A random fluctuation in the tunneling current of a metal-water-metal junction between two discrete levels was observed. Fluctuations were studied as a function of the tunnel gap width and applied vias voltage in pure water, organic solvent, and in the presence different ions of various concentrations. Results were explained by the existence of a low-lying local state in the water layer between the metal electrodes.
