Respective batch quality, LCS is acceptable therefore data has been flagged and reported accordingly. Method 218.7: Due to sample being slightly acidic and the compounds of concern not being stabalized at a pH >8 for 24hrs, MW- 4 has been flagged as analyzed outside method recommended holding time. Radiological: Please note that the following samples have higher activity counts for radium226 or 228 as compared to historical trends-MW19D, MW18D, CW6. Metals via ICPMS: The matrix spike and spike duplicate associated with MW2 and MW4 recovered below method recommended limits for low level thallium. Respective batch quality including LCS was acceptable, there is no adverse impact on data. The instrument calibration blank associated with this dataset recovered above the detection blank for low level vanadium but below the reporting limit. Data has been flagged accordingly. Data Flags & Calculations: Any analytical tests or individual analytes within a test flagged with a Qualifier indicate a deviation from the method quality system or quality control requirement. The qualifier description is found at the end of the Certificate of Analysis (sample results) under the qualifiers heading. All results are reported on a dry weight basis unless otherwise noted. Subcontracted data included on the Duke Certificate of Analysis is to be used as information only. Certified vendor results can be found in the subcontracted lab final report. Duke Energy Analytical Laboratory subcontracts analyses to other vendor laboratories that have been qualified by Duke Energy to perform these analyses except where noted. Data Package: This data package includes analytical results that are applicable only to the samples described in this narrative. An estimation of the uncertainty of measurement for the results in the report is available upon request. This report shall not be reproduced, except in full, without the written consent of the Analytical Laboratory. Please contact the Analytical laboratory with any questions. The order of individual sections within this report is as follows: Job Summary Report, Sample Identification, Technical Validation of Data Package, Analytical Laboratory Certificate of Analysis, Analytical Laboratory QC Reports, Sub-contracted Laboratory Results, Customer Specific Data Sheets, Reports & Documentation, Customer Database Entries, Test Case Narratives, Chain of Custody (COC) Certification: The Analytical Laboratory holds the following State Certifications : North Carolina (DENR) Certificate #248, South Carolina (DHEC) Laboratory ID # 99005.
