11 Years: Supervisor, Groundwater and Surface Water Planning Section, Water Resources Division, Department of Environmental Protection, Broward County, Florida.
Managed the development of an integrated groundwater and surface water model of the hydrologic system in Broward County. Applied the model to the operation of canal system control structures and municipal water wellfields for water resources planning and management, including municipal water supply, artificial groundwater recharge, saltwater intrusion (salinization), flood hazard, wetlands protection, and surface water and groundwater depletion.
Analyzed aquifer recharge possibilities.
Managed the development of a county wellfield protection groundwater model (MODFLOW).
Managed monitoring and analysis of saltwater intrusion into the karstic Biscayne Aquifer along the Atlantic coast, especially regarding contamination threat to municipal water wellfields. This work included managing a project for computer saltwater intrusion modeling.
Performed surface water quality modeling relative to pollution of surface water.
Managed the development of Geographic Information System (GIS) applications for water resource management.
Represented Broward County on committees and working groups involved in the Comprehensive Everglades Restoration Program, Florida water resource regulation and planning, FEMA flood mapping, and EPA Underground Injection Control (UIC).
Published technical reports on groundwater quality and saltwater intrusion.
Responded to public inquiries on water issues, and presented water information at public meetings.
Concurrent Consulting
Developed a groundwater flow and contaminant transport model (MODFLOW/MT3D) of groundwater contamination by the solvent TCE (trichloroethylene) at Ft. Chaffee, Arkansas, for the U.S. Army Corps of Engineers. Simulated movement of contaminant plume to surface water.
Reviewed documents related to a water well construction contract for a law firm.
2 Years: Independent Consulting Hydrogeologist, Denver, Colorado.
Lead a peer review team in an evaluation of groundwater data, aquifer pumping test analysis, and groundwater modeling used by Sandia National Laboratory, Albuquerque, New Mexico, to support the U.S. Department of Energy (DOE) Waste Isolation Pilot Plant (WIPP) Certificate of Compliance Application for radioactive nuclear waste disposal near Carlsbad, New Mexico.
6 Years: Earth Sciences Manager, Principal Hydrogeologist, Advanced Sciences Inc., Denver, Colorado.
Managed the Earth Sciences Group located in offices throughout the United States involved in hydrogeologic and environmental services.
Managed groundwater investigations at Rocky Flats Plant, Golden, Colorado; and performed groundwater flow (MODFLOW) and contaminant transport modeling for this CERCLA Superfund site.
Developed the groundwater hydrology part of a Remedial Action Environmental Impact Assessment for the DOE's Hanford radioactive materials processing site, Richland, Washington, a CERCLA Superfund site. This work included groundwater and river water radioactive nuclide modeling.

Supervised groundwater modeling (MODFLOW) at Edwards Air Force Base, California, a CERCLA Superfund site.
Provided senior review on groundwater quality monitoring and remediation tasks for various Federal Aviation Administration Sites in the western United States, primarily underground storage tanks.
Provided technical support for subsurface testing for the design of a soil vapor extraction system at the Puerto Rico Air National Guard base for remediation of groundwater pollution by jet fuel.
Performed senior review of numerous landfill regulatory compliance audits for the U.S. Bureau of Land Management.
2 Years: Manager of Hydrogeologic Modeling, IT Corporation, Pittsburgh, Pennsylvania.
Managed corporate hydrogeologic modeling group.
Managed site-wide groundwater flow and contaminant transport modeling for dissolved uranium at the DOE's Feed Material Production Center, Fernald, Ohio, a CERCLA Superfund site.

EARLY CAREER
After receiving a Bachelor's Degree from the University of Illinois and performing military service, I worked as a petroleum geologist with a major oil company in Illinois and Colorado. I worked on petroleum exploration and production in these states plus Wyoming, Utah, New Mexico, Nevada, and Nebraska. I then returned to the University of Illinois for graduate study focusing on hydrogeology, engineering geology, petroleum geology, and petroleum reservoir engineering. I completed a Ph.D. thesis on the hydrogeology of the Stettler Area, Alberta, Canada, which included groundwater modeling of a municipal water wellfield with a computer. Temporary work during summer breaks included petroleum exploration in Saskatchewan and Alberta, and petroleum reservoir analysis in Illinois.
After receiving my Ph.D., I held teaching and research positions at Montana State University, Bozeman; and the University of Toledo, Ohio. I taught undergraduate and graduate level courses in geology and hydrogeology. Research included computer simulation of the hydrologic systems of mountain watersheds, computer simulation of the movement of water through soil, and studying the groundwater system at an industrial park where a groundwater drainage system was installed.
I left the university teaching profession and did extensive consulting in Montana in hydrogeology and geology. I performed numerous investigations that included the following types:
Groundwater contamination due to petroleum, mining, agricultural and other activities,
Groundwater quality assessment and monitoring for petroleum and mining projects, wastewater impoundments, and water resources management,
Water rights expert witness for surface water and groundwater, including effects of water well pumping on nearby wells and streams (stream depletion),
Geothermal resource assessment and geothermal well construction,
Groundwater supply for public water supply and irrigation, including safe sustainable yield assessment,
Water well location, construction, testing, and rehabilitation,
Causes of waterlogging of land (expert witness),
Causes and remediation of saline seeps,
Causes of basement flooding (expert witness),
Flood hazard analysis,
Irrigation ditch design (expert witness),
Slope stability analysis (expert witness and many environmental investigations),
Earthquake hazard analysis,
Snow avalanche hazard analysis,
Coal resource assessment,
Estimating groundwater inflow to proposed open pit coal mine,
Estimating impact of mine dewatering on water wells.
Teaching elementary geology.
Clients included law firms (expert witness), engineering firms, petroleum firms, mining companies, industrial firms, agriculture firms, state agencies, planning agencies, federal agencies, real estate developers, geothermal developers, and a university. Gave numerous depositions and testified in court as expert witness.
