Radioactive pollution still haunts Hunters Point in San Francisco

Last week, residents were informed by the San Francisco Department of Health that a test taken in November 2024 at the former site of Hunters Point Naval Shipyard showed radiation levels of airborne Plutonium 239 had exceeded the Navy's "action level."

San Francisco — More than a half century after the U.S. ignited 67 atomic weapons in the the central Pacific Ocean, a former Navy base in the Bay Area continues to carry that nuclear legacy.Last week, residents were informed by the San Francisco Department of Health that a test taken in November 2024 at the former site of Hunters Point Naval Shipyard showed radiation levels of airborne Plutonium-239 had exceeded the Navy’s “action level,” requiring the military to further investigate. The city and the residents were not informed until 11 months after that initial reading. Hunters Point, a 500-acre peninsula jutting out into San Francisco Bay, served as a military laboratory to study the effects of nuclear weapons from 1946-69 following World War II. Although the research largely focused on how to decontaminate U.S. warships and equipment targeted with atomic bombs, the experimentation left much of the shipyard laced with radioactive contaminants and toxic chemicals.For the last 30 years, the Navy has sought to clean up the area — now a U.S. Superfund site — with the long-term goal of redeveloping it into new housing and parkland. But some Bay Area community leaders say haphazard remediation work and lackluster public outreach have endangered the health and safety of residents of the Bayview-Hunters Point neighborhood that sits beside the former shipyard. And they point to the Navy’s nearly year-long delay in informing them of the elevated Plutonium-239 reading, taken in November 2024, as just the latest example.Plutonium-239 is a radioactive isotope and byproduct of nuclear bomb explosions. The elevated readings from November 2024 came from a 78-acre tract of land on the northeast portion of the shipyard, known as Parcel C.“The City and County of San Francisco is deeply concerned by both the magnitude of this exceedance and the failure to provide timely notification,” wrote San Francisco Health Officer Susan Philip in an Oct. 30 letter to Navy officials. “Such a delay undermines our ability to safeguard public health and maintain transparency. Immediate notification is a regulatory requirement and is critical for ensuring community trust and safety.”Navy officials and some health experts insist the radiation levels detected at the site, while above the Navy’s action level, did not pose an imminent or substantial threat to public health. Exposure to this level of Plutonium-239 every day for one year would be less than one-tenth the dose of radiation from a chest X-ray, according to a Navy spokesperson. “The San Francisco Department of Public Health’s letter references a single outlier air sample that detected Plutonium-239 above the regulatory action level,” a Navy spokesperson said in a statement to The Times. “Regulatory action levels are deliberately and conservatively established below levels of health concern, and a single detection of Pu-239 at this level does not pose a risk to human health or public safety.”The Navy said it has collected more than 200 ambient air monitoring samples from Parcel C since it began performing fieldwork there in 2023. The November 2024 sample was the only reading with elevated Plutonium-239, the Navy spokesperson told The Times. Plutonium isotopes emit alpha radiation that is relatively benign outside the body, because it cannot travel through solid objects. However, if these radioactive particles are inhaled, they can damage the lungs and increase the long-term risk of developing certain cancers, according to the Centers for Disease Control and Prevention. “What we generally are concerned about for alpha emitters is if you get them into your body, and either through inhalation, ingestion, inadvertent injection — like somebody gets a cut and it gets into their body,” said Kathryn Higley, a professor of nuclear science at Oregon State University. But it’s the lack of transparency and the 11-month delay in reporting the reading that has fomented community mistrust and raised questions regarding the military’s competency to safely clean up the polluted shipyard. In 2000, the EPA admonished naval officials for neglecting to inform residents that a fire had broken out at a hazardous landfill at Hunters Point. In 2017, two employees of the consulting firm Tetra Tech, who were hired by the Navy to assess radiation levels at Hunters Point, pleaded guilty to falsifying data in an effort to avoid having to perform additional cleanup on some areas of the shipyard. The presence of radioactive air contaminants — at any level — compounds the health risks of the Bayview-Hunters Point neighborhood, which already faces high exposure to toxic diesel particles from big rigs traveling on nearby freeways and cargo ships visiting the Port of San Francisco. Hunters Point Biomonitoring Foundation, a local nonprofit, has found concerning levels of toxic substances in urine screenings it has provided to several residents of the neighborhood, especially among older individuals and those living closer to the former Naval shipyard.