Hardness, nitrates, pH, sanitary compliance: the real tap water quality in Capesterre-Belle-Eau (very soft water), with official Hub'Eau data updated monthly.
✓ Compliant with sanitary standardsCapesterre-Belle-Eau (Guadeloupe) stands out with particularly soft water: 4.1°f. Households use far fewer descaling products and water heaters maintain their efficiency longer. With such low mineralisation, some prefer a remineralisation filter to restore a more balanced taste at the tap. 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: ~£11/year
For 2 persons, water at 4.1°f deposits around 0.2 kg of limescale per year in your appliances. Estimated cost in descalers, salt and filters.
Calcium: ~7 mg per litre
Your water provides 7 mg of calcium/L, which is 1% of the recommended daily intake.
Filtration not required
Your soft water does not require filtration. A jug filter remains useful for taste.

Tap water hardness in Capesterre-Belle-Eau is 4.1°f (French degrees), making it very soft water. The average is 8.9°f in the Guadeloupe department and 22.1°f across our entire database.
Very little. At 4.1°f, water in Capesterre-Belle-Eau is very soft: limescale deposits remain minimal on taps, shower walls and heating appliances.
No. With very soft water (4.1°f), a softener would bring nothing: limescale isn't the issue in Capesterre-Belle-Eau.
Yes. In the last available official sanitary analysis (2 April 2026), water distributed in Capesterre-Belle-Eau was declared compliant, meaning it can be drunk directly from the tap. This is a point-in-time sample, not real-time monitoring.
