This week’s On the Radio segment looks at recent news surrounding Iowa’s Jordan Aquifer, which is being depleted faster than it can regenerate itself. Listen to the audio below, or continue reading for the transcript.

Transcript: Jordan Aquifer

Increased water demand in Iowa is straining one of the state’s largest underground aquifers.

This is the Iowa Environmental Focus.

The Des Moines Register reports that the Jordan Aquifer – which supplies about half a million Iowans with water – is being depleted faster than it can regenerate itself.

Last year Iowa drew nearly 26 billion gallons from the aquifer which is a 72 percent increase since the 1970s. Nearly 200 businesses, municipalities, universities, and other entities tap into the Jordan Aquifer with about 345 wells across the state. Parts of southwest Iowa need to drill as deep as 2,500 feet underground to extract water from the aquifer.

This increase in water usage can partially be attributed to Iowa’s biofuels industry, which requires large quantities of purified water during the production process. Roughly 15 percent of Iowa’s aquifer demand is for biofuel production with some facilities using as much as 200 million gallons of water each year.
