ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA Method 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes. TNI - The NELAC Institute. ANALYTE QUALIFIERS The recalculated concentration of the calibration standard(s) did not meet method acceptance criteria; this result should be considered an estimated value.IK This analyte exceeded secondary source verification criteria low for the initial calibration. The reported results should be considered an estimated value.IL Analyte recovery in the laboratory control sample (LCS) was below QC limits. Results for this analyte in associated samples may be biased low.L2 Matrix spike recovery and/or matrix spike duplicate recovery was outside laboratory control limits.M0 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.M1 The lab does not hold NELAC/TNI accreditation for this parameter but other accreditations/certifications may apply. A complete list of accreditations/certifications is available upon request.N2 RPD value was outside control limits.R1 The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the associated samples may have a high bias.v1 The continuing calibration verification was below the method acceptance limit. The analyte was not detected in the associated samples and the sensitivity of the instrument was verified with a reporting limit check standard.v2 The continuing calibration verification was below the method acceptance limit. Any detection for the analyte in the associated samples may have low bias.v3 REPORT OF LABORATORY ANALYSIS This report shall not be reproduced, except in full, without the written consent of Pace Analytical Services, LLC.Date: 07/11/2022 05:11 PM Pace Analytical Services, LLC 9800 Kincey Ave. Suite 100 Huntersville, NC 28078 (704)875-9092 Page 35 of 39 #=CR# QUALITY CONTROL DATA CROSS REFERENCE TABLE Pace Project No.: Project: 92611578 LSG-001 Lab ID Sample ID QC Batch Method QC Batch Analytical Method Analytical Batch 92611578001 824633 825275SP-2 EPA 3050B EPA 6020B 92611578002 824633 825275DUP-2 EPA 3050B EPA 6020B 92611578001 824638 825249SP-2 EPA 7471B EPA 7471B 92611578002 824638 825249DUP-2 EPA 7471B EPA 7471B 92611578001 706843 707404SP-2 EPA 3546 EPA 8270E 92611578002 707334 707583DUP-2 EPA 3546 EPA 8270E 92611578001 706927 707067SP-2 EPA 5035A/5030B EPA 8260D 92611578002 706927 707067DUP-2 EPA 5035A/5030B EPA 8260D 92611578001 706844SP-2 SW-846 92611578002 706844DUP-2 SW-846 REPORT OF LABORATORY ANALYSIS This report shall not be reproduced, except in full, without the written consent of Pace Analytical Services, LLC.Date: 07/11/2022 05:11 PM Pace Analytical Services, LLC 9800 Kincey Ave. Suite 100 Huntersville, NC 28078 (704)875-9092 Page 36 of 39 Page 37 of 39 Page 38 of 39 06/29/22 Technical Report for Hart & Hickman LSG-001 LSG-001 SGS Job Number: JD47350 Sampling Date: 06/23/22 Report to: Hart & Hickman 2923 South Tyron Street Suite 101 Charlotte, NC 28217 SCottrill@harthickman.com ATTN: Shannon Cottrill Total number of pages in report: Certifications: NJ(12129), NY(10983), CA, CT, FL, IL, IN, KS, KY, LA, MA, MD, ME, MN, NC, OH VAP (CL0056), AK (UST-103), AZ (AZ0786), PA(68-00408), RI, SC, TX, UT, VA, WV This report shall not be reproduced, except in its entirety, without the written approval of SGS.
