Imperial County Community Air Monitoring Project
home >  projects
This innovative project established the first large-scale community air monitoring network of its kind, serving as a model for projects throughout California and informing the implementation of statewide legislation on community air monitoring.

In Imperial County, CA where particulate pollution often exceeds state standards for more than six months at a time, and children have among the highest rates of asthma-related emergency room visits and hospitalizations in the state, the availability of real-time, local air quality information can be a life or death issue. 


In response, Tracking California worked with partners (Comite Civico del Valle, University of Washington, and others) and local residents to establish a community air monitoring network of 40 particulate matter (PM) monitors. The real-time air monitoring data are now available online and are being used by schools, residents, and agencies to understand and reduce exposures to air pollution.  Lessons from this project are described in the Guidebook for Developing a Community Air Monitoring Network: Steps, Lessons, and Recommendations from the Imperial County Community Air Monitoring Project.
