TOMS RIVER, N.J. — The former Ciba-Geigy chemical plant poisoned the ground and water in Toms River, New Jersey, where the rate of childhood cancer cases rose significantly in the 1980s and 1990s.
It was one of the nation’s worst toxic waste sites, was added to the federal Superfund cleanup list and still has a vast plume of chemically contaminated groundwater beneath it.

State officials and the current owner of the site, German-based BASF Corp., think the fenced-off land, with some restoration work, could once again be fit for the public. Under a proposed settlement with New Jersey environmental regulators, BASF would carry out nine environmental projects including restoring wetlands and grassy areas; creating walking trails, boardwalks and an elevated viewing platform; preserving woodlands and building an environmental education center at a cost of about $30 million.

If two emotional public hearings are any indication, most residents of Toms River, an upscale Jersey Shore community about 55 miles north of Atlantic City, want the state to scrap the deal and start over.
In addition to a widespread feeling that the settlement fails to punish BASF for the conduct of Ciba-Geigy — something it is not designed to do — many residents still voice deep distrust not only of the company but of government, citing decades of neglect and lax oversight that allowed Ciba-Geigy to dump chemicals and dyes into the Toms River and directly onto the ground for years with impunity. As longtime environmental activist Peter Hibbard put it, “It was like they had a golden ticket to pollute.”
During a hearing March 13 that lasted nearly six hours, several residents said the site is too toxic — chemically and symbolically — to ever be used for anything again.

Summer Bardier speaks at a public hearing Monday in Toms River, N.J., at which she advocated letting the former Ciba-Geigy chemical plant site be reclaimed by nature and kept off-limits to people.
“Why not just re-wild the area?” asked Summer Bardier, whose uncle worked at the plant and when he came home on hot days would sweat the color of the dye he was working on. “Why potentially cause other people to be harmed, exposed, injured and possibly killed? That land is off-limits now; people don’t want to go back there.”
“The public is not going to want to use this for passive recreation,” resident Phil Solomon added.
Sean Moriarty, a deputy commissioner with the New Jersey Department of Environmental Protection, grew up next to the Ciba-Geigy plant; he and his friends would hop the fence and play in the plant’s woods, much to the dismay of his mother, a cancer nurse.
“I wouldn’t stand here tonight in front of a place that I still say that I am from if I didn’t personally believe in the settlement the DEP is proposing,” he said. In response to a question about whether he would build a house on the site and move his family there, Moriarty said he plans to bring his children to walk the trails once the projects are completed.
Starting in the 1950s, Ciba-Geigy Chemical Corp., the town’s largest employer, was flushing chemicals into the river and the Atlantic Ocean and burying 47,000 drums of toxic waste in the ground.
This created a plume of polluted water that spread beyond the site into residential neighborhoods.
While it has been reduced in size, the plume remains, and cleanup efforts will need to continue for years.
Officials say Toms River’s water is safe to drink.
The state health department found that 87 children in Toms River, which was then known as Dover Township, were diagnosed with cancer from 1979 through 1995. A study determined the rates of childhood cancers and leukemia in girls in Toms River “were significantly elevated when compared to state rates.” No similar rates were found for boys.
The company paid millions of dollars in fines and penalties on top of the $300 million it and its successors paid so far to clean up the 1,250-acre site — an ongoing effort with no end in sight.

A gate at the entrance to the former Ciba Geigy chemical plant is filled with warnings Jan. 24 regarding the contaminated area in Toms River, N.J., that is on the Superfund list of the nation's worst toxic waste sites.
The settlement announced in December aims to have BASF — the corporate successor to Ciba-Geigy — compensate New Jersey for the environmental damage done by decades of pollution.
But instead of simply writing a check, the deal obligates BASF to preserve enough land to recharge groundwater that was polluted when Ciba-Geigy dumped chemicals into pits or directly onto the ground.
BASF said it remains committed to the settlement, which has yet to be finalized.
“We look forward to preserving the land, implementing the planned restoration projects, and opening new possibilities to encourage recreation, learning and community engagement at the site,” company spokesperson Molly Birman said. She noted the company continues to carry out its responsibility to treat groundwater at and near the site, which is separate from the proposed natural resources settlement.
In 1992, Ciba-Geigy paid $63.8 million to settle criminal charges that it illegally disposed of hazardous waste, and it and two other companies reached a $13.2 million settlement with 69 families whose children were diagnosed with cancer.
Here are the places where air pollution levels could soon be considered dangerous by the EPA
Here are the places where air pollution levels could soon be considered dangerous by the EPA

