I’m assuming you’re employed? Not everyone will have a brita filter or the inclination to pay out their ass for bottled water.

EDIT: I don't mean to be a dick or even argue, I'm just pointing out that these problems do affect people, just maybe not most people through an effective combination of factors that reduces risk (where you live, whether you can afford a filter, etc). I certainly grew up on tap water and I am mildly disturbed people are ok with it causing massive mental health issues.

EDIT 2: Finally, I don't filter water I cook with; I imagine lead would still be a problem there. I probably should filter that water too in Oakland....

I always wonder if these "toxins in the tap water are tolerable" people ever eat at restaurants. Do they know where the water used to prepare food and make coffee and tea comes from?
