About
PurityRadar turns public drinking-water records into a report you can actually read. Enter any US address, city, ZIP, or utility and get a 0–100 safety score for your water system, broken down by contaminant — PFAS, lead, nitrate, arsenic, trihalomethanes, and 90 more. Unlike most water-quality tools, PurityRadar shows historical trends rather than a single snapshot, so you can see how your water has changed over years. It covers private wells too, modeling area risk from USGS data — something most tools ignore entirely. Live boil-water advisories and local water news are surfaced for your exact area, with a last-updated date on every figure. Every number traces back to a public source: EPA SDWIS violations, UCMR5 PFAS occurrence, Lead & Copper Rule actions, enforcement history, and ambient monitoring across roughly 49,000 US community water systems. When your report flags something, PurityRadar matches filters certified to reduce those specific contaminants and connects you with local providers. Independent, free to search, and built to be checkable — not a filter company's lead magnet.
