We drink it; cook with it; bathe in it; wash our clothes in it, and brush our teeth with it every day, without giving too much thought to the processes that water goes through to reach our homes in a form pure enough for human consumption.
Most local water is treated commercially by a water treatment facility. Water purification is the removal of contaminants from untreated water to produce clean consumable water for homes, hospitals, and chemical or manufacturing plants. Water may be treated differently in different locations depending on the quality of the water that enters the treatment plant. For example, groundwater typically requires less treatment than water from lakes, rivers, and streams.
Drinking water quality standards are set by governments or by international standards which set minimum and maximum concentrations of contaminants for each intended use. World Health Organization (WHO) guidelines are generally followed throughout the world for drinking water quality requirements. In addition, each country, state, or region can have their own guidelines, based on location, in order for consumers to have access to safe drinking water.
