Notes:
B = Estimated value, less than the practical quantitation limit for that analyte, but greater than the method detection limit
U = Analyte not detected, reported less then the practical quantation limit
H = Analysis exceeded method hold time. pH is a field test with an immediate hold time.
NA = Analyte not analyzed
* Reanalysis preformed for analyte, reanalysis result reported.
Values in Bold exceeded benchmark levels
