Understand your home's water before you buy treatment.
Identify the likely water provider, understand reported local information and match your concern with the right next step — a test, an appropriately certified product or a local professional.
Three steps to an honest answer
No account, no pressure, about two minutes.
Identify your source
Enter your address or ZIP and we identify your likely public water system — or start the private-well path.
Describe what you notice
Tell us what you see, smell or already know, and what evidence you have — a symptom is a clue, not a test.
Compare next steps
See what is known, what isn't, and one clear next step: learn, test, compare products or talk to a local pro.
What's going on with your water?
Start from what you've noticed.
What we can — and cannot — tell you
We can
- Identify a likely public water system for your address
- Show information reported for that system, with sources
- Help organize symptoms, evidence and goals
- Match your situation to an honest next step
We cannot
- Determine exactly what is in your home's water
- Replace a sample tested by a qualified laboratory
- Diagnose a cause from a symptom alone
- Give your water a safety score — no one honestly can
City water or private well?
They're different questions, so we treat them differently.
I'm on a public utility
See your likely provider, the latest reported data and what it does — and doesn't — say about your tap.

Wells are the owner's responsibility. Organize your symptoms and test history into a responsible testing or treatment path.

Common questions
Is this a free water test?
No. We show reported information for your likely water system and help you decide whether a real laboratory test is worth it. Nothing here tests the water at your tap.
Will my info be sold to a bunch of dealers?
No. If a professional route fits, we show you one named provider and ask before anything is sent — to that company only.
Is my area's water safe?
Area data can't answer that for your tap. We show what your utility reports, what it means, and when testing makes sense — without a made-up safety score.
Do you sell water systems?
We're an independent guide. Some links pay us a commission and providers pay for qualified requests — disclosed where it happens, and never deciding what we recommend.
