METHODACZ ID WORKNUM PARAMETER QUAL DESCRIPTION
L18297-01 WG364392 Aluminum,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.
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.
Manganese,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.
Silica,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.
M200.7 ICP IRS RPD of matrix spikes for total or total recoverable silica is
outside acceptance limits. Acceptable precision for other
metals indicates silica RPD failure may be attributed to
digestion-triggered silica polymerization and precipitation.
M200.7 ICP ZS Digestion procedures have the potential to trigger silica
polymerization and precipitation,leading to low biased
results. Silica chemistry is complex and polymerization
kinetics are unpredictable. Dissolved and/or acid soluble
silica analyses may provide more accurate measurements.
WG364502 Chloride SM4500CI-E M1 Matrix spike recovery was high,the recovery of the
associated control sample(LCS or LFB)was acceptable.
WG364640 Cyanide,total M335.4-Colorimetric w/ RA Relative Percent Difference(RPD)was not used for data
distillation validation because the sample concentration is too low for
accurate evaluation(<1 Ox MDL).
WG364641 Cyanide,WAD SM4500-CN I-Colorimetric w/ RA Relative Percent Difference(RPD)was not used for data
distillation validation because the sample concentration is too low for
accurate evaluation(<1Ox MDL).
WG364272 Fluoride SM450OF-C RA Relative Percent Difference(RPD)was not used for data
validation because the sample concentration is too low for
accurate evaluation(<1 Ox MDL).
WG364143 Phosphorus,ortho dissolved M365.1-Automated Ascorbic QP The sample was filtered at the laboratory more than 15
Acid minutes after sample collection. For Orthophosphate,40
CFR Part 136.3 requires filtration within 15 minutes of
collection.
M365.1-Automated Ascorbic RA Relative Percent Difference(RPD)was not used for data
Acid validation because the sample concentration is too low for
accurate evaluation(<10x MDL).
M365.1-Automated Ascorbic ZU Analysis date/time preceeds filter date/time. A portion of
Acid sample was filtered and analyzed prior to the creation of a
Filter workgroup.
WG364338 Residue,Non-Filterable(TSS)@105C SM2540D RA Relative Percent Difference(RPD)was not used for data
validation because the sample concentration is too low for
accurate evaluation(<1 Ox MDL).
WG364620 Sulfate D516-02-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.
