What You'll Learn
Sewage spills
Septic systems, commonly used in rural areas of the Catawba basin, pose a significant risk to water quality. Improper maintenance, aging tanks, and leaks contribute to sewage pollution in the river. This issue is particularly prominent in the Upstate region.
Fertilizers, pesticides, and other chemicals used in agriculture and home or road construction also contribute to water pollution. Excess chemicals can easily enter storm drains, and rainfall washes them into rivers and streams. Additionally, pet waste left in yards can wash into storm drains, introducing bacteria into the water.
The Catawba River, named after the Catawba tribe of Indigenous People or "the people of the river," spans over 200 miles across two states, North Carolina and South Carolina. The river has historically faced pollution threats from coal ash and textile mill dyes. With a growing population in the basin, rapid development, and poor water management, the Catawba River continues to face environmental challenges.

Coal ash pollution
The Catawba River, which spans over 200 miles across two states, is threatened by pollution from coal ash and other sources. Coal ash, a toxic byproduct of power generation, has historically been a significant pollutant of the river and local water supply. Duke Energy, the largest electric power company in the U.S., has been at the centre of a years-long legal battle over its responsibility for coal ash pollution and the subsequent cleanup efforts.
In 2012, the Catawba Riverkeeper Foundation, a small nonprofit organisation, began leading the charge against Duke Energy and other large companies, fighting for them to take responsibility for the cleanup of coal ash from their sites. Water sampling by the Catawba Riverkeeper in 2012 revealed contamination and unpermitted discharges at Mountain Island Lake and Lake Wylie. This led to a lawsuit filed by the organisation in partnership with other groups against Duke Energy for violating state groundwater standards for metals associated with coal ash.
The settlement, reached in December 2019, marked the end of the legal battle and the beginning of the largest environmental cleanup in United States history. The state-ordered cleanup involves moving millions of tons of coal ash from open, unlined water pits to lined landfills or recycling it for beneficial use. As of 2020, the N.C. Department of Environmental Quality has approved plans for the closure and excavation of coal ash sites, with Duke Energy being ordered to clean up 7 of its 14 sites in North Carolina, including two in the Catawba Basin: the Marshall site and the Allen site.
The toxic chemicals in coal ash can seep into the groundwater and spill into lakes and rivers, threatening drinking water supplies and downstream properties. The Catawba Riverkeeper Foundation continues to work towards protecting and restoring this critical waterway, ensuring clean and plentiful water for future generations.

Poor water management
The Catawba River, a vital water source for North and South Carolina, faces significant challenges due to poor water management practices. This river, which provides drinking water for millions and supports a diverse ecosystem, has been subjected to various pollutants and mismanaged land use practices, threatening its health and sustainability.
One of the primary concerns is the impact of agricultural runoff. With intensive farming practices in the region, excessive nutrients, especially nitrogen and phosphorus, find their way into the river. These nutrients cause algae blooms, which deplete oxygen levels in the water, creating "dead zones" where aquatic life cannot survive. The excessive use of pesticides and fertilizers in agriculture further contributes to the pollution, as these chemicals contaminate the water, harming fish and other aquatic organisms.
Industrial discharge is another significant issue. Several industries, including power plants and manufacturing facilities, have released pollutants into the Catawba River over the years. These discharges contain harmful substances such as heavy metals, toxic chemicals, and pollutants like mercury and PCBs (polychlorinated biphenyls). These contaminants accumulate in the river sediment and bioaccumulate in the tissue of fish and other aquatic life, eventually making their way up the food chain and posing risks to human health.
Poor land use practices also play a role in the degradation of the Catawba River. Deforestation, urbanization, and the destruction of natural habitats have led to increased sedimentation and erosion. Clearing land for development exposes the soil to erosion, and the resulting sediment runoff clouds the water, smothering aquatic plants and harming fish spawning grounds. Moreover, improper waste disposal and sewage treatment have contributed to the river's pollution, with untreated or partially treated sewage releasing harmful bacteria, nutrients, and pathogens into the water.
The consequences of these poor water management practices are evident in the declining health of the Catawba River ecosystem. Reduced water quality affects not only the aquatic life but also the birds and wildlife that depend on the river. It also impacts recreational activities such as fishing, boating, and swimming, as well as the aesthetic value of the river and its surrounding areas. The economic implications are significant, as a polluted river can drive away tourists and reduce property values in the region.
To address these issues, a comprehensive approach to water management is necessary. This includes stricter regulations on agricultural practices, better enforcement of environmental laws pertaining to industrial discharge, and improved waste management and sewage treatment systems. Reforestation and the implementation of buffer zones can help reduce sedimentation and improve water quality. Educating the public about the importance of responsible land and water use is also crucial in fostering a collective sense of stewardship for this valuable natural resource.

