Envirofacts provides tools to retrieve environmental information, including preformatted query forms and mapping applications.

The query forms allow you to type in search criteria (e.g., county and state) to retrieve facility and chemical information. Once you submit the query, a report containing environmental information is returned that matches the criteria you submitted. The content varies, according to which form you use. If you would like to design your own query, refer to the Technical User page.

The mapping applications generate maps that display environmental information for the entire United States. You can either go to the mapping applications directly, or "Map the Results" of your query using EnviroMapper.

Envirofacts Multisystem

The Envirofacts Multisystem Query integrates information from a variety of databases and includes latitude and longitude information. Each of these databases contains information about facilities that are required to report activity to a state or federal system. Using this form, you can retrieve information about hazardous waste (including the Biennial Report), toxic and air releases, Superfund sites, and water discharge permits. This query is fully integrated with EnviroMapper.Go to TopTop


The federal government locates, investigates, and cleans up the worst hazardous waste sites throughout the United States. These sites are designated "Superfund sites." Common Superfund sites include abandoned warehouses, landfills, and industrial facilities that dumped hazardous waste into the environment before it was regulated. Use the Superfund Query form to retrieve information about designated Superfund sites.Go to TopTop


Permit Compliance System (PCS)
The Clean Water Act requires wastewater dischargers to have a permit that establishes pollution limits and specifies monitoring and reporting requirements. The National Pollutant Discharge Elimination System (NPDES) permits regulate household and industrial wastes that are collected in sewers and treated at municipal wastewater treatment plants. Permits also regulate industrial point sources and concentrated animal feeding operations that discharge into other wastewater collection systems or that discharge directly into receiving waters. The Water Discharge Permits query form allows you to retrieve permit information. The customized query engine allows you select any data element in PCS to build a tabular report or a Comma Separated Value (CSV) file for downloading. Go to TopTop

Safe Drinking Water Information
EPA collects data about how well water utilities comply with drinking water regulations and whether any enforcement actions were taken against utilities. This information is stored in the Safe Drinking and Water Information System database (SDWIS). Use the Safe Drinking Water Query form to view a utility's violations and enforcement history for the last ten years.Go to TopTop

National Drinking Water Contaminant Occurrence Information
In 1996, Congress mandated that a repository of drinking water occurrence information be created; this repository is the National Drinking Water Contaminant Occurrence Database (NCOD). The database holds information from a number of sources, including public water systems and source (ambient) water. NCOD contains regulated and unregulated contaminant data for public water systems. The NCOD Query Form allows you to access information on contaminant occurrence in an individual system or by geographical area.Go to TopTop

Drinking Water Microbial and Disinfection Byproduct Information
The Information Collection Rule (ICR) required water systems serving 100,000 people or more to collect samples and report on microbial (source water) and disinfection byproduct (treated water) levels for 18 months (July 1997-December 1998). Twelve months worth of these data is now stored in Envirofacts. Use the ICR Query Form to view reports at the water system, state, and national levels. Be sure to review the cautions on data use before interpreting the data.Go to TopTop


Biennial Reporting System
Detailed hazardous waste information is collected on the generation of hazardous waste from large quantity generators and data on waste management practices from treatment, storage, and disposal facilities. This information is compiled into a Biennial Report and is useful for trend analysis.Go to TopTop

The Brownfields Management System (BMS) stores information reported by EPA Brownfields grant recipients on brownfields properties assessed or cleaned up with grant funding. In addition, fact sheets about Brownfields Where You Live are available. More information on the Brownfields production.

Superfund is a program administered by the EPA to locate, investigate, and clean up uncontrolled hazardous waste sites throughout the United States. More information on CERCLIS

Resource Conservation and Recovery Information System
Hazardous waste generators, transporters, treaters, storers and disposers of hazardous waste are required to provide information on their activities to state environmental agencies. These agencies then provide the information to regional and national US Environmental Protection Agency (EPA) offices through the Resource Conservation and Recovery Act Information (RCRAInfo) System. Information on cleaning up after accidents or other activities that result in a release of hazardous materials to the water, air or land must also be reported through RCRAInfo. This information is available to you using the Hazardous Waste Data query form.


