PFAS in Blanzay's tap water: under 4 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 4 ng/L, 8 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.
Sample taken in Saint-Pierre-d'Exideuil, on the same distribution network as Blanzay (SUD VIENNE ST PIERRE D'EX STATION). 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.
The lab detects each of the four substances from 1 ng/L upward. None reached that limit, so their total is below 4 ng/L rather than zero.

None found. The lab sees nothing below 4 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Blanzay, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 13 January 2026. The total is below 4 ng/L, the sum of the detection limits and 8 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,071 µg/L, below the EU legal limit (100 ng/L). Sampled in Saint-Pierre-d'Exideuil, on the same network. 5 checks since 10 April 2025, PFAS-4 always below the detection limit (4 ng/L).

Frequently asked questions
Is tap water in Blanzay safe to drink?
Yes. At the check on 13 January 2026, the tap water in Blanzay 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 Blanzay's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 71 ng/L. The EU limit is 100 ng/L, so this water is under 71 % of the limit. (below the EU limit)
Does the water in Blanzay also meet the strictest limits in Europe?
As far as this check can tell, yes. None of the four compounds was quantified, so their total is below 4 ng/L, the sum of the laboratory's detection limits, and under Sweden's legal limit of 4 ng/L in force since 2026.
Are PFAS levels rising in Blanzay's tap water?
No. Since 10 April 2025, 5 checks have been published and the PFAS-4 sum stayed below the laboratory's detection limit (4 ng/L) every time.
How hard is the water in Blanzay?
No hardness value is available for Blanzay in this source.
