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.
