Dureza del agua en Valencia

Especificaciones Técnicas del Agua

Según los datos actuales de calidad del agua proporcionados por EMIVASA, la dureza del agua medida en Valencia es de 276 mg/L (aproximadamente 15.5 °dH), lo que se clasifica oficialmente como Muy Dura bajo las directrices hidroquímicas europeas.

Valencia draws from the Júcar River (Mancha Oriental aquifer system), managed by EMIVASA. The river traverses the calcareous La Mancha plateau before reaching Valencia, accumulating very high mineral loads — making Valencia one of the hardest water cities in Western Europe.

Análisis Geológico y de Infraestructura

  • Clasificación de Percentil: Valencia ranks in the top 20% of measured municipalities nationally for mineral density.
  • Factor Geológico: The local municipal supply (managed by EMIVASA) yields a base hardness of 276 mg/L. Seasonal variation of ±5–10% is typical in regions with mixed surface/groundwater sourcing.
  • Nota de Infraestructura: Given the infrastructure age typical of urban centers of this size, localized pipe scaling may compound these base metrics at the tap.

Data Transparency: How We Calculate Hardness

The hardness data presented for Valencia is aggregated from local municipal water reports, user-submitted tests, and regional hydro-geological surveys. Because water hardness fluctuates seasonally based on rainfall and reservoir levels, our displayed mg/L is an annualized average estimate.

  • Update Frequency: Bi-annually
  • Measurement Standard: Milligrams per liter (mg/L) equivalent to ppm.

Household Soap & Detergent Efficiency

For the 1,800,000 residents in the greater Valencia metropolitan area, water is typically sourced and treated by large-scale facilities like EMIVASA. At an exceptionally high measurement of 276 mg/L, the calcium and magnesium concentration severely restricts how soaps and detergents dissolve. Residents will typically experience immediate mineral scaling on fixtures and a total lack of lather efficiency. In dense urban grids like Valencia, compounding pipe scaling means you may need significantly more detergent and specialized rinse aids to overcome the base 276 mg/L resistance.

Informational Notice: The above data relates strictly to the physical and chemical interaction between mineralized water and standard household cleaning agents. It is aggregated from public municipal water quality reports and is provided for educational comparison only.

About This Data

This hardness value represents the most recent verified measurement from EMIVASA. Municipal water hardness is reviewed bi-annually. Seasonal variation of ±5–10 mg/L is typical in regions with mixed surface/groundwater sourcing.

Hard Water & Skin Health in Valencia

Eczema & Skin Sensitivity

A 2021 study by King's College London found that hard water above 150 mg/L significantly increases the likelihood of eczema flares by damaging the skin barrier. At 276 mg/L, Valencia's water exceeds this threshold. Residents with sensitive skin or eczema are advised to consider a shower filter.

Hair & Scalp Damage

Calcium and magnesium ions above 200 mg/L bind to hair proteins, increasing friction and reducing tensile strength. This accelerates colour fade in treated hair and can worsen scalp dryness. A chelating shampoo or shower softener can reduce mineral deposition by up to 80%.
