Water treatment is a method used to make water more tolerable for a desired end-use, including the treatment for drinking water. The goal is to remove existing components which are found inside the water to improve it for subsequent utilization.
The population of the US, which has tripled since the early 20th century, is projected to surge another 50% in the next 50 years. Besides, the country's urban use of land has even more than tripled since the middle of the 20th century. As more land is paved over for roads, buildings, malls etc. there is less open space for rain to soak into the earth to become groundwater.
This inexorable development makes underground aquifers unable to replenish themselves properly, which, of course, has implications on our drinking water (almost half of our water comes from aquifers; most of the rest from reservoirs, rivers and lakes). As a result, as water levels drop, the water that is left on Earth becomes costlier to pump and treat (as it is deeper and contains more salt).
Another problem we have to face is the age of our water distribution pipes and treatment plants. "Almost every source of drinking water in the United States is at higher risk today than 50 years ago," an Environmental Protection Agency's water administrator said. The pipes are old and costly to replace and can support microbiological bacteria to grow. Above that they are prone to breakage and often contain lead, thus leaching it into the municipal water supply.
Many municipal water utilities still treat water using technologies developed before World War II, according to a report by the Natural Resources Defense Council, an environmental group. The water treatment facilities add substances to the water that can increases risks of disease for the people who drink the water. For many years, until today, they add Chlorine, Fluoride, Ammoniac and many more chemicals to the water supply, to disinfect and "clean" the water.
Needless to say, there is an ongoing debate among the various groups interested in safe drinking water, concerning the water pollution, its costs, and the risks of every aspect of the water treatment and distribution business.
The safest choice to decrease the risk of disease and illness from contaminants in tap water is to use an effective Water Filtration Systems to purify the water in your home.
