PFAS in Bazouges-la-Pérouse's tap water: 4.65 ng/L, 9.3x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
9.3× 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 Bazouges-la-Pérouse, the 4 most closely watched PFAS (PFAS-4) add up to 4.65 ng/L (0.0047 µg/L) at the latest PFAS check on 8 July 2026. That's 9.3 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 14.1 ng/L (0.0141 µg/L), below the EU legal limit (100 ng/L). 3 checks since 15 October 2025: PFAS-4 from 2.6 ng/L to 6.56 ng/L, averaging 4.6 ng/L over 12 months. Falling on the main network. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions
Is tap water in Bazouges-la-Pérouse safe to drink?
Yes. At the check on 8 July 2026, the tap water in Bazouges-la-Pérouse was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés. Les analyses réalisées ont cependan t mis en évidence la présence importante de chlorates. La réglementati on fixe une limite de qualité à 700 µg/l pour ce paramètre, lorsqu'une méthode de désinfection des eaux destinées à la consommation humaine qui en génére est utilisée. Au delà de cette valeur, il est recommand é de ne pas consommer cette eau, une restriction d'usage est nécessair e. La valeur la plus faible possible de ce paramètre doit être visée s ans pour autant compromettre la désinfection. Compte tenu de la teneu r mesurée en chlorates sur ce prélèvement, un suivi renforcé sera mis en place sur ce paramètre. Par ailleurs, des traces de pesticides (don t l'ethephon, régulateur de croissance) peut-être observée dans le cad re de ce contrôle.”
How high are PFAS levels in Bazouges-la-Pérouse's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 14.1 ng/L. The EU limit is 100 ng/L, so this water is at 14 % of the limit. (below the EU limit)
Does the water in Bazouges-la-Pérouse also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 4.65 ng/L. That is 1.16 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 Bazouges-la-Pérouse's tap water?
No, they are falling. On the main network, the PFAS-4 sum went from 6.56 ng/L (15 October 2025) to 4.65 ng/L (8 July 2026) across 3 quantified checks. These history statistics use laboratory-published sums only.
How hard is the water in Bazouges-la-Pérouse?
The water hardness in Bazouges-la-Pérouse is 9.3 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
