Your support will allow us to continue testing our beaches effected by the Palisades Fire for toxins and contaminants.
We are testing for: Heavy Metals, Asbestos, Dioxins, Furans, Mercury, Volatile Organic Compounds, Pesticides, Herbicides, Pyrethroids, and Polychlorinated biphenyls (PCBs).
The Coastal Alliance is a nonprofit public benefit corporation dedicated to protecting and restoring marine ecosystems through science-driven advocacy, community engagement, and policy initiatives. Our mission is to safeguard coastal environments, address pollution threats, and promote sustainable practices to ensure the long-term health of our oceans and marine life.
We achieve this by:
We recognize the extreme devastation the recent fires have caused—homes reduced to ash, businesses lost, and lives upended. The urgency of cleanup is undeniable. But declaring the coastline safe based on incomplete data is premature, irresponsible, and misleading.
For months, the Palisades Fire debris—contaminated with carcinogens like asbestos, dioxins, and heavy metals—has polluted our beaches, leaching into the soil and ocean. Yet, no large-scale cleanup effort was conducted.
Los Angeles County officials have been assuring the public that our beaches and waters are safe—without conducting the necessary level of testing to justify such claims. Initial assessments have been limited in scope, lacking the diversity, frequency, and transparency needed to make a conclusive determination.
Without extensive and ongoing environmental testing, the true impact of wildfire debris contamination remains unknown—yet hazardous waste continues to accumulate at our shores.
The Palisades Fire left behind toxic remnants—carcinogenic ash, heavy metals, asbestos, dioxins, and other hazardous pollutants. These materials continue to accumulate on our beaches and in storm drains, posing a serious risk to public health, marine life, and our coastal ecosystems.
Yet, instead of implementing a rapid-response containment and cleanup plan, officials have failed to prevent contaminated debris from washing into the ocean with every high tide. Without proper removal, wildfire ash and hazardous materials are continuously reintroduced into the marine environment, increasing the long-term damage to our beaches and wildlife.

We began collecting samples immediately after the fire started, not with the intent of conducting the broader environmental analysis it has since evolved into, but to assess the impact of the fire on the western snowy plover, a small, endangered ground-nesting shorebird that inhabits Santa Monica’s beaches. Given the plover’s vulnerability to habitat disturbances, we wanted to document any immediate effects the fire debris might have had on their nesting and foraging areas.
Weeks pasted without any information, our elected leaders and government agencies failed to test and concerns about hazardous contamination grew, our focus expanded to include the larger environmental and public health implications of the fire’s aftermath.
Your support will allow us to continue testing our beaches effected by the Palisades Fire for toxins and contaminants: Heavy Metals, Asbestos, Dioxins, Furans, Mercury, Volatile Organic Compounds, Pesticides, Herbicides, Pyrethroids, and Polychlorinated biphenyls (PCBs).
The Southern California wildfires have deeply affected individuals and entire communities, with many experiencing devastating losses – loss of life, loved ones, homes, and livelihoods – leaving a profound and lasting impact.
Some of the effects will also impact California’s ecosystems. However, the size and scale of Southern California wildfires are unprecedented. The urban location lends to more toxic runoff with a greater potential to harm coastal and marine ecosystems that could pose significant threats to California’s health, economy, and identity.
Detecting such wildfire effects on whale and dolphin populations can sometimes take years to observe and confirm. Valuable time may be lost waiting for such confirmation, during which conservation interventions should be implemented.
What Is Domoic Acid?
Domoic acid is a potent neurotoxin produced by certain harmful algal blooms, particularly those involving Pseudo-nitzschia australis. This toxin accumulates in small fish, such as sardines and anchovies, which are primary prey for marine mammals like sea lions.
Once ingested in significant amounts, domoic acid attacks the brain and heart, leading to seizures, neurological impairment, and even heart failure. If untreated, it often results in permanent brain damage. While the toxin naturally clears from an animal’s system over time, repeated exposure can lead to long-term and more severe effects.
When affected marine mammals receive care before substantial damage occurs, they can often recover. Treatment typically involves administering fluids to help flush out the toxin, providing a diet free from domoic acid, and managing seizures with anti-convulsant medications similar to those used in human medicine.
Domoic acid poisoning has been widely reported in sea lions, otters, cetaceans, and other marine mammals.
Domoic acid remains a significant threat to marine ecosystems, highlighting the need for monitoring harmful algal blooms and protecting vulnerable wildlife from exposure.
Recent wildfires in Los Angeles have impacted Santa Monica Bay's water quality, leading to elevated nutrient levels, a persistent brown foam, and a dangerous algal bloom killing marine mammals.
Kelp forests, vibrant underwater ecosystems, thrive in the Santa Monica Bay, providing habitat and food for numerous marine species.

