Title: Ground-water temperature of the Wyoming Quadrangle in central Delaware, with application to ground-water-source heat pumps. Water-resources investigations (final)

Technical Report ·
OSTI ID:5321740

Ground-water temperature was measured during a one-year period (1980-81) in 20 wells in the Wyoming Quadrangle in central Delaware. Data from thermistors set at fixed depths in two wells were collected twice each week, and vertical temperature profiles of the remaining 18 wells were made monthly. Ground-water temperature at 8 feet below land surface in well Jc55-1 ranged from 45.0F in February to 70.1F in September. Temperature at 35 feet below land surface in the same well reached a minimum of 56.0F in August, and a maximum of 57.8F in February. Ground-water-source heat pumps supplied with water from wells 30 or more feet below land surface will operate more efficiently in both heating and cooling modes than those supplied with water from shallower depths.
