Sample Point Description:

Sampled above Laurel Run Treatment System #2.  (Also identified as LR1.)

  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.
