The Brief

Wearing gloves and a KN95 mask, Emmanuel Carrera Ruedas hunkered down near a storm drain, just steps away from the smoldering Lineage warehouse fire, as he filmed himself pointing to what he described as insulation and foam flowing into the drain.

“The thing about this water is that it all gets dumped straight into the L.A. River,” Carrera Ruedas, of Cudahy, told his Instagram followers in a June 22 reel.

In the past two weeks, Carrera Ruedas has spent evenings gathering water samples outside Lineage and from the L.A. River as he and other community scientists are partnering with experts from UCLA and Columbia University to learn what’s in the runoff. Samples will soon be sent to a lab in New York.

“For far too long, the river has just been a drainage, a dumping site for companies,” said Carrera Ruedas, 27, who often encounters toads, birds and fish inhabiting its ecosystem.

“There is life in there,” he told Boyle Heights Beat. “We’re all in proximity to the river, and that’s kind of the vein that runs through the city that really connects us all.”

Community-led testing

Since the Lineage fire ignited June 17 in Boyle Heights, residents, environmental advocates and researchers have taken it upon themselves to find out what’s in the air and water. They’ve launched their own sampling efforts, seeking answers about what people have been breathing and contaminants that may have entered the L.A. River.

The community-led testing comes as residents have reported eye irritation, nausea and headaches while questioning whether the government has done enough to capture the fire’s environmental and public health impacts.

Those concerns are especially alarming in Boyle Heights, East L.A. and neighboring Southeast L.A. communities, where neighbors have long faced disproportionate pollution burdens.

An estimated 31,700 workers, about 81% of whom are Latino, live in the county and city zones where a smoke advisory was issued, according to new data from the UCLA Latino Policy & Politics Institute. They work in health care, manufacturing and food service industries. About half of the workers earn $3,333 or less a month, below L.A. County’s “very low income” threshold.

The area also experiences diesel pollution levels three times the county average, as well as higher rates of asthma and cardiovascular disease-related emergency department visits, according to UCLA. Nearly 10,000 households in the area lack air conditioning.

“This is not only an air quality emergency but also a worker and environmental justice issue,” UCLA said.

Behind the push for environmental justice

For years, East Yard Communities for Environmental Justice has shed light on how Latinos on the Eastside often bear the brunt of the region’s pollution and climate disasters, such as the East L.A. oil spill in late May that dumped nearly 25,000 gallons of crude oil onto streets and into the L.A. River. For the organization, “We are just trying to breathe” is a common phrase.

“Something I’ve told many people over a long period of time is, ‘We’re not polar bears. We’re not whales.’ Nobody is coming to save us. We have to step up and defend ourselves,” said mark! Lopez with East Yard Communities for Environmental Justice.

East Yard members opted to take air samples themselves, dissatisfied with the South Coast Air Quality Management District’s assessment of the fire’s air-quality impacts. They placed sorbent tubes, which Lopez described as passive air monitors, outside nearby homes for about seven days. Soon, they’ll send the findings to a Columbia University lab with the help of UC Irvine.

What officials have done so far

South Coast AQMD said it conducted “mobile monitoring” during the first two days of the fire that found “significantly elevated concentrations” of particulate matter. The agency then deployed particulate matter monitors at Eastman Avenue Elementary and Robert Louis Stevenson Middle School that provide “near-real time exposure information.” AQMD noted that the L.A. Fire Department and the U.S. Environmental Protection Agency conducted their own monitoring, while third-party contractor Onterris has continued monitoring during the cleanup phase.

AQMD also observed smoke impacts throughout the region, issuing a particle pollution advisory in English and Spanish that remained in effect through June 24.

What's next and lingering questions

Meanwhile, Lopez said more sampling is necessary, and he questioned the effectiveness of efforts by Lineage, AQMD and LAFD. He and other advocates criticized public statements from officials, including Mayor Karen Bass’ assurances that “the air is not dangerous,” even as residents were reporting feeling sick. He also took aim at LAFD Chief Jaime Moore’s statements that ammonia was not toxic to individuals unless they had respiratory issues or came in direct contact with it. East Yard also called for evacuations in the area.

“It feels like at the city and county level they don’t currently have the capacity to really handle this situation,” Lopez added. “I think it really requires state and federal intervention to make sure that the cleanup and restoration isn’t mismanaged.”

Yoshira “Yoshi” Ornelas Van Horne, an exposure scientist and assistant professor with the UCLA Fielding School’s Department of Environmental Health Sciences, said the Lineage fire is exposing how little is done to “respond to public health emergencies and disasters” in communities like Boyle Heights and East L.A., areas “that have so often been referred to as environmental injustice communities.”

