PFAS in Saint-Valentin's tap water: 7 ng/L, 14x our 0.5 ng/L benchmark

Last PFAS check: · Source: Hub'eau

PFAS in drinking water

14× above our health benchmark

Amount found in the water 7 ng/L 0.007 µg/L · the 4 most harmful PFAS (PFAS-4)
Our health benchmark 0.5 ng/L

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 Brion, on the same distribution network as Saint-Valentin (BRION). 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

In Saint-Valentin, the 4 most closely watched PFAS (PFAS-4) add up to 7 ng/L (0.007 µg/L) at the latest PFAS check on 23 September 2025. That's 14 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 15 ng/L (0.015 µg/L), below the EU legal limit (100 ng/L). Sampled in Brion, on the same network. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions

Is tap water in Saint-Valentin safe to drink?

Yes. At the check on 3 February 2026, the tap water in Saint-Valentin was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”

How high are PFAS levels in Saint-Valentin's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 15 ng/L. The EU limit is 100 ng/L, so this water is at 15 % of the limit. (below the EU limit)

Does the water in Saint-Valentin also meet the strictest limits in Europe?

No. The four most harmful PFAS add up to 7 ng/L. That is 1.75 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).

How hard is the water in Saint-Valentin?

The water hardness in Saint-Valentin is 24.4 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?

All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 12 September 2026.

Same water network

Same distribution network as Saint-Valentin, so in principle the same water.
