New study finds elevated cancer rates near toxic San Jacinto River waste pits
The study, which was published earlier this month, analyzed cancer rates across 65 census tracts surrounding the San Jacinto River both upstream and downstream of the San Jacinto River Waste Pits Superfund Site, which is contaminated with carcinogenic waste. Between 2013 and 2021, the study found, people in the area had cancer rates above the expected range for cervix uteri cancer, leukemia, lung and bronchus cancer and lymphoma.
The Superfund site near Houston is contaminated with dioxins, which the Environmental Protection Agency says are highly toxic and can cause cancer, reproductive and developmental problems, damage to the immune system, and can interfere with hormones.
The Texas Department of State Health Services said the cancer assessment was not intended to determine the cause of the cancers or identify possible associations with any risk factors. But environmental advocates said the assement's findings renewed calls for the cleanup of the Superfund site, an effort which has faced several delays due to disputes over who is responsible.
Jackie Medcalf, founder and CEO of the environmental nonprofit Texas Health and Environment Alliance, called the state's new study a wake-up call for state and federal officials.
'Our bodies are toxic soup and we cannot ignore that any longer,' Medcalf said Monday at a press conference at the San Jacinto Community Center.
The study also reviewed seven types of childhood cancer. Results showed cancer cases were within the range of what is expected based on cancer rates in Texas.
The site's pits were originally constructed in the 1960s to dispose of solid and liquid pulp and paper mill waste from the International Paper Co. and McGinnes Industrial Maintenance Corp. During this time the EPA didn't know the risk of such contamination.
As much as 200,000 cubic yards of highly toxic waste was dumped into the pits and later eroded allowing for contaminants to leak into the San Jacinto River. In 2008, the site was added to the EPA's National Priorities List for cleanup under the Superfund program, which ranks 'the nation's most serious uncontrolled or abandoned hazardous waste sites.'
For decades residents in the area say they unknowingly lived, swam, boated and fished near and on top of a hazardous waste site.
Gene Hennigan is a long-time resident of Lynchburg, an unincorporated community located in east Harris County and near the waste site. At the press conference Hennigan said he knows many people in the community who have suffered from cancer, including his wife and son who died of cancer.
'The list goes on,' he said. 'We know the area is a cancer cluster by experience not by a study.'
THEA and local residents requested the state to study the area's cancer rates.
In 2011 temporary armored caps were installed to contain toxic sludge at the site. However, six years later Hurricane Harvey damaged the caps, exposing the waste. Environmentalists and lawyers have argued the temporary cap is an insufficient fix and continue to push for expedited removal of the waste to prevent further human and environmental harm. Full remediation of the site has a price tag of $115 million.
Medcalf with THEA said she is frustrated that the EPA hasn't taken stronger action to clean up the site. The agency could take over the clean up. However, she's hoping the Trump administration will prioritize the cleanup of hazardous waste sites, as she said he did during the prior administration by creating a Superfund Task Force.
THEA will be meeting with the state health department Tuesday and with the EPA later this week to discuss the cancer assessment's findings.

Legionnaires' outbreak in New York grows to 90 cases, 3 deaths
Health officials in New York said a Legionnaires' disease outbreak in Central Harlem has now sickened 90 people and caused three deaths. File Photo by SHOU SHENG/EPA A Legionnaires' disease outbreak in Central Harlem has now sickened 90 people and caused three deaths, New York City health officials said Tuesday. The update comes just a few days after the city's health department proposed new rules for the testing of building cooling towers, suspected origin of the outbreak. Cooling towers are large rooftop devices that release mist into the air to help cool buildings. But if the water inside the tower becomes too warm or isn't disinfected properly, bacteria called Legionella can grow. People can get sick when they inhale this contaminated mist. A Department of Health spokesperson told CNN that the proposed rules "were in development well before the Legionnaires' cluster in Central Harlem." Under current city law, building owners must register and maintain their cooling towers, which are regularly inspected, CNN said. The new proposal would set strict timelines for testing, require analysis of samples by state-certified labs and impose fines for noncompliance. Financial penalties have not been specified. Right now, failing to follow maintenance rules can bring fines of $500 to $2,000. Still, enforcement could be difficult. Inspections have dropped sharply, city data shows, with fewer than half as many in 2024 compared to 2017, when the city began tracking numbers, according to Gothamist, a non-profit newsroom affiliated with WNYC public radio. The cluster was announced July 25. Health officials say all working cooling towers in the affected area have been tested, and those with Legionella have been cleaned. Legionnaires' disease is a type of pneumonia, the U.S. Centers for Disease Control and Prevention says. Symptoms can include: Cough, fever, headaches, muscles aches and shortness of breath. The infection can be treated with antibiotics. Left untreated, it may lead to serious complications like lung failure or death. Each year, around 6,000 cases are reported in the U.S., the Occupational Safety and Health Administration (OSHA) says. Health officials suspect the true number is higher, however, because it can be hard to tell Legionnaires' apart from other types of pneumonia.

