As fires set LA ablaze, some houses are left standing amid ashes thanks to concrete walls, class A wood – and luck

When last week’s fires in Los Angeles set parts of the city ablaze, one viral image was of a lone house in Pacific Palisades that was left standing while all of the homes around it were destroyed.

Architect Greg Chasen said luck was the main factor in the home’s survival, but the brand-new build had some design features that also helped: a vegetation-free zone around the yard fenced off by a solid concrete perimeter wall, a metal roof with a fire-resistant underlayment, class A wood and a front-gabled design without multiple roof lines.

As the known drinking water nerd amongst my friend group, I have been informally fielding questions about whether their water is safe to use near the wildfires in Southern California. Some common questions I’ve heard include: How do I know if I can drink the tap water? Can I shower with it? When will it be safe? Beyond more generally getting the facts right on the water and wildfire issues in California, as this Guardian headline suggests, it’s smart to assume the worst about the safety of drinking water in and throughout the immediate aftermath of devastating disasters like the Los Angeles fires.

Why be concerned about the safety of your drinking water after a major fire?

As colleagues so comprehensively explained in their “Wildfire and Water Supply in California” report, there are a lot of pathways by which a wildfire can make your tap water unsafe (and a lot of great ideas on how to adapt to this growing challenge). In Northern California, the Tubbs Fire’s effects on Santa Rosa in 2017 and the Camp Fire, which burned the entire town of Paradise only a year later, were among the first wildfires known to cause widespread drinking water contamination in cities.

Wildfires in forests and wildfires in urban areas have different consequences. Alarmingly, after the Tubbs and Camp Fires, researchers found evidence of post-fire contamination from volatile organic compounds (VOCs) like benzene, which is carcinogenic, and also from heavy metals, microbes and other contaminants that pose both immediate and long term public health risks. As fossil-fueled fires get worse, tap water contamination concern grows. Drinking water may not be safe for months, depending on the severity of the damage.

To name a few ways water can be contaminated post-fire:

• Incineration of urban infrastructure—houses, buildings, electric wires, etc.—leaches toxic chemicals not only into our air but when hot enough, can melt the underground pipe network that deliver drinking water.
  
• Toxic runoff from the combination of burnt infrastructure, any fire retardant that has been dropped and water to fight the fires, infiltrates into the ground and any stormwater system.
  
• Any disconnection or disruption to an otherwise closed loop treated drinking water distribution system creates risks of contamination.
  
• Distribution network depressurization may also allow for contaminant transport between differently impacted parts of the distribution system.

I live in or near a fire-impacted community, what should I do?

Figure out who your water provider is if you don’t know. Community water systems provide drinking water for most Californians, and there are a few tools to consult to identify your water system:

• The Community Water Center’s Drinking Water Tool, features an address-based search tool available in Spanish or English.
  
• For residents of LA County, the UCLA LA County Water System Governance Map, shows the service areas for more than 200 systems in the county, and is available in Spanish or English.
  
• The state regulatory agency for drinking water maintains a Human Right to Water Portal, which is also address based and includes not only community systems, but also the schools and daycares responsible for complying with safe drinking water standards.  

Then, check your water provider’s website for any advisories like “do not use”, “boil water”, or “‘do not drink”’ notices. (Learn more from the CDC about the difference between them). Depending on the contamination issue, and unless advised by your water provider, it’s unlikely that you can self-treat the water to make it safe by boiling, filtering, adding chlorine or other disinfectants etc.

Check out the LAist Cheat Sheet which compiled thorough FAQ for LA area residents, including how to understand different advisory types, where to get replacement bottled water and your local water provider’s phone number to get your questions answers.

Areas affected by Do-Not-Drink-Water notifications and other water advisories are dynamic. Large water providers like Pasadena Water and Power and LA Department of Water and Power are actively testing and working to get water back to regulatory standards. Smaller systems may have a harder time recovering.

The above concerns and suggested steps are focused on the safety of the tap water being delivered to your house and do not address very real concerns due to on-site contamination from damaged infrastructure on private property. Always review official resources for those impacted by the LA Fires: https://www.ca.gov/LAfires/.

I have a domestic well, what should I do?

If you are not in the service area of a community water system, your house may have a private domestic well. All the fire-related toxic substances infiltrate the soil and reach our groundwater, they contaminate it with dangerous substances that any added chlorine or household point-of-use filters may not remove. That translates to a higher level of pollutants in our tap water, especially when fires occur near a drinking water well.

