PFAS in the tap water of Rouffiac (Cantal): 2.2 ng/L, 4.4x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
4.4× 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 Rouffiac, the 4 most closely watched PFAS (PFAS-4) add up to 2.2 ng/L (0.0022 µg/L) at the latest PFAS check on 2 October 2025. That's 4.4 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 2.2 ng/L (0.0022 µg/L), below the EU legal limit (100 ng/L). 2 checks since 2 October 2025, PFAS-4 always below the detection limit (4 ng/L).

Frequently asked questions
Is tap water in Rouffiac safe to drink?
Yes. At the check on 21 May 2026, the tap water in Rouffiac was within every limit tested. Outside a reference value: pH 6.4 unité pH on 21 May 2026 (reference 6.5–9 unité pH), Electrical conductivity 94 µS/cm on 21 May 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Eau de qualité sanitaire satisfaisante.”
How high are PFAS levels in Rouffiac's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 2.2 ng/L. The EU limit is 100 ng/L, so this water is at 2 % of the limit. (below the EU limit)
Does the water in Rouffiac 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 2.2 ng/L stays below.
Are PFAS levels rising in Rouffiac's tap water?
Too few quantified checks to say (0 since 2 October 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.
How hard is the water in Rouffiac?
The water hardness in Rouffiac is 3 °f (soft). 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.
