L69171-01 JNG532746 Acid Generation Potential(calc) M600/2-78-054 1.3 N1 See Case Narrative.
Acid Neutralization Potential(calc) M60012-78-054 1.3 N1 See Case Narrative.
Acid-Base Potential(calc) M600/2-78-054 1.3 N1 See Case Narrative.
W G530787 Aluminum(1312) M601 OD 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).
WG530915 Antimony(1312) M6020B ICP-MS 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.
M6020B 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.
Arsenic(1312) M6020B ICP-MS ZH Serial Dilution exceeded the acceptance criteria. Matrix
interference[physical or chemical]is suspected.
Barium(1312) M6020B ICP-MS ZH Serial Dilution exceeded the acceptance criteria. Matrix
interference[physical or chemical]is suspected.
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).
WG530612 Bicarbonate as CaCO3 SM2320B-Titration Q6 Sample was received above recommended temperature.
W G530712 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).
W G531493 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(<1Ox MDL).
WG530915 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(<1 Ox MDL).
WG531038 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(<1 Ox MDL).
WG530612 Carbonate as CaCC3 SM2320B-Titration Q6 Sample was received above recommended temperature.
WG531493 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(<,10x MDL).
WG530915 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(<1 Ox 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(<1 Ox MDL).
WG530612 Conductivity @25C(1312-DI) SM2510B Q6 Sample was received above recommended temperature.
WG530915 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).
