PERFORMANCE-BASED MEASUREMENT SYSTEMS - ENSURING DATA DEFENSIBILITY
Citation:
Brilis, G M. PERFORMANCE-BASED MEASUREMENT SYSTEMS - ENSURING DATA DEFENSIBILITY. Presented at Association of Environmental Health Sciences and US Navy Eleventh Annual West Coast Conference, San Diego, CA, March 19-22, 2001.
Impact/Purpose:
The overall objective of this task is to provide the Agency with improved science guidance and strategies for more effective science management and administration.
Description:
The use of established methods for the analysis of environmental samples procedures has been one factor that courts have used to determine if the science use in the analysis is adequate for the purposes intended. This established "comfort-zone" may be shaken by efforts to approve and use alternate methods.
The Environmental Protection Agency (EPA) is actively working to reform the regulatory policy. As part of this program, EPA has been working at breaking down barriers to using new monitoring techniques. One barrier is the requirement to use specific measurement methods or technologies in complying with some of the Agency's regulations. There is broad acceptance for Agency-wide use of a nonprescriptive performance-based measurement system (PBMS).
The evaluation of the method used, the review of results generated by that method and the veracity of the data may be required to undergo a more rigorous evaluation. In this presentation, the author describes PBMS, the intent of PBMS, and outlines a procedure for investigators to use when considering analytical results generated using the PBMS.
