See what’s in your water— and where every number comes from.
A personalized 0–100 safety report for any US address or private well, with historical trends, live local advisories, and filters matched to your contaminants. Every figure traces back to a public source.
Why PurityRadar
Most checkers hand you a number. We show you the whole picture.
Anyone can surface a single reading. PurityRadar adds the context that actually helps you decide — history, locality, wells, and a clear trail back to the source.
Historical trends
See how your water has changed over years — not just a single snapshot.
Private wells, too
On a well? We model your area’s risk from USGS data — most tools ignore wells entirely.
Live & local
Boil-water advisories and water news for your exact area, with last-updated dates on every figure.
Every number is sourced — and signed.
Each figure links back to the EPA, USGS or utility record behind it, with the date it was published and a named expert reviewer. No anonymous scores, no black box.
