Is North Carolina tap water safe to drink?

Overview of North Carolina’s Tap Water Quality

North Carolina’s tap water quality is generally safe, thanks to state efforts and water utilities. Yet, concerns about contaminants and impurities in water sources persist among residents.

A contaminant is any substance in water not a water molecule itself. Some contaminants, like chlorine, are added to ensure safe drinking water. Others can be harmful, depending on the substance and quantity.

To address these concerns, North Carolina has conducted voluntary monitoring of its drinking water systems. In 2019, Hendersonville participated in a state-wide testing event for PFAS. This event was facilitated by Duke University, the University of North Carolina at Chapel Hill, and NC State University. The results showed PFAS was not detected in Hendersonville’s drinking water supply during the testing period.

Yet, samples collected on the French Broad River, upstream of Hendersonville’s new water source, found PFAS at levels well below the EPA’s new drinking water standards. The city is constructing a fourth water source on the French Broad River to ensure drought resiliency and meet future community water needs.

In the Cape Fear watershed, nonpoint source pollution accounts for 90% of pollution during normal flows and flooding conditions. During drought years, point sources like wastewater treatment plants significantly increase in-stream pollution. Research indicates that 16% of the Cape Fear watershed is responsible for the majority of pollutants across all flow conditions.

The Nature Conservancy has used the Soil and Water Assessment Tool (SWAT) model to identify priority areas for conservation and restoration. This model analyzes weather data from 1979 to 2019 to determine pollution sources. The organization has shared this modeling data with other land trust organizations and government agencies to guide future restoration efforts in the Cape Fear River basin.

North Carolina regularly monitors its groundwater resources, with 257 groundwater reports available. These reports include annual assessments from the North Carolina Ground Water Resources Monitoring Well Network. They cover various regions and counties throughout the state. The reports detail groundwater quality, including contaminants like arsenic, radon, and metals.

By continuously monitoring and addressing contaminants in both surface water and groundwater sources, North Carolina aims to ensure safe and high-quality tap water for its residents. As new challenges arise, such as the presence of PFAS, the state and its water utilities remain committed to implementing effective water treatment solutions to protect public health.

PFAS Contamination in North Carolina’s Drinking Water

North Carolina’s drinking water is under threat from per- and polyfluoroalkyl substances (PFAS), a group of highly toxic and persistent chemicals. These forever chemicals have been found in the water systems of millions of residents across the state. This raises serious concerns about the health risks linked to exposure to these toxic fluorinated chemicals.

What are PFAS?

PFAS are synthetic chemicals used in various industrial processes and consumer products for their water-resistant and non-stick properties. Two extensively studied PFAS are perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). They have been linked to numerous adverse health effects. These forever chemicals persist in the environment and accumulate in the human body, leading to increased health risks.

Health Risks Associated with PFAS Exposure

Exposure to PFAS is linked to serious health problems, including:

• Increased risk of certain types of cancer, such as kidney and testicular cancer
• Impaired immune system response
• Liver and kidney damage
• Hormonal disruption
• Developmental and reproductive issues

The extent of PFAS contamination in North Carolina’s drinking water is alarming. At least 2.5 million North Carolinians have drinking water contaminated with these toxic fluorinated chemicals. The drinking water crisis in North Carolina has been largely ignored, despite evidence linking PFAS exposure to severe health risks.

Here are some key statistics highlighting the problem’s scope:

As North Carolina faces this public health crisis, it’s vital for residents to understand the health risks of PFAS exposure. Advocating for strict regulations is essential to protect drinking water from these toxic fluorinated chemicals. Only through collective efforts by policymakers, industry, and the public can we address this issue and safeguard North Carolinians’ health for future generations.

EPA’s New Drinking Water Standards for PFAS

The U.S. Environmental Protection Agency (EPA) has set new drinking water standards for six per- and polyfluoroalkyl substances (PFAS). These standards, known as Maximum Contaminant Levels (MCLs), aim to reduce PFAS exposure for approximately 100 million people across the United States. This is the first time enforceable limits have been established for these substances.

