We report on the design and operation of a low-background single-phase liquid argon detector that was built to study the Ar-39 content of this underground argon. Underground argon from the Kinder Morgan CO2 plant in Cortez, Colorado was determined to have less than 0.65% of the Ar-39 activity in atmospheric argon, or 6.6 mBq/kg specific Ar-39 activity.
