Advances in geothermal technologies and their usage created the need for a specific voluntary certification designation for geothermal drillers. NGWA responded to this need with the designation of Certified Vertical Closed Loop Driller (CVCLD).
The CVCLD is considered an independent designation from the CWD or CWD/PI. The designation reflects an individual who has passed a written exam administered by NGWA that evaluates an individual’s knowledge of the skills and competencies associated
with constructing a loop well.
