METHODACZ ID WORKNUM PARAMETER QUAL DESCRIPTION
M7470A 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).
WG527407 Nickel(1312) M6020B 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).
WG526968 Nitrate/Nitrite as N(1312-DI) M353.2-Automated Cadmium H1 Sample prep or analysis performed past holding time. See
Reduction case narrative.
M353.2-Automated Cadmium Q6 Sample was received above recommended temperature.

M353.2-Automated Cadmium Q6 Sample was received above recommended temperature.
Reduction
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(<10x MDL).
WG528027 Nitrogen,ammonia(1312-DI) M350.1 Auto Salicylate w/gas HD Analysis is outside the intended scope of the method,which
diffusion 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.
M350.1 Auto Salicylate w/gas Q6 Sample was received above recommended temperature.
diffusion
M350.1 Auto Salicylate w/gas RA Relative Percent Difference(RPD)was not used for data
diffusion validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
WG526969 Phosphorus,ortho dissolved(1312-DI) M365.1-Automated Ascorbic 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.
M365.1-Automated Ascorbic M2 Matrix spike recovery was low,the recovery of the
associated control sample(LCS or LFB)was acceptable.
M365.1-Automated Ascorbic 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).
WG526965 Phosphorus,Total(1312-DI) M365.1-Auto Ascorbic Acid HD Analysis is outside the intended scope of the method,which
(digest) 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.
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).
WG527063 Potassium(1312) M6010D 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).
WG527181 Residue,Filterable(TDS)@180C(1312) SM2540C 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).
WG527384 Residue,Non-Filter(TSS)@180C(1312-SM2540D RA Relative Percent Difference(RPD)was not used for data
DI) validation because the concentration of the duplicated
sample is too low for accurate evaluation(<1 Ox MDL).
SM2540D Z3 Sample volume yielded a residue less than 2.5 mg
WG527407 Selenium(1312) M6020B 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).
Silver(1312) M6020B 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).
WG527063 Sodium(1312) M6010D 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.
WG526898 Sulfate(1312-DI) M300.0-Ion Chromatography 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
