Amount found in the water < 4 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 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.

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.

In Ormoy, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 28 April 2026. The total is below 4 ng/L, the sum of the detection limits and 8 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,001 µg/L, below the EU legal limit (100 ng/L). 2 checks since 5 June 2024, sum of 20 PFAS always below the detection limit (1 ng/L).

PFAS over time in Ormoy

2 PFAS checks since 5 June 2024, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Ormoy.

“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Frequently asked questions

Is tap water in Ormoy safe to drink?

At the latest check, the water was over at least one limit. “Eau d'alimentation non-conforme aux limites de qualité pour les paramètres Chloridazone Desphényl et Chlorothalonil SA. Un suivi renforcé est mis en place.Les résultats d'analyses de ce prél èvement ont mis en évidence un dépassement de la valeur indicative de 0,9 µg/L sur un métabolite de pesticide non pertinent, ne nécessitant pas de restriction de consommation de l’eau d’après l’expertise de l’Agence Nationale de Sécurité Sanitaire de l'Alimentation, de l'Environnement et du Travail (ANSES). On observe également une teneur en perchlorates supérieure au seuil de 4 µg/l. Conformément à l'avis de l'ANSES, il convient de recommander à la population de limiter l'usage de l'eau du robinet pour les nourri ssons de moins de 6 mois et de privilégier l'utilisation d'eau emboute illée pour la préparation des biberons.”

How high are PFAS levels in Ormoy's drinking water?

At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 1 ng/L. The EU limit is 100 ng/L, so this water is under 1 % of the limit. (below the EU limit)

Does the water in Ormoy 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.

Are PFAS levels rising in Ormoy'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 Ormoy?

The water hardness in Ormoy is 24 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
