Heal the Bay issued its 34th annual Beach Report Card today, issuing A-to-F grades to more than 700 beaches along the Pacific Coast based on levels of bacterial pollution in 2023-2024. The lower the grade, the greater the chance of ocean-goers getting sick.
This year’s report is really a story of two seasons – summer and not summer.
The good news is that nearly 90% of monitored California beaches received A or B water-quality grades for the dry-weather summer months. That figure is close to the state’s 10-year summer average, but does mark a 6% drop from our last Report Card.
That means beach lovers had a very good chance of finding a shoreline with safe water quality during the state’s prime ocean recreation period (April-October 2023). To read the entire report and see how your favorite beach fared, please click here.
Southern California beaches (Santa Barbara to San Diego counties) got 90% A or B grades in the summer. NorCal beaches (Del Norte to Marin counties) also earned 90% A or B summer grades, while Central California beaches (San Francisco to San Luis Obispo counties) notched 84% A or B marks.
But surfers and other year-round ocean-goers weren’t as fortunate.
During the dry winter season (Nov. 2023-March 2024), only 66% of the 501 beaches monitored in California received overall A or B grades, well below the state’s 10-year winter average.
Coastal counties in California received 31% more rainfall during the winter reporting period than the 10-year average. The deluge flushed bacteria and other pollutants through storm drains into the ocean and caused numerous sewage spills, which dramatically impacted water quality.
The poor winter grades underscore two of the biggest ongoing beach water-quality challenges for the state: worsening climate change and crumbling infrastructure.
More frequent and more severe storms will only exacerbate the urban runoff that pollutes our sea. It’s critical that the state and municipalities invest in more stormwater capture projects that will cleanse, hold and reuse water rather than sending polluted runoff to the sea. It’s a double-win for our drought-challenged state.
Separately, the state is seeing an uptick in sewage spills thanks to overtaxed sanitation systems during storms and to outdated sewer systems that are breaking down because of age or inadequate upkeep. Heal the Bay supports reasonable ratepayer increases to help sanitation agencies keep up with inflation and our new climate reality.
Here’s a ranking of the 10 most polluted beaches in Summer Dry Weather along the West coast in 2023-24:
1. Tijuana River Mouth (San Diego County)
2. Playa Blanca (Baja, Mexico)
3. Santa Monica Pier (Los Angeles County)
4. Tijuana Slough (San Diego County)
5. Linda Mar Beach (San Mateo County)
6. Lakeshore Park (San Mateo County)
7. Imperial Beach at Seacoast Drive (San Diego County)
8. Border Field State Park (San Diego County)
9. Marina del Rey Mother’s Beach (Los Angeles County)
10. El Faro (Baja, Mexico)
The Beach Bummers in San Diego County and Baja all suffer from persistent sewage issues. The Tijuana River annually discharges tens of millions of gallons of untreated sewage into the ocean, originating from inadequate sanitation infrastructure in Tijuana.
Enhancements are underway, including the U.S. EPA-funded upgrades to the Punta Bandera treatment plant and the South Bay International Wastewater Treatment Plan. Heal the Bay advises against swimming at these beaches until the upgrades are completed, which may take a decade or more.
The City of Santa Monica has wrestled for years with poor water quality at the Pier, which is plagued with droppings from roosting birds and urban runoff. The enclosed Mother’s Beach in Los Angeles County might attract families because of its placid waters, but very poor circulation has led to chronic bacterial exceedances. Families beware.
In San Mateo County, Linda Mar Beach has been impacted by pollution primarily through San Pedro Creek, which channels urban runoff directly to the ocean. Lakeshore Park, located within a network of stagnant water channels in San Francisco Bay, suffers from poor circulation and chronically impaired water quality.
On a more positive note, 12 California beaches made Heal the Bay’s Honor Roll in this year’s report, meaning they earned perfect A+ grades every week in all summer and winter reporting periods. While that’s reason to celebrate, that total is a notable decrease from the 30-50 sites typically named as Honor Roll beaches in past reports. The very wet winter caused many past honorees to suffer from bacterial exceedances.
Steps you can take to stay healthy at the beach:
• Visit beachreportcard.org for weekly grades
• Avoid shallow, enclosed beaches with poor water circulation.
• Swim at least 100 yards away from flowing storm drains, creeks, and piers.
