PFAS in Courteix'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 Couffy-sur-Sarsonne, on the same distribution network as Courteix (BONGUE MONTEIL). 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.

Frequently asked questions
Is tap water in Courteix safe to drink?
Yes. At the check on 20 July 2026, the tap water in Courteix was within every limit tested. Outside a reference value: Electrical conductivity 144 µS/cm on 20 July 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Examen conforme aux limites de qualité fixées par le Code de la Santé Publique (Art. R 1321-1 à R 1321-68). Référence de qualité des eaux fixée par le Code de la Santé Publique (Art. R 1321-1 à R 1321-68) non satisfaite pour le paramètre conductivité. De par sa faible minéralisation, cette eau est agressive vis à vis des métaux.”
How high are PFAS levels in Courteix'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 Courteix 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 Courteix?
No hardness value is available for Courteix in this source.
