From devastating wildfires and toxic algal blooms to plastic pollution and climate change, California’s coastline, communities, and wildlife are at risk like never before. For endangered species like the sunflower sea star, giant sea bass, and tidewater goby, Heal the Bay’s science, education, and advocacy is a lifeline that can help save them from extinction. But our work is at risk, too.

That’s why this Giving Tuesday, Heal the Bay called on supporters to join us and our animal ambassadors to protect what’s endangered. Every gift helps save our work — and the endangered species who rely on it — from extinction.

Read on to learn more about how donations help support our endangered animal ambassadors.

Meet Heal the Bay’s Animal Ambassadors

Heal the Bay Aquarium cares for several endangered species, including a sunflower sea star, giant spotted sea bass named “Gordita”, and tidewater gobies rescued from waters impacted by the Palisades Fire.

Through education, advocacy, and science, including restorative aquaculture, Heal the Bay is helping save these species from extinction and restore their ecosystems. Aquarium visitors can meet some of them from 12-4 p.m. every Saturday and Sunday under the Santa Monica Pier.

The Sunflower Sea Star

 

Sunflower sea stars are one of the bay’s most important species. But after sea star wasting devastated populations in the 2010s, they’re now functionally extinct in California.

At Heal the Bay Aquarium, we are honored to care for one of only a few female sunflower sea stars in captivity in the entire state. We’re making groundbreaking strides in sunflower sea star recovery, with the long-term goal of raising and returning this endangered species to Santa Monica Bay so the ecosystem can thrive again. Our sea star’s story is one of resilience and of the power of advocacy, as she plays a vital role in this groundbreaking repopulation research.

Protecting this sea star means protecting the policies and advocacy that could help save her species.

The Giant Sea Bass

Giant sea bass are the largest bony fish along California’s coast, growing up to nine feet long and weighing as much as a full-sized grizzly bear. They can also live to 75 years old. Overfishing in the early 1900s pushed them to the brink, and today, they remain critically endangered.

“Gordita”, our resident giant sea bass, is one of Heal the Bay Aquarium’s most beloved ambassadors. Each year, she helps thousands of local students discover how protecting our coastline creates ripples far beyond the water.

The Tidewater Goby

Tidewater gobies are tiny but mighty endangered fish that play a big role in the food webs of California’s marshes, lagoons, creeks, and estuaries. Despite their resilience, they’ve been severely impacted by coastal development, habitat degradation, and the alteration of natural water flows.

After the January 2025 wildfires impacted the waters of Topanga Lagoon, Heal the Bay Aquarium helped care for a rescued a group of tidewater gobies from the contaminated conditions. We cared for them until their habitat recovered, and most have now been safely released back into the wild. Our team continues to care for the remaining gobies and is working to help strengthen and restore this fragile population.

Through our partnership with Santa Monica College, students in the Sustainable Aquaculture Certification Program are being introduced to these rescued gobies and learning how restorative aquaculture can support endangered species recovery.

Protecting at-risk species starts with science: the research, monitoring, and restoration work Heal the Bay uses every day to safeguard our coastal watersheds and the animals that depend on them.

How Our Work Is Helping

At Heal the Bay, we use science, education, and advocacy to protect our coast, communities, and wildlife through initiatives including:

  • Water-Quality Monitoring: Regular testing identifies pollution hotspots, monitors over 700 beaches for fecal indicator bacteria, and provides data that drives policy change.
  • Restorative Aquaculture: Breeding and release programs help vulnerable species recover while scientists learn what these animals need to thrive in changing ocean conditions.
  • Policy Advocacy: From plastic reduction to climate resilience strategies, science-informed advocacy ensures that regulations reflect the needs of our communities, wildlife, and ecosystems.
  • Education Programs: When students connect with marine life through hands-on experiences, they become the advocates and scientists who’ll protect these species for decades to come.

Why This Moment Demands Action

Federal protections for endangered species and critical habitats face ongoing challenges. Meanwhile, climate change and disasters accelerate.

When funding disappears, so do the knowledge, data, and community relationships that make conservation work. Despite mounting challenges, we remain optimistic. The endangered species that call Southern California’s coast home can recover, but only if the work protecting them continues.



An angler uses a net to catch fish off the Santa Monica Pier

Decades of toxic DDT and “forever chemicals” still linger in Santa Monica Bay, putting subsistence and recreational anglers at risk. Heal the Bay is urging the Office of Environmental Health Hazard Assessment to call for new testing and update safety standards to protect our local anglers.

California has a responsibility to protect its residents from toxic pollution. Sign the petition to urge OEHHA to take the necessary steps to keep our angler community safe.

Sign Petition



The 2025 legislative session was a tough one for California’s environmental advocates. Against the backdrop of devastating wildfires, raids impacting California’s immigrant communities, severe budget constraints across the state, and federal rollbacks that weakened environmental protections, many of our state’s most important environmental bills faced uphill battles as legislators were forced to reshuffle their priorities. Still, amid the challenges, we saw meaningful wins for ocean health and waste reduction. And we’re hopeful that a number of bills still in the pipeline will pass next year.  

Below is a breakdown of the environmental legislation we’ve been tracking this year and where it stands as we head into 2026.  

