Investigation of hydrogeologic conditions and ground water flow in the Boise Front geothermal aquifer (executive summary). Research report 2003-07 Item Info

This report summarizes a study of hydrologic conditions in the Boise Front geothermal aquifer system conducted for the City of Boise, Idaho and the National Renewable Energy Laboratory. The summary is based on the following two reports: (1) "Hydrogeologic conditions in the Boise Front geothermal aquifer" (Petrich, 2003). (2) "Simulation of ground water flow in the Boise Front geothermal aquifer (Zyvoloski et al., 2003). This study arose from a request by the City of Boise to expand current levels of production (with corresponding re-injection) under existing water right permits. This production increase would be used to meet projected demand for geothermal heat in the downtown area. The proposed production increase led to concerns about possible water level and/or temperature changes in the geothermal system by other users. The City of Boise and other major users therefore sought additional hydraulic, thermal, and hydrogeologic information about the geothermal aquifer system, and the development and implementation of a monitoring plan. The purpose of this study was to provide insight and tools for the long-term management of the Boise geothermal aquifer system. Specific objectives included the following: (1) Review and refine the current conceptual understanding of the Boise Front geothermal aquifer system. (2) Consolidate existing hydrogeologic and production data into a single database. (3) Conduct a mass measurement of water levels and/or pressures in selected geothermal wells throughout the system. (4) Construct a numerical model capable of simulating hydraulic heads and water temperatures in the Boise Front area. (5) Calibrate the model on the basis of hydraulic head and temperature observations using methods that quantify calibration confidence. (6) Evaluate potential hydraulic and thermal effects of increased production and re-injections by the City of Boise on wells in the downtown Boise-Table Rock, Harris Ranch, and Stewart Gulch areas.
