Abstract Description: This study focuses on monitoring outdoor air quality in the Dalton West 148 School District, particularly in proximity to the district's train depot, using SENSIT Devices, SPODs, and RAMPs canister collections. The train depot, a significant source of activity and emissions, has been identified as a potential contributor to localized air pollution affecting nearby schools and the surrounding community.
SPODs were installed around the train depot and nearby school perimeters to provide continuous monitoring of particulate matter (PM2.5), nitrogen dioxide (NO2), and other key pollutants. Real-time data from these devices captured variations in air quality corresponding to train arrivals, departures, and idling periods. Complementing these, RAMPs collected canister samples at identified hotspots to provide detailed chemical analyses of pollutants, including hydrocarbons and diesel particulates, which are commonly associated with train operations.
Preliminary findings indicate elevated levels of PM2.5 and NO2 during peak train activity times, with pollutant concentrations highest within 500 meters of the depot. The RAMP canister analyses revealed elevated concentrations of benzene and toluene, indicative of diesel exhaust, raising concerns about prolonged exposure for students and staff in nearby schools. Seasonal variations were also observed, with higher pollutant levels during colder months when air tends to stagnate.
This study highlights the utility of combining SENSIT Devices, SPODs, and RAMPs canister collections for targeted outdoor air quality monitoring. The findings underscore the need for mitigative actions such as idling restrictions, buffer zones, and enhanced vegetation barriers around the train depot. By addressing air quality concerns in this high-impact area, the Dalton West 148 School District can better protect its students, staff, and community while contributing to broader environmental health initiatives. Future research will explore the effectiveness of these interventions and opportunities for community engagement.
