Hardness, nitrates, pH, sanitary compliance: the real tap water quality in Tourrettes-sur-Loup (moderately hard water), with official Hub'Eau data updated monthly.
✓ Compliant with sanitary standardsAt 21.1°f, tap water in Tourrettes-sur-Loup is moderately hard — the most common level in France. Limescale traces gradually appear on taps and shower walls, but maintenance remains manageable with an antiscale product every two to three weeks. Appliances work without major issues; semi-annual descaling of the kettle and steam iron is generally sufficient. 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: ~£59/year
For 2 persons, water at 21.1°f deposits around 1.0 kg of limescale per year in your appliances. Estimated cost in descalers, salt and filters.
Calcium: ~34 mg per litre
Your water provides 34 mg of calcium/L, which is 3% of the recommended daily intake.
Filter jug: cartridge every 6 months
At 21.1°f, replace the cartridge every 6 months. An under-sink filter lasts 6 to 12 months.
