Water-bearing formations are aquifers. An aquifer is a layer of earth that stores groundwater and allows it to move enough to supply a well. The important idea is that it can both hold water and transmit it through interconnected pores or fractures. Porosity is just the amount of void space in the material, which helps determine how much water could be stored, but it doesn’t guarantee flow. Sediments describe the loose materials that make up the ground, not the specific capability to yield groundwater. Bedrock is the solid rock beneath soils and sediments and may or may not transmit water depending on fractures and permeability. So, the term that properly names water-bearing formations is aquifers.