“Now, you’re talking about adding one of the most devastating radionuclides known to the human cardiopulmonary system to the chemical burden,” said Dr. Ahmisa Porter Sumchai, the foundation’s medical director and principal investigator. “The particulate load is enough to kill people,” Sumchai added. “But you add ... a little Plutonium-239, and it’s a recipe for death.” Philip, the San Francisco health officer, said in a statement that she met with Navy officials Oct. 31 and received assurances that air and dust monitoring is “ongoing” and that the military agency is “reviewing their duct control methods to ensure they are fully protective of public health.”As a result, “no immediate action is required from a public health safety standpoint,” she said, adding that her office will continue to closely monitor the situation.Other experts argued the situation was overblown. Phil Rutherford, a radiological risk expert and corporate consultant, called the delayed notification “unacceptable” but said the San Francisco health department’s letter was “a storm in a teacup” considering the low levels of radioactive material.Higley, the Oregon State professor, said the site’s long history of delays and scandals likely added to backlash from community members. “I understand [residents’] frustration that they want to see this place cleaned up so that they can safely use it,” Higley said. “And there’s been a lot of reasons for why this process takes so long. But, from a radiological perspective, the actual residual radioactivity at the site is pretty modest.”In November 2024, a Navy contractor was grinding asphalt on the site — a construction project that, while unrelated to the site’s historical contamination, triggered the Navy to monitor for any air quality issues. One of its air samplers, in Parcel C — collected 8.16 times 10‐15 picocuries per milliliter of Plutonium-239 — twice the established action level — according to a Navy spokesperson. Navy officials sent the sample to a lab for analysis, and the initial results came back in March 2025, showing high radiation levels. In April, they ordered the lab to reanalyze the sample. In the follow-up analysis, radiation levels of Plutonium-239 were below action levels.Between May and September, the Navy “further investigated the test results and conducted a methodical review of the laboratory’s procedures and practices to ensure they complied with standards,” according to the Navy spokesperson. “A third party also conducted an analysis of the lab’s performance.”Later that September, the Navy told the U.S. Environmental Protection Agency and several California state agencies about the elevated airborne radiation from Plutonium-239, in preparation for an upcoming community meeting. That information later trickled down to the San Francisco health department. At some point, the Navy published some air quality data for Parcel C gathered between October and December 2024 on a website where it curates several environmental monitoring reports. That report only showed the lower Plutonium-239 radiation levels from the reanalysis were below the action level.A Navy spokesperson told The Times that it was “mistakenly uploaded.”“As soon as the Navy realized an incomplete report was uploaded, it was removed from the website,” the spokesperson said, while the Navy worked to verify the results. All that has contributed to the confusion and concern among locals and advocates alike. Navy officials are expected to attend a Hunters Point Shipyard Citizens Advisory Committee Meeting on Nov. 17. When fieldwork is occurring at the shipyard, the Navy monitors for Plutonium-239 and several other radioactive elements that may have resulted from historic fallout from atomic weapons testing. Acquired by the Navy in 1940, Hunters Point was initially a base where ships were built, repaired and maintained during World War II. After the war ended, it became home to the Navy Radiological Defense Laboratory, a military research facility dedicated to investigating the effects of nuclear weapons and radiological safety.The Navy bombarded a fleet of U.S. warships with nuclear weapons as a part of atomic testing in the Marshall Islands. The irradiated vessels were towed to Hunters Point, and used as the material and hardware upon which scientists tested decontamination methods. In 1974, the shipyard was deactivated. Hazardous chemicals and low-level radiological contamination were identified, prompting the U.S. EPA to place the site on its Superfund list in 1989. The Navy has led cleanup efforts, excavating contaminated soil and demolishing buildings. A largely residential parcel of the base, Parcel A, was turned over to San Francisco and has been redeveloped with new town houses and condos. A collective of 300 artists live and work in former naval buildings. But dangers continue to emerge during ongoing remediation work. In recent years, the Navy has recovered radioactive objects, including dials and deck markers coated with paint containing Radium isotopes to provide a glow-in-the-dark effect. Sumchai, medical director of the biomonitoring foundation, said she has observed large stockpiles of contaminated soil held in areas without any protective fencing to prevent contaminants from spreading off site. “I view this as a local public health emergency,” Sumchai said. “I think that everything should be done to contain it and to remove people safely, if necessary, from documented areas of exposure.”But to the casual observer the site looks unremarkable.Hunters Point juts out into the San Francisco Bay just north of where Candlestick Park, the former home of the San Francisco 49ers, used to stand. Beyond the abandoned barracks and drydocks, the site is now mostly an empty expanse of grass and reeds, with an unobstructed view of the bay. The cleanup sites, including Parcel C, are still fenced off, and only those with authorized credentials are allowed onto the property.On a recent weekday afternoon, ravens flew and cawed over the long-vacant shipyard buildings, while construction crews and trucks ferried building equipment up and down Hill Drive — a steep road leading to brand new homes standing sentinel over the former shipyard.And beyond waiting for a new batch of Navy reports, there was no way of knowing what’s in the air.

