Thanks for your interest in the West Plains PFAS Filter Study! Here’s the process to participate.

Phase 1 - 60 households - OPEN

Update November 11, 2026: We are 50% of the way toward our goal of 60 households. Testing is still available for 30 more households!

Phase 1 will test the effectiveness of 60 filters already installed in households on the West Plains. To enroll:

Fill out the eligibility screening form. This form will collect some initial information about your well and any existing water treatment systems in your home to determine if you are eligible. Our team will review the eligibility form and reach out to you for the formal enrollment process if your home fits the study criteria.

Complete the enrollment survey. If you are eligible to enroll, we will send you a link to a online survey. This survey will collect:
- Your formal agreement to participate in the study (consent).
- Information about water use in your household
- Information about your perceptions of PFAS contamination and the effectiveness of different responses.
Collect water samples. Once we have your formal enrollment survey, we will send you a kit via FedEx with instructions to collect water samples from your filtered and unfiltered water. The kit will include a pre-paid return shipping label for you to mail the samples back to the University of Colorado Boulder.

Phase 2 will install new systems in 12 households with high PFAS levels and test them over time.

We have completed enrollment of all households for Phase 2 testing.
