PFAS in drinking water

No PFAS detected

Amount found in the water < 6 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 6 ng/L, 12 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 Laguiole, on the same distribution network as Entraygues-sur-Truyère (VIADENE SUD - MÉLANGE AVEC LAGUIOLE). 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 1.5 ng/L upward. None reached that limit, so their total is below 6 ng/L rather than zero.

None found. The lab sees nothing below 6 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Entraygues-sur-Truyère, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 4 May 2026. The total is below 6 ng/L, the sum of the detection limits and 12 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <SEUIL µg/L, below the EU legal limit (100 ng/L). Sampled in Laguiole, on the same network. 2 checks since 4 May 2026, PFAS-4 always below the detection limit. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

PFAS over time in Entraygues-sur-Truyère

3 PFAS checks since 19 August 2025, from the published measurements. Samples from 3 communes on the same network: it's the same water, so each one applies to Entraygues-sur-Truyère.

“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 Entraygues-sur-Truyère safe to drink?

Yes. At the check on 8 July 2026, the tap water in Entraygues-sur-Truyère was within every limit tested. Outside a reference value: Electrical conductivity 161 µS/cm on 8 July 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Eau d'alimentation conforme aux exigences de qualité pour l'ensemble des paramètres analysés, à l'exception de la conductivité trop basse, caractéristique des eaux faiblement minéralisées.”

How high are PFAS levels in Entraygues-sur-Truyère's drinking water?

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

Does the water in Entraygues-sur-Truyère also meet the strictest limits in Europe?

The check cannot say. None of the four compounds was quantified, but the laboratory's detection limits add up to 6 ng/L, above Sweden's legal limit of 4 ng/L in force since 2026, so a value between the two would go unnoticed.

Are PFAS levels rising in Entraygues-sur-Truyère's tap water?

Too few quantified checks to say (0 since 19 August 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values. These history statistics use laboratory-published sums only.

How hard is the water in Entraygues-sur-Truyère?

The water hardness in Entraygues-sur-Truyère is 5.4 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
