@pyro, I keep thinking rather than even getting rid of waste, it’s just something they can claim costs for and pass onto the customers, even if the costs of doing it are less than they’re charging. Whose ever really going to know the real cost, after all, without doing a thorough audit of the billing system for various water companies and municipal water suppliers?
As to the claim, yes, fluoride causes a whole shit ton of problems, when you consume far more than is in our water supply. In fact, enough water is supplied to your home to cause problems if you consume enough of it in a short period of time. (Not too short though, or else you vomit before being poisoned.) Yes, water is toxic!
Of notable issues, one mechanism your body uses to deal with excess water free in the body is to simply absorb it into the cells. If a cell absorbs too much, it can actually explode. A bunch of cells doing this means a great deal of tissue damage, as well as now excess water free in the body once again, in need of absorption. It can actually create all the effects of drowning, except no water in the lungs, which has caused confusion at least once, until the medical examiner found out the woman had done a water drinking contest earlier that day for a radio station. (Drink as much water as she can without urination to win something or other, I know if you look up water toxicity on Wikipedia it’s covered there.)
So why then isn’t supplying water treated as a conspiracy theory?
Oops, I forgot about dihydrogen monoxide scares.