Domestic well owners are responsible for managing their own water quality, even when impacted by events outside their control. While a brand new law now requires landlords to ensure their rental properties’ wells are tested, there is no state agency that regulates domestic well water quality they way they do for water systems.

Some ideas on how to learn about the safety of your tap water:

• Assess your well if impacted by wildfire, considering using the CDC’s rapid assessment form
  
• Review the SWRCB’s Guide for Well Owners and Well Testing Program Directory, and search by your county to see if which programs are available in your area.
  
• Follow the CDC’s checklist depending on issues experienced from loss of power, to loss of pressure and hire licensed professionals to repair or replace damaged components.
  
• If your house also has a septic tank, check for any signs of damage that could cause issues for indoor plumbing or domestic well contamination.
  
• Review official state resources for those impacted by the LA Fires: https://www.ca.gov/LAfires/

Not impacted by the fires, but want to help? Fire recovery will be a long process, and donations of critical supplies like bottled water will be needed long after the media moves on from this disaster. Find a trusted local organization, like the Pasadena Jobs Center, an organization coordinating volunteers on the ground and recommended by a friend who grow up in Altadena and lost their family home in the Eaton fire. Consider directly supporting mutual aid groups now and in the coming months.

President-elect Trump’s threats to swiftly implement a policy of mass deportation for immigrants in the United States without legal status, as well as end programs that provide lawful temporary protected status for many immigrants, are inhumane. Immigrant rights groups and legal experts have rightly sounded the alarm and are working actively to fight back and resist these actions, which could be announced on Day 1 of the Trump presidency. All of us—whether we or our families, friends and community members are directly impacted or not—have a stake in understanding why these policies are so harmful, morally reprehensible, and have no place in a democracy.

We in the US are part of a country whose history and present-day social and economic realities are deeply intertwined with and built on the experiences of immigrants, enslaved African Americans, and Indigenous peoples. Owning that history—the good and the bad—is a crucial part of what it means to be an American. And it’s the first step in charting a path to a better, fairer future for our country.

The current US system of immigration is clearly broken, and across the political spectrum there is a recognition that reforms are urgently needed. I am not an immigration expert so I will not opine here on the details of those reforms.

What is clear—or should be clear—to all of us is that if we arbitrarily judge some immigrants to be “better” than others, we will inevitably risk reinforcing a system that is based on biased and unequal power and economic structures that are pervasive in the world today. All too often, current legal pathways to immigration privilege a subset of people while shutting out many who work equally hard and are equally deserving.

As my colleague Karen Perry Stillerman points out, in addition to being morally repugnant, mass deportation programs would have a significant negative impact on our nation’s food system, which could not function without the labor of immigrants.

As another example, as extreme weather and climate-related disasters mount across our nation, it is often immigrants who help to do the difficult and dangerous work of cleaning up debris and rebuilding homes and infrastructure as quickly as possible. As a recent news article points out:

“The fact is that the people who rebuild those areas—from Palisades to Malibu to Altadena—it’s immigrant construction crews,” said Pablo Alvarado, co-executive director of the National Day Laborer Organizing Network. “They’re the ones who are the second responders.”

Unfortunately, climate and fossil fuel-driven disasters are also contributing to a growing toll on people across the world, destabilizing economies, threatening livelihoods, health, water supplies, and food security. If we fail to sharply curtail heat-trapping emissions and invest in climate resilience, the numbers of people suffering harm will rise steeply, and many might even find themselves forcibly displaced both at home and abroad.

Rich nations like the United States (which is the leading historical contributor to global heat-trapping emissions) have the capacity and the responsibility to advance resilience at home and provide climate finance to help lower-income nations transition quickly to renewable energy and adapt to climate change. They also have a responsibility to help address climate loss and damage and displacement with a human rights-centered approach.

Hateful political rhetoric from President-elect Trump and his allies that demonizes and dehumanizes immigrants shows political leaders who are more interested in scoring cheap political points through fearmongering and fanning the flames of xenophobia, rather than acknowledging the basic humanity and incredible contributions of immigrants to our economy and our society.

This is not a new tactic. Across history, here in the United States and abroad, in uncertain economic times, extremists have often targeted immigrants and made harmful and deceptive claims blaming them for all the ills in society. Punching down, further marginalizing those who are fearful and may not have access to resources to defend themselves, is also a classic tactic of bullies and doesn’t solve the urgent problems facing our nation and our planet.

