PFAS in drinking water

No PFAS detected

Amount found in the water < 6 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 6 ng/L, 12 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 Saint-Pol-de-Léon, on the same distribution network as Cléder (HAUT-LEON (SUEZ)). 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 to 2 ng/L upward. None reached that limit, so their total is below 6 ng/L rather than zero.

None found. The lab sees nothing below 6 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Cléder, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 3 March 2026. The total is below 6 ng/L, the sum of the detection limits and 12 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <SEUIL µg/L, below the EU legal limit (100 ng/L). Sampled in Saint-Pol-de-Léon, on the same network. 4 checks since 3 June 2025: PFAS-4 up to 2.3 ng/L, sometimes below the detection limit, averaging at least 0.58 ng/L over 12 months (non-detects as 0).

PFAS over time in Cléder

5 PFAS checks since 4 February 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Cléder. Samples come from 2 distribution networks. The trend refers to the network “HAUT-LEON (SUEZ)”.

“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 Cléder safe to drink?

Yes. At the check on 3 March 2026, the tap water in Cléder was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”

How high are PFAS levels in Cléder'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 Cléder 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 6 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 Cléder's tap water?

Too few quantified checks to say (1 since 4 February 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values. These history statistics use laboratory-published sums only.

How hard is the water in Cléder?

The water hardness in Cléder is 13 °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.

Same water network

Same distribution network as Cléder, so in principle the same water.
