<br /> Votes:
<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 than the practical quantitation limit
<br /> i=Analysis exceeded method hold time.pH is a field test with an immediate hold time.
<br /> VA=Analyte not analyzed
<br /> Jalues in Bold exceeded benchmark levels
