Borehole heat exchanger temperature at differing lithological units

This data is temperature measurements as measured by thermocouples attached to the u-tube of a central single borehole heat exchanger in a larger 144 well field. Thermocouples were installed at 50 foot intervals from 50 to 400 feet below ground surface. The thermocouple measure the temperature at the interface of the grout and incoming water side of the u-tube.
