t Notes:
B=Estimated value,less than the practical quantitation limit for that analyte,but greater than the method detection limit
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(when available)
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(mremstyr),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.
