What process used to make polluted water drinkable?

Answer 1

I guess you could boil it, or use iodizing pills that will mix into the water to clean it. Maybe bleach? but i have no idea the correct method :S

16 drops of bleach (about 0.8 ml) per gallon of water mixed and left to stand for 20 min should render it drinkable as far as bacteria goes (it won't do anything for chemicals).
