Does water conduct electricity?

[Ernie]

I'm just wanting to try and start an explanation of L rod movement.
Most L rod uses claim that they can find water. Yes/No?
So assuming Yes then does water conduct electricity? Yes/No?
From chemistry i've learnt that pure water (H20) (rainwater) cannot conduct electricity and therefor will have no magnetic fields but will be acted upon by gravity and so will have a weight. Yes/No?
But pure H2O very rarely exists below the ground in nature? And so H2O will have other conductive elements held in it as a suspended solution? Yes/No?
So an underground stream carrying conductive minerals such as gold will act as a type of conductor that can have a potential difference along its course? Yes/No?.
If the underground stream has potential and current flow then it should also have a magnetic field. Yes/No.?
If a gold element with a potential (amount) of energy (ability to do work) and a weight caused by a gravity force, travels down a hill stream to the ocean does it still have the same potential energy and weight? Yes/No?.
If No where did the difference in energy go?
If it was transfered into a strong magnetic energy or strong gravity force / weight enrgy in the stream can I detect it?
happy prospecting
