PFAS in drinking water

None of the 4 most harmful PFAS detected

Amount found in the water < 4 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, 6 ng/L found in total
Our health benchmark 0.5 ng/L

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 Auvilliers-en-Gâtinais, on the same distribution network as Ouzouer-sous-Bellegarde (SYNDICAT DES EAUX D'AUVILLIERS). 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.

None found. The lab sees nothing below 4 ng/L, so our 0.5 ng/L benchmark cannot be checked.

Frequently asked questions

Is tap water in Ouzouer-sous-Bellegarde safe to drink?

Yes. At the check on 14 August 2025, the tap water in Ouzouer-sous-Bellegarde was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés. La teneur en chlorure de vinyle monomère ne vaut que pour le secteur où elle a été mesurée.”

How high are PFAS levels in Ouzouer-sous-Bellegarde's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 6 ng/L. The EU limit is 100 ng/L, so this water is at 6 % of the limit. (below the EU limit)

Does the water in Ouzouer-sous-Bellegarde 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.
