PFAS in Étrechet's tap water: under 6.5 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
None of the 4 most harmful PFAS detected
The lab sees nothing below 6.5 ng/L, 13 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 Ardentes, on the same distribution network as Étrechet (ARDENTES ETRECHET). 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 0.5 to 5 ng/L upward. None reached that limit, so their total is below 6.5 ng/L rather than zero.

Frequently asked questions
Is tap water in Étrechet safe to drink?
At the latest check, the water was over at least one limit. “Eau d'alimentation non-conforme à la limite de qualité pour le paramètre nitrate (50 mg/l). Eau non recommandée aux femmes enceintes et aux nourrissons de moins de 6 mois.”
How high are PFAS levels in Étrechet's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 3.5 ng/L. The EU limit is 100 ng/L, so this water is at 3 % of the limit. (below the EU limit)
Does the water in Étrechet 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 6.5 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 Étrechet?
The water hardness in Étrechet is 14.3 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
