PFAS in Sommery's tap water: under 5 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
No PFAS detected
The lab sees nothing below 5 ng/L, 10 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 Montérolier, on the same distribution network as Sommery (MONTEROLIER). 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 5 ng/L rather than zero.

None found. The lab sees nothing below 5 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Sommery, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 13 February 2025. The total is below 5 ng/L, the sum of the detection limits and 10 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <SEUIL µg/L, below the EU legal limit (100 ng/L). Sampled in Montérolier, on the same network. 2 checks since 23 January 2025, sum of 20 PFAS always below the detection limit.

Details and sources
PFAS over time in Sommery
2 PFAS checks since 23 January 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Sommery. Samples come from 2 distribution networks. The trend refers to the network “SOMMERY BS”.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.
| Date | PFAS-4 | Sum of 20 PFAS | Sampled at | Network |
|---|---|---|---|---|
| < 5 ng/L · calculated | < detection limit | Montérolier | MONTEROLIER | |
| < 5 ng/L · calculated | < detection limit | Sommery | SOMMERY BS |
Calculated values: “<” is an upper bound from published thresholds, “≥” a lower bound, “–” means no published sum or complete measurement. How to read a PFAS result

Frequently asked questions
Is tap water in Sommery safe to drink?
Yes. At the check on 4 March 2026, the tap water in Sommery 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 Sommery'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 Sommery 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 5 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 Sommery'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 Sommery?
The water hardness in Sommery is 49.8 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
