An example test station assembly of a cathodic protection monitoring assembly includes a face plate including a plurality of openings. In addition, the test station assembly includes a plurality of test posts to pass through the plurality of openings. Further, the test station assembly includes a plurality of electrically non-conductive identification indicators to connect to the plurality of test posts on the face plate. Each of the plurality of identification indicators including one or more identifying characteristics to identify a corresponding voltage source of a plurality of underground voltage sources associated with an at least partially buried structure, a cathodic protection system for the buried structure, or the cathodic protection monitoring assembly. Still further, the test station assembly includes a plurality of electrical conductors to electrically connect the plurality of test posts to the plurality of underground voltage sources.
