The Brief

Not long after the Palisades Fire broke out Jan. 7, firefighting aircraft began drawing bright red lines with fire retardant across the Santa Monica Mountains, in an effort to slow and contain the flames.

By the time the fire was out about three weeks later, the MD-87s, S-2Ts and mammoth DC-10s had performed more than 280 drops across 20 square miles, according to data from Cal Fire obtained via public records requests.

LAist partnered with researchers at USC to test samples of the fire retardant gathered from fire zones in the weeks after the Palisades, Eaton and Franklin fires where it remained on the ground.

Those tests found toxic heavy metals including lead, arsenic, cadmium and chromium, which can accumulate in the environment and pose risks to humans and wildlife, according to federal and state environmental agencies.

Fire authorities say retardant is a critical component of the firefighting arsenal.

A product called MVP-FX, a variant of Perimeter Solutions' Phos-Chek, was the primary aerial retardant dropped on the Eaton and Palisades fires, according to the company.

The presence of heavy metals in MVP-Fx has not been previously reported.

LAist shared the USC lab results with Perimeter Solutions. Jeff Emery, Perimeter’s president of global fire safety, said the company’s products, including Phos-Chek MVP-Fx, have passed extensive testing. He added that the amount of heavy metals found by LAist was far below limits set by the Environmental Protection Agency and “any concerning levels for human health and safety.”

The presence of heavy metals isn’t noted in safety documents publicly shared by Perimeter Solutions.

Aircraft often drop more retardant than water each year on fires in California. From 2006 to 2024, more than 194 million gallons of various types of fire retardant were dropped by aircraft, according to data from Cal Fire.

“We don’t check into every single thing that’s in there,” said Chris Jurasek, deputy chief of tactical operations at Cal Fire.

He said his agency relies on the U.S. Forest Service to test and verify the safety of the retardants it uses. The use of fire retardants is a “critical” component of the firefighting arsenal, according to both Cal Fire and the U.S. Forest Service.

Why we had to run our own tests

Late last year, LAist requested samples of MVP-Fx from Cal Fire, the U.S. Forest Service and Perimeter Solutions, which manufactures the product, for the purpose of running an independent analysis for heavy metals. All declined.

“It’s not in our interest to share product with public or private agencies,” Jurasek said at the time. “You are not the first person to ask for us to give them fire retardant. It happens. It’s not something we do.”

So over the next few months we gathered our own samples from the field.

After the Franklin, Eaton and Palisades fires were under control, I hiked to remote sites and collected vegetation, trash and dirt that had been caked with fire retardant. The samples were placed into baggies and taken to the Environmental Chemistry Laboratory at USC, where the fire retardant was tested for heavy metals.

Marella Schammel, a Ph.D. student, scraped dried red flakes into tubes filled with a diluted mixture of nitric acid and ran them through an inductively coupled plasma mass spectrometer.

Arsenic, cadmium, chromium, copper, manganese, nickel, lead, antimony, thallium, vanadium and zinc were all found in the samples.

Emery told LAist that any trace heavy metals found in testing were “naturally occurring.”

Phos-Chek MVP-Fx is primarily made of ammonium phosphates, which are derived from phosphate. That rock, when mined, can contain trace amounts of heavy metals.

“There are no heavy metals added to any of our formulations,” Emery said.

Cal Fire, the U.S. Forest Service and Perimeter Solutions all dismissed the results of the testing — saying that the samples couldn’t be relied on because they were gathered in the field. That the potential for contamination by ash from burning structures and brush after the retardant was dropped from planes was too great.

Eventually, LAist obtained unused, unmixed MVP-Fx and verified the source and authenticity of the material.

Like the materials collected in fire zones, this unused sample was sent to the USC lab.

Schammel processed the MVP-Fx and found the same heavy metals present as the field samples we gathered.

There were some differences. However, it’s unclear if those differences are due to contamination on the ground or if there’s a variance in the amount of heavy metals present in different batches of the product.

“I’m not too surprised,” said Daniel McCurry, professor of civil and environmental engineering, who oversaw the testing process. Last year he and Schammel analyzed another Phos-Chek variant — LC95 — and found heavy metals as well.

LC95 is one of several USDA approved retardants in use today and one of the variants manufactured by Perimeter Solutions. Cal Fire doesn't use the LC95 variant.

Those results — from tests sparked in part by questions I’d asked McCurry in 2019 about whether we should be concerned about what was in fire retardants — made me want to know more about what is in the fire retardants in use now.

