PFAS in Tronget's tap water: 1 ng/L, 2x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
2× above our health benchmark
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 Souvigny, on the same distribution network as Tronget (RESEAU RIVE GAUCHE ALLIER). 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.
Substances below the detection limit count as 0, so the real total may be higher.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).
More PFAS than in 82% of the cities we track

In Tronget, the 4 most closely watched PFAS (PFAS-4) add up to 1 ng/L (0.001 µg/L) at the latest PFAS check on 16 February 2026. That's 2 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 1 ng/L (0.001 µg/L), below the EU legal limit (100 ng/L). Sampled in Souvigny, on the same network. 3 checks since 16 July 2025: PFAS-4 up to 2 ng/L, sometimes below the detection limit, averaging at least 1 ng/L over 12 months (non-detects as 0).

Details and sources
PFAS over time in Tronget
4 PFAS checks since 11 March 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Tronget.
“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 |
|---|---|---|---|
| 1 ng/L | 1 ng/L | Souvigny | |
| 2 ng/L | 2 ng/L | Verneuil-en-Bourbonnais | |
| < 20 ng/L | < 29 ng/L | Verneuil-en-Bourbonnais | |
| < 4 ng/L · calculated | < 100 ng/L | Verneuil-en-Bourbonnais |
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 Tronget safe to drink?
Yes. At the check on 24 March 2026, the tap water in Tronget was within every limit tested. “Eau conforme aux limites et aux références de qualité pour ce qui concerne les paramètres mesurés.”
How high are PFAS levels in Tronget's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 1 ng/L. The EU limit is 100 ng/L, so this water is at 1 % of the limit. (below the EU limit)
Does the water in Tronget also meet the strictest limits in Europe?
Yes. Even against Europe's strictest legal limit, Sweden's 4 ng/L in force since 2026, the measured value of 1 ng/L stays below.
Are PFAS levels rising in Tronget's tap water?
Too few quantified checks to say (2 since 11 March 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 Tronget?
The water hardness in Tronget is 14 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 12 September 2026.
Same water network
Same distribution network as Tronget, so in principle the same water.
