A OZ Laboratories, Inc. 111 • • • O <br /> MI <br /> 2773 Downhill Drive Steamboat Springs, CO 80487 (800)334-5493 MIL - ! 4 <br /> ICItasca Denver, Inc. ACZ Project ID: L43424 <br /> .. <br /> WG445354 Silicon(MWMT) M6010B ICP B1 Target analyte detected in prep/method blank at or above <br /> the method reporting limit.See Case Narrative. <br /> M6010B ICP M2 Matrix spike recovery was low,the recovery of the <br /> associated control sample(LCS or LFB)was acceptable. <br /> M6010B ICP RD For a solid matrix,the duplicate RPD(spike or matrix) <br /> exceeded the control limit,which is attributable to the non- <br /> homogeneity of the sample. <br /> M6010B ICP ZH Serial Dilution exceeded the acceptance criteria. Matrix <br /> interference[physical or chemical]is suspected. <br /> WG444963 Silicon,recoverable(3050) M6010B ICP M2 Matrix spike recovery was low,the recovery of the <br /> associated control sample(LCS or LFB)was acceptable. <br /> M6010B ICP ZH Serial Dilution exceeded the acceptance criteria. Matrix <br /> interference[physical or chemical]is suspected. <br /> M6010B ICP ZQ Analyte was not evaluated in the laboratory control <br /> standard. Either the analyte is not included in the scope of <br /> the analytical method or a commercial standard containing <br /> the analyte is not available. <br /> M6010B ICP ZS Digestion procedures have the potential to trigger silica <br /> polymerization and precipitation,leading to low biased <br /> results. Silica chemistry is complex and polymerization <br /> kinetics are unpredictable. Dissolved and/or acid soluble <br /> silica analyses may provide more accurate measurements. <br /> WG445550 Silver(MWMT) M6020 ICP-MS RA Relative Percent Difference(RPD)was not used for data <br /> validation because the concentration of the duplicated <br /> sample is too low for accurate evaluation(<1Ox MDL). <br /> WG445354 Sodium(MWMT) M6010B ICP 131 Target analyte detected in prep/method blank at or above <br /> the method reporting limit.See Case Narrative. <br /> M6010B ICP RD For a solid matrix,the duplicate RPD(spike or matrix) <br /> exceeded the control limit,which is attributable to the non- <br /> homogeneity of the sample. <br /> WG445449 Sulfate(MWMT) D516-07-Turbidimetric HD Analysis is outside the intended scope of the method, <br /> which does not provide hold time information for soil <br /> extracts. No hold time is observed for collection to <br /> extraction. The referenced method hold time is observed <br /> for extraction-to-analysis. <br /> D516-07-Turbidimetric M3 The spike recovery value is unusable since the analyte <br /> concentration in the sample is disproportionate to the spike <br /> level.The recovery of the associated control sample(LCS <br /> or LFB)was acceptable. <br /> WG445550 Thallium(MWMT) M6020 ICP-MS RA Relative Percent Difference(RPD)was not used for data <br /> validation because the concentration of the duplicated <br /> sample is too low for accurate evaluation(<10x MDL). <br /> WG445499 Total Alkalinity SM2320B-Titration RA Relative Percent Difference(RPD)was not used for data <br /> validation because the concentration of the duplicated <br /> sample is too low for accurate evaluation(<10x MDL). <br /> WG445550 Uranium(MWMT) M6020 ICP-MS RA Relative Percent Difference(RPD)was not used for data <br /> validation because the concentration of the duplicated <br /> sample is too low for accurate evaluation(<1 Ox MDL). <br /> WG445354 Vanadium(MWMT) M6010B ICP RA Relative Percent Difference(RPD)was not used for data <br /> validation because the concentration of the duplicated <br /> sample is too low for accurate evaluation(<1 Ox MDL). <br /> WG444963 Zinc,total(3050) M6010B ICP ZH Serial Dilution exceeded the acceptance criteria. Matrix <br /> interference[physical or chemical]is suspected. <br /> REPAD.15.06.05.01 <br /> L43424-1805031420 Page 26 of 47 <br />
