PFAS Communications Guide

PFAS in Drinking Water Communications Guide
Access resources for developing messages for communities on public water systems about per- and polyfluoroalkyl substances.
Researchers at Extension and UW-Madison Department of Communication Arts teamed up to better understand public perception on PFAS and FPAS risk and developed communication recommendations for public health officials based on their findings. This guide walks you through risk perception for emerging contaminants like PFAS in their drinking water as well as where current communications fail to meet the demand for actionable solutions. This practical playbook will help you create messaging that is clear, culturally nuanced, and actionable for the communities you serve.
Key Messages for Public Health Communicators
Use the same language and keywords the public uses—especially “PFAS” and “forever chemicals.”
People overwhelmingly search using “PFAS” (6× more than “forever chemicals”), and rarely use technical names like PFOS or PFOA. Using these popular terms in headlines, social media, and web content improves search visibility and ensures messages appear in the same digital spaces where people are seeking answers.
Emphasize actionable guidance.
Nearly half (48.9%) of PFAS-related searches ask how to filter or remove PFAS from water. Far fewer ask about what PFAS are or where they come from. Communicators should prioritize practical self-efficacy information—how to test water, what filters work, and what bottled or tap water is safe—rather than focusing primarily on the chemistry or uncertainty of PFAS hazards.
Frame messages around exposure reduction and safety choices, not just risk awareness.
Searchers’ questions reveal that the public already perceives PFAS as something to avoid and wants to know how to act. Effective communication should reinforce this motivation by framing content around clear, feasible behavior changes—such as selecting affordable filtration systems or identifying PFAS-free water sources—especially for communities most affected by contamination.

Self-Efficacy
These emphasize the individual’s ability to perform the recommended action (e.g., using a pitcher filter).
Collective Efficacy
These emphasize the overall effectiveness of the recommended action (e.g., using a pitcher filter).
Susceptibility
These focus on how personally at risk individuals are to PFAS exposure.
Severity
These focus on how personally at risk individuals are to PFAS exposure.
Self-Efficacy for Latino Communities
These emphasize the individual’s ability to perform the recommended action (e.g., using a pitcher filter). These messages were developed in partnership with Wisconsin EcoLatinos.
Risk for Latino Communities
These focus on how personally at risk individuals are to PFAS exposure. These messages were developed in partnership with Wisconsin EcoLatinos.

Published in the Science Communication, this paper explores how risk based messages impact behavioral intention, advice, outcomes, and perceived importance. Findings indicate that efficacy cues and tailoring the messaging to the intended audiences readiness for behavioral change are important for effective communication.