Major Wins for Our Environment 

AB 1056 — Phasing Out Gillnets for Good 

We’re thrilled to share a major victory for ocean conservation, and one that Heal the Bay has proudly supported every step of the way through support letters and direct lobbying on California Ocean Day in Sacramento. Governor Gavin Newsom signed AB 1056 into law, which will phase out the last remaining set gillnets in California.  

Set gillnets are mile-long nets anchored to the ocean floor that often entangle high numbers of marine wildlife. This destructive gear dates back to 1915, so this victory has been a long time coming. Congratulations to our friends at Oceana, Resource Renewal Institute, and the Office of Assembly Member Steve Bennett who sponsored and championed this milestone legislation. Read the press release here. 

SB 279 — Scaling Up Composting Statewide 

Another bright spot this session was the passage of SB 279, which takes a major step toward building California’s circular economy by expanding access to composting programs across the state. Composting not only curbs greenhouse gases but also enriches soils, conserves water, supports local agriculture, and helps reduce pollution by making it even easier to use and dispose of compostable products, making this a win for both people and planet. This law strengthens California’s ability to divert organic waste from landfills, reducing methane emissions and helping cities and counties meet their climate goals.  

Missed Opportunities 

AB 823 — Expanding the Microbead Ban 

We were deeply disappointed to see AB 823, vetoed by Governor Newsom. This bipartisan bill that passed both the Assembly and Senate would have expanded California’s existing microbead ban to include cosmetics, further protecting our waterways from harmful microplastics. The governor’s veto cited procedural concerns, but this decision undermines years of progress toward a plastic-free future.  

This was an important measure to stop microplastics at the source. Heal the Bay will continue to push for stronger action on this front next year. 

SB 45 — Tethered Caps on Bottles 

SB 45 would have required tethered caps on beverage bottles, preventing loose plastic caps from polluting our beaches and waterways. This solution already exists in other parts of the globe, with producers adopting the tethered cap design. Unfortunately, the bill died earlier this spring. But it won’t stop our continued advocacy for targeted solutions and bigger, more comprehensive plastic-reduction policies that keep plastics out of our environment.  

Bills Still in the Pipeline 

Several promising bills didn’t cross the finish line this year but will return for consideration in 2026. We’ll be leveraging our advocacy efforts next year to ensure these proposals around pollution prevention, water justice, and waste reduction don’t stall out for good. 

AB 762: Proposes a ban on disposable vapes to protect public health and reduce e-waste.  

SB 561: Would create a manufacturer responsibility program for safely managing the disposal of unused emergency distress flares — explosives that poses serious safety risks. 

SB 501: Would establish a producer responsibility program for household hazardous waste and require producers of that waste to provide a convenient collection and disposal system.   

SB 350: Introduces the creation of a statewide water rate assistance program to ensure access to affordable, clean water.  

SB 601: Would reaffirm California’s Clean Water Act protections following federal rollbacks.  

AB 638: Was authored to provide state guidance for safely using stormwater as a non-potable water source.  

Looking Ahead 

Despite the challenges of this legislative season, our commitment to protecting our coast and communities remains as strong as ever. Every session brings new opportunities to advance policies that protect biodiversity, reduce pollution, safeguard clean water, and build a more sustainable Los Angeles. 

We’ll continue advocating alongside our partners and community members to advance these bills that are still in the pipeline and ensure that California remains a global leader in ocean conservation and climate action. 

Stay tuned for action alerts, local advocacy opportunities, and ways to raise your voice for clean water and healthy ecosystems.

Water quality at many West Coast beaches and Los Angeles freshwater sites improved over the past year, according to Heal the Bay’s annual Beach Report Card and River Report Card, released today. The reports’ findings highlight both progress and persistent risks for millions of people who swim, surf, and play in local waters each year.

A near-record 62 beaches earned a spot on the nonprofit’s coveted Honor Roll with perfect A+ scores in 2024-2025. It was the highest Honor Roll count in over a decade. Only 12 beaches made the Honor Roll last year and just two in the 2022-2023 report. Freshwater sites also saw gains in the 2024 River Report Card, with 24 out of 35 graded safe for recreation.

But the good news comes with caveats. Climate “whiplash” is making water quality more variable. Dry years are generally bringing cleaner water — with less bacterial pollution washing into waterways — while wet years are dragging down grades. Persistent hotspots like the Santa Monica Pier, several San Diego County beaches, and the lower L.A. River remain unsafe despite improvement efforts. And January’s wildfires added a new layer of concern, underscoring the importance of Heal the Bay’s work to expand testing and monitoring in the wake of the disasters. “More beaches and rivers were safe for swimming than we’ve seen in years,” said Annelisa Moe, Heal the Bay’s Associate Director for Science & Policy. “But persistent pollution hotspots and new threats from climate extremes like wildfires make it clear that we can’t take clean water for granted. That’s why Heal the Bay is pushing for stronger infrastructure and policies to protect public health and our waterways.”

Annual Beach Report Card

Annual River Report Card

 

Biggest Takeaways

1. Dry weather meant cleaner water, but climate extremes loom large. Nearly 9 in 10 beaches and more than two-thirds of freshwater sites were safe for recreating last year, likely thanks to a dry summer and winter. But progress is uneven, as climate extremes drive swings in bacteria levels and highlight the urgent need for resiliency planning.

