Welcome to the

Serving the groundwater industry since 1948.

Who we are:

The California Groundwater Association (CGA) is a non-profit organization representing all segments of the groundwater industry in California. 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.


It appears there are currently emails circulating from groups claiming to offer online continuing education classes that are accepted in all 50 states. THESE ARE SCAMS! These are from individuals trying to take advantage of people during the COVID-19 outbreak. Please check with the state agency or your staff (contact information at bottom of page) before accepting, applying, or giving money to these folks. ALWAYS confirm with the state association that it’s legit.
