The Brief

The L.A. County Department of Public Health has found high levels of lead in the soil of properties that burned during January’s fires and have now been cleared by the U.S. Army Corps of Engineers.

The county initiated the testing after the Army Corps said it would not do the testing itself, breaking with a longstanding practice of the federal government doing that work. Army Corps officials said removing up to 6 inches of topsoil would be enough to eliminate hazardous chemicals.

But ongoing testing is finding that is not necessarily the case.

The county hired environmental consulting firm Roux Associates Inc. to sample soil at 30 properties — 15 in the Eaton Fire burn zone and 15 in the Palisades — that had been cleared by the Army Corps.

The results were most worrisome in Altadena, where about 27% of the samples had lead levels above California’s residential safety standard. (No amount of lead exposure is considered safe, but state health standards aim to reduce risk of exposure.)

In the Palisades burn scar, fewer than 3% of cleared properties had lead levels above California’s safety standard.

Lead levels were lower on cleared properties as opposed to properties that had not yet been cleared by the Army Corps: 44% of samples taken from unscraped properties in Altadena had elevated lead levels, while 12% of samples taken at unscraped properties in the Palisades had higher levels.

“While the U.S. Army Corps doesn't decrease the risk in the Eaton area down to zero, it does reflect a significant improvement,” Adam Love, the vice president and principal scientist for Roux, said at a virtual community meeting Thursday.

In mid-April, the county released preliminary testing results showing elevated lead levels in soils of properties downwind of the Eaton Fire.

The county did not share data showing how far above health standards the samples were, saying the data had yet to be finalized. California’s state standards for residential properties say lead levels should not exceed 80 parts per million. The federal EPA’s standard is 200 parts per million.

The county will update the latest testing data on a dashboard tracking air, soil and water testing in the burn zones.

USC researchers have been doing their own testing with property owners as well, finding some samples that are more than three times the standards.

Professor Seth John, who is spearheading that effort, said the team is starting to shift its focus to understand levels of contamination between cleared versus uncleared properties. (If you’re concerned about how the fires affected your soil, you can get involved with the project here.)

Why the disparity between Altadena and the Palisades?

The reason for the difference between the lead levels in the Palisades and Eaton burn scars is not clear.

“The honest answer is we don't know,” Love said. “ It could be related to the difference in the housing stock and the fact that the houses in the Eaton area are more likely to have lead-based paint.”

Love said it could also be a result of ongoing debris clearing dislodging ash, causing lead and other toxic metals to once again settle on cleared properties.

Or, Love added, it could be that lead was already there. It’s not uncommon to find elevated lead levels in Southern California soil because of the region’s industrial history and past prevalence of lead in fuel and paint.

“ There's a lot of different things that could explain why, but we can't just from the data that we collected,” Love said.

That’s why he and county officials said soil testing should be a part of every rebuild plan, and property owners should target that testing to areas that will be exposed and used, such as playgrounds, outdoor eating areas, gardens or walkways.

But fire survivors worry that could lead to additional debris removal needs and even more costs as they try to rebuild.

Testing downwind and blood tests

The county is also launching a large-scale free soil testing effort on May 19.

“This is targeted specifically to homes downwind of the Eaton Fire, where we saw the most significant findings from the soil sampling,” said Dr. Nichole Quick of the county’s Public Health Department.

Quick said about 26,000 eligible homes will receive a postcard invitation to participate.

The program is expected to run through December.

Residents can also get their soil tested free through USC, which is researching how the fires may have affected soil.

Meanwhile, Quick urged residents, especially those with young children, to take advantage of free blood tests. She said you can ask your doctor for a lead blood test, which is covered by most insurance plans, including Medi-Cal. You can also call (800) LA-4-LEAD (524-5323) to schedule a free test through Quest Labs.

You can also go to one of the upcoming county blood test clinics for a free test:

• May 17, 10 a.m. to 4 p.m., 23519 W. Civic Center Way, Malibu.
• May 24, 11 a.m. to 3 p.m., La Pintoresca Park, 45 E. Washington Blvd., Pasadena

Local, state and federal law enforcement agencies have reported using thousands of crowd control munitions against protesters in L.A. since June 2025, when federal immigration sweeps began escalating tensions in the region.

Many people who were never accused of breaking the law nonetheless have been struck by what are known as “less-lethal” crowd control weapons, including rubber bullets, tear gas and flash bang grenades.

Legal experts and witnesses told LAist some of these instances violated California’s protest laws.

