PFAS in Chisseaux's tap water: 0.7 ng/L, 1.4x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
1.4× 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 Civray-de-Touraine, on the same distribution network as Chisseaux (CIVRAY DE TOURAINE). 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).
More PFAS than in 82% of the cities we track

In Chisseaux, the 4 most closely watched PFAS (PFAS-4) add up to 0.7 ng/L (0.0007 µg/L) at the latest PFAS check on 16 December 2025. That's 1.4 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 0.7 ng/L (0.0007 µg/L), below the EU legal limit (100 ng/L). Sampled in Civray-de-Touraine, on the same network. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions
Is tap water in Chisseaux safe to drink?
Yes. At the check on 29 April 2026, the tap water in Chisseaux was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”
How high are PFAS levels in Chisseaux's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 0.7 ng/L. The EU limit is 100 ng/L, so this water is at 0.7 % of the limit. (below the EU limit)
Does the water in Chisseaux also meet the strictest limits in Europe?
Yes. Even against Europe's strictest legal limit, Sweden's 4 ng/L in force since 2026, the measured value of 0.7 ng/L stays below.
How hard is the water in Chisseaux?
The water hardness in Chisseaux is 15.3 °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 12 September 2026.
