Last PFAS check: · Source: Hub'eau
PFAS in drinking water
12.8× 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 Villez-sur-le-Neubourg, on the same distribution network as Crosville-la-Vieille (NEUBOURG). 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).
More PFAS than in 94% of the cities we track

PFAS over time in Crosville-la-Vieille
4 PFAS checks since 22 January 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Crosville-la-Vieille.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Frequently asked questions
Is tap water in Crosville-la-Vieille safe to drink?
At the latest check, the water was over at least one limit. “Eau d'alimentation non conforme à la limite de qualité fixée pour les nitrates : il est recommandé aux femmes enceintes et nourrissons de ne pas consommer cette eau. Les autres paramètres mesurés sont conformes aux exigences de qualité en vigueur. La collectivité bénéficie d'une dérogation préfectorale l’autorisant à distribuer une eau destinée à la consommation humaine dépassant la limite de qualité de 50 mg/l pour les nitrates pendant la durée des travaux nécessaires au retour à la conformité.”
How high are PFAS levels in Crosville-la-Vieille's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 10.3 ng/L. The EU limit is 100 ng/L, so this water is at 10 % of the limit. (below the EU limit)
Does the water in Crosville-la-Vieille also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 6.4 ng/L. That is 1.6 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 Crosville-la-Vieille'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.
