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.

Easy to figure out what I wanted, went with extreme for the capacity. First one arrived damaged, customer service was responsive and another filter delivered within 3 days. Installed, waited a few weeks, ran test and no pfas detected.

My blood test came back positive for elevating PFOS. I wanted to test potential water sources without breaking the bank, and this service fit the bill. If I need additional water testing, I plan to come back. Used it twice so far to test drinking water at work and at home.
