The Fox River, a 182-mile-long tributary of Lake Michigan in Wisconsin, has a long history of pollution. Before the 1970s, untreated sewage and industrial waste were often dumped directly into the river. While the Clean Water Act of 1970 and 1972 brought about some improvements, the river continues to suffer from polluted runoff, lost wetlands, and chemical contamination. The Fox River has high levels of contaminants such as mercury, phosphorus, PCBs, and fecal bacteria. The pollution has resulted in restrictions on fishing and has impacted the health of the local population and wildlife. A $1 billion cleanup project was completed in 2020, but the river continues to be monitored, and challenges remain to restore the river to its former glory.

The Fox River has been contaminated by toxic waste from paper mills and other industries
The Fox River, a 182-mile-long tributary of the Green Bay in Wisconsin, has long been a source of water, food, jobs, and recreation for the region. However, it has also been contaminated by toxic waste from paper mills and other industries.
In the 1950s and 1960s, the mills along the Fox River routinely used Polychlorinated Biphenyls (PCBs) in their operations, which contaminated the river. PCBs are manufactured chemicals that have been widely dumped into the environment and do not degrade naturally. Instead, they concentrate in the environment and the food chain, resulting in health hazards to people, fish, and wildlife. The Wisconsin Department of Natural Resources explains that carbonless copy paper produced by the mills caused PCB pollution in the Fox River and Lake Michigan.
Public debate about the contamination of the Fox River began as early as 1923, but little was done to improve the river until the federal Clean Water Act was passed in 1970. This legislation helped to reduce poorly treated sewage and toxic effluent in the river, and water quality rapidly improved. In 1979, the federal government banned PCBs due to their environmental threat, and in 1998, the U.S. Environmental Protection Agency (EPA) proposed adding the Lower Fox River to the list of Superfund sites to be cleaned up.
The cleanup of the Lower Fox River, which began in 2004, involved dredging, capping, and sand covers to remediate PCB-contaminated sediment. The project concluded in 2020 and cost an estimated $1 billion. While the cleanup has reduced the risk to human health and the environment, PCB levels have not yet dropped to safe levels, and it is anticipated that it will take 10-30 years for fish tissue to recover.
In addition to PCB contamination, the Fox River has also faced other environmental challenges. Population growth and land development have resulted in increased untreated stormwater runoff, sediment dumping, and biological, chemical, and physical degradation of the river. Excess phosphorus has led to algal blooms, and the river has also been impacted by mercury and estrogenic compounds. Despite these challenges, the Fox River remains an important source of drinking water for over 330,000 people in towns like Elgin and Aurora, and efforts are ongoing to restore the river's health and protect its ecosystems.

The Clean Water Act of 1970 has improved water quality, but problems remain
The Clean Water Act of 1970 has been instrumental in improving water quality across the United States, including in the Fox River. This legislation was a federally funded mandate to help private and municipal dischargers meet new regulations to eliminate point sources (PS) of pollution into waterways.
The Fox River, a 182-mile-long tributary of Green Bay and Lake Michigan in Wisconsin, has a long history of pollution. The river's pollution issues began in the 1950s when mills along the river started producing and recycling carbonless copy paper, which caused PCB pollution. Despite a federal ban on PCBs in 1979, the river continued to suffer from biological, chemical, and physical degradation due to population growth and land development.
The Clean Water Act provided a basic structure for regulating pollutant discharges and set wastewater standards for industries. It made it unlawful to discharge any pollutant from a point source into navigable waters without a permit. This led to a reduction in poorly treated sewage and toxic effluent in the Fox River. The Act also provided grants to states, territories, and Indian tribes to support projects aimed at reducing nonpoint source pollution.
However, despite the improvements brought about by the Clean Water Act, problems remain in the Fox River. While some measures of pollution, such as dissolved oxygen levels, have improved, other measures, such as phosphorus levels and the presence of estrogenic compounds and pharmaceuticals, indicate that the river waters are slightly more contaminated than before 1972. The river continues to be impacted by the high concentration of paper mills and other industries along its banks.
Efforts to clean up the Fox River have been ongoing, with a $1 billion project concluding in 2020 that addressed PCB-contaminated sediment. The river will continue to be monitored by the Environmental Protection Agency and the Wisconsin Department of Natural Resources to ensure its health and protect the people and wildlife that depend on it.

PCBs, mercury, phosphorus, and other pollutants have been detected in the water
The Fox River in Wisconsin has a long history of pollution. Before the 1970s, untreated sewage and industrial waste were often dumped directly into the river. The Clean Water Act of 1970 and 1972 helped to improve water quality in the main stem of the river, but problems with pollution still exist.
The Fox River Implementation Plan (FRIP) has resulted in hundreds of millions of dollars being invested to reduce excess phosphorus, which leads to algae blooms that reduce dissolved oxygen levels and suffocate aquatic life. Mercury is another toxic metal contaminant that has been detected in the river. It damages the nervous system, causing shaking, tremors, pain, numbness, and other symptoms.
The Lower Fox River project involves the cleanup of sediment contaminated with PCBs, as well as the restoration of the natural resources damaged by these contaminants. Dredging of the chemicals in the river began in 2009, and the cleaning project concluded in 2020 at an estimated cost of $1 billion. Long-term monitoring and cap maintenance will continue for the foreseeable future to ensure the safety of the river.