Maximum Contaminant Levels (MCLs) for PFAS

The EPA has established the following MCLs for six PFAS chemicals:

• PFOA: 4.0 parts per trillion (ppt)
• PFOS: 4.0 ppt
• GenX chemicals: 10 ppt
• PFNA: 10 ppt
• PFHxS: 10 ppt

These limits range from 4 to 10 parts per trillion (ppt). This reflects the EPA’s commitment to ensuring safe drinking water for all Americans. PFAS chemicals, known as "forever chemicals," have been used for decades and persist in the environment.

Impact of New Standards on North Carolina Water Utilities

In North Carolina, the new EPA drinking water standards have a significant impact. Over 300 water systems in the state have PFAS levels exceeding the new standards. This includes 42 municipal water systems serving nearly 3 million residents combined. Approximately 20% of small public water systems tested in North Carolina also exceed the new PFAS standards.

To address this issue, water utilities in North Carolina will need to take action. They will have to reduce PFAS levels in their drinking water. Public water systems across the U.S. have three years to determine PFAS levels and an additional two years to implement PFAS treatment measures. The deadline is set for 2029. The estimated annual cost for implementing the new PFAS rule is about $1.5 billion.

Federal funding is available to support these efforts. $1 billion has been allocated for initial testing and treatment at public water systems and homes with privately owned wells, sourced from the Bipartisan Infrastructure Law. The EPA expects that excess PFAS levels will be found in approximately 6-10% of water systems in the U.S. This could affect around 100 million people.

As North Carolina water utilities work to comply with the new EPA drinking water standards, residents can expect to see increased efforts. These efforts will be to monitor and reduce PFAS levels in their tap water. This will help ensure that all North Carolinians have access to safe, clean drinking water, free from harmful PFAS contamination.

Largest North Carolina Water Utilities with PFAS Detections Above EPA MCLs

Several major water utilities in North Carolina face a significant challenge. They must deal with PFAS contamination levels that surpass the Environmental Protection Agency’s (EPA) new maximum contaminant levels (MCLs). These utilities, serving millions, must act swiftly to provide clean drinking water to their communities.

The Piedmont Triad Regional Water Authority, City of Durham, City of Greensboro, Fayetteville Public Works Commission, and Brunswick County Public Utilities are among the most affected. To comply with the EPA’s new standards, they will need to install advanced filtration systems. This includes reverse osmosis or granular-activated carbon, and possibly expanding their facilities.

The EPA has set new MCLs for various PFAS compounds:

• GenX chemicals: 10 parts per trillion (ppt)
• PFOA: 4 ppt
• PFOS: 4 ppt
• PFNA: 10 ppt
• PFHxS: 10 ppt

Public water systems have five years to meet these new standards. The North Carolina Department of Environmental Quality (DEQ) is actively sampling water systems. In 2023, they sampled over 530 small public water systems. Late 2022 saw sampling at 50 municipal and county systems.

The sampling results are alarming. About 42 municipal water systems and 270 small systems have detected PFAS above the new MCLs. This means around 3 million North Carolina residents are served by water that doesn’t meet the EPA’s updated PFAS standards. This highlights the urgent need for utilities to invest in effective treatment solutions.

Communities Suffering from PFAS Pollution in North Carolina

North Carolina’s communities face severe PFAS pollution issues, mainly from industrial sources. The Lower Cape Fear region is most affected, with residents exposed to harmful PFAS compounds for decades. This has caused significant health concerns.

The Fayetteville Works facility, once DuPont’s and now Chemours’, is a major polluter. It discharges PFAS into the Cape Fear River, impacting Wilmington and Brunswick County. The Cape Fear Public Utility Authority has spent $54 million on a filtration system. This has led to an 8% rate increase, adding $5.40 to monthly bills.

Lower Cape Fear Region

The Lower Cape Fear region is severely impacted by PFAS pollution. Wilmington and Brunswick County are among the hardest hit. Brunswick County’s Northwest Water Treatment Plant has had to invest in a reverse osmosis system, costing $167.3 million. Despite these efforts, PFAS levels in water from Fayetteville Public Works and Lumberton exceed federal limits by 445% and 650%, respectively.

