PFAS in drinking water

No PFAS detected

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.

Sample taken in Laboule, on the same distribution network as Beaumont (BEAUMONT 2 AYGUES EAUX MARECHE). 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 ng/L upward. None reached that limit, so their total is below 4 ng/L rather than zero.

None found. The lab sees nothing below 4 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Beaumont, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 12 June 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: <0,029 µg/L, below the EU legal limit (100 ng/L). Sampled in Laboule, on the same network. 9 checks since 26 August 2025, PFAS-4 always below the detection limit (4 ng/L).

PFAS over time in Beaumont

11 PFAS checks since 27 May 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Beaumont. Samples come from 6 distribution networks. The trend refers to the network “BEAUMONT 2 AYGUES EAUX MARECHE”.

“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 Beaumont safe to drink?

Yes. At the check on 29 July 2026, the tap water in Beaumont was within every limit tested. Outside a reference value: Electrical conductivity 53 µS/cm on 29 July 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité.”

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

At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 29 ng/L. The EU limit is 100 ng/L, so this water is under 29 % of the limit. (below the EU limit)

Does the water in Beaumont 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 Beaumont's tap water?

No. Since 27 May 2025, 9 checks have been published and the PFAS-4 sum stayed below the laboratory's detection limit (4 ng/L) every time. These history statistics use laboratory-published sums only.

How hard is the water in Beaumont?

The water hardness in Beaumont is 1.7 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
