UBA PMT criteria published
The German Environment Agency (UBA, Umweltbundesamt) has published the assessment of "Persistence, Mobility and Toxicity (PMT)" with the desire to protect drinking water sources. Applying conservative criteria for PMT as defined by UBA, perchloroethylene (PER) and trichloroethylene (TRI) appear as number 2 and 3 on the report. UBA also aims to establish PMT as an equivalent concern to identify SVHC substance for authorisation under REACH. ECSA does not consider SVHC identification using PMT criteria as the appropriate tool to improve drinking water quality due to this being a pure hazard based approach and thus does not consider risk. TRI is already listed in Annex XIV (authorisation) and today PER is handled almost exclusively in closed systems with no intentional emission to water or soil. For further information see the ECSA position paper on PER here.