Check Your City: Air Pollution Linked to Slower Marathon Times

By Deanna Neff HealthDay ReporterTHURSDAY, Nov. 6, 2025 (HealthDay News) — Does the city you run in make a difference? Researchers say yes, it does.When marathon runners hit the wall or fall behind their goal pace, they often blame fatigue, weather or nutrition. However, a study from Brown University published in Sports Medicine suggests a less obvious, environmental culprit: air pollution.Researchers analyzed a dataset of 2.6 million marathon finish times from major U.S. races, including those in Boston, New York City and Los Angeles, spanning 17 years and matched it to estimated pollution levels from weather stations. They found a direct link between slower average finish times and higher concentrations of fine particulate matter known as PM2.5.The data also showed that the fastest runners were more affected by this effect.PM2.5 refers to tiny pollutants smaller than 2.5 micrometers in diameter. These particles are often the focus of air-quality health advisories, because they can travel deep into the lungs and enter the bloodstream, causing inflammation and chest constriction, reports The New York Times.The study revealed a measurable slowdown tied to PM2.5 levels. For every increase of one microgram per cubic meter increase in these tiny particles, the average finish time for runners dropped.In other words, on a day with even moderately elevated pollution, a runner's time could be slower by several minutes.The Los Angeles Marathon generally had the highest estimated median pollution levels and the slowest median finish times among the races studied. While this could owe to other factors like warmer weather and a hillier course, the overall pattern of slower finishes in more polluted races held true across all cities, even when comparing different years within the same marathon city.Boston had the fastest average finish time and one of the cleanest air levels among the cities, along with Minneapolis/St. Paul and New York City.What makes this finding particularly notable is that it affects even the fittest individuals. “What’s notable is that we’re looking at people who are all incredibly healthy,” Joseph Braun, a professor of epidemiology at Brown, told The New York Times. “But even among really healthy people, air pollution is having an important, albeit subtle, effect on your physiology.”Surprisingly, the slowdown was more pronounced for faster-than-average runners. Researchers suspect this may be because elite and competitive marathoners breathe in more air — and do so more rapidly — inhaling a larger dose of the pollution over the 26.2-mile course.PM2.5 primarily comes from the burning of fossil fuels — such as from power plants, gasoline or diesel vehicles — as well as from forest fires and wood burning. While air quality has improved in many U.S. regions, short-term spikes from sources like wildfire smoke have become a growing concern, The Times said.

