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
1 - Most restrictive standard set by the Water Quality Control Commission in tables 1 through 4 of Regulation 41
Constituent concentrations are above benchmark levels.
