The Tennessee River is one of the most plastic-polluted rivers in the world. In 2017, a study found over 18,000 microplastic particles per cubic meter, more than in Europe's Rhine River or China's Yangtze River. The river is also affected by sedimentation, industrial pollution, coal mining, and sewage. Stormwater runoff, recognised as the largest threat to water quality in the US, increases bacteria such as E. coli and Giardia in the river. While the river is in a constant state of contamination, it is usually safe for swimming, except after heavy rainfall. Citizens and organisations are working to reduce pollution in the river by removing litter, installing Seabin skimmer devices, and adopting waterways.

The Tennessee River is one of the most plastic-polluted rivers in the world
In addition to microplastics, the Tennessee River is also contaminated by sedimentation, industrial pollution, coal mining and burning, and sewage. The river was also affected by the 2008 Kingston Fossil Plant coal ash spill, the largest industrial disaster in United States history. The spill released 1.1 billion gallons of coal ash into the Emory and Clinch Rivers, both tributaries of the Tennessee River. Coal-burning power plants are a major source of air pollutants, including mercury, carbon dioxide, sulfur dioxide, and nitrogen oxide, which can end up in the tissue of fish consumed by people.
Stormwater runoff is another significant contributor to the pollution of the Tennessee River. Runoff from paved surfaces, development, and lawns carries pollutants such as chemical fertilizers, oil, and litter into storm drains, which eventually lead to creeks and rivers. This can result in increased levels of bacteria, such as E. coli and Giardia, from sewage in the water. While the Tennessee River is in a constant state of contamination, it is usually safe for swimming for people without severe skin or gut sensitivities, unless there is a significant amount of stormwater runoff.
Organizations like Keep the Tennessee River Beautiful and Tennessee Riverkeeper are working to address the pollution in the river. Efforts include installing Seabin skimmer devices to remove litter and filter out pollutants, conducting cleanups to remove plastic litter, and promoting a reduction in single-use plastics and plastic packaging. Individual actions, such as picking up litter and refusing single-use shopping bags, can also help reduce plastic pollution in the river.
The Tennessee River's pollution has not gone unnoticed by officials, with increasing pollution being observed over the past two years. Data from the Environmental Protection Agency (EPA) indicates that around 60% of Tennessee's rivers are not safe for swimming due to pollution from industrial waste, sewage, and agricultural runoff. While the river is facing significant challenges, there are ongoing efforts to improve its water quality and reduce the impact of pollution on the environment and human health.

Stormwater runoff is the largest threat to the river's water quality
The Tennessee River is home to a substantial amount of pollution. A recent study found that 60% of Tennessee's rivers are too polluted for swimming and fishing. The river is polluted by microplastics, sedimentation, industrial pollution, coal mining and burning, and sewage.
The impact of stormwater runoff on water quality is particularly significant in developing and urban areas, where there is a higher proportion of impervious surfaces such as pavements and rooftops that do not allow rainwater to infiltrate the soil. Instead, the rainwater becomes stormwater runoff, carrying pollutants from roadways, such as chemical fertilizers, oil, and litter, into the river.
The Tennessee Riverkeeper organization works to address the issue of stormwater runoff by reviewing Clean Water Act permits for industrial dischargers and responding to citizen complaints. They also utilize emerging technologies, such as aerial surveillance, to investigate and address industrial discharges.
Public awareness and education are crucial in reducing stormwater pollution. Citizens can play a role in controlling stormwater pollution by maintaining buffer areas around streams, properly disposing of materials, and reporting any pollution or illegal dumping to the appropriate authorities. Additionally, refusing single-use plastics and reducing plastic waste can help to minimize the presence of microplastics in the river.

