Post-Database Construction (not currently funded)

• Evaluation of geothermometry
• Construct better geologic models to help ID new
  and blind target areas
• Preliminary and full assessments

Summary
350 known geothermal systems in NV gt30 do
not have modern, complete water analyses From
?2700 digitized springs from 7.5 Quads -
chemistry and temperature of ?1029 thermal
springs is unknown On-going work funded by DOE
to compile data, fill in some gaps update
