The City of Ann Arbor operated a landfill at Platt and Ellsworth roads through the early 1990s.
The facility is now closed, but as of 2015 the Michigan Department of Environmental Quality still requires monitoring of environmental contamination at and near the site.
According to the City of Ann Arbor, for many years the landfill has had a plume of 1,4 Dioxane and Vinyl Chloride contamination offsite primarily in Southeast Area Park, northeast of the landfill. A slurry wall was constructed along approximately 80% of the boundary of the landfill to eliminate groundwater passing through the landfill and three purge wells were used to attempt to capture the offsite contamination.
