A 2012 report titled The Patterns of Pollution identified several areas across the Atlanta metro with high numbers of marginalized residents and high risk of environmental hazards, or ‘environmental justice hotspots.’ More than a decade later, scholarly and community interest highlighted the need for a replication of the report, which this thesis undertakes. While the replication identified a 210% growth in hotspots associated with major transportation routes and industrial zones, the methods for mapping these hotspots, and the concept of environmental justice hotspots in general, became their own object of study. Therefore, this thesis seeks to rethink what the concept of environmental justice hotspots accomplishes through their mapping. By combining an exploratory cartographic analysis with interviews undertaken with environmental justice practitioners, this thesis identifies the strengths, weaknesses and opportunities that arise from mapping environmental justice hotspots. Ultimately, meaningful engagement with community perspectives can produce more responsible mappings of environmental injustices.
