Watch: Mariah Bonham | Aquifer Access (3:47 mins)
Mariah Bonham, Groundwater Protection Coordinator, explains why finding abandoned wells is so important to protecting the Edwards Aquifer.

Vocabulary

Sinkhole

A natural depression or hole formed by the sudden collapse of the land surface, often as a result of dissolution of underlying limestone by flowing groundwater.

Porous Rock

A type of rock with holes or openings that can hold water.

Limestone

A hard sedimentary rock. The Edwards Aquifer is made up of limestone.

Non-Point Source Pollution

Pollution that is caused by widely dispersed sources, such as runoff from urban and rural areas.

Well

A human-made hole in the ground, dug to pump out water.
