PFAS in Erdre-en-Anjou's tap water: 4.3 ng/L, 8.6x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
8.6× 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 Saint-Georges-sur-Loire, on the same distribution network as Erdre-en-Anjou (SAINT GEORGES - BECON). 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 Erdre-en-Anjou, the 4 most closely watched PFAS (PFAS-4) add up to 4.3 ng/L (0.0043 µg/L) at the latest PFAS check on 22 January 2026. That's 8.6 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 13 ng/L (0.013 µg/L), below the EU legal limit (100 ng/L). Sampled in Saint-Georges-sur-Loire, on the same network. 2 checks since 1 April 2025: sum of 20 PFAS up to 13 ng/L, sometimes below the detection limit.

Frequently asked questions
Is tap water in Erdre-en-Anjou safe to drink?
Yes. At the check on 18 May 2026, the tap water in Erdre-en-Anjou 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 Erdre-en-Anjou's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 13 ng/L. The EU limit is 100 ng/L, so this water is at 13 % of the limit. (below the EU limit)
Does the water in Erdre-en-Anjou also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 4.3 ng/L. That is 1.08 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 Erdre-en-Anjou'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 Erdre-en-Anjou?
The water hardness in Erdre-en-Anjou is 16.7 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
