METHODACZ ID WORKNUM PARAMETER QUAL DESCRIPTION
L43419-01 WG445354 Aluminum(MWMT) M6010B ICP 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).
WG444963 Aluminum,total(3050) M6010B 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.
WG445550 Antimony(MWMT) M6020 ICP-MS 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).
WG444996 Antimony,total(3050) M6020 ICP-MS M2 Matrix spike recovery was low,the recovery of the
associated control sample(LCS or LFB)was acceptable.
WG445550 Arsenic(MWMT) M6020 ICP-MS 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).
WG445354 Barium(MWMT) M6010B ICP 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).
WG444963 Barium,total(3050) M6010B ICP ZH Serial Dilution exceeded the acceptance criteria. Matrix
interference[physical or chemical]is suspected.
WG445550 Beryllium(MWMT) M6020 ICP-MS 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).
WG445354 Boron(MWMT) M6010B ICP B1 Target analyte detected in prep/method blank at or above
the method reporting limit.See Case Narrative.
M6010B ICP ZG The ICP or ICP-MS Serial Dilution was not used for data
validation because the sample concentration was less than
50 times the MDL.
Calcium(MWMT) M6010B ICP B1 Target analyte detected in prep/method blank at or above
the method reporting limit.See Case Narrative.
M6010B ICP RD For a solid matrix,the duplicate RPD(spike or matrix)
exceeded the control limit,which is attributable to the non-
homogeneity of the sample.
WG445498 Chloride(MWMT) SM4500CI-E HD Analysis is outside the intended scope of the method,
which does not provide hold time information for soil
extracts. No hold time is observed for collection to
extraction. The referenced method hold time is observed
for extraction-to-analysis.
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(<1 Ox MDL).
WG445354 Chromium(MWMT) M6010B ICP 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).
WG445552 Cyanide,WAD(MWMT) SM4500-CN I,E-Colorimetric w/ M1 Matrix spike recovery was high,the recovery of the
distillation associated control sample(LCS or LFB)was acceptable.
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(<10x MDL).
WG445704 Fluoride(MWMT) SM450OF-C 61 Target analyte detected in prep/method blank at or above
the method reporting limit.See Case Narrative.
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(<10x MDL).
WG445354 Iron(MWMT) M6010B ICP 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).
WG444963 Iron,total(3050) M6010B 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.
M6010B ICP ZH Serial Dilution exceeded the acceptance criteria. Matrix
interference[physical or chemical]is suspected.
WG445550 Lead(MWMT) M6020 ICP-MS 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).
WG445354 Lithium(MWMT) M6010B ICP RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
