Work on Basin H is underway! Currently, we are cleaning MMSD sewers in N Humboldt Blvd. and E Vienna Ave. There will be temporary traffic control, such as lane and parking restrictions and barricades, so please take notice. To learn more about the project status, watch the October 2022 Basin H Update video.
To learn more about the Basin H project and the planned clean-up of contaminated material in the Milwaukee River Greenway watch the Waterway Restoration Partnership May 9, 2022, virtual meeting.

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 North Humboldt Boulevard between East Capitol Drive and East Locust Street 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.
This project is part of a larger initiative to clean up the Milwaukee Estuary Area of Concern (AOC). Learn more about the AOC by watching this John Gurda video or visiting the Wisconsin Department of Natural Resources website here.
A qualified contractor will use powerful vacuum equipment and specially outfitted trucks with sealed liquid containers to complete the cleaning process through manholes located along North Humboldt Boulevard and in Kern and Pleasant Valley Parks. Precautions will be made to secure the work sites and prevent any sediment from migrating further downstream.
This project will follow a USEPA approved remediation work plan which consists of the following steps:
Typical vacuum equipment used to remove PCB’s from sewers.
Trucks with sealed liquid container.
Milwaukee County Parks will continue to be open to the public, but there will be limited traffic and trail impacts during the project.
