Resource provided by UW-Madison Robinson Map Library. This dataset includes active and inactive solid waste landfills and known historic waste site points. A point showing the general location of the landfill or polygon centroid can be found in the dataset called Solid Waste- Landfills and Historic Waste Site Points. At this time, most of the landfills and known waste sites’ boundaries are mapped as a polygon. The remaining sites are in the process of being mapped. This dataset represents the latest updates and is updated frequently.
