Why Purify Water?

why-treat-waterAny time you are concerned with water quality you should treat the water before consuming. In normal circumstances, municipal water in the United States and most developed countries is perfectly safe to drink. However, there are times when water quality cannot be trusted and treatment is strongly advised:

  • Water straight from natural sources such as rivers, streams or lakes. Water may be contaminated by runoff from surrounding lands.
  • Water from the tap when the water supply has been jeopardized by natural disasters such as floods, hurricanes, tornadoes or earthquakes. Physical breaches can allow external contaminants into enclosed water systems and power outages can disrupt water pumping stations, allowing water pressure to slow or become stagnant, creating risk of microbial contamination.
  • If local authorities announce a boil water advisory alert.
  • When traveling to foreign countries with questionable water quality, especially Latin America, Asia, the Middle East and Africa.

In each of the situations listed above, there is the potential presence of a variety of microorganisms such as bacteria, viruses, protozoa, including giardia and cryptosporidium. These microbes make you sick by reproducing quickly and overwhelming your body’s immune system. For a list of common microbes that can cause waterborne illnesses click here.
