Drinking water monitoring
List of the 20 PFAS monitored in drinking water
Monitoring of water intended for human consumption includes a parameter corresponding to the sum of the concentrations of 20 per- and polyfluoroalkyl substances.
What is the regulatory limit?
The parameter corresponding to the sum of the 20 PFAS has a parametric value of 0.10 µg/L, equivalent to 100 ng/L.

Individual analysis and calculation of the sum
Each compound is tested and quantified individually. The report presents the results for each substance, together with the information required to assess the Sum of PFAS parameter.
The limits of quantification must be appropriate for the required level of monitoring and the value applicable to the sum of the concentrations.
Which types of water should be tested for these PFAS?
- distributed drinking water;
- treated water at the treatment plant outlet;
- raw water used for drinking water production;
- water from abstraction points;
- groundwater;
- surface water used as a drinking water resource.
