While the majority of ,wastewater, streams generated from AMD are characterized by low pH (2-4) and high levels of dissolved ,iron, (1,000-10,000 ppm), there are some AMD streams that 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.