2. Persistent hotspots show where work is most urgent. Trouble spots like the Santa Monica Pier, beaches along the U.S.-Mexico border, and stretches of the lower L.A. River remain unsafe year after year. Outdated sewage and stormwater systems, polluted runoff, and poor water circulation all contribute, underscoring the need for stronger infrastructure and controls.

3. Wildfires add layered threats to water quality. The January 2025 Palisades and Altadena fires washed ash, debris, and toxins into local waters, and early results suggest a link with worsened bacteria levels. Since Beach and River Report Cards only measure fecal indicator bacteria, more study is needed to assess impacts from wildfire-related contaminants like heavy metals. Heal the Bay is advancing this work through its Ash to Action initiative.

About the Reports

What are the Beach and River Report Cards?

Heal the Bay’s 35th annual Beach Report Card and 7th annual River Report Card take a deep dive into bacterial pollution trends at more than 700 beaches along the Pacific Coast and 35 freshwater sites in Los Angeles.

Each site gets an annual letter grade from A to F based on how much fecal indicator bacteria is found in the water during each testing season (summer dry weather, winter dry weather, and annual wet weather). The bacteria come from stormwater runoff, failing sewage systems, or other pollution, and they can cause illnesses like stomach flu, ear infections, upper-respiratory infections, and rashes. In short: The lower the letter grade, the higher the risk of getting sick.

All county health departments in California are required to test beach water quality samples for three types of indicator bacteria at least once a week during the summer season. Many counties also monitor heavily used beaches year-round. Heal the Bay compiles and analyzes the data to produce the annual Beach Report Card.

Freshwater sites don’t have the same monitoring requirements, so Heal the Bay deploys its own scientists with the Stream Team — students trained in field and lab techniques — and works with other local groups and municipalities to collect and analyze samples throughout the summer (May to September).

How is this different from the reports shared in May?

In May, Heal the Bay released a first look at this year’s Beach Report Card with a list of California’s Honor Roll beaches and bottom 10 Beach Bummers. Today’s release expands on those lists with deeper insights and annual grades for more beaches across California, Oregon, Washington, and Baja California.

The 2024 River Report Card was released today and includes annual grades and insights into 35 freshwater sites across Los Angeles.

How did the wildfires impact the reports?

The January wildfires delayed the full report release as Heal the Bay scientists worked to quickly assess how toxins from fire debris were impacting beach and water quality and notify the public about potential health risks beyond bacteria pollution. More information about Heal the Bay’s post-fire response work is available in a special section of the Beach Report Card (pgs. 52-54).

Note: The water-quality grades released today only reflect monitoring of fecal indicator bacteria. They do not include data related to testing for harmful heavy metals and other toxins that made their way to L.A.-area beaches following the Palisades and Altadena wildfires in January.

What’s the difference between the annual and weekly report cards?

Weekly grades for beaches and freshwater sites monitored by Heal the Bay are available on the Beach Report Card (beachreportcard.org) and River Report Card (healthebay.org/riverreportcard) websites. These weekly grades are based on the most recent samples, offering a snapshot of bacteria levels to help people gauge their real-time risk.

The annual reports examine patterns and trends over longer periods to identify consistent problem spots, sources of pollution, and ongoing impacts. These findings help policymakers formulate solutions, aid scientists in improving testing and monitoring methods, and give the public a look at which waters are best avoided throughout the year.

On June 20, 2025, the Blue Ribbon Commission on Climate Action and Fire Safe Recovery released a final report recommending ways to create a resilient and sustainable recovery from the 2025 LA wildfires and ensure Greater LA is better prepared for future climate disasters.

Heal the Bay’s CEO, Tracy Quinn, co-chaired on the Commission’s Water Working Group, leading the effort to design critical water protection and reliability measures that will curb climate-related water impacts and pollution and increase fire resilience in high risk communities. This includes solutions focusing on the protection of waterways and infrastructure from climate pollution, the implementation of robust water safety testing plans, the creation of climate-resilient water infrastructure, and the ways to ensure firefighters have the water they need.

The next step will be working with decision-makers at the local, state, and federal levels to implement these solutions. Details below.

 

  The independent Blue Ribbon Commission on Climate Action and Fire Safe Recovery released a final report today outlining ways to ensure a resilient and sustainable recovery from the devastating 2025 LA wildfires and make the region better prepared for future climate disasters. The report assesses a range of recovery and preparation issues, providing important recommendations for efficient and climate-smart rebuilding, equitable recovery, and climate-resilient infrastructure. 

Water safety and resilience is also a key focus of the report. Heal the Bay CEO, Tracy Quinn, served as a co-chair on the Commission’s Water Working Group, driving forward the development of critical water protection and reliability measures in the face of increased climate-related water impacts and pollution. 

“Like so many, these fires forced me to learn firsthand about the recovery, remediation, and preparedness steps we, as individuals, need to take to better protect our homes and families from the impact of climate change,” said Tracy Quinn, CEO of Heal the Bay. “This report provides a broader community-wide lens, seeking to improve our building standards, address our infrastructure needs, and provide equitable funding approaches for recovery and resilience.”

“It also takes a look at how to preserve our most precious resource: water,” Quinn continued. “We need our water resources to be readily available during any crisis and we need the ability to deliver it. We need our waterways and water reserves to be protected against disaster-related toxic contamination. We need to have the tools in place to comprehensively test water safety before we drink or recreate in it after a disaster strikes. And we need to ensure our wastewater systems are built to withstand disaster – and not become part of the problem. This report outlines essential steps we need to take to keep our most precious resource abundant and safe from climate harm.”

