Eros Bilyeu is a professional geologist and certified hydrogeologist specialized in conducting hydrogeological investigations and water resources studies in California, New Mexico, Texas, Alabama, Mississippi, Georgia, and Puerto Rico. Mr. Bilyeu has experience working with high priority basins to implement critical components of the California Sustainable Groundwater Management Act (SGMA) Groundwater Sustainability Plans (GSP), evaluating and designing Aquifer Storage and Recovery (ASR) programs, evaluating and designing Managed Aquifer Recharge (MAR) Programs, designing and implementing supply well replacement or rehabilitation, designing conceptual models and creating numerical groundwater flow models, well and aquifer testing, groundwater budget analysis, basin safe yield assessments, and speaking and presenting to agencies and basin stakeholders. 

Mr. Bilyeu has been integral in the design, construction, and testing of replacement of supply wells for member agencies of Metropolitan Water District of Southern California (MET) such as Eastern Municipal Water District Water District within the San Jacinto Basin in Riverside County, California, completing evaluations for Aquifer Storage and Recovery (ASR) well fields and hydrostratigraphic conceptual models consisting of detailed correlation of oil and water logs for MET member agency Calleguas Municipal Water District and their Groundwater Sustainability Plan (GSP), managing stakeholder engagements with Fox Canyon Groundwater Management Agency (FCGMA), United Water Conservation District and others, and assisted with updating the groundwater model for use of ASR within the Fox Canyon and Grimes Canyon aquifers in Ventura County, California.

Mr. Bilyeu previously worked with international groundwater resources expert Dr. John Cherry from the University of Guelph and Waterloo, and Southern California groundwater resources experts Terry Foreman and Bryan Bondy developing expertise within the local basins in Ventura County and further developing and implementing methods of characterizing diffused fractured bedrock networks within turbidite units at Santa Susana Field Laboratory near Chatsworth, California. Mr. Bilyeu also specialized in characterizing fractured karst bedrock networks in the southeastern United States supporting hydrogeological characterization at NASA Marshall Space Flight Center in Huntsville, Alabama.

Mr. Bilyeu has helped many rural communities in Texas and New Mexico with water supply investigations and refining their conceptual model of their water supply to further the understanding of their community’s future water supply and demand, and plan for the growth of their community and expansion of commercial and industrial enterprises.

Mr. Bilyeu is experienced in high resolution hydrogeological characterization of fractured bedrock networks, karst bedrock systems, large sedimentary and groundwater basin studies, ASR design and optimization, environmental planning, non-aqueous phase liquids (NAPLs), landfills, and underground storage tanks (UST/LUST). Developing, managing, and evaluating studies utilizing surface water, soil and sediment, groundwater, borehole/surface geophysical, aquifer testing, and chemical data. Phase I, Phase II environment site assessments (ESAs), and large long-term groundwater characterization and hydraulic evaluations (LTM).

Mr. Bilyeu is Experienced in geophysical characterization, seismic surveys, petrophysical characterization, resource management, water supply characterization/technologies and regulations, numerical flow modeling and resource and contaminant modeling, basin interpretation and modeling, drilling operations, various subsurface logging operations, and sampling and custody methods.

Mr. Bilyeu is experienced with designing computer systems, software, database administration, and languages/literacy involving geospatial software and modeling applications within large groundwater basins, environmental and industrial contamination fate and transport investigations, water supply investigations, oil/gas exploration/mapping of highly deformed, regional shallow dip reservoirs in the Gulf Coast basins, and mineral/resource/land evaluation.
