Milwaukee River Floodplains


Recent soil samples from the Milwaukee River floodplains indicate the presence of polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and heavy metals such as lead. The sampling area covers approximately four river miles on the east and west sides of the river between Estabrook Dam and the former North Avenue Dam. The floodplain is largely open to the public and contains walking trails as part of the Milwaukee River Greenway. Officials from federal, state, and local units of government are working together to ensure public health and safety and determine next steps for the ongoing river cleanup efforts.