The average healthy person takes about 22,000 breaths per day. But depending on where you live in the United States, going outside for a few breaths of fresh air may be slowly killing you.
Millions nationwide live in regions where air pollution levels exceed what the Environmental Protection Agency considers safe. Children, older adults, people with preexisting heart or lung conditions, communities of color, and low-income communities are among the most vulnerable and most severely impacted by air pollution.
Exposure to air pollution is associated with over 100,000 premature deaths annually, most of those being people over age 65. By race, Black and Hispanic populations bear a disproportionate share of those deaths.
A majority of air pollution comes from burning fossil fuels like gasoline, diesel, oil, and wood. Tiny inhalable particle pollutants—just a fraction of the width of a single piece of human hair—form when compounds such as sulfur dioxide and nitrogen oxides emitted from power plants, industrial sites, and automobiles undergo chemical reactions in the atmosphere.
The most dangerous type of pollution is fine particle pollution or PM2.5. When inhaled, PM2.5 pollutants can travel deep into the lung tissue, enter the bloodstream, and create an increased risk of cardiovascular disease, respiratory illnesses such as asthma, and even lung cancer.
To better protect public health, the EPA's Clean Air Scientific Advisory Committee is seeking to make the standards around air quality and pollution stricter, leading to thousands of lives saved and billions of dollars added back into the economy.
Currently, PM2.5 levels are limited to 12 micrograms per cubic meter of air, as established by the standard set in 2012. The EPA proposes changing that limit to between 8 and 11 micrograms. Even within that range, the impact on public health can vary. A 2022 study commissioned by the Environmental Defense Fund found that an annual standard of 8 micrograms prevents more than four times as many premature deaths as a standard of 10 micrograms. Moreover, many experts, including medical professionals and environmental scientists, do not believe the proposed limits go far enough to address the threat to public health adequately.
Stacker cited data from the Environmental Protection Agency to look at what the agency's consideration of new particulate pollution standards means for people across the U.S.

At least 12 cities are already above recommended particulate standards

Race, more than income level, is an indicator of increased exposure to air pollution. In the U.S., PM2.5 pollution is disproportionately caused by non-Hispanic white populations and disproportionately inhaled by people of color, according to a 2019 study published in the Proceedings of the National Academy of Sciences.
A 2021 study funded by the EPA found that exposure disparities were greater between populations of color and white populations than between people at different income levels. Scientists are unable to definitively identify which emission sources cause this disparity.
Tightening the PM2.5 standard from 12 to 8 micrograms means more people, especially vulnerable communities, will be protected by enforced policy and regulatory measures in those regions as outlined in the Clean Air Act. Currently, 75% of Black Americans are exposed to PM2.5 concentrations greater than 8 micrograms each year, compared to 59% of white Americans.
Currently, 12 cities in the EPA's data have annual levels averaging over 12 micrograms per cubic meter. If the standard is lowered to 10, an additional 13 cities will fall above the standards. If lowered to 9, at least 32 cities would be above. This data represents less than a third of Census metropolitan areas, meaning other cities with missing data could also find themselves above new standards.

Air pollution has been linked to respiratory illness, cardiovascular disease, and cancer

Air pollution can cause short-term effects such as coughing, sneezing, and shortness of breath. It can also cause or worsen long-term conditions, including asthma, decreased lung function, irregular heartbeat, and heart attacks. Studies have shown that air pollution can even lead to lung cancer in people who have never smoked because some air pollutants promote rapid mutations of cells in the airways.
While no one is immune to the dangers of PM2.5 air pollution, children, the elderly, and individuals with preexisting heart and lung disease are especially vulnerable—as are people in low-income communities due to proximity to industrial sources of air pollution, underlying health conditions, and poor nutrition, among other factors. Low-income populations are 49% more likely to live in areas exceeding the current 12-microgram limit than wealthier populations. When exposure levels are looked at through a lens of racial disparity, Black, Hispanic, and Asian Americans are all exposed to levels higher than the national average of 6.5 micrograms. White Americans, by comparison, are exposed to levels averaging 5.9 micrograms.
Black populations are also dying from air pollution at a greater rate than anyone else. Black Americans over age 65 experience three times the number of PM2.5-attributable deaths per capita when compared to other races.
In some cities, reporting bad smells can help scientists identify sources of pollution

Air pollution is mostly invisible to the naked eye but can be more easily detected by our noses. Smell My City is an app developed by Carnegie Mellon University's CREATE Lab that uses crowdsourced reports of outdoor odors to identify potential health risks and sources of pollution.
In an interview with Stacker, Ana Hoffman, director of air quality engagement at the CREATE Lab, said that odor reporting has enabled community engagement on the topic of air quality, and as a result, engagement with many different government agencies, allowing residents to demonstrate, with data, the reality of their lived experiences.
A 2022 analysis of more than five years of Smell My City data revealed several pollution events detected by residents living near industrial operations in the Pittsburgh area. One notable data point was a sharp increase in smell reports described as "About as bad as it gets!" between 2018 and 2019. The source, Hoffman explained, was a fire at the U.S. Steel Clairton Coke Works in Allegheny County, Pennsylvania, which took its sulfur pollution controls offline for three months.
"People were breathing raw coke oven gas for that entire time throughout our region. It was not the first or last fire at Clairton Coke Works that happened," Hoffman added. "There's several more after that." Coke oven gas is comprised of a complex mixture of compounds, including carcinogenic hydrocarbons.
Since 2020, Clairton Coke Works has incurred more than 800 fines totaling $4.6 million from the Allegheny County Health Department.
