Amount found in the water 9 ng/L 0.009 µg/L · the 4 most harmful PFAS (PFAS-4)
Our health benchmark 0.5 ng/L

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.

Substances below the detection limit count as 0, so the real total may be higher.

One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

In Déols, the 4 most closely watched PFAS (PFAS-4) add up to 9 ng/L (0.009 µg/L) at the latest PFAS check on 22 June 2026. That's 18 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 15 ng/L (0.015 µg/L), below the EU legal limit (100 ng/L). 18 checks since 6 May 2024: sum of 20 PFAS from 2.1 ng/L to 74 ng/L.

PFAS over time in Déols

18 PFAS checks since 6 May 2024, from the published measurements. Samples from 3 communes on the same network: it's the same water, so each one applies to Déols. Samples come from 7 distribution networks. The trend refers to the network “DEOLS VILLE”.

“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 Déols 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 nitrate (50 mg/l) et Nitrates/50 + Nitrites/3. Eau non recommandée aux femmes enceintes et aux nourrissons de moins de 6 mois. Recontrôle programmé.”

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

The total of 20 PFAS ("forever chemicals") was last measured at 15 ng/L. The EU limit is 100 ng/L, so this water is at 15 % of the limit. (below the EU limit)

Does the water in Déols also meet the strictest limits in Europe?

No. The four most harmful PFAS add up to 9 ng/L. That is 2.3 times Sweden's legal limit of 4 ng/L, in force since 2026. Germany will set a similar one in 2028. The water still passes the current EU legal limit (100 ng/L for the total of 20 PFAS).

Are PFAS levels rising in Déols'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 Déols?

The water hardness in Déols is 24.1 °f (medium). 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 21 September 2026.
