PFAS in Mézidon Vallée d'Auge's tap water: under 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 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 Mézidon Vallée d'Auge, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 29 June 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). 17 checks since 15 January 2025: sum of 20 PFAS up to 1.2 ng/L, sometimes below the detection limit.

Frequently asked questions
Is tap water in Mézidon Vallée d'Auge safe to drink?
At the latest check, the water was over at least one limit. “Les teneurs en chloridazone méthyl desphényl et chlorothalonil R417888 (produit de dégradation de pesticides) restent inférieures aux valeurs limites fixées dans l'arrêté préfectoral de dérogation à la limite de qualité. Un programme d'amél ioration de la qualité des eaux porté par la collectivité est en cours , avec un suivi régulier des teneurs. A noter également que la somme des pesticides dépasse la limite de qua lité de 0,5µg/L et que la valeur indicative définie pour le chlorothalonil R471811 n'est pas satisfaite. Un suivi renforcé est mis en place pour suivre l'évolution de ce paramètre. Les autres paramètres sont conformes. L'eau peut être consommée sans restriction d'usage.”
How high are PFAS levels in Mézidon Vallée d'Auge'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 Mézidon Vallée d'Auge 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 Mézidon Vallée d'Auge'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 Mézidon Vallée d'Auge?
The water hardness in Mézidon Vallée d'Auge is 32.2 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
