt jedoch, dass es auch erhebliche Datenlücken in der REACH-Registrierungsdatenbank gibt, die sofort durch eine Aktualisierung der bestehenden REACH-Registrierungsanforderungen behoben werden sollten. Diese Leitlinien und Methoden können von REACH-Registranten sofort angewendet werden, um die Sicherheit ihrer Stoffe zu gewährleisten, Datenlücken zu schließen und ggf. sicherere Alternativen zu verwenden oder Risikominderungsmaßnahmen (RMM) zu implementieren. Darüber hinaus können die EU-Mitgliedstaaten und die ECHA sie bei der Identifizierung von PMT/vPvM-Stoffen als besonders besorgniserregende Stoffe (SVHC) gemäß Artikel 57f der REACH anwenden.
