Real EPA enforcement data — not scare tactics. Search your city to see lead levels, violation history, and an honest water quality grade.
We pull directly from the EPA's Safe Drinking Water Information System — the same federal database regulators use. No estimates, no fear-mongering, no affiliate filter sales.
Find any of 30,524 cities across all 50 states with a single search.
Lead levels in ppb, MCL violation history, compliance status — straight from the EPA.
A–D grades based on actual MCL violations — not aspirational MCLG limits that make every city look dangerous.
We use only EPA SDWIS data — the federal gold standard for drinking water compliance. Unlike sites that use MCLG detections to manufacture fear and sell filters, we show you what actually matters: whether your utility has violated legally-enforceable Maximum Contaminant Levels.