Some of the key water quality and safety recommendations found in the report include:

  • Protecting Waterways and Infrastructure from Climate-Related Pollution
    • Implement erosion control measures and nature-based solutions to safeguard watersheds and water infrastructure from post-disaster sedimentation, runoff, and debris flows.
    • Establish buffer zones to help protect communities, reducing potential for secondary harm to waterways.
  • Implementing Robust Water Safety Testing Plans
    • Update state legislation to require water systems to test for a broad array of contaminants before lifting health notices.
    • Improve and implement communication protocols for post-disaster water testing results.
  • Ensuring Water Infrastructure is Climate-Resilient
    • Conduct comprehensive vulnerability assessments of water and sewer infrastructure.
    • Site new systems outside of high-risk areas.
    • Ensure rebuilding along the Pacific Coast Highway properly assesses wastewater treatment and conveyance alternatives to avoid sewage overflow and leakage into the ocean.
  • Ensuring Water Infrastructure Maintains Pressure for Firefighting
    • Utilize low impact development (LID) stormwater capture strategies to increase water supply redundancy 
    • Upgrade systems to meet modern fire flow requirements. 
    • Test flow rates and system capacity under peak demand and emergency conditions.

Detailed Water Recommendations can be found in the Chapter entitled WATER SYSTEM RESILIENCE AND SAFETY on page 60 of the report.

The Commission was created on February 13, 2025, in the wake of the LA fires, to develop a set of policy recommendations to promote a safe, resilient recovery for Los Angeles. The Commission includes a broad cross-section of volunteer technical experts and professionals from governmental, academic, public interest, and other civic institutions. Implementation is critical to the impact of these recommendations and will require engagement with decision-makers at the local, state, and Federal levels. 



Discover how Heal the Bay and partners are rescuing endangered tidewater gobies and restoring habitats devastated by the Palisades fire.

UPDATE 6/18/2025

On June 17, 2025, after five months of expert care at Heal the Bay Aquarium and the Aquarium of the Pacific, a group of federally endangered northern tidewater gobies were released back into their natural habitat—Topanga Lagoon. These tiny, often-overlooked fish were originally rescued in January after the Palisades Fire devastated their home.

Thanks to a collaborative effort between local aquariums, scientists, and government agencies, these resilient gobies not only survived—they’re now back in the wild, where they play a vital role in maintaining the health and balance of coastal ecosystems.

READ THE FULL PRESS RELEASE

Watch our behind-the-scenes look at the Goby release, the community partnerships that made it possible in including Aquairum of the Pacific (watch their release video), and what this means for the future of endangered species conservation in Southern California.

 

UPDATE 3/26/2025

In the aftermath of the fires, our Aquarium Animal Care Team took in 160 federally endangered Tidewater Gobies that were rescued from contaminated waters in Topanga Creek. We’re just one of two facilities to house them in response to the fires, authorized by US Fish and Wildlife Services. While we await confirmation that they can safely be released back into the wild, our experienced team is providing daily care and supporting any natural breeding that may occur, as spring is their peak spawning season. These efforts will continue to support the survival of this vital species.
On March 6, 2025, the Resource Conservation District of the Santa Monica Mountains found a number of healthy adult gobies in the Topanga Lagoon, generating hope for the revival of this important ecosystem. However, a recent survey of the Topanga Lagoon indicates that the Goby habitat has not yet been sufficiently restored to safely release the gobies. We are optimistic about returning the rescued fish to their natural habitat sometime in May. Even after the return of the gobies, Heal the Bay hopes to continue working with USFW initiatives in supporting this essential endangered species work.

UPDATE 2/10/2025

Humans aren’t the only ones who lost their homes in the horrific Palisades fire. The blazes destroyed acres of habitat for local wildlife. They also created polluted runoff that is now fouling the creeks and ponds where many species live. 

That’s why the Heal the Bay Aquarium has taken in around 160 tidewater gobies, a local endangered species of fish living in Topanga’s brackish waters. Now that they have been collected from impacted waterways, these small creatures will receive special care from our highly experienced animal care staff for the next several months.  

Heal the Bay is supporting the rescue in collaboration with the US Fish and Wildlife Service, the Resource Conservation District of the Santa Monica Mountains, Aquarium of the Pacific, and Dr. Brenton Spies, a researcher from the University of the Channel Islands and former aquarist at Heal the Bay. Spies has a long history with these unique little fish. This collaborative effort is not just about saving a species — it’s a hopeful step in preserving the entire ecosystem after the devastating fires.  

Gobies are endangered but amazing 

The tidewater goby, Eucyclogobius newberryi, is a federally endangered species. It is a tiny bottom-dwelling fish that lives in the marshes, lagoons, creeks, and estuaries of California.  It feeds mainly on super tiny animals, like mysid shrimp, amphipods, and aquatic insect larvae. Gobies serve as an important food source for many shore birds, the southern steelhead trout and the all-important California halibut.  

These endangered fish are definitely cute (only about two inches long), but they’re also pretty tough. Tidewater gobies can endure extreme water salinities ranging from 0-42 ppt. They can also survive massive temperature changes, sometimes enduring jumps from 46 to 87 degrees. They even thrive in natural pools with super-low oxygen levels. 

