Is it safe to drink tap water in North Carolina?

Overview of North Carolina’s drinking water quality

North Carolina’s drinking water quality has raised concerns among residents and officials. Contaminants like 1,4-dioxane and PFAS threaten public health. Despite strict north carolina water regulations and advanced testing, ensuring safe water remains a challenge.

Recent studies have highlighted the extent of the problem. At least 2.5 million North Carolinians face contaminated drinking water due to PFAS. The Environmental Working Group (EWG) found many municipal water systems exceeding new EPA limits. For instance, the Robeson County Water System, serving 64,000, has PFOS and GenX levels above new standards.

Industrial activities are a major source of contamination. North Carolina has 736 suspected industrial PFAS dischargers. This includes 66 electroplating facilities and 50 chemical manufacturers. The state has also faced repeated 1,4-dioxane contamination, impacting communities like Pittsboro.

The North Carolina Environmental Management Commission (EMC) will meet on July 10, 2024, to discuss PFAS regulations. Delays in rulemaking were due to opposition from the NC Chamber. The state budget allocates millions for PFAS cleanup and regulation. Yet, more efforts are needed to guarantee safe drinking water for all, including enhanced well water testing and stricter north carolina water regulations.

EPA pressures North Carolina to restore limits on 1,4-dioxane discharges

The Environmental Protection Agency (EPA) is urging North Carolina to reinstate strict limits on 1,4-dioxane discharges in wastewater. This probable carcinogen poses a threat to the drinking water of nearly 1 million residents. The EPA has formally objected to North Carolina’s proposed wastewater discharge permit for Asheboro, citing inadequate controls on 1,4-dioxane.

Under current EPA regulations, the agency demands that North Carolina restore stringent effluent limits on 1,4-dioxane discharges. Failure to comply within 90 days could result in federal intervention. The EPA’s action highlights the severity of the issue and the urgent need to protect public health and ensure safe drinking water for affected communities.

1,4-Dioxane Threatens Drinking Water for Nearly 1 Million NC Residents

Recent data reveals the extent of the 1,4-dioxane problem in North Carolina:

• Nearly 1 million residents are threatened by toxic 1,4-dioxane discharges in their drinking water.
• At least 2.5 million North Carolinians have drinking water contaminated with PFAS (per- and polyfluoroalkyl substances).
• Some public drinking water systems in the state are experiencing PFAS levels above the EPA’s new standards.

EPA Objects to North Carolina’s Proposed Wastewater Discharge Permit for Asheboro

The EPA’s formal objection to North Carolina’s proposed wastewater discharge permit for Asheboro sends a clear message that the state must take action to protect its residents. The agency argues that the permit lacks sufficient controls on 1,4-dioxane discharges, which could have severe consequences for public health and the environment.

EPA Demands Reinstatement of Strict Effluent Limits

To address the 1,4-dioxane crisis, the EPA is demanding that North Carolina reinstate strict effluent limits on the chemical’s discharges. These limits are critical for ensuring that wastewater treatment plants effectively remove 1,4-dioxane before releasing treated water into rivers and streams that serve as drinking water sources. By enforcing these EPA regulations, the state can take a significant step towards safeguarding its residents’ health and well-being.

Persistent issues with 1,4-dioxane in North Carolina’s waterways

The Haw and Deep Rivers in North Carolina face persistent contamination by 1,4-dioxane. This poses a significant threat to the drinking water of nearly one million residents. Communities like Pittsboro, Sanford, Fayetteville, and Wilmington are most affected. Pittsboro, in particular, has seen repeated contamination, with 1,4-dioxane levels exceeding the EPA’s health advisory limits.

In Burlington, a discharge event revealed 1,4-dioxane levels 1,300 times higher than EPA guidelines. This highlights the urgent need for effective measures to address the contamination crisis and protect public health.

