PFAS in Les Vastres's tap water: under 8 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 8 ng/L, 16 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 Fay-sur-Lignon, on the same distribution network as Les Vastres (BOURG FAY - CREAUX). 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 2 ng/L upward. None reached that limit, so their total is below 8 ng/L rather than zero.

In Les Vastres, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 3 March 2026. The total is below 8 ng/L, the sum of the detection limits and 16 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,005 µg/L, below the EU legal limit (100 ng/L). Sampled in Fay-sur-Lignon, on the same network. 2 checks since 26 January 2026, PFAS-4 always below the detection limit (2 ng/L).

Frequently asked questions
Is tap water in Les Vastres safe to drink?
Yes. At the check on 22 June 2026, the tap water in Les Vastres was within every limit tested. Outside a reference value: pH 6.2 unité pH on 22 June 2026 (reference 6.5–9 unité pH), Electrical conductivity 35 µS/cm on 22 June 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Prélèvement réalisé suite à la non conformité bactériologique enregistrée sur le réseau de distribution du Bourg le 15/06/2026. EAU CONFORME AUX NORMES EAUX DE DISTRIBUTION. EAU DE QUALITE SANITAIRE SATISFAISANTE. A noter un pH et une conductivité inférieurs aux références de qualité traduisant un risque de corrosion.”
How high are PFAS levels in Les Vastres's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 5 ng/L. The EU limit is 100 ng/L, so this water is under 5 % of the limit. (below the EU limit)
Does the water in Les Vastres 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 8 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 Les Vastres's tap water?
Too few quantified checks to say (0 since 26 January 2026). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.
How hard is the water in Les Vastres?
The water hardness in Les Vastres is 1.1 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
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 12 September 2026.
