Sample Point Description:

AMD deep mine discharge from the Gutten Drift is collected in a forebay.  Sample location is where the forebay is channeled into the VFP.  

  1. Records with no value are not included in statistical calculations.
  2. Values lower than the minimum detection limit are assumed to be 0.
  3. Average pH is calculated using the arithmetic mean of pH values. Hydronium ion concentrations were not used.
