“Forever chemicals” are becoming a long-term planning issue for drinking water systems
PFAS is seeping from technical discussions into everyday conversations in Georgia. Recent detections in drinking water have brought these chemicals further into public view, and regulators have continued to expand PFAS sampling across the state. For utilities, that changes the stakes. PFAS isn’t just a compliance issue. It is also a long-term infrastructure challenge tied to treatment strategy, capital planning, and delivery models.
PFAS also lands differently than other drinking water concerns. It brings together public anxiety, scientific complexity, low regulatory thresholds, and expensive treatment conversations. It is not enough to detect a contaminant; utilities must also explain it clearly, plan for it early, and build a response they can sustain.
Why PFAS Draws Scrutiny
PFAS, often called forever chemicals, are a large family of synthetic chemicals used in industrial and consumer applications. They break down very slowly, which means they can persist in water, soil, and the human body. That persistence drives much of the concern. Once PFAS enters a water source, it rarely leaves quickly.
Health concerns have pushed the issue. PFAS exposure has been associated with cholesterol impacts, lower birth weight, reduced antibody response to vaccines, kidney and testicular cancer, pregnancy complications, and certain liver enzyme changes. Because of those risks, communities want answers, and regulators want action.
PFAS also challenge utilities in ways that differ from those of many other contaminants. The question is not only whether a system can measure PFAS at very low concentrations, but also whether it can interpret those readings and deliver treatment without letting costs spiral.
Rules Are Moving Fast
That challenge has become harder because the compliance picture keeps shifting. EPA’s drinking water rule sets enforceable limits for six PFAS and establishes a framework that accounts for mixture effects, recognizing that combined health impacts may matter even when individual compounds occur at lower levels.
Georgia has already started working through what that means. Stakeholders have been discussing rule updates that address monitoring, reporting, and compliance mechanics, as well as possible federal timing changes. Utilities cannot afford to wait until every implementation detail is finalized.
Federal signals have only reinforced that uncertainty. EPA said it would keep the maximum contaminant levels for PFOA and PFOS while also proposing a longer compliance runway, an exemption framework, and reconsideration for other PFAS standards. The broader direction remains clear: utilities should expect continued scrutiny and h3er expectations for treatment.
Monitoring expectations have expanded as well. The fifth Unregulated Contaminant Monitoring Rule (UCMR 5) required sampling for 29 PFAS between 2023 and 2025, and the EPA has identified the best available technologies to meet PFAS drinking water limits. That means monitoring and treatment now sit in the same conversation.
Where Costs Start to Climb
That next step is where PFAS turns from an environmental issue into a budgetary one. Many systems cannot treat PFAS contamination with a small process adjustment. They need advanced treatment, new equipment, greater operational oversight, and a long-term plan to maintain steady performance.
EPA’s technology and cost analysis highlights treatment options including granular activated carbon, ion exchange, reverse osmosis, and nanofiltration, along with recurring costs for media replacement, membrane replacement, energy, sampling, and analysis.
Municipalities feel that pressure. Capital costs rise first, but operating costs are close behind. Utilities must maintain performance, explain new spending to elected officials, and prepare ratepayers. Nationally, the burden has been framed at roughly $1.5 billion per year, with smaller communities facing some of the sharpest affordability pressures.
In Augusta, utility leadership said compliance with the new PFOS limit could require treatment investments large enough to drive a rate increase on their own. That is exactly why PFAS belongs in long-term planning now.
Advanced treatment requirements and evolving regulations are putting new pressure on water systems across Georgia. Understanding your options early can help manage costs, reduce risk, and avoid rushed infrastructure decisions.

Planning Before the Squeeze
Communities do not need every answer immediately, but they must start asking harder questions. Which source waters face the greatest exposure? Which treatment train fits the system’s scale, staffing profile, and budget? What can a utility phase in over time, and what might require a more immediate capital response? Which funding paths can support pilot work, design, testing, and construction?
Recent state funding in Georgia has gone to communities pursuing pilot studies, remediation technologies, new wells, and treatment upgrades tied to PFAS and other emerging contaminants. The Drinking Water State Revolving Fund also provides communities with an additional source of financing for compliance-related drinking water infrastructure and water quality improvements.
A Better Position to Act
Communities that assess their options early usually keep more control over cost, sequencing, and delivery. That might mean pairing technical evaluation with a thorough look at procurement and financing options, including leasing treatment plants, phased implementation, and full-service delivery models such as Water-as-a-Service®. Those models help communities coordinate treatment delivery, long-term operations, and funding strategy under a more manageable structure.
At Seven Seas Water Group, we help utilities look at the full picture. PFAS planning requires more than selecting a practical path to compliance that communities can afford to deliver and sustain. The earlier that evaluation begins, the more workable options remain on the table. To talk through treatment pathways, delivery structures, and funding strategy, schedule a consultation with us.