In an effort to compare USC’s test results to the official safety testing required by the federal government, LAist reached out to both Perimeter Solutions and the U.S. Forest Service, an agency within the USDA, for detailed test results for MVP-Fx. Neither would provide them.

In a statement, the U.S. Forest Service said that retardants that qualify for use have to show “nondetectable or trace levels” of certain heavy metals. However, the test results are proprietary information protected by nondisclosure agreements.

'Let people know what they're dealing with'

LAist’s review of publicly available documentation related to MVP-Fx, including its safety data sheet — which is required to warn those who may come in contact with the product of potential risks — found no reference to the presence of heavy metals.

After reviewing LAist’s results and the company’s safety data sheet, Claudia Polsky, director of the Environmental Law Clinic at UC Berkeley School of Law, said the company is likely in violation of multiple California laws and regulations including Cal OSHA standards, unfair competition law and Proposition 65.

“The Cal OSHA hazard communication standards require that a safety data sheet identify every hazardous ingredient in the product,” Polsky said. “Companies often resist disclosure requirements.

“To me this situation is disturbing if unsurprising.”

When asked about the safety data sheet, Emery said that the company works to “ensure compliance with all applicable regulatory requirements concerning our product.”

Some who regularly work with Phos-Chek said that LAist’s findings were a surprise to them.

“ The heavy metal thing, I can tell you, was news to me,” said Joel Lane, air tactical group supervisor with the Orange County Fire Authority. He’s worked in the industry for decades and has come in contact with different variants of Phos-Chek, both during preparation and when it’s been dropped on him by aircraft.

Lane said that he’s never been told or read in official documentation that heavy metals could potentially be present in retardant, which he finds upsetting.

He said the lack of transparency is concerning, but that it wouldn’t be the first time.

Lane feels firefighters were left in the dark about the risk of PFAS — long-lasting chemicals used in firefighting foam and in the heavy gear firefighters wear — that have been tied to elevated rates of cancer, according to the Environmental Protection Agency. Lane himself recently survived prostate cancer.

“ Be transparent, be open. Let people know what they're dealing with,” Lane said. It’s only then that they can make informed decisions about risks for themselves, he added.

LAist asked the U.S. Forest Service about potential risks to firefighters, to which they responded that “risk assessments of firefighter exposure to retardants do not indicate an increased risk for health effects,” pointing to a health assessment conducted by the agency, which includes MVP-Fx.

Although the assessment says risks are expected to be generally negligible, it doesn't explicitly mention heavy metal exposure. The U.S. Forest Service didn’t respond to whether heavy metal contamination was taken into consideration for the assessment.

What’s the risk to you?

Heavy metals can pose a serious health risk and have been tied to increased rates of cancer, as well as reproductive and developmental issues in humans.

That said, multiple health experts told LAist that the risk to members of the public exposed to the retardant when doing activities like hiking, is likely low, given the concentration of contaminants present in our samples.

“It should not be a reason for panic, but maybe it's a reason for caution,” said Dr. Ana Navas-Acien, professor and chair of Environmental Health Sciences at the Mailman School of Public Health at Columbia University, who reviewed the results.

Sanjay Mohanty, associate professor of civil and environmental engineering at UCLA, agreed, saying that the risk for people with limited exposure, such as homeowners or hikers, is “very low.”

If you or your pets are exposed, it’s a good idea to wash it off.

Environmental effects

Retardant is a particular concern if it gets into aquatic ecosystems.

Fire retardants can be particularly dangerous to aquatic ecosystems, according to a U.S. Forest Service environmental impact study published in 2011.

Once retardant enters waterways it can lead to elevated ammonia levels, which in turn can be toxic to salmon and trout. And there’s a possibility that an influx of nutrients from retardant can boost algal growth and create dead zones, killing off organisms there.

Because of these risks, the U.S. Forest Service prohibits the dropping of retardant within 300 feet of waterways, though it does happen. There have been more than 240 intrusions since 2012, according to another U.S. Forest Service environmental impact study from 2023.

However, even if the retardant doesn’t get dropped directly on waterways, it can get washed into them by rain. Heavy metals can settle in streams and ponds and potentially have devastating impacts on organisms there.

William Clements, a professor in the Department of Fish and Wildlife Conservation at Colorado State University, homed in on the cadmium LAist found in the MVP-Fx.

“ If even a small fraction of that ends up in that stream, that is cause for concern,” he said.

