Free area screening

What’s in your water?

Enter your ZIP code to see the environmental factors documented in public EPA and state records for your area — and the laboratory test that’s the right place to start.

Screening only — based on public, area-level data. It is not a measurement of your home.

What this tells you

Which contaminants have shown up in public, area-level records near your ZIP — from EPA and state environmental databases, water-system reports, and documented sites. It’s a smart starting point for deciding what to test first.

What it does not tell you

It does not mean any contaminant is in your home’s water or air. Area data can’t see your street, your plumbing, or your well. Only a laboratory test of a sample from your property can tell you what’s actually there.
