QA/QC FOR ENVIRONMENTAL MEASUREMENT Unit 4: Module 13, Lecture 3
2
Developed by: ZwiebelUpdated: Jun. 27, 2005 U5-m13c-s2 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
Developed by: ZwiebelUpdated: Jun. 27, 2005 U5-m13c-s3 Quality Assurance Project Plans (QAPP) 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.

Developed by: ZwiebelUpdated: Jun. 27, 2005 U5-m13c-s4 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
Developed by: ZwiebelUpdated: Jun. 27, 2005 U5-m13c-s5 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
Developed by: ZwiebelUpdated: Jun. 27, 2005 U5-m13c-s6 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
Developed by: ZwiebelUpdated: Jun. 27, 2005 U5-m13c-s7 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
