PFAS in Carros's tap water: 2 ng/L, 4x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
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 Carros, the 4 most closely watched PFAS (PFAS-4) add up to 2 ng/L (0.002 µg/L) at the latest PFAS check on 1 July 2026. That's 4 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 5 ng/L (0.005 µg/L), below the EU legal limit (100 ng/L). 2 checks since 28 May 2026: PFAS-4 from 2 ng/L to 2 ng/L.

PFAS over time in Carros
5 PFAS checks since 10 January 2025, from the published measurements. Samples come from 3 distribution networks. The trend refers to the network “RÉSEAU CARROS LE NEUF”.
“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 Carros safe to drink?
Yes. At the check on 17 July 2026, the tap water in Carros 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 Carros's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 5 ng/L. The EU limit is 100 ng/L, so this water is at 5 % of the limit. (below the EU limit)
Does the water in Carros 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 ng/L stays below.
Are PFAS levels rising in Carros's tap water?
Too few quantified checks to say (1 since 10 January 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values. These history statistics use laboratory-published sums only.
How hard is the water in Carros?
The water hardness in Carros is 26.9 °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.
