The Challenge of PFAS Risk Communication
Communicating PFAS risks to consumers requires balancing scientific accuracy, health protection imperatives, and avoiding both false reassurance and unnecessary panic. Utilities, public health agencies, and healthcare providers face a communication challenge: PFAS health risks are real and require action, but proportionate communication that maintains public trust and guides effective protective behavior is essential.
What “Below the MCL” Means—and Doesn’t Mean
When utilities report PFAS levels below MCLs, clear communication should explain what this means: the water meets federal safety standards for the six regulated PFAS compounds. It should not imply: the water is PFAS-free, all health risks are eliminated, or unregulated PFAS are absent. Consumers deserve to understand that MCL compliance represents a regulatory floor, not a guarantee of zero PFAS exposure.
Vulnerable Population Messaging
Risk communication should specifically address vulnerable populations—pregnant women, infants, immunocompromised individuals—who may face different risk thresholds than healthy adults. Targeted guidance for these groups, including recommendations for point-of-use filtration during pregnancy or when formula-feeding infants in areas with measurable PFAS, provides actionable protective advice without implying catastrophic risk for average adults.
Treatment System Transparency
Utilities implementing PFAS treatment should communicate specifically which compounds their system removes, at what removal efficiency, and how consumers can verify ongoing performance through water quality reporting. Transparency about treatment capabilities and limitations builds credibility and helps consumers make informed decisions about supplemental protection such as point-of-use filtration