As resilient as these tiny fish are, they’ve been severely impacted by coastal development, the degradation of habitat, and the alteration of naturally occurring water flows. Few other fish species can survive the variable conditions of lagoons, so tidewater gobies have few native predators or competitors but have suffered significant losses from invasive species introduced to their regions.   

Caring for gobies at Heal the Bay  

The endangered gobies are currently housed in two isolated systems at the Aquarium. We have separated them by size and supplied them each with PVC pipe so they can create their own dwellings and live comfortably during their time with us. They consume live plankton, known as brine shrimp. They’ve been eating readily, which indicates they are adjusting well to a new environment.   

The gobies aren’t on public display yet, but we’re working on a dedicated exhibit to showcase them. In the meantime, we’re giving them the space to settle in and adjust to our presence. We can’t wait to share them with visitors once they’re ready.

As part of our partnership with Santa Monica College, we aim to introduce students in the Sustainable Aquaculture Certification Program to the gobies. The goal of this initiative is to show how conservation aquaculture can help support endangered species. Stay tuned for the public unveiling!

In the aftermath of the Los Angeles megafires, there is an increased risk of dangerous debris and pollutants reaching the Santa Monica Bay and its shoreline. Heal the Bay has been monitoring all incoming water quality data from the Los Angeles Regional Water Quality Control Board to determine any potential impact on human health. 

UPDATE – NEW DATA COLLECTED ON MAY 1, 2025 – Results are consistent with previous sampling efforts (i.e. no exceedances of risk screening levels). Get the full update below.

What You Need to Know:

  • There are no existing guidelines to determine human health risk from swimming or surfing in the ocean after an urban fire. This makes it challenging to determine risk to public health from contaminants entering the bay from the burn areas. Heal the Bay used the EPA Risk Screening Tool to evaluate risks to public health. 
    • Recent water testing does not reveal any urgent, lethal threats. Data appears to be below the calculated risk-thresholds for human health.
    • Acquiring missing data is key to ensuring safety. Previous data did not include testing for specific — and particularly concerning — types of arsenic and chromium: Inorganic Arsenic or Hexavalent Chromium (also known at Chromium-6), both of which can be harmful in lower concentrations.
    • UPDATE: Hexavalent Chromium was included in the more recent testing, but Inorganic Arsenic was not. More details below. 
  • Key Findings:
    • Arsenic: All samples were analyzed for Total Arsenic, which is a combination of Organic Arsenic and Inorganic Arsenic. 
      • Inorganic Arsenic is highly toxic but health impacts are most common with exposure from drinking water or contaminated foods.
      • Total Arsenic levels exceed the median background (i.e. pre-existing) concentration (1.490 µg/L), suggesting elevated levels potentially resulting from the fire.
      • UPDATE: Inorganic Arsenic was not included in the latest round of sampling by the LA Regional Water Board. Since our last post, we have been meeting with a group of toxicologists and public health experts. These toxicology experts do not believe testing for inorganic arsenic is warranted because inorganic arsenic is primarily hazardous when ingested; dermal contact is not considered a significant route of exposure under typical environmental conditions.
      • Heal the Bay continues to advocate for testing of inorganic arsenic. It will provide a more in-depth understanding of risk, and can also provide peace of mind for beach visitors. 
    • Chromium: The Los Angeles Regional Water Quality Control Board analyzed for Total Chromium, which includes Trivalent Chromium (an essential nutrient with no known health risks) and Hexavalent Chromium. While there is no human health risk threshold for Total Chromium, the risk threshold for Hexavalent Chromium is 0.1 µg/L.
      • Hexavalent Chromium, also known as Chromium 6, is usually produced by an industrial process, such as hardening alloy steel, and is known to cause cancer and can target the respiratory system, kidneys, liver, skin, and eyes. 
      • Until now, water samples have only been tested for Total Chromium. Although Hexavalent Chromium was not specifically analyzed during that time, results consistently showed Not Detected (ND) for Total Chromium. However, the detection limit for Total Chromium was approximately 16 µg/L, while the median background concentration was only 0.37 µg/L. Thus, even if Hexavalent Chromium were present at harmful levels, it would go undetected. 
      • In the May 1st samples, Hexavalent Chromium was tested for the first time, and results were reported as “Not Detected (ND)”. However, these results are inconclusive because the detection limit was not provided and the Reporting Limits were higher than the human health risk threshold for Hexavalent Chromium which is 0.1 µg/L. Without knowing how low the analytical method can detect, we cannot determine whether Hexavalent Chromium is below the risk threshold.
      • While we don’t have any information that would point to the likelihood of chromium in our coastal waters, Heal the Bay urges caution and recommends retesting all locations for Hexavalent Chromium using methods with detection limits below the risk threshold of 0.1 µg/L. Future testing should ensure methods are sensitive enough to detect concentrations below the human health risk threshold.
    • Heal the Bay is planning to collect sand and water samples from three beaches with stormdrain outfalls, including Rustic Creek Outfall. We are reaching out to labs and will plan to include inorganic arsenic and hexavalent chromium.

What’s Next?  

