PFAS in Courtillers's tap water: 7.6 ng/L, 15.2x our 0.5 ng/L benchmark

PFAS in drinking water
15.2× 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 Sablé-sur-Sarthe, on the same distribution network as Courtillers (SABLE SUR SARTHE). 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).

In Courtillers, the 4 most closely watched PFAS (PFAS-4) add up to 7.6 ng/L (0.0076 µg/L) at the latest PFAS check on 1 July 2026. That's 15.2 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 68 ng/L (0.068 µg/L), below the EU legal limit (100 ng/L). Sampled in Sablé-sur-Sarthe, on the same network. 4 checks since 15 January 2025: sum of 20 PFAS up to 68 ng/L, sometimes below the detection limit.

Frequently asked questions
Is tap water in Courtillers safe to drink?
All the values shown here (1 July 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “Eau d'alimentation conforme aux normes en vigueur pour l'ensemble des paramètres mesurés. Les teneurs en plomb, cuivre et nickel ne valent que pour le point d'utilisation où elles ont été mesurées. En effet, 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. En cas de valeur proche ou supérieure à une des limites, il est conseillé d'assurer un écoulement d'eau, au robinet concerné, avant utilisation, voir de procéder à un changement de robinetterie.”
How high are PFAS levels in Courtillers's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 68 ng/L. The EU limit is 100 ng/L, so this water is at 68 % of the limit. (below the EU limit)
Does the water in Courtillers also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 7.6 ng/L. That is 1.9 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 Courtillers'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 Courtillers?
The water hardness in Courtillers is 17.8 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 21 September 2026.
