PFAS in Vallerois-Lorioz's tap water: 3 ng/L, 6x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
6× 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 Vellefaux, on the same distribution network as Vallerois-Lorioz (SIAEP DE VELLEFAUX). 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 88% of the cities we track

In Vallerois-Lorioz, the 4 most closely watched PFAS (PFAS-4) add up to 3 ng/L (0.003 µg/L) at the latest PFAS check on 19 May 2026. That's 6 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 9 ng/L (0.009 µg/L), below the EU legal limit (100 ng/L). Sampled in Vellefaux, on the same network. 2 checks since 12 November 2025: PFAS-4 from 3 ng/L to 4 ng/L. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions
Is tap water in Vallerois-Lorioz safe to drink?
Yes. At the check on 15 July 2026, the tap water in Vallerois-Lorioz was within every limit tested. “Le taux de désinfectant trop élevé donne à l'eau un goût et des odeurs et peut conduire à la formation de sous produits indésirables (la valeur recommandée en désinfectant est à 0,1 mg/l). Néanmoins, l'eau peut être consommée.”
How high are PFAS levels in Vallerois-Lorioz's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 9 ng/L. The EU limit is 100 ng/L, so this water is at 9 % of the limit. (below the EU limit)
Does the water in Vallerois-Lorioz also meet the strictest limits in Europe?
Yes. Even against Europe's strictest legal limit, Sweden's 4 ng/L in force since 2026, the measured value of 3 ng/L stays below.
Are PFAS levels rising in Vallerois-Lorioz's tap water?
Too few quantified checks to say (2 since 12 November 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.
How hard is the water in Vallerois-Lorioz?
The water hardness in Vallerois-Lorioz is 33.4 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
