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.

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 Renage, the 4 most closely watched PFAS (PFAS-4) add up to 28 ng/L (0.028 µg/L) at the latest PFAS check on 17 July 2026. That's 56 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 31 ng/L (0.031 µg/L), below the EU legal limit (100 ng/L). 19 checks since 5 August 2025: PFAS-4 from 6 ng/L to 126 ng/L, averaging 91.5 ng/L over 12 months. No clear trend.

PFAS over time in Renage

32 PFAS checks since 27 May 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Renage. Samples come from 4 distribution networks. The trend refers to the network “RENAGE PRINCIPALE”.

“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 Renage safe to drink?

Yes. At the check on 17 July 2026, the tap water in Renage 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 Renage's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 31 ng/L. The EU limit is 100 ng/L, so this water is at 31 % of the limit. (below the EU limit)

Does the water in Renage also meet the strictest limits in Europe?

No. The four most harmful PFAS add up to 28 ng/L. That is 7 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 Renage's tap water?

No clear trend. Since 27 May 2025, 19 checks have been published; on the main network the PFAS-4 sum ranged between 53 ng/L and 119 ng/L (8 quantified values), at times below the detection limit. pfasnearme only reports a trend from a change of at least 25 % and 1 ng/L. These history statistics use laboratory-published sums only.

How hard is the water in Renage?

The water hardness in Renage is 27.3 °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 21 September 2026.