Residents and community organizations like East Yard, Ornelas Van Horne said, “are always the ones having to respond.”

“They’re relying on each other. They’re relying on their networks and their organizing power to be able to do that on the ground sampling.”

Ornelas Van Horne reached out to colleagues at Columbia’s Multi-Element Trace Analysis Laboratory in New York after she learned of the sampling taking place and of community concerns about the runoff making its way down to the L.A. River.

Those samples will be analyzed for heavy metals like cadmium, lead and arsenic, she said.

The L.A. County Public Works Department, according to the Los Angeles Times, deployed three containment booms on the L.A. River and continued to monitor the water as it made its way to the ocean.

Carrera Ruedas began collecting water samples on the third day of the fire. He said he took the first sample from the L.A. River, about 100 meters from the spout where it spilled out. The second was taken from outside Lineage. He has amassed dozens of samples since then.

Cudahy sits alongside the lower L.A. River, and after the fire, Carrera Ruedas recalled a “heavy stench that affected people in our community.” The trash he saw in the river was the foam and insulation that came from Lineage, he said.

“It really pissed me off, just to see all this trash go in there and nobody doing anything about it,” said Carrera Ruedas, who also serves as the parks and environmental justice commissioner for Cudahy.

The L.A. River, Carrera Ruedas said, is “part of our ecosystem.”

“This is not just affecting me. This affects everybody else around me. This affects people who love the beach, people who just want our water systems clean,” he said.

A criminal justice watchdog is calling into question whether Latinos in the L.A. County Superior Court get a fair shot at bail.

The new report from the nonprofit La Defensa, which advocates for reform in the legal system, analyzes a sample of pretrial decisions from 2025 which had been documented by community court-watching volunteers.

One of the key findings was that defendants who were perceived to be Latino had an average bail amount of $157,700 — more than 15 times higher than white defendants and nearly three times higher than Black defendants.

Studies show that inability to pay bail can affect defendants’ livelihoods and their ability to defend themselves, according to the Vera Institute of Justice.

“ Most families — no matter what they did, no matter what they sold — cannot actually purchase that person’s freedom to give them the fighting chance to go against the state,” Titilayọ Rasaki, La Defensa’s state policy and legal affairs director.

The L.A. County Superior Court says it’s following the law on bail requirements and that the findings are missing context because observation is limited.

How court-watching works

La Defensa’s Court Watch LA program is a community-led effort to document and hold the courts accountable. They train volunteers to go in and observe cases.

The volunteers take notes on the charges, the judge’s conduct and the person’s criminal history, if it comes up. That then gets analyzed against publicly available case information and state law. Programs like this exist in several other cities around the country.

For the latest report, La Defensa volunteers observed 140 felony and misdemeanor criminal cases, chosen at random, between January to November 2025.

Judicial accountability lead Bryanna Siguenza explained how she decided where to send the volunteers.

“ I choose a department, specifically ones that are pretty busy, have high case loads, and are arraignment and pretrial,” she said.

What watchers saw

Racial disparities in pretrial settings have been researched at local, state and national levels, but La Defensa’s findings are based entirely on human observation, Siguenza said.

The volunteers are trained to listen for important details that come up in proceedings, but they may not always get the full story behind the charges, like a defendant’s criminal history.

L.A. County Superior Court spokesperson Rob Oftring said the report needs more context.

“Many of the report’s findings, for example, do not appear to account for charge severity or criminal history, both of which are legally significant factors in any release decision…” he wrote in a statement.

La Defensa did not include in its report what charges had been filed in the cases observed. However, according to the report, comparable charges still had disproportionate bail outcomes that “couldn’t be explained by charge severity alone.”

The severity of charges legally informs bail decisions. The Superior Court is required to have standard bail amounts based on the crime, which judges have discretion to adjust.

State law also requires judges to weigh issues like public safety in bail decisions, as well as the defendant’s ability to post bail. According to the volunteers’ observations, the judges considered the latter in just a quarter of cases when setting bail.

Oftring said the court has taken steps to reduce money bail’s usage as allowed by law.

“Bail at arraignment is set only after both the defense and prosecution have been heard and the judge has weighed the specific facts of the case,” his statement read.

The limits of the findings

Oftring said the court values the role organizations like Court Watch LA play in keeping the justice system accountable, but that the sample size of the researchers used in their report is too small to draw any definitive conclusions.

Roughly 272,000 criminal cases took place during that time period, according to Oftring.

Representatives from La Defensa said they know the report is only a snapshot of the system, and that human observation has its limits.

