Goal: Identify characteristic pollutant mixtures within communities impacted by unique pollutant sources including non-roadway transportation sources, point emission sources and localized burn events. Approach: Develop a mobile air quality monitoring infrastructure and deployment strategy allowing for the long-term gathering of information on pollutant mixtures and trends impacting Washington communities. This mobile air quality monitoring is not intended to provide regulatory data. Mobile monitoring has been shown to effectively represent annual concentrations of air pollutant when sampling design is balanced over the course of a year. Mobile monitoring has also been demonstrated to allow for discrimination of distinct pollutant sources including roadway traffic, non-roadway transportation sources and local point sources. A mobile sampling platform has the advantage of spatial flexibility, rapid response to ambient air quality concerns and ability to capture a range of pollutants including novel measures not currently captured by the ambient air quality monitoring. Scope: This budget request includes the two components. The first, includes the hardware required to acquire and custom assemble 2 mobile monitoring platforms. The ability to simultaneously sample at 2 locations is critical to interpreting mobile monitoring data and spatial extent of air pollution impacts. The second, the development and testing of a mobile monitoring sampling protocol developed by the Department of Environmental and Occupational Health Sciences at the University of Washington in partnership with local, State and Federal stakeholders. Outputs: The output of this project will include • 2 fully equipped mobile monitoring platforms, ready for installation in commercially available hybrid SUV vehicles.…

We would also like to thank Estela Ortega, El Centro de la Raza and U.S.EPA Region 10 for providing the funds to support our summer interns (USEPA Problem Solving Collaboration 01J27101 Community Empowerment Grant). And, a big thanks to all the Beacon Hill residents who volunteered to host a noise measurement device at their home. This project was possible because of the work of the Beacon Hill volunteer community. Introduction The overarching goal of the project was to conduct Citizen Science measurements with University of Washington undergraduate student summer interns paid by El Centro de la Raza to help residents collect noise measurements. The project aimed to empower residents to collect new noise measurement data, which may benefit future follow-up activities, including collecting additional measurements, improving community awareness of noise levels, and follow-up research by others to quantify relationships to potential noise sources and health impacts. This is the first project to collect quality…
