Gore’s Use of Fluoropolymers
Most Gore products utilize a material called PTFE, an inert fluoropolymer with unique performance and durability benefits. Historically, the PTFE Gore purchased as raw material included trace residuals of PFOA, which was previously used by our suppliers as a processing aid.
For decades, Gore has proactively engaged with our raw material suppliers to eliminate PFOA from our supply chain. We currently only purchase PTFE from suppliers that certify they do not use PFOA in their manufacturing processes.
Gore follows the developing science and regulations and has proactively implemented industry leading environmental controls in our manufacturing plants to minimize the potential for adverse environmental impacts.
You can read more about Gore’s use of PTFE and our commitment to environmental stewardship here.

Water Sampling: Common Questions & Answers
Is Gore sampling the water from residents in the area?
As part of our data driven approach to assess ground water conditions at and around our facilities, Gore has contacted specific residents in the immediate area near those Gore sites that are included in the sampling plan approved by the MDE. The data collected at each phase of our plan guides our efforts as we’ve expanded the sampling in the community. Each data set informs our next actions.
All parcels within the sampling areas have received communication from Gore.
Maps of the sampling areas for each location can be found on the respective facilities page for each site.
How can I find out if my house is in the water sampling area?
Residents in the water sampling area were contacted directly by Gore. Maps of the sampling areas for each location can be found on the respective facilities page for each site. If you received communication from Gore, please contact our third party contractor, Arcadis. Contact information was provided in the notification letter.
What are the results of Gore’s residential well sampling?
Gore posted a graph of the initial testing results of our water sampling in November 2024 on the home page of this site. We are updating that figure on a monthly basis to include the most recent data.
I have questions about the POET system that was installed in my home. Who do I contact?
We recommend you contact the Arcadis hotline for assistance.
The US Environmental Protection Agency has a variety of resources available on their website.