That’s why in November, they requested 10 years of de-identified data to analyze whether bail outcomes differ across judges, courthouses and demographic groups. Rasaki said they haven’t received it.

“  We would say release the data … by all means, we want to partner. We want to analyze,” she said.

Oftring told LAist they are working on several projects that “provide data-informed scrutiny of how the court operates.”

Southern Californians are in for yet another scorching weekend.

The National Weather Service has issued a heat advisory for much of the region through Monday, with temperatures expected to hit their peak on Sunday.

Highs in the San Fernando Valley, San Gabriel Valley and other inland areas of L.A. County are expected to range from the mid-90s to about 105 degrees. Downtown Los Angeles and much of Orange, Ventura and Santa Barbara counties will get up to the lower 90s. Beaches will also be hot — in the lower 80s.

Moving farther east, things get really toasty. Forecasters have issued a more severe extreme heat warning for parts of the Inland Empire, where temperatures could get up to 108 degrees, and for the Coachella Valley, where they could hit 120.

Humidity will likely also continue to add to the discomfort, but will be concentrated in areas closer to the coast, where it will keep nighttime temperatures relatively warm and make it more difficult to cool down. Inland areas will feel drier.

Those who are most at-risk from the heat are people who work or spend time outside, people without access to air conditioning and those who are either over 65 or young children.

Forecasters are also warning of dangerous rip currents and swells along the coast this weekend.

If you’re headed to the beach to beat the heat, as many Southern Californians likely are, they recommend staying out of the water or, if you do go swimming, stay in front of lifeguards. It’s also a good idea to avoid jetties and tidal rocks.

Wildfire risk

This weekend will also come with a high risk of wildfires.

Forecasters warn that fire danger will be elevated through at least Monday, driven by heat, dry vegetation and low humidity levels away from the coast.

Despite some extra moisture in the air over the last several weeks, there hasn’t been enough to actually produce rain. Without precipitation, and under consistently high temperatures, plants will continue to dry out and become fuel.

“We have humidity, but it's not reaching the saturation point. Therefore, we won't have a cloud. We won't have precipitation,” said Rong Fu, an atmospheric scientist at UCLA who specializes in weather patterns and wildfires.

Fu said a system of high atmospheric pressure sitting over the Western U.S. is pushing warm, dry air across the Sierra Nevada from inland deserts and into Southern California.

That can generate what’s known as downslope wind. Those winds plus the already dry conditions align to create some especially dangerous fire weather.

One spark can easily turn into a large blaze, and humans are the most common cause of wildfires in Southern California, according to the U.S. Forest Service.

People can accidentally start wildfires in a range of ways, including throwing a lit cigarette into dry brush or dragging a chain behind a vehicle, creating sparks. One of the most common human causes is improperly extinguished camp fires.

Lightning can also start wildfires but is unlikely under current weather conditions. Southern California has seen minimal thunderstorms this summer.

The new normal?

Heatwaves in the summer and fall are obviously not new for Southern California, but they are getting worse.

Much of the heat currently blanketing the region is being driven by the high-pressure system, which traps warm air and compresses it against the ground, heating it even further. Forecasters say it’s likely to stay that way through the end of July.

But high-pressure systems like this one usually don’t stick around this long.

“For this pattern to linger almost two weeks — yeah, I would say, from a climatological point of view — that's pretty unusual,” Fu said.

One major driver of the change, Fu said, is climate change: As the climate warms, this kind of “anomalous” high pressure system will become stronger and more frequent.

And one consequence of hotter and longer heatwaves, is extended elevated periods of risky fire weather.

This story first appeared on The LA Local.

Los Angeles will be under a heat wave advisory until Monday evening as temperatures show no signs of letting up over the weekend.

Temperatures will linger in the high 80s and low 90s in downtown and the surrounding neighborhoods, including Koreatown, Pico Union and Westlake.

The National Weather Service projects temperatures will peak on Sunday afternoon. Meteorologist Bryan Lewis with the National Weather Service said residents can expect more humidity than usual. 

While dense, urban centers have more concrete and see more vehicle traffic, downtown and the surrounding areas will not be the hottest locations during this heatwave in the Southland, as the Antelope Valley will be under an extreme heat advisory over the weekend.

During hot weather, the beach is an immediate go-to for folks that want to stay cool, but Lewis warns against this as the surf will be extra choppy.

The Pacific Coast will see large swells “coming up from tropical systems off the coast of Mexico,” Lewis said. “We are issuing a beach hazard statement that’ll be in effect through at least the weekend [which] may be extended.” 

While the weather is expected to cool down on Monday, forecasts show that another heatwave could develop by the end of next week.
