PFAS in Sévérac d'Aveyron's tap water: under 6 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
No PFAS detected
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.
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.

PFAS over time in Sévérac d'Aveyron
5 PFAS checks since 8 September 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Sévérac d'Aveyron. Samples come from 4 distribution networks. The trend refers to the network “SEVERAC LE CHATEAU”.
“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 Sévérac d'Aveyron safe to drink?
Yes. At the check on 23 July 2026, the tap water in Sévérac d'Aveyron 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 Sévérac d'Aveyron'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 Sévérac d'Aveyron 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 Sévérac d'Aveyron's tap water?
Too few quantified checks to say (0 since 8 September 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 Sévérac d'Aveyron?
The water hardness in Sévérac d'Aveyron is 0 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
