Home Hazard MapDrinking water records, lead, PFAS and radon for every U.S. ZIP code — straight from EPA data, in plain English.
What this is — and isn’t. These are records your water utility and state reported to the EPA, and the EPA’s radon map for your county. They describe the system and the area, not the water from your own tap or the air in your home. For that, read your utility’s annual Consumer Confidence Report and test: lead and radon tests are inexpensive.
