L73416-01 NG543878 Arsenic,total M200 8 ICP-MS VC CCV recovery was above the acceptance limits.Target
analyte was not detected in the sample[<MDL].
WG543476 Cyanide,WAD SM4500-CN I,E-Colodmetric 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).
W G544045 Nitrate/Nftnte 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(<1 Ox MDL).
W G544069 Phosphorus,total M365.1-Auto Ascorbic Acid RA Relative Percent Difference(RPD)was not used for data
(digest) validation because the concentration of the duplicated
sample is too low for accurate evaluation(<1 Ox MDL).
WG543098 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(<1 Ox MDL)
SM2540D Z3 Sample volume yielded a residue less than 2.5 mg
WG543616 Sulfate D516-02/-07/-11- M3 The spike recovery value is unusable since the analyte
TURBIDIMETRIC concentration in the sample is disproportionate to the spike
level.The recovery of the associated control sample(LCS
or LFB)was acceptable.
L73416-02 NG543476 Cyanide,WAD SM4500-CN I,E-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(<1 Ox MDL)
