PFAS in Sin-le-Noble's tap water: 21 ng/L, 42x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
42× 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 Sin-le-Noble, the 4 most closely watched PFAS (PFAS-4) add up to 21 ng/L (0.021 µg/L) at the latest PFAS check on 22 April 2026. That's 42 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 32 ng/L (0.032 µg/L), below the EU legal limit (100 ng/L). 4 checks since 18 March 2026: PFAS-4 up to 28 ng/L, sometimes below the detection limit, averaging at least 12.25 ng/L over 12 months (non-detects as 0).

PFAS over time in Sin-le-Noble
4 PFAS checks since 18 March 2026, values as published. Samples from 2 communes on the same network: it's the same water, so each one applies to Sin-le-Noble.
| Date | PFAS-4 | Sum of 20 PFAS | Sampled at |
|---|---|---|---|
| 21 ng/L | 32 ng/L | Sin-le-Noble | |
| 28 ng/L | – | Sin-le-Noble | |
| < 4 ng/L | – | Sin-le-Noble | |
| < 1 ng/L | < 1 ng/L | Dechy |
“<” means not detected, the figure being the detection limit. “–” means not published. Labs have only reported the PFAS-4 sum (SANDRE code 9268) since autumn 2025. How to read a PFAS result

Frequently asked questions
Is tap water in Sin-le-Noble safe to drink?
Yes. At the check on 20 July 2026, the tap water in Sin-le-Noble 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 Sin-le-Noble's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 32 ng/L. The EU limit is 100 ng/L, so this water is at 32 % of the limit. (below the EU limit)
Does the water in Sin-le-Noble also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 21 ng/L. That is 5.3 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 Sin-le-Noble's tap water?
Too few quantified checks to say (2 since 18 March 2026). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.
How hard is the water in Sin-le-Noble?
The water hardness in Sin-le-Noble is 42 °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.
