Los Angeles Coastline Grapples with Post-Fire Damage
On a chilly January morning, Tracy Quinn surveyed the aftermath of the Palisades Fire, her eyes scanning the once-pristine shores now marred by burnt appliances and ash-darkened waters. “It was just heartbreaking,” Quinn, president of Heal the Bay, expressed her dismay as she observed the damage extending along the coastline beyond Los Angeles.
Fire’s Impact Reaches the Ocean
As firefighters continue clearing the hazardous debris from the wildfires, which consumed homes and businesses alike, the bigger picture is growing grimmer, especially for marine life. The proximity of the burned structures to the ocean throws up numerous environmental concerns—mainly, how will all that tainted ash affect the sea?
Mara Dias, who looks after water quality at the Surfrider Foundation, was quick to flag the risk of ocean water pollution. Winds ferried the smoke and ash far out to sea during the fire outbreak in early January. Dias explains, “When the rain comes, it’s not just water—it carries with it all sorts of nasty stuff from ash to heavy metals.”
The Chemical Soup Created by Runoff
- Contaminants: Rain picks up various harmful substances, including phosphates, nitrates, and heavy metals, as it flows into the ocean.
- Mudslides: Recent mudslides have made matters worse, introducing even more debris into the marine environment.
- Marine Life at Risk: The contaminated runoff could disrupt marine ecosystems and even enter the human food chain via seafood.
Efforts are underway to mitigate these effects. Los Angeles County officials have deployed barriers and bags to catch as much debris as possible. Meanwhile, the waters are being tested for a slew of dangerous substances. Although last month’s tests didn’t trigger immediate alarm, the long-term effects remain a concern.
Science on the Sea
Julie Dinasquet, a marine ecologist with Scripps Institution of Oceanography, points out the complexity of the situation. Their team noticed debris as far as 100 miles offshore during the fire. “Imagine your electronics burning, that sort of a smell on the water,” she recalled, which is far from normal or healthy.
Research continues into how deep and quickly these pollutants are settling in the ocean bed, and what their journey through the marine ecosystem looks like. While forest fires might enrich the seas with nutrients that boost plankton growth, the toxic ash from urban fires adds harmful substances like lead and asbestos—bad news for marine life and potentially for humans too.
What’s Next for Our Beaches and Seas?
The ongoing cleanup and scientific research are crucial as Los Angeles looks to protect its natural landscapes and communities. With everything from local surfing conditions to the broader ecological balance at stake, the effects of the Palisades Fire could reshape how we manage urban coastal areas in the face of rising wildfire risks.
Here’s what that means for us: It’s a wake-up call to look after our land and seas better. Because as Quinn puts it, “What happens on land doesn’t stay on land—it reaches our seas too.”
