The Hudson River is steeped in American history, but it is also steeped in industrial pollution. Between 1947 and 1977, General Electric (GE) polluted the river by discharging polychlorinated biphenyls (PCBs), causing harmful effects to wildlife and people who eat fish from the river. Despite cleanup efforts, the river remains heavily polluted, with PCB levels still dangerously high. GE has been conducting ongoing assessments of the contamination and is working with the EPA to address the issue. The Hudson River is classified by the EPA as a Superfund site, meaning it requires close federal oversight and cleanup. The river is not recommended for swimming or drinking, and eating fish from the river is considered dangerous due to PCB contamination.

What You'll Learn
The Hudson River is a Superfund site
General Electric (GE) is a major contributor to the pollution of the Hudson River. Between 1947 and 1977, GE discharged approximately 1.3 million pounds of polychlorinated biphenyls (PCBs) from its capacitor manufacturing plants in Hudson Falls and Fort Edward, New York. PCBs are highly toxic compounds that have been linked to cancer and other serious health issues. They persist in the river sediment, continuing to move with the river's flow and contributing to its degradation.
Other sources of pollution include mercury contamination, untreated sewage discharges, heavy metals, furans, dioxins, pesticides, and polycyclic aromatic hydrocarbons (PAHs). These pollutants have had harmful effects on wildlife and people who consume fish from the river.
In response to the contamination, activists and environmental groups have advocated for the river's cleanup. The EPA has implemented various programs to address the pollution, including sediment removal operations and wastewater discharge permits. GE has also been directed to undertake additional sampling and analysis of PCB damage in the Lower Hudson to determine the need for further cleanup actions.
The Hudson River Superfund Site, spanning 200 miles from Hudson Falls to New York City, is one of the largest hazardous waste sites in the nation. The river's cleanup is a long-term process, and effective action is crucial to mitigate the health risks and ecological impacts of the pollution.

GE dumped 1.3 million pounds of PCBs
The Hudson River has been the focus of a long-term cleanup initiative after years of corporate pollution. Between 1947 and 1977, General Electric (GE) discharged approximately 1.3 million pounds of polychlorinated biphenyls (PCBs) into the river from its capacitor manufacturing plants in Hudson Falls and Fort Edward, New York. PCBs are highly carcinogenic compounds that have caused a range of harmful effects on wildlife and people who eat fish from the river.
GE's actions have had a significant impact on the environment and public health. PCBs have accumulated in the food chain, with cancer-causing compounds found in Hudson River fish. This has led to the closure of the once-thriving commercial fishing industry in the Hudson and rendered the Champlain Canal inoperative for commercial shipping. In addition, PCBs have contaminated the river sediment, and their persistence in the environment poses a continued risk to human health, even after the passage of time.
In response to the contamination, activists and environmentalists have advocated for the removal of PCBs from the river. The federal Clean Water Act, passed in 1972, and the Toxic Substances Control Act of 1976 were enacted in part due to nationwide environmental activism. The 200-mile stretch of the river was designated as a Superfund site in 1984, requiring extensive remediation actions.
GE has been ordered to clean up the Hudson River and remove the toxic PCBs. The company has conducted ongoing assessments of the contamination and initiated the first phase of their cleanup process in 2009. However, there are concerns that GE's current plans may not be sufficient to address the extent of the pollution. According to the Hudson River Trustees, the group responsible for assessing the environmental costs of PCB contamination, GE's dredging plans could leave behind significant amounts of PCBs, compromising the river's ability to thrive again.
The EPA has played a critical role in overseeing GE's efforts and holding the company accountable for its PCB pollution. The agency has agreed with GE to perform sampling in the Lower Hudson River to enhance knowledge about legacy pollutants and their impact. The EPA's plan includes the removal of 2.65 million cubic yards of sediment through dredging, a process that GE initially opposed. The cleanup is expected to cost GE $500 million, and the company has filed a lawsuit challenging the constitutionality of the Superfund law.

PCBs cause cancer and other health issues
The Hudson River has been polluted by industrial waste, including polychlorinated biphenyls (PCBs), discharged by the General Electric Company (GE) into the river from its capacitor manufacturing plants in Hudson Falls and Fort Edward, New York. GE is believed to have discharged approximately 1.3 million pounds of PCBs into the river between 1947 and 1977.
PCBs are chemical compounds that were widely used in industrial applications before their ban in the late 1970s due to health concerns. PCBs are harmful to human health and are considered a probable cause of cancer. They are known to cause genetic mutations and cellular damage, leading to the development of various types of cancer, including bladder cancer, non-Hodgkin lymphoma, and liver cancer. Exposure to PCBs can also cause immune system suppression, making individuals more susceptible to cancers. PCBs have also been linked to an increased risk of breast cancer, with studies showing a correlation between higher PCB levels in breast fat tissue and a higher clinical stage of breast cancer.
In addition to cancer, PCBs can cause other serious health issues. They can accumulate in fatty tissues and cause reproductive problems, immunological problems, and low birth weight. PCBs can also impact the nervous system and endocrine system, with some individual PCBs linked to an increased risk of breast cancer due to their effects on endocrine systems. The persistence of PCBs in the environment is a concern, as they degrade naturally over time through a process called natural dechlorination, but this does not make them harmless.
The contamination of the Hudson River by PCBs has led to health advisories in New York State, recommending limits on eating fish from the river. PCBs accumulate in the fish and can cause health issues for those who consume them. Women of childbearing age and children under 15 are advised to refrain from eating any fish from the Hudson River. The river has been designated as a Superfund site, and efforts are being made to clean up the pollution and restore the river's health.

