METHODACZ ID WORKNUM PARAMETER QUAL DESCRIPTION
L71577.01 NG537399 Cyanide,WAD SM4500-CN I,E-Colorimetric wl 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).
WG538012 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(<lox MDL)
WG537423 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(<lox MDL).
WG537195 Residue,Non-Fifterable(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(<lox MDL).
SM2540D Z3 Sample volume yielded a residue less than 2 5 mg
WG538118 Sulfate D516-02/-07/-11- M2 Matrix spike recovery was low,the recovery of the
TURBIDIMETRIC associated control sample(I-CS or LFB)was acceptable
WG537643 Total Hot Plate Digestion M200 2 ICP OA Sample container with preservation type specified by the
method was not available for analysis. Altemate sample
container was used.
WG537403 Total Recoverable Digestion M200 2 ICP-MS DJ Sample dilution required due to insufficient sample.
L71577-02 NG537399 Cyanide,WAD SM4500-CN I,E-Colonmetric 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(<lox MDL)
WG538012 Nftrate/Ndrde 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(<lox MDL).
WG537423 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)
WG537195 Residue,Non-Fifterable(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(<lox MDL).
SM2540D Z3 Sample volume yielded a residue less than 2 5 mg
WG537570 Silver,dissolved M200 8 ICP-MS RF Relative Percent Difference(RPD)for Ag in spiked samples
exceeded limit In the absence of HCI,precipitation of Ag
may occur at different rates
WG538118 Sulfate D516-02/-07/-11- M2 Matrix spike recovery was low,the recovery of the
TURBIDIMETRIC associated control sample(I-CS or LFB)was acceptable.
