Hardness, nitrates, pH, sanitary compliance: the real tap water quality in Mende (hard water), with official Hub'Eau data updated monthly.
✓ Compliant with sanitary standardsMende has particularly mineral-rich water: 31°f — a high level exceeding the national average. White deposits on stainless steel and chrome surfaces form quickly; bi-monthly descaling and regular filter maintenance are essential. The most effective long-term solution is installing a softener on the main water supply. 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: ~£87/year
For 2 persons, water at 31°f deposits around 1.5 kg of limescale per year in your appliances. Estimated cost in descalers, salt and filters.
Calcium: ~50 mg per litre
Your water provides 50 mg of calcium/L, which is 5% of the recommended daily intake.
Filter jug: cartridge every 4 months
At 31°f, replace the cartridge every 4 months. An under-sink filter lasts 6 to 12 months.

Top 5 cities in the Lozère department ranked by tap water quality in our database.
Mende ranks 4th out of 5 cities in the department in our database.
Tap water in Mende has a quality index of 6/10 (good quality) in our database, calculated on nitrates, PFAS, pH, free chlorine and turbidity. This is a comparative reading of Hub'Eau data, not an official rating.
Tap water hardness in Mende is 31°f (French degrees), making it hard water. The average is 10.3°f in the Lozère department and 22.1°f across our entire database.
Yes. At 31°f, water in Mende is hard: limescale deposits quickly on taps, shower walls and heating appliances.
It may be justified. At 31°f, water in Mende 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 (1 June 2026), water distributed in Mende 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 Mende is 7.8. Regulations require a value between 6.5 and 9: the water is within this range.
Compare tap water quality in other cities of the Lozère department, ranked by quality index.
Methodology: the quality index compares each city against the 4806 other cities in our database on 5 parameters (nitrates, PFAS, pH, free chlorine, turbidity) and averages its relative position on each. This is not an official rating, only a simplified comparative reading of Hub’Eau data.
