PFAS in Bourg-Saint-Maurice's tap water: under 4 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 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.
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.

In Bourg-Saint-Maurice, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 19 February 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). 12 checks since 27 August 2025: PFAS-4 up to 2 ng/L, sometimes below the detection limit, averaging at least 1 ng/L over 12 months (non-detects as 0).

PFAS over time in Bourg-Saint-Maurice
16 PFAS checks since 25 February 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Bourg-Saint-Maurice. Samples come from 10 distribution networks. The trend refers to the network “BOURG ST MAURICE ARCS 1800”.
“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 Bourg-Saint-Maurice safe to drink?
Yes. At the check on 28 July 2026, the tap water in Bourg-Saint-Maurice 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 Bourg-Saint-Maurice'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 Bourg-Saint-Maurice 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 Bourg-Saint-Maurice's tap water?
Too few quantified checks to say (2 since 25 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 Bourg-Saint-Maurice?
The water hardness in Bourg-Saint-Maurice is 17 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
