Technically, pure water, or an amount of nothing but H2O molecules will not in any way conduct electric current. Free or valance electrons are what flow in a current. Well, the balanced molecule of water has no free electrons, they're all used in forming the molecule. A tub or glass or container of water conducts electric current since normally the water is not pure. It has minerals, dirt, or other particles of other atoms or molecules in it. If you were to take two perfectly sterilized leads and place them into a solution of absolutely pure, distilled water, there would be no conductivity until contaminants from atmosphere started to get into the water giving something for the current to flow across from one lead to the other.
either way,even unpure water is a bad conducter
