Water Purification and Quality


Summary. Adequate daily intake of water is essential for the proper and effective functioning of the body.

Importance of Water. The human body is composed of about 60% water with vital organs needing more water to function properly. According to the United States Geological Survey (USGS), “… the brain is composed of 70 percent water, and the lungs are nearly 90 percent water. About 83 percent of our blood is water, which helps digest our food, transport waste, and control body temperature. Each day humans must replace 2.4 litres of water, some through drinking and the rest taken by the body from the foods eaten.” For this reason it is essential to consume enough water every day.

Importance of Clean Water. Because water touches on every aspect of the body, it is important to have a pure source of water that is preferably an economical one. Countertop filtration systems (example) are inexpensive and generally effective to deliver water that is clean and tastes good. For anyone desiring higher quality filtered water, most larger grocery stores now offer high quality water filtration systems for refilling your water containers at about 25 to 30 cents per gallon.
