Sample Point Description: Espy Run above the treatment system and above 2 seeps that come out near an ATV stream crossing. There still may be other small seeps intermixed with groundwater from the swampy(headwater) area upstream. Orange flocculate seen sometimes, clear other times.
- 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.

Sample Point Description: AMD; Sampled at the pipe that takes water from the intake to the new pond A & B (Same as B1 and B2 on schematic). The pipe discharges into a channel that feeds both ponds. This channel is a half pipe that needs continual maintenance to remove the AMD sludge buildup and keep the water running to both ponds. AKA ESPYIN and Espy Run TS Influent New Pipe

Sample Point Description: Espy Run downstream of the treatment system and the USGS gauging station.
- 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.