The river is unsafe for swimming due to bacterial contamination
The Tennessee River is one of the most plastic-polluted rivers in the world. It is in a constant state of contamination, with over 18,000 microplastic particles found per cubic meter. This is due to a culture of littering, a lack of involvement in recycling, and the excessive use of plastic packaging. The river is also affected by industrial waste, sewage, and agricultural runoff, which can lead to bacterial contamination.
According to the Environmental Protection Agency (EPA), around 60% of Tennessee's rivers are not safe for swimming. The Tennessee River is included in this assessment, with 122 miles of the river affected by bacterial contamination. This contamination is caused by the city's combined sewer and water system, which overflows during heavy rainfall, causing an increased level of bacteria, including E. coli and Giardia, in the water.
The Tennessee River is also impacted by industrial pollution, coal mining, and burning. In 2008, the river was affected by the Kingston Coal Ash Spill, the largest industrial disaster in US history, where 1.1 billion gallons of coal ash were released into two of its tributaries. The river's pollution is not limited to microplastics and bacteria, but also includes chemical fertilizers, oil, and litter, which are carried into the river through stormwater runoff.
While the river is typically safe for swimming for those without severe skin or gut sensitivities, the presence of stormwater runoff can make it unsafe for everyone. Organizations like Keep the Tennessee River Beautiful and Tennessee Riverkeeper are working to address this issue by installing Seabin skimmer devices and conducting cleanups to remove litter and microplastics from the river. Additionally, individuals can make a difference by picking up litter, reducing single-use plastic consumption, and participating in initiatives like RainSmart Yards to mitigate stormwater runoff.
In summary, the Tennessee River is unsafe for swimming due to bacterial contamination caused by stormwater runoff and the city's combined sewer and water system. The river's constant state of contamination, high levels of microplastic pollution, and the presence of industrial and agricultural pollutants contribute to the unsafe conditions for swimmers. Efforts are being made to improve water quality, but it is crucial for individuals and organizations to work together to address this issue effectively.

The river was affected by the coal ash spill at the Kingston Fossil Plant in 2008
The Tennessee River is one of the most polluted rivers in the world, with microplastics being a significant issue. Plastic bags, in particular, make up over half of the pollution in the river. The river was also affected by the coal ash spill at the Kingston Fossil Plant in 2008, which was a significant environmental and industrial disaster.
On December 22, 2008, the earthen wall of a containment pond at the Kingston Fossil Plant in Roane County, Tennessee, collapsed. This resulted in the release of approximately 1.1 billion US gallons (4.2 million cubic meters or 5.4 million cubic yards) of coal ash slurry, a toxic byproduct of coal combustion. The spill damaged multiple homes and flowed into nearby waterways, including the Emory River and Clinch River, both tributaries of the Tennessee River. It is considered the largest industrial spill in United States history.
The coal ash spill had severe environmental consequences. It killed and buried wildlife, including multiple deer and a dog, and resulted in a massive fish kill, with fish being ejected from the Emory River onto the river bank. The spill also contaminated the rivers with toxic coal ash, which poses risks to human health. The exact number of fish and other aquatic life affected is unknown, but it is reported that large numbers of dead fish were found as far as the Tennessee River and its other tributaries.
The spill also had long-term impacts on the area. The cleanup process was complex and challenging, and it took several years for the responsible parties to be held accountable. In August 2012, TVA was found liable for the spill, and in 2018, a federal jury ruled that the contractor hired for the cleanup did not properly inform and protect the workers, resulting in illnesses and deaths among them. The Tennessee Riverkeeper organization is working to develop a monitoring plan for these sites, as the disposal of dredged material presents significant challenges.

Citizens' lack of involvement in recycling contributes to microplastic pollution
The Tennessee River is one of the most polluted rivers in the United States. It is home to a substantial amount of pollution, including sedimentation, industrial pollution, coal mining and burning, and sewage. In addition, the river is also highly polluted with microplastics. In 2017, a study found over 18,000 microplastic particles per cubic meter, making it one of the most microplastic-polluted rivers globally. This is a significant issue as microplastics can be ingested and accumulated in the bodies and tissues of many organisms, including humans.
One of the main contributors to microplastic pollution in the Tennessee River is the lack of citizen involvement in recycling. Citizens' lack of participation in waste management and sorting practices leads to an increase in plastic waste being sent to landfills without treatment. This, in turn, contributes to the microplastic pollution in the river as untreated plastic waste can break down into smaller fragments, polluting the soil and water with microplastics.
The low recycling rates in the United States exacerbate the problem. Only 9% of plastic is recycled in the US, compared to 30% in Europe. This indicates a lack of priority given to recycling by citizens and the government. Additionally, single-use plastics, such as drink bottles, utensils, and bags, are a significant contributor to microplastic pollution. While bans on single-use plastics are becoming more popular, they may not always be effective due to factors such as cost and a lack of infrastructure for reusable alternatives.
To address the issue of citizens' lack of involvement in recycling and reduce microplastic pollution, it is crucial to increase public awareness and education about the impacts of plastic pollution on the environment and human health. Implementing policies that promote waste reduction, reuse, and recycling, such as the 3R concept, can also help encourage citizens to take an active role in waste management. Furthermore, supporting initiatives that remove litter and microplastics from the Tennessee River, such as the use of Seabin skimmer devices, is essential for mitigating the existing pollution levels.
Overall, citizens' lack of involvement in recycling contributes significantly to microplastic pollution in the Tennessee River. By increasing awareness, implementing effective policies, and supporting cleanup initiatives, we can work towards reducing the impact of microplastics on the environment and human health.
