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:
• 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.
