Why aren't firefighters using seawater to put out the California fires?

LA sits right on the shore of the world’s largest ocean — so why isn’t seawater being used to fight the deadly fires?

The use of seawater to extinguish the scorching Los Angeles fires seems like a straightforward solution, but the technique faces a variety of complications despite the fact that the city sits on the shores of the Pacific Ocean.
While firefighters have sparingly tapped into the natural resource, issues like lack of reliable access, significant environmental impact, and corrosive qualities are key roadblocks to oceanwater’s consistent use in fighting the current inferno.
Depending on an individual species' salt tolerance, soil salinization can negatively affect plants by leading to a reduction of plant water intake, according to Soil Science Australia.
Former assistant chief for the California Department of Forestry and Fire Protection (Cal Fire) and retired fire analyst Tim Chavez told the Wall Street Journal that firefighters try to avoid saltwater for this reason.
“We try to avoid it because saltwater is a soil sterilizer. If you add salt to the soil, you’re not going to be able to grow anything there the next year,” he said.

While the long-term effects of salt in the soil are not yet understood, the dry conditions typical of California’s climate may allow salt to remain in the soil, which some species can’t “tolerate,” ecosystem ecologist at the Smithsonian Environmental Research Centre Patrick Megonigal wrote in The Conversation.
He noted that the seawater being dumped on the LA fires is “full-strength, salty ocean water”.
“Our experiment found that salt was causing clay and other particles to disperse and move about in the soil. Such changes in soil chemistry and structure can persist for many years,” Mr Megonigal added.
