Taking into account that groundwater is the main source of drinking water in the Union, it is essential to ensure that the quality standards set in Directive 2006/118/EC support the achievement of the parametric values set for drinking water under Directive (EU) 2020/2184. Although it might be appropriate to harmonise the standards for PFAS, it has recently been demonstrated that the parametric value relating to the sum of the 20 PFAS, as listed in Part B, point 3, of Annex III to Directive (EU) 2020/2184, is not in line with the latest scientific developments with respect to the list of PFAS to be given priority consideration, the toxicity of these substances and the variability of toxicity between the substances in this family. In the absence of a complete and final agreement on PFAS standards, a quality standard for the group of 20 PFAS, as listed in Part B, point 3, of Annex III to Directive (EU) 2020/2184, is set out in Annex I of Directive 2006/118/EC, by way of reference to the parametric value for that group in Directive (EU) 2020/2184 in order to ensure that any change to the composition of that group or that value be automatically incorporated into Directive 2006/118/EC. To take account of the most recent scientific knowledge, a quality standard for the sum of the four most problematic PFAS should be added to Annex I to Directive 2006/118/EC in accordance with the value proposed by the European Food Safety Authority (EFSA). For the same reason, it is of utmost importance that the parametric values for PFAS in Directive (EU) 2020/2184 be promptly reviewed and revised as appropriate and, in such a case that the quality standards in Annex I to Directive 2006/118/EC also be aligned.
