Cyclopure made getting our well water tested for PFAS chemicals easy with clear easy to follow instructions for collecting and mailing our water sample. We were impressed & appreciated the very detailed report & the information that clearly explained the findings for our water test.

You were fast, helpful, and now I have data I can work with. We started better filtration right away. I'm recommending you to my neighbors. Thank you.

You did what I contracted you to do on a timely manner and provided a complete report regarding the water sample I sent you. And my water sample did not have any PFAS detected by your testing procedure.
