The Milwaukee Die Cast Site is an abandoned property (owner deceased) in a mixed residential, commercial, and industrial area in the City of Milwaukee. The building, sub-slab soil, surrounding soil, and groundwater are contaminated with polychlorinated byphenols (PCB) and chlorinated solvents (PCE and TCE). Despite a fence around the property, there is frequent trespassing at the Site. PCBs have also been identified in the sanitary and stormwater sewer systems servicing Milwaukee Die Casting. EPA’s Site Assessment confirmed contamination warranting a time-critical removal action at the facility and in the storm sewer, but not in the sanitary sewer system.

Pharmacia LLC and Fisher Controls International LLC agreed in March, 2013 to conduct a time-critical removal action at the Site, with EPA oversight, pursuant to an Administrative Order on Consent. The Redevelopment Authority of the City of Milwaukee (RACM) assumed ownership of the Site to facilitate the clean-up. Site security and stabilization measures began on May 17, 2013. The property was disconnected from the City storm sewers on September 18, 2013. The building was demolished in spring and summer, 2014. The underground tunnel systems were removed during the summer and fall of 2014. Excavation of contaminated soil began in April, 2015. Excavation activities and installation of a protective cap are expected to be completed by September, 2015. The Site will be a grassy lot ready for low occupancy redevelopment upon completion of the Removal Action.
Specific information about the removal activities is available in Monthly Progress Reports (Documents Section).