While a federal judge banned the LAPD from using 40mm projectiles at protests last month, the department still uses other crowd control weapons. According to Scott Reynhout, who researches these weapons for Physicians for Human Rights, a nonpartisan nonprofit, some of these weapons can be just as dangerous as the banned projectiles — if not more so.

LAist spoke with Reynhout to better understand what they do and how people protesting lawfully can protect themselves.

Reynhout said it's very important that people pay attention if law enforcement declares an unlawful assembly, which they are required to do before using crowd control weapons in most cases.

“ If the police have declared an illegal assembly, it would behoove you to take steps to isolate yourself from that particular situation,” Reynhout said. “If that is not possible for you, for whatever reason — say, you live in the particular area where you are — then you could consider [protecting] yourself from chemical irritants or potentially from impact projectiles.”

Some of the most dangerous crowd control weapons used in L.A.

Physicians for Human Rights’ international study, Lethal in Disguise, found weapons that fire multiple projectiles at once were “far and away the most dangerous” type of crowd control weapons.

 "82% of all the recorded injuries in the medical literature that came from impact projectiles were from ... multiple projectile impact projectiles,” Reynhout told LAist. “And 96% of all the ocular injuries from impact projectiles were from these multiple projectile impact projectiles."

He said the LAPD is the only police department in the U.S. he is aware of that uses this type of weapon. The department uses a 37mm less-lethal launcher (LLM) that shoots five rubber bullets with each shell.

According to reports required by Assembly Bill 48, the department used more than 600 of these shells — that’s over 3,000 projectiles — against anti-ICE protesters last June. They have continued to report using the 37mm launcher, most recently to disperse crowds after the Dodgers World Series win on Nov. 2, according to AB 48 reports.

The 37mm launcher is inherently risky, Reynhout said. Even though the 37mm rubber bullets are smaller than the 40mm projectiles the LAPD was banned from using at protests, they are more likely to hit sensitive areas like the face and neck.

The use of multiple projectiles causes the 37mm projectiles to scatter in a cone shape once they leave the launcher, making them much more difficult to control than a single projectile. He said LAPD’s policy of “skip firing,” which means officers are instructed to aim 5 to 10 feet in front of the person they are shooting at, also adds randomness.

“ The real risk behind these multi-shot impact projectiles,” he said, “is that you just really don't have any control over where these bullets go in the end.”

Reynhout said people standing beside or behind the intended target could very easily get hit, which he believes was likely the case when Australian reporter Lauren Tomasi was struck in the leg by a rubber bullet in June.

[Note: LAist correspondent Adolfo Guzman-Lopez was struck in the throat by a projectile at a 2020 protest. Long Beach police later said they believed that injury was caused by a ricochet of a foam round.]

LAist reached out to LAPD for comment on their use of the 37mm launcher, but the department did not respond.

Another type of crowd control weapon found to be especially dangerous is the use of beanbag rounds, usually fired from a 12-gauge shotgun. These rounds fire small lead pellets sealed in a fabric bag.

Reynhout said the use of these rounds can be “horrific” and leave people with life-threatening injuries.

According to LAPD policy, beanbag rounds are not allowed to be used for crowd control, but other agencies have used them. The California Highway Patrol reported using beanbag rounds against anti-ICE protesters last June.

If you find yourself in a situation where projectiles are being deployed, Reynhout advises focusing on protecting your face and eyes. That’s where the most serious injuries occur.

Reynhout said ballistic eyewear that meets military standards (MIL-PRF-32432) could offer protection against some of the most severe injuries.

He said the 40mm or 37mm projectiles can be similar to getting hit by a golf ball by someone swinging just 6 feet away, and while things like bike helmets, paintball masks, hockey masks or even soft body armor might help to some degree, they aren’t designed to protect someone from that kind of impact.

What you may most likely be affected by: Chemical agents

Chemical agents like tear gas and pepper spray are crowd control weapons that saturate an area and affect everyone in it, Reynhout told LAist, and that includes people who may not even be part of a demonstration.

He said you should be especially aware of these weapons being used near you if you have asthma or any airway or respiratory system issues because they can provoke severe reactions in some cases.

In their report, Reynhout and other researchers found that children and older people are also at risk of severe reactions, which could be life-threatening.

There is gear on the market to mitigate those risks, including sealed safety goggles and respirators (N-, P- or R-100). If you find yourself exposed to a chemical irritant like tear gas or pepper spray, Reynhout said there is nothing shown to be more effective than flushing the area for 10 to 15 minutes with saline solution.