Pittsboro and Burlington

Pittsboro and Burlington also face PFAS contamination issues. High PFAS levels have been found in their drinking water and wastewater. Elevate Textiles is identified as a major contributor to PFAS in Burlington’s water. Local governments have spent millions on filtering PFAS from drinking water, as required by law.

Regulatory action on PFAS pollution has been slow. The North Carolina Department of Environmental Quality (NCDEQ) has been criticized for not enforcing PFAS emissions standards. A recent draft permit for Lear Corporation allows unrestricted PFAS releases into the Cape Fear River. It only requires the company to study existing pollution, not impose emissions limits.

As communities continue to suffer, it’s critical for regulatory agencies to act. The crisis in North Carolina highlights the need for stronger regulations and enforcement. This is essential to protect public health and the environment.

Industrial Sources of PFAS Contamination in North Carolina

North Carolina harbors numerous industrial facilities, posing a significant risk to its drinking water. Data reveals at least 66 electroplating facilities and 50 chemical manufacturers within the state. These entities could be contributing to the presence of harmful PFAS chemicals in the water. The state has identified 736 suspected industrial PFAS dischargers, showing widespread contamination sources.

Activities like the use of firefighting foam near military bases and airports, wastewater sludge spreading, and textile manufacturing also contribute to PFAS pollution. The broad scope of these contaminants emphasizes the necessity for thorough monitoring and regulation of industrial dischargers. This is essential for safeguarding public health and the environment.

The effects of industrial PFAS contamination are seen in communities statewide. For instance, the Cape Fear Public Utility Authority (CFPUA) serves nearly 74,000 individual accounts and about 200,000 customers. It invested $54 million in a granular activated carbon filtration system, operational in 2022. The system’s operational costs are expected to be nearly $4 million in the first year, rising to at least $5 million annually thereafter. This financial strain is a direct consequence of addressing PFAS contamination from industrial activities.

To tackle PFAS contamination, it is imperative that regulatory bodies and industrial entities collaborate. Implementing stricter regulations, monitoring, and enforcement is vital. This will help ensure North Carolina’s residents have access to safe, clean drinking water.

Military Base Contamination and PFAS in North Carolina

In North Carolina, military bases are major sources of PFAS contamination in drinking water and groundwater. The Department of Defense has confirmed PFAS presence in drinking water, groundwater, or both at ten installations across the state. Recent EPA data shows that military bases are a primary source of PFAS contamination affecting millions of Americans nationwide.

Marine Corps Base Camp Lejeune is one of the most severely impacted sites. Drinking water there is highly contaminated with PFAS and other chemicals. The contamination occurred from the 1950s through the 1980s, exposing Veterans and their families to harmful levels of PFAS. The Camp Lejeune Families Act of 2012 offers cost-free health care for Veterans who served at the base for at least 30 days between August 1, 1953, and December 31, 1987, and suffer from any of the 16 specified medical conditions.

Seymour Johnson Air Force Base is also affected. Private drinking water wells off base have been contaminated with PFAS levels exceeding the new EPA maximum contaminant levels (MCLs). The EPA’s recently announced standards limit six PFAS in drinking water, with MCLs of 4 parts per trillion (ppt) for PFOA and PFOS, and 10 ppt for GenX, PFNA, and PFHxS.

The widespread PFAS contamination from military bases has led to costly remediation efforts for local water utilities. An estimated 50% of water systems with high PFAS levels will require corrective action to meet the new federal standards. As the Department of Defense works to address the contamination and transition to PFAS-free alternatives, affected communities continue to grapple with the health risks associated with exposure to these persistent chemicals.

Health Consequences of PFAS Exposure in North Carolina

The PFAS contamination crisis in North Carolina has sparked widespread concern. Over 14,000 man-made PFAS chemicals have been used in various processes, contaminating the environment for decades. The state must address the health impacts on residents, animals, and wildlife.

