Compton, Rancho Dominguez, Willowbrook, and Lynwood are neighboring communities in Los Angeles County, located within the South Coast Air Quality Management District-one of the most densely populated and air-polluted regions in the nation. Spanish is widely spoken, making bilingual outreach essential for effective community engagement.

Residents are exposed to significant air pollution from industrial facilities, heavy traffic, and major transportation corridors, resulting in elevated rates of asthma, cardiovascular disease, and other health disparities. Local organizations, together with the South Coast AQMD, have been implementing community air monitoring under Assembly Bill 617, aiming to guide future actions.

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 of 2025, community members and stakeholders from Compton, Rancho Dominguez, Willowbrook, and Lynwood met to discuss ongoing air quality challenges and explore collaborative solutions for a healthier future.
