      Hello! Our drinking water can be treated in a few different ways to make it safe to drink…

      Chemicals can be added to make all the dirt stick together (coagulation). Then the dirty bits sink to the bottom (sedimentation) leaving the water to move through a filter which will catch any tiny bits floating in it (filtration). Next chemicals like chlorine can be added to kill bacteria, fungi etc (disinfection).

      Or if you are out in the wild with only a pan and a campfire, the best thing to do to make the water safe to drink is boil it!