It’s up to all of us to stand up for the facts and stop allowing politicians to misuse the important issue of immigration policy to spew hateful lies as a convenient way to further their narrow interests. Mass detention and deportations will tear apart families, cause lasting trauma and harm, and set back health and education in immigrant communities especially for children, alongside undermining the the U.S. economy.  

We all know instinctively that leaving one’s familiar home and embarking on a dangerous journey to a faraway place, with very few resources and no guarantee of safety, is often an act of desperation—especially when bringing children. But for luck, this could be the plight of anyone in any country around the world.

Seeing our shared humanity and acting based on that principle is the best path forward on immigration and for our country of immigrants.

Adam McKay says the Jennifer Lawrence and Leonardo DiCaprio-starring satire resonates with a widespread feeling of being deceived by government and media

Adam McKay, writer-director of climate-crisis satire Don’t Look Up, says that the film’s popularity with viewers shows the popular will to tackle climate change, despite the critical brickbats the film attracted and political inertia around the issue.

McKay was speaking to the NME during the wildfire emergency that is currently affecting Los Angeles, which has included many high-profile victims from the Hollywood community. Saying that while Netflix, the film’s distributors, would not release definitive audience figures, he estimated that “somewhere between 400 million and half a billion” people saw it, and that “viewers all really connected with the idea of being gaslit”.

Big oil executive plans to celebrate Trump’s inauguration as California burns – though experts say climatic conditions are only getting more extreme

Donald Trump’s response to the catastrophic wildfires in Los Angeles has provided a stark prologue to how his US presidency will probably handle the growing threat of such disasters – through acrimony, brutal dealmaking and dismissal of a climate crisis that is spurring a mounting toll of fires, floods and other calamities.

As of Thursday, four fires, whipped up by wind speeds more typically found in hurricanes, have torched 63 sq miles (163 sq km) of Los Angeles, a burned area roughly three times the size of Manhattan, destroying more than 12,000 homes and businesses and killing at least 25 people. The Palisades and Eaton fires, the largest of the conflagrations that have turned entire neighborhoods to ash, are still to be fully contained.

As natural disasters make need to cut CO2 emissions clearer than ever, energy demand of AI systems is about to soar

Violent weather events have been top of the news agenda for weeks, with scientists and fact-based news organisations attributing their increased severity to climate breakdown. The scientists consulted have all emphasised the need to cut greenhouse gas emissions.

At the same time there are predictions about artificial intelligence and datacentres urgently needing vast amounts of new electricity sources to keep them running. Small modular nuclear reactors (SMRs) have been touted as the green solution. The reports suggest that SMRs are just around the corner and will be up and running in the 2030s. Google first ordered seven, followed by Amazon, Microsoft and Meta each ordering more.

Data for 2024 shows humanity is moving yet deeper into a dangerous world of supercharged extreme weather

Wildfires that blazed around the world in 2024 helped to drive a record annual leap in carbon dioxide levels in the atmosphere, surprising scientists. The data shows humanity is moving yet deeper into a dangerous world of supercharged extreme weather.

The CO2 level at the Mauna Loa observatory in Hawaii jumped by 3.6 parts per million (ppm) to 427ppm, far above the 280ppm level before the large-scale burning of fossil fuels sparked the climate crisis. The Mauna Loa observations, known as the Keeling curve, began in 1958 and are the longest running direct measurements of CO2.

Experts say climate crisis was likely responsible for a quarter of the dryness that fueled the fires’ rapid spread

As Los Angeles’s deadly wildfires continue to burn, a group of survivors is taking aim at the industry most responsible for fueling climate disasters: fossil fuels.

Residents impacted by the blazes lamented during a Thursday conference call losing their homes and communities and called for litigation and policies that could force big oil to pay for the damages. In the coming days, lawmakers will introduce legislation with that aim in mind.

The fires have been devastating for humans and taken a toll on nature, but many of California’s ecosystems will be able to regenerate

Beth Pratt has spent her career protecting Los Angeles’ mountain lions, which roam an area currently engulfed by wildfires. These apex predators, also known as cougars or pumas, share a scrubby landscape with lavish private homes and a dense network of roads. When major fires take out huge areas of open space, their options are limited.

“This is the LA area – these mountain lions can’t move into the Kardashians’ back yard,” says Pratt, California executive director for the National Wildlife Federation. “My heart is very heavy right now,” she says.
