This sandbox can be used to get data for only one kind of resource, that is, to fetch data for a string contained in the meaning of any of the words.
The remaining resources work a similar fashion. For details, see the reference documentation.

Enforcement and Compliance History Online (ECHO) is a tool developed and maintained by EPA's Office of Enforcement and Compliance Assurance for public use. ECHO provides integrated compliance and enforcement information for over 1 million regulated facilities nationwide.
ECHO Rest Services provide multiple service endpoints, each with specific capabilities, to search and retrieve data on facilities regulated as Clean Air Act (CAA) stationary sources, Clean Water Act (CWA) dischargers, Resource Conservation and Recovery Act (RCRA) hazardous waste generators/handlers, and Safe Drinking Water Act (SDWA) public water systems. Data of interest from other EPA sources, such as the Toxics Release Inventory, is also supplied for context.
\
The getfacilities, getmap, getqid, and getdownload end points are meant to be used together, while the enhanced getfacilityinfo end point is self contained.
The getfacilityinfo end point returns either an array of state, county or zip clusters with summary statistics per cluster or an array of facilities.
\
The recommended use scenario for getfacilities, getqid, getmap, and getdownoad is:
\
1) Use getfacilities to validate passed query parameters, obtain summary statistics and to obtain a queryid (QID). QIDs are time sensitive and will be valid for approximately 30 minutes.
2) Use get_qid, with the returned QID, to paginate through arrays of facility results.
3) Use get_map, with the returned QID, to zoom in/out and pan on the clustered and individual facility coordinates that meet the QID query criteria.
4) Use get_download, with the returned QID, to generate a Comma Separated Value (CSV) file of facility information that meets the QID query criteria.
\
\
Use the qcolumns parameter to customize your search results. Use the Metadata service endpoint for a list of available output objects, their Column Ids, and their definitions to help you build your customized output.

Enforcement and Compliance History Online (ECHO) is a tool developed and maintained by EPA's Office of Enforcement and Compliance Assurance for public use.
ECHO provides integrated compliance and enforcement information for over 1 million regulated facilities nationwide.
EFF Rest Services provides the data for ECHO's Effluent Charts, a set of dynamic charts and tables of permitted effluent limits, releases, and violations over time for Clean Water Act (CWA) wastewater discharge permits issued under the National Pollutant Discharge Elimination System (NPDES).
See Effluent Charts Help (https://echo.epa.gov/help/reports/effluent-charts-help) for additional information.
\
The are 3 service end points for Effluent Charts: getsummarychart, geteffluentchart, and downloadeffluentchart.
\
1) Use getsummarychart to retrieve a summary matrix of effluent parameters by effluent outfall and an overall violation status for a provided NPDES Permit and date range.
2) Use geteffluentchart to retrieve detailed Discharge Limit, DMR and NPDES Violation information for a provided NPDES Permit, date range, effluent parameter, or outfall.
3) Use downloadeffluentchart to generate a Comma Separated Value (CSV) file of the detailed data provided with get_effluent chart, for a provided NPDES Permit, date range, effluent parameter, or outfall.
