Revised Water and Groundwater Directives (WFD/GWD) – PFAS24

In the proposal for the revised water (WFD) and groundwater directives (GWD; COM(2022) 540 final) there is a weighted sum of PFAS24 with a limit of 4.4 ng/l PFOA equivalents for both directives. Although the formal decision has not been taken, in Sweden SGU (Swe Geol Survey) has already chosen to introduce PFAS24 in the regulation SGU FS 2023:1 which includes threshold values for groundwater. The regulation entered into force on 1 March 23.

The majority of the 24 PFAS substances consist of perfluorinated carboxylates (PFCA; C4-C18) and sulfonates (PFSA; C4-C10). However, these are not exactly the same as in the drinking water directive (DWD) with its PFAS20 (or in SE SLV21) list. Other substances among PFAS24 consist of telomer alcohols (6:2 and 8:2 FTOH) and three PFAS ethers (PFECA), GenX, (A)DONA and C6O4. For C6O4 there has been no standard available due to patent rights. However, that situation has changed. We have now obtained the substance and can offer analysis also of this PFAS.

Eurofins new and expanded analysis packages

We have previously introduced two PFAS23 packages without C6O4. These packages are now expanded to include all of PFAS24 (without price adjustment) and are thus renamed. As before, there is a package for natural "clean" matrices (surface-, ground- and drinking water) and one for "unclean" (wastewater, process, leachate etc). As mentioned above, the lists for surface/ground and drinking water are not fully matched. Therefore, we are now introducing two new packages that combine PFAS24 and PFAS20/21 as well as PFOSA which is on the DK22 list for drinking and groundwater. Delivery time (TAT) is 10 working days and preferred volume is 2x100 ml in Eurofins PFAS bottles for all analytical packages.

Existing extended packages (incl. C6O4) with new name:

PLW8J: WFD/GWD prel PFAS24 (SGU FS 2023:1) (natural waters)
PLW8K: WFD/GWD prel PFAS24 (SGU FS 2023:1) (unclean waters)

New packages:

PLW9D: WFD/GWD prel PFAS24 and DWD20, SE21, DK22 (natural waters)
PLW9E: WFD/GWD prel PFAS24 and DWD20, SE21, DK22 (unclean waters)
