I was curious if it is possible to change the pH of water in the presence of an electric field. Specifically if a submerged well pump with an AC motor is improperly wired and there there is a circuit to the iron well casing then is it possible that the pH could be lowered? I have recently replaced a pump. The original pump had exposed wiring and the water was acidic. This caused corrosion of the copper pipes and associated blue-green staining. Having recently replaced the pump and properly wired it, the staining appears to be disappearing. This observation is the motivation for the question.
