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.”
