Final answer:
Large metropolitan areas get most of their fresh water from surface sources such as lakes, rivers, and reservoirs, while small/rural areas get most of their fresh water from groundwater that is pumped from a well.
Step-by-step explanation:
Large metropolitan areas get most of their fresh water from surface sources such as lakes, rivers, and reservoirs. These sources can be near the urban areas or far away. Water suppliers procure and treat the water they provide.
On the other hand, small/rural areas get most of their fresh water from groundwater that is pumped from a well. Wells provide water from aquifers, which are natural water reservoirs under the earth's surface.
