PFAS in Plouasne's tap water: 1.62 ng/L, 3.2x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
3.2× 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 Plouasne, the 4 most closely watched PFAS (PFAS-4) add up to 1.62 ng/L (0.0016 µg/L) at the latest PFAS check on 11 December 2025. That's 3.2 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 2.92 ng/L (0.0029 µg/L), below the EU legal limit (100 ng/L). 5 checks since 23 April 2025: PFAS-4 up to 1.8 ng/L, sometimes below the detection limit, averaging at least 0.68 ng/L over 12 months (non-detects as 0).

Frequently asked questions
Is tap water in Plouasne safe to drink?
All the values shown here (22 July 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés. Cependant, il convient de signaler la présence de trace de pesticide et la mise en évidence de chlorates. La réglementation fixe une limite de qualité à 700 µg/l pour le param ètre chlorates, lorsqu'une méthode de désinfection des eaux destinées à la cons ommation humaine qui en génére est utilisée. Au delà de cette valeur, il est recommandé de ne pas consommer cette eau, une restriction d'usa ge est nécessaire. La valeur la plus faible possible de ce paramètre d oit être visée sans pour autant compromettre la désinfection. Compte tenu de la teneur mesurée en chlorates sur ce prélèvement, un suivi re nforcé sera mis en place sur ce paramètre.”
How high are PFAS levels in Plouasne's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 2.92 ng/L. The EU limit is 100 ng/L, so this water is at 3 % of the limit. (below the EU limit)
Does the water in Plouasne 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 1.62 ng/L stays below.
Are PFAS levels rising in Plouasne's tap water?
Too few quantified checks to say (2 since 19 March 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values. These history statistics use laboratory-published sums only.
How hard is the water in Plouasne?
The water hardness in Plouasne is 15 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
