Data Sources/Query Forms

Here are links to the most requested environmental data. Often, more than one site provides links to the same data. In such cases, I have linked to the sites that have the easiest interfaces. There are a number of websites that let you search for hazardous sites, then generate a map that shows poverty levels, minority populations, schools, etc. in the surrounding area.

  • Envirofacts 
    A single point of access to select US EPA environmental data. Data coverage includes Superfund data, Safe Drinking Water Info, Hazardous Waste Data, Toxics Release Inventory, Water Discharge Permits, Air Releases and Grants Information.

  • CERCLIS (Superfund) Hazardous Waste Sites
    Locate Superfund hazardous waste sites by state, county or city. 

  • AIRData (EPA) Air Pollution Data 
    AIRData gives you access to air pollution data for the entire United States. Want to know the highest ozone level measured in your state last year? Ever wonder where air pollution monitoring sites are located? Are there sources of air pollution in your town? This is the place to find out! AIRData creates custom reports using criteria that you specify, displays standard maps of the United States, and provides names of people to contact.

  • Maps on Demand

    These web-based mapping applications generate maps that display environmental information for the entire United States. MOD accesses data available through the Envirofacts Warehouse.

  • Superfund Query Form

    The Superfund Query Form allows you to retrieve data from the Comprehensive Environmental Response, Compensation, and Liability Information System (CERCLIS) database in Envirofacts. Specify a facility by using any combination of facility name and geographic location. You may also select an output option.

    This great Superfund Page offers 2-Page descriptions of every site on the NPL. Good information, including the date of addition to NPL.

    One of the simpler EPA databases. Allows you to search for information by zip code. User chooses 1 of 4 databases. Data offered includes hazardous waste, environmental conditions/trends, maps, and watershed conditions.

  • Chemical Score Card

    Another simple database that allows you to search by zip code. Created by the Environmental Defense Fund, this site neatly ties together EPA data, makes it easy to search, and presents it in a user-friendly, yet detailed and powerful format. A MUST SEE.

  • National Environmental Scorecard

    The League of Conservation Voters has compiled this scorecard since 1970 and now it is available to you via the Internet. The Scorecard provides a score for all members of Congress based on their voting record on environmental legislation. You can search for legislators who represent you or those who represent your state, or view all Senators and Representatives. The Scorecard also allows you to search by various criteria such as gender, party affiliation and region or state a Congressman comes from.


    RTK NET was started in 1989 in support of the Emergency Planning and Community Right to Know Act (EPCRA), which mandated public access to the Toxic Release Inventory. It is operated by two nonprofit organizations--OMB Watch and The Unison Institute--and funded by various government agencies and foundations. Good general links, as well as excellent links to data sources.