Impact on downstream communities

The Haw River and Deep River are vital sources of drinking water for many in North Carolina. The table below shows the affected communities and the number of residents at risk due to 1,4-dioxane contamination:

Regulatory challenges and environmental concerns

The fight against 1,4-dioxane contamination in North Carolina’s waterways is complicated by regulatory challenges. A controversial ruling in September 2024 stripped the state’s Department of Environmental Quality (DEQ) of its authority to impose limits on 1,4-dioxane in Asheboro’s wastewater permit. This leaves downstream communities vulnerable to the harmful effects of this chemical.

Environmental advocates argue that this decision undermines critical water quality protections. It highlights the ongoing regulatory battle to safeguard public health. The EPA has given the DEQ a 90-day deadline to comply with reinstated effluent limits. Failure to act could lead to federal intervention. As communities downstream scramble to mitigate the impacts, a proactive approach is needed to address this issue and protect North Carolina’s water resources.

Identification of Apollo Chemical as the source of 1,4-dioxane discharge

Officials have pinpointed Apollo Chemical as the main culprit behind the high levels of industrial pollutant 1,4-dioxane in North Carolina’s water. This discovery followed an extensive probe into the discharge from Burlington’s wastewater plant. It led to Pittsboro’s drinking water showing 1,300 times more 1,4-dioxane than the EPA’s safety threshold.

The contamination’s effects are vast, with nearly 1 million North Carolinians possibly drinking water with unsafe 1,4-dioxane levels. Water tests in the affected zones showed about 25% of samples contained detectable amounts of the pollutant. The highest concentration was 0.5 parts per billion, exceeding the EPA’s advisory level of 0.35 ppb.

The fallout from this contamination is dire, with 1,4-dioxane staying in groundwater for decades. This makes cleanup efforts even more daunting. Costs for cleaning up contaminated sites can soar past $1 million, depending on the extent of pollution. Long-term exposure to this substance may also raise health risks, including cancer.

North Carolina is now facing the consequences of Apollo Chemical’s actions. State lawmakers have upped funding for water quality testing and cleanup to over $5 million in the last fiscal year. Yet, the journey to providing safe drinking water for everyone is far from over. Communities like Pittsboro are struggling with the environmental disaster left behind.

Pittsboro’s response to contamination events

The town of Pittsboro, North Carolina, has encountered numerous challenges due to 1,4-dioxane in its primary water source, the Haw River. High levels of this contaminant occur several times a year. This necessitates immediate action from local officials to safeguard residents’ health and safety.

Pittsboro has adopted a dual strategy to address the 1,4-dioxane issue in its water supply. First, it offers free reverse osmosis-treated water at the Chatham Marketplace. This service is provided about four times annually. It ensures residents have access to clean drinking water during contamination peaks.

Implementing Conservation Measures

The second part of Pittsboro’s strategy involves water conservation measures. These measures aim to lessen the load on the town’s water treatment systems during contamination. By promoting water-saving habits among residents, the town seeks to decrease the volume of contaminated water that must be treated.

Despite these efforts, Pittsboro faces ongoing challenges in tackling the contamination’s root cause. The town’s activated charcoal filter, with a 1 million gallon capacity, fails to remove 1,4-dioxane. This has led to a class action lawsuit against Apollo Chemicals, the entity responsible for the contamination in the Haw River.

Haw Riverkeeper pushes for stricter regulations and better oversight

Emily Sutton, the Haw Riverkeeper with the Haw River Assembly, is leading the charge for stricter regulations and enhanced oversight of industrial dischargers. Her goal is to safeguard the public’s right to access safe, clean water. With nearly 1 million North Carolina residents at risk due to 1,4-dioxane contamination in their drinking water, Sutton emphasizes the need for immediate action.

In Pittsboro, the levels of 1,4-dioxane have exceeded federal health advisory limits significantly. A discharge from Burlington’s wastewater treatment plant in September 2023 saw 1,4-dioxane levels 1,300 times higher than EPA guidelines. This incident underlines the critical need for enhanced oversight of industrial dischargers to prevent future contamination.

