Well thought out and understandable sampling and mail-in process.

I responded to the initial offer and received a reply and then a kit with good instructions for testing my water. It was returned to the lab and I very quickly received the results, which are good! Thanks for the opportunities!

Thank you for the complementary water test results. I was surprised to learn that my PFAS concentration was above the standard level. Also thank you for sending the complementary water dispenser to help eliminate the PFAS contaminant.

The test was easy to complete and send back. The results were emailed back in a timely fashion. Although the data was a little overwhelming, the results specific to our well was detailed and eaay to read.
