METHODACZ ID WORKNUM PARAMETER DESCRIPTION
L60767-01 ✓VG469715 Chloride SM4500CI-E M2 Matrix spike recovery was low,the recovery of the
associated control sample(LCS or LFB)was acceptable.
WG469091 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).
WG470185 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(<1 Ox MDL).
WG469437 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(<10x MDL).
WG469083 Residue,Filterable(TDS)@180C SM2540C B7 Target analyte detected in prep/method blank at or above
acceptance limit. Sample value is>1 OX the concentration
in the method blank.
WG468861 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(<1Ox MDL).
SM2540D Z3 Sample volume yielded a residue less than 2.5 mg
WG469787 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.
D516-021-07-Turbidimetric 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).
