EPA Data Finder. Data Finder is a single place to find EPA's data sources so people can access and understand environmental information. All of the data sources are available on the Internet and have been organized by topics such as air, water, and chemicals. In the near future, EPA will use Data Finder to discover raw data and make it accessible via Data.gov, a federal site that helps people find, download, and use datasets that are generated and held by the Federal Government. This version of Data Finder provides an initial collection of EPA's data sources. View and use at http://www.epa.gov/datafinder/
