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

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.

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

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

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 dataWhat rigor is desired / monetarily feasible?

Will liability be an issue?

Summarize the purpose of your project

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

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 workAcceptable level of accuracy

Steps taken to develop a QAPP

Collect background and redefine the project History of the site

Sources of concernPrevious investigations / collected data

Site location and layoutGeography and weather

Watershed surveyAccess & safety concerns

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?

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? http://www.ars.usda.gov/is/np/fnrb/

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 dataReference and cite sources

Provide to the field crew as a manual of instructions

Page 14: QA/QC FOR ENVIRONMENTAL MEASUREMENT

Developed by: Zwiebel Updated: Jun. 27, 2005 U5-m13c-s14

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 implementationAvoids costly mistakes

Provide a final revised document to appropriate project stakeholders

Steps taken to develop a QAPP

Begin the monitoring program Implement the

project as tasked and scheduled

Evaluate and redefine the QAPP What does/ does not

work? Revise as needed
