- In fresh waters and waste waters (programmes 59 "Perfluorinated compounds in fresh waters" and 59A "Perfluorinated compounds in waste waters") : 9 PFAS and 2 US PFAS are added to the PFAS  already provided in order to meet the requirements of the Water-Framework Directive. For each PFAS (except TFA and TFMS), participants will be able to report results for the linear isomers but also for the sum of linear and branched isomers.

- In sediments and soil: new programmes 48 "Perfluorinated compounds in solid matrices" with the quantification of 21 PFAS
