PFAS in drinking water

No 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, none found
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.

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.

In Montagny-Sainte-Félicité, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 7 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: <0,029 µg/L, below the EU legal limit (100 ng/L). 2 checks since 10 December 2025, PFAS-4 always below the detection limit (4 ng/L).

Frequently asked questions

Is tap water in Montagny-Sainte-Félicité safe to drink?

At the latest check, the water was over at least one limit. “Eau d'alimentation non-conforme aux limites de qualité en vigueur pour les paramètres desphényl-chloridazone, méthyl-desphényl-chloridazone, chlorothalonil R417888, total pesticides, présentant des dépassements de la valeur indicative de 0,9 µg/L pour le chlorothalonil R471811 et non conforme à la référence de qualité équilibre calcocarbonique, l'eau étant notée comme incrustante. Toutefois, cette eau est propre à la consommation humaine car la concentration des pesticides concernés reste inférieure aux valeurs sanitaires. Un contrôle renforcé est mis en place.”

How high are PFAS levels in Montagny-Sainte-Félicité's drinking water?

At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 29 ng/L. The EU limit is 100 ng/L, so this water is under 29 % of the limit. (below the EU limit)

Does the water in Montagny-Sainte-Félicité 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 Montagny-Sainte-Félicité's tap water?

Too few quantified checks to say (0 since 27 September 2024). pfasnearme adds each new publication weekly; a trend needs at least three quantified values. These history statistics use laboratory-published sums only.

How hard is the water in Montagny-Sainte-Félicité?

The water hardness in Montagny-Sainte-Félicité is 50.4 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
