  	Citation × Citation Citation Abstract Copy Title: Investigations of the Dunes Geothermal Anomaly, Imperial Valley, California: Part 1. Geochemistry of Geothermal Fluid Author: Coplen, T.B. Year: 1974 A geothermal test borehole, DWR Dunes No. 1, was drilled in the Dunes geothermal anomaly by the State of California Department of Water Resources. Water samples from this geothermal system were collected from perforations at 109 and 260 meters depth. These water samples were analyzed for chemical and isotopic composition. These tests indicate that the source of the geothermal fluid is partially evaporated Colorado River water. An investigation of chloride/bromide ratios was used to determine the source of the salt in the geothermal fluid from Dunes. The result may suggest that the salt in the Salton Sea geothermal system and in the Dunes geothermal anomaly is derived from the Colorado River and that this water has not done any leaching or been mixed with water from other sources. It was determined that further geophysical Studies (gravity, seismic refraction, electrical resistivity, and magnetotelluric sounding) are needed to locate the reservoir of geothermal fluid in the Dunes system Title: Investigations of the Dunes Geothermal Anomaly, Imperial Valley, California: Part 1.

Year: 1980 The completed geochemical analysis of groundwater in the Pine Creek area for evaluation of the geothermal potential of this location is presented. Also included is an environmental constraints analysis of Pine Creek noting any potential environmental problems if a geothermal system was developed onsite. Design of a geothermal system is discussed for site-specific applications and is discussed in detail with equipment recommendations and material specifications. A preliminary financial, economic, and institutional assessment of geothermal system located totally on Union Carbide property at Pine Creek is included.
