Notes:
B = Estimated value, less than the practical quantitation limit for that analyte, but greater than the method detection limi
U = Analyte not detected, reported less than the practical quantitation limi
H = Analysis exceeded method hold time. pH is a field test with an immediate hold time
NA = Analyte not analyzed
