PFAS in drinking water

12× above our health benchmark

Amount found in the water 6 ng/L 0.006 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.

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 Annet-sur-Marne, the 4 most closely watched PFAS (PFAS-4) add up to 6 ng/L (0.006 µg/L) at the latest PFAS check on 8 July 2026. That's 12 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 25 ng/L (0.025 µg/L), below the EU legal limit (100 ng/L). 21 checks since 14 January 2026: PFAS-4 from 1 ng/L to 6 ng/L, averaging 2.83 ng/L over 12 months.

Frequently asked questions

Is tap water in Annet-sur-Marne safe to drink?

At the latest check, the water was over at least one limit. “Eau d'alimentation non-conforme aux limites de qualité pour le paramètre bromates. Un recontrôle datant du 28/07/2026 a montré un retour à la normale quant à la qualité de l'eau distribuée, vis-à-vis de ce paramètre.”

How high are PFAS levels in Annet-sur-Marne's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 25 ng/L. The EU limit is 100 ng/L, so this water is at 25 % of the limit. (below the EU limit)

Does the water in Annet-sur-Marne also meet the strictest limits in Europe?

No. The four most harmful PFAS add up to 6 ng/L. That is 1.5 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 Annet-sur-Marne's tap water?

Yes. On the main network, the PFAS-4 sum rose from 2 ng/L (14 January 2026) to 5 ng/L (8 July 2026) across 12 quantified checks. pfasnearme's benchmark is 0.5 ng/L as an annual mean. These history statistics use laboratory-published sums only.

How hard is the water in Annet-sur-Marne?

The water hardness in Annet-sur-Marne is 26.4 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
