Water Treatment

In cities, water is treated before it come to your houses. Our water comes from wells undergrounds, then the water is treated with chlorine, iron is removed, and fluoride is added (  http://www.ci.eaton-rapids.mi.us/documents/2009CCR_000.pdf  ). Water is treated with chlorine to remove pollinates like viruses/bacterias, oils, gases, and other chemicals in the water. And fluoride is added for dental benefits. This is how water is treated. Sewer water is also treated before it put back in the rivers. They need to do this because chemicals from the road (like oil) and other chemicals would have a harmful affect on the Eco system.

Why is chlorine added to the water?

What is removed from the water?
