PFAS in Champis's tap water: 8 ng/L, 16x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
16× 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 Cornas, on the same distribution network as Champis (SCPV GRANDE TRAVERSE). 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).
More PFAS than in 95% of the cities we track

In Champis, the 4 most closely watched PFAS (PFAS-4) add up to 8 ng/L (0.008 µg/L) at the latest PFAS check on 31 July 2026. That's 16 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). Sampled in Cornas, on the same network. 5 checks since 25 August 2025: PFAS-4 from 6 ng/L to 17 ng/L, averaging 10 ng/L over 12 months. Falling on the main network.

Details and sources
PFAS over time in Champis
6 PFAS checks since 22 May 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Champis.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.
| Date | PFAS-4 | Sum of 20 PFAS | Sampled at |
|---|---|---|---|
| 8 ng/L | 31 ng/L | Cornas | |
| 10 ng/L | 39 ng/L | Cornas | |
| 6 ng/L | 16 ng/L | Saint-Péray | |
| 9 ng/L | 30 ng/L | Saint-Péray | |
| 17 ng/L | 49 ng/L | Cornas | |
| 5 ng/L – < 7 ng/L · calculated | 18 ng/L | Saint-Péray |
Calculated values: “<” is an upper bound from published thresholds, “≥” a lower bound, “–” means no published sum or complete measurement. How to read a PFAS result

Frequently asked questions
Is tap water in Champis safe to drink?
Yes. At the check on 31 July 2026, the tap water in Champis 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 Champis'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 Champis also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 8 ng/L. That is 2 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 Champis's tap water?
No, they are falling. On the main network, the PFAS-4 sum went from 17 ng/L (25 August 2025) to 8 ng/L (31 July 2026) across 5 quantified checks. These history statistics use laboratory-published sums only.
How hard is the water in Champis?
No hardness value is available for Champis in this source.
Where does this data come from?
