Promiscuous Electric Grounding on Water Service Pipes and Mains

Discussion

“…The method proposed by Fair was used as a means to permit comparison of odor and taste constituents on a direct quantitative or numerical basis. The results of the electrical research thus far available confirm and strengthen the hypothesis presented in a joint paper at the Chicago Convention in 1933 (2). Odors not detectable in the water from a series of laboratory test pipes reach a considerable intensity when the current is flowing and disappear when the current is cut off.…”

Report of a Research Project on the Effects of Electric Grounding on Water Pipes

“…Many engineers have advocated separate grounds for all electrical circuits, eliminating all possible connections to the water systems. Reasons' for this have been varied, but the most prevalent one has been the claim that internal corrosion of the water lines will result, with consequent effect on the quality of the water, as evidenced by tastes and odors (2).…”

Program for Research on the Effects of Electric Grounding on Water Pipes

“…The presence of metallic ions in the water may affect its quality and render it undesirable for human consumption. It is evidenced by such common phenomena as the staining of plumbing fixtures, the occurrence of red water and certain characteristic tastes and odors (7). The approach to this problem will be an experimental one.…”