Several beaches in Bay County are under a health advisory due to water quality
PANAMA CITY — Four local beaches are under health advisories for a high abundance of a fecal indicator bacteria. Carl Gray Park, Earl Gilbert Park, Laguna Beach and the Panama City Beach City Pier were all ranked as poor for levels of enterococcus bacteria. Carl Gray Park has been under an advisory since July 21. The advisory is new for all other affected locations. The Florida Department of Health in Bay County is advising against any water-related activities at these locations. Enterococci bacteria live in the intestines of warm-blooded animals and are used as an indicator of potential fecal contamination of surface waters. The Environmental Protection Agency says leaky septic systems, stormwater runoff, effluent from wastewater treatment plants, discharge from boats, and agricultural runoff are all sources of fecal indicator bacteria. The News Herald previously reported that aging wastewater infrastructure in Bay County can sometimes lead to sanitary sewer overflows, especially during extreme rain events. While the bacteria itself isn't harmful to people, it indicates that other pathogens that can cause sickness are present. Swimming isn't the only way to be exposed; eating raw fish or shellfish from affected waters can also cause illness. Being in affected waters could lead to gastrointestinal disease, infections, or rashes, according to the Florida Healthy Beaches Program. Bay County advises residents to have septic tanks pumped and inspected every three to five years to prevent leaking. They also ask that pet waste be flushed or thrown into the garbage. The county also advises that lawn chemicals be used wisely and that fertilizer be used sparingly. They say that excess fertilizer flows downstream and often results in algae blooms in ponds and lakes.

Study Reveals PTSD, Depression Spike After East Palestine Train Disaster
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Researchers have found that cases of depression, post-traumatic stress disorder (PTSD) and lack of trust in public officials are rising roughly two-and-a-half years after a Norfolk Southern train derailed and spilled toxic chemicals in East Palestine, Ohio. Why It Matters On February 3, 2023, a freight train carrying toxic chemicals—including vinyl chloride, butyl acrylate, ethylhexyl acrylate and ethylene glycol monobutyl—derailed in East Palestine about a quarter mile west of the Ohio-Pennsylvania state line and spilled toxins in a waterway feeding into the Ohio River. National attention was paid to the incident due to nefarious effects on locals and the broader environment. Then-President Joe Biden and his administration were ridiculed for their response, accused of not publicly releasing concerning health information while not providing Americans with sufficient information. President Donald Trump, in the infancy of his third presidential campaign, traveled to East Palestine shortly after the derailment to show support for the community and touted the impact of his visit shortly thereafter on social media. What To Know Researchers who co-authored what they described as the most comprehensive study yet on the aftermath of the derailment spoke with Newsweek about their findings, published Tuesday in the Journal of Traumatic Stress. The study, titled "Prevalence of PTSD and Major Depression in Ohio, Pennsylvania, and West Virginia 9 Months After the East Palestine Train Derailment," was funded in part by the National Institutes of Health. The study correlates upticks in mental disorders among potentially exposed residents of Ohio, Pennsylvania and West Virginia roughly nine months post-derailment. The cross-sectional study, consisting of a nonprobability sample of 1,000 adults living within 65 miles of the derailment site and who completed a self-administered clinical survey interview, assessed PTSD and major depression, physical health symptoms, negative derailment-related beliefs and experiences, and preexisting psychiatric risk factors. Ohio EPA and EPA contractors collect soil and air samples from the derailment site on March 9, 2023 in East Palestine, Ohio. Ohio EPA and EPA contractors collect soil and air samples from the derailment site on March 9, 2023 in East Palestine, peer-reviewed study's most notable findings show upticks, including: Approximately 15 percent of respondents met criteria for presumptive PTSD symptoms, more than twice the national average. Approximately 13 percent met criteria for major depression, about 60 percent greater than the national average. About half of respondents within proximity of the disaster have reported new or worsening physical symptoms including coughing, fatigue and eye irritation. Those living closer to the scene of the accident reported higher incidents. More than half of residents said they had little to no confidence in public officials during and after the incident, expressing a distrust of public officials and uncertainty about chemical exposure. Effects of Disasters On Mental Health "What we noticed was in that aftermath of the derailment, in addition to these concerns around exposure that were being reported by a lot of news sources at the time—there was a lot of initial data to suggest that these people were reporting physical and mental health problems as well," study co-author Dr. Cameron Pugach of the Medical University of South Carolina told Newsweek. "So, we were