PFAS in drinking water

None of the 4 most harmful 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, 2 ng/L found in total
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-Éloy-les-Mines, on the same distribution network as Teilhède (SIAEP SIOULE ET MORGE). 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 Teilhède, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 8 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: 2 ng/L (0.002 µg/L), below the EU legal limit (100 ng/L). Sampled in Saint-Éloy-les-Mines, on the same network. 5 checks since 25 June 2025, PFAS-4 always below the detection limit (4 ng/L).

PFAS over time in Teilhède

5 PFAS checks since 25 June 2025, values as published. Samples from 2 communes on the same network: it's the same water, so each one applies to Teilhède.

Frequently asked questions

Is tap water in Teilhède safe to drink?

Yes. At the check on 8 June 2026, the tap water in Teilhède 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 Teilhède's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 2 ng/L. The EU limit is 100 ng/L, so this water is at 2 % of the limit. (below the EU limit)

Does the water in Teilhède 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 Teilhède's tap water?

No. Since 25 June 2025, 5 checks have been published and the PFAS-4 sum stayed below the laboratory's detection limit (4 ng/L) every time.

How hard is the water in Teilhède?

No hardness value is available for Teilhède in this source.

Where does this data come from?

All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 21 September 2026.

Same water network

Same distribution network as Teilhède, so in principle the same water.
