Population growth and development have caused millions of gallons of wastewater to wash into the river
Population growth and development have caused millions of gallons of wastewater to wash into the Haw River, threatening the health of the river and the ecosystem that depends on it. The Haw River, a tributary of the Cape Fear River, flows for 110 miles through North Carolina, providing drinking water and recreation for nearly a million people. The river and its surrounding areas are home to a diverse range of wildlife, including blue herons, beavers, deer, otters, and rare freshwater mussels.
However, the rapid development and population growth in the region have had detrimental effects on the river's health. Millions of gallons of wastewater and polluted runoff, caused by ageing infrastructure and increased flooding, have washed into the Haw River. This has led to a buildup of nitrogen and phosphorus, resulting in large algal blooms in Jordan Lake, a major drinking water reservoir. The pollution has also impacted the health of the people and wildlife in the area. In 2014, the Haw River was listed as one of America's most endangered rivers by American Rivers, highlighting the economic and recreational opportunities at risk due to pollution.
The state of North Carolina is required by the Clean Water Act to address the issue. However, there has been a delay in enforcing the 2009 Jordan Lake Rules, which aim to reduce polluted runoff. Disagreement between environmental groups, local governments, and economic interests has also hindered progress in improving the river's ecology. Additionally, the North Carolina Department of Environment and Natural Resources (DENR) budget for water quality protection has been significantly cut, and the state has rejected grant money intended for water quality monitoring.
Despite these challenges, efforts are being made to improve the situation. The Jordan Lake One Water (JLOW) initiative, launched in 2017, aims to bring together communities and interest groups to restore the ecological and economic health of the watershed. The Haw River Assembly is also taking action, relaunching its Muddy Water Watch project to address sediment pollution and erosion control issues. Furthermore, the conservation of the Haw River has become a focus for several groups and government agencies, with the development of trails and initiatives to preserve and protect the river.
The future of the Haw River remains uncertain, but the recognition of its fragile state and the efforts of various stakeholders provide hope for its restoration and long-term sustainability.

Suburban nutrient runoff and sediment pollution are major issues
The Haw River in North Carolina has faced significant water pollution issues due to suburban nutrient runoff and sediment pollution. With a 1700-square-mile watershed, the river provides drinking water to nearly one million residents in the surrounding cities. However, population growth, aging infrastructure, and increased development have contributed to the degradation of water quality in the river.
Suburban nutrient runoff occurs when excess nutrients from sources such as lawn fertilizers, septic systems, and livestock manure are washed into nearby waterways. In the case of the Haw River, nutrient runoff has led to excessive algae growth, known as algal blooms. These blooms block sunlight from reaching underwater vegetation and create "dead zones" with low oxygen levels, negatively impacting the health of fish, shellfish, and other aquatic life. The increase in population since the 1960s has overwhelmed the systems designed to protect the river, resulting in raw sewage spills and further contributing to nutrient runoff.
Sediment pollution, another major issue for the Haw River, is caused by soil particles detached from the land by erosion. Construction activities and stormwater runoff have increased the amount of sediment entering the river. As sediment builds up in the waterway, it reduces water clarity, blocks drainage systems, and fills channel beds, leading to habitat loss for fish and other aquatic organisms. Additionally, sediment can carry and deposit contaminants such as heavy metals, pesticides, and nutrients, further degrading water quality.
The impact of suburban nutrient runoff and sediment pollution on the Haw River has not gone unnoticed by the community. Efforts such as the Jordan Lake One Water (JLOW) initiative, launched in 2017, aim to bring together communities and interest groups to restore the ecological and economic health of the watershed. The initiative focuses on building resilience to climate change, reducing pollution, and restoring the ecosystem. Additionally, the Haw River Assembly is relaunching its Muddy Water Watch project to document and report potential sediment violations, demonstrating a commitment to addressing sediment pollution issues.
Addressing these issues is crucial for the health and well-being of the residents and the diverse wildlife that depend on the river. By implementing effective conservation practices and improving water management strategies, it is possible to reduce nutrient runoff and sediment pollution, improving the overall health of the Haw River and the surrounding ecosystem.

