Treating Arsenic and Selenium in Mine-Influenced Waters

Acid rock runoff or acid mine drainage requires treatment because, untreated, it makes water uninhabitable for aquatic life. Contaminants such as arsenic and selenium can occur in both acid mine drainage and mine-influenced waters that have a neutral pH, depending on local conditions. In both cases, these two contaminants also require treatment.
