Notes:
B=Estimated value,less than the practical quantitation limit for that analyte,but greater than the method detection limit
I 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
^=Second and third quarter 2015 reports presented calculated total dissolved solids results
Per Section 41.5(C)(6)the of Regulation 41,the"Interim Narrative Standard",is the minimum of Table 1-Table 4 of The Basic Standards for Groundwater(BSGW)
*TDS standard is 1.25*Background,where background is the average of the 1999-2000 sampling
I Values in bold indicate a value greater than the BSGW
**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(Tritium and Strontium)with known energy levels. Specific nuclides were not part of the approved constituent list.
