Drinking water quality in Ardentes
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at 0.0035 µg/L. The EU limit is 0.1 µg/L, so this water is at 3 % of the limit. (22 September 2025)
The four most harmful PFAS add up to 0 µg/L, below the health limit of 0.004 µg/L used in Sweden since 2026.
Substances too small to measure count as 0, so the real total may be higher.

Official assessment
The latest official test failed at least one quality requirement.
„Eau d'alimentation non-conforme à la limite de qualité pour les paramètres nitrate (50 mg/l) et Nitrates/50 + Nitrites/3 (>1 mg/L). Eau non recommandée aux femmes enceintes et aux nourrissons de moins de 6 mois. Les résultats d'analyses de ce prélèvement ont mis en évidence un dépassement de la valeur indicative de 0,9 µg/L sur un métabolite de pesticide non pertinent ESA-Métazachlore.“

Frequently asked questions
Is tap water in Ardentes safe to drink?
The latest official test failed at least one quality requirement.
How high are PFAS levels in Ardentes's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 0.0035 µg/L. The EU limit is 0.1 µg/L, so this water is at 3 % of the limit. (below the EU limit)
Does the water in Ardentes also meet the strictest limits in Europe?
Yes. Even against Europe's strictest limit, the health limit of 0.004 µg/L used in Sweden since 2026, the measured value of 0 µg/L stays below.
How hard is the water in Ardentes?
The water hardness in Ardentes is 13.5 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
