Effect of Grounding and electrical properties ON WATER QUALITY

“…For many years, the water utility industry has had concerns about the effect of grounding currents on water quality. Early research on the subject included studies that focused primarily on grounding's effects on water quality in terms of taste and odor (American Research Committee on Grounding, 1944; Eliassen & Goldsmith, 1944; Eliassen, 1941; Warren, 1934). In these studies, alternating current and direct current (AC and DC) were conducted along lengths of electrically continuous metallic water service piping and measured the change in metal ion concentration over a period of time.…”

“…Previous studies on the effects of grounding on water quality and metal release have not investigated the effects of resistance or dielectric fittings on water quality. Without significant resistance in the metal pipe wall, electrical current continues to flow in the much more conductive pipe wall (OUC & CH2M HILL, 1994; Guererra, 1979; Eliassen, 1941). Current is not discharged on the inside or the outside of pipe, and it is not surprising that no effect on water quality was previously found when electrically continuous pipe sections were tested.…”
