Idaho is a Geo Thermal State with public and private resource wells. In order to be considered a geothermal resource well the bottom temperature must be 85*-21*F and are called LTG (low temperature) wells. A bottom temperature of more than 212* in a well is considered a Geo Thermal Resource well.
Geo Thermal Resource wells are subject to strict placement, drilling, maintenance and abandonment regulations and must carry a bond of $5,000 to $20,000 renewed annually to insure that no contamination with ground water from different aquifers effect potable water.