really motivated in this study to provide the first kind of comprehensive investigation and in a large-scale mental health survey to kind of quantify the extent to which people were reporting these mental health problems and these physical health problems, and the extent to which people were actually reporting these levels of concerns specifically associated with with toxic substance exposure," Pugach continued. Along with the mental health consequences, he noted how nearly three-quarters (73.9 percent) of respondents were concerned about potential toxic exposure, while another 92.1 percent were wary about associated health problems. Also, about half the respondents reported at least one physical health problem following the derailment—with respiratory and gastrointestinal problems being the most common. "When you look at like national level data, for example on PTSD, the rates that are being reported in the sample in and around East Palestine are over twice the prevalence of the national estimates of PTSD in the U.S., so they're quite elevated," Pugach said. "I think it's pretty comparable to what you'd see in other kinds of disasters like this." Aaron Reuben, study co-author and an assistant professor of neuropsychology at the University of Virginia, said these types of mental health surveys became more customary following major disasters and cultural events, like the September 11 attacks or Flint water crisis—the latter of which also resulted in long-lasting psychiatric problems, including increases in reported PTSD and depression. "There's an interesting phenomenon with this event, which is that it was very dramatic. It was highly publicized," Reuben told Newsweek via phone. "And if you lived in the area, because they burned so many tanks worth of chemicals, you know they were worried about explosion. The sky was filled with these extremely dramatic plumes, what we know to be toxic that you would absolutely not want to be exposed to." He said evacuation efforts made within a mile of the site, coupled with burning tanks and broader efforts to mitigate the impacts that some studies ascertained reached some 14 percent of the United States, led to a lot of concerns. "We had a lot of dispersion, which means it could be a lot of people exposed to very little or some people exposed to very lot—and we just had no idea," Reuben said. "What we are seeing in our survey today is that uncertainty is leading to a lot of concern, a lot of feeling like you're having physical health symptoms that are the kind you would experience if you had been exposed. "Then, a lot of mental health problems that actually are significant and numerous and severe enough that if you were to walk into a clinic, we would diagnose you with a condition that needs to be treated. What we're seeing is a really unique event." Reuben said the extent to which he and fellow researchers think people will recover is going to vary person to person, adding that he wouldn't be confident that "anything would have changed" if they conducted a similar survey a year from now. Pugach said that long-term longitudinal research that samples PTSD, from a general standpoint, shows that once developed, PTSD is a fairly chronic condition among people who develop it, and it tends to kind of stick around unless people are actively seeking trauma-focused treatment. One prong of the research is finding how to help the people who have already experienced the trend in and around East Palestine. The second is how researchers can use this data to inform and improve responses to disasters when they happen in the future in other communities, he said. "Improving kind of the credibility and the quality of information people are receiving in the short-term aftermath of disasters like this is going to help, I think, address people's uncertainty around like exposure itself," Pugach said. "And we know that those factors are associated with the extent to which people are reporting things like PTSD and depression. "I think receiving that quality information from trusted officials is really going to help people in kind of managing their symptoms in the aftermath of these kinds of events." What People Are Saying Study co-author Dean Kilpatrick, of the Department of Psychiatry and Behavioral Sciences, at the Medical University of South Carolina, in a statement: "In the future we may need to attend more in advance to limit psychological uncertainty after these events. Providing communities with timely and credible information about the likelihood of exposures should be considered front-line responses." What Happens Next A July 2025 update from the Environmental Protection Agency (EPA) stated that as restoration nears completion, the cleanup area of the derailment site is shrinking and crews are assessing waterways for remaining oily sheens and to determine what additional cleanup may be needed. The National Institute of Environmental Health Sciences (NIEHS) issued a Research Opportunity Announcement (ROA) for organizations to participate in a study to address the immediate and longer-term health concerns from exposures to chemicals released during the train derailment. The proposed settlement (lodged consent decree) between the U.S. and Norfolk Southern includes creating a community health program to provide medical monitoring and mental health services. Groundwater, surface water and drinking water around the scene continue to be regularly sampled, per the EPA.
