“…An aquifer test at the ATES site was used to determine that the transmissivity of the Ironton and Galesville Sandstones was approximately 690 ft 2 /d, and the storage coefficient was approximately 2.4 x 10 -5 (Miller and Delin, 1993, p. A8-A9). The vertical-to-horizontal hydraulic conductivity ratio for the Ironton and Galesville Sandstones was determined by Miller and Delin (1993) to be 0.1.…”

Shakopee Mdewakanton Sioux Community, conducted an aquifer test December 6-22, 2004, to improve definition of the hydraulic properties of the Ironton and Galesville Sandstones beneath the Shakopee Community in southeastern Minnesota. Three wells were used in the aquifer test-a production well and two observation wells, located 3,247 feet northwest of the production well and 3,049 feet southeast of the production well. The production well, completed in the Ironton and Galesville Sandstones, was pumped at about 600 gallons per minute from 10:30 a.m. on December 6, 2004, to 3:26 p.m. on December 9, 2004. Drawdown and recovery water levels were measured in all three wells. Four curve-fitting methods and two graphical methods were used to estimate the transmissivity and storage coefficient of the Ironton and Galesville Sandstones. The four curvefitting methods were the Theis, Hantush, Hantush-Jacob, and Neumann-Witherspoon methods. These methods were applied to the drawdown and residual recovery curves of the observation wells. The two graphical methods were the Cooper-Jacob method and the Theis recovery method. The Cooper-Jacob method was applied to the drawdown curve of the production well and the drawdown curves of the two observation wells. The Theis recovery method was applied to the residual drawdown curves of the two observation wells. The transmissivity estimated using the six methods ranged from 450 to 650 feet squared per day. The average transmissivity for the six methods was 540 feet squared per day. The storage coefficient estimated using the six methods ranged from 4.2 to 5.7 x 10-5. The average storage coefficient for all six methods was 5.0 x 10-5. The hydraulic conductivity was estimated by dividing the estimated transmissivity by 45 feet. The average hydraulic conductivity for the six methods was 12.1 feet per day.

“…Miller and Voss (1986) described the design of the finite-difference grid at the ATES site. Miller and Delin (1993) described (1) analysis of field observations for aquifer characterization and observation-network design, (2) preliminary model analysis to determine model sensitivity to hydraulic and thermal characteristics and to facilitate final model design, and (3) model simulations of the aquifer's thermal efficiency. Miller and De lin ( 1994) described analysis of the thermal data and nonisothermal modeling for the short-term test cycles.…”

In May 1980, the University of Minnesota began a project to evaluate the feasibility of storing heated water (150 degrees Celsius) in the Franconia-Ironton-Galesville aquifer (183 to 245 meters below land surface) and later recovering it for space heating. The University's steam-generation facilities supplied hightemperature water for injection. This Aquifer Thermal-Energy Storage system had a doublet-well design in which the injection and withdrawal wells were spaced approximately 250 meters apart. Water was pumped from one of the wells through a heat exchanger, where heat was added or removed. This water was then injected back into the aquifer through the other well. Two long-term test cycles, consisting of approximately equal durations of injection, storage and withdrawal of about 59 days, were completed. Rates of injection and withdrawal of about 18 liters per second were maintained for each long-term test cycle. Injection temperatures averaged about 108.5 and 117.7 degrees Celsius for long-term test cycles 1 and 2, respectively. Withdrawal temperatures averaged about 75 and 85 degrees Celsius, respectively. Temperature graphs for selected depths at individual observation wells indicate that the Ironton and Galesville Sandstones received, stored, and yielded more thermal energy than the upper part of the Franconia Formation. Vertical-profile plots and timegraphs during storage indicate that the effects of buoyancy flow were minimal within the aquifer.

“…However, few documented case studies other than permit applications are available in which the Basic Plume Method was used to simulate injected waste movement. In reports by Miller andothers (1986a, 1986b), who are the principal writers of the method code, the method was used to simulate the effects of injection for an injection practice in Texas. The results of using the method indicated that the estimated extent of horizontal migration was in close agreement with an estimation based on using a threedimensional numerical method.…”