The EPA has set a 90-day deadline for North Carolina to meet strict effluent limits on 1,4-dioxane discharges. Yet, a ruling in September 2024 by the Chief Administrative Law Judge stripped the North Carolina Department of Environmental Quality (DEQ) of its authority to enforce limits on 1,4-dioxane in Asheboro’s wastewater permit. This decision has left communities vulnerable, and Haw Riverkeeper Emily Sutton is fighting to restore the DEQ’s regulatory power over industrial dischargers.

Despite the phased limits introduced in 2023 to give industrial sources time to reduce their 1,4-dioxane emissions, communities downstream, including Pittsboro, have faced multiple contamination events in the past year. Sutton and environmental advocates are urging for more stringent measures to protect North Carolina’s residents’ health and safety.

Controversial ruling strips DEQ of authority to impose limits on 1,4-dioxane

A September 2024 ruling by Chief Administrative Law Judge Donald van der Vaart has removed the North Carolina Department of Environmental Quality (DEQ) from setting limits on 1,4-dioxane in Asheboro’s wastewater permit. This move follows a challenge by Asheboro, Greensboro, and Reidsville against the state’s 1,4-dioxane restrictions.

Environmental advocates claim this administrative law judge ruling puts downstream communities at risk of 1,4-dioxane contamination. This chemical, a persistent pollutant, has been found in the Haw and Deep Rivers. These rivers supply drinking water to nearly one million North Carolinians. The ruling hampers the DEQ’s authority to safeguard public health and the environment.

The decision’s impact on downstream communities is significant, with Pittsboro being a prime example. This area has faced repeated contamination due to 1,4-dioxane discharges from upstream industries. Water tests show levels of the chemical exceeding federal health advisory limits, sparking concerns about long-term health impacts on residents.

With the DEQ’s authority curtailed, the state’s response to 1,4-dioxane contamination in waterways is uncertain. Environmental groups demand immediate action to reinstate the agency’s authority. They advocate for strict effluent limits to protect public health and the environment.

Cities Challenge State’s Restrictions on 1,4-Dioxane

The cities of Asheboro, Greensboro, and Reidsville have filed a lawsuit against the state’s 1,4-dioxane discharge limits. They contend these limits are too stringent and economically burdensome. These cities host industrial facilities that contribute to 1,4-dioxane in the state’s waterways.

Environmental Advocates Warn of Vulnerability for Downstream Communities

Environmental groups, including the Haw Riverkeeper and the Southern Environmental Law Center, are deeply concerned about the ruling. They fear that without the DEQ’s authority to regulate 1,4-dioxane, downstream communities like Pittsboro will continue to face contamination risks. This could lead to serious health issues due to exposure to the toxic chemical.

Southern Environmental Law Center criticizes cities for attacking clean water laws

The Southern Environmental Law Center (SELC) has voiced strong criticism against Asheboro, Greensboro, and Reidsville. These cities are trying to weaken clean water laws, which protect the right to safe drinking water. Kelly Moser, a senior attorney at the SELC, believes these cities should focus on reducing industrial pollution, not attacking environmental regulations.

Moser pointed out that the cities’ actions put nearly one million North Carolina residents at risk. They rely on the Haw and Deep Rivers for their drinking water. By challenging state restrictions on 1,4-dioxane discharges, these cities are leaving vulnerable communities exposed to harmful contaminants.

"Instead of using their power to control industrial pollution, these cities are attacking laws that protect the basic right to clean drinking water," Moser stated in a press release. "It is unconscionable that they would prioritize the interests of polluters over the health and safety of their own citizens."

The SELC has been leading the fight to restore strict limits on 1,4-dioxane discharges in North Carolina. They urge the Environmental Protection Agency (EPA) to step in. The EPA should push the state’s Department of Environmental Quality (DEQ) to reinstate water quality-based effluent limits. This would give industrial sources time to reduce their toxic chemical emissions.

Moser and the SELC believe clean water laws are vital for public health and environmental protection. They call on the cities to rethink their stance. They should work with environmental advocates to find solutions that benefit North Carolina’s communities and waterways.

