PFAS in Brasparts's tap water: under 6 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
No PFAS detected
The lab sees nothing below 6 ng/L, 12 times our benchmark of 0.5 ng/L. Water above our benchmark would pass this check unnoticed.
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.
The lab detects each of the four substances from 1 to 2 ng/L upward. None reached that limit, so their total is below 6 ng/L rather than zero.

In Brasparts, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 3 March 2026. The total is below 6 ng/L, the sum of the detection limits and 12 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <SEUIL µg/L, below the EU legal limit (100 ng/L). 5 checks since 24 April 2025, PFAS-4 always below the detection limit.

Frequently asked questions
Is tap water in Brasparts safe to drink?
Yes. At the check on 26 June 2026, the tap water in Brasparts was within every limit tested. Outside a reference value: pH 4.8 unité pH on 26 June 2026 (reference 6.5–9 unité pH), Electrical conductivity 70 µS/cm on 26 June 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Eau d’alimentation conforme aux limites de qualité mais ne satisfaisant pas totalement aux références de qualité en raison d’un dépassement de la valeur de référence de 200µg/L pour l'aluminium, d'une une conductivité inférieure à la valeur de référence minimale de 200µS/cm et un pH inférieur à la référence minimale de 6,5. Ces paramètres traduisent le caractère agressif de l’eau, susceptible d’interagir avec les matériaux constitutifs des canalisations, sans incidence directe sur la santé du consommateur. A noter une température élevée de l’eau pouvant stimuler la croissance des micro-organismes et accroître les problèmes liés au goût, à l’odeur, à la coloration et à la corrosion.”
How high are PFAS levels in Brasparts's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at –. The EU limit is 100 ng/L, so this water is at – of the limit. (below the EU limit)
Does the water in Brasparts also meet the strictest limits in Europe?
The check cannot say. None of the four compounds was quantified, but the laboratory's detection limits add up to 6 ng/L, above Sweden's legal limit of 4 ng/L in force since 2026, so a value between the two would go unnoticed.
Are PFAS levels rising in Brasparts's tap water?
No. Since 24 April 2025, 5 checks have been published and the PFAS-4 sum stayed below the laboratory's detection limit every time.
How hard is the water in Brasparts?
The water hardness in Brasparts is 0 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
