Water is our source of life and very vital to healthy living. We need water to transport nutrients to our body organs, maintain body temperature, flush out our toxins and much more. Water improves our muscle tone and we definitely look good. Having the ability to perform so many tasks in the human body it is rightly called as the elixir of life. But water can easily be contaminated. Since most of us depend on wells or reservoirs for drinking water, it is highly recommended to boil and drink. Underground well water is untreated and may contain hazardous industrial wastes and pesticides, heavy metal and microbiological contaminants. If consumed over a long period of time they could damage our organs. Contaminated water can cause typhoid, hepatitis, diarrhea, dysentery and gastroenteritis. Water has to be purified by filtering, straining and boiling. There are a lot of equipments that are now available in the market and the manufacturers claim that it can make water pure to about 99%. But there are a couple of people who can make hoax just to cash in and it is up to us to make sure that our families are protected well. The best thing to do would be to be less dependent on the external purifiers and just have the water boiled. It also goes easy on the pocket.
