Most dangerous drinking water contaminants impurities

Most people worry about germs in water which can cause water-borne diseases like dysentery, cholera, etc. These are terrible diseases, but can easily be cured with modern day antibiotic medicines. Simply by boiling water will kill all germs in water.

Much more dangerous than any germ or virus or parasite in water, is if the water contains dissolved chemicals, especially the salts of Heavy Metals like Arsenic, Chromium-6, Lead, Mercury, etc. which can cause lifelong damage and early death. You may not even know that you are being slowly poisoned with heavy metal contamination of drinking water because there is no taste or smell in the water. Heavy metals in water can only be detected by chemical analysis of water.

Why dissolved 'Heavy Metals' in water are so dangerous, is because when water with even a small trace of heavy metal is drunk over a long period of time, it can cause problems. Heavy Metal chemicals in drinking water 'bio-accumulate' in our body, which means that once heavy metal is absorbed, our body cannot get rid of it. So even though there are no immediate problems, the heavy metals in our body keep on accumulating as you drink more and more water daily. Finally the day will come when Heavy Metal poisoning symptoms start showing. By then it is usually too late.

Heavy metals in water cause cancer, stunted growth, nerve damage, and early death. Children suffer most from the heavy metal pollution of water. Boiling water does not, we repeat, does 'NOT' remove Arsenic and other heavy metals and dissolved salts from water.

Corporation or Municipal water is usually free from Heavy Metals. Well water in many areas do not have Heavy metals. But this does not rule out the possibility of Heavy Metal contamination in our drinking water. Water being the universal solvent that it is, can leach out Heavy Metals from anything it comes in contact with, for example, water tanks and pipelines which may contain heavy metal. As mentioned before, even if the water contains a just very small trace of heavy metals, it will be absorbed by our body, and it continues to stay in our system, because our Kidneys and other organs cannot get rid of it from our body. .....More from our page about the danger and harmful health effects of Heavy Metals in Drinking Water.

Some say that because RO water purifier removes everything, including any essential minerals the water may contain, it is not good.
