We have never gotten sick from well water and have been drinking it for 45 years. I don't buy bottled water unless we are on vacation out of the country, and one location in the US where the chlorine taste was excessive(to my palate).
Our refrigerator has a filter that takes the minerally flavor out of our tap water, but we only use it from drinking, not cooking water.

I agree the bottled water tripe is nonsense, and is surely damaging the eco systems of the world, and especially the ocean where it collects in spots to be eaten by birds and kills them.
