===National Priorities List inclusion===
In 1987, the [[Environmental Protection Agency]] (EPA) placed the Milan Army Ammunition Plant on the [[National Priorities List]].  [[Contamination]] of the city's [[groundwater]] in the Memphis Sand Aquifer of 2,4,6-[[trinitrotoluene]] (TNT) and [[RDX]] was of particular concern.<ref name="epa">{{cite web|url=http://www.epa.gov/region4/superfund/sites/fedfacs/miarmyamotn.html |title=Milan Army Ammunition Plant |publisher=EPA.gov |access-date=July 4, 2013}}</ref>

In 1989, the EPA, United States Army and [[Tennessee Department of Environment and Conservation]] (TDEC) signed a Federal Facilities Agreement (FFA) for the site. The FFA ensures that the parties would fully investigate [[Environment (biophysical)|environmental]] impacts associated with past and present activities at the installation and complete appropriate cleanup actions through established schedules and enforceable milestones.<ref name="epa" />

In the early 1990s, the United States Army financed the relocation of the city's drinking water well field.  The United States Army implemented institutional controls to prohibit groundwater use in contaminated areas.<ref name="epa" /><ref name="army cleanup">{{cite web |url=http://aec.army.mil/usaec/cleanup/TN-Milan.pdf |title=Army Defense Environmental Restoration Program - Installation Action Plan FY2012 |publisher=Army.mil |access-date=July 4, 2013 }}{{dead link|date=April 2025|bot=medic}}{{cbignore|bot=medic}}</ref>

In 2010, the third Five-Year Review found that the cleanup activities were protecting people and the environment.<ref name="epa" />

The [[velocity|velocities]] of the plume vary, but the direction is primarily North towards the Rutherford Fork of the [[Obion River]] and from the Northwest boundary towards the city.<ref name="epa" /><ref name="army cleanup" /><ref name="ME cleanup" />

The long-term care of the groundwater contamination plume is expected to last through 2075 when contamination is expected to be below the EPA required two [[parts-per notation|parts per billion]].<ref name="ME cleanup" />
