NATIONAL POLLUTION PREVENTION CENTER FOR HIGHER EDUCATION
This site run by the University of Michigan is designed with students, faculty and professionals in mind, but it's useful to anyone who needs research materials. The nicely organized Resource section is a good first stop. Free information on topics that include corporate environmental strategy, agriculture and coastal zone management is available as downloadable files (which you have to read using free Adobe Acrobat software); for a fee you can get printed copies. The NPPC also offers detailed information on its projects and a long list of environmental links.

GROUND-WATER REMEDIATION TECHNOLOGIES ANALYSIS CENTER

Notices about conferences on ground water and related subjects are provided, as is a toll-free number to report ground-water contamination.
