PFAS Myths vs. Facts: What Organizations Need to Know to Manage Risk

PFAS Myths vs. Facts: What You Need to Know

Per- and polyfluoroalkyl substances (PFAS) are receiving increased attention from regulators, the media, and the public. Often labeled “forever chemicals,” PFAS are driving new regulations, increased enforcement, and growing litigation. For organizations working to keep pace, misinformation can make an already complex issue more difficult to manage.

Understanding the difference between myth and fact is essential for informed decision-making, regulatory compliance, and effective planning.

Myth 1: PFAS Only Affect Drinking Water

Fact: PFAS can impact far more than just drinking water.

While recent EPA regulations have focused on drinking water, PFAS contamination can occur in soil, groundwater, surface water, sediment, wastewater residuals, landfill leachate, and air emissions. These chemicals were widely used in firefighting foams, manufacturing, textiles, and food packaging, contributing to their widespread presence in the environment.

When evaluating PFAS risk, focusing only on drinking water is inefficient. A multi-media assessment is often necessary to fully understand potential risks, liabilities, and compliance obligations. Without this approach, organizations may underestimate risk exposure and face unexpected compliance or remediation costs.

Myth 2: All PFAS Are the Same

Fact: PFAS represents a diverse group of chemicals with varying behaviors.

There are thousands of PFAS compounds with differing chemical structures, chain lengths, and environmental behaviors. Some migrate rapidly through groundwater, while others bind to soil or organic material. Regulatory standards currently address only a subset of PFAS, and analytical methods and risk frameworks continue to evolve.

Effective PFAS management requires site-specific evaluation of geology, groundwater flow, and chemistry. Treating PFAS as a uniform group can lead to incomplete site characterization and ineffective remediation strategies.

Myth 3: PFAS Remediation Is Simple & Straightforward

Fact: PFAS remediation is complex and requires strategic planning.

PFAS are highly stable and resistant to traditional treatment methods. Most current approaches focus on removal or containment rather than destruction. Common technologies include granular activated carbon (GAC), ion exchange resins, and membrane filtration.

Emerging destruction technologies show promise but are not yet widely implemented. Successful remediation requires evaluating feasibility, lifecycle costs, regulatory expectations, and management of residual waste streams. There is no one-size-fits-all solution. Inadequate planning can lead to higher life cycle costs and regulatory delays.

Myth 4: PFAS Is Only an Industrial Problem

Fact: PFAS exposure affects a wide range of sectors.

While industrial use has been a major source, PFAS concerns now extend beyond manufacturing. Municipal water systems, wastewater utilities, landfills, airports, military installations, and commercial properties are all impacted.

Organizations that have not historically managed PFAS are increasingly required to consider it within compliance strategies, permitting processes, and capital planning.

Myth 5: You Can Solve PFAS by Simply Switching Products

Fact: Reducing PFAS risk requires a broader, system-based approach.

Although there is increasing momentum to eliminate PFAS from products, substitution alone is not always sufficient. Some alternatives may introduce new environmental or regulatory risks. Relying solely on product substitutions can leave gaps in risk management and lead to incomplete compliance strategies.

A more effective strategy includes evaluating supply chains, reviewing procurement practices, understanding waste streams, and making risk-based decisions. Proactive planning is more effective than reactive compliance.

The Regulatory Landscape Is Still Evolving

PFAS regulations continue to expand at both federal and state levels. EPA actions under the Safe Drinking Water Act, Toxic Substances Control Act (TSCA), Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), and National Pollution Discharge Elimination System (NPDES) are reshaping compliance requirements. States are also introducing reporting requirements, product restrictions, and environmental standards.

The overall trend is clear: regulatory requirements are increasing. Staying informed and maintaining thorough documentation is critical for managing compliance risk.

A Practical Approach to Managing PFAS Risk

Addressing PFAS requires more than testing or treatment; it requires a structured, comprehensive strategy.

A structured approach enables organizations to prioritize actions, manage costs, and remain aligned with regulatory expectations.
