METHODACZ ID WORKNUM PARAMETER QUAL DESCRIPTION
L68141-01 NG527063 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(<10x MDL).
WG527407 Beryllium(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).
WG527173 Bicarbonate as CaCO3 SM2320B-Titration Q6 Sample was received above recommended temperature.
WG527063 Boron(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).
WG526898 Bromide(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
referenced method hold time is observed for extraction-to-
analysis.
M300.0-Ion Chromatography M2 Matrix spike recovery was low,the recovery of the
associated control sample(LCS or LFB)was acceptable.
M300.0-Ion Chromatography 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 Cadmium(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).
WG527704 Carbon,total organic(TOC)(1312-DI) SM5310B 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.
SM5310B Q6 Sample was received above recommended temperature.
SM5310B 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).
WG527173 Carbonate as CaCO3 SM2320B-Titration Q6 Sample was received above recommended temperature.
WG526898 Chloride(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
referenced method hold time is observed for extraction-to-
analysis.
M300.0-Ion Chromatography 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).
WG527407 Chromium(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).
Cobalt(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).
WG527173 Conductivity @25C(1312-DI) SM2510B Q6 Sample was received above recommended temperature.
WG527407 Copper(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).
WG527502 Fluoride(1312 DI) 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(<1 Ox MDL).
WG527173 Hydroxide as CaCO3 SM2320B-Titration Q6 Sample was received above recommended temperature.
WG527063 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).
Lithium(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).
Magnesium(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).
WG527013 Mercury(1312) M7470A CVAA Q6 Sample was received above recommended temperature.