New Study Links Wildfire Smoke to Premature Births

WEDNESDAY, Nov. 5, 2025 (HealthDay News) — Wildfire smoke may do more than harm the lungs.New research shows it could also raise the risk of premature birth.A large study from the University of Washington found that pregnant people exposed to wildfire smoke were more likely to deliver early.The findings, published Nov. 3 in The Lancet Planetary Health, are based on more than 20,000 births across the United States between 2006 and 2020.About 10% of babies in the U.S. are born early, which can lead to lifelong health problems. While air pollution has already been linked to preterm birth, this is one of the biggest studies so far to look specifically at wildfire smoke as a contributor, researchers said.“Preventing preterm birth really pays off with lasting benefits for future health,” said lead author Allison Sherris, a postdoctoral researcher at the University of Washington in Seattle.“It’s also something of a mystery. We don’t always understand why babies are born preterm, but we know that air pollution contributes to preterm births, and it makes sense that wildfire smoke would as well," she added in a news release. "This study underscores that wildfire smoke is inseparable from maternal and infant health.”Researchers measured how often pregnant people were exposed to wildfire-related fine particle pollution, known as PM2.5, and how much they were exposed.The risk of preterm birth was higher when exposure happened in the second trimester, especially around week 21. Later in pregnancy, the biggest risk came from high levels of wildfire smoke, above 10 micrograms per cubic meter. The strongest link was seen in the Western U.S., where wildfire smoke has become more frequent and intense. “The second trimester is a period of pregnancy with the richest and most intense growth of the placenta, which itself is such an important part of fetal health, growth and development,” said co-author Dr. Catherine Karr, a professor of pediatrics and environmental health."So it may be that the wildfire smoke particles are really interfering with placental health," Karr added in a news release. "Some of them are so tiny that after inhalation they can actually get into the bloodstream and get delivered directly into the placenta or fetus.”Researchers say more work is needed to understand exactly how wildfire smoke affects pregnancy, but the evidence is now strong enough to take action for pregnant people."There’s an opportunity to work with clinicians to provide tools for pregnant people to protect themselves during smoke events," Sherris said. "Public health agencies’ messaging about wildfire smoke could also be tailored to pregnant people and highlight them as a vulnerable group."SOURCE: University of Washington, news release, Nov. 3, 2025Copyright © 2025 HealthDay.

By Dennis Thompson HealthDay ReporterMONDAY, Nov. 3, 2025 (HealthDay News) — The bright lights of the big city might seem dazzling, but they can be hard on your heart health, a new study says.People exposed to high levels of artificial light have an increasingly higher risk of heart disease, researchers are scheduled to report at a Nov. 10 meeting of the American Heart Association in New Orleans.Higher exposure to artificial light at night was associated with a 35% increased risk of heart disease within five years, and a 22% increased risk over 10 years, researchers found.“We found a nearly linear relationship between nighttime light and heart disease: the more night-light exposure, the higher the risk,” senior researcher Dr. Shady Abohashem, head of PET/CT cardiac imaging trials at Massachusetts General Hospital in Boston, said in a news release.For the new study, researchers analyzed the health of 466 adults with an average age of 55 who’d undergone a PET or CT scan at Massachusetts General Hospital between 2005 and 2008.The team compared the participants’ health and brain scans to their exposure to artificial light, based on their home address.Results showed that higher levels of artificial light caused brain stress activity and blood vessel inflammation.“Even modest increases in night-time light were linked with higher brain and artery stress,” Abohashem said. “When the brain perceives stress, it activates signals that can trigger an immune response and inflame the blood vessels. Over time, this process can contribute to hardening of the arteries and increase the risk of heart attack and stroke.”Over a decade, 17% of the people developed a major heart condition. Their light exposure was associated with risk of heart disease, even after accounting for other risk factors.Heart risks were even higher among people who lived in areas with high traffic noise, lower neighborhood income or other environmental factors that can add to stress, researchers said.To counter these ill effects, “people can limit indoor nighttime light, keeping bedrooms dark and avoiding screens such as TVs and personal electronic devices before bed,” Abohashem said.Cities also might improve folks’ health by reducing unnecessary outdoor lighting, shielding street lamps, or using motion-sensitive lights, researchers said.“These findings are novel and add to the evidence suggesting that reducing exposure to excessive artificial light at night is a public health concern,” Julio Fernandez-Mendoza, an American Heart Association spokesman, said in a news release.“We know too much exposure to artificial light at night can harm your health, particularly increasing the risk of heart disease. However, we did not know how this harm happened,” said Fernandez-Mendoza, director of behavioral sleep medicine at Pennsylvania State University College of Medicine, who was not involved in the study.“This study has investigated one of several possible causes, which is how our brains respond to stress,” he explained. “This response seems to play a big role in linking artificial light at night to heart disease.”Researchers next plan to see whether reducing nighttime light exposure might improve people’s heart health.Findings presented at medical meetings should be considered preliminary until published in a peer-reviewed journal.SOURCE: American Heart Association, news release, Nov. 3, 2025Copyright © 2025 HealthDay.

