here was a local story with a video.

Dr. John Sibert, an associate professor of Chemistry at the University of Texas at Dallas, says the color change can be explained by simple science.

"Electrolysis, which is used in the marketing of that product, is a very basic chemical process that involves electrical energy being used to do some chemical change," Dr. Sibert said.

He says the orange color in the water is a result of iron in its oxidized form. That's rust.
