PFAS in drinking water
1,178× 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.
More about this result
The US also limits PFOA and PFOS to 4 ng/L each, per substance.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

What the latest check found
At the latest check, the water was within every limit tested.
Values to watch
These results are close to their legal limit, or over it.
Outside a reference value: Coliform bacteria 6 n/(100mL) on 2 June 2026 (reference ≤ 0 mL)). These are indicator parameters with reference values, not legal limits.
| What was tested | Value | Limit | Status |
|---|---|---|---|
| Nitrate | 30.8 mg/L | ≤ 50 mg/L | within the limit |
| Coliform bacteria | 6 n/(100mL) | ≤ 0 mL) | above the reference value |

Frequently asked questions
Is tap water in Villy safe to drink?
At the latest check, the water was over at least one limit. “La référence de qualité(norme non impérative) relative à la numération des bactéries coliformes n'est pas satisfaite. Une vérification des installations peut s'avérer nécessaire, notamment le traitement de désinfection s'il existe. Depuis le 10/07/2025, la consommation de l'eau est interdite par arrêté préfectoral à des fins de boisson en raison d e la teneur de la somme des 20 PFAS supérieure à la limite de qualité. Les autres usages restent autorisés.”
How high are PFAS levels in Villy's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 2,099 ng/L. The EU limit is 100 ng/L, so this water is at 2,099 % of the limit. (above the EU limit)
Does the water in Villy also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 589 ng/L. That is 147.3 times Sweden's legal limit of 4 ng/L, in force since 2026. Germany will set a similar one in 2028. The sum of 20 PFAS is 2,099 ng/L, above the EU legal limit of 100 ng/L.
Are PFAS levels rising in Villy'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 Villy?
The water hardness in Villy is 23.4 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
