Pure water is virtually an insulator. I don't know why the amorphous "they"
say "don't stand in it."



Because the water that you stand in isn't pure, and dirty water
is a fairly good conductor, and wet feet and wet concrete are good
conductors.


And very little current is required for electrocution, IIRC about 100mA.
It is not too hard to get that thorugh relatively high resistance water.
Even easier to get enough current for a good shock. GFCIs trip at 5mA.

Earthing a service could involve thousands of amps.
