I helped design ,construct, and now manage a class 4 100ML water plant in Southern Ontario.It is equipped with advanced taste and odour ozonation systems.
If you have a questions feel free to pm me.
99 out of 100 times bottled water is not needed in a house, house have to be in excess of 50 years old to have lead problems, if they have any.
A Brita in the filter will remove any combined chlorine taste and odours the water may pick up in its pipe travels.
