Groundwater Services

From California to the Pacific Northwest and beyond, our hydrogeologists and water resources experts support municipalities, water purveyors, and irrigators to ensure their water supply needs are met.

For some of our clients, groundwater is the sole source of drinking and irrigation water, and long-term management of groundwater supply is critical. For others, groundwater provides an essential backup supply that adds resiliency and redundancy in the event of drought or surface water contamination.

Featured Services

SGMA Support

In California, where water is scarce, communities must come together to make a plan for sustainable groundwater management. We help basin stakeholders work together to achieve balanced pumping.

Aquifer Storage and Recovery

GSI has long been a champion of using this technology to save water for drought conditions and other innovative applications.

Resiliency Planning

Groundwater is a cost-effective, flexible, and scalable way to develop a backup or redundant supply that can provide critical source of water during an emergency or supply shortage.

Historical Water Use Documentation

Documenting historical water use can protect groundwater-dependent landowners in the event of pumping curtailments.
