Cleanup activities at a site include removals, studies, remedy selection, remedy design, remedy implementation, and post-construction activities. The completion of each activity enables the site to move further along in the cleanup process.

-Post-Construction – Superfund Post-Construction is a cleanup phase where several activities are generally undertaken at sites following the construction of response actions. These activities include operation and maintenance and long-term response actions; five-year reviews, close-out reports, and deletion from the NPL. The goal of Superfund Post-Construction is to ensure that response actions provide for the long-term protection of human health and the environment.
