complete with chlorine and flouride added? also, from a microbial activity and/or organic contaminants point of view, tap water probably has orders of magnitude less than most streams.

>Prescription / OTC drugs can mess with us fairly seriously if not used carefully and in recommended quantities, so this is actually a good analogy.

What's the equivalent statement for "the quantities of sugar that we on average do consume", but for drugs? I'd say that a big chunk of the population consumes infinitely more antidepressants and cholesterol-lowering drugs than we were "designed to consume".

Connecting these two topics together, there are localities that have naturally occurring lithium in their water supply. Depression and suicide rates in these areas are lower than average.
