Abstract

The proposed document will specify a method for the determination of the sum of selected perfluoroalkyl and polyfluoroalkyl substances (PFAS) in drinking water using liquid chromatography mass spectrometry (LC MS/MS).The method covers at least the substances needed for the calculation of the 'Sum of PFASs ' according to Annex III, part B, point 3 of the new European drinking water directive (draft). Currently the DWD comprises the perfluoralkyl acids C4 to C13 as well as the perfluoralkyl sulfonic acids C4 to C13.Other matrices like groundwater and additional substances like HFPO-DA (GenX) and ADONA or perfluoralkansulfonamides (FASA) will be included if possible. The lower application range of the method can vary depending on the sensitivity of the equipment used and the matrix of the sample. For most compounds to which this document applies ≥0,2 ng/l as limit of quantification can be achieved. Actual levels can depend on the blank levels realized by individual laboratory.The applicability of the method to further substances, not listed in the annex of the DWD, or to further types of water is not excluded, but is intended to be validated separately for each individual case.
