This manual is designed to delineate the routine operation of the US EPA Region 4 Analytical Support Branch and to describe the Branch's Quality System. The policies in this manual are intended only for the Analytical Support Branch. While the policies may be informative for other laboratories, they may not be directly applicable to operations in other laboratories. The primary purpose of this document is to establish and maintain uniform operational and quality control guidance for regional analytical chemistry activities and quality assurance/quality control activities. The establishment of, and adherence to, uniform elements of an intralaboratory quality control program are essential to the production of reliable analytical data.
This manual and the quality control protocols described herein are not to be viewed as all inclusive. Rather, they serve as a basic foundation on which to build a stronger quality assurance program within the Branch. Methodologies and some quality assurance documents are included by reference.
