PERSIST study
PFAS Exposure Research: Studying Impact with Surveys and blood Testing
About PERSIST
PFAS, sometimes called forever chemicals, are man-made substances that persist in the environment and the human body. The PERSIST study is a first step in understanding PFAS exposure and its potential health impact in communities across the Geisinger service area.
This pilot study, funded through philanthropic support, will help researchers better understand the degree of PFAS contamination in local water sources and how it may be reflected in blood levels among nearby residents. Findings will guide future, larger-scale studies.
Why this study matters
Recent reporting has highlighted growing concern about PFAS contamination in local water supplies and what it could mean for your long-term health. These chemicals have been detected near some communities, raising questions and concerns about potential exposure.
By combining community surveys with blood testing, this research will help answer critical questions about real-world exposure in our region. The goal is to provide clearer insight, reduce uncertainty and support informed public health decisions moving forward.
What the study involves
Participation is simple. If you enroll, you’ll be asked to:
- Complete a brief questionnaire about your lifestyle and environmental exposures
- Provide a blood sample
Starting in Summer 2026, the study aims to enroll 200 participants of all ages.
Who can participate
You may be eligible to participate if you:
- Live (or have lived) in North Centre Township and your public or private water source has tested positive for PFAS
- Are willing to complete the survey and provide a blood sample
Why participate
By joining the study, you’ll help researchers better understand PFAS exposure in your community and contribute to efforts that may inform future public health decisions and environmental protections.
