Water drawn from an unconfined aquifer is called what?

Groundwater is water that sits underground in the pore spaces of soil and rock. In an unconfined aquifer, the top of the saturated zone is the water table and there isn’t a confining layer above it, so recharge mainly comes from rainfall seeping down. Water drawn from that layer through a well is groundwater. This is distinct from surface water (rivers, lakes), rainwater (precipitation), or sewage (wastewater).
