Cities / Dordogne / Boulazac Isle Manoire

What this means in practice

At 28.6°f, water in Boulazac Isle Manoire (Dordogne) is classified as hard — a high limescale risk zone. Appliances (washing machines, dishwashers, water heaters) see reduced efficiency and lifespan if hardness isn't compensated. A water softener, or at minimum regular antiscale tablets and large amounts of regenerating salt, becomes necessary in the long term. Official sanitary tests declare it compliant with current standards across all monitored parameters.

Full water analysis for Boulazac Isle Manoire

Results from the latest official sanitary samples (Hub’Eau, French Ministry of Health). Click a card to understand what each parameter measures.

Sanitary complianceCompliantNo anomalyDetail

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.

Limescale (TH)28.6°fhardDetail

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.

Nitrates5.4mg/LLow levelDetail

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.

PFAS0µg/LBelow thresholdDetail

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.

pH7.4Within rangeDetail

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 chlorine0.5mg/LPerceptible tasteDetail

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.

Turbidity0NFUExcellent clarityDetail

Turbidity measures water clarity, in NTU (nephelometric turbidity units). A low value indicates clear water with few suspended particles.

Conductivity528µS/cmMineralisationDetail

Conductivity reflects overall water mineralisation, in µS/cm. It has no strict sanitary threshold but indicates the dissolved mineral salt content.

Impact on my home

People in household:

Maintenance budget: ~£80/year

For 2 persons, water at 28.6°f deposits around 1.4 kg of limescale per year in your appliances. Estimated cost in descalers, salt and filters.

Calcium: ~46 mg per litre

Your water provides 46 mg of calcium/L, which is 5% of the recommended daily intake.

Filter jug: cartridge every 4 months

At 28.6°f, replace the cartridge every 4 months. An under-sink filter lasts 6 to 12 months.
