PFAS in drinking water

11× above our health benchmark

Amount found in the water 5.5 ng/L 0.0055 µg/L · the 4 most harmful PFAS (PFAS-4)
Our health benchmark 0.5 ng/L

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 Mauges-sur-Loire, on the same distribution network as Bégrolles-en-Mauges (MONTJEAN). 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.

One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

In Bégrolles-en-Mauges, the 4 most closely watched PFAS (PFAS-4) add up to 5.5 ng/L (0.0055 µg/L) at the latest PFAS check on 17 June 2026. That's 11 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 21 ng/L (0.021 µg/L), below the EU legal limit (100 ng/L). Sampled in Mauges-sur-Loire, on the same network. 4 checks since 24 March 2025: sum of 20 PFAS up to 21 ng/L, sometimes below the detection limit.

Frequently asked questions

Is tap water in Bégrolles-en-Mauges safe to drink?

All the values shown here (17 June 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.”

How high are PFAS levels in Bégrolles-en-Mauges's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 21 ng/L. The EU limit is 100 ng/L, so this water is at 21 % of the limit. (below the EU limit)

Does the water in Bégrolles-en-Mauges also meet the strictest limits in Europe?

No. The four most harmful PFAS add up to 5.5 ng/L. That is 1.38 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 Bégrolles-en-Mauges'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 Bégrolles-en-Mauges?

The water hardness in Bégrolles-en-Mauges is 14.7 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
