PFAS in Andance's tap water: 18 ng/L, 36x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
36× 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.
Sample taken in Bogy, on the same distribution network as Andance (SYND ANN. SERR. UDI TERRES CARREES). 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.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).
More PFAS than in 98% of the cities we track

In Andance, the 4 most closely watched PFAS (PFAS-4) add up to 18 ng/L (0.018 µg/L) at the latest PFAS check on 7 April 2026. That's 36 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 47 ng/L (0.047 µg/L), below the EU legal limit (100 ng/L). Sampled in Bogy, on the same network. 9 checks since 19 August 2025: PFAS-4 from 7 ng/L to 26 ng/L, averaging 23.5 ng/L over 12 months. Falling on the main network.

Frequently asked questions
Is tap water in Andance safe to drink?
Yes. At the check on 7 April 2026, the tap water in Andance 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 Andance's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 47 ng/L. The EU limit is 100 ng/L, so this water is at 47 % of the limit. (below the EU limit)
Does the water in Andance also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 18 ng/L. That is 4.5 times Sweden's legal limit of 4 ng/L, in force since 2026. Germany will set a similar one in 2028. The water still passes the current EU legal limit (100 ng/L for the total of 20 PFAS).
Are PFAS levels rising in Andance's tap water?
No, they are falling. On the main network, the PFAS-4 sum went from 24 ng/L (19 August 2025) to 18 ng/L (7 April 2026) across 6 quantified checks. These history statistics use laboratory-published sums only.
How hard is the water in Andance?
The water hardness in Andance is 27 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 12 September 2026.
