GROUNDWATER
Managing and Protecting Groundwater Basins
Full service geohydrology starts on the surface. We model interactions between surface water and groundwater, from figuring out how much rainfall in a basin percolates into the ground, to mapping out interactions between streams and groundwater basins.
Our hydrogeologists and engineers have advanced experience with efficiently recharging water into the ground, along with designing, planning and managing well construction.
WELL SITING & CONSTRUCTION
Robust and Reliable Well Infrastructure
We pioneered the first numerical models of groundwater basins, calculating stored water volume, along with how much water enters through the surface and from the ground.
Today, our digital groundwater models enable management and forecasting for all groundwater basin operations. We also site, design and manage well infrastructure construction for both producing and injecting water.
AQUIFER RECHARGE
Augmenting Groundwater Supplies
Aquifers may need recharging to meet current and future groundwater needs. Municipal and agency clients rely on our deep groundwater basin augmentation experience and Managed Aquifer Recharge expertise.
Using basin-wide modeling tools, we can predict pumping and future augmentation project impacts, as well as support project planning, permitting and implementation to ensure project success.
LITIGATION SUPPORT
Protecting Water Rights
We provide groundwater and surface water rights, and litigation expertise including well design, construction and operation. Clients leverage our technical expertise for simple and complex water rights litigation in the US and internationally.
From strategic case support to developing robust, defendable technical analyses and groundwater models, Geoscience supports client declarations, depositions, and trials. Our groundwater models have never been impeached by an adversarial party in a litigation.
