Notes
B = Estimated value, less than the practical quantiation limit for that analyte, but greater than the method detection limit
H = Analysis exceeded method hold time. pH is a field test with an immediate hold time
U = Analyte not detected above the method detection limit, result reported as less than ( <) the practical quantitation limit
