Los Angeles County has filed a lawsuit against the owners of Chiquita Canyon Landfill in Castaic, accusing them of failing to contain a noxious smell that has been plaguing neighbors for nearly two years.
Local and federal officials say the stench emanates from an underground fire smoldering within the landfill’s trash and creating a “reaction event” from gases and liquids.
Nearby residents have complained of health issues, including headaches, nausea, eye, nose and throat irritation and vomiting.
“These odors last for hours at a time – in some cases for more than twelve hours – wreaking havoc on the quiet enjoyment of these residential communities and rendering many outdoor activities unbearable,” the lawsuit alleges.
State officials are also investigating if the fumes have led to a cluster of cancer cases.
The county’s lawsuit is seeking an injunction to “halt the noxious emission” and force the landfill’s owners, Waste Connections, to pay to relocate residents until the smell is contained temporarily.

“This lawsuit is a necessary step to ensure accountability and compliance with the rules that protect our residents and the environment,” said County Supervisor Kathryn Barger. “We must hold the responsible party accountable and continue doing everything possible to restore safe and healthy living conditions for our communities.”
KTLA has reached out to the Waste Connection for a response to the lawsuit. Managers have insisted that they are “working cooperatively” with regulatory agencies to address the issues.
“Chiquita takes very seriously its role in the safe operation of the landfill,” a statement in December 2023 read.
