Superfund Site Profile
The Joliet Army Ammunition Plant Load-Assembly-Package (LAP) Area is located 10 miles south of Joliet in Will County, Illinois. It covers 22 square miles of a former Army munitions facility. From the early 1940s through 1977, high explosive artillery shells, bombs, mines and small arms ammunition were loaded, assembled and packaged on site. Following cleanup, the site’s long-term remedy is in place. Groundwater monitoring is ongoing. The site is now in reuse.
The former Joliet Army Ammunition Plant – one of the largest and most productive ordnance complexes ever built – has a new identity as the Midewin Tallgrass Prairie, Abraham Lincoln National Cemetery, Prairie View Landfill and several manufacturing and distribution business parks. After extensive environmental investigation and cleanup, and close collaboration between federal, state and local governments, community groups and the private sector, cleanup finished in early 2008 – three years ahead of schedule.
