SI1 Amended <br /> B <br /> Associates <br /> iaoeeraboxatories <br /> JJ Certificate of Analysis 01/27/2016 <br /> Notes: <br /> The Chain of Custody document and Sample Integrity Sheet are part of the analytical report. <br /> Any remaining sample(s)for testing will be disposed of one month from the final report date unless other arrangements are made in <br /> advance. <br /> Sample(s)received,prepared,and analyzed within the method specified criteria unless otherwise noted within this report. <br /> The results relate only to the samples analyzed in accordance with testis)requested by the client on the Chain of Custody document.Any <br /> analytical quality control exceptions to method criteria that are to be considered when evaluating these results have been fagged and are <br /> defined in the data qualifiers section. <br /> All results are expressed on wet weight basis unless otherwise specified. <br /> All positive results for EPA Methods 504.1 and 524.2 require the analysis of a Field Reagent Blank(FRB)to confirm that the results are not <br /> a contamination error from field sampling steps.If Field Reagent Blanks were not submitted with the samples,this method requirement has <br /> not been performed. <br /> Results contained in this analytical report must be reproduced in its entirety. <br /> Samples collected by BSK Analytical Laboratories were collected in accordance with the BSK Sampling and Collection Standard Operating <br /> Procedures. <br /> BSK Analytical Laboratories certifies thatthe test results contained in this report meet all requirements of the NELAC Standards for <br /> applicable certified drinking water chemistry analyses unless qualified or noted in the Case Narrative. <br /> Analytical data contained in this report may be used for regulatory purposes to meet the requirements of the Federal or State drinking water, <br /> wastewater,and hazardous waste programs. <br /> J-value is equivalent to DNO(Detected,not quantified)which is a trace value. A trace value is an analyte detected between the MDL and the <br /> laboratory reporting limit.This result is of an unknown data quality and is only qualitative(estimated).Baseline noise,calibration curve <br /> extrapolation below the lowest calibrator,method blank detections,and integration artifacts can all produce apparent DNO values,which <br /> contribute to the un-reliability of these values. <br /> (1)-Residual chlorine and pH analysis have a 15 minute holding time for both drinking and waste water samples as defined by the EPA and <br /> 40 CFR 136.Waste water and ground water(monitoring well)samples must be field filtered to meet the 15 minute holding time for dissolved <br /> metals. <br /> -This is not a NELAP accredited analyte. <br /> Summations of analytes(i.e.Total Trihalomethanes)may appear to add individual amounts incorrectly,due to rounding of analyte values <br /> occurring before or after the total value is calculated,as well as rounding of the total value. <br /> RL Multiplier is the factor used to adjust the reporting limit (RL)due to variations in sample preparation procedures and dilutions required for <br /> matrix interferences. <br /> The MCLS provided in this report(if applicable)represent the primary MCLs for that analyte. <br /> Definitions and Flags for Data Qualifiers <br /> mg/L: Milligrams/Liter(ppm) MDL: Method Detection Limit MDA95: Min.Detected Activity <br /> mg/Kg: MilligramstKilogram(ppm) RL: Reporting Limit:DL x Dilution MPN: Most Probable Number <br /> pg/L: Micrograms/Liter(ppb) ND: None Detected at RL CFU: Colony Forming Unit <br /> pg/Kg: Micrograms/Kilogram(ppb) pCi/L: Picocuries per Liter Absent: Less than 1 CFU/100mLs <br /> %: Percent Recovered(surrogates) RL Mult: RL Multiplier Present: 1 or more CFU/100mLs <br /> NR: Non-Reportable MCL: Maximum Contaminant Limit <br /> BS Blank spike recoveries did not meet acceptance limits. <br /> BS1.0 Blank spike recovery for this analyte was biased high;no material impact on reported result as sample is ND for this <br /> parameter. <br /> J Estimated value <br /> 0 AfA1316 FINAL 01272016 1420 <br /> Multiordecrpt <br /> 1414 Stanislaus St Fresno,CA,93706 559-497.2866 FAX 559465-6935 www.bskassociates.com <br /> An Employee-Owned Company I Analytical Testing I Construction Observation Page 6 Of 10 <br /> Environmental Engineering I Geotechnical Engineering I Materials Testing <br />
