PFAS in Plouyé's tap water: 7.7 ng/L, 15.4x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
15.4× 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.
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 Plouyé, the 4 most closely watched PFAS (PFAS-4) add up to 7.7 ng/L (0.0077 µg/L) at the latest PFAS check on 2 July 2026. That's 15.4 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 9.6 ng/L (0.0096 µg/L), below the EU legal limit (100 ng/L). 2 checks since 4 February 2025: sum of 20 PFAS up to 9.6 ng/L, sometimes below the detection limit.

PFAS over time in Plouyé
2 PFAS checks since 4 February 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.
| Date | PFAS-4 | Sum of 20 PFAS |
|---|---|---|
| 7.7 ng/L | 9.6 ng/L | |
| < 6 ng/L · calculated | < detection limit |
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
What the latest check found
At the latest check, the water was within every limit tested.
Values to watch
These results are close to their legal limit, or over it.
Outside a reference value: Electrical conductivity 155 µS/cm on 2 July 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits.

Frequently asked questions
Is tap water in Plouyé safe to drink?
Yes. At the check on 2 July 2026, the tap water in Plouyé was within every limit tested. Outside a reference value: Electrical conductivity 155 µS/cm on 2 July 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Eau prélevée conforme aux limites de qualité. A noter une conductivité inférieure à la valeur de référence minimale de 200µS/cm. Eau agressive. Une optimisation du traitement de neutralisation-minéralisation à l'unité de production est nécessaire.”
How high are PFAS levels in Plouyé's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 9.6 ng/L. The EU limit is 100 ng/L, so this water is at 10 % of the limit. (below the EU limit)
Does the water in Plouyé also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 7.7 ng/L. That is 1.93 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 Plouyé'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 Plouyé?
The water hardness in Plouyé is 7.3 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
