Tools

10 tools listed at last check
  • search Search TapWaterMap for US cities by name. Returns matching cities with an id you can pass to `fetch`. (ChatGPT/Deep-Research compatible.)
  • fetch Fetch the full plain-English EPA tap-water record for a city id (e.g. 'vt/burlington') returned by `search`. (ChatGPT/Deep-Research compatible.)
  • search_cities 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.
  • get_water_system EPA record for a single water system by its PWSID (e.g. 'VT0005053'): name, population served, source, and violations.
  • list_state_cities List all covered cities in a state (with violation counts).
  • find_cities Filter/rank cities across the dataset — e.g. cities in TX with open health-based violations, or cities with a specific contaminant. Returns ranked matches.
  • compare_cities Compare the EPA records of several cities side by side. Pass cities as 'City, ST' strings.
  • 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.
  • coverage_stats What TapWaterMap covers: states, cities, total EPA violation records, and the data quarter/date.
