Year: 1975 Economically feasible uses for geothermal heat at temperatures too low for conventional electrical power generation at present are delineated. Several geothermal resource areas in northern California that have development potential are described, and applications of the heat found in each area are suggested. Plates are included of the following field study areas: the east side of the Sierra-Cascade Range north of Bishop, and the northern Coast Range from San Francisco Bay to Clear Lake. The counties included in the study area are Mo doc, Lassen, Sierra, Plumas, Placer, Alpine, Mono, Mendocino, Lake, and Sonoma.

Year: 1978 Some of the areas of hot water, such as Hoosevelt, Pavant-Black Rock, and Cove Fort-Sulphurdale, probably have a potential to produce electricity. But the many areas of warm and hot water whose temperatures are too low to produce electricity may still have their waters utilized for space heating, as is planned for Monroe, for greenhouses, and for the processing of farm produce. In this report are tables that give records of about 1500 thermal springs and wells: 65 yield hot water, more than 400 yield warm water, and more than 1000 yield slightly warm water. The records include location, ownership, temperature, yield, depth (of wells), geologic unit, and some chemical analyses Title: Thermal Waters of Utah Author: Goode, H.D.

  	Citation × Citation Citation Abstract Copy Title: Non-Electric Applications of Geothermal Energy in Six Alaskan Towns. Final Report, October 1976--November 1977 Author: Farquhar, J. Year: 1977 The potential for direct (non-electric) utilization of local-gradient geothermal energy in six Alaskan towns is summarized. A major objective of this study was to stimulate development and Use of the geothermal resource provided by the earth's average thermal gradient, as opposed to the few anomalies that are typically chosen for geothermal development. Hence, six towns for study were selected as being representative of remote Alaskan conditions, rather than for their proximity to known geothermal resources. The moderate-temperature heat available almost everywhere at depths of two to four kilometers into the earth's mantle could satisfy a major portion of the nation's heating requirements--but the cost must be reduced. It is concluded that a geothermal demonstration in Nome would probably be successful and would promote this objective Title: Non-Electric Applications of Geothermal Energy in Six Alaskan Towns.

  	Citation × Citation Citation Abstract Copy Title: Beneficial Uses of Geothermal Energy Description and Preliminary Results for Phase 1 of the Raft River Irrigation Experiment Author: Schmitt, R.C. Year: 1977 The first phase of an experiment using geothermal water for irrigation is described and preliminary results are discussed. The water was from a moderate temperature well, having salinity of about 2000 ppM, and is considered characteristic of the types of geothermal fluids that will be obtained from the young volcanic/young sediment formations of the northern intermountain west. The activity was completed at a location adjacent to ERDA's Raft River Geothermal Project in southern Idaho. About 12.5 acres, of which part had no previous cultivation, were subdivided by crops and irrigation practices for investigation with the geothermal water and a control comparison water from the relatively pure Raft River. Flood and sprinkler application techniques were used and wheat, barley, oats, grasses, alfalfa, potatoes, and garden vegetables were successfully grown. An accompanying experiment evaluated the behavior of an established alfalfa crop located nearby, when most of the irrigation water was geothermal. The experiment addressed heavy metal uptake in plants, plant fluoride retention and damage, plant tolerances to salts, soil alterations and other behavior as a result of the geothermal fluids, all of which were largely believed to eliminate geothermal water from contention for crop growing utilization. Not all analyses and results are complete in this reporting, but first results indicate no apparent difference between the geothermal watered crops and those obtained using the fresh water control. Extensive chemical analyses, neutron activation analyses, and other evaluations of crop samples are discussed, and some of the findings are presented. Although evaluation of crop yields was not an objective, extrapolations from samples indicate that yield results were comparable to those commonly found in the area, and the yield varied little between water sources.
