PFAS in drinking water
12.2× 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 Guipry-Messac, on the same distribution network as Poligné (BRUYERES_FRAUX/PORT DE ROCHE_BOURG DES COMPTES). 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 Poligné, the 4 most closely watched PFAS (PFAS-4) add up to 6.1 ng/L (0.0061 µg/L) at the latest PFAS check on 19 May 2026. That's 12.2 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 7.09 ng/L (0.0071 µg/L), below the EU legal limit (100 ng/L). Sampled in Guipry-Messac, on the same network. 5 checks since 14 April 2025: PFAS-4 from 0.6 ng/L to 8.97 ng/L, averaging 7.29 ng/L over 12 months. No clear trend.

Frequently asked questions
Is tap water in Poligné safe to drink?
Yes. At the check on 19 May 2026, the tap water in Poligné was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés. Il convient cependant de noter l'absence de chlore résiduel sur ce secteur de distribution. D'une façon générale, la présence d'un résiduel de chlore est nécessaire pour se prémunir de la prolifération bactérienne dans les réseaux (objectif souhaitable : 0,1 mg/L de chlore libre). L'exploitant a été informé de cette situation dès connaissance de celle-ci par mon service, pour vérifications et actions correctives d'usage.”
How high are PFAS levels in Poligné's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 7.09 ng/L. The EU limit is 100 ng/L, so this water is at 7 % of the limit. (below the EU limit)
Does the water in Poligné also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 6.1 ng/L. That is 1.53 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 Poligné's tap water?
No clear trend. Since 14 April 2025, 5 checks have been published; on the main network the PFAS-4 sum ranged between 0.6 ng/L and 8.97 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.
How hard is the water in Poligné?
The water hardness in Poligné is 15.6 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
