Type of groundwater source.

Other - Other groundwater source.

Spring - A spring is a point where groundwater flows out of the ground, and is thus where the aquifer surface meets the ground surface.

When they leave the ground they may forms pools or streams.

Surface - All water naturally open to the atmosphere (rivers, lakes, reservoirs, ponds, streams, impoundments, seas, estuaries, etc.) and all springs, wells, or other collectors directly influenced by surface water.

Unknown - Groundwater source type is unknown.

Well - A pit, hole, or shaft sunk into the earth to tap an underground source of water.

Wellfield - An area containing more than one pumping well that provides water to a public water supply system or single owner.