Increased Risk of Chronic Diseases

A study by N.C. State University analyzed 344 blood samples from Wilmington residents. It found a link between PFAS exposure and chronic diseases. Those with higher PFAS levels were at greater risk for high cholesterol, high blood pressure, and heart disease. This highlights the need for immediate action to protect public health.

The North Carolina Department of Environmental Quality (DEQ) estimates that setting surface water standards for PFAS could prevent up to 9,000 cancer-related deaths. This statistic emphasizes the severity of the PFAS crisis. It also stresses the importance of strict regulations to protect residents’ health.

Impact on Animals and Wildlife

PFAS contamination affects not just humans but also animals and wildlife in North Carolina. Studies have found high PFAS levels in horses and dogs near the Chemours Fayetteville Works facility. This raises concerns about their long-term health. Research also shows PFAS exposure harms the immune systems of alligators in the Cape Fear River watershed, highlighting ecological consequences.

To tackle the PFAS crisis, North Carolina has allocated $50 million to research. This is the largest investment by any state legislature in the U.S. Yet, with millions exposed to PFAS in their drinking water, ensuring safe water remains a daunting task.

Identifying New PFAS in North Carolina’s Water

Researchers from the University of North Carolina and North Carolina State University have made a groundbreaking discovery. They identified 11 new PFAS compounds in the water downstream of the Chemours plant. This is a significant step in the fight against water contamination caused by per- and polyfluoroalkyl substances (PFAS).

The detection of these previously unknown PFAS compounds highlights the need for stricter regulations. With over 10,000 different PFAS chemicals, including harmful PFOA and PFOS, the Environmental Protection Agency (EPA) estimates that 6% to 10% of US public drinking water systems are contaminated. This contamination poses serious health risks.

The Chemours plant, along with its predecessor DuPont, has a long history of manufacturing PFAS chemicals. This has led to significant contamination in the Cape Fear River. Drinking water in this region often contains PFAS levels many times higher than the federal limit. This poses serious health risks to residents, including an increased likelihood of developing certain cancers.

The EPA has taken steps to address the growing concern over PFAS contamination. They have proposed enforceable limits for several PFAS compounds in drinking water. The finalized limits, set to take effect in April 2024, include stringent standards for PFOA, PFOS, PFNA, PFHxS, and HFPO-DA (GenX). These new regulations are expected to drive the implementation of advanced water treatment technologies. This will ultimately improve the safety of North Carolina’s tap water.

Residents’ Efforts to Ensure Safe Drinking Water in North Carolina

North Carolina residents are taking proactive steps to ensure their families have safe drinking water. Groups like Clean Cape Fear are leading the charge, organizing efforts to hold polluters accountable. This is in response to the widespread PFAS contamination affecting millions.

Many residents have turned to in-home filtration systems to protect themselves. These systems, such as reverse osmosis and activated carbon filters, are effective in reducing PFAS levels. They serve as a temporary solution until more extensive measures are implemented.

Community advocacy has been instrumental in pushing for safer drinking water standards. Clean Cape Fear and similar groups have organized rallies and campaigns. Their efforts have led to stricter regulations and increased funding for water infrastructure projects.

The North Carolina government has also stepped up to address the issue. Over $265 million has been allocated for 99 drinking water and wastewater projects. This funding will support various initiatives, including lead and copper line replacements and PFAS removal facilities.

As North Carolina faces the challenges of PFAS contamination, the efforts of residents, advocates, and government officials are critical. Through collaboration, education, and investment in water infrastructure, the state can protect public health and restore trust in its tap water.

Effectiveness of In-Home Drinking Water Filters for Reducing PFAS

In North Carolina, growing concerns about PFAS contamination in tap water have prompted residents to seek in-home drinking water filters for protection. With nearly 50% of Americans consuming water with PFAS levels above advisory limits, finding effective filtration solutions is now a top priority.

