What You'll Learn
Industrial and agricultural pollution
The Cape Fear River Basin is the largest river system in North Carolina, providing drinking water to a fifth of the state's residents. However, the river system faces significant challenges due to industrial and agricultural pollution.
Agricultural operations and urban centres contribute to polluted runoff into the Cape Fear River. Farmers' practices that reduce soil erosion, limit water use, and sustain the land have helped. However, with climate change, flooding and droughts impact the river, and new unregulated chemical pollutants from manufacturing industries enter the basin.
The river's watershed is highly industrialized, with various land uses, including timber harvesting and high-density animal feeding operations. Animal feedlots for turkey, chicken, and hog production are a significant industry. These activities contribute to the pollution problems within the basin, and the subsequent degradation of wildlife habitats.
The river has also faced issues with chemical contamination. The Chemours Company has discharged waste containing perfluoroalkyl and polyfluoroalkyl substances (PFAS) into the river for decades, polluting the water supply downstream. This has resulted in contamination in the water, soil, and people's bodies, causing health issues for residents.
In addition to chemical pollution, the river is impacted by sediment and nutrient pollution, which can cause algal blooms. These blooms can be harmful to both wildlife and people, as evidenced by the deaths of multiple dogs that swam in Jordan Lake.
To address these issues, local cities, industries, environmental groups, and regulatory agencies are working together to improve water quality. Efforts have led to improved technology in wastewater treatment plants and better stormwater pollution prevention practices. Additionally, strategies such as riparian buffers are being explored to mitigate pollution and protect water quality.

Urbanisation and suburbanisation
The Cape Fear River Basin is the largest of four watersheds entirely contained within North Carolina. It provides drinking water for millions of people in the state, including in the cities of Greensboro, Durham, and Fayetteville, as well as in coastal communities such as Southport and Wilmington.
The population in the Cape Fear River watershed has been growing dramatically in recent years, driven by significant urbanization and suburbanization. This has resulted in sprawling development that was not designed with protections for clean water in mind. As natural land cover is replaced with impervious surfaces such as parking lots and sidewalks, the frequency and volume of stormwater runoff increase, carrying more pollutants into the waterways. This has stressed drinking water systems, inhibited groundwater recharge, and contributed to habitat destruction.
The river has also been largely separated from its floodplain, limiting its ability to be resilient to climate change. With climate change accelerating, the Cape Fear River Basin is expected to face more extreme flooding and droughts in the coming decades, exacerbating existing water quality issues.
In addition to the impacts of urbanization and suburbanization, the Cape Fear River is also affected by agricultural operations, industrial activities, and the use of unregulated chemical pollutants by the manufacturing industry. These issues collectively create a significant problem for the health of the river and the communities that depend on it.

Climate change
One of the key challenges facing the Cape Fear River is polluted runoff from growing urban centres and agricultural operations, which has been made worse by climate change. The significant urbanization and subsequent suburbanization of the Cape Fear River watershed have resulted in sprawling development without adequate protections for clean water. This has led to excessive stormwater runoff that washes pollutants into the river. Climate change has also contributed to the occurrence of huge flooding events and historic droughts in the region, further complicating the issue of pollution in the river.
The river's separation from its floodplain limits its ability to adapt to climate change. To address this, organizations like The Nature Conservancy are working to restore the hydrology of peatlands in coastal North Carolina, as part of the Sustainable Rivers Program (SRP). This initiative aims to manage the Cape Fear River and enhance its resilience to climate change.
Additionally, the impacts of climate change and pollution on the Cape Fear River have led to the loss of critical habitats. In response, NOAA and its partners have collaborated with local communities and nonprofit organizations to purchase and preserve 1,700 acres of wetland and floodplain habitats. These conservation efforts not only improve community and environmental resilience but also help to compensate for habitats lost due to pollution and development.
The preserved properties, including freshwater tidal marsh and cypress swamp habitats, act as blue carbon sinks, sequestering and storing carbon. They also provide room for the expected movement of tidal wetlands due to sea-level rise, a consequence of climate change. By buffering the impacts of flooding, these conservation projects enhance the resilience of the Cape Fear communities, ensuring their protection for years to come.

Chemical contamination
The Cape Fear River Basin is North Carolina's largest river system, providing drinking water to a fifth of North Carolinians. However, the river system faces significant challenges due to chemical contamination.
One of the primary sources of chemical contamination in the Cape Fear River is the discharge of waste from industrial facilities. The Chemours Company, for instance, has been accused of releasing toxic chemicals, including GenX, into the river. GenX is a chemical used to make nonstick products, and its presence in the water supply has raised concerns about its potential health risks. As a result of this contamination, residents of North Carolina have taken legal action against Chemours, resulting in a settlement that required the company to cease discharges and implement measures to prevent airborne PFAS pollution.
In addition to GenX, the Cape Fear River has also been contaminated with perfluoroalkyl and polyfluoroalkyl substances (PFAS). PFAS are persistent chemicals that have been used by the manufacturing industry throughout the basin. The presence of PFAS in the river is a significant concern as these chemicals are known to have adverse effects on human health and the environment.
Agricultural operations also contribute to chemical contamination in the Cape Fear River. The use of pesticides, fertilizers, and other chemicals in farming can lead to runoff that pollutes the river. Additionally, the high-density animal feeding operations within the basin, such as turkey, chicken, and hog production, can result in the release of harmful chemicals and waste into the river.
The expanding population and urbanization in the Cape Fear River watershed have further exacerbated the issue of chemical contamination. As more people move into the area, there is an increased demand for water, which puts additional strain on the river. Furthermore, the development of impermeable surfaces, such as concrete and asphalt, can lead to increased stormwater runoff, carrying pollutants into the river.
Climate change also plays a role in the chemical contamination of the Cape Fear River. The combination of heavier rains and extreme flooding can increase the volume of water in the river, diluting the concentration of chemicals and spreading them over a larger area. Additionally, drought conditions can lower water levels, concentrating pollutants and making them more hazardous.

Water treatment
The Cape Fear River Basin is the largest river system in North Carolina, covering over 6,500 miles of streams and rivers and providing drinking water to a fifth of the state's residents across 29 counties. The river has been subjected to various sources of pollution, threatening the health of the river and the communities that depend on it.
One significant issue is the discharge of wastewater from cities. Wastewater treatment plants play a crucial role in reducing harmful bacteria and pollutants in the water. Conservation organizations work to identify priority areas for conservation and restoration, filling data gaps by creating models that give a comprehensive understanding of water quality across the basin. These models consider factors such as land use, point source discharges, runoff, and weather conditions.
Another critical aspect of water treatment in the Cape Fear River is addressing polluted runoff from urban centres and agricultural operations. Crop farmers have adopted practices that reduce soil erosion, limit water use, and better sustain the land. However, with the impacts of climate change, such as heavier rains and more frequent flooding and droughts, treating polluted runoff remains a challenge.
Additionally, strategic buffers have been proposed to mitigate pollution. Researchers are studying the impact of placing buffers of varying widths in upstream locations with high pollution concentrations. While North Carolina already mandates 50-foot riparian buffers in some watersheds, customizable buffers tailored to each watershed's unique processes may be more effective in reducing pollution.
The Cape Fear River Watch, a volunteer watchdog group, has actively advocated for the river's protection. They have taken legal action against polluters, such as suing the North Carolina Department of Environmental Quality (NCDEQ) and Chemours to stop polluting the river with PFAS (per- and polyfluoroalkyl substances). These efforts have led to consent orders requiring polluters to cease discharges and implement measures to prevent future pollution.
