10/11/2004· Equation 4 shows that by introducing hydrogen ions, acid mine drainage affects the acidity of a stream. Acidity is commonly measured by pH values, which are easy to collect and compare. pH, however, is not always a good indior of acid mine drainage because it only indies the concentration of hydrogen ions.
