Notes:
B = Estimated value, less than the practical quantitation limit for that analyte, but greater than the method detection limit
U = Result less than method detection limit for that analyte
H = Analysis exceeded method hold time pH is a field test with an immediate hold time
Reanalysis preformed for analyte, reanalysis result reported.
Values in Bold exceeded benchmark levels
