  1. QA/QC FOR ENVIRONMENTAL MEASUREMENT Unit 4: Module 13, Lecture 3

  2. Objectives • Introduce Quality Assurance Project Plans (QAPPs) • What is a QAPP? • Why is it necessary? • Explain the processes to take when developing a QAPP • Eight steps • Discuss in detail elements to consider and include when developing a QAPP • 24 elements

  3. QAPP guides: the selection of parameters and procedures data management and analysis steps taken to determine the validity of specific sampling or analysis procedures The QAPP outlines the QC measures to be taken for the project. The QAPP is a project-specific QA document. Quality Assurance Project Plans (QAPP)

  4. QA for environmental measurement • Why do we need quality assurance for environmental measurement? • understand data reliability • quantify areas of analytical uncertainty • standardize measurement to allow for repeatable and comparable data across time and place QA ensures that data will meet defined standards of quality with a standard level of confidence

  5. Elements of a QAPP • QAPP can be broken out into four areas of the project • Project management • Measurement and data acquisition • Assessment and oversight • Data validation and usability

  6. Establishing a QAPP • What do you first do when establishing a QAPP? • Consider the purpose of the investigation • Compliance vs. background data, etc. • Consider who is funding the investigation and who will use that data • What rigor is desired / monetarily feasible? • Will liability be an issue? Summarize the purpose of your project

  7. Steps taken to develop a QAPP • Establish a QAPP team • Determine project goals & objectives • Collect background • Determine project data requirements • Develop implementation plans • Develop SOPs • Draft the QAPP, solicit feed back, revise and submit for approval • Begin the project, evaluate and redefine QAPP

  8. http://oceanexplorer.noaa.gov/explorations/02hudson/logs/aug29/aug29.htmlhttp://oceanexplorer.noaa.gov/explorations/02hudson/logs/aug29/aug29.html Steps taken to develop a QAPP • Establish a QAPP team • Include project stakeholders • technical expertise in varying areas of the project • Approval required by the governing agency? • review agency website • guidance document(s)

  9. Steps taken to develop a QAPP • Determine goals and objectives • Why is the program being conducted? • Compliance • Gathering background • How will the information gathered be used and who will use it? • Identify all potential data users • Will collected data be considered useable, and to what extent? • Comparable to previous work • Acceptable level of accuracy

  10. http://www.tfhrc.gov/pubrds/novdec98/seven.htm Steps taken to develop a QAPP • Collect background and redefine the project • History of the site • Sources of concern • Previous investigations / collected data • Site location and layout • Geography and weather • Watershed survey • Access & safety concerns • Hazards • Natural • Manmade

  11. Steps taken to develop a QAPP • Design project sampling, analytical and data requirements • What parameters will be monitored? • How accurate will the data need to be? • What are the Data Quality Objectives (DQOs)? • Where will samples be collected and how will sites be chosen? • When will sampling be implemented? • What protocols will be used? • How will data credibility be assured?

  12. http://www.ars.usda.gov/is/np/fnrb/fnrb1001.htm Steps taken to develop a QAPP • Develop implementation plans • Who will carry out the project tasks? • Sampling, data management / evaluation, etc. • When will the tasks be conducted? • How much time will be allotted for each? • Final report to be generated?

  13. Steps taken to develop a QAPP • Adopt or develop project-specific Standard Operating Procedures (SOPs) • Use “industry” existing SOPs when possible • Consistency and usability of data • Reference and cite sources • Provide to the field crew as a manual of instructions

  14. Steps taken to develop a QAPP • Draft the QAPP, solicit feedback, and submit for final approval • Use formats provided by the governing agency or client • Generate a draft document and solicit feed back from agency or client prior to implementation • Avoids costly mistakes • Provide a final revised document to appropriate project stakeholders

  15. Begin the monitoring program Implement the project as tasked and scheduled Evaluate and redefine the QAPP What does/ does not work? Revise as needed http://ma.water.usgs.gov/CapeCodToxics/photo-gallery/wq-sampling.htm Steps taken to develop a QAPP
