Refer to the ALS Quality Control Interpretive report (QCI) for applicable references and methodology summaries. Reference methods mayincorporate modifications to improve performance.Where a reported less than ( ) result is higher than the LOR, this may be due to primary sample extract/digestate dilution and/or insufficient sample for analysis.Where the LOR of a reported result differs from standard LOR, this may be due to high moisture content, insufficient sample (reduced weight employed) or matrix interference.Please refer to Quality Control Interpretive report (QCI) for information regarding Holding Time compliance.Key :CAS Number: Chemical Abstracts Services number is a unique identifier assigned to discrete substancesLOR: Limit of Reporting (detection limit).UnitDescription%percentmg/kgmilligrams per kilogrammg/Lmilligrams per litrepH unitspH units : less than. : greater than.Surrogate: An analyte that is similar in behavior to target analyte(s), but that does not occur naturally in environmental samples. For applicable tests, surrogates are added to samples prior to analysisas a check on recovery.Test results reported relate only to the samples as received by the laboratory.UNLESS OTHERWISE STATED on SRN or QCI Report, ALL SAMPLES WERE RECEIVED IN ACCEPTABLE CONDITION.Analytical results in reports identified as “ Preliminary Report” are considered authorized for use.

In the absence of regulatory hold times, ALS establishes recommendations based on guidelines published by organizations such as CCME, US EPA, APHA Standard Methods, ASTM, orEnvironment Canada (where available). Dates and holding times reported below represent the first dates of extraction or analysis. If subsequent tests or dilutions exceeded holding times, qualifiersare added (refer to COA).If samples are identified below as having been analyzed or extracted outside of recommended holding times, measurement uncertainties may be increased, and this should be taken into considerationwhen interpreting results.Where actual sampling date is not provided on the chain of custody, the date of receipt with time at 15:00 is used for calculation purposes.Where only the sample date without time is provided on the chain of custody, the sampling date at 15:00 is used for calculation purposes.Evaluation: û Holding time exceedance ; ü Within Holding TimeMatrix: Soil/SolidAnalyte GroupMethodExtraction / PreparationSampling DateContainer / Client Sample ID(s)PreparationDateHolding TimesRecActualAnalysisEvalAnalysis DateHolding TimesRecActualEvalMetals : High Silver in Soil/Solid by CRC ICPMSLDPE 3daysü24-Feb-2021166days0 24-Feb-2021166days0 eb-202114 days0 eb-202114 days0 eb-202114 days0 eb-202114 days0 eb-202114 days0 daysüMetals : High Silver in Soil/Solid by CRC ICPMSLDPE bagBA2107-A-8Metals : Mercury in Soil/Solid by CVAASLDPE bagBA2107-A-1Metals : Mercury in Soil/Solid by CVAASLDPE bagBA2107-A-10Metals : Mercury in Soil/Solid by CVAASLDPE bagBA2107-A-11Metals : Mercury in Soil/Solid by CVAASLDPE bagBA2107-A-12Metals : Mercury in Soil/Solid by CVAASLDPE bagBA2107-A-2
