Many water treatment plants use a combination of coagulation, sedimentation, filtration and disinfection to provide clean, safe drinking water to the public. Worldwide, a combination of coagulation, sedimentation and filtration is the most widely applied water treatment technology, and has been used since the early 20th century.
But many people in developing countries, and people living in rural areas of developed countries (including many First Nations communities) do not take safe drinking water for granted. They understand the relationship that exists between safe drinking water and good health, because they have experienced waterborne disease firsthand.
Water temperature is critical because it is an important quality in environmental parameters. It is important to measure water temperature. By doing so, we can see the characteristics of the water such as the chemical, biological, and physical properties of the water, as well as the possible health effects.
