Water in an old building, tested recently, showed high copper and iron content, and low ph levels. a water reading taken 20 years before showed low ph levels, but only minimal traces of copper and iron. if none of the new buildings on the same street showed signs of metallic contaminants, but all reported lower than normal ph readings, how might these readings be explained?