Agricultural chemicals
The Catawba River, which runs through North and South Carolina, has been named the most endangered river in the United States. The river and its tributaries have been heavily polluted with harmful bacteria and chemicals, including copper, phosphorous, and fecal bacteria, which have entered the river through stormwater runoff, sewage spills, and septic systems. These pollutants have put public health and aquatic life at risk, with 78 out of 127 sites monitored by the South Carolina Department of Health and Environmental Control (DHEC) failing to meet federal standards for supporting recreation or aquatic life between 2000 and 2004.
One of the major sources of pollution in the Catawba River is agricultural activities, including the use of fertilizers, pesticides, and other chemicals. While these chemicals are important for crop production, their excessive use can have detrimental effects on water quality. Rainfall and stormwater runoff can wash these chemicals into rivers and streams, leading to pollution and contamination. This is particularly true in the case of the Catawba River, where the rapid rate of growth and development in the area has increased the risk of chemical runoff into the river.
In addition to the direct impact on aquatic life, the presence of agricultural chemicals in the Catawba River can also have indirect effects on the environment. For example, sediment, which is a common pollutant in the river, can bind to and carry other pollutants, including agricultural chemicals, across the landscape and into waterways. This can result in the contamination of spawning beds and contribute to invasive weed and mosquito problems. Furthermore, the use of pesticides and fertilizers can also have long-term effects on the environment, as some of these chemicals are persistent and do not easily break down in nature.
To address the issue of agricultural chemical pollution in the Catawba River, it is important to implement proper watershed management practices. This includes identifying the sources and types of pollution, as well as recommending ways to reduce or eliminate them. Education and outreach are also crucial, as homeowners and agricultural producers play a significant role in preventing chemical runoff into the river. By working together and implementing best management practices, it is possible to reduce the impact of agricultural chemicals on the Catawba River and improve the health of this important waterway.

Sediment pollution
The Catawba River, named for the Catawba tribe of Indigenous People, "the people of the river", spans two states and more than 200 miles. The Catawba River Basin in South Carolina begins at Lake Wylie and runs downstream to Lake Wateree. The Catawba River is not among the most polluted rivers in the United States, but it is threatened by trends of development, use, and poor water management. One of the main pollutants is sewage, with Charlotte-Mecklenburg Utilities responsible for 370 raw sewage spills in 2005-2006, resulting in 330,000 gallons of sewage reaching the surface water.
Agriculture, home construction, and road construction are typical sources of sediment pollution. The rapid growth and development in the Catawba River Basin contribute to this, as erosion from cleared land sends sediment into the river. Additionally, rainwater or snowmelt runoff from developed areas can carry pollutants such as fertilizers, pesticides, and other chemicals into the river, further exacerbating the problem.
To address sediment pollution in the Catawba River Basin, watershed management is crucial. This involves identifying the different kinds of pollution and their transport mechanisms and recommending ways to reduce or eliminate them. Proper watershed management can help control pollution and protect the natural resources within the watershed. Additionally, public education is essential to reducing sedimentation. While the Sedimentation Pollution Control Act of 1973 included an initial phase of education, there is a need to repeat this practice and reach younger and unreached groups.
In summary, sediment pollution is a significant issue in the Catawba River Basin, exacerbated by human activities and development in the region. It poses a threat to water quality and the natural resources within the watershed. By implementing effective watershed management practices and educating the public, it is possible to mitigate the impacts of sediment pollution and work towards preserving and protecting this critical waterway.
