Hardness, nitrates, pH, sanitary compliance: the real tap water quality in Tallard (very hard water), with official Hub'Eau data updated monthly.
⚠ Non-compliance detectedTap water in Tallard reaches 38.8°f — "very hard" category. This high limescale level requires an active maintenance strategy: monthly tap descaling, weekly shower wall cleaning and semi-annual appliance filter checks. Sanitary water quality remains compliant; managing limescale and protecting installations is the real daily challenge. 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: ~£109/year
For 2 persons, water at 38.8°f deposits around 1.9 kg of limescale per year in your appliances. Estimated cost in descalers, salt and filters.
Calcium: ~62 mg per litre
Your water provides 62 mg of calcium/L, which is 6% of the recommended daily intake.
Filter jug: cartridge every 3 months
At 38.8°f, replace the cartridge every 3 months. An under-sink filter lasts 6 to 12 months.

Tallard ranks 5th out of 10 cities in the department in our database.
Tap water in Tallard has a quality index of 7.2/10 (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 Tallard is 38.8°f (French degrees), making it very hard water. The average is 23.6°f in the Hautes-Alpes department and 22.1°f across our entire database.
Yes, significantly. At 38.8°f, water in Tallard is very hard: limescale deposits rapidly on all water-contact surfaces and heating appliances.
It may be justified. At 38.8°f, water in Tallard is very hard: a softener limits scale build-up in pipes and heating appliances, worth comparing with simple antiscale maintenance depending on daily inconvenience.
The last available official sanitary analysis (9 June 2026) reports a non-compliance on at least one parameter. Official conclusion: "Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés." The affected parameter and any usage restrictions are in the official report: contact your water distributor or regional health agency (ARS) for details.
The pH measured in Tallard is 7.3. Regulations require a value between 6.5 and 9: the water is within this range.