The saline solution should ideally be sterile and at body temperature, he told LAist, but plain water also works if that is what you have available. The important thing is that you continue to flush the area and dilute the chemicals.

For skin or clothing, Reynhout said dilution with water is still the key, but you can use some Dawn dish soap to help wash away pepper spray.

Other dangers

California law enforcement officers have also used flash bang grenades in response to protests since June. The L.A. County Sheriff’s Department and California Highway Patrol together used more than 300 aerial flash bang grenades on June 8, according to AB 48 reports. Those are crowd control munitions shot out of 40mm launchers that explode mid-air and create 170 dB of sound and 5 million candelas of light.

LAist asked the LAPD about their policy on using flash bang grenades for crowd control, but the department did not respond. The LAPD has not listed any uses of flash bang grenades in their AB 48 reports dating back to April 2024.

Aside from these, there are a number of other crowd control weapons and devices that are used by law enforcement agencies in the L.A. area: grenades that explode to release small rubber balls, pepper balls, batons or — unique to the LAPD — officers on horseback using wooden practice swords called “bokken.”

Reynhout said deciding how much protection you might choose to take with you to a protest is very personal. Some bulkier items might restrict your movement, cause you to overheat or impede your ability to maintain situational awareness, so it is important to consider what risks you may face and use your best judgement.

Sometimes, he said, that best judgment might be to walk away from the situation.

L.A. Mayor Karen Bass laid out her vision for Los Angeles at her first of two "State of the City" addresses Monday afternoon at Exposition Park.

The speech, which comes as her race for re-election ramps up, was framed as a celebration of the coming World Cup.

"Let's show the nation and the world we are the greatest city on earth," Bass told the crowd outside the L.A. Memorial Coliseum.

But the mayor moved quickly from announcing that there would be more than 100 free watch parties for the tournament into a retrospective of L.A.'s terrible 2025 — from the January fires to the immigration agents that descended on the city in June and haven't left.

"Raids continue every day in Los Angeles and with them have come the devastating losses of life," she said, naming Renee Good, Alex Pretti and Keith Porter Jr., who was shot by an off-duty ICE agent in Los Angeles on New Year's Eve. " This senseless death, lawlessness and violence must end and so must the presence of ICE in Los Angeles."

Bass described local leaders as the last line of defense against the actions of the federal government.

L.A.’s fire recovery

She also discussed the ongoing recovery of Pacific Palisades, where she has faced substantial criticism for the city's response to the fire and first year of rebuilding, which some residents say has been too slow.

" We've brought in new leadership to overhaul fire preparedness and emergency response," Bass said, referencing her decision to remove former fire chief Kristin Crowley. "And yes, we're fighting the next battle: holding financial institutions and the insurance industry from abandoning Los Angeles because recovery should never feel harder than the disaster itself."

Bass said 400 homes lost to the fire are currently under construction, and that she would travel to Sacramento next week with Councilmember Traci Park and Pacific Palisades residents to push for more state funding for recovery. The Palisades Fire destroyed nearly 7,000 homes and killed 12 people.

The mayor's response to the Palisades Fire is a key issue in her race for re-election. Two of Bass's challengers, former LAUSD Superintendent Austin Beutner and influencer Spencer Pratt, had their homes damaged or destroyed in the disaster.

Housing and homelessness

Bass then laid out her efforts around housing and homelessness, pointing to an affordability crisis that makes staying in stable housing, or buying a first home, out of reach for many Angelenos.

"The greatest test of L.A. is whether people can actually afford to live here year across Los Angeles," the mayor said in her address. "Too many neighbors are packing multiple families into one apartment are working two and three jobs just to stay housed."

Bass lauded her first executive directive ordering city officials to fast-track the construction of developments that have entirely affordable housing units, which she said had "accelerated  more than 30,000 housing units across the city." She also celebrated the city's move to significantly lower rent hikes, in the first reform to rent control in 40 years.

Bass then turned to homelessness, doubling down on her commitment to her signature "Inside Safe" program, which aims to move people off the streets and into interim housing. She said that the city had cleared nearly 120 encampments.

Bass focused on the fight to end homelessness for veterans in Los Angeles — a focus she said was interrupted by the 2025 fires. She said the city had issued 600 housing vouchers for veterans since last year.

She ended the speech where she started — talking about the city's role as host of the World Cup and 2028 Olympic Games.

" We will continue to focus on the fundamentals, the things that shape how a city feels to the people who live here and the millions who will visit," she said.
