Understanding what lies beneath the ground in cities is important for protecting our water resources. However, studying the subsurface in urban areas is difficult because buildings, roads, and electrical systems can interfere with scientific equipment. In this project, we used two types of electrical geophysical tools to 'see underground' in Shelby County, Tennessee. One tool, called Electrical Resistivity Tomography (ERT), gives a detailed picture near the surface. The other, called Transient Electromagnetics (TEM), can see deeper underground but is more sensitive to electrical interference from urban environments. We tested both tools in different locations: near a river, in a field, and next to a busy road. We found that each method works best in different settings, and using them together gave us the most complete view of underground features like ancient river channels and breaks in protective clay layers. This information can help improve how we manage groundwater and protect it from contamination in growing cities.
