PFAS in drinking water

No PFAS detected

Amount found in the water < 8 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 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 Courcelles-sur-Voire, on the same distribution network as Lentilles (NORD DE LA VOIRE RESEAU). 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 Lentilles, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 20 May 2025. 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).

Frequently asked questions

Is tap water in Lentilles safe to drink?

At the latest check, the water was over at least one limit. “Compte-tenu des paramètres contrôlés, cette eau est non conforme aux limites de qualité des eaux destinées à la consommation humaine, définies par l'arrêté du 11 janvier 2007 de par une teneur en CHLORIDAZONE DESPHÉNYL, considérée comme un métabolite de pesticide pertinent, qui a été détecté à une teneur de 0,172 µg/l. Cependant, au vu de la valeur sanitaire transitoire propre à la molécule détectée, cette teneur, bien que constituant une non-conformité, ne présentent pas de risque sanitaire pour le consommateur. L’EAU PEUT DONC ETRE CONSOMMEE SANS RESTRICTION. Dans une telle situation, le distributeur doit : informer la population, renforcer le suivi de la qualité et engager un programme visant à améliorer la situation. Il est à noter que cette analyse a été réalisée dans le cadre du suivi renforcé en place sur votre réseau de distribution pour la/les familles de pesticides concernées.”

How high are PFAS levels in Lentilles'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 Lentilles 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.

How hard is the water in Lentilles?

No hardness value is available for Lentilles in this source.

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.
