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 Orgelet, on the same distribution network as La Tour-du-Meix (LA TOUR DU MEIX). 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.

None found. The lab sees nothing below 4 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In La Tour-du-Meix, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 28 April 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 Orgelet, on the same network. 3 checks since 8 October 2025, PFAS-4 always below the detection limit (4 ng/L).

PFAS over time in La Tour-du-Meix

4 PFAS checks since 10 March 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to La Tour-du-Meix. Samples come from 2 distribution networks. The trend refers to the network “SIAEP REGION DE VOUGLANS”.

“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 La Tour-du-Meix safe to drink?

Yes. At the check on 8 June 2026, the tap water in La Tour-du-Meix 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 La Tour-du-Meix'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 La Tour-du-Meix 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 La Tour-du-Meix's tap water?

No. Since 10 March 2025, 3 checks have been published and the PFAS-4 sum stayed below the laboratory's detection limit (4 ng/L) every time. These history statistics use laboratory-published sums only.

How hard is the water in La Tour-du-Meix?

The water hardness in La Tour-du-Meix is 26.5 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
