Data Quality Indicator Tables

The following tables list the EPA Region 9 quality control acceptance criteria for selected laboratory analytical methods. Region 9 has developed these specifications to ensure that laboratory-generated analytical data is of acceptable quality for use in environmental decision making. For more information on the Region 9 data review procedures, please see the Data Validation page.

The following Data Quality Indicator Tables are available in PDF format. Revisions (indicated in bold) and WordPerfect versions of these tables may be obtained by contacting the Region 9 QA program.
