you can consume the water as long as you put in enough electrolytes. vitalyte, gatorade etc.,to much water can flush your system of good nutrients.
Years ago the same thing happened to a radio show contestant. The game was to see who could drink the most water in the shortest amount of time. The lady that played died of water poisioning. Proof the too much of a good thing can kill you. RIP Concho Man! Let this event serve as a warning to the other canoe paddlers. Be carefull of how much water you drink in "X" amount of time.
That's a tough one. A high school football player died the same way during, or right after, practice a couple years back. My best to his family and friends.
Tragic events. Who ever would have thought that drinking water could kill you. My condolences to the family and friends.
