The condition of the water that a person uses at home and for drinking is one of the determining factors for a high quality of life. Water usually enters the faucet to the end user in two ways.

Water from the water supply system may have a yellowish tint, a specific odor, as well as an increased content of hardness salts, less often iron, aluminum, and nitrates. Some impurities can affect the quality of water use in everyday life, and some negatively affect the organoleptic and toxicological qualities of water. 

Well water often has increased hardness and iron content, and can also smell like rotten eggs (hydrogen sulfide). Almost any water requires a certain purification to bring it to a suitable state. Using the water purifier plays an important in the treatment of water for safe healthy consumption.

The composition of the water may differ even within the same locality. If water is taken from a centralized water supply system, the main causes of pollution are:

  • Outdated water treatment equipment that does not cope with the tasks assigned to it; chlorine odor due to excessive chlorination;
  • The general condition of water intake sources and, as a consequence, the content of abnormal amounts of pollutants (usually water enters your tap from one of the reservoirs of your settlement);
  • Color and odor of water as a result of imperfection and old age of pipelines.

If we talk about alternative sources of water, for example, wells, then the following problems arise:

  • Reddish or gray coating on plumbing, metallic taste of water due to the high content of iron and manganese
  • The smell of rotten eggs due to the high content of hydrogen sulfide
  • Sticky coating on surfaces in contact with water, and high color of water – the content of suspended particles and bacteria.
