Just as many toxins don't have a linear response, they also don't have a dose independent response. In some cases, a little bit of a toxin might be far less harmful if not even beneficial, since the response mechanism is not overwhelmed. Think of oxygen, for instance. Seriously toxic, but try living without it right now.
But also think of the huge number of other toxins you're immersed and bathed in everyday. You don't necessarily experience much harm from them. Still, no reason to intentionally add a known toxin and extremely active substance into the water supply. (Even in the case of chlorine, it's great for killing pathogens, but it's probably better not to be drinking and breathing it because one has it in the water supply one drinks and bathes with.)
