Data Quality Assessment: A Reviewer's Guide (EPA QA/G-9R); EPA guide

摘要

This document is the 2006 version of the 'Data Quality Assessment: A Reviewers Guide' which provides general guidance to organizations on assessing data quality criteria and performance specifications for decision making. The Environmental Protection Agency (EPA) has developed a process for performing the Data Quality Assessment (DQA) Process for project managers and planners to determine whether the type, quantity, and quality of data needed to support Agency decisions have been achieved. This guidance is the culmination of experiences in the design and statistical analyses of environmental data in different Program Offices at the EPA. Many elements of prior guidance, statistics, and scientific planning have been incorporated into this document. This document is intended to be a 'living document' that will be updated periodically to incorporate new topics and revisions or refinements to existing procedures.
