In October 2015, a natural gas leak was discovered at the Aliso Canyon Storage Field. Odors affecting residents in the Porter Ranch area have been reported to the Los Angeles County Department of Public Health.


Natural gas contains components such as methane and mercaptans, which could cause a health threat to people and animals. Health information on the effects of the leak to human health can be found here.


For updated information on the situation at Porter Ranch, please visit the website of our Environmental Health Program or call their customer center at: 888-700-9995.





Just like people, animals may also become sick from increased contact with some compounds found in natural gas. At this point, little is known of the effects of the on-going gas leak on animals.

If you live in the area affected by the leak please keep your pets indoors. If you notice any of the following in your animals, please contact your local veterinarian:

  • Difficulty breathing

  • Vomiting

  • Lethargy

  • Nausea


Leaving the area of the leak may reduce the adverse effects of the natural gas in people and animals.
