Anything in excess can be bad, even water. There have been cases of people dying due to drinking too much water. The most common cases are drinking too much water during drinking competitions and during intense exercise.
The only realistic way of dying from drinking too much water is like from back when it was on the news regarding those college kids that were drinking excessive amounts all at one time and they were actually drowning their organs from doing that, not from drinking too much water during intense exercise which would be almost impossible because you would start to lag during your workout...it's obviously important to drink water while exercising, it's obviously stupid to over-drink water as a frat prank and drown your organs and die.
I was making a point that too much of anything isn't good. Of course, some things are easier to have too much of.
Anyway, it is possible to die from drinking too much water while exercising. In fact, medical personnel at marathon events are trained to immediately suspect water intoxication when runners collapse or show signs of confusion. Apparently, athletes sweat heavily, losing both water and electrolytes. Water intoxication and hyponatremia result when a dehydrated person drinks too much water without the accompanying electrolytes.