Researchers at Duke and North Carolina State University have studied various in-home drinking water filters’ effectiveness in reducing PFAS. Their findings indicate that multistage carbon filters and reverse osmosis filters are the most efficient. These filters have shown impressive results:

The Environmental Working Group (EWG) conducted a study testing for 25 individual PFAS chemicals. This study further confirmed the effectiveness of certain carbon-based pitcher filters in reducing PFAS in tap water. Brands like AquaTru and Clearly Filtered have been recommended by Mamavation for their outstanding performance in PFAS removal.

While reverse osmosis filters are the most effective for PFAS reduction, they typically cost around $200 and require replacement every five years. Carbon filters, on the other hand, need to be replaced every six months. As residents navigate the challenges of PFAS contamination, investing in reliable in-home drinking water filters can provide peace of mind and protect their health.

How the EPA’s New MCLs Will Improve North Carolina’s Tap Water Quality

The Environmental Protection Agency (EPA) has set the first national drinking water standards for PFAS. These new Maximum Contaminant Levels (MCLs) will greatly enhance tap water quality in North Carolina and the U.S. Public water systems must meet these MCLs by 2029. They must also start monitoring PFAS in drinking water by 2027.

North Carolina will receive $29 million to help utilities meet the new EPA standards. The state’s Department of Environmental Quality has been working with water systems to test for PFAS. This effort aims to ensure a smooth transition to better drinking water for North Carolina residents.

Successful Examples of PFAS Treatment in North Carolina

Several North Carolina water utilities have already tackled PFAS contamination. For example, the Cape Fear Public Utility Authority has spent over $40 million on filters. This has significantly reduced PFAS in the Lower Cape Fear region’s drinking water.

The Town of Maysville has also successfully addressed PFAS contamination. By using effective treatment and strict monitoring, Maysville has shown that PFAS treatment is feasible in North Carolina. These examples offer a roadmap for other utilities to improve tap water quality.

Additional Benefits of PFAS Treatment

PFAS treatment methods also reduce other contaminants. This includes disinfection byproducts and volatile organic compounds. This approach not only tackles PFAS but also improves overall tap water safety and purity in North Carolina.

By focusing on PFAS, North Carolina’s water utilities can also reduce other contaminants. This will provide safer drinking water for residents. The EPA’s new MCLs are driving a broader improvement in water quality, benefiting public health and the environment.

Steps Residents Can Take to Address PFAS Contamination

Concerns about drinking water contamination from PFAS are escalating in North Carolina. Residents can take steps to protect their water. The new drinking water standards address PFAS in public systems. Yet, homes on private wells are not covered.

For those with private wells in areas with suspected PFAS contamination, testing is essential. The Bipartisan Infrastructure Law provides $1 billion to help well owners test for and address PFAS. This funding supports homeowners in identifying risks and taking action.

Residents can also take several steps to ensure their drinking water is safe:

• Consult EWG’s interactive map and Tap Water Database to learn about PFAS in their area.
• Invest in in-home filters, like reverse osmosis or granular-activated carbon systems, to reduce PFAS levels.
• Stay updated on PFAS research and advocate for stricter standards and transparency from utilities and agencies.

By proactively addressing PFAS testing and mitigation, North Carolina residents can protect their health and communities. As the state faces PFAS challenges, individual efforts and support from the Bipartisan Infrastructure Law are key. Together, they ensure safe drinking water for everyone.

North Carolina Tap Water Quality: A Comprehensive Overview

Tap water quality in North Carolina has become a pressing issue, with concerns over PFAS contamination, high nitrate levels, and the presence of heavy metals. The Cape Fear River Basin has been severely impacted by industrial discharges, leading to widespread PFAS contamination. Agricultural runoff and CAFOs have also raised nitrate levels in water, posing health risks to those who rely on it for drinking.

The EPA’s new PFAS standards aim to improve water quality for millions, including those in North Carolina. These standards will require water utilities to use advanced treatments to remove PFAS and other harmful substances. While this is a major step towards safer drinking water, residents can also take steps to protect themselves. Using in-home water filtration systems like reverse osmosis and activated carbon filters can help.
