Groundwater evaluations have been an integral part of GEI services for years, supporting efforts to develop groundwater production as well as groundwater recharge. The fundamental elements of groundwater management remain the same: groundwater geology, occurrence and movement of groundwater and groundwater quality. It is this back-to-basics approach that gives GEI the understanding necessary to develop innovative groundwater projects.
Developing groundwater management programs requires detailed studies of yield and quality; conjunctive use of surface water and groundwater; clear understanding of basin hydrology; balancing of municipal and agricultural requirements for quality, reliability and quantity; and the planning, design and construction management of water recharge facilities, well fields and water conveyance facilities. We are proud of our track record integrating these complex studies and facilities to achieve multiple goals and provide an equitable balancing of costs and benefits for clients.

Permitting and Project Implementation
Conservation, storage, allocation, stream diversion and ecological effects must often be considered for permitting any supply system installation or improvement. GEI has an expert team with decades of experience completing expedited environmental services on major water resource projects, from start-to-finish. GEI environmental staff are industry leaders in understanding the complexities of an ever-changing regulatory landscape to solve complex and multi-faceted project issues.

Technical Studies and Groundwater Modeling
Our staff are experienced in applying analytical tools, models and data management and geographic information systems to define hydrogeological conditions, assess surface and groundwater interactions and evaluate land use patterns, as well as estimate current and future agricultural, urban, and environmental demands.

Groundwater Discharge
Water table mounding, flooding and spread of contamination are often concerns associated with proposed groundwater discharges. Permitting generally requires that all these concerns be addressed. GEI’s soil scientists, hydrogeologists and engineers work together to define soil stratigraphy, perform aquifer testing as appropriate and model the system to provide a defensible estimate of the predicted effects.
