Evidence-backed facts

  1. Envirofacts provides a RESTful data service over documented EPA tables with JSON by default and several alternate export representations. informative
  2. The service aggregates data from multiple environmental programs, so table, column, join key, operator, range, sort, and format are part of the query contract. informative
  3. Requests must complete within the documented execution window; broad retrievals should be paged instead of assuming one unbounded response. informative
  4. Aggregated environmental records can differ in source method, refresh schedule, geography, and completeness and do not establish exposure, causation, or legal compliance. informative
