<br /> U=Analyte not detected,reported less than the practical quantitation limit
<br /> H=Analysis exceeded method hold time.pH is a field test with an immediate hold time.

<br /> "The regulatory standard for Gross Beta is provided in units of exposure,millirems per year(mrems/yr),which would require the measurement of specific nuclides(Tribum and Strontium)with known energy levels. Specific nuclides were not part of the approved constituent list.
