Water Quality 85% open


What data is expected?

Data, measured at the water source, on the quality of water is essential for both the delivery of services and the prevention of diseases. The Index either looks at the quality of designated drinking water sources, or of environmental water sources (if drinking water data is not available). See our methodology for more information. In order to satisfy the minimum requirements for this category, data should be available on level of the following chemicals by water source.

  • Fecal coliform
  • Arsenic
  • Fluoride levels
  • Nitrates
  • Total Dissolved Solids
  • Data per water source
  • Available for entire country