EPA pushes DEQ to restore water quality-based effluent limits

The Environmental Protection Agency (EPA) is urging the North Carolina Department of Environmental Quality (DEQ) to reinstate water quality-based effluent limits for 1,4-dioxane discharges into the Cape Fear River. These limits, set in 2023, were designed to safeguard the drinking water of nearly 1 million people. The EPA’s push follows recent findings of 1,4-dioxane levels far exceeding the federal health advisory level of 35 parts per billion. This was reported by Coastal Review.

The EPA, with a budget of $9.56 billion and 16,204 full-time employees in 2023, has a long history of environmental and public health protection. Established in 1970, it has grown from a $1.4 billion budget and 5,800 staff to its current size. Today, over 50% of EPA employees are engineers, scientists, and environmental specialists, showing the agency’s dedication to science-based decisions.

Phased Limits Allow Time for Industrial Sources to Reduce 1,4-Dioxane Contributions

The proposed phased limits aim to give industrial sources, like the Apollo Chemical plant in Asheboro, more time to cut their 1,4-dioxane emissions. This approach aims to balance the urgency of protecting public health with the practical hurdles faced by industries in adopting new technologies and processes.

The EPA’s efforts to reinstate water quality-based effluent limits in North Carolina underscore its ongoing commitment to protecting the nation’s water resources. With 90% of the U.S. population relying on public water systems regulated by the Safe Drinking Water Act, the EPA is essential in ensuring access to clean drinking water for millions.

DEQ acknowledges receipt of EPA letter and reviews the objections

The North Carolina Department of Environmental Quality (DEQ) has confirmed receipt of a letter from the U.S. Environmental Protection Agency (EPA). This letter concerns objections to the proposed wastewater discharge permit for Asheboro. The DEQ is now reviewing the EPA objections. It aims to determine the best response and next steps regarding the 1,4-dioxane contamination issue. This issue poses a threat to the drinking water of nearly 1 million North Carolina residents.

In August 2023, the DEQ issued a National Pollutant Discharge Elimination System (NPDES) permit. This permit set limits on the release of 1,4-dioxane from Asheboro’s wastewater treatment plant. Yet, the EPA has raised objections to this permit. They argue it does not adequately protect public health and the environment. The EPA‘s letter also states that a public hearing on the permit objections must be requested within 90 days of receipt.

The DEQ has until mid-April to submit a revised permit addressing the EPA’s objections. If a public hearing is not requested and the DEQ fails to submit a revised permit within the 90-day timeframe, the exclusive authority to issue the permit will pass to the EPA. As the DEQ formulates its response to the EPA’s letter, it must carefully consider the objections raised. It must also consider the implications for the permit review process.

Balancing industrial activity with the health and safety of North Carolina’s water resources

North Carolina must navigate the delicate balance between industrial growth and safeguarding its water resources and public health. The state boasts 1,980 community water systems and 3,092 non-community systems, serving a large segment of its population. Yet, contaminants like 1,4-dioxane, PFAS, nitrates, and hexavalent chromium threaten the health of its residents.

Industrial discharges, agricultural runoff, and natural geological deposits are major contributors to water contamination. The EPA has set Maximum Contaminant Levels (MCLs) for various chemical compounds affecting drinking water safety. The compliance rates of water systems are evaluated through MCL and monitoring violations, as seen in the table below:

Ensuring compliance with water quality standards is a daunting task, given the complexity of contaminant-specific regulations. The state grapples with regional challenges, including PFAS contamination in the Cape Fear River Basin, high nitrate levels from agricultural runoff, and industrial pollution in the Piedmont region.

To safeguard North Carolina’s water resources and public health, a holistic strategy is imperative. This entails stricter regulations on industrial discharges, enhanced monitoring and oversight, and investment in water treatment infrastructure. Local water testing services are vital in identifying specific contaminants, enabling communities to implement necessary mitigation strategies. By focusing on water resource protection and public health, North Carolina can achieve a harmonious balance between industrial development and the well-being of its citizens.
