PFAS in drinking water

No PFAS detected

Amount found in the water < 4 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, none found
Our health benchmark 0.5 ng/L

The lab sees nothing below 4 ng/L, 8 times our benchmark of 0.5 ng/L. Water above our benchmark would pass this check unnoticed.

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 Saint-Martin-aux-Champs, on the same distribution network as Togny-aux-Bœufs (CCMC ECURY-MAIRY-COUPETZ). 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.

The lab detects each of the four substances from 1 ng/L upward. None reached that limit, so their total is below 4 ng/L rather than zero.

In Togny-aux-Bœufs, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 1 June 2026. The total is below 4 ng/L, the sum of the detection limits and 8 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,029 µg/L, below the EU legal limit (100 ng/L). Sampled in Saint-Martin-aux-Champs, on the same network. 2 checks since 26 May 2025, sum of 20 PFAS always below the detection limit (29 ng/L).

PFAS over time in Togny-aux-Bœufs

2 PFAS checks since 26 May 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Togny-aux-Bœufs.

“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Frequently asked questions

Is tap water in Togny-aux-Bœufs safe to drink?

Yes. At the check on 1 June 2026, the tap water in Togny-aux-Bœufs was within every limit tested. Outside a reference value: Coliform bacteria 1 n/(100mL) on 10 March 2026 (reference ≤ 0 mL)). These are indicator parameters with reference values, not legal limits. “Le résultat des prélèvements effectués révèle une qualité d'EAU CONFORME en ce qui concerne les paramètres microbiologiques contrôlés. Néanmoins, des bactéries coliformes ont été détectées. Ces germes ne sont pas préjudiciables à la santé publique mais révèlent la nécessité de vérifier les installations de production, de traitement et de distribution de l'eau. L'EAU ET LES INSTALLATIONS SONT A SURVEILLER. Maintenir un résiduel en chlore de 0,3 mg/l sur l'ensemble du réseau.”

How high are PFAS levels in Togny-aux-Bœufs's drinking water?

At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 29 ng/L. The EU limit is 100 ng/L, so this water is under 29 % of the limit. (below the EU limit)

Does the water in Togny-aux-Bœufs also meet the strictest limits in Europe?

As far as this check can tell, yes. None of the four compounds was quantified, so their total is below 4 ng/L, the sum of the laboratory's detection limits, and under Sweden's legal limit of 4 ng/L in force since 2026.

Are PFAS levels rising in Togny-aux-Bœufs'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 Togny-aux-Bœufs?

The water hardness in Togny-aux-Bœufs is 21.6 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
