Who We Are

At Geoscience, we do all things groundwater. We were founded in 1978 and were the first groundwater-focused consulting firm in Southern California. From our beginning and to this day, we help water providers reliably produce groundwater supplies, sustainably manage and model groundwater, help augment groundwater supplies, and defend groundwater rights.

Since 1978 we have been at the forefront of developing groundwater modeling and well design methods. In fact, many of the groundwater modeling and well design methods commonly used today was developed by our firm.

CULTURE

Culture may be hard to define, but it impacts everything that we do. Our shared values, ways of interacting, and the environment are an important part of our company. Whether its hiring new team members or deciding which projects to pursue, alignment with our culture and values is paramount.
