PFAS in drinking water

None of the 4 most harmful PFAS detected

Amount found in the water < 4 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, 3 ng/L found in total
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 Montsauche-les-Settons, on the same distribution network as Alligny-en-Morvan (LA FAYE). 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 Alligny-en-Morvan, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 8 April 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: 3 ng/L (0.003 µg/L), below the EU legal limit (100 ng/L). Sampled in Montsauche-les-Settons, on the same network. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions

Is tap water in Alligny-en-Morvan safe to drink?

Yes. At the check on 26 May 2026, the tap water in Alligny-en-Morvan was within every limit tested. Outside a reference value: Electrical conductivity 77 µS/cm on 26 May 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “La teneur en chlore est insuffisante pour garantir une désinfection ef ficace de l’eau distribuée sur l’ensemble du réseau. Il est recommandé de maintenir au moins 0,1 mg/L en tout point du réseau. Les autres paramètres mesurés répondent aux normes de potabilité, excepté la cond uctivité.”

How high are PFAS levels in Alligny-en-Morvan's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 3 ng/L. The EU limit is 100 ng/L, so this water is at 3 % of the limit. (below the EU limit)

Does the water in Alligny-en-Morvan 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.

How hard is the water in Alligny-en-Morvan?

The water hardness in Alligny-en-Morvan is 35.4 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