The Clean Water Act and sewage treatment helped
The Hudson River has been polluted by industrial waste, mercury contamination, and untreated sewage discharge. In 1972, Congress passed the Clean Water Act, which established a nationwide discharge permit system for all surface waters. This act required all Hudson River point source dischargers to obtain permits from the New York State Department of Environmental Conservation (NYSDEC). As a result, there was an overall reduction in pollutant loadings to the river as factories, power plants, and municipalities improved their wastewater treatment systems.
One prominent example of a sewage plant upgrade was the North River Wastewater Treatment Plant in Manhattan. Before the plant opened in 1986, about 150 million gallons of untreated sewage were discharged into the Hudson River daily. The Clean Water Act also led to the implementation of wastewater discharge permits and the reduction of wastewater discharges. This helped initiate the extensive remediation actions on the river, which began in the 1970s.
The Clean Water Act and sewage treatment improvements have helped reduce pollution levels in the Hudson River. However, persistent pollutants such as polychlorinated biphenyls (PCBs) and heavy metals remain in the river's sediments. PCBs were widely used in the manufacture of electrical devices and were discharged into the river by General Electric (GE) between 1947 and 1977. The EPA banned PCB production in 1979, but the compound continues to pose a serious risk to human health and the environment due to its accumulation in the river sediment.
To address the PCB pollution, the EPA has initiated multiple five-year reviews under the Superfund law to ensure that remedial actions are effective and protective of human health and the environment. The EPA has also directed GE to undertake additional sampling in the Lower Hudson to address historic PCB contamination. Environmental advocacy groups, such as Scenic Hudson, Hudson River Sloop Clearwater, Hudson Riverkeeper, and the Natural Resources Defense Council, have played a crucial role in pushing for more action from GE and raising public awareness about the river's pollution.
The Clean Water Act and sewage treatment upgrades have significantly contributed to the reduction of pollution in the Hudson River. However, ongoing efforts are still necessary to address the persistent pollutants, such as PCBs, that remain in the river's ecosystem.

The EPA is overseeing GE's cleanup efforts
The Hudson River has been the focus of a long-term cleanup initiative after years of corporate pollution. Between 1947 and 1977, General Electric (GE) polluted the river by discharging polychlorinated biphenyls (PCBs), causing harm to wildlife and people who consumed fish from the river. In response, environmental activists protested and lobbied for action, leading to the passage of the federal Clean Water Act in 1972 and the Toxic Substances Control Act of 1976.
The U.S. Environmental Protection Agency (EPA) has played a crucial role in overseeing GE's cleanup efforts. In 1984, the EPA designated a 200-mile stretch of the river, from Hudson Falls to New York City, as a Superfund site requiring cleanup. This hazardous waste site is considered one of the largest in the nation. The EPA has worked with GE to develop and implement remediation plans, with GE bearing the financial burden.
One of the key components of the cleanup process is dredging, which involves removing contaminated sediments from the riverbed. In 2009, GE initiated the first phase of the cleanup process, including the removal of contaminated soil and sediments. By 2015, significant progress was made, with observers applauding the return of some wildlife. However, doubts remain about the effectiveness of GE's efforts, as studies continue to show significant levels of PCBs in the river.
To address these concerns, the EPA and GE entered into a settlement agreement in 2014, requiring GE to conduct a comprehensive study of the contamination in the shoreline areas of the Upper Hudson River. The study, estimated at $20.5 million, includes an assessment of PCB contamination in a 40-mile stretch of the river and the development of cleanup options. GE also agreed to reimburse the EPA for past costs related to the floodplain.
The EPA's review of the cleanup efforts has been ongoing, with the agency collecting and evaluating data on water, fish, and sediment. In 2025, the EPA finalized its third periodic review, concluding that PCB levels in water and fish were decreasing overall. However, the agency emphasized the need for more fish data to make science-based conclusions about the rate of recovery. The EPA remains committed to enhancing the monitoring program and conducting special studies to better understand the river's recovery.
The EPA's oversight of GE's cleanup efforts is a critical step towards restoring the health of the Hudson River and ensuring the safety of the surrounding communities. With the support of advocacy groups like Riverkeeper, the EPA continues to hold GE accountable for its PCB pollution and works towards a comprehensive solution to address the contamination.
