PFAS in Rochecorbon's tap water: 6.7 ng/L, 13.4x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
13.4× 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 Parçay-Meslay, on the same distribution network as Rochecorbon (PARCAY MESLAY(ROCHECORBON)). 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 Rochecorbon, the 4 most closely watched PFAS (PFAS-4) add up to 6.7 ng/L (0.0067 µg/L) at the latest PFAS check on 27 July 2026. That's 13.4 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 17 ng/L (0.017 µg/L), below the EU legal limit (100 ng/L). Sampled in Parçay-Meslay, on the same network. 5 checks since 27 May 2025: sum of 20 PFAS up to 19 ng/L, sometimes below the detection limit.

PFAS over time in Rochecorbon
5 PFAS checks since 27 May 2025, from the published measurements.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Frequently asked questions
Is tap water in Rochecorbon safe to drink?
Yes. At the check on 27 July 2026, the tap water in Rochecorbon was within every limit tested. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité pour la température. Une température élevée de l’eau stimule la croissance des micro-organismes et peut accroître les problèmes liés au goût, à l’odeur, à la coloration et à la corrosion.”
How high are PFAS levels in Rochecorbon's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 17 ng/L. The EU limit is 100 ng/L, so this water is at 17 % of the limit. (below the EU limit)
Does the water in Rochecorbon also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 6.7 ng/L. That is 1.68 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 Rochecorbon'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 Rochecorbon?
The water hardness in Rochecorbon is 20.2 °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.
