About PurityRadar
Know if your water is safe to drink. PurityRadar turns EPA and USGS data into a personalized 0–100 score per address or well, with trends, advisories, and filter recommendations. Every number traces back to a public record — Safe Drinking Water Act violations, PFAS and lead testing, enforcement history, and USGS groundwater models — so you get the evidence, not just a verdict. It spans ~49,000 community water systems and private wells nationwide, and it's free, independent, and sells nothing.
