Table 2: Comparison of November 2011 Concentrations to Benchmarks Levels
103 -81640
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
IN Constituent concentrations are above benchmark levels.
