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