Chlorine is an excellent chemical for killing bacteria and microbes that grow in water. Solutions are added at Water Treatment facilities to slowly release the chemical into the water supply. The levels are high enough to kill the bacteria but low enough as to not cause harm during human consumption.
What are the advantages and disadvantages of chlorination?
Advantages: Chlorination of water from a catchment free of encysting organisms produces reliably safe drinking water. Residual chlorine levels allows water to remain safe from pathogens that could contaminate it downstream of the treatment plant.
