EPA Region 10 SOP For the Validation of of Method 1668 Toxic, Dioxin-like, PCB Data (PDF) (15 pp. 39K, About PDF)
ABSTRACT
The Quality Assurance Unit of EPA Region 10 has developed the following guidelines which should be used to access the quality of toxic, dioxin-like PCB data from samples originating from Region 10 sampling sites. This SOP is based upon the data validation principles specified in National Functional Guidelines For Organic Data Review, December, 1990, and the quality control (QC) requirements of EPA Method 1668, Draft Revision, 10/4/95. The validator of toxic, dioxin-like PCB data should obtain a copy of the site-specific Quality Assurance Project Plan (QAPP) and
use the Data Quality Objectives and QA requirements of the QAPP to assess the data.
