L37780-01 NG425418 Cyanide,total M335 4-Colon metric w/ RA Relative Percent Difference(RPD)was not used for data
distillation validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL)
WG425103 Fluoride SM450OF-C RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<1 Ox MDL)
WG425246 Nitrate/Nitrite as N M353 2-H2SO4 preserved RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL)
WG424796 Phosphorus,ortho dissolved M365 1-Automated Ascorbic Acid HE Analysis performed past holding time Method holding time
is less than or equal to 7 days and sample was received
with less than half of the holding time remaining(refer to
item C5 of ACZ's Terms&Conditions)
M365 1-Automated Ascorbic Acid M1 Matrix spike recovery was high,the recovery of the
associated control sample(LCS or LFB)was acceptable
WG424886 Residue,Non-Filterable(fSS)@105C SM2540D RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL)
WG425368 Sulfate D516-02/-07-Turbidimetric M3 The spike recovery value is unusable since the analyte
concentration in the sample is disproportionate to the spike
level The recovery of the associated control sample(LCS
or LFB)was acceptable
L37780-02 NG425418 Cyanide,total M335 4-Colorimetric w/ RA Relative Percent Difference(RPD)was not used for data
distillation validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL)

M365 1-Automated Ascorbic Acid M1 Matrix spike recovery was high,the recovery of the
associated control sample(LCS or LFB)was acceptable
WG424886 Residue,Non-Filterable(TSS)@105C SM2540D RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL)
L37780-03 NG425100 Chloride SM4500CI-E RA Relative Percent Difference(RPD)was not used for data
