PARAMETER METHOD QUAL DESCRIPTION
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
sample is too low for accurate evaluation(<1 Ox MDL).
WG444963 Lithium,total(3050) 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.
M6010B ICP ZQ Analyte was not evaluated in the laboratory control
standard. Either the analyte is not included in the scope of
the analytical method or a commercial standard containing
the analyte is not available.
Manganese,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.
WG445100 Mercury(MWMT) M7470 CVAA H3 Sample was received and analyzed past holding time.
M7470 CVAA 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).
WG444901 Mercury by Direct Combustion AA M7473 CVAAS H3 Sample was received and analyzed past holding time.
M7473 CVAAS 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.
WG445354 Molybdenum(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).
WG444963 Molybdenum,total(3050) M6010B ICP M2 Matrix spike recovery was low,the recovery of the
associated control sample(LCS or LFB)was acceptable.
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.
WG444619 NAG Sequential NAG-EGI 2002 N1 See Case Narrative.
WG444963 Nickel,total(3050) 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.
WG445105 Nitrate/Nitrite as N(MWMT) M353.2-Automated Cadmium HD Analysis is outside the intended scope of the method,
Reduction 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.
M353.2-Automated Cadmium RA Relative Percent Difference(RPD)was not used for data
Reduction validation because the concentration of the duplicated
sample is too low for accurate evaluation(<1 Ox MDL).
WG445834 Nitrogen,total Kjeldahl(MWMT) M351.2-Block Digestor 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.
M351.2-Block Digestor 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).
WG444619 pH After Oxidation Sequential NAG-EGI 2002 N1 See Case Narrative.
WG445354 Potassium(MWMT) 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.
WG445300 Residue,Filterable(TDS)@180C SM2540C B7 Target analyte detected in prep/method blank at or above
(MWMT) acceptance limit. Sample value is>10X the concentration
in the method blank.
SM2540C 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.
WG445173 Selenium,total(3050) M6020 ICP-MS 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.
