A professional who investigates causes and devises means to combat or eliminate electrolysis of water, gas, and oil mains and pipelines resulting from stray electric currents flowing in earth. Responsibilities include:

• Determines existence and locates sources of stray electric currents creating electrolytic conditions, using voltmeters, ammeters, and other electrical testing apparatus.
• Recommends preventive and corrective measures for protection of pipe and underground structures, such as use of insulating and corrosion resisting materials.
• Confers with power company personnel and power consumers and suggests methods to eliminate sources of power leakage.
• Studies destructive properties of soil, corrosive actions, and other problems of deterioration, and suggests methods of preventing or mitigating trouble.
• Writes reports of studies and investigations conducted.
• May design and direct installation of cathodic protection stations to minimize and control electrolysis.
• May design and construct apparatus for use in testing materials or determining location of stray electric currents.