The heavy metal can get taken up by sponge-like algae, which is then eaten by aquatic insects such as mayflies and stoneflies, which can die when exposed to the cadmium. Exposure to the heavy metal can also inhibit their reproduction, growth and ability to emerge from streams, compromising a source of food for fish and birds, according to Clements.

“ The levels of metals will increase and will be bioconcentrated over time. Not now, but in a year, two years, maybe five years from now,” said Dmitri Deheyn, a marine toxicologist at the  Scripps Institution of Oceanography.

“ People need to make the association that the impact is a lingering impact that will be diffused and diluted over time and space.”

In an effort to figure out how much heavy metal was spread throughout the San Gabriel and Santa Monica mountains during the Eaton and Palisades fires, LAist requested information on the total number of gallons of retardant dropped, from both the U.S. Forest Service and Cal Fire, via records requests. None were fulfilled.

With tensions already high in Minnesota after an Immigration and Customs Enforcement officer killed Renee Macklin Good, the Trump administration is ramping up the pressure on cities and states to cooperate with its immigration crackdown.

The administration had already surged federal agents — sometimes accompanied by military troops — to Los Angeles, Portland, Chicago, Charlotte, Memphis, Washington D.C. and New Orleans.

Now the White House is threatening to cut funding for sanctuary cities. Here's a brief explanation of how local governments interact with federal immigration enforcement, and what the White House can and can't require from them.

A fight over federal money 

President Trump threatened this week to cut "significant" federal funding to sanctuary cities. He hasn't said exactly what money his administration wants to cut, though he gave a deadline of Feb. 1.

Nor has Trump said exactly which cities or states will be targeted, though the Department of Justice did publish a list of more than 30 cities, states and counties in August. (That list includes the state of Minnesota, though not Minneapolis or St. Paul or their respective counties).

In remarks on Tuesday at the Detroit Economic Club, Trump seemed to be focused on places that limit their cooperation with ICE.

"They do everything possible to protect criminals at the expense of American citizens. And it breeds fraud and crime and all of the other problems that come," Trump said. "So we're not making any payment to anybody that supports sanctuary cities."

This is not the first time President Trump has made a threat like this. During his first term, the president tried to withhold some federal funding from sanctuary cities. More recently, Trump signed an executive order nearly a year ago directing the Departments of Justice and Homeland Security to make a list of sanctuary cities and withhold money from them.

But courts have sided against the administration in nearly every case, saying that the federal government cannot use funding to coerce state and local governments into changing their policies on immigration.

"Here we are again," U.S. District Judge William Orrick in San Francisco wrote in April. Orrick granted (and later extended) a preliminary injunction blocking the Trump administration from withholding federal funds from 16 jurisdictions, including San Francisco, Portland, Seattle, Minneapolis, St. Paul and New Haven.

"The threat to withhold funding causes them irreparable injury in the form of budgetary uncertainty, deprivation of constitutional rights, and undermining trust between the Cities and Counties and the communities they serve," Orrick said.

No precise legal definition of 'sanctuary'

There's no exact legal definition of "sanctuary city." But broadly speaking, the term refers to any city, state or county that limits its cooperation with federal immigration authorities.

The legal questions here are nuanced. Local law enforcement cannot block federal agents from doing their work but courts have said that state and city officers can withhold some cooperation.

The legal arguments are rooted in the U.S. Constitution and the division of powers between the federal government, which is in charge of immigration enforcement, and state and local governments, which run their own police and sheriffs' departments.

Courts have backed states that don't want to share data on residents in their records, including information about driver's licenses. And in many places, state and local law enforcement will not honor what's known as a "detainer request" from ICE, which essentially asks police to hold someone in detention until immigration authorities can take custody.

Local officials push back 

Virtually all the cities and states the administration has focused on so far are led by Democrats, who don't seem to be backing down after Trump's threat to cut federal money.

"This is just a threat to intimidate states like New York into bowing into submission. And that is something we'll never do," New York Governor Kathy Hochul said earlier this week. "You touch any more money from the state of New York, we'll see you in court."

State and city leaders argue there is a fundamental public safety rationale for their sanctuary policies. They say that working with ICE would undermine trust and cooperation between local law enforcement and immigrant communities as they seek to prevent crime.

There's clearly a political aspect to this as well. In many sanctuary cities, voters are asking Democratic leaders not to give in to the White House and its immigration agenda, so local leaders may have a strong incentive to dig in their heels.

Why local cooperation matters 

In the past, ICE has found that it's faster and safer to arrest people who are already being held in local jails. And that's one reason ICE was able to make so many arrests during the administration of President Obama, for example, before sanctuary policies were as widespread as they are now.

