PM2.5 Monitoring

The Summit County Health Department (SCHD) conducted a four-month study of PM2.5 particulates in the Quinn’s Junction and Snyderville Basin areas of Summit County, Utah. Sampling was continuous over the span of 105 days at both sites running December 23, 2009 through April 12, 2010.

Results indicated generally low levels of PM2.5, with the exception of two days. During those two days, levels of PM2.5 were elevated due to dust storm events. The 24-hour mean concentrations of PM2.5 were lower at the Quinn’s Junction site (4.4 μg/m3) than at the Old Ranch Road site (5.5 μg/m3). The highest measured PM2.5 level was 44.9 μg/m3 recorded March 30, 2010 at the Old Ranch Road Site.
