METHODACZ ID WORKNUM PARAMETER QUAL DESCRIPTION
L34107-01 WG413372 Total Hot Plate Digestion M200 2 ICP-MS DJ Sample dilution required due to insufficient sample.
WG413374 Total Recoverable Digestion M200.2 ICP DJ Sample dilution required due to insufficient sample
WG413483 Chloride SM4500CI-E RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<IOx MDL)
WG413526 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(<1 Ox MDL).
WG413524 Cyanide,WAD SM4500-CN I,E-Colorimetnc 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).
WG413109 Dissolved Chromium,Hexavalent SM350OCr-B 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).
SM350OCr-B 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).
SM3500Cr-B ZU Analysis datettime preceeds filter datettime. A portion of
sample was filtered and analyzed prior to the creation of a
Filter workgroup
WG413315 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).
WG413700 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(<1 Ox MDL)
WG413114 Phosphorus,ortho dissolved M365 1-Automated Ascorbic Acid 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)
WG413239 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).
WG413502 Sulfate D516-02/-07-Turbidimetric M1 Matrix spike recovery was high,the recovery of the
associated control sample(LCS or LFB)was acceptable.
