Introduction: The Urgent Challenge of PFAS in Small Communities
As concerns over PFAS (per- and polyfluoroalkyl substances) grow, small water treatment plants (WTPs) across the country face mounting pressure to act. Known as “forever chemicals,” PFAS compounds resist degradation, accumulate in the environment, and pose serious health risks — even at trace levels.
While many small municipalities recognize the urgency, budget constraints, technical complexity, and evolving regulations often delay action. Fortunately, there are actionable, cost-effective solutions available that can help small WTPs begin addressing PFAS contamination today — without waiting for federal mandates.
This article summarizes key insights from Water Online’s recent article on how smaller communities can tackle PFAS more easily and effectively.
Flexible Systems for a Changing Regulatory Landscape
Future-Proofing Filtration Infrastructure
One of the biggest risks for small utilities is investing in a system that may not meet future regulatory limits. This makes modular, upgradable filtration systems essential. Unlike bulky reverse osmosis (RO) or large granular activated carbon (GAC) beds, carbon cartridge systems offer a scalable solution with a small footprint. These can be easily modified or expanded to meet tighter future standards.

Going Beyond Initial Costs: Total Cost of Ownership
Training, Maintenance, and Disposal Matter
Capital expense is only part of the equation. Ongoing operational costs—including media replacement, waste disposal, and staff training—can make or break a PFAS program.
Key cost considerations include:
- Disposal of spent PFAS media (not landfill-safe)
- Operator certification and training
- Consumables like IX resin, GAC, or membranes
Cartridge systems again stand out here, offering easier replacement processes and fewer specialized requirements.
Simplified Operation for Better Workforce Fit
Meeting Workforce Challenges with Operator-Friendly Design
Small communities often struggle to recruit and retain highly certified operators. Systems that are intuitive, low-maintenance, and monitorable via SCADA or smartphone offer a practical advantage.
For example, carbon cartridge filters notify operators when it’s time to change the cartridge—no complex lab testing needed. This reduces training needs and operational risk.
Easy Installation Equals Faster Implementation
Fast Deployment = Faster Protection
Many PFAS solutions are complex to install, involving welding, multiple tanks, or custom engineering. Small communities benefit from systems that use standard plumbing tools and require minimal infrastructure changes.
This makes cartridge-based systems attractive for:
- Remote communities
- Pop-up emergency deployments
- Rapid upgrades of outdated systems
Conclusion: Take Action Today, Not Tomorrow
Waiting for federal PFAS regulations may seem prudent—but the health consequences of delayed action are significant. Small water systems can—and should—start now with scalable, operator-friendly, cost-effective technologies.
As highlighted in the Water Online article, the right solution doesn’t have to be complex or costly. By choosing wisely today, communities can protect their residents and prepare for whatever regulations come tomorrow.
