This report details a collaboration between the San Diego State University Graduate School of Public Health’s Spring 2017 PH 632 Air Quality course, the Sage Project, and the City of Lemon Grove. The studies contained in this report were designed to provide the City of Lemon Grove with data regarding humidity, noise levels, and ambient air quality and to assess the usability of certain areas of the city. This report covers four ambient air and noise sampling studies in Lemon Grove performed by four graduate student groups. Their purpose was to determine whether the residents of Lemon Grove were exposed to excessive ambient concentrations of particulate matter (PM) as well as excessive ambient noise levels. Multiple PM2.5 mass concentration and particle count measuring devices were used. Instruments that measure ambient noise, relative humidity, and temperature were also used.
