PFAS in Saint-Germain-lès-Senailly's tap water: 1.42 ng/L, 2.8x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
2.8× above our health benchmark
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.
Substances below the detection limit count as 0, so the real total may be higher.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

In Saint-Germain-lès-Senailly, the 4 most closely watched PFAS (PFAS-4) add up to 1.42 ng/L (0.0014 µg/L) at the latest PFAS check on 24 June 2026. That's 2.8 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 4.42 ng/L (0.0044 µg/L), below the EU legal limit (100 ng/L). 2 checks since 13 October 2025: PFAS-4 from 1.42 ng/L to 2.3 ng/L.

Frequently asked questions
Is tap water in Saint-Germain-lès-Senailly safe to drink?
At the latest check, the water was over at least one limit. “La teneur en nitrates est supérieure à la limite de qualité. En conséquence, l'interdiction de consommer cette eau pour les femmes enceintes et les nourrissons de moins de 6 mois est maintenue. Conformément à l'arrêté préfectoral du 19/11/2021, la collectivité est mise en demeure de distribuer une eau conforme.”
How high are PFAS levels in Saint-Germain-lès-Senailly's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 4.42 ng/L. The EU limit is 100 ng/L, so this water is at 4 % of the limit. (below the EU limit)
Does the water in Saint-Germain-lès-Senailly also meet the strictest limits in Europe?
Yes. Even against Europe's strictest legal limit, Sweden's 4 ng/L in force since 2026, the measured value of 1.42 ng/L stays below.
Are PFAS levels rising in Saint-Germain-lès-Senailly's tap water?
Too few quantified checks to say (2 since 13 October 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.
How hard is the water in Saint-Germain-lès-Senailly?
The water hardness in Saint-Germain-lès-Senailly is 29.7 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
