PFAS in Maizières-la-Grande-Paroisse's tap water: under 8 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
None of the 4 most harmful PFAS detected
The lab sees nothing below 8 ng/L, 16 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 2 ng/L upward. None reached that limit, so their total is below 8 ng/L rather than zero.

Frequently asked questions
Is tap water in Maizières-la-Grande-Paroisse safe to drink?
Yes. At the check on 22 July 2026, the tap water in Maizières-la-Grande-Paroisse was within every limit tested. “L'eau est conforme aux limites de qualité bactériologique mais non conforme aux références de qualité bactériologique définies par l'arrêté du 11 janvier 2007 de par la présence en excès de bactéries du type aérobies revivifiables à 36°, sans présenter toutefois un risque sanitaire pour le consommateur. Cette eau est ègalememnt non conforme aux références de qualité chimiq ue. Cette non-conformité porte sur le paramètre carbone organique total sans pré senter toutefois un risque sanitaire pour le consommateur. Ce dépassement peut provenir d'un nettoyage tardif de votre réservoir. Il convient de prendre toutes les mesures nécessaires au rétablissement de la qualité de l'eau.”
How high are PFAS levels in Maizières-la-Grande-Paroisse'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 Maizières-la-Grande-Paroisse also meet the strictest limits in Europe?
The check cannot say. None of the four compounds was quantified, but the laboratory's detection limits add up to 8 ng/L, above Sweden's legal limit of 4 ng/L in force since 2026, so a value between the two would go unnoticed.
How hard is the water in Maizières-la-Grande-Paroisse?
The water hardness in Maizières-la-Grande-Paroisse is 25.2 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
