Hanni Blair
Hydrogeologist
Areas of Specialization
Groundwater Modeling
Groundwater Flow and Transport Modeling
Groundwater/Surface Water Interactions
Groundwater Management
Hanni Blair (formerly Haynes) joined M&A in 2022, bringing experience in groundwater modeling and field work. At M&A, she uses her modeling skills to support efforts toward groundwater sustainability in California. She completed her master’s degree in hydrologic science from the University of California, Davis, successfully defending her thesis on modeling groundwater flow and transport of non-point nitrate contamination at an almond orchard in California’s Central Valley. Hanni’s previous experience in environmental consulting is as a geologist at Tetra Tech, Inc. in Rochester, New York.
