Environmental Bureau of Investigation
A citizen-based investigative outfit, EBI investigated pollution sources and, when necessary, sought those responsible. EBI's methods included investigation, prosecution, exposure and education. The goals of EBI were to investigate and prosecute environmental crime, assist individuals and groups in their fight against polluters, develop public education tools to empower citizens to stop pollution, and publish and publicize information on pollution sources and sites.
EBI continues to maintain its web-based Citizens Guide to Environmental Investigation and Private Prosecution. You can view the guide here: http://www.e-b-i.net/ebi/guide/toc.html
