PFAS in Taconnay's tap water: under 4 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
None of the 4 most harmful 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 Monceaux-le-Comte, on the same distribution network as Taconnay (MONTCEAUX LE COMTE). 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.

In Taconnay, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 2 June 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: 10 ng/L (0.01 µg/L), below the EU legal limit (100 ng/L). Sampled in Monceaux-le-Comte, on the same network. 2 checks since 29 August 2025, PFAS-4 always below the detection limit (4 ng/L).

Details and sources
PFAS over time in Taconnay
3 PFAS checks since 27 June 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Taconnay. Samples come from 2 distribution networks. The trend refers to the network “MONTCEAUX LE COMTE”.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.
| Date | PFAS-4 | Sum of 20 PFAS | Sampled at | Network |
|---|---|---|---|---|
| < 4 ng/L | 10 ng/L | Monceaux-le-Comte | MONTCEAUX LE COMTE | |
| < 4 ng/L | < 29 ng/L | Monceaux-le-Comte | MONTCEAUX LE COMTE | |
| < 4 ng/L · calculated | < 28 ng/L | Chevannes-Changy | CHEVANNES-CHANGY |
Calculated values: “<” is an upper bound from published thresholds, “≥” a lower bound, “–” means no published sum or complete measurement. How to read a PFAS result

Frequently asked questions
Is tap water in Taconnay safe to drink?
At the latest check, the water was over at least one limit. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés. Une dérogation temporaire aux limit es de qualité des eaux destinées à la consommation humaine applicable au paramètre fluor et portant restriction des usages de l’eau à des fi ns alimentaires pour les nourrissons et les enfants (jusqu’à 12 ans) e st accordée au SIAEP de Charles Chaigneau par arrêté préfectoral n°58- 2022-04-26-0002 du 26 avril 2022.”
How high are PFAS levels in Taconnay's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 10 ng/L. The EU limit is 100 ng/L, so this water is at 10 % of the limit. (below the EU limit)
Does the water in Taconnay 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 Taconnay's tap water?
Too few quantified checks to say (0 since 27 June 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 Taconnay?
No hardness value is available for Taconnay in this source.
