Sample Point Description:
Laurel Run at Rhine Road near Planet Earth.
- 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.
