Drinking water quality in Barr
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at 0.017 µg/L. The EU limit is 0.1 µg/L, so this water is at 17 % of the limit. (13 January 2026)
The four most harmful PFAS add up to 0.007 µg/L. That is 1.8 times the health limit of 0.004 µg/L that Sweden made law in 2026. Germany will set a similar limit in 2028.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).
Substances too small to measure count as 0, so the real total may be higher.

Official assessment
The latest official test passed all quality requirements.
„Eau destinée à la consommation humaine conforme aux limites de qualité réglementaires pour les paramètres analysés. Eau douce très faiblement minéralisée (conductivité inférieure à 200 µs/cm) susceptible, dans certaines conditions défavorables (stagna tion, chauffe-eau...) de dissoudre certains métaux des canalisations. Le matin ou après quelques jours d'absence, il est conseillé de ne con sommer l'eau du robinet qu'après un écoulement de 15 à 30 secondes. Vérifiez l'absence de canalisations en plomb dans les parties privatives du réseau.“

Frequently asked questions
Is tap water in Barr safe to drink?
Yes. The latest official test (4 June 2026) checked the tap water in Barr and it passed every requirement.
How high are PFAS levels in Barr's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 0.017 µg/L. The EU limit is 0.1 µg/L, so this water is at 17 % of the limit. (below the EU limit)
Does the water in Barr also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 0.007 µg/L. That is 1.8 times the health limit of 0.004 µg/L that Sweden made law in 2026. The water still passes the current EU limit (0.1 µg/L for the total of 20 PFAS).
How hard is the water in Barr?
The water hardness in Barr is 4.5 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