  • More Water Testing. Heal the Bay plans to conduct additional water quality testing and will provide updates when that data is available. Stay tuned.
  • Recommendations for new public health risk-thresholds for water contamination from climate disasters. Heal the Bay is part of the Southern California Coastal Water Research Project Task Force, which is developing new guidelines for fire-related water quality monitoring efforts.

Keeping Yourself and Your Families Safe

  • Health risk appears to be low for people swimming and surfing in Santa Monica Bay, based on comparisons to risk-thresholds calculated using EPA’s risk-screening level calculator, and the currently available data.
  • Because we don’t have data on Inorganic Arsenic and debris removal is actively occurring along PCH, which can impact air quality and send debris into the water, we are advising the following precautions for the time being:
      • Avoid swimming and surfing within 250-yards of active debris removal. While the US Army Corp of Engineers (USACE) completed their debris removal in May, some properties opted out of this program and active debris removal by private contractors may still be occurring on properties between Carbon Beach and Topanga Creek. 
      • Don’t enter the water for at least 72-hours after a rain event. 
      • Keep an eye out for debris in the water.
      • Risk tolerance is a very personal decision, we are providing data to help inform your decisions. 
      • Bacteria, unrelated to the fires, can still make people sick. Please check our Beach Report Card (or download our app on your iPhone or Android) for the latest bacteria data at your favorite West Coast beach.

In the aftermath of the Los Angeles megafires, there is an increased risk of dangerous debris and pollutants reaching the Santa Monica Bay and its shoreline. Heal the Bay has been monitoring all incoming data on beach sand – specifically from the Los Angeles Regional Water Quality Control Board and the California Coastal Alliance – to determine any potential impact on human health. 

UPDATE – NEW DATA COLLECTED ON APRIL 29 and 30, 2025. Results are consistent with previous sampling efforts (i.e. no exceedances of risk screening levels) and this round includes new tests for Hexavalent Chromium. Get the full update below!

What you need to know:

    • We lack established guidelines for health risks from contaminated sand. There are no existing human health limits to determine risk from recreating on sand, making it challenging to assess the risk that a day on the beach may have on your health. However, using EPA analytical tools, Heal the Bay has evaluated the most recent sand data from across Santa Monica Bay to provide the public with the best assessment available of current health risk.
    • Testing of sand does not reveal any urgent, lethal threats. All available data, which includes testing from a variety of heavy metals, including mercury, barium, chromium, arsenic, and lead, appears to be below the risk-thresholds for human health.
    • Acquiring missing data is key to ensuring safety. Previous data did not include testing for specific — and particularly concerning — types of arsenic and chromium: Inorganic Arsenic or Hexavalent Chromium (also known at Chromium-6), both of which can be harmful in lower concentrations. 
      • UPDATE – sampling conducted on April 29 and April 30 included Hexavalent Chromium. Results discussed below. The Regional Board did not test for Inorganic Arsenic, also discussed below. 
  • Chromium: The Los Angeles Regional Water Quality Control Board samples were analyzed for Total Chromium, which is a combination of Trivalent Chromium (an essential nutrient and not a health risk) and Hexavalent Chromium. 
    • Hexavalent Chromium, also known as Chromium 6, is usually produced by an industrial process, such as hardening alloy steel, and is known to cause cancer and can target the respiratory system, kidneys, liver, skin, and eyes. 
    • While there is no existing human health risk-threshold for Total Chromium concentrations, the levels for Total Chromium were found to be significantly above the human health limit for Hexavalent Chromium of 0.1 ug/L, which is the reason we recommended additional testing for Hexavalent Chromium.  
    • In the April 29/30 samples, all test results for Hexavalent Chromium were Not Detected (ND), which is great news. Heal the Bay is recommending that two locations, Surfrider in Malibu and Rustic Creek Outfall, be tested again because the method detection limits applied to samples from those locations exceeded the risk screening level, so the “Not Detected” result does not definitively show that Hexavalent Chromium concentrations are below the risk screening level. Out of an abundance of caution, additional samples should be analyzed for these two locations.
  • Arsenic: The Los Angeles Regional Water Quality Control Board samples were analyzed for Total Arsenic, which is a combination of Organic Arsenic and Inorganic Arsenic. 
    • Inorganic Arsenic is highly toxic but health impacts are most common with exposure from drinking water or contaminated foods. We are investigating the potential health impacts from being exposed while playing in sand.
    • Total Arsenic concentrations were generally within background levels, meaning levels previously found in the environment before a potential new contamination. We suspect that is because organic arsenic naturally occurs in local soils. However, these levels were above the risk threshold for Inorganic Arsenic. We therefore need to understand the specific levels of Inorganic Arsenic to ensure safety.
    • Rustic Creek Outfall – Total Arsenic here was at least three times higher than at other burned-area beaches, but still within the upper background limit (12 mg/kg). Therefore, this location requires specific caution and should be avoided until further testing confirms its safety.
    • UPDATE: Inorganic Arsenic was not included in the latest round of sampling by the LA Regional Water Board. Since our last post, we have been meeting with a group of toxicologists and public health experts. These toxicology experts do not believe testing for inorganic arsenic is warranted because total arsenic levels are within background levels and inorganic arsenic is primarily hazardous when ingested; dermal contact is not considered a significant route of exposure under typical environmental conditions.
    • Heal the Bay continues to advocate for testing of inorganic arsenic. It will provide a more in depth understanding of risk, and can also provide peace of mind for beach visitors. Heal the Bay is looking into adding inorganic arsenic into our summer sampling events

What’s Next?  

