PFAS in drinking water

14× above our health benchmark

Amount found in the water 7 ng/L 0.007 µg/L · the 4 most harmful PFAS (PFAS-4)
Our health benchmark 0.5 ng/L

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 Parves et Nattages, on the same distribution network as Massignieu-de-Rives (MASSIGNIEU NATTAGES PARVES). 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.

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 Massignieu-de-Rives, the 4 most closely watched PFAS (PFAS-4) add up to 7 ng/L (0.007 µg/L) at the latest PFAS check on 29 June 2026. That's 14 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 8 ng/L (0.008 µg/L), below the EU legal limit (100 ng/L). Sampled in Parves et Nattages, on the same network. 2 checks since 13 January 2025: sum of 20 PFAS from 8 ng/L to 8 ng/L.

Frequently asked questions

Is tap water in Massignieu-de-Rives safe to drink?

All the values shown here (29 June 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”

How high are PFAS levels in Massignieu-de-Rives's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 8 ng/L. The EU limit is 100 ng/L, so this water is at 8 % of the limit. (below the EU limit)

Does the water in Massignieu-de-Rives also meet the strictest limits in Europe?

No. The four most harmful PFAS add up to 7 ng/L. That is 1.75 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 Massignieu-de-Rives's tap water?

For Massignieu-de-Rives, 2 checks have been published since 13 January 2025, but the laboratory only recently started reporting the PFAS-4 sum. The history above shows the sum of 20 PFAS; a PFAS-4 trend will appear once enough values exist.

How hard is the water in Massignieu-de-Rives?

The water hardness in Massignieu-de-Rives is 30.2 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
