If you can find an electrochemical pair that can make 35 volts with a

True but it would be interesting to know how the extremely low current
was measured as well before saying that the meter was displaying the
truth. Many digital meters display all sorts of rubbish under adverse
conditions.

in this case its displaying correct, as the source is low impedance.

It would be interesting to put a frequency counter or a 'scope in place

to see if it was indeed 50 Hertz mains ac. It could even be picking up
stray rf.

It probably is, but that will contribute only microvolts. Unless
someone's hidden 3 car batteries under there and put them in the earth
lead, its mains. And whats worse there are 2 dangerous faults. First
mains is flowing through the water due to bad insulaiton or wrong
wiring, and 2nd the thing isnt earthed. Whoever wired it up should kill
themselves by using it.
