Fisher Creek, a stream affected by acid mine drainage in the Beartooth Mountains of Montana, was studied to determine the extent to which copper and zinc would be removed from stream water when pH was increased by a pulse of sodium hydroxide. As stream pH increased, copper and zinc were rapidly and completely removed from stream water by adsorption or coprecipitation with freshly precipitated hydrous ferric oxide. In practice, the best way of increasing the pH of streams impacted by acid mine drainage would be to increase the alkalinity of tributaries by lining their channels with limestone rock.
