PFAS in Saint-Salvadour'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.
Sample taken in Madranges, on the same distribution network as Saint-Salvadour (BEAUMONT ST SALVADOUR). 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.

In Saint-Salvadour, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 30 July 2025. 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: <SEUIL µg/L, below the EU legal limit (100 ng/L). Sampled in Madranges, on the same network. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions
Is tap water in Saint-Salvadour safe to drink?
At the latest check, the water was over at least one limit. “Limite de qualité des eaux fixées par le Code de la Santé Publique (Ar t. R 1321-1 à R 1321-68) non satisfaite pour le paramètre chlorure de vinyle monomère. Cette non conformité fait l'objet d'une surveillance renforcée par l'ARS Nouvelle Aquitaine, aussi, des recontrôles seront programmés. La collectivité est incitée à identifier les points à risq ue sur son réseau pour envisager les renouvellements de canalisations nécessaires. Références de qualité des eaux fixées par le Code de la Santé Publique (Art. R 1321-1 à R 1321-68) non satisfaites pour les paramètres turbi dité, pH et conductivité. La faible valeur du pH mesuré confirme la tr ès faible minéralisation de l'eau distribuée et donc son agressivité v is à vis des métaux. La mise en place d'un traitement correctif bien d imensionné est nécessaire.”
How high are PFAS levels in Saint-Salvadour'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 Saint-Salvadour 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.
How hard is the water in Saint-Salvadour?
The water hardness in Saint-Salvadour is 0 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
