Health Study Research & Data
A wealth of information and data on the Aliso Canyon blowout and gas storage facility operations exists. Below, please find a number of resources related to research and data that currently exists.
Environmental Reports, Sampling & Assessment Resources
Community Radiation Sampling
Public Health's Radiation Management team previously tested materials in waste bins from the Aliso Canyon blowout and well-control operations. The levels of radiation found were very low and within naturally existing background levels. These low levels of radiation do not pose an immediate health risk. Prior results are available below.
In response to requests from the community, Public Health's Radiation Management team is doing additional testing.
A virtual webinar was held on January 9 to present the draft sampling plan and address questions from residents of the northwestern neighborhoods of the San Fernando Valley. Additionally, feedback and recommendations on sampling locations were accepted from the community through January 30, 2023. The feedback was used to inform the selection of 10 additional sampling locations, bringing the total to 50 sampling locations. The final map of the sampling locations and the webinar materials are provided below.
If you have any questions, please contact the Public Health Radiation Management Team at DPHradiation@ph.lacounty.gov.
