  1. Issues with Continuous Mercury Monitoring Data Utility MACT W. G. Meeting Washington, DC March 4, 2003

  2. “Longer-Term” Sampling Sites

  3. Test 1 • Two identical measurement systems. • Downstream cold-side ESP. • Sampling probes ~ 3 ft apart. • Operated ~72 hours.

  4. Test 2 • One sampling system, two Hg analyzers. • Otherwise identical to Test 1.

  5. Future Activities/Research • Complete analysis of parametric SCEM data. • Improve understanding of root causes of “spurious” signals. • Determine if feasible to eliminate or at least mitigate such instrument responses.
