What is the "flexible approach" for environmental measurement?
In 2008, EPA gauged its progress towards achieving the goals of PBMS, and redefined the steps needed to ensure continued progress. As a result of this analysis, the Agency now believes that while it may be possible to specify performance criteria in a manner that is independent of methods, techniques, or instruments, the development of a single protocol for the validation of all current and future measurements, including measurements made with techniques yet to be invented, is simply not possible. Accordingly, in February 2008 EPA introduced flexible approaches for environmental measurement which capture the Agency's experience of the past ten years and set the stage for future progress.
Key goals for these flexible approaches are as follows:
- Increased emphasis on flexibility in choosing sampling and analytical approaches to meet regulatory requirements for measurements.
- Development of processes for validation that confirm that measurements meet quality requirements.
- Increased collaboration with stakeholders to develop validation processes for new measurement technology.
- Rapid assessment of new or modified technologies, methods and procedures.
