Your well test came back. Here's what it actually says.
Upload a report from any certified lab. Every number gets explained in plain English, with what to do next and a reminder when it's time to test again.
Try it on the sample report: tap any line to decode it.
Private well, untreated tap
Sample data for illustration. Limits are EPA standards for public water, the usual yardstick for private wells.
About 43 million Americans drink from a private well. No utility tests that water, and USGS sampling found about 1 in 5 wells had a contaminant at a level of potential health concern.

Built for the moment the envelope from the lab arrives and none of it makes sense.
Upload your report
A PDF from the lab, or a phone photo of the page. Any state certified lab works.
Read it in plain English
Each result is checked against EPA limits and explained: what it is, whether it matters, and what to do about it.
Never miss a test
Yearly reminders for bacteria and nitrate, and a nudge to retest after floods, well repairs or a new baby in the house.

What we will and won't do
Water advice is full of people selling filters. We aren't one of them.
- Explain, not sellNo filter or treatment sales pitch. When treatment helps, we tell you what type to look for.
- Never call your water “safe”We compare results with official limits. Real problems go straight to your local health department.
- Your results stay yoursNever sold or shared. Delete your data whenever you like.
- Any lab, no lock inUse the lab you already trust. We don't run a lab or sell test kits.
“I’ve spent twelve years working with water data, and a PhD on water information systems. The science on well water is clear. The paperwork people get back from the lab isn't. WellDecoded is the plain-English translation I'd want for my own family.”Nour Attaallah, PhD, founder
Questions
Does WellDecoded test my water?
No. You test with a state certified lab, and we explain the report you get back. If you haven't tested yet, we'll point you to certified labs in your state.
Which lab reports will it read?
Reports from any certified lab, as a PDF or a clear photo. If something can't be read, you can type the number in instead.
Is it free?
Early access is free. Founding members will also get a lower price, locked in, on any paid features we add later, like testing history and household plans.
Is this medical advice?
No. It explains your results against official drinking water limits so you can make good decisions and ask better questions. For health concerns, talk to your local health department or doctor.
Where does it work?
We're starting in the United States, using EPA limits and state guidance. Canada is next.