The White House says a lack of local cooperation is hindering its efforts to build "the largest deportation operation in the history of our country," a pledge Trump made frequently during his reelection campaign.

"Minnesota's 'leaders' have chosen defiance over partnership," the White House said in a statement on Friday.

But Democrats say the administration is deliberately creating confrontations in cities and states that are led by political opponents, provoking chaotic scenes on purpose for reasons that go beyond simply enforcing immigration law.

On a recent Saturday, a group of teenage musicians took to a stage inside an unlikely place: an unassuming unit in a business park at the bottom of Lincoln Avenue in Pasadena.

This space has a stage sitting on its concrete floor with the words "Backyard Party" playfully scrawled across the bottom.

The members of a band called The Wendolls sound checked with Matt Chait at the mixing board.

Backyard Party, one of the area’s newest all-ages venues, is the brainchild of Chait and fellow organizer Sandra Denver.

“The fires crushed garages where kids would have been playing. It burnt backyards where they would have been playing. It burnt down the schools where they would have been playing. So this is the communal backyard party. That’s specifically what we built and why we built it,” Chait said just outside the makeshift venue. The only thing that sets it apart from the nondescript units around it is a handwritten sign that says ‘No Ins and Outs.’

Chait, who was evacuated from his residence during the Eaton Fire, teamed up with Denver to manage the volunteer-run Backyard Party a few months ago. Her daughter sung lead vocals in a band called Sly, one of four bands on the lineup.

“We wanted to provide a space for all of the teen bands all around to come and play and help them create a kind of scene,” Denver said.

It’s the type of spot Denver said she wishes she had growing up in Phoenix, Arizona.

And she’s just one of several supportive parents here who are helping load in amps and guitars and bass drums.

Sixteen-year-old Jett Bizon is the drummer for Saints of Sinners, one of the bands on the bill. He said there’s another reason there are so many parents in the crowd.

“Well, nobody drives. Everybody needs a ride,” Bizon said with a chuckle.

With his long dark hair, Bizon explained that he’s already played some legendary local venues like The Whiskey a Go Go. But he said it feels like Backyard Party is becoming a much needed space for younger musicians in the area.

“We need to let out some type of energy and everybody’s putting it into music,” Bizon said. “I think it’s a great thing. Finally a scene again, it’s fun.”

As Bizon and his bandmates played their set of hard rock songs, the only people on their phones in the crowd were parents filming.

Some of the young folks taking the stage were affected by the Eaton Fire in one way or another. Some of them were evacuated. Others lost homes or saw their friends displaced.

Payton Owen was part of the crew running the door, taking tickets and dolling out snacks. She too is a musician and writes reviews of some of the concerts here.

“I think it’s amazing. I think it’s really like a point of community,” she said from behind a glass case filled with bags of popcorn and candy. “It’s a really nice opportunity for kids to really have somewhere where they can go.”

Teenager Elise Lamond agreed. She’d been following Chait around all night, learning how to set levels for the musicians, run the house lights and more.

“Most people at this age don’t have those kinds of opportunities,” she said, adding that, as a musician herself, she appreciated having free access to the venue’s music equipment, too.

Chait, who had a hand in running the now closed AAA Electra 99 venue in Anaheim and has been a musician since he was 12, said Pasadena and Altadena have a noteworthy music pedigree.

“I mean, Van Halen started in quite literal ‘backyard parties’ over on Allen. I think it lives here,” he said.

And Chait said he’s blown away by the new talent that’s come to this stage. For his part, he thinks it’s the start of a new scene that will balloon beyond Altadena and Pasadena.

“The fact that these kids who are now, let's say, 15-20 all lived through COVID and were very separated from each other. And now, in this particular neighborhood, are also separated again because of the fires. And they have supportive parents and now they have the physical place to be... All of the pieces of the puzzle are here,” Chait said.

For now, Chait said this is a labor of love. The space here is provided by Altadena Musicians, a non-profit that’s working to get instruments back in the hands of people who lost their gear in the fires. And as for ticket sales?

“It is the best part of running the venue: the end of the night, when we hand cash to these kids for playing,” Chait said.

Tonight’s bounty from a full-house? $320.

“There’s a couple of these kids, if they play one or two more times, we’re going to have to give them 1099s,” he said.

On Friday, Southern California Edison filed lawsuits against Los Angeles County and several other agencies over their alleged roles in the Eaton Fire.

Two lawsuits were filed.