  • Additional Specific Testing for Inorganic Arsenic and Hexavalent Chromium. These findings do not necessarily suggest an immediate public health threat. But they do make clear that we need more testing of the sand, including dedicated testing for Inorganic Arsenic and Hexavalent Chromium to ensure the public has an accurate assessment of risk.
    • Heal the Bay is planning to collect sand and water samples from three beaches with stormdrain outfalls, including Rustic Creek Outfall. We are reaching out to labs and will plan to include inorganic arsenic and hexavalent chromium.
  • Recommendations for new public health risk-thresholds for sand contamination from climate disasters. Heal the Bay is part of the Southern California Coastal Water Research Project Task Force, which is developing new guidelines for fire-related water quality and sand monitoring efforts. We expect these new guidelines will be released by the end of June.

Keeping Yourself and Your Families Safe

  • Based on the assessment of currently available data, it appears that the health risk from recreational contact with sand was low at the time of sampling across beaches along Santa Monica Bay. It’s unlikely that contaminant levels have increased since sampling was conducted, but additional testing will help to confirm and provide assurances to beachgoers.
  • Given that we do not have specific data on Inorganic Arsenic and Hexavalent Chromium, and physical debris hazards have been observed near burned properties along PCH and near stormdrain outfalls that drain areas within the burn area, we are advising the following precautions for the time being:
      • Avoid beaches within the burn area and within 100-yards of Rustic Canyon Outfall at Will Rogers Beach (near Chautauqua Blvd.) in Santa Monica.

      • Parents and pet-owners should take extra precautions and ensure children and pets aren’t consuming sand. 
      • Consider wearing shoes if walking in the wet sand or near a stormdrain outfall.
      • If you see debris that clearly came from a burned structure, do not touch it with your bare hands. 
      • You may also consider rinsing off after returning home from the beach. 
  • Risk tolerance is a very personal decision, we are providing data to help inform your decisions. 

How we assessed potential risk:

  • Heal the Bay used Department of Toxic Substances Control Toxicity Criteria for Human Health Risk Assessments, Screening Levels, and Remediation Goals and the EPA Risk-Screening Level Calculator to determine health risk from recreating on sand. 
  • We evaluated sand quality data from the Los Angeles Regional Water Quality Control Board collected between February 25th and 27th. The data is available here.
    • The LA Regional Board samples were collected from sand/sediment areas that appeared to be the most polluted, including darker “char” in the wet sand and stormwater outfalls.

    • The LA Regional Board tested for contaminants they determined could potentially be present after an urban fire. 
    • The LA Regional Board will be collecting a second round of samples in May 2025.
  • We also evaluated sand quality data collected by the CA Coastal Alliance from after the fires through February 14, 2025, which was consistent with the LA Regional Board’s data.

Getting a water-smart recreation area built in marginalized South L.A. was no walk in the park. But Heal the Bay persevered.

Seventeen years ago, residents of South L.A. began working toward a vision: to transform a long-overlooked lot into a vibrant community space. Heal the Bay’s Meredith McCarthy joined that effort as a committed partner, supporting the neighborhood’s leadership and helping to navigate the challenges of funding, permitting, and environmental planning. Together, they turned a neglected space into a thriving public park rooted in community vision and care.This June, Inell Woods Park officially opens—named in honor of a beloved local activist. The quarter-acre, multi-benefit park is designed to improve the quality of life for historically marginalized residents while enhancing the health of the surrounding watershed. Meredith’s persistence, creativity, and patience made this park a reality, despite major hurdles with funding, permitting, construction, and a global pandemic.

Read the full breakdown from Meredith on the story behind her, Heal the Bay, and the community’s shared labor of love, and how this space can serve as a model of hope and smart environmental planning across greater L.A.

So, how did Heal the Bay get involved in building a park in inland L.A.? 

In 2008, Heal the Bay was working deep inside Compton Creek watershed, the last major tributary to enter the Los Angeles River before it enters the Pacific Ocean. We understood that the health of our rivers and coastal ocean cannot be separated from the health of our inland neighborhoods. We were committed to showing the interconnection of communities, green space, and public health, particularly in under-resourced neighborhoods.  Our goal was to invest in areas where parks were most needed – in historically marginalized areas lacking green space, shade, and clean waterways. Through our community work, we identified a site in South L.A. that could potentially serve as a pilot for our Healthy Neighborhoods, Healthy Environments Initiative. The idea was fairly simple: build a small multi-benefit park that could achieve two goals simultaneously: make life better for residents while improving water quality in the watershed. Getting it done would prove to be much more complex. But we did it.

Tell us about the site before it was a park?

The park sits on what once was a vacant half-acre parcel of land at 87th Street and McKinley Place, owned by CalTrans. The site was riddled with broken concrete and asphalt, with only a few spindly trees. On any given day you could find abandoned desks, sofas, appliances and worn-out clothes littering the site. It was basically a trash dump. Not only a safety hazard, the eyesore became a magnet for crime and a symbol of civic neglect.

And what challenges does the surrounding community face?

