Wait...you mean that rotten egg smell is not normal?!
Yeah, its not the best tasting water out of the tap and I pray that the water filter I use catches most of chemicals used to purify the water as I remember that they had switched the chlorination method to something else thats more eco friendly.
Either way no matter where you go potable water is going to be a problem as more demands are placed on systems around the world. Between run off, purification of chemicals in the water before treatment, and of course waste by products, I wouldn't say this is a Indian Land exclusive issue.
