Water is the chemical compound of two hydrogen atoms and one oxygen atom. The chemical formula for water is H2O. Water is one of the simplest and most widespread substances in nature, whose physical and chemical properties are well known. Some of these features are unique making water that important for maintaining life on Earth.
Earth is often called blue planet because more than 70% of its surface is covered with water. Furthermore, the human body consists of 60-70% of water and simply can’t live without it. Reducing water in the body by only 2 percent can cause signs of dehydration, short-term memory loss, and concentration problems. This is why March 22 every year is marked as World Water Day. The idea is to draw attention to water and water resources around the world that day.
Where there is Water, there is Life
There simply is no life without water. Also, the quality of water must suit the demands of human health. Therefore it is highly important to protect tap water quality. The quality of water depends on the state of physical, chemical and biochemical features. It depends on the amount of oxygen, nitrate, phosphate, manganese, magnesium and heavy metals.
Rising Population Causes Water Pollution
The rising population and their concentration in large cities caused the amount of organic waste water to increase considerably. The U.S. provides one of the cleanest tap water on planet earth. It is safe from microbes and chemicals – at least that’s what you think.
The tap water of nearly 290 million Americans is provided by community water systems monitored and regulated by the U.S. Environmental Protection Agency. Some public systems deliver a more pure product than others. Protecting tap water quality means fighting two interconnected battles: one against pollution and one against polluted water when it arrives at a treatment plant.
A typical water treatment plant uses the following five steps to clean water before delivering it to customers:
All of these processes help to eliminate contaminants in the water, like shigella, E. coli, and cryptosporidium. However, according to an analysis by the Environmental Working Group, testing by water utilities has found 315 pollutants in America’s tap water. Some of the contaminants as trihalomethanes or copper may cause health problems such as gastrointestinal illness and neurological disorders.
Therefore the time has come to get active and test the water quality in your home or your company and take the right precautions to improve the quality, if necessary.
