  Find covered US cities by name, optionally within a state. Returns counts + the page URL for each.

• get_city_water

  The core tool: what the EPA has on record for a city's tap water — the active community water systems serving it, populations, sources, and violations (contaminant, health-based or not, dates, status, level vs limit when recorded). Plain-English, sourced, never a safety verdict.

• list_state_cities

  List all covered cities in a state (with violation counts).

• explain_contaminant

  Plain-English explanation of an EPA contaminant by name or code: the EPA name, whether the EPA classifies it as health-based, and how often it appears in our records. Not medical advice.
