Public Notice
Army seeks public input on the former
Badger Army Ammunition Plant (AAP)
Groundwater Remedial Investigation / Feasibility Study (RI/FS)
The Army, in consultation with the Wisconsin Department of Natural
Resources (WDNR) invites the public to provide their comments on the
Groundwater RI/FS for the former Badger AAP.
Groundwater investigation activities at the former Badger AAP
began in 1980. Site-wide groundwater investigations identified four
groundwater plumes:
• Propellant Burning Ground (PBG) Plume,
• Central Plume,
• Deterrent Burning Ground (DBG) Plume, and
• Nitrocellulose Production Area (NC Area) Plume.
Groundwater is contaminated by chlorinated solvents and explosives.
Soil remedial actions addressed the source areas to the maximum extent
possible. The Army has received site closure from the WDNR on all soil
related investigations and remedial actions. Two previous RI/FS have
addressed groundwater but none resulted in a proposed plan or decision
document, or moved to the remedial design stage of the Comprehensive
Environmental Response, Compensation, and Liability Act (CERCLA).
This RI/FS provides the results of the Army’s investigation to determine
the nature (types) and extent (vertical and horizontal boundaries) of
contamination and the study of remedial alternatives to address the
contamination that exceeds risk-based criteria for each individual plume.
In the remedial investigation or RI, the Army characterizes the site and
identifies the contaminants, explaining what has happened over time.
In the feasibility study or FS, the Army presents the different remedial
alternatives it has identified to address any unacceptable risk to human
health. The Army evaluates these alternatives using EPA’s nine criteria in
accordance with CERCLA.
