Water is a basic need and without it we wouldn’t be able to survive. We use it for our everyday life and most of all, it is what we drink. However, the environment has gone so dirty that rivers and our other sources of water for drinking are getting contaminated everyday. As you open your faucet to drink tap water, you will notice that the water is not as clear as before. You can see some particles on the water that proves its contamination. You see, the water pipes are not clean and safe. The very source of the water itself is not safe either. Because of this, gastrointestinal diseases are becoming rampant. We can’t rely on freshwater anymore but resort to purified water.
