PFAS in drinking water
118.6× 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.
Sample taken in Yvias, on the same distribution network as Ploubazlanec (COMMUNAUTE DE COM. PAIMPOL-GOELO). The health authority samples one tap per network; a network carries the same treated water everywhere.
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 Ploubazlanec, the 4 most closely watched PFAS (PFAS-4) add up to 59.3 ng/L (0.0593 µg/L) at the latest PFAS check on 4 March 2026. That's 118.6 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 64.8 ng/L (0.0648 µg/L), below the EU legal limit (100 ng/L). Sampled in Yvias, on the same network. 3 checks since 20 February 2025: PFAS-4 up to 59.3 ng/L, sometimes below the detection limit.

Frequently asked questions
Is tap water in Ploubazlanec safe to drink?
Yes. At the check on 4 March 2026, the tap water in Ploubazlanec 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 Ploubazlanec's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 64.8 ng/L. The EU limit is 100 ng/L, so this water is at 65 % of the limit. (below the EU limit)
Does the water in Ploubazlanec also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 59.3 ng/L. That is 14.8 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 Ploubazlanec's tap water?
Too few quantified checks to say (1 since 20 February 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.
How hard is the water in Ploubazlanec?
The water hardness in Ploubazlanec is 15 °f (medium). 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 12 September 2026.
Same water network
Same distribution network as Ploubazlanec, so in principle the same water.
