We aim to assess the ambient air quality and potential emissions outdoors and at residences near the Aliso Canyon facility. This newly collected data will help us better characterize any potential ongoing emissions, how those emissions may travel through air, and where those emissions travel within the community.

The Study includes indoor air quality monitoring of emissions that could occur during natural gas appliance usage and from other pollution sources. Specifically, we aim to identify any potentially harmful chemicals present in the gas supplied to homes near the Aliso Canyon facility. In addition, we will collect gas samples directly from pipes that transport gas to residences to gain insight into gas composition before it is used.

These steps will afford a more holistic understanding of the potential sources of exposures associated with the natural gas facility.
