PFAS in drinking water

36× above our health benchmark

Amount found in the water 18 ng/L 0.018 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 Bogy, on the same distribution network as Colombier-le-Cardinal (SYND ANN. SERR. UDI TERRES CARREES). 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.

One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

In Colombier-le-Cardinal, the 4 most closely watched PFAS (PFAS-4) add up to 18 ng/L (0.018 µg/L) at the latest PFAS check on 7 April 2026. That's 36 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 47 ng/L (0.047 µg/L), below the EU legal limit (100 ng/L). Sampled in Bogy, on the same network. 6 checks since 19 August 2025: PFAS-4 from 18 ng/L to 26 ng/L, averaging 23.5 ng/L over 12 months. Falling on the main network.

Frequently asked questions

Is tap water in Colombier-le-Cardinal safe to drink?

Yes. At the check on 23 June 2026, the tap water in Colombier-le-Cardinal 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 Colombier-le-Cardinal's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 47 ng/L. The EU limit is 100 ng/L, so this water is at 47 % of the limit. (below the EU limit)

Does the water in Colombier-le-Cardinal also meet the strictest limits in Europe?

No. The four most harmful PFAS add up to 18 ng/L. That is 4.5 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 Colombier-le-Cardinal's tap water?

No, they are falling. On the main network, the PFAS-4 sum went from 24 ng/L (19 August 2025) to 18 ng/L (7 April 2026) across 6 quantified checks. These history statistics use laboratory-published sums only.

How hard is the water in Colombier-le-Cardinal?

The water hardness in Colombier-le-Cardinal is 26.8 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
