INCHCAPE TESTING SERVICES, SAN JOSE LABORATORIES REPORT DESCRIPTION - INORGANICS Analytical Data Report(ADR) ' The ADR contains tabulated results for inorganic analytes All field samples, QC samples and blanks were prepared and analyzed according to procedures in the following references — "Test Methods for Evaluating Solid Waste,"SW-846,EPA,3rd Edition,1994 ' "Methods for Chemical Analysts of Water and Wastes,"EPA,3rd Edition,I983 CCR Title 22,Section 66261,Appendix 11,California Waste Extraction Test CCR Title 22 Section 66261,Appendix M,Organic Lead — "Standard Methods for the Examination of Water and Wastewater,"APHA,AW WA,WEF,' 18th Edition, 1992_ USEPA Contract Laboratory Program Statement of Work for Inorganic Analyses,ILM02 1,IL th E ti II 199 0, 1991-1995 Matrix Spike Report(MSR) The MSR summarizes the percent recovery and relative percent difference information for matrix spikes and matrix spike duplicates This ' Information is a statement of both accuracy and precision MSRs may not be provided with all analytical reports Laboratory Control Sample Report(LCSR) ' The LCSR summarizes percent recovery information for laboratory control spikes on reagent water or soil This information is a statement of performance for the method,i e,the samples are properly prepared and analyzed according to the applicable methods Method Blank Report(MBR) The MBR summarizes quality control information for rex the method blank should be below the method r eportmg lgents used in preparing samples The absolute value of each analyte measured in imit(PQL)for that analyte Post Digestion Spike Report(PDSR) The PDSR summarizes percent recovery information for post digestion spikes A post digestion spike is performed for a particular analyte if the matrix spike recovery is ou#sde of estabhshed controI limits Any percent recovery for a post digestion spike outside of established limits for an analyte indicates probable matrix effectsand interferences for that analyte Qualifiers(Q) ITS-SI uses several data qualifiers in inorganic reports These qualifiers give additional information on the analytes reported The following is a list of qualifiers and their meanings I- Sample was analyzed at the stated dilution due to interferences ' U- Analyte concentration was below the applicable reporting limit For matrix and post digestion spike reports a value of "0 0"is entered for calculation of the percent recovery B- Sample concentration was below the reporting limit but above the instrument detection limit Result is entered for calculation of the percent recovery only ' H- Spike percent recovery is not calculated due to possible interferences from relatively high concentration level of the analyte in the uuspiked sample Comment Codes ' In addition to qualifiers,the following codes are used In the comment section of all reports to give additional information about sample preparation methods p A- Sample was prepared for silver based on the silver digestion method developed by the Southern California Laboratory Department of Health Services "Acrd Ingestion for Sediments Sludges, Sorts and Solid Wastes A Proposed Alternative to EPA SW846 Method.3050"Environmental Science and Technology 1989,23,898-900 C- Spikes were prepared after extraction by the California Waste Extraction Test(CWET)method D- Reported results are dissolved,not total metals Spikes were prepared after filtration Reporting Conventions Analytical values reported are gross values i e,not corrected for method blank contamination Solid matrices are reported on a wet weight basis,unless noted f tirc[mclmehlslcove[ahllarddoc J � 05 ?
