Hardness, nitrates, pH, sanitary compliance: the real tap water quality in La Ville-aux-Dames (hard water), with official Hub'Eau data updated monthly.
✓ Compliant with sanitary standardsAt 30.5°f, water in La Ville-aux-Dames (Indre-et-Loire) is classified as hard — a high limescale risk zone. Appliances (washing machines, dishwashers, water heaters) see reduced efficiency and lifespan if hardness isn't compensated. A water softener, or at minimum regular antiscale tablets and large amounts of regenerating salt, becomes necessary in the long term. Official sanitary tests declare it compliant with current standards across all monitored parameters.

Sanitary compliance summarises adherence to French regulatory limits across all analysed parameters (bacteriology, chemistry, radioactivity). Compliant water can be consumed directly from the tap without additional treatment.
The TH (titre hydrotimétrique) measures calcium and magnesium concentration, expressed in French degrees (°f). The higher it is, the harder the water and the faster limescale deposits on surfaces and in appliances.
Nitrates come mainly from agriculture and waste water. The French regulatory limit is 50 mg/L; below 25 mg/L, the level is considered low.
PFAS are persistent chemical compounds, sometimes called "forever chemicals", used in industry. The vigilance threshold used here is 0.1 µg/L, consistent with current health recommendations.
pH measures water acidity. Regulations require a value between 6.5 and 9: outside this range, water may encourage pipe corrosion or affect taste.
Free chlorine is added to disinfect water and prevent bacterial growth in the distribution network. High levels can produce a perceptible taste or odour, without health risk at authorised levels.
Turbidity measures water clarity, in NTU (nephelometric turbidity units). A low value indicates clear water with few suspended particles.
Conductivity reflects overall water mineralisation, in µS/cm. It has no strict sanitary threshold but indicates the dissolved mineral salt content.
Maintenance budget: ~£85/year
For 2 persons, water at 30.5°f deposits around 1.5 kg of limescale per year in your appliances. Estimated cost in descalers, salt and filters.
Calcium: ~49 mg per litre
Your water provides 49 mg of calcium/L, which is 5% of the recommended daily intake.
Filter jug: cartridge every 4 months
At 30.5°f, replace the cartridge every 4 months. An under-sink filter lasts 6 to 12 months.

Tap water hardness in La Ville-aux-Dames is 30.5°f (French degrees), making it hard water. The average is 21.6°f in the Indre-et-Loire department and 22.1°f across our entire database.
Yes. At 30.5°f, water in La Ville-aux-Dames is hard: limescale deposits quickly on taps, shower walls and heating appliances.
It may be justified. At 30.5°f, water in La Ville-aux-Dames is hard: a softener limits scale build-up in pipes and heating appliances, worth comparing with simple antiscale maintenance depending on daily inconvenience.
Yes. In the last available official sanitary analysis (10 June 2026), water distributed in La Ville-aux-Dames was declared compliant, meaning it can be drunk directly from the tap. Official conclusion: "Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés." This is a point-in-time sample, not real-time monitoring.
The pH measured in La Ville-aux-Dames is 7.1. Regulations require a value between 6.5 and 9: the water is within this range.
