Todd Groundwater specializes in the planning, development, management, and protection of
groundwater and related surface water resources. Todd was founded in 1978 by Dr. David Keith Todd,
who was the author of the widely used textbook, Groundwater Hydrology. We are an employee-owned
and California-registered Small Business Enterprise. Our office is located in the City of Alameda,
convenient to the Oakland Airport. Our contact information is provided below:

Our staff is composed of fourteen professionals and two administrative staff. We maintain a small,
specialized team focused on groundwater services. Our professional staff members have advanced
degrees in civil engineering, geology, hydrogeology, geochemistry, geography, and environmental
sciences. All of our geologists and engineers are professionally registered, and most of our geologists are
also certified hydrogeologists and engineering geologists. With an average staff tenure of 15 years, we
provide our clients with reliable and consistent service from a cohesive team.
Over the past 40 years, Todd has provided the full spectrum of hydrogeological and groundwater
management services to numerous private and public clients. Most of our work is conducted for California
public agencies, particularly water agencies, cities, and counties. In fact, 96 percent of our work in 2017
was for state and local agencies, and half of our projects were based in Southern California. Our work for
public agencies includes basin characterization, water supply assessment, groundwater exploration, well
siting, design, and installation, wellfield optimization, water quality characterization and geochemistry,
water supply planning, groundwater flow and water quality modeling, managed aquifer recharge,
environmental impact evaluations, engineering evaluations and annual reporting, and development of
Groundwater Sustainability Plans (GSPs) in compliance with the Sustainable Groundwater Management
Act (SGMA). Because most of our work is for California agencies, we are well versed in the evolving water
code and regulations that guide groundwater management. We also know that our work is for public
agencies; hence we take particular care in providing documents and presentations that are accessible and
useful to staff, stakeholders, and the public.

We are currently working for Valley District and its partners in the Yucaipa Valley to determine the
infiltration capacity of vadose zone sediments underlying proposed recharge areas and are familiar with
groundwater management issues in the basin.
Todd Groundwater has been committed to groundwater basin management for decades. Because of this
work, we not only tracked but participated in development of the SGMA. Through membership of Todd
principals on the Association of California Water Agencies (ACWA) Groundwater Committee, we’ve had
the opportunity since before 2014 to engage regularly with California Department of Water Resources
(DWR) personnel on regulation development. Moreover, Todd principals have helped advance
understanding of SGMA through numerous invited presentations and panels on SGMA (see staff resumes).
Most importantly, Todd Groundwater has been actively engaged in SGMA planning for water agencies,
including completion of a successful GSP Alternative Plan for Zone 7 Water Agency; this work can be
viewed as a “practice run” for the GSP process.
