While the majority of waste streams generated from acid mine drainage (AMD) are characterized by low pH (2-4) and high dissolved iron (1,000 – 10,000 ppm), there are some AMD streams which are not contaminated to these extremes. These streams may have relatively high pH levels (5-7) and dissolved iron levels as low as several hundred ppm.
