Who We Are

The HYDRODYNAMICS GROUP, LLC is an ensemble of some of the country's leading experts in ground water hydrology, and is headquartered in Edmonds, Washington. The group was created by Dr. John Bredehoeft, a nationally recognized expert in hydrogeology, with the vision that a team of seasoned hydrogeologists could provide principal-level consulting expertise for a wide spectrum of water and environmental problems. With The HYDRODYNAMICS Group, principal-level hydrogeologists and engineers do the work. There is no learning at the job's expense. Group members owned consulting, drilling, and managed divisions within major consulting firms and government.

Role of Fluids in Geologic Processes

John Bredehoeft started work in ground water in the 1950's. He worked at the U.S. Geological Survey for 32 years. At the USGS he engaged in both research and high-level management. He is the author of more than 100 research papers in the refereed scientific literature. In the 1970s, Dr. Bredehoeft managed the entire water research program of the USGS. In the early 1980s, he was the West Coast Regional Manager for the USGS, responsible for all water activities of the agency in the eight western states: Alaska, Arizona, California, Hawaii, Idaho, Nevada, Oregon, and Washington.

In 1995, Dr. Bredehoeft left the USGS to start The HYDRODYNAMICS Group. He consulted on a number of the nation's nuclear waste facilities -- Yucca Mountain, Savannah River Plant and WIPP. John is a member of the National Academy of Engineering and the Russian Academy of Natural Science.

MICHAEL J. KING, R.G., C.E.G., C.HG.

Hydrogeology
Environmental Engineering
Gas Storage Engineering
Geological Engineering

Michael King is a Registered Geologist and Certified Engineering Geologist and Hydrogeologist with over 22 years of experience in the field of hydrogeology and environmental engineering. Hydrogeologic projects for which he had primary technical responsibility include characterization and remediation of soil and groundwater contamination, watershed/water resource development and management, aquifer testing and analysis, drilling technology, and groundwater computer modeling. Michael has completed over 30 geoenvironmental projects in the last 10 years and 16 watershed studies in the last 5 years.

Michael was a former owner and Vice-President of ASE Drilling Company and was responsible for the drilling of over 500 domestic, commercial, industrial, and irrigation water wells. His other areas of expertise include drilling technology, hazardous waste management, gas storage engineering, and geotechnical studies. Michael has held positions on Technical Review Committees for EPRI's Pittsfield Compressed-Air Energy Storage Project and the Skagit-Hanford Nuclear Power Plant. He is currently a technical editor for the Association of Engineering Geologist Bulletin.

JOHN R. JANSEN, Ph.D., P.G.

Surface and Bore-hole Geophysics
Hydrogeology
Environmental Engineering
Ground-Water Exploration

Dr. John Jansen is a registered Professional Geologist with over 17 years of experience in the field of surface and bore-hole geophysics and, ground water hydrogeology, concentrating on the efficient development and management of ground water resources, which includes the exploration and development, use, treatment, and protection of ground water based water supply systems.

Dr. Jansen's specialty is the strategic identification of well sites in fracture controlled aquifers, and the testing and isolation of vertical zones of aquifers with water quality problems, such as radium, barium, and nitrates. He has sited over one hundred high capacity water supply wells in the United States and Mexico.

Additional areas of expertise include environmental investigations, well design and well rehabilitation. Dr. Jansen invented the Airburst™ well rehabilitation technology (US patent 5,579,845, International Patents pending). He has authored over 60 publications and technical presentations, and is on the Board of Directors for the Environmental and Engineering Geophysical Society.

Guillermo Paniagua - P.E., Ph.D.

GUILLERMO PANIAGUA, P.E., Ph.D.

Civil Engineering
Soil and Rock Mechanics
Finite Element Analysis

Dr. Guillermo Paniagua, P.E. is a registered Professional Engineer with over 35 years of experience in soil and rock mechanics modeling for dynamic loads. Dr. Paniagua is an expert in soil and rock structural interaction having performed finite element analysis of concrete and steel structures that interact with soil and rock to analyze how the entire system will perform under both static and dynamic loading. He has recently modeled stress fields for a concrete lined tunnel, tieback anchor interaction, combination cantilever H-pile, and mechanically stabilized earth support structure and shotcrete lining of tunnels. He modeled the integrity of the Norton Mine in Ohio for static and high pressure air loads, and prepared conceptual shaft plug designs.

ART RAMIREZ

Associate Consultant
Water Resource Development
Water Quality Management
Technical Spring System Design

Environmental Source Management
Art Ramirez has more than 12 years of diversified bottled water industry experience in the areas of spring water procurement and development throughout the United States. His spring water experience includes:

source evaluation and protection,
water purchase negotiation,
source development and FDA permitting,
water quality control, testing, and
project management.

Mr. Ramirez has also been responsible for the development of historical water utilization analysis plans for several major spring water sources in California. During his tenure in the bottled water industry, he has written several procedures on water quality verification and control, project management training, source development standards, water utilization, and waste minimization planning. Mr. Ramirez recently managed the field development of new spring sources in California, Missouri, and Tennessee.

In addition to his spring development experience, Mr. Ramirez successfully managed the regulatory closure of over 20 hazardous waste facilities at various bottled water facilities throughout the United States. He also is providing technical assistance with the sampling of springs in Death Valley for technical review of the Yucca Mountain Nuclear Waste project.

Art Ramirez is a Consultant working with Hydrodynamics.
