Question

how does underground water get replenished​

Answer 1

Groundwater supplies are replenished, or recharged, by rain and snow melt that seeps down into the cracks and crevices beneath the land's surface.

Answer 2

Answer:

Groundwater replenishment happens through direct recharge and in-lieu recharge. Water used for direct recharge most often comes from flood flows, water conservation, recycled water, desalination and water transfers. Two recharge methods are used: direct spreading and aquifer injection.
