The Agency for Toxic Substances and Disease Registry (ATSDR) created the ATSDR Brownfields/Land Revitalization Action Model as a tool to help you make changes were you live — like fixing up old buildings or cleaning up empty lots. By teaming up with other people — like neighbors, officials, developers, and community supporters — you can work together to make lasting improvements in your community. This toolkit will help you learn how to use the Action Model.
