Safe water has the following characteristics:

  • It must be free from pathogenic organisms. Pathogenic organisms are those which cause or capable of causing disease.
  • It must be free from toxic substances.
  • It must be free from excess of minerals and organic matter.
  • It should contain high enough oxygen.
  • It should have a suitable temperature.
  • Divalent ions such as calcium ions should not be present in the water as they make the water hard and makes it unfit for drinking.
  • The allowable ph range should be 6.5-8.5 to control undesirable chemical reactions.