Industrial pollutants from cities upstream have contaminated drinking water
The Haw River in North Carolina has been the victim of heavy pollution. Population growth and development have caused millions of gallons of wastewater and polluted runoff to wash into the river. This has led to a buildup of nitrogen and phosphorus, creating large algal blooms in the Jordan Lake Reservoir, a major drinking water source for nearly one million people.
The river's health has not gone unnoticed, and in 2014, it was listed as one of America's most endangered rivers. Conservation groups and government agencies have since been working to improve the Haw River's ecology. However, there is disagreement between environmental groups, local governments, and economic interests on the best course of action.
While most sections of the river are now considered clean, the drinking water in Pittsboro, a community served by the river, was found to be contaminated by industrial pollutants from cities upstream. An investigation by the Haw River Assembly in 1985 concluded that the drinking water in Pittsboro was contaminated by pollutants from Greensboro, Reidsville, and Burlington.
More recently, in 2019, PFAS was detected in the river and Pittsboro's drinking water. PFAS levels in Pittsboro were found to be 30 times higher than in Durham. State regulators have identified wastewater treatment plants and stormwater runoff from fields where sewage sludge is applied to land as sources of PFAS contamination.
The state of North Carolina has taken steps to address the issue, with the Department of Environmental Quality ordering 25 municipalities in the Cape Fear River Basin to begin monthly monitoring for PFAS. This monitoring aims to identify the sources of contamination and work with municipalities to reduce it.

High levels of PFAS contamination have been found in the river
The Haw River, which flows 110 miles from north-central Piedmont, North Carolina, to the Cape Fear River, has been the victim of severe pollution. Population growth since the 1960s, ageing infrastructure, and increased development have all contributed to the river's pollution. While the river has faced pollution from various sources, one particular contaminant, PFAS (Perfluoroalkyl and Polyfluoroalkyl Substances), has been found in high levels.
PFAS are synthetic chemicals designed for long-term stability and are challenging to break down. They are commonly found in industrial applications, consumer goods, and even in natural environments like groundwater and surface waters. PFAS enter the Haw River through various pathways, including industrial and manufacturing processes, wastewater treatment facilities, and runoff from contaminated sites.
The impact of PFAS contamination in the Haw River is concerning due to its potential health risks. While research is ongoing, studies have linked PFAS exposure to adverse health effects, including cancers and increased cholesterol levels. PFAS have also been detected in the blood of most Americans, indicating widespread exposure. The health risks are particularly relevant to the nearly one million people who rely on the Haw River for drinking water and recreational activities.
To address the PFAS contamination, various actions have been taken. The U.S. Environmental Protection Agency (EPA) has released maximum contaminant levels (MCLs) for certain PFAS and is working to reduce PFAS exposure. Local communities and environmental groups are also engaged in conservation efforts, and the North Carolina government has implemented initiatives like the Jordan Lake One Water (JLOW) initiative to improve the river's ecology and reduce pollution.
While progress is being made, the high levels of PFAS contamination in the Haw River remain a critical issue. The persistence of PFAS in the environment and their potential health impacts underscore the importance of continued research, regulation, and collaboration among stakeholders to protect the health of the river and the people and ecosystems that depend on it.

The Haw River, a tributary of the Cape Fear River, flows 110 miles from north-central Piedmont, North Carolina, to the Cape Fear River, just below the Jordan Lake Reservoir. The river is a source of drinking water for nearly a million people and supports a diverse range of wildlife, including blue herons, beaver, deer, and more. It is also a popular destination for outdoor recreational activities such as hiking, paddling, swimming, fishing, and picnicking.
However, the Haw River has faced significant pollution issues. Population growth, aging infrastructure, and increased development have led to polluted runoff, raw sewage spills, and flooding, causing large algal blooms and impacting the health of the ecosystem and nearby communities. While efforts are being made to improve the river's ecology, there is disagreement between environmental groups, local governments, and economic interests on the best course of action.
The state of North Carolina has developed a clean-up plan for the Jordan Lake Reservoir, and initiatives like the Jordan Lake One Water (JLOW) initiative aim to restore the ecological and economic health of the watershed. However, North Carolina has also weakened clean water protections through legislative actions, creating confusion and concern about the state's ability to address water pollution effectively.
For instance, the General Assembly has systematically underfunded the Department of Environmental Quality (DEQ), leading to understaffing and a quarter of polluters operating under expired permits. Additionally, laws passed by the General Assembly have given control of important commissions to a supermajority hostile to environmental protections, blocking the development of water quality standards and allowing weak permits for fish farms and wastewater treatment plants. These actions have led to warnings from groups like the Southern Environmental Law Center, who have petitioned the Environmental Protection Agency (EPA) to intervene and protect the state's waterways.
The future of clean water protections in North Carolina remains uncertain, and it is unclear how effectively the legislature will address the issues facing the Haw River and other waterways in the state. With high levels of toxic pollutants and ongoing challenges, the legislature will need to take decisive action to protect the health and well-being of North Carolina's communities and natural environment.
