I think you need more data to determine LD50. This woman appears to be a sport. The MSDS for water gives rat LD50=0.052gal/lb. So, for a 130 person, that's 6.8 gals.

I remember in medical school we studied this. A nephrologist told us that this kind of death happens at Oktoberfest in Germany. People not dying from drinking too much beer, but because they get too much water volume in their systems.

That shows "For Water: LD50 Oral Rat: >90 ml/Kg."

So for a 130lb rat, I think that would be about 1.401969192 gallons.
