Low Temperature (<90°C) Geothermal Wells and Springs

Data includes available information on location, temperature, flow rate, acidity (pH) and Total Dissolved Solid (TDS) content of 2,071 wells and springs which are representative of 1,168 low-temperature geothermal systems identified in 26 States. Names used in this table are generally those used on the state geothermal resource maps. If the site is unnamed, a nearby feature is usually given for reference. The site is identified as a spring or well, and alternate names are sometimes given in parentheses. The data is obtained from the United States Geological Survey (U.S.G.S.) Open-File Report 83-250 (Table-1) titled Low-Temperature (Less Than 90°C) Geothermal Systems in The United States; Reference Data for U.S.G.S. Circular 892. The report was originally published in 1982 and updated in 2015 (report forthcoming from USGS). Detailed geochemistry data and reservoir temperature estimates (from different geothermometer calculations) are also available in the original report.
