Researchers team up to tackle state’s acid mine drainage problem
"As Penn State researchers stood on the banks of Scalp Level Run, an acid mine drainage (AMD)-polluted stream in Cambria County, a scientific question formed: How is nature removing toxic metals from the drainage at a rate faster than any other tested waters in the state, under pH conditions deemed too low to do so? For decades, cleanup efforts have involved raising the pH of AMD before using chemical oxidation to remove iron and other metals. And yet, at Scalp Level Run, the pollutants were being removed at a pH of around 3, and importantly, before entering the stream."
