I was worried that my well water may have been infused with PFAS, after reading a news article in the Portland Press about your testing I signed up for your low cost testing PFAS testing, a simple water sample was sent to Cyclopure and shortly thereafter my negative results came in. Thank You!

Great Experience
The test was very easy to complete. Everything you needed was in the kit, and it did not take very much time at all. The kit was delivered promptly, it was easy to box up and send in our sample, and the results were emailed to us quickly.

We paid extra for a water filtration unit that claimed it would remove all pfas. This test confirmed our unit is working properly.