THURSDAY, Oct. 9, 2025 (HealthDay News) — A new study suggests there’s more to sleep than how long you snooze each night. Your overall sleep pattern could shape your mood, brain function and even long-term health.Researchers from Concordia University in Montreal identified five distinct sleep profiles that may help explain why some people feel well-rested while others struggle with fatigue, poor focus or emotional ups and downs.The findings, published Oct. 7 in PLOS Biology, show that these “sleep-biopsychosocial profiles” reflect a mix of biological, mental and environmental factors — from stress and emotions to bedroom comfort — that all affect how well you sleep.“People should treat their sleep seriously,” study co-author Valeria Kebets, a manager at Concordia’s Applied AI Institute, told NBC News. “It affects everything in their daily functioning.”The researchers identified five sleep profiles:1. Poor sleep and mental healthPeople in this group reported the worst sleep quality and higher levels of stress, fear and anger. They also had a greater risk of anxiety and depression.These individuals had poor mental health or attention issues but said their sleep felt fine, suggesting “sleep misperception,” or being unaware of underlying sleep problems, researchers said.3. Sleep aids and sociabilityThis group used sleep aids, but also reported strong social support and fewer feelings of rejection. However, they showed lower emotional awareness and weaker memory.4. Sleep duration and cognitionPeople sleeping fewer than six to seven hours a night scored lower on tests measuring problem-solving and emotional processing. They also showed higher aggression and irritability.5. Sleep disturbances and mental healthThose with issues like frequent waking, pain or temperature imbalance had higher rates of anxiety, substance use and poor cognitive performance.The study analyzed data from 770 healthy adults aged 22 to 36, using MRI scans and questionnaires about sleep, lifestyle and mood.Experts say the profiles could help doctors tailor sleep treatments in the future.“We really need to consider multiple sleep profiles in our research and clinic — the value of a multidimensional approach to data,” Dr. Phyllis Zee, director of the Center for Circadian and Sleep Medicine at Northwestern University, who was not involved in the study, told NBC News.Sleep experts also say the research reinforces the importance of good rest for both mental and physical health.“Sleep is a more complex issue than just how much time you spend in bed,” Dr. Rafael Pelayo, a sleep medicine specialist at Stanford University, said in the NBC News report. “If I can improve your sleep, it has downwind effects on your overall health — not just your mental health, but your physical health.”SOURCE: NBC News, Oct. 8, 2025Copyright © 2025 HealthDay.

This life sustaining force is only seen where it bubbles up to the surface through Florida’s collection of 1,000 springs. These springs were originally what drew society to this land. Wealthy tourists in the 1900’s flooded the Florida springs seeking medicinal cures from its pristine waters. As springs became a popular tourist destination, spring houses were built around these pools of water. When this development began, the springs began flowing less and some eventually stopped altogether. People assumed this was the natural order of this wonder and moved on. Theme parks, golf courses and resorts were erected to entice tourists to visit Florida, the natural beauty of the state soon faded out of our memory. The springs of Florida now silently suffer from the effects of continued development in Florida. The current strain we are placing on the fragile ecosystem is choking the life out of our state. Overdevelopment is one of the leading forces that is damaging the springs. The once pure sources of water no longer boil up like a fountain the way they have for centuries. The water that the springs do produce is polluted by nitrates. This pollution fuels the growth of toxic algae blooms, which are taking over springs and the rivers they feed, thus putting our health at risk. Over 90% of our drinking water gushes out of these sapphire pools. These glorious reservoirs have begun to shrink. If something is not done soon, the springs will simply become part of Florida history. In southern Florida they already have. Springs once bubbled up all across the state. They were wiped out in South Florida decades ago by the ditching and draining of the landscape as well as over-pumping of the aquifer. This water was then sprayed on suburban lawns and farmers' fields, run through showers and flushed down toilets, turned into steam to crank turbines for electricity, or siphoned into plastic bottles for sale around the country. Because of poor use and neglect of our greatest resource, we will soon be without this supply of fresh water. Floridians regard their water supply as abundant and cheap, when the fact is it's neither. Until this attitude changes, the springs will not be rescued.

Allergy Alert: Paranoia in Our Immune System

From peanuts and pollen to cats and dust mites, allergy rates are soaring dramatically all over the globe, with inoffensive substances triggering life-threatening physical responses. Experts are predicting that by 2050, one in two will suffer from an allergy. Why are our immune systems overreacting in this way? To stem the tide of the epidemic, scientists are investigating the interface between genetics, environmental factors and our modern lifestyle, and developing revolutionary new approaches to prevention and treatment.
