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