How this page is built
Each utility's row is sourced directly from that utility's own published Lead Service Line Inventory (no federal aggregator exists). Systems are grouped by the city EPA records as the utility's base, which is usually but not always the same as the area it serves; see methodology. An automated verifier re-fetches every source on a monthly cron.
