Note: The methodology used in the Global Open Data Index has changed over time; significantly so between 2015 and 2016. For this reason, the results are not directly comparable over time.

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

How open is the data?

There isn't a lot of water quality data but reports and references to water quality of environmental sources. Drinking water is decentralized and there doesn't seem to be a strong central management of water quality.

Your submission is valid. Thank you very much for contributing to the Global Open Data Index.
