Abstract
An aquifer test of the Prairie du Chien-Jordan aquifer was conducted in the Shakopee Mdewakanton Sioux Community located southwest of the Twin Cities metropolitan area. A well open to the Jordan Sandstone was pumped at 600 gallons per minute for 57 hours. Drawdown was monitored in three observation wells located near the pumped well. These wells were open to: (1) the Jordan Sandstone, the principal unit of the aquifer; (2) the Prairie du Chien Group, a secondary, carbonate-rock unit of the aquifer; and (3) a confined, glacial-drift sand aquifer. Test results indicate that the Jordan Sandstone had a transmissivity of 6,267 ft2/d, a storativity of 1.193 x 10-4, a horizontal hydraulic conductivity of 31 ft/d based on a saturated thickness of 204 ft, and a ratio of vertical to horizontal hydraulic conductivity of 5.29 x 10-4. The pumped well was hydraulically connected to the Prairie du Chien Group observation well. No drawdown was observed in the observation well completed in the confined, glacial-drift sand aquifer; thus, a hydraulic connection of this observation well to the pumped well was not indicated.
