The Milwaukee Metropolitan Sewerage District (MMSD) is partnering with the United States Environmental Protection Agency (USEPA) to clean sewers located west of the Milwaukee River along Humboldt Avenue between Capitol Drive and Locust Avenue known as “Basin H”.
A 2008 investigation identified the Milwaukee Die Cast Company, located at 4132 North Holton Street in the City of Milwaukee, as the primary source of polychlorinated biphenyls (PCB’s), that were coating sewers in this area. PCB’s are legacy chemicals that were banned in 1978 which require removal to avoid problems in the future and keep our rivers and lake clean. The USEPA removed the PCB’s at the business site. MMSD is now preparing to remove and safely dispose of the PCB contamination that remains in the sewers.
