PFAS in Aulnay-la-Rivière's tap water: under 4 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 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.

Frequently asked questions
Is tap water in Aulnay-la-Rivière safe to drink?
At the latest check, the water was over at least one limit. “Ce prélèvement a mis en évidence une concentration en nitrates non conforme aux exigences réglementaires, qui nécessite que vous preniez des mesures correctives afin de rétablir la qualité de l'eau et m'en informiez ainsi que les consommateurs (art. R.1321-27 à 30 du code de la santé publique). Ce prélèvement a également mis en évidence une teneur en perchlorates supérieure à 15 µg/l. Je vous demande d'informer la population d'une recommandation de non-consommation de l'eau pour les femmes enceintes et allaitantes et les nourrissons de moins de 6 mois. Les prochains travaux prévus permettront de remédier à ces anomalies. Les autres paramètres mesurés sont conformes aux exigences de qualité malgré des traces de pesticides.”
How high are PFAS levels in Aulnay-la-Rivière's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 4 ng/L. The EU limit is 100 ng/L, so this water is at 4 % of the limit. (below the EU limit)
Does the water in Aulnay-la-Rivière 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 Aulnay-la-Rivière?
The water hardness in Aulnay-la-Rivière is 30.3 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
