What happens if you boil water for too long?

Can fluoride be removed by boiling water?
Distillation
Distillation is an effective and affordable method to remove fluoride from water. As the water is heated, the steam evaporates from the boiling water, where it is captured in another container. This process leaves the fluoride and other contaminants behind.
Can bacteria survive in boiling water?
Boiling water kills or inactivates viruses, bacteria, protozoa and other pathogens by using heat to damage structural components and disrupt essential life processes (e.g. denature proteins).
