Iron in drinking water may pose more health risks than federal water regulators currently acknowledge.
Marc Edwards, an environmental engineering professor at Virginia Tech, says that iron may have played a critical role in the Flint lead-contamination crisis, according to WWL-TV.
Edwards helped uncover the severity of the lead crisis in Flint. He explained to WWL-TV how iron can have a negative impact on the water system.
“[Iron] increases the leaching of lead into the water,” Edwards said.
“While the iron itself won't likely make people sick, Edwards says high iron in the water can remove disinfectants like chlorine, allowing harmful bacteria to grow. Bacteria like legionella, which causes Legionnaire’s Disease. That's what Edwards said he believes may have happened in Flint,” the report said.
