Chiquita Canyon Landfill

Located in the Santa Clarita Valley in northwestern Los Angeles County along State Route 126, it is owned and operated by Waste Connections.

The landfill stopped accepting trash at the end of 2024 after restrictions were placed on the operations due to ongoing smoldering chemical reaction in a portion of the site.

Oxygen may have intruded below the landfill cover causing the generation of extreme heat, production of excessive leachate, and the buildup of pressure within a 35-acre closed portion (14 ha) of the site.
