The document outlines various case studies involving 3-D printed conceptual site models to represent geological and environmental conditions at different sites. Case studies include models for the EPA Region 4 NAPL and geology, distribution of zero-valent iron in clay till, and the 68th Street Landfill Superfund site. These models help visualize complex data in a tangible format, aiding in site assessment and management.
