Corrosion control occurs when naturally forming minerals deposit on pipe walls, thereby protecting the iron pipe surfaces from exposure to oxidants in the water. Changes in water quality sometimes dissolve these mineral coatings, exposing the pipe to corrosion.
Why is the Flint River toxic?
After decades of industrial dumping by GM and its suppliers, the Flint River became polluted. High levels of chlorides in the water corroded Flint’s lead pipes, leading to unsafe levels of the metal in drinking water; children, too, tested with elevated blood lead levels.
