Principles and Practices for Quality Assurance and Quality Control

Open-File Report 98-636
Prepared in cooperation with the Federal Highway Administration (A Contribution to the National Highway Runoff Data and Methodology Synthesis)



Quality assurance and quality control are vital parts of highway runoff water-quality monitoring projects. To be effective, project quality assurance must address all aspects of the project, including project management responsibilities and resources, data quality objectives, sampling and analysis plans, data-collection protocols, data quality-control plans, data-assessment procedures and requirements, and project outputs. Quality control ensures that the data quality objectives are achieved as planned. The historical development and current state of the art of quality assurance and quality control concepts described in this report can be applied to evaluation of data from prior projects.
