Sample Point Description:
Somewhat arbitrary sample point location within the OPC that is used as one of the "raw untreated" AMD sources after various seeps are collected. Sample just upstream of the Pipe 1 & Pipe 2 discharges.
- Records with no value are not included in statistical calculations.
- Values lower than the minimum detection limit are assumed to be 0.
- Average pH is calculated using the arithmetic mean of pH values. Hydronium ion concentrations were not used.
