What Todd Groundwater does

Todd Groundwater is a specialized groundwater consulting firm founded in 1978 as David Keith Todd Consulting Engineers by Dr. David Keith Todd, author of the textbook 'Groundwater Hydrology' and an internationally recognized expert in groundwater hydrology. The firm, now employee-owned and headquartered in Alameda, California, provides hydrogeologic consulting services spanning groundwater planning, development, management, protection, modeling, and litigation support to water agencies, municipalities, counties, and private clients. Its core technical capabilities include numerical groundwater flow and solute transport modeling using industry-standard platforms (MODFLOW, MT3D, FEFLOW, GSFLOW, PEST, WASP, AQTESOLV) combined with proprietary methodologies — most notably a Salt and Nutrient mixing model approach reviewed and approved by the Los Angeles Regional Water Quality Control Board, and the CoSANA integrated water resources model developed in-house for the Cosumnes, South American, and North American Subbasins.

The firm's service portfolio addresses California's Sustainable Groundwater Management Act (SGMA) compliance through Groundwater Sustainability Plan development, managed aquifer recharge planning and optimization, Salt and Nutrient Management Plans for recycled water projects, water supply assessments, and groundwater contamination characterization. It also provides litigation support and expert hydrogeologic testimony for water rights, contamination, and adjudication matters. Revenue is generated through project-based professional services engagements on a quote-driven, non-publicly-disclosed pricing basis, with no subscription or recurring revenue model. The firm holds Small Business Enterprise (SBE) and Women's Business Enterprise (WBE) certifications that enable public agency procurement, and its go-to-market motion is sales-led through direct engagement, professional conference presence, and thought leadership within the California groundwater community (Groundwater Resources Association, WateReuse Association, ACWA). Operating geographies are concentrated in California with selected projects in Arizona, Texas, Nevada, and Hawaii.
