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.
