PFAS in Saint-Maurice-l'Exil's tap water: 22 ng/L, 44x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
44× 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 Le Péage-de-Roussillon, on the same distribution network as Saint-Maurice-l'Exil (PEAGE ROUSSILLON ET ST MAURICE SUD). 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 Saint-Maurice-l'Exil, the 4 most closely watched PFAS (PFAS-4) add up to 22 ng/L (0.022 µg/L) at the latest PFAS check on 19 May 2026. That's 44 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 71 ng/L (0.071 µg/L), below the EU legal limit (100 ng/L). Sampled in Le Péage-de-Roussillon, on the same network. 5 checks since 26 September 2025: PFAS-4 from 20 ng/L to 25 ng/L, averaging 22.8 ng/L over 12 months. No clear trend.

Frequently asked questions
Is tap water in Saint-Maurice-l'Exil safe to drink?
Yes. At the check on 20 May 2026, the tap water in Saint-Maurice-l'Exil 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 Saint-Maurice-l'Exil's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 71 ng/L. The EU limit is 100 ng/L, so this water is at 71 % of the limit. (below the EU limit)
Does the water in Saint-Maurice-l'Exil also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 22 ng/L. That is 5.5 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 Saint-Maurice-l'Exil's tap water?
No clear trend. Since 22 March 2023, 5 checks have been published; on the main network the PFAS-4 sum ranged between 20 ng/L and 25 ng/L (5 quantified values), at times below the detection limit. pfasnearme only reports a trend from a change of at least 25 % and 1 ng/L. These history statistics use laboratory-published sums only.
How hard is the water in Saint-Maurice-l'Exil?
The water hardness in Saint-Maurice-l'Exil is 32.4 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
