PFAS in Saint-Père-sur-Loire's tap water: 9 ng/L, 18x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
18× above our health benchmark
0.5 ng/L is our benchmark, not an official limit. Same EFSA method as Sweden, Denmark and the Netherlands, but stricter. It's a yearly average, compared here with the latest check.
Sample taken in Sully-sur-Loire, on the same distribution network as Saint-Père-sur-Loire (SULLY SUR LOIRE-ST PERE SUR LOIRE). The health authority samples one tap per network; a network carries the same treated water everywhere.
More about this result
The US also limits PFOA and PFOS to 4 ng/L each, per substance.
Substances below the detection limit count as 0, so the real total may be higher.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

Frequently asked questions
Is tap water in Saint-Père-sur-Loire safe to drink?
Yes. At the check on 15 January 2026, the tap water in Saint-Père-sur-Loire was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés. La teneur en chlorure de vinyle monomère ne vaut que pour le secteur où elle a été mesurée. La présence de cette molécule est directement liée à la présence de canalisation en polychlorure de vinyle posée avant 1980, cette valeur n'est pas représentative de la qualité de l'eau pour l'ensemble des consommateurs du réseau de distribution. Les teneurs en plomb, cuivre et nickel ne valent que pour le point d'utilisation où elles ont été respectivement mesurées. Compte tenu de l'influence du réseau de distribution d'eau (réseau intérieur et éventuellement branchement public) sur la dissolution des métaux, ces valeurs ne sont pas représentatives de la qualité de l'eau pour l'ensemble des consommateurs du réseau de distribution (circulaire DGS/SD7A n°45 du 5 février 2004).”
How high are PFAS levels in Saint-Père-sur-Loire's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 42 ng/L. The EU limit is 100 ng/L, so this water is at 42 % of the limit. (below the EU limit)
Does the water in Saint-Père-sur-Loire also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 9 ng/L. That is 2.3 times Sweden's legal limit of 4 ng/L, in force since 2026. Germany will set a similar one in 2028. The water still passes the current EU legal limit (100 ng/L for the total of 20 PFAS).
Are PFAS levels rising in Saint-Père-sur-Loire's tap water?
Calculated PFAS-4 values are listed in the table. The chart uses laboratory-published sum-of-20 results; there are too few laboratory-published PFAS-4 sums for the existing trend calculation.
How hard is the water in Saint-Père-sur-Loire?
The water hardness in Saint-Père-sur-Loire is 16.2 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