• Stay out of the water for at least 72 hours after a rain event
Daily Beach Water Quality Predictions Are Now Online
For the tenth straight summer, Heal the Bay is posting daily water quality predictions for California beaches on our Beach Report Card with NowCast . To make these predictions, we use computer models that examine correlations between environmental conditions (such as temperature, rain, and tide) and historical bacteria concentrations. Our NowCast models then predict with high accuracy how much bacteria could be present in the water given the current local conditions at the beach.

A day at the beach should not make anyone sick. That’s why health officials across the state monitor water quality at the beach every week during the summer. When officials detect high levels of bacteria, they issue a public health advisory. However, by the time traditional water quality samples are processed, a minimum of 18-24 hours have passed, making the information outdated. With samples taken only once every 7 days, a weekly water quality grade may not provide the most useful or updated information since water quality can fluctuate rapidly. Heal the Bay believes that we need daily water quality information to better protect public health – our NowCast program does exactly that, issuing daily water quality information for 14 beaches this summer.
NowCast predictions appear on the Beach Report Card website and app with the symbols below. A Blue “W+” symbol indicates a low risk of illness from water contact, while a Red “W-” symbol indicates a high risk of illness.

You may notice we do not have as many beaches in NowCast this year as we have had in previous years . This is due to the decline in accuracy with our current linear models, which struggle to keep up with the increasing weather anomalies, changing environmental conditions, and unusual bacterial data patterns we’ve seen in recent years. Consequently, we did not provide NowCast predictions for this past winter. Heal the Bay is in the process of reconstructing our environmental and bacteria database and we plan to develop new and improved prediction models this year. We hope to secure the necessary funding to enhance our model’s accuracy and provide more precise predictions for more beaches in the future.

Don’t see your beach on the map? Let us know if you have a beach we should consider for NowCast — we are continually refining and expanding this program and hope to cover more beaches in the future. Predicting water quality is complex and we want to make sure we get it right. This means we need access to a myriad of data sources to make accurate predictions, and when data are not readily available, we can’t make the prediction.
Communities looking to bring daily water quality predictions to their favorite beach spots can advocate for this cause in the following ways:
If you can’t find NowCast predictions in your area, you can see the latest water quality grades issued to over 500 beaches on the Beach Report Card Website. In the meantime, we are working to improve and expand the NowCast system, so check back to see if your favorite beach has water quality predictions.

This is a developing story and we will update information as new details come to light.
The City of LA/LA Sanitation & Environment has responded to the April 7 deadline from the Regional Water Board and did not accept the fine or waive the hearing. They have instead entered into further negotiations with the Regional Water Board. More to come as we receive information.
Late last week, the Los Angeles Regional Water Quality Control Board announced a tentative fine of $21.7M to the City of LA for the July 2021 sewage spill at the Hyperion Treatment facility. The fine is based on five categories of violations, including 1) the discharge of 12.5 million gallons of raw sewage to the Santa Monica Bay, 2) failure to perform offshore sampling for 14 days, 3) failure to comply with permit requirements for odors for 80 days, 4) failure to comply with monitoring and permit reporting requirements for 108 days, and 5) violations of water quality limits for 217 days (38 serious and 22 non-serious violations). The City of LA has until tomorrow, April 7, to agree to this fine and waive a hearing on the matter or to request a postponement of the hearing to allow for further deliberations. Even if the City agrees, there will be a 30-day window for public comment. If the City does not agree to the settlement or ask for a postponement, there will be a hearing. While the maximum amount for the fine, based on the violations , could have been over $500B (yes, that’s billion!), $21.7M is actually the largest penalty the LA Regional Water Board has ever proposed for permit violations. We don’t yet know how or where the final fine amount will be allocated but we hope that a majority of it will go to Supplemental Environmental Projects (SEPs), which provide environmental and public health benefits to affected areas and communities. The good news is that LA Sanitation & Environment (LASAN) has taken numerous steps to en sure this doesn’t happen again by implementing recommendations from an Ad Hoc Advisory Committee of water quality experts from across the country, as detailed in their r eport that was released in February 2022. Namely, LASAN has installed additional alarms (audio and visual), completed a comprehensive update of protocols for emergency response a nd notifications, implemented an interagency task force for emergency response actions with LA County, El Segundo and City of LA departments, established a hotline call-in number operated 24/7, conducted equipment tests and procedure practices, installed new equipment , and upgraded existing equipment . Additional improvements that are in-progress or planned include equipment upgrades, development of plans to protect major equipment from flood damage, and more. Heal the Bay will continue to advocate to ensure that the City of LA provides sufficient funding to LASAN for critical upgrades and ongoing operations and maintenance. We will continue to track this issue and provide updates as we get them as well as opportunities for the public to weigh in.
