>distilled water seems like a better bet than drinking ground water

Those are not the only two options. There is a third option that exists, it's called purified water and it leaves the important minerals and salts in the water. Water can be purified without being distilled, and even your own source says distilled water will leach chemicals from the plastic container into the water. Distilled water is what you put into a car's radiator or a home humidifier, not into your body.

There are plenty of sources from actual medical journals and the WHO (not random Internet blogs) on the negative health impacts of distilled water here: https://en.wikipedia.org/wiki/Distilled_water#Health_effects
