Most consumers believe that the water they have coming from their faucets is properly filtered by the water company. They are completely unaware of what is in our drinking water, and do not realize that the filtration used on the drinking water system at most water processing plants does not remove any of these harmful chemicals. Most water processing plants still use an old fashioned form of filtration that is nothing more than a process that removes visible debris from the water. They then use chlorine bleach to make the water clear.
