METHODACZ ID WORKNUM PARAMETER QUAL DESCRIPTION
L50185-01 NG467342 Antimony,dissolved M200.8 ICP-MS Q5 Sample received with inadequate chemical preservation.
Additional preservation performed by the laboratory.
Arsenic,dissolved M200 8 ICP-MS Q5 Sample received with inadequate chemical preservation.
Additional preservation performed by the laboratory
WG467461 Cyanide,WAD SM4500-CN I,E-Colonmetric w/ M2 Matrix spike recovery was low,the recovery of the
distillation associated control sample(LCS or LFB)was acceptable.
SM4500-CN I,E-Colormetric 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).
WG467565 Iron,total M200 7 ICP 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
WG467342 Lead,dissolved M200 8 ICP-MS Q5 Sample received with inadequate chemical preservation
Additional preservation performed by the laboratory.
WG467381 Mercury,dissolved M245 1 CVAA Q5 Sample received with inadequate chemical preservation
Additional preservation performed by the laboratory.
WG467582 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).
WG467447 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).
WG467177 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).
WG467342 Silver,dissolved M200.8 ICP-MS Q5 Sample received with inadequate chemical preservation.
Additional preservation performed by the laboratory.
Thallium,dissolved M200.8 ICP-MS Q5 Sample received with inadequate chemical preservation.
Additional preservation performed by the laboratory.
WG467403 Uranium,dissolved M200.8 ICP-MS Q5 Sample received with inadequate chemical preservation.
Additional preservation performed by the laboratory.
L60186-02 NG467177 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).
L50185-03 ✓VG467177 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).
