Groundwater Resources

Sustainable Solutions

Groundwater resources evaluation, development, and management are central to everything we do

Groundwater resources projects are becoming increasingly complex. We identify pertinent issues to develop strategies that will effectively and efficiently complete your project.

Our highly skilled scientists and engineers integrate scientific methods and forward-thinking engineering approaches, while negotiating legal, institutional, and regulatory constraints.

 

Expertise

  • Sustainable Groundwater Management Act compliance and Groundwater Sustainability Plan development

  • CEQA and NEPA impact analysis, mitigation development, and technical support

Napa County Groundwater Sustainability Planning

Like much of California’s Coast Range, Napa County’s complex geologic history exerts a strong influence on present day water resources management. Throughout the twentieth century, productive agricultural lands, population growth, and limited surface water supplies have had the result of increasing the reliance on groundwater. We advanced the hydrogeologic conceptualization...

Napa Valley Joint Surface Water and Groundwater Monitoring

Lack of data on shallow groundwater conditions near key streams in the Napa Valley was recognized as a data gap affecting ongoing efforts to sustainably manage groundwater resources. We provided critical services to facilitate construction of a new network of dual-completion monitoring wells and surface water monitoring instrumentation to continuously...

Sustainable Groundwater Management Act (SGMA)

We have been immersed in SGMA-related work from the beginning; this includes our service on technical advisory groups to the California Department of Water Resources during the development of the Groundwater Sustainability Plan (GSP) emergency regulations and Best Management Practices for implementation of the Act. Since then, we have assisted...
