PFAS in Bourg-de-Péage'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-de-Péage, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 2 April 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). 4 checks since 25 June 2025: PFAS-4 up to 1 ng/L, sometimes below the detection limit.

Frequently asked questions
Is tap water in Bourg-de-Péage safe to drink?
Yes. At the check on 29 July 2026, the tap water in Bourg-de-Péage was within every limit tested. “Eau d'alimentation conforme aux limites de qualité en vigueur. La référence de qualité fixée à 25°C pour la température est dépassée. Ce paramètre n'est représentatif que du lieu de prélèvement. Le résultat « ILLISIBL » correspond à un envahissement de la membrane par des colonies non caractéristiques, empêchant l'interprétation du paramètre coliformes. Ce paramètre étant une référence de qualité, ce résultat n'entraîne pas de non-conformité du prélèvement. Un entretien des ouvrages et une chloration préventive du réseau sont préconisés ainsi que la recherche des causes possibles d'altération de la qualité de l'eau.”
How high are PFAS levels in Bourg-de-Péage'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-de-Péage 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-de-Péage's tap water?
Too few quantified checks to say (0 since 25 June 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.
How hard is the water in Bourg-de-Péage?
The water hardness in Bourg-de-Péage is 30.3 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
