Water is the most important resource of life on Earth. Human needs about 2 liters of water per day, where 20% of that comes from our food. Should we get the rest of that from bottled water or tap water? Today, the answer is quite obvious since everyone is talking about how harmful bottled water can be to our health. But, is tap water really safer?
It is proved that bottled water can contain bacteria a couple of days after open it and reusing plastic bottles can release the chemical substances from the bottles themselves. Well, those are just simple common senses; tap water can also be as dirty as bottled water. If you leave tap water outside for weeks, it'll grow bacteria. If you reuse disposable tableware, you'll eat the released chemical of the plastic. Furthermore, it is know that purification system can stop working properly, but remains on function. That means, the wastewater that you just flushed away we'll come back to you without even been purified.
We are rejecting more and more contaminants in water; such as medications, drugs, cleaning products, paint, toxic material, etc. Some of the contaminants can't be completely removed by purification systems. However, it doesn't make bottled water better. A study of the United-States' Natural Resources Defense Council show that one third of bottled water* contains contaminants and a quarter was bottled tap water.
Tap water contains another chemical substance that the government added purposely; fluoride. Water fluoridation was an idea for reducing tooth decade. Yet, regular consummation of fluoride can cause yellow tooth. Fluoride can also cause several side effects; such as bone fractures, bone diseases and fluorine poisoning (nausea, vomiting, and diarrhea).
So, is the only safest water come from some brand of bottled water? The answer stays unknown. In today's century, human can do anything to satisfy their desire. Who knows what they might put in their products? The only way to assure your safety is to learn the correct way to purify water by yourself.
* The NRDC's study included testing of more than 1,000 bottles of 103 brands of bottled water.
