State hydrologist Mike Gannon warns that a request to export water from Iowa’s Jordan aquifer to other states would set a bad precedent.

Pattison Sand Co. of Clayton, IA wants to pump water from the Jordan Aquifer and export it to other states.  Gannon says that while the proposed pumping operation will be offset by high recharge rates in north-eastern Iowa, allowing a public resource to be used for private profits may draw other operations to Iowa. Additional pumping from the Jordan aquifer may threaten water supplies for cities across Iowa as drought and severe weather conditions become more common.

The Jordan aquifer is used by multiple cities for drinking water, including both Iowa City, and Des Moines.  The water level for the aquifer has already decreased by up to 150 feet in parts of Iowa because of heavy use, and recharge would potentially take around 300,000 years.

The proposal has been opposed by the Sierra Club and has been already been denied three times by Iowa’s Department of Natural Resources. There is another hearing for the case spanning November 9th, and 10th after Pattison Sand Co. appealed a previous ruling.
