QA/QC Procedures Sample Clauses

QA/QC Procedures. Describe the Prime Consultant’s proposed Quality Assurance / Quality Control approach with emphasis upon how it will be accomplished on multiple concurrent Task Order Assignments having different Task Managers.

QA/QC Procedures. The NAEMS researchers followed QA/QC procedures throughout the data collection and preliminary data analyses processes. The NAEMS researchers developed QAPPs, SOPs for sampling systems and monitoring instruments and site-specific monitoring plans (SMPs) and provided training for on-site operators and producers. Appendix A contains the QAPPs, Appendix B contains the SMPs for each monitoring site and Appendix C contains the SOPs. Remote sensing instruments, synthetic open-path sampling systems, and gas analyzers underwent initial and periodic calibration, bias and precision checks and were corrected if they failed the QC checks. The frequency of each check/calibration event was dependent on the type of instrument and on the site investigators. For example, the calibration checks were conducted daily, at the beginning and end of each measurement period, every 180 days at Purdue Air Monitoring Lab (PAML), annually or a combination of these intervals. All of the monitoring sites were equipped with data acquisition (DAQ) systems that allowed on-site operators, and other authorized personnel via high-speed Internet connection, to view the measured data and parameter values daily through real-time computer displays. The DAQ systems also generated email notifications for project personnel when monitored parameter values were outside of preset ranges. The NAEMS researchers also used control charts extensively in QA/QC procedures to assess data quality and measurement variability and to evaluate long-term trends in the instrument/equipment performance. The control charts provided a graphical means of determining whether the measured parameters were within acceptable upper and lower control

QA/QC Procedures. A. The Contractor shall maintain a QA/QC plan for each analytical facility and shall follow the SOPs contained or referenced in the plan. B. The Contractor shall maintain a full-time quality assurance officer at each Lab location analyzing City-submitted samples. C. Contractor must provide a copy of their Quality Manual, Organizational Chart, and most recent Performance Evaluation Studies upon request by the City. D. Contractor may be requested to participate in the EPA Discharge Monitoring Report-Quality Assurance Study Program. Such participation and reporting will be done without fee to the City.

QA/QC Procedures. Quality assurance and quality control (QA/QC) for sampling processes will include proper collection of the samples in order to minimize the possibility of contamination. All samples will be collected in laboratory supplied, laboratory-certified, contaminant free sample bottles. Field staff will wear powder-free nitrile gloves (or similar) at all times during sample collection. All sampling personnel will be trained according to field sampling SOPs. Additionally, the field staff will be made aware of the significance of the project’s detection limits and the requirement to avoid contamination of samples at all times. A temperature blank will be used to ensure sample holding temperatures were maintained from sample collection through delivery to the laboratory, and equipment rinse blanks will ensure cross contamination from equipment to the water sample has not occurred. Duplicate samples will also be analyzed to assess variability in sampling and to remain compliant with Surface Water Ambient Monitoring Program protocols. Each batch of samples that is submitted to the laboratories for analyses will be accompanied by an equipment rinse blank, field blank, and a duplicate sample, as specified under Surface Water Ambient Monitoring Program (SWAMP). Samples will be analyzed by a laboratory certified by the California Environmental Laboratory Accreditation Program (ELAP) for the analyses of inorganics, toxic chemical elements, and organics in wastewater. Field measurements for pH, conductivity, and temperature will be made using an Oakton CON10 pH/temperature/conductivity water quality probe or similar probe according to the manufacturer’s specifications. Calibration of the instruments will be conducted prior to each sampling event.

QA/QC Procedures. ‌ The overall QA objective for measurement data is to ensure that data of known and acceptable quality are provided. All measurements will be made to yield accurate and precise results representative of the media and conditions measured. QA objective for precision, accuracy, and completeness have been established for each measurement variable, where possible. An accredited laboratory with a documented quality assurance program will provide chemical analytical services for the project. The selected laboratory will be required to have and maintain an internal QA program, documented in their laboratory QA manuals. The selected laboratory will use a combination of blanks, surrogates, duplicates, matrix spike/matrix spike duplicate (MS/MSD), and laboratory control samples blank spike/blank spike duplicate (BS/BSD) to demonstrate analytical QA/QC. The laboratory will be required to have established control limits for individual chemicals or groups of chemicals based on the long-term performance of the test methods. The specific procedures to be completed for this project are identified in Table 1.

QA/QC Procedures. 3.8.1 All tests must be conducted by laboratories accredited by Hong Kong Laboratory Accreditation Scheme (HOKLAS) or, in case of overseas laboratories, by equivalent national accreditation for these tests.

QA/QC Procedures. QA and QC representatives will provide oversight of site conditions and workmanship at all times during the task. The QA rep (IGSATR) will evaluate the COH’s performance under this agreement, and will record all observations.