The Grants Information and Control System is used by Headquarters, regions, and states to track, award, administer, and monitor grants. Envirofacts provides the public with timely award information for most of EPA's Federal Grant Programs, specifically Construction, Non-Construction, and State Revolving Funds grant programs. The Grants Information query form allows you to read about projects that have received grants.Go to TopTop

Locational Information

Locational information for EPA-regulated facilities in Envirofacts is cultivated from many sources, including EPA federal program systems (through monthly snapshots), and EPA regional offices and the states (through Supplementary Return Files). This information is collected and refined under the auspices of the Locational Data Improvement Project (LDIP), which was enacted by the Agency to comply with the federal Locational Data Policies (LDP).

The locational information in Envirofacts is stored in the Locational Reference Tables (LRT). The LRT act as a storehouse for the actual locational data, as well as the business rules that are applied to them in order to provide the most accurate information available for depicting the locations of federally regulated entities. The EZ query allows you to select key data elements from EPA's Facility Information database and Locational Reference database to build a tabular report or a Comma Separated Value (CSV) file for downloading. Go to TopTop

Facility Information

The Facility Registry System in Envirofacts was derived from several sources, including all of the program systems in Envirofacts. Use the Facility Registry System query form or the Facility Registry System EZ Query to view facility data.Go to TopTop


The RadNet, formerly Environmental Radiation Ambient Monitoring System (ERAMS), is a national network of more than 200 monitoring stations distributed across all 50 states and the American Territories. Each station regularly samples the nation's air, precipitation, drinking water, or pasteurized milk for a variety of radionuclides (e.g., iodine-131) and radiation types (e.g., gross beta (b)). Use the RadNet System query form or the RadNet System Customized Query to view radiation data. The Radiation Information Database (RADINFO) Query allows you to retrieve selected data from RADINFO database in Envirofacts regarding facilities or sites that EPA regulates for radiation and radioactivity. Go to TopTop


Envirofacts contains information about stationary sources of air pollution (facilities) in the Aerometric Information Retrieval System (AIRS)/AIRS Facility Subsystem (AFS). Examples of facilities (sources) include electric power plants, steel mills, factories, and universities. Use the Air Releases query form to retrieve both emissions and compliance information for these facilities.

The UV Index query form predicts the next day's ultraviolet radiation levels for a particular city or ZIP code based on a 0-10+ scale. Go to TopTop


The Envirofacts Master Chemical Integrator query form allows you to obtain the acronyms, chemical identification numbers, and chemical names reported in Envirofacts. Chemical information is also available using the Air Release, Toxic Release, and Water Discharge Permits query forms.Go to TopTop

Toxic Releases

The main purpose of the Toxics Release Inventory is to provide the public with information about potentially hazardous substances in their community. Currently 600 chemicals have been determined to be toxic, and certain industries must report to EPA if they use or handle these chemicals. This reported information is contained in Envirofacts. Toxic Releases query options include:

Mapping Applications

Envirofacts provides users with the ability to generate a variety of maps using data from the Envirofacts Data Warehouse, as well as other data sources. Using these applications, you can map a specific geographic area and determine the environmental conditions and features of that area, use GIS functionality to examine spatial data at the county, state, and national level, display multiple spatial layers, and query single Envirofacts points. Mapping applications available from Envirofacts include: EnviroMapper, EnviroMapper for New York City Response, Window to My Environment, and OpenLink. Go to TopTop


The Brownfields Initiative, which began in 1995, provides up to $200,000 for two years to qualified states, cities, towns, counties, and tribes with the goals of identifying brownfields sites and facilitating their cleanup. The Brownfields Initiatives program attempts to revitalize these areas economically and environmentally. Read about Brownfields Pilot projects.Go to TopTop

EPA - New York City Response

The U.S. Environmental Protection Agency (EPA) and other federal, state and local agencies have collected extensive environmental monitoring data from the World Trade Center site and nearby areas in Manhattan, Brooklyn and New Jersey. Since September 11, EPA has taken samples of the air, dust, water, river sediments and drinking water and analyzed them for the presence of pollutants that might pose a health risk to response workers at the World Trade Center site and the public. Read more about the monitoring data in NYC. Go to TopTop