According to a new Daily Breeze article, “42 million gallons of sewage entered LA waterways in past 15 years. More than half of the total was spilled in 2021 alone. A nearly catastrophic disaster at the Hyperion Water Reclamation Plant and the sudden collapse of a sewer system in Carson last year combined to make it the worst since the beginning of the data set in April 2007. The two spills, roughly six months and 15 miles apart, led to the total release of 25 million gallons of raw sewage either directly into the ocean or into waterways that empty into it.”
It’s been nearly 8 months since the massive sewage spill from the Hyperion Treatment Plant and two key updates occurred recently.
First, we recently learned that Hyperion Treatment Plant has not been complying with air quality standards since the spill. This is alarming news considering that the plant emits greenhouse gasses hundreds of times more potent than carbon dioxide. While Hyperion is no longer discharging under-treated sewage into the ocean, the environmental impact of the sewage spill continues. We urge regulators to take prompt action and ensure Hyperion’s air emissions are in compliance.
Second, The City of Los Angeles, Board of Public Works assembled an advisory committee composed of government officials, academics, and NGO representatives. Our very own CEO, Shelley Luce, was on the committee. The committee was tasked with conducting an independent assessment of the spill, and their findings were recently released in February in a report along with recommendations for minimizing sewage spill risk in the future.
The report found that a series of missteps led to the sewage spill rather than a single sudden influx of debris that inundated Hyperion’s machinery, which was the original theory. Here is the series of events as we understand them:
The report recommended the following improvements and next steps:
We appreciate the creation of this report and we support its recommendations for improvements to Hyperion’s systems and processes. Heal the Bay’s additional recommendations for next steps in light of the report are:
Heal the Bay is committed to working with LA City Public Works and Sanitation (as well as other agencies and groups) to make sure that the report recommendations are addressed promptly to protect the health and safety of Hyperion’s workers as well as the general public and the environment. Implementation of the recommendations along with the rebuilding of public trust will be paramount as Hyperion transitions to full wastewater recycling by 2035 . This transition means that Hyperion will no longer discharge treated water to the ocean, but will instead recycle 100% of its water to provide for a reliable and local source of water in the face of ongoing drought and climate change impacts. Heal the Bay is a strong supporter of this effort to reduce our reliance on imported water as well as reduce impacts to the ocean – we will be tracking the issue closely to ensure that public health is prioritized along with sustainability.
We have some promising news regarding the Hyperion Treatment Plant. For the past few months, the plant has been operating in a diminished capacity due to the damage it sustained on July 11 that resulted in the discharge of 17 million gallons of raw sewage nearshore (1 mile out) . Consequently, LA Sanitation (LASAN) was discharging wastewater from Hyperion Treatment Plant into the ocean (5 miles out) that did not meet regulatory requirements. We now have confirmation that the plant is fully operational according to the Los Angeles Regional Water Quality Control Board (LARWQCB ) .
After the July 11 disaster, LASAN was issued a notice of violation by the LARWQCB for the discharge of raw sewage in violation of their permit, which will likely result in fines. Further, LASAN was required to conduct additional water quality monitoring by the LARWQCB, initially consisting of daily samples taken at multiple locations and depths , 5 miles offshore. In mid-September the LARWQCB approved a request by LASAN to reduce monitoring to three times per week and , just this week , approved LASAN’s request to cease all additional offshore monitoring. The LARWQB made this decision based on the water quality data and the reports that LASAN has been required to submit. We have also reviewed the data provided on Hyperion’s recovery webpage and found that contaminant levels in the wastewater discharged into the ocean do indee d meet regulatory requirements. However, we do have a few lingering concerns about individual events of water quality exceedances over the last month, as well as remaining maintenance work to be done.
We are relieved that Hyperion now appears able to properly treat wastewater before it is discharged into the ocean. However, we still do not know the cause of the flooding and subsequent sewage spill . Heal the Bay is part of an ad hoc group meeting to discuss the causes of the incident and the response by government agencies, and to make recommendations for improvement. The group meets nearly every week with the aim of producing a comprehensive report by the end of the year. Heal the Bay will continue to push for answers from LASAN because we must make sure events like this do not happen in the future. We also look forward to carefully reviewing the report that LASAN must submit to the LARWQB by November 8 as well as tracking and ensuring that there is enforcement of the violations.
