Where is water used for drinking most likely to come from?

in my country the water comes from the mountain region. But the water drinking most likely comes from river or sea.

Your drinking water comes from natural sources that are either groundwater or surface water.

Explanation:

Groundwater comes from rain and snow that seeps into the ground. The water gets stored in open spaces or pores or in layers of sand and gravel known as aquifers. We use water wells or springs to harvest this groundwater.
