Description:
Airborne measurements of scrubbed and unscrubbed plumes from the Widows Creek Steam Plant were made during August 17 to 25, 1978, under the SCRUB program. Data from the flight program (except size distribution data) and preliminary data analysis results have been previously published in a Data Volume. This report briefly describes the flight program and methodology of the SCRUB program and gives the results of the analysis of the data gathered during the flight program. The analysis results cover plume chemistry, primary aerosol, aerosol size distributions, and aerosol formation rates among the scrubbed and mixed plumes. Little difference was seen in photochemical aerosol and sulfate formation in the scrubbed and unscrubbed plumes. However, measurement noise and plume mixing may have obscured moderate differences. The submicron primary emissions from the scrubbed unit were only about 14 percent of those from the unscrubbed unit.
