Why can't they use sea water in California?

California can't easily use seawater for everything (like drinking or general supply) due to its high salt content, which is bad for equipment, agriculture, and ecosystems, requiring expensive desalination; however, firefighters do sometimes use it as a last resort for wildfires, but it's problematic because salt corrodes gear and harms soil, hindering future plant regrowth, though it's often used from planes for immediate fire suppression when fresh water isn't available.

Why can't California use salt water?

Saltwater corrodes firefighting equipment and may harm ecosystems, especially those like the chaparral shrublands around Los Angeles that aren't normally exposed to seawater. Gardeners know that small amounts of salt – added, say, as fertilizer – does not harm plants, but excessive salts can stress and kill plants.

Why didn't they use ocean water for LA fires?

“Fire companies are not going to do it,” he says, “as they know fire pumps are sophisticated metal devices and seawater is very corrosive.”

Why can't you use salt water to stop fire?

It turns out that seawater is not only unfit for consumption: it also cannot be used to extinguish fires. It is extremely salty, its density and viscosity are higher, its freezing point is lower, and its boiling point is higher.

Why can't they put out the fires in California?

Lack of Detection. California forest fires often start in remote areas that are lush with trees and brush. That's why it can be anywhere from hours to days before these fires are detected, and at this point, they're large enough that they're difficult to control.

Can Seawater Fix California’s Drought?

What is the 5 foot rule in California?

California's "5-foot rule," also known as "Zone Zero," requires creating an ember-resistant perimeter, typically using non-combustible materials like gravel or pavers and removing flammable vegetation (mulch, dead leaves, certain plants) within five feet of a home in high-risk fire areas to prevent embers from igniting structures, with new state rules finalized in 2025 and local ordinances in cities like Berkeley already active, aiming to reduce wildfire spread and damage.
 

Can firefighters use ocean water to fight fires?

The short answer is yes, they can — but it's more complicated than simply going to the beach to transport water to the hillsides of L.A.

What is the 30/30/30 rule for fire?

A CBC meteorologist reminded his audience of the 30-30-30 rule of thumb for Canadian fire — fires burn actively with 30 C temperature, 30% humidity, and 30 kph winds.

What causes 90% of all fires?

About 90% of all wildfires, and a large portion of structure fires, are caused by human activity, including unattended campfires, arson, discarded cigarettes, equipment use, and electrical issues like overloaded outlets, with only a small percentage naturally occurring from lightning. Human negligence in managing heat sources like cooking, smoking, and electrical systems is a major driver, turning preventable incidents into disasters.
 

Why doesn't California filter ocean water?

The construction and operating costs of seawater desalination plants are high, making the cost of seawater desalination much higher than other sources of water resources, such as groundwater and river water. Secondly, the sea water desalination process may cause harm to marine life.

Why can't they just put the fires out?

It's just not feasible due to the types of fuels, the amount of heat they hold, and the access and egress issues on and near the fire perimeter. The #ElkFire will likely take a major season- ending event like snow to actually go "out". Right now, the ultimate goal is containment.

Why is California getting so many wildfires?

Yu: One of the most significant factors is climate change. Warmer temperatures, reduced precipitation or a changed rainfall season and longer fire seasons have dried out California's landscapes, increasing the potential for ignition and rapid fire spread.

Why can't we drink 97% of the water on Earth?

We can't drink 97% of Earth's water because it's saltwater in the oceans, which is too salty for our bodies and would dehydrate us; the remaining freshwater is mostly frozen in glaciers or deep underground, leaving only a tiny, accessible fraction for drinking, agriculture, and other needs. Drinking seawater makes you thirstier as your kidneys try to flush out the excess salt, a process that uses more water than you consume, leading to dehydration and potential death.
 

Is California becoming unlivable?

America has been under a global climate crisis for a long period of time – chaos is now interfering with our livable climate and if we don't do anything to preserve it, parts of California could submerge as soon as 2040. California is becoming unlivable, and we're not just talking about the traffic.

Which ocean has no salt water?

The ocean around Antarctica has a low salinity of just below 34 ppt, and around the Arctic it is down to 30 ppt in places. Thawing icebergs add freshwater – icebergs that have broken off ice sheets formed over land do not contain salt, and the freezing of seawater into ice floes removes more salt.

What is the golden rule of fire?

The golden rule of fire safety, "Get out, stay out, and call for help," serves as a lifesaving strategy to ensure that in the event of a fire, individuals take the right steps to protect themselves.

What is the 4% rule in fire?

The FIRE 4% rule is a guideline for early retirement that suggests you can safely withdraw 4% of your total savings in the first year of retirement, then adjust that amount annually for inflation, with the goal of your money lasting 30 years or more without running out. It's a popular starting point for the Financial Independence, Retire Early (FIRE) movement, but many experts suggest personalizing it for longer retirements, market changes, and taxes, often recommending a more flexible, dynamic approach.
 

Are the Canadian fires still burning in 2025?

Canadians across the country showed their generosity by donating to wildfire disaster relief through the Canadian Red Cross 2025 Wildfire Appeals in Saskatchewan, Manitoba, and Newfoundland and Labrador. Even as the most active wildfire period has passed, some regions are still facing active fires.

Is ocean water drinkable if you boil it?

No, you cannot drink ocean water just by boiling it; boiling kills germs but leaves the salt behind, which actually concentrates and makes it more dangerous, leading to severe dehydration and kidney problems, so you need to use distillation to collect the steam for fresh water. To get safe drinking water, you must distill it by capturing and condensing the pure water vapor that rises, leaving the salt and contaminants behind in the original pot. 

Why can't they put out wildfires?

Moving heavy machinery safely through a forest poses an immense number of issues. Other hazards from creating control lines, such as dangerous vegetation, trees that are hazardous to cut down, and insects or animals, can prove both time consuming and unsafe. Furthermore, wildfires are also unpredictable.

Why is California diverting water to the ocean?

California diverts water to the ocean primarily to keep the Sacramento-San Joaquin Delta fresh, preventing seawater intrusion that would contaminate urban and agricultural water supplies, and to support critical ecosystems for fish like salmon, though excess storm flows often overwhelm storage, leading to releases for flood control and environmental needs, sparking debate over water waste versus necessity. 

What is the #1 killer of firefighters?

The leading cause of firefighter fatalities is sudden cardiac events, often stemming from overexertion, strain, and stress, which manifest as heart attacks, though occupational cancer is a significant and growing concern. These physiological stressors, combined with exposure to toxins, heat, and irregular sleep, trigger cardiovascular events, making heart health paramount in firefighter safety. 

Can super scoopers use ocean water?

These planes can scoop 1,500 gallons of water from large bodies of water, like the ocean, in just seconds.

Why doesn't California have water?

Due to the lack of reliable dry season rainfall, water is limited in the most populous U.S. state. An ongoing debate is whether the state should increase the redistribution of water to its large agricultural and urban sectors, or increase conservation and preserve the natural ecosystems of the water sources.
