Hardness, nitrates, pH, sanitary compliance: the real tap water quality in Magné (hard water), with official Hub'Eau data updated monthly.
✓ Compliant with sanitary standardsIn Magné, water hardness at 26.7°f indicates hard water, typical of French limestone areas. Scale quickly forms in pipes, showerheads and thermal appliances, reducing their efficiency and lifespan. Hard water is not a health risk; equipment wear and increased household product consumption are the main downsides. 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.
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: ~£75/year
For 2 persons, water at 26.7°f deposits around 1.3 kg of limescale per year in your appliances. Estimated cost in descalers, salt and filters.
Calcium: ~43 mg per litre
Your water provides 43 mg of calcium/L, which is 4% of the recommended daily intake.
Filter jug: cartridge every 4 months
At 26.7°f, replace the cartridge every 4 months. An under-sink filter lasts 6 to 12 months.

Top 10 cities in the Deux-Sèvres department ranked by tap water quality in our database.
Magné ranks 19th out of 30 cities in the department in our database.
Tap water in Magné has a quality index of 5.2/10 (average 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 Magné is 26.7°f (French degrees), making it hard water. The average is 21.9°f in the Deux-Sèvres department and 22.1°f across our entire database.
Yes. At 26.7°f, water in Magné is hard: limescale deposits quickly on taps, shower walls and heating appliances.
It may be justified. At 26.7°f, water in Magné 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 (27 February 2026), water distributed in Magné 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 Magné is 7.2. Regulations require a value between 6.5 and 9: the water is within this range.
Compare tap water quality in other cities of the Deux-Sèvres 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.
