PFAS in Pont-et-Massène's tap water: under 2.5 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 2.5 ng/L, 5 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 Arnay-sous-Vitteaux, on the same distribution network as Pont-et-Massène (SESAM, R. DE PONT). 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 0.5 to 1 ng/L upward. None reached that limit, so their total is below 2.5 ng/L rather than zero.

In Pont-et-Massène, 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 2.5 ng/L, the sum of the detection limits and 5 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <SEUIL µg/L, below the EU legal limit (100 ng/L). Sampled in Arnay-sous-Vitteaux, on the same network. 2 checks since 25 November 2025, PFAS-4 always below the detection limit.

PFAS over time in Pont-et-Massène
3 PFAS checks since 8 April 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Pont-et-Massène.
“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 |
|---|---|---|---|
| < detection limit | < detection limit | Arnay-sous-Vitteaux | |
| < detection limit | < detection limit | Pont-et-Massène | |
| < 2.5 ng/L · calculated | < detection limit | Pont-et-Massène |
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 Pont-et-Massène safe to drink?
Yes. At the check on 15 June 2026, the tap water in Pont-et-Massène was within every limit tested. “La teneur en COT n'est pas conforme à la référence de qualité nécessit ant une optimisation du traitement et une adaptation à la qualité de l 'eau brute.”
How high are PFAS levels in Pont-et-Massène'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 Pont-et-Massène 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 2.5 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 Pont-et-Massène's tap water?
Too few quantified checks to say (0 since 8 April 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 Pont-et-Massène?
The water hardness in Pont-et-Massène is 23.4 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
