Chlorine is added to drinking water to disinfect the water and make it suitable for human consumption. This has had a huge part to play in preventing diseases like cholera. However, there is also some concern that chlorine may form carcinogenic(cancer causing) compounds in water and may be toxic to humans and the environment.

1. How effective is chlorine in preventing cholera?
2. Brief history on the use of chlorine as a disinfectant in drinking water?
3. How safe is our drinking water?

Please help!
thank you xx
