Geoscience specializes in groundwater modeling, sustainability studies, full-service water
well design and rehabilitation, and recycled water projects. Over the past 40 years they
have completed more than 2,000 groundwater studies including basin-wide sustainable
management, safe yield, well siting, and others.

As a full-service hydrogeologic consulting firm, Geoscience has completed all of the technical components
required in a Groundwater Sustainability Plan. They bring the expertise to complete a full range of
hydrogeologic services, including groundwater and surface water modeling, GIS mapping, monitoring
well and network design and construction, municipal and injection well design and construction,
extensometer design and construction, and subsidence monitoring using InSar.

The Geoscience team has many years of experience evaluating sustainable yield in numerous groundwater
basins, including the Yucaipa Basin. As required for this project, they routinely refine and modify USGS
groundwater models, including MODFLOW. Additionally, the groundwater modeling lead, Johnson Yeh,
collaborates with the USGS to develop models for the Yucaipa and San Bernardino area, and is helping
USGS beta-test GSFLOW. Geoscience will leverage their lessons learned from more than 40 projects
that they have completed for the GSA members, 11 of which were in the Yucaipa Basin.
