METHODACZ ID WORKNUM PARAMETER QUAL DESCRIPTION
L49574-01 NG465804 Aluminum(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)
WG465707 Aluminum,total(3050) M6010D 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
WG465763 Antimony(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)
WG465683 Antimony,total(3050) M6020B ICP-MS M2 Matrix spike recovery was low,the recovery of the
associated control sample(LCS or LFB)was acceptable
WG465763 Arsenic(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)
WG465804 Barium(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)
WG465707 Barium,total(3050) M6010D 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
WG465804 Beryllium(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)
WG465621 Bicarbonate as CaCO3 SM2320B-Titration Q6 Sample was received above recommended temperature
WG465804 Cadmium(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)
Calcium(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(<10x MDL)
WG465621 Carbonate as CaCO3 SM2320B-Titration Q6 Sample was received above recommended temperature
WG465689 Chloride(1312 DI) 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(<10x MDL)
WG465804 Chromium(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(<10x MDL)
Cobalt(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)
WG465621 Conductivity @25C(1312-DI) SM2510B Q6 Sample was received above recommended temperature
SM2510B 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)
WG465804 Copper(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)
WG465621 Hydroxide as CaCC3 SM2320B-Titration Q6 Sample was received above recommended temperature
WG465804 Iron(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)
WG465707 Iron,total(3050) M6010D 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
WG465763 Lead(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)
M6020B ICP-MS ZG The ICP or ICP-MS Serial Dilution was not used for data
validation because the sample concentration was less than
