1.0 INTRODUCTION In order for data to be used for decision-making purposes it is essential that it be of known and documented quality. Verification and validation of data requires that appropriate quality assurance and quality control (QA/QC) procedures be followed, and that adequate documentation be included for all data generated both in the laboratory and in the field. The QA/QC documentation provided by any laboratory, in conjunction with sample results, allows for evaluation of the following indicators of data quality: C C C C C C

Integrity and stability of samples;
Instrument performance during sample analysis;
Possibility of sample contamination;
Identification and quantitation of analytes;
Analytical precision; and
Analytical accuracy.

General laboratory documentation requirements discussed in this document are formatted into two sections, organic and inorganic analyses. These specifications are intended to establish general, analytical documentation requirements that contract and subcontract laboratories should meet when generating data for USEPA Region IX. However, project or contract requirements may supercede this document. In order to fulfill project specific objectives, laboratories may be required to supply additional documentation. Users should defer to project specific planning documents to determine if they are required to provide any additional information in deliverables. Questions or comments concerning this document should be directed to Carl Brickner, Jr., USEPA Region IX Quality Assurance Office, at (415) 744-1536 or brickner.carl@epa.gov.

2.0 GENERAL DOCUMENTATION REQUIREMENTS 2.1 Data Package Format

The data package submitted to EPA should consist of five sections: C C C C C

Case narrative;
Chain-of-Custody (COC) documentation;
Summary of results for environmental samples;
Summary of QA/QC results; and
Raw data.

Summaries of data and results may be presented in a Contract Laboratory Program (CLP) type format or any equivalent that supplies the required information as stated below. All laboratory data qualifiers shall be...
