PFAS in Le Monêtier-les-Bains's tap water: under 4 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 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.
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.

In Le Monêtier-les-Bains, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 12 May 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). 4 checks since 30 March 2026, PFAS-4 always below the detection limit (4 ng/L).

Frequently asked questions
Is tap water in Le Monêtier-les-Bains safe to drink?
At the latest check, the water was over at least one limit. “Eau non conforme aux limites de qualité fixées par le Code de la Santé Publique concernant les eaux destinées à la consommation humaine. Je vous transmettrai dès réception, le bulletin analytique corresponda nt, mais d’ores et déjà, en application de l'article L. 1321-4 du code de la santé publique, je vous demande d’engager toutes les mesures n écessaires à la recherche de la cause de la pollution (visite des capt ages et des alentours, des réservoirs, recherche de fuite….) et de pre ndre les mesures correctives afin d'y remédier (nettoyage des ouvrages , mise en place d’un traitement ponctuel ou définitif…). Dans un premi er temps, afin de désinfecter le réseau, il peut être envisagé d'intro duire une dose de chlore bien homogénéisée dans le réservoir (eau de j avel à usage ménager sans parfum) à raison de : - soit 1 berlingot de moins de 3 mois (250 ml à 9,6 % de chlore acti f soit 36° Chlorométrique) pour 100 m3. - soit 1,5 litre d'une solution (de moins de 6 mois) à 2,6% de chlore actif, soit 9° chlorométrique pour 100 m3. Vous voudrez bien me tenir informée des mesures prises. De nouveaux contrôles seront effectués à notre initiative afin de véri fier l’efficacité des mesures correctives prises.”
How high are PFAS levels in Le Monêtier-les-Bains'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 Le Monêtier-les-Bains 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 Le Monêtier-les-Bains's tap water?
Too few quantified checks to say (0 since 6 November 2024). 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 Le Monêtier-les-Bains?
The water hardness in Le Monêtier-les-Bains is 12.4 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
