Christine M.
I do not think it would be possible for the results to be non- detectable for the city of Bryan ,Ohio. The Ohio EPA did a random test of 106 typical cities in the state and the numbers ran from 5ppt to over 100 ppt.

Hi Christine - Our Water Test Kit for PFAS, funded by NIEHS, has been validated by numerous labs across the country, including side-by-side testing with Massachusetts DEP and Michigan EGLE. These reports van be found on our website under "Resources." The kits are used by the US Government. If you would like to re-test with us, we are happy to arrange for another kit to be shipped out.

I never received my test results

HI John, your results were sent to you on July 21 coming from the email address [email protected]. Perhaps they ended up in spam. We received your sample on 7/8, so your turn around time was 9 business days. I've forwarded the report again. If you have a minute please confirm receipt. Thank you!

I purchased a water test sometime ago and recently sent in the test in the box with the label as instructed and the package was returned unable to deliver-return to sender. I have reached out to Cyclopure twice and I am still waiting for a response back.

Hello John - We moved to larger lab space in December 2024. We announced the move for several months via email and on the website. My guess is you used the old return label that came with your purchase almost two years ago. Plesae write to us at [email protected] and we will be happy to email you an updated prepaid return label. We answer the phone at 312-639-5009 if you have any further questions. Thank you!

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.

Our team re-sent you the results you refer to in your review, after speaking with you on the phone. We hope you are satisfied with our service and will consider changing this review. Thank you.
