Water quality is important for human health

A water supply system typically collects water from rivers, reservoirs or groundwater aquifers. Even industrially purified water can still contain impurities — and even toxins — that get into the water as a result of human activities.

If you are concerned about water quality:

  • Have the water tested at a specialist laboratory. Such services are often provided by a centre for hygiene and epidemiology.
  • Improve your drinking water by using a filter appropriate to the type of water you have at home.
  • Let tap water sit for a couple hours or so before giving it to pets or watering your houseplants.
  • Drink bottled or boiled water. In many cities, it is recommended not to drink non-boiled tap water. More and more people are using filters or buying water in bottles.