LA Sanitation recently released a report with an in-depth description of the events that led to the sewage discharge into the Santa Monica Bay on July 11 & 12. Here is a summary of what we learned.
The discharge occurred because the Hyperion Plant’s barscreens (trash filtration devices) clogged leading to a catastrophic flood event at the facility. Raw sewage flooded large swathes of the facility and damaged machinery and infrastructure necessary for the plant to function. Millions of gallons of this sewage were released through the 1-mile outfall and into Santa Monica Bay as an emergency measure to prevent further flooding and the plant going offline completely.
So far, no one has been able to determine the origin of the large amount of debris that clogged the barscreens that day. The flooding also made it impossible for Hyperion to determine the amount of debris that caused the blockages. These are two critical pieces of information for the incident investigation, and we are keeping up the pressure for some answers soon. Fortunately, the minute-by-minute account of July 11 & 12 in Hyperion’s report gives us some clues as to what went wrong that day and how events like this can be prevented in the future:
We appreciate the transparency and data that Hyperion has provided in their report and on their website . Nevertheless, there are still some big questions that need to be answered in addition to the origin of the barscreen debris. Hyperion has not made an official announcement that they are fully operational, and we would appreciate a timeline of when they expect that to happen. The Hyperion Recovery website is still listing some critical process equipment as currently being serviced, and there are reports that the treatment plant is almost fully operational. We are also seeking more information on the quality of the wastewater currently being discharged out the 5-mile outfall.
What was causing the foul odors near Hyperion? We are getting this question a lot, so we wanted to provide some more detail. Flooding at the plant damaged the pumps that move sewage from open-air holding tanks to the secondary processing infrastructure. For three weeks, excessive amounts of sewage built up in the holding tanks while workers repaired the pumps. The odors that have plagued South Bay communities came from these holding tanks. Hyperion stated that they have been processing this backlog of sewage, and air quality will continue to improve. We’ve also learned that Hyperion has ended the air filtration & AC unit reimbursement program for households impacted by the odors.
Here is what has been going on behind-the-scenes at Heal the Bay as a follow up to the massive sewage spill from the Hyperion plant back in July 2021.
We took a tour of the Hyperion plant to see the extent of damages from the incident, which is still under investigation. We learned about what’s happening to recover Hyperion as efficiently and safely as possible, and we met some of the hardworking people who have the enormous responsibility to treat LA’s wastewater day in and day out. We are working closely with LA Public Works to evaluate existing systems for repairs and upgrades at the plant where needed.
Recent data from the Hyperion 2021 Recovery website shows the effluent coming out of the 5-mile pipe from Hyperion is getting back to within regulatory limits for most water quality measurements. However, bacteria levels at the 5-mile outfall are consistently exceeding health limits, which is alarming. The public has not been provided with a timeline for when water quality improvements are expected. Fortunately, bacteria does not appear to be impacting our beaches – as indicated by beach water quality monitoring. According to the Clean Water Act, Hyperion should be fined for every day it is out of compliance with public health and safety standards. So far it has been 74 days since the spill first occurred.
An engineer points to how high the flooding water was during the catastrophic incident at the Hyperion plant on July 11-12.
When the spill occurred on July 11-12, there was catastrophic flooding within the Hyperion plant. Raw sewage permanently disabled plant electronics that control pumps and other functions at the plant, and equipment had to be replaced. For many weeks the plant could not complete the secondary phase of the treatment process, and the only option was to pump under-treated wastewater into the ocean. The replacement and repairs are mainly done and water quality is mostly back to normal. The elevated bacteria levels at the 5-mile outfall are still an issue and we are pushing the City to determine the cause and fix it as soon as possible.
The City of Los Angeles Sanitation and Environment Department (LASAN) submitted their 30-day action report to the Regional Board and US EPA, and we are reviewing it. We’ll provide an in-depth update about it soon. Recently at the request of LASAN, the Regional Water Board reduced the required sampling from daily to three times per week.
Our team continues to closely monitor water quality with the Beach Report Card and LA County’s Beach Water Quality Advisories website . The good news is, aside from the usual bummers, we’re seeing good grades at most of LA’s beaches for the past month. A couple sites with chronic water quality issues are the Santa Monica Pier and Mother’s Beach in Marina del Rey — coming into contact with the water at these beach areas should generally be avoided, especially by young children, senior citizens, and people who are immunocompromised. Install our free Beach Report Card iOS or Android app so you can have the latest water quality grades in your pocket.
