PFAS in drinking water

No PFAS detected

Our health benchmark 0.5 ng/L

The lab sees nothing below 4 ng/L, 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 Hambye, on the same distribution network as Moyon Villages (LA SEROUDIERE). 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 1 ng/L upward. None reached that limit, so their total is below 4 ng/L rather than zero.

None found. The lab sees nothing below 4 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Moyon Villages, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 16 July 2026. The total is below 4 ng/L, the sum of the detection limits and 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 Hambye, on the same network. 7 checks since 3 March 2025: sum of 20 PFAS up to 6.7 ng/L, sometimes below the detection limit.

PFAS over time in Moyon Villages

7 PFAS checks since 3 March 2025, from the published measurements. Samples from 3 communes on the same network: it's the same water, so each one applies to Moyon Villages. Samples come from 2 distribution networks. The trend refers to the network “CHAPELLE S/VIRE”.

“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Frequently asked questions

Is tap water in Moyon Villages safe to drink?

Yes. At the check on 16 July 2026, the tap water in Moyon Villages was within every limit tested. “Eau d'alimentation conforme aux limites et références de qualité pour l'ensemble des paramètres mesurés.”

How high are PFAS levels in Moyon Villages'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 Moyon Villages 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 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 Moyon Villages'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 Moyon Villages?

The water hardness in Moyon Villages is 16.8 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?

All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 21 September 2026.
