The GenX Exposure Study is a research project. We generate data to help answer community questions about PFAS. Because we are doing research, we do not know what we will find. Some of these chemicals are newly identified, so the methods to test for them are not routine and take time to get accurate results.
We try to share results with study participants and communities in a timely fashion. We take our time to ensure that the results we share are the most accurate we have at the time.
Explore our collection of materials including Newsletters, Report Back Letters, Community Meeting slides and recordings, and Scientific Papers.
Please remember that our data are still under revision and are not intended for publication or citation.
Every few months, we send newsletters to our study participants and share them here. The newsletters include study updates and information about different PFAS topics. These are available in both English and Spanish.

Report Back Letters
We share initial results with our participants first. These report back letters are examples of what we send to participants when their results are available. Each letter includes information about the study as well as a personalized analysis of the different chemicals that were tested.
Between November and December 2017, we sampled tap water in 198 homes in New Hanover County and reported those results in April 2018 (English and Spanish). In May 2018, we sampled 27 more homes and shared those results in April 2019.
In February 2019, we sampled tap and well water from 85 homes in Cumberland and Bladen County. We reported our results to participants in May 2020.
We sent PFAS results to 90 participants who wore silicone wristbands as part of the study in the Fayetteville area.
After sharing individual letters, we try to hold meetings in the communities we are working to discuss our findings more broadly and answer questions.
Virtual Fayetteville Community Meeting (Slides)
June 2020 | Fayetteville, NC
- Drs. Hoppin and Kotlarz shared the PFAS results from the private wells sampled in February 2019.
October 2020 | University of North Carolina Wilmington
- Dr. Hoppin discussed the GenX Exposure Study and upcoming recruitment with members of the UNC-Wilmington Latino Alliance.
New Hanover Drinking Water Community Meeting (Slides)
April 2018 | Wilmington, NC
- Dr. Kotlarz provided PFAS tap water results to Wilmington residents.
November 2018 | Wilmington, NC