In one suit, the utility company alleges Southern California Gas delayed shutting off gas in the burn area for several days after the fire, making the blaze worse.

“SoCalGas’ design and actions caused gas leaks, gas fires, reignition of fires, gas explosions and secondary ignitions during the critical early stages of the Eaton Fire,” according to the suit.

The claim goes on to say this contributed to the spread of the fire and made firefighting and evacuation efforts more difficult.

In the second suit, the utility company alleges the Eaton Fire was made worse by the local government response, “including due to the failures of LASD, LACoFD, OEM and GENASYS in issuing timely evacuation alerts and notifications,” the claim reads.

The same filing says L.A. County was to blame for vegetation and overgrown brush in the Eaton Canyon area that fueled the blaze.

It also named the city of Pasadena and its utility system, Pasadena Water and Power, the city of Sierra Madre, Kinneloa Irrigation District, Rubio Cañon Land & Water Association, Las Flores Water Company and Lincoln Avenue Water Company as parties responsible for water systems running dry in Altadena as the fire broke out.

Edison says hydrants running dry compounded the extent of the disaster.

Those claims will be heard in the L.A. County Superior Court, which is also handling L.A. County’s lawsuit against SoCal Edison.

Edison itself is the subject of hundreds of lawsuits from survivors of the Eaton Fire, which could cost the company billions of dollars in settlements.

Edison has said its equipment likely sparked the Eaton Fire and filed these suits, in part, because it believes these various entities should share some of the blame for the disaster, which resulted in the destruction of thousands of buildings and the deaths of 19 people.

A compensation program Edison established for fire survivors who forgo suing the company has made settlement offers to more than 80 of those who applied.

A new organization is taking over production of the MLK Day Parade, almost 40 years after the first parade was held in South L.A. to commemorate the civil rights leader.

Bakewell Media, publisher of the Los Angeles Sentinel newspaper (a partner of The LA Local), was granted the permit in September to organize the parade for the first time by the Los Angeles Board of Police Commissioners. Formerly called the Kingdom Day Parade, the parade has been rebranded as the Los Angeles Official Martin Luther King Day Parade. The parade was previously produced and organized by Adrian Dove and the L.A. chapter of the Congress of Racial Equality California (CORE-CA).

With less than a week before the parade kicks off, LA Local reporter LaMonica Peters sat down with Danny Bakewell Jr., president and executive editor of the LA Sentinel, to discuss the details and what attendees should expect.

This Jan. 12 interview has been edited for brevity and clarity.

Why did you decide to produce the MLK Day Parade this year?

Bakewell: It all started because Adrian Dove, who was the previous promoter, had announced that he was retiring. When he announced he was retiring, LAPD, city council offices and other people said, “Hey, we still want to do the MLK Day parade. Would you guys be interested? You have the infrastructure to put it together.” And we said yes.

What’s different about this year’s production?

We’re going to start the parade with a singer performing “Lift Every Voice.” We’re going to play the message from Bernice King at the start of the show. Obviously, we have Cedric the Entertainer as our grand marshal to add the entertainment value, but the community has always been and will continue to be a major part of this parade.

Is ABC 7 covering the parade this year? 

It’s still going to be televised by ABC. We’re working diligently on how the show is going to be, but ABC has been a great partner.

What was the preparation for this parade?

Thanks to our corporate sponsors, we have a number of bands. The truth is, particularly in LAUSD at this time, and other school districts, they don’t have the funding to just get a bus and get here. I can’t say enough about Airbnb to Bank of America, all of our corporate sponsors, who are supporting all of the youth organizations.

Were there any unexpected challenges while preparing for this parade? 

This [The LA Sentinel office on Crenshaw Blvd.] is usually our command center during The Taste of Soul. It dawned on me last week that we’re going to be a mile away [from the parade route]. So, we made the decision to bring in a trailer to be our office at the corner of King and Crenshaw boulevards.

Any special guests this year besides the grand marshal?

I’m working on a surprise guest to be the singer for the national anthem. No matter what, we will give tribute to the Black national anthem “Lift Every Voice” as loud as we can next Monday.

What’s the long-term vision for this parade, if Bakewell Media continues to produce it?

We see the MLK Day Parade, and we want the world to see and expect to see this parade, the same way they see the Macy’s Parade, the Hollywood Parade or the Rose Parade. BET has come in this year as a partner. So there’s an opportunity to possibly do a national broadcast on BET. Not that we would lose our local television, but we see this as a major parade in this community and in the national African American community, celebrating the great work of Dr. Martin Luther King Jr. So, we are very excited.
