Year 12 Pilot: Measuring “forever chemicals” in North Georgia communities

PI: Melanie Pearson, School of Public Health, Environmental Health

Study year: 2024

Drinking water in Rome and Calhoun, Georgia, has elevated levels of per- and polyfluoroalkyl substances (PFAS) from local industry. These substances are known as “forever chemicals” because they are nearly indestructible and build up in plants, animals, and humans. PFAS health effects include reduced immune function, higher cholesterol, lower birth weight, and kidney and testicular cancer. The city of Rome will install a new water treatment plant in the fall of 2025 to reduce PFAS from the drinking water. Residents are concerned about their PFAS exposure and the effectiveness of water treatment. This study aims to evaluate the levels of 18 PFAS chemicals in the blood of 200 residents, comparing them with national averages and between the two cities. It will also provide useful baseline data to assess the treatment plant’s effectiveness. Results will be shared with participants and the community to inform decision-making. Importantly, this study was developed with the input of residents and organizations and will continue to be guided by local partners throughout the project.

How this study advances exposome science: This study advances exposome science by examining PFAS exposure levels in a community disproportionately affected by industrial contamination while also providing data to assess whether new water treatment technologies can reduce PFAS exposure. We are collaborating with diverse partners and organizations to ensure multiple perspectives are considered in study design, implementation, communications, and next steps. This inclusive approach ensures that the study is representative of the community and its concerns, making the research more relevant and impactful.
