Verification and Validation Methods. The majority of test and calibration data are reviewed and verified manually from data forms and calibration sheets. Verification of test data that are entered into the ETIS database is a manual review of transcribed data. Personnel responsible for data entry verification/validation are given in AE SOP 4.15.2. ETIS contains features that will alert the user to data that exceed CFR requirements or equipment calibration limits. Data that are determined to be out of limits are verified for correct entry otherwise the data are a test nonconformance. QA for PM sample filters is assisted by FRIS. The software will alert the user to filter conditioning data, checkout time, or reference filter weight changes that exceed CFR requirements. Filter data that are determined to be out of limits are test nonconformances.
Verification and Validation Methods. Data collected in the field will be validated and verified by the Project QA Officer. Reconciliation and correction will be the responsibility of the Project Director. Laboratory validation and verification of the data generated is the responsibility of each laboratory. Each laboratory supervisor maintains analytical reports in a database format as well as all QA/QC documentation for the laboratory. The Project Director is responsible for oversight of data collection and the initial analysis of the raw data obtained from the field and the contracted laboratory. The Project Director responsibilities also include the generation of rough drafts of quarterly and final reports. The Project Director has final oversight on the submission of quarterly and final reports.
Verification and Validation Methods. D2.1 Data Verification Data verification includes checking that results have been transferred correctly from the original hand-written, hard copy field and analytical laboratory documentation to the project databases. The goal of data verification is to identify and correct data reporting errors. For analytical laboratories that utilize the Xxxxx-specific EDD spreadsheets, data checking of reported analytical results begins with automatic QC checks that have been built into the spreadsheets. In addition to these automated checks, a detailed manual data verification effort will be performed for 10% of all samples and TEM analytical results collected as part of this sampling effort. This data verification process utilizes Site-specific SOPs (see Appendix B) developed to ensure TEM results and field sample information in the project databases is accurate and reliable: ▪ EPA-XXXXX-09 – SOP for TEM Data Review and Data Entry Verification – This Site-specific SOP describes the steps for the verification of TEM analyses, based on a review of the laboratory benchsheets, and verification of the transfer of results from the benchsheets into the project database. ▪ EPA-XXXXX-11 - SOP for FSDS Data Review and Data Entry Verification – This Site-specific SOP describes the steps for the verification of field sample information, based on a review of the FSDS form, and verification of the transfer of results from the FSDS forms into the project database. An FSDS review is performed on all samples selected for TEM or PLM data verification. The data verification review ensure that any data reporting issues are identified and rectified to limit any impact on overall data quality. If issues are identified during the data verification, the frequency of these checks may be increased as appropriate. Data verification will be performed by appropriate technical staff that are familiar with project- specific data reporting, analytical methods, and investigation requirements. The data verifier will prepare a data verification report (template reports are included in the SOPs) to summarize any issues identified and necessary corrections. A copy of this report will be provided to the appropriate project data manager, LC, and the EPA RPM. The data verifier will also transmit the results of the data verification, including any electronic files summarizing identified discrepancies, via email to the EPA Region 8 data manager (Xxxxx.Xxxxxx@xxx.xxx) for resolution. A follow-up email will be...
Verification and Validation Methods. D.2.1 Documentation, Data Reduction and Reporting Documentation will include the sampling reports, copy of the chain-of-custody, and field QA controls with the analytical results. Data reduction will occur in accordance with the laboratory’s analytical SOPs for each parameter. If difficulties are encountered during sample analyses, a brief description of the problem will be provided. Data derived from sampling events undertaken for projects under the oversight of the BVCP will be reported to the BVCP Project Manager as discussed in Section C.2. Reports to Management.
Verification and Validation Methods. All data records will be checked visually prior to data entry into either the CCAMP database or other electronic formats. Any corrections will be written directly on the datasheet. VMP staff will conduct all reviews and the MBNEP’s QA Officer will review all datasheets and all data entry into CCAMP and other electronic formats. Laboratory QA Officers will perform checks of all of their records. All submittals by laboratories will be reviewed by the MBNEP Program Manager. Any questions with the data submitted by the laboratories will be addressed with the appropriate laboratory personnel who verify the data. Once any issues have been resolved, the data can be loaded into the CCAMP database and other electronic formats. Data validation is conducted by the MBNEP QA Officer and is done by a manual review of the data. The MBNEP QA Officer is responsible for verifying and validating all datasheets, chain of custody forms, maintenance logs and calibration logs. The MBNEP QA Officer also validates the data entry into the CCAMP database and other electronic formats, as well as any calculations. Issues will be noted. Reconciliation and correction will be done by a committee composed of the MBNEP QA Officer and VMP staff with input, if applicable, from laboratory directors and from the RWQCB QA Officer. Any special notes on decisions regarding data usability will be entered in the ‘Notes’ column of the CCAMP database. If it has been determined that the data should not be used in future calculations, it will be flagged as such in the electronic format.
