	What are real-time measurement technologies? What is the Triad approach? What makes the Triad different from past efforts to improve the CERCLA process (the Observational Approach, Expedited Site Characterization (ESC), Data Quality Objectives (DQO), the Streamlined Approach for Environmental Remediation (SAFER), Superfund Accelerated Cleanup Program (SACM), etc.)? Is the Triad here to stay? What is the extent of regulatory acceptance of the Triad? What State regulatory agencies have bought into the Triad? What are field-based measurement technologies? How does the Triad differ from what I would traditionally do under CERCLA or RCRA? Why should I consider using the Triad for my project? Are there any situations where I should not use the Triad? What real-time measurement and/or field measurement techniques are currently available? How are real-time measurement systems related to the EPA Contract Laboratory Program and to the Superfund analytical method classification system?
