Will Iowa have enough water? by Perry Beeman

Iowa may have trouble coming up with enough water to fill taps and meet industrial needs in coming decades.

The Iowa Department of Natural Resources is worried that underground water supplies in some areas might not be able to quench the future thirst created by urban sprawl and the state’s growing biofuels industry.

Geologists already wonder if the Cedar Rapids-Iowa City area, one of the fastest growing parts of the state, will have enough water to go around decades from now. That’s especially true of Marion, which may have to find new sources or pipe in water from another system, said state geologist Robert Libra.

Those concerns are emerging from the DNR’s four-year-old effort to inventory and measure how much water remains in Iowa’s network of aquifers. It’s the first large-scale effort of its kind, and one that some say is long overdue.

“We can now look 20 to 30 years into the future with the models we are developing,” Libra said. “We’re telling people, ‘You may not be able to produce the water you’re counting on.’ It’s a call to take a smart tool and plan. These towns need water. The towns need businesses. The businesses need water.”

Iowa State University geologist William Simpkins said Iowa has the poorest water planning in the Midwest. What plans the state does have haven’t been fully updated since 1985.
And that could be a problem as water usage rises for ethanol, geothermal systems, growing towns and new industries, Simpkins said.

“One of the problems with Iowa is, since we don’t have a lot of huge, huge industries that are really stressing the aquifers, we’ve fallen into a malaise and don’t think we have to worry about it.”