With its sun-drenched lifeguard towers, bronzed surfers and bikini-clad volleyball players, Will Rogers State Beach is one of the most recognizable stretches of sand in the world thanks to the global cult classic "Baywatch".
But now the iconic beach is surrounded by the ruins of burned homes and palm trees, its parking lot a sorting ground for hazardous waste from the wildfires. The beach babes have been replaced by Environmental Protection Agency crews in hazmat suits sifting through melted electric car batteries and other hazardous waste before it's trucked away to landfills.
The EPA provided us with a tour of the hazardous debris sorting site at the Will Rogers Beach parking lot, where lithium battery waste from the Palisades and Eaton fires is being processed. Here, you can see firsthand how lithium batteries are handled in close proximity to sensitive ecological habitats

Red Tide and Toxic Runoff:
Fire debris and runoff from the Santa Cruz Mountains flowed into Monterey Bay, increasing nutrient loads and potentially contributing to a harmful algal bloom (red tide).
Scientists at the Monterey Bay Aquarium Research Institute (MBARI) found elevated nutrients and organic pollutants in nearshore waters.
Impact on Kelp Forests and Fisheries: Ash deposits coated kelp forests and intertidal zones, affecting photosynthesis and smothering marine organisms.
Some commercial fisheries temporarily halted shellfish harvesting due to concerns about contamination from wildfire-related toxins.
Debris Flow into the Ocean: After heavy rains, toxic ash and debris from the Woolsey Fire washed into the Pacific Ocean, affecting beaches from Malibu to Ventura.
Reports found high levels of heavy metals, PCBs (polychlorinated biphenyls), and other toxins in runoff reaching the ocean.
Surfers and swimmers were advised to stay out of the water for weeks due to high bacterial levels and contamination risks.
Impact on Marine Life: Studies detected hydrocarbons and toxic compounds in coastal waters, which can harm fish and shellfish populations.
The Santa Monica Baykeeper and Heal the Bay raised concerns about long-term contamination of marine food webs.
Toxic Ash and Debris: The Camp Fire, which destroyed nearly the entire town of Paradise, left behind hazardous ash and debris containing heavy metals (lead, arsenic, mercury), asbestos, and toxic compounds from burned homes, vehicles, and industrial sites.
Public Health Concerns: Residents and cleanup crews were warned about inhaling particulate matter and exposure to toxic debris. Testing revealed elevated levels of arsenic and lead in some areas.
Water Contamination: The fire melted underground plastic pipes, leading to benzene contamination in the town’s water supply. It took years and extensive remediation to restore safe drinking water.
Massive Debris Flows into the Santa Barbara Channel: Heavy post-fire rains triggered massive debris flows (mudslides) in Montecito, dumping tons of burned debris and sediment into the Santa Barbara Channel.
The Channel Islands National Marine Sanctuary reported ash and sediment deposits smothering rocky reefs, potentially affecting biodiversity.
Airborne Toxic Particles: Fire-related air pollution settled over the ocean, raising concerns about PAHs (polycyclic aromatic hydrocarbons) and dioxins entering marine food webs.
Hazardous Debris Management: The fire destroyed thousands of structures, leading to massive amounts of toxic debris. FEMA and the EPA had to coordinate large-scale hazardous waste cleanup efforts to prevent public exposure.
Wildlife Impact: Testing showed elevated heavy metals in nearby lakes and rivers, affecting fish populations and potentially posing risks to humans who consumed them.
Airborne Asbestos and Lead: Burned structures, particularly older homes, released asbestos and lead-based paint particles into the air and soil. Cleanup efforts had to follow strict hazardous waste protocols.
Water System Damage: Like Paradise, the fire melted PVC pipes, releasing volatile organic compounds (VOCs) into the water supply. Some areas had water contamination for over a year.
Soil and Waterway Contamination: The fire burned through land containing industrial and agricultural sites, leading to the release of pesticides, heavy metals, and other pollutants into the soil and waterways.
Health Effects on First Responders: Firefighters and cleanup workers experienced respiratory issues due to prolonged exposure to toxic ash and airborne contaminants.
Toxic Stormwater Runoff into Santa Monica Bay: The fire burned large areas in the San Gabriel Mountains, and later rains washed toxic ash, debris, and charred vegetation into the LA River and storm drains.
This led to a surge in contaminants reaching Santa Monica Bay, raising bacteria and heavy metal levelsbeyond safe swimming thresholds.
Threats to Drinking Water: Post-fire rains caused ash and debris to wash into reservoirs and watersheds, increasing turbidity and introducing harmful chemicals.
Heavy Metal Contamination: Tests found lead, arsenic, and other metals in burned vehicle and building debris, prompting state officials to issue strict disposal guidelines.
Over the past few days, it’s been impossible to avoid seeing the tell tale signs of wildfire ash and debris accumulating along the coastline of Santa Monica. At low tide in particular, endless thick lines of ash particles are easily visible against the golden sands that form our big, beautiful beaches.
Protesters marched against the Environmental Protection Agency’s (EPA) plan to use the Will Rogers State Beach parking lot as a hazardous waste processing site for debris from the Palisades Fire on Sunday.
Over a hundred demonstrators gathered at Will Rogers State Beach on Sunday morning to protest the Environmental Protection Agency’s controversial decision to use the area as a toxic waste sorting site to process debris from the Palisades Fire.
