Claim 3:
4. A method comprising:
contacting at least a portion of a reference electrode of a reference electrode assembly with a ground surface at a test site, wherein the reference electrode assembly comprises:
an extension device comprising a first end opposite a second end, wherein the first end is engageable with the reference electrode and a fluid reservoir is disposed between the first end and the second end;
an end cap having an external electrical connector positioned at the second end of the extension device;
a selectively actuatable spout fluidly coupled to the fluid reservoir; and
a conductive wire extending through the fluid reservoir to electrically couple the reference electrode with the external electrical connector;

actuating the selectively actuatable spout to direct an amount of fluid from the fluid reservoir to the ground surface at the test site;
electrically coupling the reference electrode to a first terminal of a voltmeter;
electrically coupling a first portion of a metal structure to a second terminal of the voltmeter;
filling the fluid reservoir with a first volume of fluid;
contacting at least a portion of the reference electrode of the reference electrode assembly with the ground surface at a plurality of test sites;
actuating the selectively actuatable spout to direct a sub-volume of the first volume of fluid from the fluid reservoir to the ground surface at each of the plurality of test sites; and
determining the polarization of the metal structure at each of the plurality of test sites.
