Not to play devil's advocate here, but I dont believe in the while RO/DI water thing for health reasons. Do I drink RO/DI water? You betcha! Do I drink my tap water? Of course! The RO/DI water tastes clean and for that reason I buy it in bulk. However, I still believe in my tap water. I used your resources and found that my supplier was only found with 9 pollutants in the water all well below the average levels and 0 citations or illegal levels in the past 8 years.
One thing you have to think about is that our tap water is treated with beneficial addatives as well. While you can buy bottled water with flouride added, why pay for it? I dunno, my brother (who is a discriminative water drinker) will tell you that my tap water tastes like bottled water.
If the city I lived in didnt have as high of a water standard or if I lived in an old house with copper pipes, I probably would refrain from drinking the tap water, but otherwise....I'm all good with it and so are my teeth!
