Vapor hisses from floor fissures. Effervescent ponds of effluent kind “rivers of odorous waste.” And at instances, steaming scorching liquid bursts into the air like a geyser.
As operators wrestle to include a smoldering fireplace and stress buildup deep inside Chiquita Canyon Landfill, air high quality regulators are elevating alarms over the potential well being dangers posed by the poisonous fumes escaping the Castaic facility.
Environmental regulators say that the native air and water samples have contained elevated ranges of benzene, a cancer-causing chemical that evaporates simply. In addition they have reprimanded Waste Connections, the landfill’s proprietor, for failing to report the leaks after they first occurred and for not offering space residents with air high quality information.
“The landfill operator is already gathering a lot of this air air pollution info, however it isn’t being launched to the group in a manner that lets residents make knowledgeable decisions to guard their very own well being,” stated Jeff Lindberg of the California Air Assets Board.
The gasoline and water leaks are being pushed by a uncommon chemical response that has generated scorching warmth and intense stress inside a 35-acre portion of the landfill. South Coast Air High quality Administration District officers have described the situations as virtually volcanic and, in latest months, a white vapor has been noticed hissing by way of lengthy cracks within the face of the response zone.
The disaster has renewed calls to close down the ability and prompted the U.S. Environmental Safety Company to step in and oversee efforts to include the rising downside. It was additionally the middle of debate throughout two days of testimony and public feedback at a latest air district assembly.
Throughout these discussions, air high quality regulators argued that the landfill’s efforts to take away leaking wastewater had been insufficient and famous that the landfill had no plans to eliminate the foul water on Sundays or some holidays. The company additionally stated that the landfill’s quarterly air monitoring studies failed to offer the general public with real-time info for locals to guard themselves.
A roughly 35-acre portion of Chiquita Canyon Landfill is smoldering, inflicting polluted water to spill out onto the western and northern fringe of the positioning.

“We now know that this …[leakage] is a big think about contributing odors, particularly within the Val Verde space,” stated Larry Israel, an air district inspector. “These residents are complaining nonstop, 24 hours a day about odors, and our considering is we have to cease this as quickly as attainable. They’re being closely impacted.”
For his or her half, Chiquita Canyon operators informed regulators that they had been dedicated to fixing the issue.
“Everybody on this room desires the identical factor: to gradual and cease this response and scale back the impacts to the group,” stated Megan Morgan, an legal professional representing the landfill. “Chiquita could not expertise this challenge in the identical manner that its neighbors do, however Chiquita and its staff are there on-site every day working laborious as they’ll to handle this challenge.”
Chiquita Canyon workers have constructed wells to extract liquids and gases which are fueling the smoldering situations. They’ve put in a flare to burn off flammable gases, together with methane, which has been detected at explosive ranges on the landfill’s perimeter. They’ve additionally added soil to restore cracks the place gases and liquids have been seeping out, operators stated.
In response to the regional water board, Chiquita Canyon has been disposing of round 2- to 4-million gallons of contaminated water a month for a lot of the previous yr. That water was made up of a mix of hazardous spills and the landfill’s efforts to proactively extract wastewater to alleviate pent-up stress, in keeping with the Los Angeles Regional Water Board.

1. Contaminated water has seeped out of Chiquita Canyon Landfill in Castaic, forming streams of odorous waste and fumes. 2. The polluted water oozing out of Chiquita Canyon incorporates cancer-causing benzene and different chemical substances, which environmental regulators concern is vaporizing and drifting into close by communities.
Thus far, the wastewater has not migrated offsite, the place it might pose a risk to native groundwater or streams. Nonetheless, the spills started to develop bigger final fall, when a concrete-lined stormwater channel on the perimeter of the landfill managed to seize the waste, officers stated.
The primary canyon, the place rubbish is burning, has a backside liner that serves as an impermeable barrier to make sure water air pollution doesn’t filter deeper underground into native aquifers. Though some fear the liner might have been broken, there’s no proof it has been compromised, officers stated.
Steaming-hot, contaminated water has additionally surged to the floor, oozing out of fissures. These hazardous spills have fashioned effervescent ponds and “in the end rivers of odorous waste,” in keeping with officers with the SCAQMD. At instances, this polluted water has erupted with such power that it has shot into the air “like a geyser.”
Air district officers reprimanded Waste Connections for failing to right away report these incidents. Though Chiquita Canyon representatives not too long ago acknowledged these hazardous spills have been occurring since mid-2022, they didn’t inform the air district that wastewater was spilling onto the floor till October.
Following testimony on the difficulty, the air district’s listening to board accredited a litany of necessities meant to handle the polluted water and nauseating fumes.
Amongst different necessities, Chiquita should now take away wastewater seven days every week and should present real-time air high quality information from two of its group monitoring stations, one in Val Verde and one other in Hasley Canyon Park in Castaic.
The air district famous the wastewater from spills and gasoline samples contained elevated ranges of benzene. On Oct. 7, the landfill’s group air monitoring at Hasley Canyon Park detected benzene at 69.5 components per billion, greater than eight instances the state well being restrict for short-term publicity.
The landfill obtained these ends in early November, however its representatives didn’t inform the air district till weeks after, in keeping with Stephen Dutz, an air high quality chemist with the district.
The brand new necessities adopted remarks from a number of individuals who reside close to the landfill — together with Sarah Olaguez, whose house is due north of the ability.
“The board and the legal professionals get to go house and put this down,” Olaguez informed officers. “We go house and breathe it in whereas we sleep. We’d like actual motion. We have to be moved away from this landfill. We have to breathe clear air.”
Abigail DeSesa, who has lived within the space for about 25 years, stated the persistent odors have trapped her indoors. She stated she has stopped gardening in her yard, mountain climbing native canyon trails and even internet hosting her grandchildren.
“We live like we’re in jail. … Our high quality of life is gone. My well being is gone. And I really feel hopeless,” she stated.
