As wildfire crews battled the Dragon Bravo Fireplace at the Grand Canyon’s North Rim in July 2025, the air grew to become poisonous.
A chlorine fuel leak had erupted from the park’s water remedy facility because the development burned, forcing firefighters to drag again. The water remedy facility is a part of a device that attracts water from a delicate spring. It’s the one water supply and device for the park amenities on each rims, together with customer accommodation and park provider housing.
The hearth additionally broken one of the most house’s water pipes and gear, leaving hearth crews to depend on a fleet of huge water vans to haul in water and elevating issues about contamination dangers to the water device itself.
Via mid-August, Dragon Bravo was once a “megafire,” having burned over 140,000 acres, and was once one of the vital biggest fires in Arizona historical past. It had destroyed greater than 70 constructions, together with the long-lasting Grand Canyon Hotel, and despatched smoke around the area.

Wildfires like this are increasingly more affecting water provides around the U.S. and making a compounding disaster that mavens in water, utilities and emergency control are simplest starting to strive against with.
A trend around the West
Sooner than 2017, when the Tubbs Fireplace burned via neighborhoods at the fringe of Santa Rosa, California, maximum analysis at the nexus of wildfire and water had concerned with problems comparable to drought and the way local weather trade results ecosystems.
The Tubbs Fireplace destroyed 1000’s of constructions and likewise melted plastic water pipes. After the fireplace, a resident’s criticism concerning the style and smell of faucet water ended in the invention that the fireplace’s harm had offered contaminants together with benzene, a carcinogen, into portions of the general public water device.
It briefly changed into glaring that the wear and tear came upon on the Tubbs Fireplace was once no longer distinctive.
Identical harm and pollution have been came upon in every other California water device after the 2018 Camp Fireplace destroyed a lot of Paradise, a the town of over 25,000 other people.
The checklist of incidents is going on.
In southern Oregon, the 2020 Almeda Fireplace broken water pipes in constructions, leaving water to go with the flow freely. That contributed to low device force simply when other people combating the fireplace wanted the water.

In Colorado, the 2021 Marshall Fireplace burned via city water traces, harmful six public drinking-water programs in conjunction with greater than 1,000 constructions within the Boulder suburbs. All six programs misplaced energy, which in some instances ended in a lack of water force, hampering firefighting.
As firefighters labored at the Marshall Fireplace, water device operators raced to stay water flowing and contaminants from being transported into the water programs. However exams nonetheless detected chemical contamination, together with benzene, in portions of the programs a couple of weeks later.
Then, in January 2025, the Los Angeles fires supercharged issues about water and wildfire. As firefighters raced to place out more than one fires, hydrants ran dry in some portions of the area, whilst others at upper elevations depressurized. In the end, over 16,000 constructions have been broken, resulting in insured losses estimated to be as excessive as US$45 billion.
Water provides are a very powerful to combating fires. In towns, hearth crews like this one scuffling with the Palisades Fireplace in Los Angeles in January 2025 can ceaselessly depend on hydrants. However water programs can lose force and doubtlessly the ability to run their pumps throughout fires.

Water infrastructure isn’t simply collateral harm throughout wildfires – it’s now a central fear.
It additionally raises the query: What can citizens, first responders and decision-makers slightly be expecting from water programs that weren’t designed with these days’s failures in thoughts?
Addressing the rising hearth and water problem
Whilst no two water programs or fires are the similar, just about each and every water device part, starting from garage tanks to pipelines to remedy vegetation, is vulnerable to harm.
The Grand Canyon’s Roaring Springs device exemplifies the complexity and fragility of older programs. It provides water to each rims of the park via a decades-old community of gravity-fed pipes and tunnels and comprises the water remedy facility the place firefighters have been pressured to retreat on account of the chlorine leak.
Many water programs have prone issues inside of or close to flammable wildlands, comparable to uncovered pump homes which might be a very powerful for pulling water from decrease elevations to the place it’s wanted.
A stand pipe at Zorthian Ranch in Altadena, Calif., failed throughout the January 2025 hearth there, making it much more tough for Alan Zorthian to struggle the flames sweeping throughout his belongings. He used a pump drawing water from a swimming pool to take a look at to struggle the flames, however a lot of constructions have been destroyed.

As well as, hazardous fabrics comparable to chlorine or ammonia could also be saved on-site and require particular issues in excessive hearth threat spaces. Team of workers capability is ceaselessly restricted; some small utilities rely on a unmarried operator, and budgets could also be too constrained to modernize growing older infrastructure or put into effect hearth mitigation measures.
As local weather trade intensifies wildfire seasons, those vulnerabilities can transform crisis dangers that require making water infrastructure a extra integral a part of combating and making ready for wildfires.
Techniques to lend a hand everybody get ready
As a researcher with Arizona State College’s Julie Ann Wrigley World Futures Laboratory, I’ve been running with colleagues and hearth and water programs mavens on methods to lend a hand communities and hearth and water managers get ready.
Listed here are a couple of vital courses:
Prioritizing fire-resistant development, higher shielding of chemical compounds and, in some instances, decentralizing water programs can lend a hand offer protection to important amenities, in particular in high-risk zones. Having backup energy provides, cellular remedy programs and trade water resources are crucial to supply extra safety within the face of a wildfire.
Emergency command protocols and interagency coordination are most efficient after they come with water utilities as crucial companions in all stages of emergency reaction, from making plans to reaction to restoration. Fireplace crews and water operators too can take pleasure in joint coaching in emergency reaction, particularly when device failure may just obstruct firefighting itself.
Long run, protective upstream watersheds from critical hearth by means of thinning forests and the use of managed burns, in conjunction with erosion keep watch over measures, can lend a hand deal with water high quality and cut back water air pollution within the aftermath of fires.
Smaller and extra remoted programs, in particular in tribal or low-income communities, ceaselessly need help to plot or put into effect new measures. Those programs might require technical help, and regional reinforce hubs may just reinforce communities with further assets, together with group of workers and gear, so they may be able to reply briefly when crises strike.
Taking a look forward
The Dragon Bravo Fireplace isn’t only a wildfire tale, it’s additionally a water tale, and it alerts a bigger, rising problem around the West. As hearth seasons increase in dimension and complexity, the overlap between hearth and water will simplest develop.
The Grand Canyon hearth gives a stark representation of the way wildfire can escalate right into a multifaceted infrastructure disaster: Fireplace can harm water infrastructure, which in flip limits firefighting functions and stresses water provides.
The query isn’t whether or not this will likely occur once more. It’s how ready communities can be when it does.
