Water is billions of years old and has been through all kinds of stuff: from purity of Himalayas to garbage laden dirty drains, as fluids inside the bodies of plants& animals to dirty excretions, vomiting of extremely sick patients.....
Yes, it was the same water!
Water has been recycled innumerable times by nature's wonderfully magnificent recycling process and used over and over and over again.
Each recycle rendered it fresh , pure, drinkable , unaffected by all dirty poisonous materials which had floated in it for long duration.
Such is the most amazing and robust engineering-technology of our Universe, a creation of the greatest scientist, the Almighty!
