Our members include water well drilling and pump contractors, hydrogeologists, engineers, hydrologists, manufacturers and suppliers, government employees and others working in the groundwater field. CGA was founded in 1948 and was known as the Associated Drilling Contractors (ADC) until 1986 when the name was changed to emphasize the organization's involvement with all aspects of the groundwater field.
