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(mremslyr),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.
