Hardness, nitrates, pH, sanitary compliance: the real tap water quality in Gourbeyre (soft water), with official Hub'Eau data updated monthly.
⚠ Non-compliance detectedAt 10.2°f, water in Gourbeyre is classified as soft — a favourable level for daily maintenance. White deposits on taps and shower walls are limited; monthly white vinegar treatment is generally enough to keep fixtures clean. For heating appliances, annual descaling is sufficient, compared to two or three times per year in hard water areas. Official sanitary tests report a non-compliance on at least one monitored parameter: see the details below.

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: ~£29/year
For 2 persons, water at 10.2°f deposits around 0.5 kg of limescale per year in your appliances. Estimated cost in descalers, salt and filters.
Calcium: ~16 mg per litre
Your water provides 16 mg of calcium/L, which is 2% of the recommended daily intake.
Filtration not required
Your soft water does not require filtration. A jug filter remains useful for taste.

Little. At 10.2°f, water in Gourbeyre is soft: limescale deposits remain limited on taps, shower walls and heating appliances.
No. With soft water (10.2°f), a softener would bring nothing: limescale isn't the issue in Gourbeyre.
The last available official sanitary analysis (30 June 2026) reports a non-compliance on at least one parameter. The affected parameter and any usage restrictions are in the official report: contact your water distributor or regional health agency (ARS) for details.
