So far so good just waiting for my results
By Craig
This company had great communication and got their products to us quickly and efficiently, answered all questions, and worked with us to get us what we wanted. Great company overall, would definitely use again.

1) The sample source description you provide is, sometimes, less specific than what I submit. Should always be just what I write on the submittal form. 2) Pricey!

Response from Cyclopure· Mar 29, 2026
Hi! Your results were sent to your email address on 3/25/2026. Perhaps they ended up in your Spam folder. We require 10-14 BUSINESS days to complete analysis and publish reports. We received your kit back at the lab on 3/10/2026. We forwarded the results to you again from a different Cyclopure email address , but unfortunately the email was rejected again by the AOL server. We will send them out via US Postal Mail to your PO Box. Thanks for testing your water for PFAS with Cyclopure.
Outstanding customer service. When I forgot to include information with my kit I was able to reach out and the problem was taken care of immediately. Just got our results back! 10/10 process and service

Quick service and return of results

We live in an ag area with an old, not-deep well for house water. There are a lot of biosolids being spread nearby and we are worried about pfas. This test gave us some assurance that our water is safe.
