EPA vs Open Government, ACT

EPA's Envirofacts platform exposes the agency's environmental compliance and monitoring databases — air quality, drinking water systems, the Toxics Release Inventory, hazardous waste, and Superfund sites — through a keyless REST API at `data.epa.gov/efservice`. Any of the underlying tables can be queried by building a URL from the table name, filter columns, and an output format, with results returned as JSON, XML, CSV, or Excel. EPA's Developer Central site separately documents smaller topic widgets built on the same data.

Data.act.gov.au is the Australian Capital Territory's open-data portal, run on Socrata; its catalog discovery API at `www.data.act.gov.au/api/catalog/v1` answers keyless GETs with full dataset JSON and a wildcard `Access-Control-Allow-Origin` header (the bare `data.act.gov.au` apex briefly redirects through plain HTTP before landing back on the `www` host over HTTPS, so link to `www` directly). Individual datasets are queryable through Socrata's SODA API in JSON or CSV, covering ACT government services, planning, and community data.
