PFAS in Saint-Georges-sur-Eure's tap water: 5 ng/L, 10x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
10× 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.
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).

In Saint-Georges-sur-Eure, the 4 most closely watched PFAS (PFAS-4) add up to 5 ng/L (0.005 µg/L) at the latest PFAS check on 8 January 2026. That's 10 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 9 ng/L (0.009 µg/L), below the EU legal limit (100 ng/L). 2 checks since 4 June 2025: sum of 20 PFAS from 6 ng/L to 9 ng/L.

PFAS over time in Saint-Georges-sur-Eure
2 PFAS checks since 4 June 2025, from the published measurements.
“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 |
|---|---|---|
| 5 ng/L – < 7 ng/L · calculated | 9 ng/L | |
| 4 ng/L – < 6 ng/L · calculated | 6 ng/L |
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 Saint-Georges-sur-Eure safe to drink?
At the latest check, the water was over at least one limit. “Eau de qualité chimique non conforme en raison du dépassement de la limite de qualité en vigueur pour le paramètre chlorothalonil SA (R417888) et de la valeur indicative de 0,9 µg/L pour le chlorothalonil R471811. Ces non-conformités n’entrainent pas de restriction de consommation de l’eau d’après l’expertise de l’Agence Nationale de Sécurité Sanitaire de l'Alimentation, de l'Environnement et du Travail (ANSES). Un suiv i renforcé est mis en place pour le Chlorothalonil SA. Cette situation nécessite de mettre en œuvre un plan d'actions afin de rétablir la qu alité de l'eau.”
How high are PFAS levels in Saint-Georges-sur-Eure's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 9 ng/L. The EU limit is 100 ng/L, so this water is at 9 % of the limit. (below the EU limit)
Does the water in Saint-Georges-sur-Eure also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 5 ng/L. That is 1.25 times Sweden's legal limit of 4 ng/L, in force since 2026. Germany will set a similar one in 2028. The water still passes the current EU legal limit (100 ng/L for the total of 20 PFAS).
Are PFAS levels rising in Saint-Georges-sur-Eure's tap water?
Calculated PFAS-4 values are listed in the table. The chart uses laboratory-published sum-of-20 results; there are too few laboratory-published PFAS-4 sums for the existing trend calculation.
How hard is the water in Saint-Georges-sur-Eure?
The water hardness in Saint-Georges-sur-Eure is 22.8 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
