Query EPA Envirofacts

meta.yaml is the executable contract. Use only released operations.

<!-- BEGIN GENERATED OPERATION STATUS -->

Current catalogue release status

meta.yaml is authoritative. Execute only operations listed as Released below; other sections in this playbook may document provider or unreleased adapter scope.

Released

• us/epa/envirofacts:search-tri-facilities — Query tri.tri_facility by exact identifier/state and case-insensitive name/city containment with bounded rows.
• us/epa/envirofacts:search-water-systems — Query sdwis.water_system by exact PWSID/state and case-insensitive name/city containment with bounded rows.

<!-- END GENERATED OPERATION STATUS -->

Choose the program table

• search-tri-facilities queries tri.tri_facility.
• search-water-systems queries sdwis.water_system.

catalogue query us/epa/envirofacts --operation search-tri-facilities \
  --input '{"state":"RI","name":"chemical","limit":10}'
catalogue query us/epa/envirofacts --operation search-water-systems \
  --input '{"state":"VT","name":"Springfield","limit":10}'

The adapter uses the current /dmapservice grammar documented by EPA. Text comparison is case-insensitive, exact identifiers use equals, name/city uses contains, and results are sorted and bounded.

Interpret narrowly

A TRI facility row identifies a facility in the TRI program; it does not say which chemicals were reported or how much was released. A water-system row identifies the system and activity metadata; it does not answer whether the water is safe or whether violations exist. Use the relevant release, monitoring, violation, or ECHO evidence for those claims.

Read the API reference for current grammar, tables, operators, and limits. Read the query guide for identity resolution and follow-up evidence.
