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