Streams flowing across an alluvial fan would have the best chance of surface water infiltrating into the local groundwater system because alluvial fans are made up of porous materials such as sand, gravel, and silt, which allow for the easy passage of water. Additionally, the gradient of the land on an alluvial fan is typically gentler than other options, allowing for water to flow more slowly and sink into the ground instead of running off quickly.
