PurityRadar is a free tool that shows you what's in your local drinking water. Enter any US address or ZIP code and get an instant, plain-English report on your water system — a 0–100 quality score, the contaminants detected (PFAS "forever chemicals," lead, arsenic, disinfection byproducts and more), and how each stacks up against EPA health limits. Every report is built entirely from public federal records — primarily the EPA's Safe Drinking Water Information System and UCMR5 monitoring, plus USGS data — covering the roughly 50,000 community water systems that serve US households.
Beyond the score, PurityRadar helps you act on it: match a water filter to the specific contaminants in your area, find state-certified testing labs, browse city and state water directories, and compare your community against others. It's independent and non-commercial — no scare tactics, no paid endorsements — built to turn dense public data into clear, practical answers about the water you drink every day.
