It is neither sound nor proven, in fact it's wrong.

Water itself contains 1*10-7 mol/Liter positivly charged H+ and the
same amount of negativly charged HO- (ph 7) leading to a conductivity
of aprocimatly 0,055 ÁSiemens/cm (18,2 MOhm )for pure Water at 25 ░C
(compared with rainwater 35 - 100 ÁSiemens/cm dependent on Air
Polution, River (Rhein Germany ) 300 - 745 ÁSiemens/cm ,Sea 42

  The high conductivity of salty water are the Salt-ions but water has
in any case an amount of ions
