Protecting and Providing Groundwater for All of California

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.

Groundwater Awareness Week

As a NGWA Affiliate Organization member, we are proud to partner with NGWA to share with you that Groundwater Awareness Week (GWAW) is taking place March 9-15, 2025!

This annual event highlights the responsible development, management, and use of groundwater, the event is also a platform to encourage yearly water well testing and well maintenance, and the promotion of policies impacting groundwater quality and supply. Groundwater advocates across the state and country also use GWAW to highlight local water issues in their communities.

NGWA and its partners will be focusing their advocacy on promoting professional opportunities in the groundwater industry. According to the American Geosciences Institute, nationally there are more than 135,000 open positions in the industry now, which is far too high to keep up with consumer demand.
