DNR to hold public information meetings on the Jordan aquifer DNR to Hold Public Information Meetings on the Jordan Aquifer MEDIA CONTACTS: Bob Libra, DNR Iowa Geological and Water Survey, at (319) 335-1575 or [log in to unmask]<mailto:[log in to unmask]> IOWA CITY — DNR will hold two public information meetings to present the findings of a year long study of the Jordan aquifer – a drinking water source for approximately 300,000 Iowans that is widely used for industrial water supplies. The meetings will take place in areas where the aquifer is heavily used and has seen significant declines in water levels. However, the studied and modeled areas cover virtually all of the state, as the Jordan is Iowa’s most widely developed deep groundwater source. The first meeting is scheduled for the Cedar Rapids area from 1 to 3 p.m., Dec. 10, at the Linn County Conservation Board’s Wickiup Hill Learning Center, 10260 Morris Hills Road in Toddville. The second will be Dec. 15 near Fort Dodge from 10 a.m. to noon at the Webster County Conservation Board’s Bob Heun Shelter at JFK County Park, 1415 Nelson Ave. DNR staff will present the Iowa Geological and Water Survey’s recently completed regional groundwater study and predictive model for the Jordan (Cambro-Ordovician) aquifer. The groundwater model uses information from thousands of well records, hundreds of water production tests, current and historic water levels, and water withdrawal records dating back 100 years. The completed and tested model can estimate changes in water levels decades into the future for a wide range of anticipated or possible future demands. “Assuring the long-term sustainability of the aquifer is critical. The Jordan aquifer is the most dependable, productive and widespread source of groundwater in Iowa, underlying most of the state,” said Bob Libra, who serves as Iowa’s state geologist. “However, the aquifer is relatively deep over much of the state, and its rate of replenishment or recharge is exceeded by the overall pumping rate. As a result, water levels have declined by as much as 250 to 300 feet since it was first used in the 1800s.” While most of the aquifer has experienced a smaller reduction in the water level, the model forecasts areas where significant declines can be anticipated over coming decades, which is a needed tool for water planners.
