PFAS in Beuzec-Cap-Sizun's tap water: 34.1 ng/L, 68.2x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
68.2× 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 Beuzec-Cap-Sizun, the 4 most closely watched PFAS (PFAS-4) add up to 34.1 ng/L (0.0341 µg/L) at the latest PFAS check on 17 June 2026. That's 68.2 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 35.3 ng/L (0.0353 µg/L), below the EU legal limit (100 ng/L). 2 checks since 13 April 2026: PFAS-4 up to 34.1 ng/L, sometimes below the detection limit.

PFAS over time in Beuzec-Cap-Sizun
3 PFAS checks since 12 March 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Beuzec-Cap-Sizun.
“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 |

Frequently asked questions
Is tap water in Beuzec-Cap-Sizun safe to drink?
Yes. At the check on 17 June 2026, the tap water in Beuzec-Cap-Sizun was within every limit tested. “Eau d’alimentation conforme aux limites de qualité, mais ne satisfaisant pas totalement aux références de qualité, en raison d’un indice relatif à l’équilibre calco‑carbonique supérieur à 2. Cet indice traduit le caractère peu minéralisé de l’eau, susceptible d’interagir avec les matériaux constitutifs des canalisations, sans incidence directe sur la santé du consommateur. Une optimisation du traitement de neutralisation-minéralisation à l'unité de production est nécessaire. A noter que la valeur indicative de 0,9µg/L applicable aux métabolites de pesticides non pertinents est dépassée pour l'ESA métolachlore.”
How high are PFAS levels in Beuzec-Cap-Sizun's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 35.3 ng/L. The EU limit is 100 ng/L, so this water is at 35 % of the limit. (below the EU limit)
Does the water in Beuzec-Cap-Sizun also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 34.1 ng/L. That is 8.5 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 Beuzec-Cap-Sizun's tap water?
Too few quantified checks to say (1 since 12 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 Beuzec-Cap-Sizun?
The water hardness in Beuzec-Cap-Sizun is 9.6 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