The river supports wildlife and recreational activities, but the water is not safe for drinking
The Fox River in Wisconsin is a source of water, food, jobs, and recreation for the region. The river supports wildlife and is used for recreational activities like fishing, biking, walking, jogging, and rollerblading. However, the river has a history of pollution, and while it has improved over the years, the water is not safe for drinking.
The Fox River is the principal tributary of Green Bay and, via the bay, the largest tributary of Lake Michigan. The river has two distinct sections: the Upper Fox River, flowing from south-central Wisconsin into Lake Winnebago, and the Lower Fox River, flowing from Lake Winnebago into Green Bay. The Lower Fox River has been particularly affected by pollution.
Beginning in the 1950s, many mills along the Fox River started producing and recycling carbonless copy paper, which caused pollution in the river and Lake Michigan. The mills routinely used Polychlorinated Biphenyls (PCBs) in their operations, which contaminated the river. PCBs do not degrade naturally but instead concentrate in the environment and the food chain, posing health hazards to people, fish, and wildlife. In 1979, the federal government banned PCBs due to their environmental threat.
Efforts have been made to clean up the river, with dredging of chemicals beginning in 2009 and capping starting soon after. The cleanup project concluded in 2020, addressing approximately 6 million cubic yards of PCB-contaminated sediment. The Environmental Protection Agency (EPA) and Wisconsin Department of Natural Resources will continue to monitor the river for years to come.
While the cleanup efforts have improved water quality, the river is still not safe for drinking. The Illinois Environmental Protection Agency regularly conducts water quality testing and publishes the results in a biennial report. The report details the contaminants found, their locations, and potential sources. Contaminants detected in the Fox River include mercury, phosphorus, PCBs, fecal bacteria, and discarded pharmaceuticals.
Although the river supports wildlife and provides opportunities for recreational activities, the water is not suitable for drinking due to the presence of these contaminants. It is important for residents to be aware of the water quality and take precautions to protect their health.

Cleanup efforts have been led by the EPA and Wisconsin DNR, with responsible companies contributing
The Fox River in Wisconsin has faced pollution from untreated sewage, industrial waste, and chemical contaminants. Cleanup efforts have been led by the Environmental Protection Agency (EPA) and the Wisconsin Department of Natural Resources (DNR), with responsible companies contributing to restoration costs and activities.
The river, a vital source of water, food, jobs, and recreation for the region, has a long history of pollution. Before the 1970s, untreated sewage and industrial waste were commonly dumped into the river, leading to contaminated sediments. The Clean Water Act, enacted in 1970, marked the beginning of improvements, with further efforts initiated by the federal government's ban on PCBs in 1979.
The Lower Fox River, in particular, has been the focus of extensive cleanup campaigns due to its contamination with Polychlorinated Biphenyls (PCBs). PCBs are toxic chemicals that do not degrade naturally but instead accumulate in the environment and the food chain, posing significant health risks. The EPA and Wisconsin DNR have led projects to remediate PCB-contaminated sediments, reduce excess phosphorus, and restore the river's natural character by removing dams.
The cleanup efforts have involved dredging, capping, and sand covers to address the contaminated sediments. The responsible companies, including Glatfelter and Georgia-Pacific Consumer Products, have contributed financially to the cleanup costs and have been involved in long-term monitoring and cap maintenance. The Wisconsin DNR has also played a crucial role in restoring natural resources and protecting the river's ecosystems through initiatives like the Fox River Natural Resource Trustee Council.
While significant progress has been made, challenges remain. The EPA's five-year review concluded that PCB levels had not yet dropped to safe levels, and it is anticipated to take 10-30 years for fish tissue to recover. The river continues to be monitored by the EPA and Wisconsin DNR to ensure the effectiveness of the cleanup efforts and protect the health of the surrounding communities and ecosystems.

Frequently asked questions
The Fox River has a long history of pollution, with untreated sewage and industrial waste being dumped directly into the river before the 1970s. While there have been widespread efforts to clean up the river since then, it continues to face issues such as polluted runoff, lost wetlands, and non-native plant and animal invasions. The river contains contaminants such as mercury, phosphorus, PCBs, and fecal bacteria. As a result, the water is not considered safe for drinking, and recreational activities such as swimming are also impacted.
The Clean Water Act, enacted in 1970, has helped improve water quality by mandating the elimination of point sources of pollution. The Fox River Study Group (FRSG) has also developed the Fox River Implementation Plan (FRIP), which aims to reduce excess phosphorus and restore the natural character of the river by removing dams. Additionally, there have been dredging and capping projects to remove contaminated sediments from the riverbed.
Yes, the pollution in the Fox River poses risks to both human health and the environment. PCBs can bioaccumulate in the food chain, leading to health hazards for people, fish, and wildlife. Excessive levels of phosphorus have also led to algal blooms, which can make the water smell bad and kill aquatic organisms.
