PFAS in Dinard's tap water: 1.57 ng/L, 3.1x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
3.1× 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 Dinard, the 4 most closely watched PFAS (PFAS-4) add up to 1.57 ng/L (0.0016 µg/L) at the latest PFAS check on 22 June 2026. That's 3.1 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 12.4 ng/L (0.0124 µg/L), below the EU legal limit (100 ng/L). 4 checks since 22 April 2025: PFAS-4 from 1.57 ng/L to 2.54 ng/L, averaging 1.94 ng/L over 12 months. No clear trend.

PFAS over time in Dinard
5 PFAS checks since 18 February 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Dinard.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.
| Date | PFAS-4 | Sum of 20 PFAS | Sampled at |
|---|---|---|---|
| 1.57 ng/L | 12.4 ng/L | Dinard | |
| 1.75 ng/L | 14.41 ng/L | Pleurtuit | |
| 2.51 ng/L | 21.8 ng/L | Pleurtuit | |
| 2.54 ng/L | 14.51 ng/L | Pleurtuit | |
| < 3.4 ng/L · calculated | 6.95 ng/L | Pleurtuit |
Calculated values: “<” is an upper bound from published thresholds, “≥” a lower bound, “–” means no published sum or complete measurement. How to read a PFAS result

Frequently asked questions
Is tap water in Dinard safe to drink?
Yes. At the check on 28 July 2026, the tap water in Dinard 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 Dinard's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 12.4 ng/L. The EU limit is 100 ng/L, so this water is at 12 % of the limit. (below the EU limit)
Does the water in Dinard 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 1.57 ng/L stays below.
Are PFAS levels rising in Dinard's tap water?
No clear trend. Since 18 February 2025, 4 checks have been published; on the main network the PFAS-4 sum ranged between 1.57 ng/L and 2.54 ng/L (4 quantified values), at times below the detection limit. pfasnearme only reports a trend from a change of at least 25 % and 1 ng/L. These history statistics use laboratory-published sums only.
How hard is the water in Dinard?
The water hardness in Dinard is 17.4 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
