your-state.xls - TRI data in spreadsheet format for your-state(s).
EPA TRI Explorer report for your-state(s) in PDF format.
RTK Net TRI data for your-state(s) in low level of detail.
RTK Net TRI data for your-state(s) in high level of detail.
Shapefiles of various nationwide base layers in the
"shapefile-base-maps" directory. These include:
U.S. state boundaries
U.S. major rivers
U.S. major cities

fields.txt - this is a list of the EPA provided
data field names and the names that we used when
converting the data files to GIS shapefiles.
A good resource for free map layers such as local streets,
county boundaries, streams, census tracts and much more is:
Note: Be sure to print out the instructions on the download
