In North Carolina, small water systems are confronting a significant challenge: the rising costs associated with the removal of per- and polyfluoroalkyl substances (PFAS) from drinking water supplies. These chemicals, often referred to as “forever chemicals” due to their persistence in the environment, have become a pressing issue for utilities across the state, particularly for those drawing water from the Cape Fear River.

The Emergence of PFAS Regulations

Under new mandates from the Environmental Protection Agency (EPA), water utilities must adopt advanced technologies to effectively remove PFAS compounds from their water sources. These regulations come in response to increasing evidence of the health risks associated with PFAS exposure, which can lead to a range of serious health issues, including cancer, liver damage, and developmental problems.

Technological Upgrades Required

The mandated technologies for PFAS removal include granular activated carbon (GAC), ion exchange, and membrane treatment systems. Each of these technologies requires substantial investment and infrastructure upgrades, which can be particularly burdensome for small water systems with limited budgets.

• Granular Activated Carbon (GAC): This method uses carbon to adsorb PFAS from water, effectively reducing contamination levels. However, the operational costs and the need for regular replacement of carbon media can add up.
• Ion Exchange: This technology operates by exchanging ions in water with ions on a resin, removing PFAS compounds. While effective, it also requires significant maintenance and replacement of resin materials.
• Membrane Treatment: Membrane systems, such as reverse osmosis, can be highly effective in removing PFAS but come with high energy costs and complicated upkeep.

Financial Implications for Small Water Systems

As of April 2026, many small utilities in North Carolina are grappling with the financial implications of these requirements. The costs of implementing PFAS removal technologies can range from hundreds of thousands to millions of dollars, a staggering expense for smaller systems that often operate on tight budgets. The analysis indicates that these costs compound existing infrastructure challenges, leading to concerns about the long-term viability of some systems.

For instance, a small water system serving a rural community may already struggle with outdated pipes and limited resources. The additional financial burden of upgrading to meet PFAS removal standards could stretch their budgets to the breaking point, potentially forcing them to increase water rates or seek emergency funding from state or federal sources.

The Broader Context of Water Quality

The situation in North Carolina reflects a national trend where water quality issues are prompting stricter regulations and increased scrutiny of drinking water sources. PFAS contamination has been identified in numerous states, and responses vary significantly based on local resources and political will.

In North Carolina, the Cape Fear River has been identified as a significant source of PFAS contamination, primarily due to industrial discharges. As communities along the river work to address these challenges, the need for comprehensive solutions becomes increasingly clear. Local government agencies and advocacy groups are calling for improved monitoring and better funding mechanisms to support water systems in their efforts to comply with new regulations.

Community Responses and Solutions

Community leaders and water system managers are actively seeking solutions to the PFAS problem. Some potential strategies include:

• Collaborative Funding: Local governments could pool resources to invest in shared treatment facilities, which could reduce costs for individual systems.
• State and Federal Assistance: Advocates are urging state lawmakers to provide financial assistance to small water systems, potentially through grants or low-interest loans specifically aimed at addressing PFAS contamination.
• Public Awareness Campaigns: Engaging the community in discussions about water quality and the importance of PFAS removal can help build support for funding measures.

Looking Ahead

The next five years will be critical for North Carolina’s small water systems as they work to comply with PFAS removal mandates. The decisions made now will shape the future of drinking water quality and public health in the state. As these communities navigate the complex landscape of regulatory compliance, financial sustainability, and public safety, the need for innovative solutions and robust support will be paramount.

In conclusion, while the challenge of PFAS contamination is daunting, it also presents an opportunity for communities to come together, invest in their infrastructure, and advocate for cleaner, safer drinking water for all residents. The path forward may be fraught with difficulties, but with concerted effort and collaboration, North Carolina can lead the way in addressing one of the most critical environmental issues of our time.
