METHOD,ACZ ID WORKNUM PARAMETER QUAL DESCRIPTION
L74959-01 VVG548075 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)
WG549132 Fluoride SM450OF-C MA Recovery for either the spike or spike duplicate was outside
of the acceptance limits;the RPD was within the
acceptance limits.
WG548826 Nitrate/Nitnte 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).
WG548459 Phosphorus,total W65 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)
WG548028 Residue,Filterable(TDS)@180C SW540C 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)
WG548085 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)
SM2540D Z3 Sample volume yielded a residue less than 2 5 mg
WG548221 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.
D516-02/-07/-11- RA Relative Percent Difference(RPD)was not used for data
TURBIDIMETRIC validation because the concentration of the duplicated
sample is too low for accurate evaluation(<1 Ox MDL)
WG549397 Total Hot Plate Digestion M200 2 ICP-MS DJ Sample dilution required due to insufficient sample.
