Lost Hills is a small, predominantly Hispanic farmworker community in western Kern County, within the San Joaquin Valley Air Pollution Control District. Lost Hills is surrounded by major pollution sources, including one of California’s largest oilfields, industrial agriculture, highways, and processing plants, resulting in high rates of asthma, cardiovascular disease, and low birth weight. Local groups like Clean Water Fund have led air quality monitoring and advocacy, partnering with agencies 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, residents and stakeholders met to discuss air quality concerns and work toward a healthier future.