The lot is surrounded by residential homes and apartments, including a large public housing complex to the southwest called Avalon Gardens. Almost 40% of residents live at or below the poverty level. In the State’s CalEnviroScreen, the neighborhood scored in the highest-impacted ranking of 91-100%. Recognizing the environmental and social challenges the community faces, we partnered with local residents to reimagine and revitalize the long-neglected lot into a space that serves their needs.

What are some of the features of this park? What makes it special for this community and the region as a whole?

The park serves as a green space, fitness area, a meeting spot, an environmental education site, and a water quality improvement project, bringing lasting benefits to a resilient and historically underserved neighborhood in Greater L.A. With exercise stations, a tot lot, shaded seating, biodiverse gardens, and a system that captures and reuses stormwater, the park is a prime example of smart water design—using green infrastructure to support both community well-being and cleaner waterways. It’s a valuable space for play, learning, and connection for kids, teens, and seniors alike. The project creates multiple benefits and distinct open spaces designed for active and passive recreation.  Equally important, it serves as a beacon of hope for the hard-working families that live in a neighborhood that hasn’t received a lot of infrastructure love or funding. 

Why is this project important to Heal the Bay from an overall water quality perspective?

It’s pretty simple: Creating more green space in individual neighborhoods improves water quality throughout all of Los Angeles County’s interconnected watersheds. In addition to providing recreation areas and wildlife habitat, green spaces can function as essential stormwater solutions by capturing and naturally cleansing polluted runoff. These multi-benefit parks improve local water quality, increase water reuse and supply, reduce carbon, and mitigate the heat island effect.

For all the “stormwater wonks” out there, can you explain how the park has been engineered?

The park is designed to capture water when it rains. This prevents polluted runoff from reaching Compton Creek and the Los Angeles River. The stormwater treatment component is the Permavoid system and has been used in several other City of L.A. parks. Permavoid is a multi-functional stormwater management system engineered to create functional and appealing stormwater capture. This system treats stormwater as a resource, rather than a waste product. The captured water will be filtered and used to irrigate the native plants and trees at the park.

How much water can the park capture and reuse?

For LID (low impact development) compliance, the requirement is to capture the 85th percentile storm, which is approximately 1 inch in 24 hours. Based on the design calculations, each storm event of 0.98 inches or more will yield approximately 20,800 gallons of captured runoff for storage in the Permavoid Planter for eventual use. We assume that five or six rain events will meet or exceed the 85th percentile storm in an average year. This would result in approximately 104,000 to 124,000 gallons of rainwater captured for reuse over the rainy season between October and April.

How did the project come together in the beginning?

In 2012 Heal the Bay won an initial $1.3 million grant to design and build the park. But the logistics of remediating an abandoned lot became far more complicated than we had ever imagined. Leasing the land from CalTrans and getting the necessary permits became almost insurmountable, but we stuck to it. Construction costs began to mount, and then the pandemic stalled the park for two years. Councilmember Curren Price Jr., who represents the neighborhood, kept the park on track though. His office helped us secure additional funds from a federal Community Block Grant. Through the efforts of L.A. County Supervisor Holly Mitchell, Accelerate Resilience LA, the Rivers and Mountains Conservancy and the Bonneville Environmental Fund, we finally secured the $3.1 million to get the park built. After years of delays, we started construction on Feb. 12, 2024.

Meredith, what was the hardest part about getting this park built?

The city bureaucracy can be mind-numbing. There isn’t a rule book or an air traffic controller to help navigate the permitting process. If it weren’t for our amazing project manager, Erin Jones, at Griffin Structures, and engineer Barbara Hall, we wouldn’t be here today.

What’s next? Can these types of projects be replicated at scale?

Inell Woods Park is a good example of how the County’s Safe Clean Water Program aims to increase local water supply, improve water quality, and protect public health by focusing efforts on multi-benefit projects in marginalized communities. Multi-benefit projects are the most efficient and effective use of our taxpayer dollars because they are cost-conscious solutions that serve both community and environmental needs.  Heal the Bay has spent decades working on smart infrastructure policies and funding measures like Measure A and W to create community-centered improvements. With commitment, we can build more parks like this throughout our region. It’s critical as climate impacts intensify and imported water supplies become more unreliable and expensive.

Why is this project important to you personally?

Inell Woods is proof that multi-benefit projects work. We can use infrastructure dollars to improve the quality of life and clean up stormwater. We aren’t going to support the environment without involving the people, too.

Who motivated you? Who did you meet along the way?

Over the 10 years it took this project to come together, we watched the neighborhood kids grow up. So many amazing families came out to support and share their hopes and dreams about this space. Jimmie Gray, Inell Woods’ daughter, was a tremendous force of love and action. She became our greatest cheerleader.

There were a couple of people that really stuck with us that made the park possible. Darryl Ford at Parks & Rec, who I really believe is the smartest man in the city, never let us down. Sherilyn Correa and Xavier Clark from CD9 sat through hours of meetings and were always willing to go the extra mile and fight to make this happen. Michael Scaduto from LA Sanitation came in later in the process but was keen on streamlining and finding solutions to our permitting and construction frustrations. The vision of this park, however, really belongs to Kendra Okonkwa at the Wisdom Academy for Young Scientists. She made us believe that change could happen in her neighborhood. Finally, I have to honor my partner through most of this, ex HTB-staffer Delaney Alamillo. Her deep love of community and commitment to “listening first” is tattooed on my heart.
