PFAS in Nouvoitou's tap water: under 3.4 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 3.4 ng/L, 6.8 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 Acigné, on the same distribution network as Nouvoitou (CEBR_PLESSIS BEUCHER_ACIGNE). 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 0.4 to 1 ng/L upward. None reached that limit, so their total is below 3.4 ng/L rather than zero.

None found. The lab sees nothing below 3.4 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Nouvoitou, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 8 April 2026. The total is below 3.4 ng/L, the sum of the detection limits and 6.8 times our 0.5 ng/L benchmark. Sum of 20 PFAS: 0.52 ng/L (0.0005 µg/L), below the EU legal limit (100 ng/L). Sampled in Acigné, on the same network. 4 checks since 17 June 2025: PFAS-4 up to 3.43 ng/L, sometimes below the detection limit, averaging at least 1.91 ng/L over 12 months (non-detects as 0). No clear trend. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

PFAS over time in Nouvoitou
5 PFAS checks since 27 February 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Nouvoitou.
“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 |
|---|---|---|---|
| < detection limit | 0.52 ng/L | Acigné | |
| 2.56 ng/L | 5.49 ng/L | Châteaubourg | |
| 1.65 ng/L | 8.42 ng/L | Châteaubourg | |
| 3.43 ng/L | 8.42 ng/L | Châteaubourg | |
| < 3.4 ng/L · calculated | < detection limit | Châteaubourg |
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 Nouvoitou safe to drink?
Yes. At the check on 17 June 2026, the tap water in Nouvoitou 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 Nouvoitou's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 0.52 ng/L. The EU limit is 100 ng/L, so this water is at 0.5 % of the limit. (below the EU limit)
Does the water in Nouvoitou 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 3.4 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 Nouvoitou's tap water?
No clear trend. Since 27 February 2025, 4 checks have been published; on the main network the PFAS-4 sum ranged between 1.65 ng/L and 3.43 ng/L (3 quantified values), at times below the detection limit. pfasnearme only reports a trend from a change of at least 25 % and 1 ng/L. These history statistics use laboratory-published sums only.
How hard is the water in Nouvoitou?
The water hardness in Nouvoitou is 12.6 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
