Fostering efficacy and understanding in communicating the threat of PFAS and actions for PFAS risk reduction

Principal Investigator: Lyn van Swol
Affiliation: University of Wisconsin-Madison
Initiation Date: 2023

This project was funded through the “Social and Economic Impacts of PFAS in the Great Lakes and Lake Champlain Regions” opportunity. 

The main objective of our proposal is how to communicate risk to focus on factors that could increase compliance with PFAS recommendations (e.g., using water filtration systems) and avoid unintended consequences, such as dismissing a complex message due to lack of understanding or generating fear and threat perception without a means to alleviate the threat. We have three studies where we focus specifically on: 1.) What types of information people look for online about PFAS; 2.) what type of messaging is most effective for communicating about the health risk of PFAS in an experiment with a focus on the variables of efficacy to enact recommendations, level of fear and threat conveyed by the message, and complexity of the message, and, 3.) What PFAS-related messages are most engaging in a real-world paid message test conducted on social media to residents who rely on municipal water supplies, including tests targeting both English and Spanish-speakers.

Wisconsin Sea Grant will support outreach efforts for this project.


From Awareness to Action: Assessing PFAS exposure in communities and evaluating the effectiveness of its mitigation strategies

Principal Investigator: Ruohao Zhang
Affiliation: Pennsylvania State University
Initiation Date: 2023

This project was funded through the “Social and Economic Impacts of PFAS in the Great Lakes and Lake Champlain Regions” opportunity. 

The objectives of this study are: i) to advance the understanding of community risks of PFAS pollution exposure in MI, NY, and PA; and ii) to examine the effectiveness of the local regulations in the three states on motivating public awareness and avoidance behaviors.

New York Sea Grant is supporting outreach efforts for this proposal.


From Murky Runoff to Potable Water- Runoff Purifying Parking Lots

Principal Investigator: Sundeep Inti
Affiliation: Purdue University Northwest
Initiation Date: 2019

One of the significant issues with urbanization and a rapidly changing climate is an increase in storm-runoff and the speed of stormwater reaching the existing drainage system. The drainage system is overburdened by the amount of flows during rainfall causing flash floods. Also, the untreated runoff is released to local water-bodies. The pollutants in urban runoff can cause eutrophication that severely affects the aquatic life and creates an imbalance in the eco-system. The rationale for this research is to confront this global issue through a local solution.

The motivations for this study are 1) To develop a sustainable urban drainage system through purifying parking lots and roofs. 2) To develop a design procedure as well as materials for constructing purifying parking lots or roofs. 3) To collaborate with construction firms and stakeholders in transforming the research into practice. 4) To promote the economic, social, and environment rewards due to the sustainable drainage system to all beneficiary’s like local community, retail and commercial firms in the southern Lake Michigan area.
