A comprehensive, five-year study to understand the health consequences of the nation’s largest uncontrolled release from a single underground gas storage facility in US history.
In November 2022, a team of UCLA researchers was awarded a $21 million grant by the Los Angeles County Department of Public Health to conduct the Aliso Canyon Disaster Health Research Study.
The purpose of the Health Study is to assess short- and long-term effects of the disaster and routine emissions on the health of communities living and working in proximity to the blowout.
It is a comprehensive assessment comprising multiple studies that together will form a full picture of the impact of exposure to the emissions on people’s health. These include studies of environmental exposures and studies of health and well-being.

We have brought together a team of the world’s best scientists to investigate the environmental and health impact of the facility, including physical and mental health, quality of life, and overall well-being throughout their life course...The outcomes of these studies will be exceptionally important and also at times, very complex. We will present these findings in a clear and approachable way to provide the information needed by residents, regulators, and policymakers to understand the disaster impacts and take actions when needed.
