PFAS in drinking water

No PFAS detected

Amount found in the water < 13 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 13 ng/L, 26 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 1.5 to 5 ng/L upward. None reached that limit, so their total is below 13 ng/L rather than zero.

None found. The lab sees nothing below 13 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Omps, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 2 April 2026. The total is below 13 ng/L, the sum of the detection limits and 26 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,0895 µg/L, below the EU legal limit (100 ng/L). 2 checks since 9 October 2025, PFAS-4 always below the detection limit (13 ng/L).

PFAS over time in Omps

2 PFAS checks since 9 October 2025, values as published. Samples from 2 communes on the same network: it's the same water, so each one applies to Omps.

Frequently asked questions

Is tap water in Omps safe to drink?

Yes. At the check on 2 April 2026, the tap water in Omps was within every limit tested. “Résultats d'analyses conformes à la norme. Cependant, taux de chlore é levé et présence d'ESA Metolachlore traduisant la vulnérabilité de la ressource vis à vis des pesticides. Il est demandé au distributeur d'eau d'en identifier préventivement l'origine possible.De plus, cette eau présente un caractère agressif : elle peut dissoudre les matériaux à son contact : eau de qualité sanitaire non satisfaisante.”

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

At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 89.5 ng/L. The EU limit is 100 ng/L, so this water is under 89 % of the limit. (below the EU limit)

Does the water in Omps 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 13 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 Omps's tap water?

Too few quantified checks to say (0 since 9 October 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.

How hard is the water in Omps?

The water hardness in Omps is 10 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?

All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 12 September 2026.
