PFAS in drinking water

32× above our health benchmark

Amount found in the water 16 ng/L 0.016 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 Ferrières, on the same distribution network as Dompierre (FERRIERES). 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).

In Dompierre, the 4 most closely watched PFAS (PFAS-4) add up to 16 ng/L (0.016 µg/L) at the latest PFAS check on 9 March 2026. That's 32 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 17 ng/L (0.017 µg/L), below the EU legal limit (100 ng/L). Sampled in Ferrières, on the same network. 2 checks since 27 May 2025: sum of 20 PFAS from 7 ng/L to 17 ng/L. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions

Is tap water in Dompierre safe to drink?

At the latest check, the water was over at least one limit. “Eau d’alimentation non conforme aux limites de qualité en vigueur pour le paramètre nitrates. Il est demandé de remédier à la situation de non-conformité constatée. En attendant, cette eau est déconseillée aux populations sensibles (femmes enceintes, nourrissons) pour des usages alimentaires.”

How high are PFAS levels in Dompierre's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 17 ng/L. The EU limit is 100 ng/L, so this water is at 17 % of the limit. (below the EU limit)

Does the water in Dompierre also meet the strictest limits in Europe?

No. The four most harmful PFAS add up to 16 ng/L. That is 4 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 Dompierre'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 Dompierre?

The water hardness in Dompierre is 33.5 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?
