PFAS in drinking water

No PFAS detected

Amount found in the water < 11 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 11 ng/L, 22 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 Chantonnay, on the same distribution network as La Réorthe (RESERVOIR DE LA LEUE). 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 2 to 5 ng/L upward. None reached that limit, so their total is below 11 ng/L rather than zero.

None found. The lab sees nothing below 11 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In La Réorthe, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 15 June 2026. The total is below 11 ng/L, the sum of the detection limits and 22 times our 0.5 ng/L benchmark. Sum of 20 PFAS: not detected, below the EU legal limit (100 ng/L). Sampled in Chantonnay, on the same network. 5 checks since 12 March 2025, sum of 20 PFAS always below the detection limit.

PFAS over time in La Réorthe

5 PFAS checks since 12 March 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to La Réorthe.

“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 La Réorthe safe to drink?

All the values shown here (21 July 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”

How high are PFAS levels in La Réorthe's drinking water?

At the latest check the total of 20 PFAS ("forever chemicals") was reported as not detected; the laboratory did not state its reporting limit. The EU limit is 100 ng/L. (below the EU limit)

Does the water in La Réorthe 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 11 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 La Réorthe'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 La Réorthe?

The water hardness in La Réorthe is 15.6 °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 28 September 2026.

Same water network

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