- In 2008, cleanup of residential and commercial properties in the Box was certified complete. Over 3,000 properties have been cleaned up to date. Many local communities cooperated in this massive, multi-agency effort to test, partially remove, and cap metals-contaminated soils.
- Blood-lead levels in children in the Box are down.
- Trees, grasses, and shrubs are flourishing and wildlife has returned to hillsides in the Box.
- Hundreds of yards are cleaned up every year in the Basin. Property sampling continues and results are provided to property owners and to those interested in real estate transactions.
- Local workers are being hired to do yard cleanup work.
- Agencies are continuing to look for secure places, called "repositories," to put contaminated materials from yard cleanups.
- By the end of 2006, EPA had transferred about 1800 acres of Box property to the State of Idaho to facilitate economic development.
- Thousands of people are enjoying the 72-mile Trail of the Coeur d'Alenes, which was completed in 2005. This project returned land to productive use, providing a safe recreational trail for local residents and tourists.
- Recreational areas along the Spokane River are being cleaned up.
- Nearly 400 acres of safe feeding habitat for wild birds and other wildlife is being created.
