Mira Loma, Jurupa Valley, Eastvale, and Pedley are diverse areas within Riverside County that include large Hispanic and Asian populations within the South Coast Air Quality Management District. These neighborhoods face significant pollution concerns from heavy truck traffic, major freeways, rail lines, and a high concentration of warehouses, leading to health issues like elevated asthma rates, especially in Jurupa Valley.

The district has teamed up with Aclima and the California Air Resources Board (CARB) to launch a community air monitoring project guiding future actions as a part of SMMI. Using Aclima’s advanced sensors, the project collects detailed, block-by-block data on air quality throughout the community. This provides residents with clear information about local pollution and helps guide actions to improve air quality, focusing on the areas and people most affected.

In April 2025, residents and stakeholders met to discuss air quality challenges and guide local air monitoring and pollution reduction efforts.
