PFAS in Chanteix's tap water: under 14 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 14 ng/L, 28 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 Saint-Mexant, on the same distribution network as Chanteix (MAUMONT RESEAU PRINCIPAL NORD). 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 to 5 ng/L upward. None reached that limit, so their total is below 14 ng/L rather than zero.

In Chanteix, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 21 May 2026. The total is below 14 ng/L, the sum of the detection limits and 28 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <SEUIL µg/L, below the EU legal limit (100 ng/L). Sampled in Saint-Mexant, on the same network. 2 checks since 3 April 2025, sum of 20 PFAS always below the detection limit.

PFAS over time in Chanteix
2 PFAS checks since 3 April 2025, from the published measurements.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.
| Date | PFAS-4 | Sum of 20 PFAS | Sampled at |
|---|---|---|---|
| < 14 ng/L · calculated | < detection limit | Saint-Mexant | |
| < 4 ng/L · calculated | < detection limit | Saint-Mexant |
Calculated values: “<” is an upper bound from published thresholds, “≥” a lower bound, “–” means no published sum or complete measurement. How to read a PFAS result

Frequently asked questions
Is tap water in Chanteix 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 (Art. R 1321-1 à R 1321-68) non satisfaite pour le paramètre chlorure de vinyle monomère. Un prélèvement de recontrôle a été programmé suite à la réalisation des actions correctives demandées à l'exploitant (purges de réseau). Dans l'attente du renouvellement de la canalisation incriminée, des purges sur cette portion de réseau doivent être réalisées régulièrement afin de réduire ce taux de chlorure de vinyle.”
How high are PFAS levels in Chanteix'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 Chanteix 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 14 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 Chanteix's tap water?
Calculated PFAS-4 values are listed in the table. The chart uses laboratory-published sum-of-20 results; there are too few laboratory-published PFAS-4 sums for the existing trend calculation.
How hard is the water in Chanteix?
The water hardness in Chanteix is 9.2 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
