    The cheapest way to purify drinking water of natural contaminants is to simply boil it. Boiling water removes the harmful bacteria and other microorganisms that can cause disease and illness. Adding an agent like bleach or iodine is also another cheap way to purify water, but all three of these methods cannot remove toxic components like heavy metals which can be a side effect of many industrial production schemes.
