PFAS in Moussé's tap water: under 3.4 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
No PFAS detected
The lab sees nothing below 3.4 ng/L, 6.8 times our benchmark of 0.5 ng/L. Water above our benchmark would pass this check unnoticed.
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 Moutiers, on the same distribution network as Moussé (EAU PORTES BRETAGNE_BILLERIE_GUERCHE). 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.
The lab detects each of the four substances from 0.4 to 1 ng/L upward. None reached that limit, so their total is below 3.4 ng/L rather than zero.

None found. The lab sees nothing below 3.4 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Moussé, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 11 March 2026. The total is below 3.4 ng/L, the sum of the detection limits and 6.8 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <SEUIL µg/L, below the EU legal limit (100 ng/L). Sampled in Moutiers, on the same network. 3 checks since 30 July 2025, PFAS-4 always below the detection limit. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).
Details and sources
PFAS over time in Moussé
4 PFAS checks since 25 March 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Moussé.
“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 |
|---|---|---|---|
| < detection limit | < detection limit | Moutiers | |
| < detection limit | < detection limit | Vitré | |
| < detection limit | < detection limit | Vitré | |
| < 3.4 ng/L · calculated | < detection limit | Vitré |
Calculated values: “<” is an upper bound from published thresholds, “≥” a lower bound, “–” means no published sum or complete measurement. How to read a PFAS result

Frequently asked questions
Is tap water in Moussé safe to drink?
Yes. At the check on 28 May 2026, the tap water in Moussé was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés. A noter cependant en ce point d'échantillonnage, la présence d'une flore revivifiable légèrement élevée.”
How high are PFAS levels in Moussé's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at –. The EU limit is 100 ng/L, so this water is at – of the limit. (below the EU limit)
Does the water in Moussé also meet the strictest limits in Europe?
As far as this check can tell, yes. None of the four compounds was quantified, so their total is below 3.4 ng/L, the sum of the laboratory's detection limits, and under Sweden's legal limit of 4 ng/L in force since 2026.
Are PFAS levels rising in Moussé's tap water?
No. Since 25 March 2025, 3 checks have been published and the PFAS-4 sum stayed below the laboratory's detection limit every time. These history statistics use laboratory-published sums only.
How hard is the water in Moussé?
The water hardness in Moussé is 16.8 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
