The Cape Fear River is a 191.08-mile (307.51 km) long[5] blackwater river in east central North Carolina. It flows into the Atlantic Ocean near Cape Fear, from which it takes its name. The river also has several pollutants, ranging from suspended solids and runoff to manmade chemicals like GenX.

Variant names[edit]

According to the Geographic Names Information System, it has also been known historically as:[6]

  • Cape Fair River
  • Cape-Feare River
  • Charle River
  • Charles River
  • Clarendon River
  • North East Cape Fear River
  • North West Branch
  • Rio Jorda


The Cape Fear River at Smith Creek in Wilmington, NC.

It is formed at Haywood, near the county line between Lee and Chatham counties, by the confluence of the Deep and Haw rivers just below Jordan Lake. It flows southeast past Lillington, Fayetteville, and Elizabethtown, then receives the Black River approximately 10 miles (16 km) northwest of Wilmington. At Wilmington, it receives the Northeast Cape Fear River and Brunswick River, turns south, widening as an estuary and entering the Atlantic approximately 3 miles (5 km) west of Cape Fear.

During the colonial era, the river provided a principal transportation route to the interior of North Carolina.[7] Today the river is navigable as far as Fayetteville through a series of locks and dams. The estuary of the river furnishes a segment of the route of the Intracoastal Waterway.

The East Coast Greenway runs along the river.



Of all the rivers within North Carolina, The Cape Fear River has the largest river basin. It covers 9,149 square miles and, with a basin of this size, there is a large amount of land from which runoff can be produced.[8] Cities and farmland that surround the river and its tributaries have the ability to impact the water quality of the Cape Fear River.[9] The Cape Fear River is negatively impacted by point source and nonpoint sources of pollution. Some examples of nonpoint sources within the Cape Fear River include farms, city runoff, and erosion of the river's banks, which input pollution such as harmful chemicals, and fertilizers, and larger sediments like suspended solids.[8][9][10] As with any river, the water quality varies in different regions and is dependent on specific abiotic and biotic factors within the region.[8]

Suspended Solids[edit]

Suspended solids refers to any particle (living or nonliving) discharged into an aquatic system that remains in suspension. These particles often find their way into river systems via nonpoint source pollution as well as through larger point source pollution events such as Hurricane Florence In 2018. The stress of this storm led to a dam failure causing a mass leakage of coal ash into the Cape Fear River about five miles northwest of Wilmington, North Carolina.

GenX Chemicals[edit]

GenX is a chemical in the group of man made per- and polyfluoroalkyl substances, or PFAs. These substances are used for non-stick, water and stain repellent items. GenX is a replacement PFA, since older and more toxic PFAs are being phased out.[11] GenX is made at the Chemours plant in Fayetteville, NC and has gotten into the Cape Fear River from the plant's wastewater.[12] Like other PFAs, GenX does not easily break down and can accumulate in the environment.[11] Because of this quality, GenX can cause problems for both people and wildlife.

Since Chemours’ wastewater was being put into the Cape Fear River, this poses a drinking water issue for residents of the Fayetteville area as well as people further down the river. Several groundwater wells in Fayetteville had detections of GenX.[13] At the mouth of the river, the city of Wilmington uses the Cape Fear as a drinking water source. Blood samples of a group of Wilmington residents showed detections of GenX.[14]

In several studies, GenX has been shown to affect wildlife. PFAs were detected in striped bass caught from the Cape Fear, and the chemical affected the liver and immune system.[15] In plants, GenX reduced the biomass and bioaccumulated in the organism. This bioaccumulation did differ between species.[16]

In a study done to test the ability of retention and how could the GenX chemical be transported in porous materials, results showed that for different forms of the GenX chemical the absorption rate was higher. This research is important to help future researchers understand the tendencies of this chemical. Contaminated sites should be inspected from the water to the soil due to the ability of GenX to travel/transport through porous material such as soil.[17]

The lack of information on the GenX chemical in North Carolina has led to the gap of knowledge about ways in which people may be exposed to these chemicals other than drinking water. Information is also limited on the health effects caused by the GenX chemical, little experiments on animals show liver damage, pancreas damage, etc. There are no federal guidelines regarding the GenX chemical. However, the North Carolina Department of Health and Human Services has set a “health goal”, a non-regulated, and non-enforceable low contamination level where no side effects, over time, would be expected.[18]

There is little known information about the effectiveness of GenX and PFEA removal from contaminated waters, methods like, ozonation and bio-filtration. Carbon in various forms can be used to treat water that has been contaminated. Experiments done with this technique showed that shorter PFAs did not absorb.[19]
