PFAS in the tap water of Tilly (Eure): 1.1 ng/L, 2.2x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
2.2× 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.
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 Tilly, the 4 most closely watched PFAS (PFAS-4) add up to 1.1 ng/L (0.0011 µg/L) at the latest PFAS check on 18 February 2025. That's 2.2 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 1.1 ng/L (0.0011 µg/L), below the EU legal limit (100 ng/L).

Frequently asked questions
Is tap water in Tilly safe to drink?
Yes. At the check on 7 July 2026, the tap water in Tilly 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 Tilly's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 1.1 ng/L. The EU limit is 100 ng/L, so this water is at 1 % of the limit. (below the EU limit)
Does the water in Tilly 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 1.1 ng/L stays below.
How hard is the water in Tilly?
The water hardness in Tilly is 30.8 °f (hard). 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.
