Stray electrical currents present the possibility for a costly and dangerous hazard—one that could and should be prevented with proper products and maintenance, but the costly and potentially dangerous effects of stray electrical currents warrant the study of this specific phenomenon. Shock hazards, accelerated corrosion of metal water pipes, and water quality problems such as the presence of lead or copper are the three main problems created by stray electrical currents. This paper reviews some of the main causes and results of stray currents, as well as protection choices for water pipeline systems.
